Logical and consistent concept of navigating and editing text
(without ancient line-end handling limitations or insert/append confusion)
•
Supports various control styles:
•
Editing with command control, function key control, or menu control
•
Navigation by cursor keys, control keys, mouse or scrollbar
•
Concise and comprehensive menus (driven by keyboard or mouse)
•
"HOP" key paradigm doubles the number of navigation functions
that can be most easily reached and remembered by
intuitively amplifying the associated function
•
Immediate adjustment if the window size is changed, in any
state of interaction

•
Support of CJK input methods by enhanced keyboard
mapping including multiple choice mappings (handled by a pick list menu);
characters in the pick list being sorted by relevance of Unicode ranges
•
Han character information with description and pronunciation

•
writing into a pipe (writing edited text to standard output)
•
using a script that starts it in a new window
Examples
mined x
edits the file x
mined x y z
edits files x, y, and z
cmd | mined
edits the output of program cmd;
a file name for saving can be given later
mined x > y
takes the contents of file x and edits it
for writing into y
mined | mail nn
edits a text to be mailed
cmd1 | mined | cmd2
modifies text within a pipe between
program cmd1 (output)
and cmd2 (as input)
minmacs ...
runs mined in emacs-compatible command mode (like mined -e)
mstar ...
runs mined in WordStar-compatible command mode (like mined -W)
mpico ...
runs mined in pico-compatible command mode (alpha)
xmined ...
starts a new terminal window (xterm or rxvt, depending on
current TERM variable setting) and invokes mined in it
umined ...
starts a new terminal window in UTF-8 mode (xterm or rxvt,
depending on font availability and usage capabilities)
and invokes mined in it
wined ...
(on Windows) starts mined in a separate terminal
session, using MinTTY if available, otherwise rxvt
(stand-alone version), either not needing X Windows;
the script applies Windows look-and-feel, and configures
MinTTY to run in UTF-8 mode; the command is provided both
as a cygwin script wined and a Windows
command script wined.bat
Startup options
+number
Mined positions to the given line number.
+/expr
Mined initially searches for the given search expression.
-v
Mined starts in view only mode. The text cannot be modified.
\-\-
Restricted mode (tool mode): no other files can be edited
or otherwise affected.
++
End of options; subsequent file name can start with
"-" or "+".
+x
Make new files executable (Unix).
→NEW→
When cloning a file (with Save As or a similar feature),
or if permissions are restricted by the environment
(umask setting in Unix), executable permission is set
only where also read permission is set.
Line end handling (transparent and transforming)
-r
Convert MSDOS line ends (CR LF) to Unix line ends (LF)
(stripping CR at line ends).
Can be combined with -R
→NEW→
or +R.
Also sets line end type for new files to LF for the djgpp
version (which defaults to CR LF).
+r
→NEW→
Convert Unix line ends (LF) to MSDOS line ends (CR LF)
(adding CR at line ends).
Can be combined with -R
or +R.
Also sets line end type for new files to CR LF.
-R
Convert Mac line ends (CR) to Unix line ends (LF).
→NEW→
Can be combined with -r
or +r.
+R
Recognise Mac line ends (CR) and indicate them on display;
nothing is transformed with this option.
→NEW→
Can be combined with -r
or +r.
+u-u
Interpret Unicode line separator and paragraph separator
as normal characters, not line ends (handling them as
line ends was previously enabled with
-uu and is now on by default).
Character set and character handling
-u(character set)
Interprets edited text as UTF-8,
disables UTF and CJK auto detection.
Synonym of -EU.
-l(character set)
Interprets edited text as Latin-1,
disables UTF and CJK auto detection.
(Used to be +u which is
still valid for compatibility.)
Synonym of -EL.
+u-u(character handling)
Interpret text as UTF-8, but interpret Unicode line
separator and paragraph separator as normal
characters, not line ends.
-c(character handling)
Selects separated display mode for combined characters
(separating base character and combining characters).
This mode can also be toggled from the Options menu or
by clicking on the Combining flag (next to the
character encoding flag) in the flags area.
-b(character handling)
Toggle "poor man's bidi" mode:
input support for right-to-left scripts, based on
Unicode script ranges.
(Enabled by default unless the terminal is detected to
be in bidi mode; so e.g. in mlterm, poor man's bidi
is disabled by default.)
-EX(character set)
Where X is one of B/G/C/J/S/K/H: Selects one of the
supported CJK character encodings for text interpretation
and disables auto-detection of CJK encodings.
For details, see CJK encoding support.
For more details on supported encodings, see the
Character encoding flags listing
in the Mode indication flags section.
-EX(character set)
Where X is one of U/L or another 1-letter character
encoding tag: Selects Unicode/UTF-8, Latin-1, or one
of the other supported character encodings for
text interpretation.
For details on supported encodings, see the
Mode indication flags listing.
-E=charmap(character set)
Where charmap is a character encoding name (as
reported by the locale charmap command):
Selects the respective character encoding for
text interpretation.
For details on locale-related character encoding configuration,
see Locale configuration.
-E.suffix(character set)
Where suffix is a character encoding suffix ("codeset")
as used in locale names:
Selects the respective character encoding for
text interpretation.
For details on locale-related character encoding configuration,
see Locale configuration.
-E:flag(character set)
Where flag is a 2-letter indication used by mined to
indicate the respective text encoding in the Encoding flag:
Selects the respective character encoding for
text interpretation.
For details on supported encodings and their flags,
see the Mode indication flags listing.
-Eu(buffer encoding)
Enables Unicode buffer mode which always maintains the
Copy/Paste buffer in Unicode, thus facilitating conversion
between different encodings being edited.
For details, see
Unicode Copy/Paste buffer conversion.
-E?(character set)
→NEW→
Determine the encoding(s) of the text file(s) given
as parameters by auto-detection, print out the
information and quit.
-KX(input method handling)
Configure the Space key to perform a certain function
in keyboard mapping selection menus
("CJK input method pick lists"), where X is one of:
'n' to navigate to the next choice (like cursor-right),
'r' to navigate to the next row (like cursor-down),
's' to select the current choice (like Enter).
-K=im-im(input method selection)
→NEW→
Select input method and/or standby input method (for
quick switching with Alt-k).
The syntax is the same as for the optional environment
variable MINEDKEYMAP (see below).
+K(input method handling)
(Obsolete with 2000.15 since keyboard mapping is always
enabled by default.)
Enable keyboard mappings (input methods) even in 8-bit
terminal or when editing an 8-bit encoded file; the
characters thus entered will mostly only be displayed
by substitute indications (as most characters anyway
when editing files in an 8-bit terminal not matching the
character set).
Terminal mode
-U(terminal mode)
Toggles UTF-8 screen handling assumption, i.e. selects
UTF-8 screen handling unless UTF-8 keyboard input is
already selected (by another -U
option or environment setting).
In the latter case, -U
deselects UTF-8 terminal operation.
This option should normally not be used as the mode should
be configured in the environment (see
Locale configuration).
+U(terminal mode)
Selects UTF-8 screen handling.
Note that none of the options -U
or +U needs to be used if
the environment is correctly configured to indicate
UTF-8 as it should (see
Unicode handling / Terminal environment).
Also, mined performs auto-detection of UTF-8 terminal
encoding and UTF-8 terminal features (different width
data versions, handling of double-width, combining and
joining characters), so even if the environment is
not correctly configured, mined should work without
this explicit terminal mode parameter.
+UU(terminal mode)
Selects bidirectional terminal support.
This mode implies UTF-8 and also assumes that Arabic
ligature joining (of LAM/ALEF combinations) is
applied; it will be handled by mined accordingly.
+UU-U(terminal mode)
Selects bidirectional terminal support
without Arabic ligature joining (like MinTTY).
-cc(terminal mode)
Assumes that the terminal does not support combining characters.
By default - unless otherwise detected - mined assumes
that combining characters work on UTF-8 terminals and
do not work in CJK terminals.
+c(terminal mode)
Assumes that the terminal supports combining characters.
This is enabled by default for UTF-8 terminals, and
disabled by default for CJK terminals, unless otherwise
detected.
+EX(terminal mode)
Where X is one of B/G/C/J/S/K/H: Assumes a CJK encoded
terminal in one of the supported CJK character encodings.
For details, see CJK encoding support.
+EX(terminal mode)
Where X is one of g/c/j: Assumes a CJK encoded terminal
in one of the CJK character encodings like G/C/J and
also assumes that the terminal cannot display GB18030
4-byte encodings, CNS 4-byte encodings, EUC-JP 3-byte
encodings, respectively.
+EX(terminal mode)
Where X is one of U/L or another 1-letter character
encoding tag: Assumes a Unicode/UTF-8 or Latin-1
encoded terminal, respectively, or an 8-bit terminal
running one of the other supported character encodings.
For details on supported encodings, see the
Mode indication flags listing.
For details on terminal encoding support, see
Terminal encoding support.
+E=charmap(terminal mode)
Where charmap is a character encoding name (as
reported by the locale charmap command):
Assumes the terminal to have the respective encoding.
For details on locale-related character encoding configuration,
see Locale configuration.
+E.suffix(terminal mode)
Where suffix is a character encoding suffix ("codeset")
as used in locale names:
Assumes the terminal to have the respective encoding.
For details on locale-related character encoding configuration,
see Locale configuration.
+E:flag(terminal mode)
Where flag is a 2-letter indication used by mined to
indicate the respective encoding as text encoding in
the Encoding flag:
Assumes the terminal to have the respective encoding.
For details on supported encodings and their flags,
see the Mode indication flags listing.
+E?(terminal mode)
→NEW→
Determine the terminal encoding and further terminal
encoding features and properties by auto-detection,
print out the information and quit.
-C(character set and terminal mode)
(Deprecated.)
Turns a subsequent -E option
(with a single-letter CJK tag) effectively into a
combined -E and
+E option.
So mined assumes the given CJK encoding for both
terminal encoding (unless overridden by UTF-8 terminal
auto-detection) and text encoding.
Can be used for quick indication of CJK terminals
(e.g. cxterm, kterm, hanterm) if locale environment
is not properly set.
+C(terminal mode)
Displays unknown characters on CJK terminal:
Assumes a CJK encoded terminal (e.g. cxterm, kterm, hanterm;
more specific encoding specification is advisable), and
characters encoded in a CJK encoding format are
displayed transparently even if they do not map to a
valid Unicode character.
+CC(terminal mode)
Displays invalid characters on CJK terminal:
Implies +C, but even
character codes that do not match the encoding scheme
(e.g. wrt. to specified byte ranges) are written
transparently to the terminal.
+CCC(terminal mode)
Displays extended characters on CJK terminal:
Implies +CC and overrides
auto-detection of the terminal capability to display
CJK 3-byte / 4-byte codes which would by default
suppress their display if the terminal does not support them.
+D(keyboard assignment)
Setup xterm (by sending dynamic configuration codes) to
apply two useful keyboard handling modes:
Del key on small keypad sends DEL character rather
than an escape sequence and can thus be distinguished
from the Del key on the big (numeric) keypad.
Prepend ESC to character if pressed with the Alt or Meta
key in order to enable Alt-commands (e.g. Alt-f to
open the file menu, Alt-Shift-H to enter HTML markers etc).
(Unfortunately this cannot be done by default as it cannot
be undone because the previous state cannot be detected.)
(This xterm setting should rather be configured permanently
as suggested in the sample file Xdefaults.mined
in the Mined runtime support library.)
Information display
+?c
→NEW→
Enable character code information display on status line.
+?X
→NEW→
Enable character code information display (implies +?c)
with additional information, where X is one of:
•
s: Unicode script
•
n: Unicode character name
•
d: Unicode character decomposition
•
m: mined input mnemonics available for this character
Note: setting any of these options may disable some others
as not all combinations are considered useful.
+?h
→NEW→
Enable full Han character information display as a popup.
In addition to the character description, a set of
pronunciations can be selected with the variable MINEDHANINFO.
+?x
→NEW→
Enable compact Han character information on status line.
In addition to the character description, a set of
pronunciations can be selected with the variable MINEDHANINFO.
+?f
→NEW→
Enable file and position information display on status line.
(On by default since mined 2000.15.)
Note that when editing a file that does not fit
completely in memory (e.g. large file on old system),
this option may cause considerable swapping. In that
case, disable the feature with -?f.
-?X
→NEW→
Deselect the respective +? option.
Editing behaviour
-w
Recognise fewer places as word boundaries for word skip
and delete commands.
-a
Append mode: Append to text buffer or external file for
copy/delete commands instead of replacing it.
+j
Set justification level 1 (or increment level
previously set by environment variable to 1 or 2):
Level 1 initially enables automatic word wrap at line
end when typing over right margin.
Can be changed by clicking on the j/J flag.
+jj
Set justification level 2:
Level 2 initially enables automatic word wrap at line
end when typing within paragraph; buggy.
Can be changed by clicking on the j/J flag.
-j
Set justification level 1 or 2 (other than previously
set).
Can be changed by clicking on the j/J flag.
-T
When moving vertically over a Tab character, stay
→NEW→
left of the Tab column range (on the Tab character).
The default depends on the previous position.
Also, stay left on a wide character when moving
vertically over it.
+T
→NEW→
When moving vertically over a Tab character, stay right of
the Tab column range (behind the Tab character).
The default depends on the previous position.
Appearance
-QX
Select menu border style, where X is one of
•
s: simple border,
•
r: rounded corners,
•
f: fat border,
•
d: double border,
•
a: ASCII border (can be combined with another option -Qs or -Qr),
•
v: VT100 alternate character set graphics border,
•
@: reverse blank border (deprecated),
•
1: (or another digit) add a margin between menu
borders and contents (can be combined with any
other -Q option),
•
Q: stylish selection bar for navigating menu items, see image
(can be combined with another option
-Qs or
-Qr or
-Qf or
-Qd).
•
q: disable stylish selection bar
Mined sets an appropriate default based on its
assumptions of the terminal capabilities.
→NEW→
Enable script colour highlighting (for Greek, Cyrillic...).
(Disabled by default in dark terminals.)
-f
Restrict usage of graphic characters: use cell-grained
scrollbar, simple menu borders, no fancy menu bar for
highlighting the selected menu item.
-ff
Further restrict usage of graphic characters:
no Unicode box drawing graphic characters for menu borders.
-fff
Further restrict usage of graphic characters:
no graphic characters (including VT100 block graphics)
for menu borders.
-F
Assume a screen font with limited coverage of special
symbols and restrict usage of special marker
characters for display of line indications. (This is
needed e.g. for KDE konsole or for xterm using
TrueType fonts.)
Interpretation of the MINEDUTF* environment variables is suppressed.
-FF
Assume a screen font with even more limited coverage
of special symbols and restrict usage of special characters
for indication of selected menu items.
+F
→NEW→
Revert the effect of one -F
option (e.g. preconfigured in the environment variable
MINED) or a corresponding assumption of mined about
the specific terminal which would limit font usage.
+FF
→NEW→
Fully enable usage of characters for special indications.
Further mode selection, interface and display behaviour
-4
Set Tab size to 4 rather than 8.
The effective Tab size can also be toggled while
editing with the ESC T command.
-8
Set Tab size to 8. (May be used on command line to override
Tab size being set to 4 be MINED environment variable.)
The effective Tab size can also be toggled while
editing with the ESC T command.
-+4
Set spacing Tab with size 4; a Tab input character
will be expanded to an appropriate number of spaces.
To enter a real Tab character, type Ctrl-V Tab (^V^I).
The effective Tab size can also be toggled while
editing with the ESC T command.
Tab expansion mode can also be toggled while editing
with the HOP ESC T command.
-+8
Set spacing Tab with size 8; a Tab input character
will be expanded to an appropriate number of spaces.
To enter a real Tab character, type Ctrl-V Tab (^V^I).
The effective Tab size can also be toggled while
editing with the ESC T command.
Tab expansion mode can also be toggled while editing
with the HOP ESC T command.
-P
Hide passwords; enables hidden display of one word
behind the string "assword" in a line (to accommodate
for "password" or "Password"): hidden characters are
indicated by reverse "*" characters.
By default, this mode is activated when editing a file
whose name starts with ".".
+P
Unhide passwords; always display them.
-LN
(N is a number) Define mouse wheel movement to scroll
by N lines (default 3).
Ctrl-mouse-wheel always scrolls by 1 line.
Shift-mouse-wheel scrolls by 1 page.
→NEW→
Mouse-wheel on the scrollbar scrolls by half a page.
-e
Select emacs mode. This assigns
functions to control keys, M-X commands (ESC commands,
using the "meta" key as emacs calls the Alt prefix)
and C-X commands as defined by the emacs editor. Also
the emacs paste buffer ring and cut/paste behaviour is
enabled.
-V
Place cursor before pasted region after paste commands.
(If this option is enabled already, -V acts like -VV.)
-VV
Like -V, and disable emacs-style paste buffer
functions for "delete word" and "delete to end of
line" commands (^T, ^K).
+V
Place cursor behind pasted region after paste commands.
(If this option is enabled already, +V acts like +VV.)
+VV
Like +V, and enable emacs-style paste buffer functions
for "delete word" and "delete to end of line" commands
(^T, ^K).
-W
Select WordStar mode. This
configures WordStar command key layout and enables
many functions of the ^K, ^O, and ^Q menus.
-B
Enforce the Del control character to delete left,
Backspace to move left.
Should normally not be used, see
"Automatic backspace mode adaptation" below.
+k
→NEW→
Enforce usage of terminal "keypad mode" which switches
the numeric keypad to send "application keypad" escape
sequences. This is normally not needed. On certain
terminals, mined will automatically use this mode (e.g.
Linux console), and in terminal emulators it is usually
not needed unless you are running a misconfigured
X windows system in which case you can enable
distinguished keypad functions by using the NumLock
function of the keyboard and switching on this option.
-k
Assign the more usual functions "goto line beginning",
"goto line end" and "delete character" to the Home,
End and Del keys of the right keypad ("numeric keypad").
The (assumedly more useful) mined default is to assign
the frequently used paste buffer functions (mark,
copy, cut) to these keys.
In turn, the assigned functions of the Home and End keys
of the small keypad ("editing keypad") are exchanged to
provide the other function than on the right keypad,
respectively - provided the terminal and its configuration
support this distinction.
Also Alt-Home/End is assigned the respective other
functions so the most useful keypad functions should
always be quite easily available.
Regardless of this switching, mined tries to map
fixed functions to modified Home and End keys:
Ctrl-Home/End for line begin/end movement (both keypads),
Shift-Home/End for the paste buffer copy functions
(small keypad) - provided the terminal, its mode and
configuration support distinction of modified keypad keys.
See also the section on Keypad layout
for a motivating overview of the mined keypad
assignment features and options.
About terminal support and configuration, see
Keypad configuration for further hints.
+*
→NEW→
Enable enhanced mouse control:
Menu items can be navigated with the mouse without
button pressed.
Enabled by default for MinTTY, xterm, gnome-terminal.
-*
Disable enhanced mouse control (if enabled by default
or by previous option), otherwise disable mouse support
altogether.
-**
Disable mouse support altogether.
-M
Suppress display of menu header line (including flags).
Pull-down and pop-up menus can still be opened with
keyboard commands.
→NEW→
Mouse control remains enabled.
-oN
Select scrollbar display mode.
N=0 disables the scrollbar (may speed up editing on
slow remote lines), N=1 enables cell-grained
scrollbar display, N=2 (default) enables finer-grained
scrollbar display on a UTF-8 terminal.
-oo
Selects old (until 2000.14) left/right click behaviour on scrollbar.
-o
Toggles the scrollbar.
-p
Enables distinguished display of line ends and
paragraph ends with different symbols.
-X
Disables display of the filename in the window title bar.
-s
Stay with cursor in top line after page down
or bottom line after page up instead of center line.
-S
Use scrolling for page up/down.
-dN
Apply delay between lines of page output to achieve
visually effective display build-up which may help to quickly
focus on the new cursor position (the screen output is
displayed starting from the cursor position, proceeding
to the screen edges).
If N lies between '0' and '9', the respective number of
milliseconds is applied between display of two lines.
If N='0', still an output flush is performed.
If N='-', no delay at all is applied though still the order
of display output is from cursor position to edges.
Default: '-'; configuration is currently disabled
in the Unix version as 'usleep' doesn't seem to be very
portable.
+p
Enables support for proportional display fonts.
(Not really tested as there doesn't seem to exist a
terminal emulator that handles proportional fonts and
cursor positioning correctly.)
All options are also looked for in the environment variable MINED.
Editing text with mined
Mined is always in insert mode. Commands are single control
characters, double key commands starting with ESCAPE, and a
collection of function keys (for various types of keyboards and
terminals). As a specialty, note the prefixing 'HOP KEY' which
amplifies the effect of certain commands "just as you would expect";
this provides for more command flexibility without having to
remember too many keys. It is described in a separate section
below.
Keypad layout
Control key layout for basic movement functions is topographic
on the left-hand side of the keyboard (an idea originating
from early editors, when keyboards didn't have cursor keypads).
(Although using a cursor block is more comfortable, a simple
set of control key assignments is useful as a fallback on
terminals or remote connections with reduced functionality.)
The right-hand cursor block of typical keyboards is assigned
the most important movement and paste buffer functions.
Keypad assignment features:
•
central placement of HOP key (see below)
•
integration of frequently used copy/paste functions
+------+------+------+
| (7) | (8) | (9) |
| Mark | ^ | PgUp |
+------+------+------+
| (4) | (5) | (6) |

Note that the mined keypad function assignment as shown here
deviates from the more usual assignment of Home/End to
"move to beginning/end of line" and Del to "delete character".
This is deliberately designed to provide more useful functions
to easily available keys, while e.g. line movement can also
easily be achieved with HOP cursor-left or HOP cursor-right,
respectively, and - depending on the terminal configuration -
character deletion may still be done with the small keypad Del key.
This keypad function assignment gives you the
best benefit of keypad usage and is thus considered
much more useful than the commonly expected "standard assignment"
although now and then a user is irritated by it.
As there is often a conflict between the mined keypad assignment
and commonly expected function assignments of some keypad keys,
mined tries to conciliate this issue as follows:
•
Alt-Home/End/Del is mapped to the more common
Home/End/Del function assignments (line navigation and
character deletion).
•
Mined assigns different functions to the Home/End/Del
keys on the numeric keypad and the similar keys on the
small keypad (whenever possible with the terminal) in order
to avoid the waste of resources by the usually redundant
mapping of these two keypad blocks.
•
The -k option switches
keypad function assignments:
Home/End/Del of the numeric keypad invoke line
navigation and character deletion.
Alt-Home/End/Del invoke the paste buffer functions.
Also small keypad Home/End/Del keys are exchanged
accordingly.
•
Using Del without a paste buffer gives an
additional hint on alternative usage.
•
Regardless of -k mode,
Ctrl-Home/End/Del is mapped to the line navigation and
character deletion functions, while Shift-Home/End/Del
is mapped to the paste buffer functions.
•
Note: Keypad function assignments as described
depend on terminal support to distinguish all involved
keys and modifiers which is unfortunately not always
the case.
Terminal support for proper distinction of different
keypads and modified keys may be enhanced by appropriate
terminal configuration, see the manual section on
Keypad configuration.
The HOP function
This function, triggered by any of the HOP keys, amplifies (or
modifies) functions as listed below. To achieve the combined
function, first press any key that is assigned the HOP
function, then any key assigned the second function:
HOP char left
move cursor to beginning of current line
HOP char right
move cursor to end of current line
HOP line up
move cursor to top of screen
HOP line down
move cursor to bottom of screen
HOP scroll up
scroll half a screen up
HOP scroll down
scroll half a screen down
HOP page up
move to beginning of file
HOP page down
move to end of file
HOP word left
move cursor to previous ";" or "."
HOP word right
move cursor to next ";" or "."
HOP delete tail of line/line end
delete whole line
HOP delete whole line
delete tail of line
HOP delete previous character
delete beginning of line
HOP set mark
go to mark
HOP search
search for current identifier
HOP search next
repeat previous (last but one) search
HOP copy/cut
copy or cut, but append to buffer
HOP save buffer
save buffer, but append to file
HOP paste buffer
paste "inter-window buffer",
which is the last saved buffer by any invocation
of mined on the same machine by the same user.
HOP edit next file
edit last file
HOP edit previous file
edit first file
HOP exit current file
exit mined
HOP suspend
suspend without writing file
HOP show status line
toggle permanent status line
HOP enter HTML tag
embed copy area in HTML tags
While a pull-down or pop-up menu is open, any HOP key or the
Space key or the middle mouse button toggles the HOP amplifier
for a function subsequently invoked in the menu; the menu
redisplays with function names changed where applicable.
Character-oriented navigation and editing
From the traditional restriction of Unix tools to the line as a
unit of operation, other editors have derived a line-oriented
movement and insertion paradigm which is a nuisance for
anyone who wants an editor with decently intuitive operation.
Mined handles the end-of-line character like any ordinary
character during movement and editing operations.
Also search and replace strings can contain line ends.
Mouse control and menus
All versions of mined (Unix, DOS/Windows) support mouse operation.
Mouse control operates on pull-down and pop-up menus, flags,
the text area, the bottom line, and the scroll bar,
in order to provide the most useful functions and menu-driven
command selection at hand.

Menus
Mined provides three kinds of menus, all can be opened with
either mouse clicks or commands.
The menus offer the most important editing functions (apart
from simple movement).
Some menus have their items grouped into sections, some of which
have subtitles.
The HOP flag can be toggled while a menu is open with any
of the HOP key, ^G, Space, or the middle mouse button.
When a pull-down menu is opened with the middle mouse button,
the HOP variation is initially triggered, offering the HOP
variations of the menu items.
The three menu groups are used as follows:
•
A pull-down menu is opened by clicking the mouse
on the menu header (in the left part of the top screen line)
→NEW→
or scrolling the mouse wheel on this header.
Shortcut: Each pull-down menu can also be opened
with ESC or Alt and the small initial letter of the menu
header (Alt-f or ESC f for the file menu etc.).
•
A flag menu is opened by clicking the
right mouse button on a flag indication in the flags area
(right part of the top screen line)
→NEW→
or scrolling the mouse wheel on it.
The flag menus have optional markers in front of each item
showing which items are currently active.
Shortcut: The Info menu, Input Method (Keyboard
Mapping) menu, Smart Quotes menu, Encoding menu can also be
opened with Alt-F10, ESC I or Alt-I, ESC K or Alt-K, ESC Q or
Alt-Q, ESC E or Alt-E, respectively.
•
The pop-up menu is placed above the text area and
can be opened with a right-click or Alt-Space (ESC Space).
Menu navigation
When a menu is open, the cursor-left or cursor-right keys
cycle through the pull-down and flag menus.
Alt-cursor-left and Alt-cursor-right navigate quickly between
the two sets of menus (pull-down or flag menus).
When a sub-menu is open, cursor-left goes back to the
parent menu, cursor-right opens its next menu to the right.
There are three methods to navigate within a menu:
•
With the keyboard: open menu as described above, navigate
with cursor keys or by typing the first letter of the desired
menu item (which cycles through all items starting with that
letter, or
→NEW→
containing a word starting with that letter);
activate menu item with Enter key.
•
With mouse clicks: open menu with click (and release)
mouse button, switch to other menu with another click, click
on item to activate it. The mouse wheel may be used to navigate
menu items.
•
With mouse dragging: open menu with mouse button (left or
right), browse menus and items with button held down, activate
selected item with releasing mouse button.
Methods may be mixed, e.g. open a menu with either mouse click
or keyboard, navigate with mouse wheel, then select with Enter.
When selecting a menu item, in most cases the associated function
is carried out and the menu closed afterwards.
→NEW→
In some cases, an option is toggled and the menu stays open
(esp. in Info menu: Han info pronunciation selection,
character information "with" attributes selection).
Scrollable menus: In a low-height terminal (e.g. 24 lines),
longer menus (especially the Encoding menu and the Input Method
menu) may not fit on the terminal. All menus are scrollable
with cursor keys, including Page Down/Up, Home, End keys.
When the window size is changed, open menus are closed in
order to prevent resizing and repositioning problems; this is
planned to be enhanced in a future version.
Hints
Note: Your mouse driver or Windows system may be
configured to generate multiple (e.g. 3) mouse wheel events on
one mouse wheel movement (e.g. with Windows). An option
-L1 could compensate for that
scaling (as mined applies a mouse wheel factor by itself which
is 3 by default).
Layout configuration: See Menu
display below for configuration of menu appearance.
Configuration hint: On Unix, in order to make Alt work
as a modifier, set the xterm resource metaSendsEscape to true
and the rxvt resource meta8 to false as suggested in the
example file Xdefaults.mined in the
Mined runtime support library.
(With older versions of xterm, setting eightBitInput to false
may be required instead; this xterm option doesn't actually
disable 8 bit input as its name might suggest.)
With xterm, this setting can also be enforced dynamically with
the +D option.
Inter-window paste buffer
Mined can perform copy/paste operations within different
editing sessions (parallel or subsequent invocations of mined):
The command HOP Ins (e.g. ^G ^P) will insert the most
recent paste buffer copied or cut in any of the user's mined
sessions.
This can also work remotely in a network; to configure this
features, see
Common paste buffer configuration.
Multiple paste buffers
Mined provides emacs-style multiple paste buffers that
are organised as a buffer ring. Every buffer cut or copy
operation (that places the text between the marked and the
current position to the buffer) creates a new buffer and
stacks it to the list of buffers.
If the feature "deleted word/line appends to buffer" is enabled
(+VV) the commands delete-end-of-line
(^K), delete-word (^T) and delete-end-of-sentence (currently
emacs mode only) append to the top buffer (disabled with the
option -VV).
To paste a non-top-most buffer, paste the most recent buffer
first as usual, then use the buffer-ring command
(Alt-Ins or Ctrl-F4, or M-y in emacs mode) to
exchange the pasted text with the previous buffer. This
can be repeated, going down the stack of buffers, and at
its bottom, starting over from the top again.
Text position markers
A default marker for quick use and additional 10 numbered
text markers are available.
Marker 0 has a special function: 1. it is set when opening a
file at the memorized position, 2. whenever a new current
marker is set, the previous one is pushed to marker 0.
Text position marker stack
In addition to the explicit text markers,
mined implicitly maintains a marker stack to support navigation
and orientation when browsing files.
Whenever a command moves the position by a far distance
(Go to marker, Go to line, Go to file beginning/end,
Go to next/previous file, Search functions including Search
identifier definition across files, Replace with confirm), the
current position is first pushed to this stack.
Later, in order to return to the previous position, use
the command ESC Enter (Alt-Enter) to move along the positions
in the marker stack.
The command HOP ESC Enter (HOP Alt-Enter) moves again forward
along the stack.
Paragraph justification / word wrap
Manual paragraph line/word wrap is invoked with the
justify command (ESC j or ESC J); it justifies the current
paragraph (wraps its lines/words) according to the effective
margins and paragraph termination mode.
Clever justification: With ESC j, mined automatically
determines left margins depending on the current paragraph and
line contents. Heuristic detection of numbered items will trigger
automatic indentation.
Normal justification: With ESC J, mined justifies
strictly according to the margin values currently configured.
See commands listing below "ESC j"
for margin setting commands.
Paragraph termination modes:
Two different definitions of paragraph end are available.
•
The primary mode is to add a space at the end of each line
when the paragraph continues and to end the line without
space where the paragraph ends. This seems an intuitive
way and as a big advantage over other approaches, it is
transparent with respect to visual formatting, i.e. no
text property is required that would affect visual layout
of the text.
Note: Additional visual support of paragraph end
detection is available with the mined option -p that
distinguishes paragraph/line end display.
•
The other word-wrap mode is to add an empty (blank-only)
line after each paragraph. Obviously this imposes more
additional requirements on text formatting discipline and
reduces freedom of text layout.
The mode in effect is indicated in the mode indication display;
see description there.
Auto indentation
By default, mined acts in auto-indent mode: When you enter a
newline, the following line will be filled with the same
prefix of space characters (Space or Tab) as the current one.
This option can be toggled from the Options menu.
A new line without auto indentation can be entered
with the ^O command.
Auto indentation is automatically suppressed if text is entered
very fast (by heuristic detection of input speed) in order to
allow unmodified copy and paste using terminal mouse functions.
Structure input commands
A pair of parentheses with matched indentation can be entered
by prefixing a parenthesis character with HOP.
For example, HOP "{" would enter a pair of "{" "}", both
auto-indented on their respective new line. Other pairs are
"(" ")", "[" "]", "<" ">".
HOP "/" enters an indented Javadoc comment frame.
Back-Tab (Undent function / reverse indent)
A Backarrow key from a position that is only preceded by white
space on the line and on the line above will revert the input
position to the previous matching indentation level.
To avoid auto-undentation ("Delete single"), use
Ctrl-Backarrow or F5 Backarrow to delete only one character left.
(Ctrl-Backarrow only works if configured in your X
configuration, see the example configuration file
Xdefaults.mined in the Mined
runtime support library.)
Tab expansion
With one of the options -+4
or -+8, a Tab key input will be
expanded to an appropriate number of Space characters instead
of inserting a Tab character. You can still insert a literal
Tab character with Ctrl-V Tab.
Search and replace multiple lines
Mined has overcome the typical Unix tool limitation of line
orientation in search operations.
Search and replacement patterns can contain embedded newlines.
Enter a newline (linefeed character) in the search string with
^V^J or \n (or \r to match CRLF newlines).
(In some cases there are still display problems; then update
the screen with the ESC "." command.)
Header line underlining
The command HOP "-" (e.g. Ctrl-G -) underlines the
header line before the cursor position with as many "-"
characters as needed; it applies to the current line unless
the cursor is at a line beginning in which case it applies to
the previous line.
Automatic backspace mode adaptation
There is much confusion about what character codes are delivered
by the Backarrow and Del keyboard keys in different
operating environments and configurations.
For proper operation, the "stty erase CHAR" configuration should
generally be set correctly to reflect the actual code emitted
by the terminal.
Mined detects this setting and adjusts its handling accordingly,
so that the "Backarrow" key should normally work as expected
(delete a character left).
Overview: input support features
Character input
Mined provides several methods to support input of special
characters that may not be easily available on the keyboard.
•
Accented and mnemonic input support
defines Accent prefix keys
to compose accent combinations with subsequently entered characters.
•
It also provides
Character input mnemonics for
easily memorisable input of a wide range of characters,
including most composed Unicode characters.
•
Input support commands
include a quick shortcut for two-character mnemonics.
•
Input support commands
also provide for character input by hexadecimal / octal / decimal
character code or Unicode value, including support for
subsequent entry of multiple numeric characters according to
ISO 14755.
•
Keyboard mapping switching the keyboard
to support another script.
This mechanism also provides CJK input methods.
Structured input
•
HTML tag input
(starting/closing or embedding marked text).
•
Auto indentation and Back-Tab.
•
Structure input commands:
Input of indented matching parentheses and Javadoc frames.
•
Paragraph justification (line/word wrap).
•
Header line underlining
Special features
•
Smart quotes
automatic transformation of entered straight quote marks into
typographic quotation marks (style can be selected in flags area),
as well as smart dashes and other smart text replacements.
•
Right-to-left script input support.
Handling files with mined
Tags file support
The ESC t command moves to the definition of an identifier
(on which the cursor should be placed) using the tags file
(generated by the ctags command).
HOP ESC t prompts for an identifier. (Also available from
search or popup menu.)
If a new file is opened for this purpose, the current
file is saved automatically.
Like with a number of positioning commands, ESC t places
the current position on the position marker stack before going
to the location of the identifier definition. The command ESC
Enter (Alt-Enter) moves back to that position, also saving the
current file if needed first.
Data security
Mined has a robust and defensive concept of handling edited
text and file contents in case of any kind of program or
system errors.
Edited text
Every care has been taken to prevent loss of the edited text
in case of save errors or accidental quit commands etc; mined
always prompts before discarding any modified text (not all
popular editors are so careful about this, e.g. emacs when
editing text without associated filename).
In the rare case of an unrecoverable error (out of memory
or terminal I/O error) or if mined is interrupted by an
unexpected signal, mined needs to terminate but it tries to
save the edited text (if modified) into a panic file
in one of the directories $MINEDTMP, $TMPDIR, $TMP, $TEMP,
/usr/tmp, or /tmp (whichever variable is defined first and
directory is writable in this order).
If possible, mined also tries to continue normally after panic
handling unless multiple external signals are nested.
Only if the temporary area happens to be full and mined cannot
continue either you would be out of luck.
If mined is sent an explicit SIGTERM signal it tries to
terminate normally, writing modified text to the file being
edited (this would involve normal interactive handling if that
file is read-only or the file name was changed).
Files
Also, if any command is issued to write to a file not
previously read in (after change of file name or working directory,
or with a Copy to file command), mined prompts for confirmation.
File access permissions
When creating a new file, its access permissions are set
according to the default behaviour set in the user
environment (umask setting in Unix).
→NEW→
However, when cloning a file (with Save As / Set Name / ESC n
/ ESC d), file access permissions of the originally opened file
are preserved and cloned.
The +x command line option adds
executable permission to newly created files
→NEW→
but only to those users that are also given read permission
by the rules above.
Pipe output
In the "write to standard output" mode (i.e. when invoked
within a pipe), only one "file save" operation can be performed
writing to standard output.
If more than one such operations are issued (e.g. using the
ESC w / F2 , F3, or suspend command) only the first one
will write the text buffer to standard output; any subsequent
one is treated as usual (with empty file name).
Line end modes and binary-transparent editing
Mined is binary transparent. It can handle all types of
line ends (Unix, DOS, optionally Mac, and Unicode separators)
simultaneously in the same editing session. They are indicated
by different visible line end indications. Files without
trailing line end can be edited and created (using the delete
character right function on the last line end). NUL characters
are handled as virtual line ends. Lines too long for internal
handling are split transparently (with a "none" virtual
line end).
Character codes that are illegal in the currently selected
text encoding are maintained transparently and are clearly
indicated (e.g. illegal UTF-8 sequences in Unicode text).
Files with mixed encoding (e.g. UTF-8 / 8 bit sections) can
be edited comfortably.
Input: To enter a NUL character, use ^V # 0 or
^V < NUL or Ctrl-Space > (if the keyboard supports
the latter).
Memory of file position and editing style parameters
If the current directory contains a file named @mined.mar ,
file position memory is enabled.
The current cursor position is stored with every file save
command (even if no write is performed because the text has not
been edited).
When editing that file again, mined will automatically move to
that position (and set text marker 0 to it).
(The association of the position is not with the file itself
but with its relative name from the current directory.)
This mechanism is enabled in each directory by using the
command "Save Position" from the File menu, or by using
Ctrl-F2 to save a file or by prefixing any file writing
command with HOP. This enforces creation of the marker file.
→NEW→ Note: With mined 2000.14, the saved position is changed
from the screen column to the actual character position. This
makes a difference in two cases: when the current position
is within a combined character, and when the same file is
opened in terminal windows with different width properties.
Previously stored visual positions are handled compatibly,
but when a file is stored with new position memory mode
and reopened with an older version of mined (e.g. on a
different machine), the column position would just be set
to 0.
→NEW→ Note: With mined 2000.14, mined applies "housekeeping"
to the position entry for the current file, i.e. it removes
old entries for the same file name.
Note that this housekeeping is, however, only done for the
file being edited, not for other files listed in the marker
file. Also note that old style file position memory is used on
PC versions (e.g. djgpp) as updating the marker file does not
appear to work there.
In addition to the current position, mined also stores the
paragraph justification margins (only if automatic paragraph
justification is active) and the selected Smart Quotes style.
Page length
The command ESC P sets the number of lines that mined assumes
to be on a page. So the status line can contain the page
number to make finding the current position in a print-out
easy. Also the Goto Line/% command (^G etc.) accepts a final
'p' or 'P' in which cases it positions to the top of the given
page.
This information will be associated and stored with the file
name if file position storing is active (i.e. if the file
@mined.mar exists in the current directory).
File names
When entering file or directory names, the leading ~ notation
to refer to one's home directory is accepted.
Restricted mode (tool mode)
Restricted mode is activated with
<code>mined \-\- [ filenames ... ]
In restricted mode, only the file opened when mined was started can
be edited, no commands changing file name reference, involving other
files (copy/paste), or escaping to a shell command will be allowed.
(When mined is invoked without filename argument, a file name
will be prompted for despite restricted mode, however.)
Version control integration
From the File menu, checkout and checkin commands are
available that invoke "co" or "ci" scripts, respectively
(which must reside in the user's command search path).
This offers a gateway to ClearCase or other version control
systems; mined applies automatic save or screen update
as appropriate.
Printing
From the File menu, a print command is available that
prints the text currently being edited.
If the script uprint is installed and configured
properly, printing works in any selected character encoding.
See Printing configuration for further
details.
→NEW→
Under Windows, if neither of the formatting tools paps
or uniprint happens to be installed,
uprint uses notepad /p for printing.
The djgpp-compiled version calls notepad /p directly.
Note: The font size interactively configured in notepad
also affects the print size; a font size of not more than 10pt
gives you at least 80 characters per line; if 72 characters per
line are enough, you can use 11pt font size.
Working with mined
Mode indication flags
The right side of the top menu bar displays a number of
one-letter or two-letter indications for certain modes;
the associated flag menus can be opened from here with a
mouse right-click, or the modes can be toggled quickly with
a middle-click.
(Keyboard shortcuts for handling flags and menus are also
available.)
•
Information display mode
•
"?": this flag menu offers options
for permanent File info, Char info, or
Han character information display.
For Char info and Han info, further options
can be selected to configure the information shown.
(Note that in extreme situations, permanent
File info display might cause swappping (when
editing a file that does not fit completely in
memory, e.g. large file on old system). In
that case, disable the feature.)
•
(In non-Latin-1 text and terminal mode only)
Input Method (Keyboard Mapping)
•
"\-\-": no keyboard mapping
is active.
•
"...": a two-letter
input method tag indicates that an according
keyboard mapping is active,
mapping keyboard input to characters of
the selected Unicode script range, or
using a more complex CJK input method involving
"pick list" selection menus.
See Keyboard Mapping and Input
Methods below.
•
Right mouse button on this indication opens a
menu for selection of the desired keyboard mapping.
•
Left mouse button on this indication toggles between
the current and the previous selected keyboard mapping.
Note: In the open Input method menu,
the last column indicates the source of the input method
with a short tag as follows:
•
"U":
generated from Unicode data file UnicodeData.txt
•
"H":
generated from Unihan database Unihan.txt
•
"C":
transformed from cxterm input table
•
"M":
transformed from input method of the m17n project
•
"Y":
transformed from yudit keyboard mapping file
•
"V":
transformed from vim keymap file
•
"X":
transformed from X keyboard mapping file
•
Smart Quotes
•
Two quote marks are displayed that act as
automatic "smart quotes": When you type a «"»
or «'» character (straight double or single quote),
it is replaced by an opening or closing typographic
quote mark (double or single, respectively),
depending on the text context.
•
Right mouse button on these indications opens a
menu for selection of the desired quotation
marks style.
•
Left mouse button on this indication toggles
between the current and the previous style
selected with the menu.
•
Character encoding (used for text interpretation)
•
A two-letter character encoding tag indicates
the text encoding currently assumed for display.
Changing the encoding changes the interpretation
of the text which is otherwise handled
transparently; it does not recode the text.
•
Right mouse button on these indications opens
a menu for selection of the desired quotation
marks style.
•
Left mouse button on this indication toggles
between the current and the previous selected
encoding.
Note: See
Character encoding support below for a list of
encodings that are auto-detected.
Note: For hints on pre-selecting preferred
text encoding (as well as terminal encoding) and a note
on adjusting the available encodings and configuring
the Encoding menu, see
Locale configuration.
•
"U8":
Unicode/ISO 10646 character set / UTF-8 encoding
•
"16" or "61":
Unicode character set / UTF-16 encoding
(big-endian or little-endian, respectively)
In contrast to the other encodings, UTF-16
has no separate entry in the Character encoding
menu as its internal handling is UTF-8 and
cannot be switched while editing; these two
flag values only indicate that the file being
edited was found to be encoded and will be
saved in UTF-16.
•
"L1": Western
"Latin-1" character set / ISO 8859-1
•
"WL":
Windows Latin character set / "codepage" 1252
(superset of Latin-1)
•
"L9": Western
"Latin-9" character set (with Euro sign) / ISO 8859-15
•
"Cy":
Cyrillic character set / KOI8-RU encoding
(Russian, Ukrainian, Bjelorussian)
sub-menu more Cyrillic:
•
"Ru":
Cyrillic / Russian KOI8-R encoding;
used if locale environment indicates this as
terminal encoding, not in menu, use
"Cy" instead
which combines KOI8-R and KOI8-U
•
"Uk":
Cyrillic / Ukrainian KOI8-U encoding;
used if locale environment indicates this as
terminal encoding, not in menu, use
"Cy" instead

Scrollbar
By default, mined displays a scrollbar at the right side. It
may be used for position indication within the text and for
relative or absolute positioning with the three mouse buttons.
In a UTF-8 terminal, mined uses Unicode character cell
vertical eighths characters U+2581..U+2587 for a fine-grained
scrollbar display. If your Unicode font doesn't include those
block characters, you may switch to the cell-grained scrollbar
with the -o1 option.
Text position marker stack
On commands that jump away from the current position (HOP Mark,
File Begin/End, Search, Search identifier definition, Search
current character, Goto Line/%, Goto Next/Previous File),
the current position is remembered in a position stack.
The command ESC Enter goes backward, HOP ESC Enter forward
in this "stack", even if this means switching the file
being edited.
Structured editing support
HTML support: syntax highlighting and tag entry/matching
HTML tag entry: With the ESC H commands,
opening and closing HTML tags can be entered or (with HOP) a
marked area can be enclosed into HTML tags.
Syntax highlighting: HTML tags are displayed in
light blue colour to set them back from the actual text
contents.
Other highlighting modes apply to HTML comments and JSP code.
This option is activated if the file name suffix is
one of .html, .htm, .xhtml, .shtml, .sgml, .xml, .xul, .jsp,
.asp, .wsdl, .dtd, .xsl, .xslt;
it can be toggled from the Options menu.
HTML tag matching: With the ESC ( or ESC ) command,
mined searches for the opening / closing HTML tag
corresponding to the current one.
Note: While you edit within a line and change its HTML
ending status (by entering or deleting '<' or '>'), the
display status of subsequent lines is not changed. (You may
refresh the display with ESC ".")
Configuration hint: The colour used for displaying HTML
tags can be configured with the environment variable MINEDHTML
using an ANSI sequence, e.g. MINEDHTML=34 (the default).
Search structure match
With the ESC ( or ESC ) commands, mined searches for a matching
end of various structures, like opening/closing HTML/XML tags
(see above), matching parentheses or brackets, matching
comments (/* */), matching conditional macros (#if...),
mail messages (in a mailbox file), MIME attachments.
See the ESC ( command in the command
reference for details.
Structure input
A structure template with opening and closing ends can be
inserted with the structured input feature. HOP followed by
one of { , ( , [ , < enters a corresponding bracket pair,
HOP / enters a Javadoc comment frame. HOP - enters an
underlining line matching the previous line.
Visual structure input is supported by
Auto indentation
Password hiding
With the option -P, mined hides
one word (separated by white space) behind the string
"assword" in a line (to accommodate for "password" or
"Password") and displays reverse "*" instead.
Password hiding can be disabled with +P.
By default (without any P option),
password hiding is activated when editing a file whose
file name starts with "." (Unix "hidden" file convention).
Long line splitting
Mined has an internal line length limit (> ca. 1024 characters).
When opening a file, longer lines are split. This is handled
transparently as virtual "none" line ends are used and indicated.
When saving the file, lines will be joined again.
Visible indication of line contents and display
Various options are available to indicate line control characters
(Tab and line-feed) as well as shifted line display (of lines
longer than the screen width).
(So you can see how many dummy blank spaces there are before the
line ends or how many superfluous blank spaces precede a Tab
character.)
Environment variables can be used to modify these indications. See
Display of contents indications and scrollbar
for details.
Default indications and according configuration variables:
«
LF (Unix-type line end)
customise indication with MINEDRET or MINEDUTFRET
(may contain up to 3 characters to configure different
appearance behind the line end)
«
CRLF (MSDOS-type two-character line end)
on black and white terminals, µ is used instead
customise indication with MINEDDOSRET or MINEDUTFDOSRET
«
CR (Mac-type line end)
on black and white terminals, @ is used instead
customise indication with MINEDMACRET or MINEDUTFMACRET
transparently handled and displayed with
+R command line option
º
NUL character (pseudo line end)
¬
"none" line end (virtual line end as used to split
input lines too long for internal handling; will be
joined into a single line when saving the file)
·
no-break space (Unicode character U+00A0)
«
Unicode line separator
¶
Unicode paragraph separator
customise indication with MINEDPARA or MINEDUTFPARA
¶

line extending the end of the screen line
(move cursor right to shift line display)
customise indication with MINEDSHIFT or MINEDUTFSHIFT
«
line shifted out left of the screen line
(move cursor left to shift line display back)
customise indication with MINEDSHIFT or MINEDUTFSHIFT
·
position spanned by Tab character
customise indication with MINEDTAB or MINEDUTFTAB
(may contain up to 3 characters to configure different
appearance within the Tab span)
Configuration: Display colour of the indications which
are by default red can be changed with the environment
variable MINEDDIM, display colour for Unicode line end
indications with MINEDUNIMARK. Their values should be the
numeric part of an ANSI terminal control sequence, e.g. 31 for
red, "33;44" for yellow text on blue background.
→NEW→
MINEDDIM can also be set to an empty value to have mined apply
dim colour to the indications; the colour value is computed from
the current foreground and background colours (works in xterm).
For more details and recommended settings see the example
script file profile.mined in the
Mined runtime support library.
Default values are compiled in and can be overridden by setting
the variables to empty values.
Note: With the -F option,
mined limits usage of special characters for line indication
and suppresses the interpretation of the MINEDUTF* environment
variables.
Function key help bars
For quick reference of functions attached to function keys,
modified function keys, and other modified keys (as used for
accent prefix functions), a number of help bars can be
displayed in the bottom line.
F1 followed by another F1, optionally modified by a combination
of Control/Shift/Alt, displays a help line with function
attachments to the respectively modified function keys; F1 followed
by Ctrl-1/Alt-1/Alt-Ctrl-1 or Control with a punctuation key
(e.g. Ctrl-,) displays a help line for the respective accent
prefix functions attached.
See the F1 help bars command reference for details.
Menu display
Menu borders are displayed using Unicode Box Drawing characters
in a UTF-8 terminal, using VT100-mode block graphics
characters if they are detected to be available, or using
ASCII graphics otherwise.
Configuration hint: The menu style option
-Q is available to configure your
style preference; see also
Terminal interworking problems for configuration hints
to deal terminal-related graphics display trouble.
Alternatively, the option -f reduces
font assumptions and adjusts usage of special characters accordingly.
In addition to round or rectangular corners, also fancy
item selection display style can be selected
(-Q).
With a non-UTF-8 terminal, if your system's
termcap/terminfo database does not indicate the VT100 block
graphics capability for the terminal you use but you know (or
want to try if) your terminal has that capability, use of
graphical borders can be enforced with the
-Qv command line option.
Configuration hint: The colour of menu borders can be
→NEW→
changed with the environment variable MINEDBORDER.
The marker of selected items in flag menus can be changed with
the environment variable MINEDMENUMARKER.
Language support
Most of the information in this chapter is redundant. It
collects language-specific features described in the other
chapters in a more technical context, here assorted by
languages / scripts for more convenient quick reference.
An overview of typographic quotation marks support
is given at the end of this chapter.

Input method
Mined supports a built-in input method for Greek.
Select it from the Input method menu.
Accented character input support
In combination with a Greek input method or keyboard,
→NEW→
mined provides accent prefix support for both monotonic Greek
and polytonic Greek.
Monotonic Greek uses only one accent, the tonos which
looks like acute and can be entered with the F6 or Ctrl-'
prefix function.
Polytonic Greek uses - among many others -
the oxia accent which is nowadays considered identical and looks
like the monotonic tonos. However, for historic reasons, there
are two sets of Greek accented letters with this accent in
Unicode, one with tonos and one with oxia. While this may be
considered a design flaw of Unicode, in fact both kinds of
characters exist and mined provides support for both accents.
The choice of usage is up to the user.
Note, e.g. that
F6 < alpha >
enters the Greek letter alpha with tonos
Ctrl-F6 < alpha >
enters the Greek letter alpha with oxia
Likewise, with mnemonic input
^V ' < alpha > (using the apostrophe key)
enters the Greek letter alpha with tonos
^V ´ < alpha > (using the acute accent key)
In these examples, < alpha > indicates the Greek letter
alpha, which may e.g. be entered by selecting the Greek input
method and typing the a key.
Accent prefix functions for Latin letters are reused for Greek
accents, see the following table:
F5
Ctrl-:
Ctrl-"
dialytika

For polytonic Greek, 2 or 3 accents can be combined by
applying the respective accent prefix functions in sequence.
For convenience, the most frequent combinations of 2 accents
are also available as dedicated accent prefix keys as listed
above.
Also, modified Ctrl-/Alt-/Alt-Ctrl- digit keys are used for
polytonic Greek accent prefix functions.
See Character input support
for more details.
Script highlighting
To distinguish some Greek letters from Latin look-alikes,
Greek is by default displayed with colour highlighting.
Language-specific case conversion
Case conversion of final sigma is handled properly.

Alternatively, mnemonic character input can be used.
See Accented and mnemonic input support
for details, and see below for some introducing comments.
An accent prefix can either be applied to the plain Latin base
letter, or to a precomposed Vietnamese letter which already has
one of the accents.
These are:
U+00C2 LATIN CAPITAL LETTER A WITH CIRCUMFLEX
U+00E2 LATIN SMALL LETTER A WITH CIRCUMFLEX
U+00CA LATIN CAPITAL LETTER E WITH CIRCUMFLEX
U+00EA LATIN SMALL LETTER E WITH CIRCUMFLEX
U+00D4 LATIN CAPITAL LETTER O WITH CIRCUMFLEX
U+00F4 LATIN SMALL LETTER O WITH CIRCUMFLEX
U+0102 LATIN CAPITAL LETTER A WITH BREVE
U+0103 LATIN SMALL LETTER A WITH BREVE
U+01A0 LATIN CAPITAL LETTER O WITH HORN
U+01A1 LATIN SMALL LETTER O WITH HORN
U+01AF LATIN CAPITAL LETTER U WITH HORN
U+01B0 LATIN SMALL LETTER U WITH HORN
Examples: Suppose your keyboard is mapped to have
Vietnamese characters like A with circumflex available. Then:
^V Â ' (Ctrl-V A-circumflex apostrophe)
enters the composite character U+1EA4 (A with circumflex and acute)
^V ~ Ô (Ctrl-V O-circumflex tilde)
enters the composite character U+1ED6 (O with circumflex and tilde)
Ctrl-6 A
enters U+00C2 (A with circumflex)
Alt-4 A
enters U+1EAA (A with circumflex and tilde)
Ctrl-Alt-3 A
enters U+1EB2 (A with breve and hook above)
Ctrl-Alt-3 O
enters U+1EDE (O with horn and hook above)
Note: Since mined 2000.12, the usage of composite
base characters in mined character mnemonics or accent prefix
combinations as just described also works in non-UTF-8 text
encoding mode (e.g. in VISCII or TCVN encoding).
Thai
Character sets
In addition to Unicode, mined supports the TIS-620 character
set (with CP874 extensions).
To view and edit a file in this encoding, select it from the
Encoding menu (section "Thai"), or use the respective command
line parameter -ET.
See Character encoding flags for details.
Terminal: If your terminal runs this encoding, make
sure to indicate this properly with an environment variable
(LC_* / LANG).
See Terminal environment for details.
Input method
Mined provides a built-in Thai input method.
Select the input method from the Input method menu.
Accented character input support
Not yet implemented. Tell me if you have a proposal or preference
for assignment of accent prefix functions to the keyboard.

Character handling support
This chapter describes mined features for character
manipulation and display of characters and character
properties. Unicode and CJK specific features are described
in the respective chapters.
Character input support is
described separately in the subsequent chapter.
Script highlighting
It may be desirable to distinguish characters in different
script by displaying their glyphs in different colours.
(This especially allows to distinguish easier between
similar glyphs as they occur in Latin/Greek/Cyrillic scripts.)
Script highlighting is currently pre-configured for
Greek and Cyrillic. It uses the terminal's 256-colour mode
if available.
The scripts to highlight and the colour values to use
can be configured at compile-time.
See Mined configuration below.
Combining characters
When editing text in Unicode or any encoding that contains
combining characters, mined supports display and editing of
combining and combined characters.
(Note: Terminal support for combining characters is
auto-detected; additional command line options are available
in case this fails.)
If mined operates on a terminal that handles combining
characters, it offers two editing modes: combined or separated.
They can be toggled by clicking the Combining display flag
in the Mode indication flags area
(right part of the top screen line),
or by the menu entry "Options - Combined display";
separated display mode can also be selected by the
command line option -c.
Combined display and editing mode (Combining display flag ç)
Combined characters are displayed as intended (i.e., combined).
•
Micro movement into combined characters:
•
The cursor can be moved into a combined character with
Ctrl-cursor-left and Ctrl-cursor-right,
or ^V cursor-left and ^V cursor-right.
•
You can determine the exact position of the cursor if
permanent character info is switched on (by HOP ESC u or
with HOP "Toggle Char info" in the Options menu).
•
Partially editing combined characters:
•
If the cursor is on a combined character, delete next character
(e.g. Del on small keypad) will delete the whole
combined character, with all combining accents.
•
→NEW→
If the cursor is on a combined character, Ctrl-Del
will delete only the base character, leaving combining
accents which may then be combined with the previous
character.
•
If the cursor is within a combined character, delete next
character will delete the current combining accent only.
•
Ctrl-Backarrow or F5 Backarrow ("Delete single")
behind or within a combined character will only delete
the rightmost combining accent (preceding the cursor
position) while Backarrow would delete the whole
combined character.
•
You can also position the cursor as described above and use
copy-and-paste operations.
Note: Ctrl-cursor-left and Ctrl-cursor-right
only work if these keys are configured to emit
distinguished escape sequences with Control key held down.
With xterm, this works by default.
With rxvt, use the small keypad cursor keys, or enable Control
on the right keypad with the sample configuration
file Xdefaults.mined in the
Mined runtime support library.
With mlterm, enable this with the sample configuration
file mlterm_key in the
Mined runtime support library.
Ctrl-Backarrow can also be configured to work with xterm
but doesn't appear to work with rxvt or mlterm,
use F5 Backarrow instead.
Separated display and editing mode (Combining display flag `)
Combined characters are separated into base character and
combining character(s) for display and editing. Combining
characters are indicated with coloured background.
•
In separated display mode, all cursor and text modification
operations work on the combining parts as displayed.
Input support: For input of Unicode combining characters,
see Combining character input below.
Note: Unicode combining characters (according to the
most recent version of Unicode known to mined) that are not
handled as combining characters by the terminal (which might
implement an older version of Unicode)
are always displayed like in separated display mode.
Note: Isolated combining characters, i.e. those
appearing at a line beginning or after a TAB character, are
always displayed like in separated display mode.
Character information display
The command ESC u displays character encoding information in the
bottom status line (conforming to ISO 14755); it displays the
character code in the selected encoding (UTF-8 byte sequence
in UTF-8 mode) and the ISO-10646 (Unicode) value of the
current character, as well as Unicode script range and
character category, width, and combining information.
The Unicode value is displayed with 4 hexadecimal digits if
the character is in the Unicode BMP (Basic Multilingual Plane,
16 bit), with 6 digits if it is a Unicode character outside of
the BMP, and 8 digits if it is an ISO-10646 character outside
of the Unicode range.
The information displayed also indicates all kinds of
encoding irregularities.
For the Unicode data version used for character properties
see the mined change log.
Permanent display of character information is toggled
with HOP ESC u or by selecting "Char info" in the Info menu
(or with HOP "Toggle Char info" in the Options menu).
→NEW→
In the Info menu, attributes that are shown with the character
information can be selected:
Unicode script name, Unicode character name,
Unicode character decomposition, list of input mnemonics.
→NEW→
Character information display can be selected with the
+?c command line parameter (see
parameter description for further options).
To preselect continuous character information display, append
+?c to the environment variable MINED.
Han character information display
CJK-specific character information (semantic and pronuciation
hints) is described below in section
Han character information display.
Character conversion features
Case conversion
The case conversion functions (ESC C, HOP ESC C, F11, HOP F11,
Shift-F3) cover the full Unicode range.
They also handle special cases like Greek final sigma,
optionally Turkish "i", case mapping to multiple characters,
and Lithuanian special conditions.
Japanese characters are toggled between Hiragana and Katakana
by the same functions.
Shift-F3 cycles casing of a word between all small, title case
(beginning capital), and all capitals. It handles title casing,
using Unicode title case characters for the first character
when appropriate.
For Japanese script, it toggles the word between Hiragana and
Katakana.
The case mapping is based on the most recent Unicode
version compiled into mined (for the actual version see the
mined change log and the Options menu About command).
It is applicable in all text encodings.
Numeric conversion
Commands are available to insert characters corresponding to
a hexadecimal character code or hexadecimal/octal/decimal
Unicode value contained in the text, to insert a
respective value corresponding to the current character,
→NEW→ or
(Alt-x) to toggle the preceding character and its hexadecimal code.
For details, see the section
Code conversion in the Command reference.
Numeric entity (HTML/URL) conversion
→NEW→
HTML numeric character entities (e.g. &x40; for @) or
URL escape notation (e.g. %20 for space) can be converted into
unescaped characters. Use one of the
Mnemonic character substitution commands
(ESC _ or national variants) described below.
Mnemonic conversion
A character mnemonic at the cursor position can be replaced with
its associated character. Use one of the
Mnemonic character substitution commands
(ESC _ or national variants) described below.
Encoding conversion support
A special feature offers interactive conversion to or from
Unicode character encoding, see
Encoding conversion support in
chapter Unicode support below.
Unicode Copy/Paste buffer
The Copy/Paste buffer can be operated in Unicode mode in
which case it converts between text edited in different
character encodings.
See Unicode Copy/Paste buffer conversion
below.
Smart quotes
Straight (double or single) quote characters «"» or «'»
can be replaced automatically with an opening or closing
typographic quotation mark, depending on the text context.
Select the quotation marks style to be applied from the
Smart Quotes selection menu (open with ESC Q or Alt-Q or
right-click on the smart quotes indication in the flags area
in the top screen line), or middle-click on the smart quotes
flag to toggle between the current and the previous smart
quotes style selected with the menu.
When a file is loaded, mined tries to determine the applicable
quotation marks style in two ways: If mined edited the file
before and noted the last cursor position (in the file @mined.mar,
which can be created using the HOP F2 command, or the File menu
"Save Position" command), this information also includes the last
selected smart quotes mode for the file.
If that information is not available, mined auto-detects
existing quotation marks in the file and adjusts its smart
quotes mode accordingly.
The smart quotes left/right selection algorithm considers the
text context to automatically support smart quotes also in CJK text.
A typographic apostrophe can be inserted with HOP ' (^G ').
In smart quotes mode, straight quotes can be inserted with
mnemonic compose pairs (^V ^ " or ^V ^ ' , or ^V "# or ^V '#
respectively) or
→NEW→
with Alt-' or Alt-" (works in xterm 214/216 or later (with
modifyOtherKeys feature)).
Smart quotes are applicable in all text encodings provided
the desired quote marks are contained in the selected encoding.
Smart quotes style can also be preselected with the environment
variable MINEDQUOTES which should
then contain the opening/closing quote pair or just the
opening quote mark (UTF-8 encoded, double or single quotes);
this overrides both auto-detection and the preference saved
with the cursor position.
Smart text replacements: smart dashes and arrows
If smart quotes are active, some other smart input text
replacements are applied to sequently entered characters
(unless during a repeat command entering multiple characters):
\-\-
if preceded by a Space character: en dash (U+2013)
otherwise: em dash (U+2014)
-
if an adjacent character is in the Hebrew
script range:
Hebrew hyphen mark Maqaf (U+05BE)
<-
leftwards arrow (U+2190)
->
rightwards arrow (U+2192)
<>
left right arrow (U+2194)
Character input support
Some character input support features support international
scripts (especially with Keyboard Mapping and
Input Methods), others mainly address composite characters.
For the latter, it is useful to explain a few notions:
Combining character:
A character (usually in Unicode) that is defined to combine
with the previous character into a combined character, to be
displayed as a single glyph (visual unit).
Combined character:
The glyph combination of a Unicode character (base character)
with one or more Unicode combining characters.
Composed character (or composite character):
A character that has one or more accents composed
into it, or is otherwise composed of components, like the ae
ligature, to be displayed as a single glyph. It can be a
single Unicode character or a Unicode combined character
consisting of a Unicode base character and one or two Unicode
combining characters.
Accented character (or diacritic character):
A special case of a composite character where a letter is
composed with one or more accents.
Compose key:
A number of system and keyboard vendors have equipped
their keyboards with a "Compose" or "Combine" key. This key -
when configured and interpreted properly by the operating
environment - produces a composed character which is then
provided as input to the application.
Accented and mnemonic input support
Function keys or character mnemonics can be used to
enter accented or other composite characters.
(This is also known as digraph function with some editors.)
These character composition functions also work on the prompt line.
(Any composite character configured on your keyboard can of
course also be entered directly or using the Compose/Combine
key of your keyboard.)
→NEW→
Note that mnemonic input and accent prefix keys can be
combined in flexible ways, e.g.
^V ' Ctrl-F6 e
or
F6 ^V e ^
which both enter U+1EBF (e with circumflex and acute)
→NEW→
Mnemonic input can be applied recursively to compose a character
for further composition, e.g.
^V ' ^V a e
enters U+01FD (æ with acute)
→NEW→
Accent prefix keys can use an already precomposed base
character for further composition; if this does not match an
explicitly known mnemonic, the base character is decomposed
first to find a match, e.g.
F6 ü
or
F5 ú
which both enter U+01D8 (u with diaeresis and acute)
→NEW→
Up to three accent prefix keys can be combined by entering
them in sequence in order to compose characters with multiple
accents, e.g.
F5 F6 u
enters U+01D8 (u with diaeresis and acute)
Ctrl-2 Ctrl-7 a
enters U+1EB1 (a with grave and breve)
Ctrl\-\- Ctrl-: u
enters U+1E7B (u with macron and diaeresis)
Ctrl-, Ctrl-( e
enters U+1E1D (e with cedilla and breve)
Alt-7 Ctrl-, < alpha >
Alt-F6 Shift-F6 Ctrl-, < alpha >
Ctrl-< Ctrl-` Ctrl-, < alpha >
all enter U+1F82 (alpha with psili and varia and ypogegrammeni)
where < alpha > indicates the Greek letter
alpha, which may e.g. be entered by selecting the
Greek input method and typing the "a" key
Accent prefix keys
General notes on using keys with Control, Shift, Alt modifiers:
Especially for accented character input, mined makes use of
key combinations modified with Control, Shift, Alt, or a
combination of them.
Some of these key combinations may be limited by local
environment, especially the window system, or may need
extra configuration to be enabled.
•
Hint on input of Alt/Ctrl-modified function keys:
These are often intercepted by window systems for special
functions.
•
Alt: →NEW→
Alternatively to using the Alt key,
the ESC key can be used as a prefix to a function key to achieve
the same modified function, e.g. ESC F6 instead of Alt-F6.
Note, however, that there is an ESCAPE delay (default 450 ms)
during which the subsequent function key should be pressed.
•
Control: →NEW→
Alternatively to using the Control key,
Ctrl-V can be used as a prefix to a function key to achieve
the same modified function, e.g. Ctrl-V F6 instead of Ctrl-F6.
Specific advice:
Window system
suppresses
remedy
KDE
Ctrl-Fn, Ctrl-Shift-Fn, Alt-Fn
press the "Window key" additionally at the same time,
e.g. Window-Alt-F6 or use ESC or Ctrl-V prefixes,
e.g. ESC F6 (be fast!), Ctrl-V Shift-F5
Modified digit keys (e.g. Alt-2) as well as
→NEW→
Ctrl-modified punctuation keys (e.g. Ctrl-;)
are used as extended and intuitive accent prefix keys.
To enable them, either use a recent version of xterm (216) or
configure them with your terminal.
Configuration instructions for older versions of xterm and
for rxvt can be found in the sample file
Xdefaults.mined in the Mined
runtime support library.
•
Note: In rxvt, Ctrl-modified and shifted punctuation keys
(if enabled by configuration following the hint above)
interfere with ISO 14755 input mode of rxvt; if the following
key is entered twice, that mode is aborted and the modified
punctuation key becomes effective as an accent prefix in mined.
•
Warning: The Alt-F4 key combination should not
accidently be hit as many window managers use it to kill
the terminal window!
The following table lists the accent prefix keys:
F5
(Sun: R4/-)
diaeresis (umlaut) / dialytika

Note: If your keyboard assignment provides its own
accent prefix keys ("dead keys"), pressing the key twice usually
delivers the corresponding spacing character which can then be
used for the extended accent prefix functionality of mined;
e.g. hold Control, then press ´ (acute key) twice, to invoke
the acute/oxia prefix function of mined.
Note: For combining multiple accents, in most
cases their order does not matter. As an exception, to combine
dot above and macron, enter prefix keys in this order, as s
macron and dot above will be interpreted as dot below.
dot macron
e.g. Ctrl-. Ctrl\-\-
dot above and macron (on A or O)
macron dot
e.g. Ctrl\-\- Ctrl-.
dot below
Note: For the sake of accepting Ctrl\-\-
intuitively both as an accent prefix for macron as well as an
accent modifier to place an accent below a letter, the
macron accent prefix combined with another accent prefix key
is also interpreted as applying that accent below. As a
workaround to ambiguous cases, it has to be applied twice with
diaeris for diaeresis below (U), and three times for line below.
macron macron diaeresis
e.g. Ctrl\-\- Ctrl\-\- Ctrl-:
diaeresis below
macron diaeresis
e.g. Ctrl\-\- Ctrl-:
macron and diaeresis
diaeresis macron
e.g. Ctrl-: Ctrl\-\-
diaeresis and macron
macron macron macron
e.g. Ctrl\-\- Ctrl\-\- Ctrl\-\-
line below
Note: Some accent prefix keys, when applied twice in
sequence, are mapped to a single accent as follows:
acute acute
e.g. F6 F6
double acute accent
grave grave
e.g. Shift-F6 Shift-F6
double grave accent
macron macron
e.g. Ctrl\-\- Ctrl\-\-
bar/topbar
cedilla cedilla
e.g. Ctrl-, Ctrl-,
psili/comma below
Combining character input
Unicode combining characters can be entered
by applying accent prefix keys to the Tab key. They will be
visually combined with the previous character by rules of Unicode
(and by terminal implementation). Examples:
Ctrl-, Tab
combining cedilla
F6 F6 Tab
combining double acute accent
Special character input shortcuts
Typographic quotation marks can be entered
by applying accent prefix keys to the space key as follows,
or using certain input mnemonics or shifted combinations (see below):
(twice) grave space
(double) left quotation mark
(twice) acute space
(double) right quotation mark
acute space
e.g. F6 space
or Ctrl-' space
also serves for input of typographic apostrophe
(or HOP ')
(twice) cedilla space
(double) low-9 quotation mark
(twice) dot above space
(double) high-reversed-9 quotation mark
^V < < or ^V > >
double angle quotation marks « »
^V < space or ^V > space
single angle quotation marks
Alt-'
plain single quote mark (U+27)
Alt-"
plain double quote mark (U+22)
Some characters are specifically mapped to special key
combinations or specific applications of accent prefix keys
for convenience or for Windows compatibility:
Ctrl-Shift-space
no-break space (U+00A0)
Ctrl-@ a/A
å/Å
Ctrl-& a/A
æ/Æ
Ctrl-& o/O
oe/OE ligature
Ctrl-& s
ß
Ctrl-?
¿
Ctrl-!
¡
As with modified keys in general, these shortcuts may depend on
proper terminal configuration according to the sample files in
the Mined runtime support library.
Character input mnemonics
The enter-control-code prefix (^V, or ^Q in emacs mode, or ^P
in WordStar mode) can be used for mnemonic character composition.
This covers accented characters and other mnemonics.
The available mnemonics include RFC1345 mnemonics (extended
to provide generic accent mnemonics for Unicode characters),
mnemonics known from HTML and TeX and useful supplementary
mnemonics. See Character Mnemos reference
on the mined web site for a listing.
With mined 2000.10, supplementary character mnemonics have been
revised and made consistent with generic RFC1345 mnemonics,
redundant mnemonics have been removed, and coverage of all Latin
characters (esp. with multiple accents) has been completed.
For accent compositions, mnemonic patterns
(generic accent mnemonics) are listed in the following table;
the respective letter to place the accent(s) on is indicated
with an "x" below.
For Greek and Cyrillic accented characters, mnemonics combining
accents with Greek or Cyrillic base characters are generated
automatically from the UnicodeData.txt database.
Greek and Cyrillic accent prefix keys reuse those for
Latin accents and are listed in the sections on Greek and Cyrillic
script support (see Language support).

Two-letter mnemonics can also be entered in reverse order if
this is unambiguous.
Detection of reverse order mnemomics (two letters or one letter
and multiple accents) as well as the generic accent mnemonics
" ^ ` ~ ¨ ¯ ´ ¸ ° (which are available for
convenience in addition to the less intuitive > !
etc.) works with both short mnemonic entry (two-letter "^Vxy")
→NEW→ and full
mnemonic entry ("^V xy... ").
Mnemonic character substitution commands
(ESC _ and national variants) replace characters at the cursor
position with the respective character described by them.
The following substitute descriptions are detected:
•
Two-character mnemonic
•
HTML character mnemonic
•
HTML numeric character entity
•

Keyboard Mapping and Input Methods
Mined supports optional keyboard mapping which is especially
useful for Unicode or CJK editing.
When a keyboard mapping is selected, input characters or
sequences are transformed to other characters or sequences,
typically of a certain Unicode script range.
Keyboard mappings for Greek, Cyrillic, Hebrew, Arabic, and
major CJK input methods are preconfigured (they have been
ordered in the Input Method menu according to the order of
their respective basic ranges in the Unicode character set, or
to the order of the letters of the usual abbreviation CJKV for
East Asian text processing - Chinese, Japanese, Korean,
Vietnamese). The Radical/Stroke input
method provides additional functionality as a special case.
Mined provides compile-time configuration of additional input
methods; for this aim, further mappings can be generated using the
mkkbmap script (from tables
in various formats as used by other editors or
→NEW→
supplied by the m17n multilingualization package) and then
compiled into mined.
See Mined configuration below for details.
Keyboard mapping works as follows: You enter a key sequence
that is mapped to a character sequence in the selected
keyboard mapping table. The transformed character sequence is
used as input.
As some typical keyboard mappings contain ambigous key
sequences where one may be a prefix of another, a short delay
is applied in these cases to allow recognition of any such
sequence to be mapped. After a timeout, the shorter sequence
already matching will be used; the timeout can be cut short by
typing a Space key, the Space character itself will then be
discarded. (The timeout value is 900 ms by default and can be
configured with the environment variable MAPDELAY.)
Pick lists
Some keyboard mappings, especially for CJK input methods,
contain multiple choice mappings. In these cases, a selection
menu is displayed that offers a "pick list" to select a
character from. A character can be picked with a mouse click,
or by navigation to the desired choice with the cursor keys
(down/up, right/left, page down/up) or the '<'/'>' keys , or
by just selecting the menu row first (cursor-up/down), then
typing a digit 1-9 or 0 to select the numbered character.
The Space key can be configured to either navigate to the
next choice, the next row, or to select the current choice;
see option -K.
If the pick list is too large to fit on the screen,
the menu will be scrollable or pageable (using cursor keys).
While navigating through the pick list, the line and the
selected item in the line are highlighted accordingly; if
the current item is a CJK character, also its character
information (description and optionally pronunciations as
configured with the Han info option of
the '?' information flag menu) is displayed on the status
line. If the item is a word comprising multiple CJK characters,
the information for only the first of them is shown. The
available information is derived from the Unihan database.
Keyboard mapping data are based on Unicode. So in CJK text
mode, the selection menu (the pick list) may contain symbols
that are not mapped to the active CJK text encoding. In a
UTF-8 terminal, these will still be displayed but cannot be
inserted. In a CJK terminal, some characters may not be
displayed; an empty entry is shown instead. (In a non-Unicode,
when editing text in a different encoding, there may even
be characters that cannot be displayed in the selection menu
but can be inserted.)
Input method selection
An active and a standby input method (keyboard mapping) are
maintained. They can be toggled quickly for text input, also
on the prompt line.
The current mapping is indicated as the Input Method flag
by its two-letter script tag in the flags area, showing
"\-\-" if no mapping is active.
The active mapping can be selected in the following ways:
ESC k or Alt-k or Alt-F12 or left click on Input Method flag
toggles between current (active) and previously
selected (standby) input method (keyboard mapping)
(Alt- toggle functions also work on prompt line)
HOP ESC k (or HOP Alt-k)
clears input method, i.e. resets keyboard mapping
to none (unmapped input)
ESC I or Alt-I or ESC K or Alt-K or Ctrl-F12
opens the Input Method (Keyboard Mapping) selection menu
(Alt-I or Alt-K or Ctrl-F12 also work on prompt line)
right click on Input Method flag
opens the Input Method selection menu
HOP ESC K or HOP Alt-K
cycles through available input methods / keyboard mappings
Note: For preselecting the active or standby input method
by environment configuration, see about usage of the
environment variable MINEDKEYMAP below.
Note: Keyboard mapping is implicitly suppressed temporarily
where it is not useful: during mnemonic character input, HTML
marker input, command letter entry, help selection, yes/no prompting.
Character encoding support
A character encoding for interpretation and handling of text
is selected in one of the following ways:
•
One of the command line options -E...
with a number of options to specify the desired text encoding
(see the encoding options above).
•
From the Encoding Menu (one of the flag menus),
the encoding interpretation can be changed while editing;
to open it, click with the right mouse button on the encoding
indication in the flags area of the top line, or type Alt-E.
See also Mode indication flags for an overview.
To toggle between the current and the previously selected encoding,
click the Encoding flag with the left mouse button.
•
Auto-detection (by heuristic counting of valid character codes).
Note: The encodings to be taken into account for
auto-detection can be configured with the MINEDDETECT
environment variable. Set it to the desired list of single-letter
encoding indications to disable auto-detection of other encodings.
Recognised encoding indications are mentioned in the list of
auto-detected encodings below (they are the same as used with the
-E parameter).
UTF-8 auto-detection cannot be disabled this way.
•
Locale indication in environment variables
(see Locale configuration), especially
the variable TEXTLANG which does not affect the locale-related
assumption of terminal encoding.
Auto-detected character encodings
The following encodings are auto-detected unless
overridden with a -E command line
option (or -l or -u):
-
UTF-8
-
UTF-16 encoding (big or little endian) with or
→NEW→
without BOM (byte order marker)
8
any 8 bit encoding; this is auto-detected in a
generic way; the actual 8 bit encoding assumed
corresponds to the terminal encoding if it is an 8 bit
terminal; otherwise, Latin-1 is assumed;
using "8" in the environment variable MINEDDETECT
excludes all CJK encodings from auto-detection (but not UTF-8),
and adds all 8 bit encodings that are not included by default
L
Latin-1 (ISO 8859-1)
W
Windows Western ("ANSI", CP1252)
P
PC Latin-1 (CP850)
M
MacRoman
-
CJK encoding (with unspecified mapping) is
pre-auto-detected in a generic way; usually the actual
CJK encoding is determined, too
G
GB18030
B
Big5
J
EUC-JP
S
Shift-JIS
K
UHC
V
VISCII
CJK and mapped 8 bit encoding support
Mined supports major CJK encodings as well as mapped
8 bit encodings ("character sets").
Mined has built in support for a large number of 8 bit encodings
which appear to be in use or unique for a region. The Encoding
menu has been structured with sub-menus to provide a concise
menu selection feature.
Combining characters
In all character encodings handled by mined that contain
combining characters, mined handles them and provides partial
editing and an optional separated display mode as described
above in section Combining characters.
(CJK encodings EUC-JP, Shift-JIS and GB18030, Vietnamese TCVN and
Thai TIS-620, ISO Arabic, Mac Arabic, ISO Hebrew, Windows Hebrew).
Handling of combining text characters is properly coordinated
with the set of combining characters supported by the terminal.
For Japanese, the JIS characters that map to two Unicode
characters are supported.
Character code related commands
The command ESC u displays character encoding information in the
bottom status line (conforming to ISO 14755); this includes
the character code, the mapped Unicode character value,
script and character category, and combining information.
See Character information display for details.
With HOP ESC u, permanent display is toggled.
Other commands insert the code of the current character,
insert a character taking its character code or Unicode value
from the text,
→NEW→ or
toggle the preceding character and its hexadecimal code (Alt-x).
For details, see Code conversion in the
Command reference.
Terminal environment for CJK encoding support
Mined supports handling of CJK text encoding in any terminal
(see Terminal encoding support below).
However, proper display of a wide range of CJK characters can
obviously only work in either a Unicode terminal (recommended)
or in a native CJK terminal that runs the same encoding as the
selected text encoding.
CJK terminals:
For terminals that support native CJK encodings
(e.g. cxterm, kterm, hanterm), the terminal encoding assumed by
mined can be specified with a command line option or by proper
locale indication in one of the environment variables LC_ALL,
LC_CTYPE or LANG.
For available encodings, see Mode indication flags.
For usage of the +E options, see the
description of the Terminal
encoding options above.
For usage of the locale environment variables, see
Locale configuration.
Note: In native CJK terminals, it is often troublesome
to find a working encoding configuration and font setup, and
the locale environment is not automatically set by the terminals.
A collection of wrapper scripts is available
(
http://towo.net/mined/terminals.tar.gz) to help with this
setup problem and demonstrate the invocation of a number of
different CJK and 8 bit encoded terminal windows, along with
selection of suitable fonts and proper locale environment
setting.
Note: Native CJK terminals have a different
assumption of the range of character codes supported in an
encoding family, e.g. Big5 / Big5 with HKSCS, GB2312 / GBK /
GB18030, EUC-KR / UHC, EUC-JP without/with 3 byte codes.
For compact handling, mined always assumes the largest superset
of these encoding families. It does, however, have some features
to prevent display garbage in most cases when a terminal supports
a smaller character set:
By default, mined does not display the following CJK
character codes in a native CJK terminal, i.e. it displays a
substitute indication for them
(see CJK character display above):
•
Unknown characters: CJK characters that have no defined
mapping to a valid Unicode character.
Use the +C option to override this
display suppression and enforce transparent display of unknown
characters in a CJK terminal.
•
Invalid characters: CJK characters that do not match the
encoding scheme (e.g. wrt. to specified byte ranges) of the
selected encoding.
Use the +CC option to override this
display suppression and enforce transparent display of invalid
character codes in a CJK terminal.
•
Extended characters: CJK characters encoded with 3 or
4 bytes.
Use the +CCC option to override this
display suppression and enforce transparent display of extended
character codes in a CJK terminal.
Regardless of all these features and options, it may not
always be possible to prevent display garbage, especially
if the font used by the terminal does not cover the needed
character range.
To avoid these problems in general, it is recommended to use
a Unicode terminal for editing CJK encoded files.
See also Terminal interworking
problems for special hints about certain terminals.
Unicode support
Introduction: handling Unicode encodings
Mined interprets UTF-8 which is a multi-byte character
encoding of the ISO-10646 character set, part of which is also
known as Unicode.
When reading a file, it detects UTF-8 encoding automatically
(unless overridden by explicitly selecting a text encoding with
a command line option -u or
-l or -E...).
It can also edit UTF-16 encoded Unicode files (UTF-16 can
represent the complete 21 bit Unicode subset of ISO-10646).
UTF-16 big or little endian with or without BOM (byte order
mark U+FEFF) is auto-detected or can be selected with a
command-line option (see
notes under Locale configuration below).
UTF-16 is maintained transparently, i.e. a UTF-16 encoded file
is written back in UTF-16, and if it was beginning with a BOM
this is maintained.
No explicit UTF-16 entry exists, however, in the Encoding menu
since the text is internally handled in UTF-8. However, the
character encoding flag indicates UTF-16 file encoding with either
"16" (big endian) or
"61" (little endian).
UTF-8 internal representation, transparent handling of other text
Mined handles UTF-8 representation internally and also edits
and keeps illegal UTF-8 sequences. This way, if you
happen to open a Latin-1 or CJK or any other encoded file
in UTF-8 mode, or switch encoding while editing, or edit a
file with mixed encoding, the text contents can still be
edited and you will not loose any file contents information.
Character encoding indication
The upper-right flags area has a character encoding indication
which shows "U8" if UTF-8
text interpretation is selected. For Latin-1 text interpretation
"L1" is shown, for others see
Mode indication flags.
You may click on the indication flag to toggle between the
current and the previous selected encoding.
Character information display
The Character information display
command ESC u is described above; character information display
can also be preselected by environment configuration.
In UTF-8 mode, information shown includes the UTF-8 encoding
byte sequence.
Character input support
With ^V, mined's special character input support is invoked
(both while editing text and entering text on the prompt line,
e.g. as a search expression).
With this feature, (in addition to plain control characters)
a composite character can be entered by its accent combination
or other mnemonic character description;
a more-than-two letter character mnemonics would be embedded
in space characters after the ^V.
In addition, numeric character codes or values can be entered
with leading ^V#, octal/decimal with ^V##/^V#=, Unicode with
optional u/U/+.
(For examples, see description of the
^V function below.)
With numeric character input, mined supports successive
multiple character entry according to ISO 14755; if the
numeric code is terminated by a Space key, another numeric
character can be entered subsequently; an Enter key
terminates numeric character input.
See also the generic section
Character input support above
for input support for accented characters and keyboard mapping.
Encoding conversion support
Two functions support interactive character encoding conversion
(Latin-1 to UTF-8 or UTF-8
→NEW→ to current encoding)
to partially fix files with mixed encoding.
In either text encoding mode, the search function looks for
characters encoded in UTF-8 (when not editing in UTF-8 mode)
or not (when editing in UTF-8 mode); the command is
HOP ESC ( or Alt-F11 .
Then, convert the character with ESC _ or its national variant
(see mnemonic character substitution
commands in the Command reference).
For repeated interactive conversion, both functions can be
combined into Alt-Shift-F11 (convert current character, then
search next).
Unicode Copy/Paste buffer conversion
For the Copy/Paste buffer, Unicode mode can be selected which
maintains its contents always in Unicode, so that Copy/Paste
of text works between differently encoded files (or sections
of a file, if encoding is switched while editing) with automatic
character code conversion.
This mode is only effective while editing with non-Unicode
encoded text interpretation.
Select this mode with the command line option
-Eu or in the Paste buffer menu
(righ-click on the Buffer mode flag "=" or
"+") and select "Unicode".
Unicode buffer mode is indicated by cyan background of the
Paste buffer flag (then "=" or
"+"), except in Unicode text mode.
Smart quotes and dashes
If smart quotes mode is enabled (see the Quotes style menu under
the Quotes flag left to the Encoding flag and menu), quote mark
keys will enter typographic smart quotes instead. Smart dashes
also apply.
See Smart quotes above for more details.
Bidirectional terminal support
A bidirectional terminal (such as mlterm) will probably
also apply Arabic LAM/ALEF ligature joining. Mined auto-detects
this feature and enables bidi terminal handling automatically.
Otherwise, bidi terminal handling can be configured with the
option +UU.
In this mode, when displaying a menu, underlying text
lines that contain right-to-left characters are cleared first
in order to prevent display confusion between the terminal's
bidi algorithm and the menu position.
Also, with bidi terminal handling enabled, mined assumes
that the terminal applies Arabic LAM/ALEF ligature joining
and properly accounts for this feature in display position
handling.
In separated display mode, the joining part of the ligature
is indicated similar to the handling of combining characters.
Input support for right-to-left scripts (poor man's bidi mode)
This support feature for input of right-to-left text pieces
is enabled by default unless the terminal is detected to be
in bidi mode itself (e.g. mlterm).
"Poor man's bidi" mode is intended for quick entry of
right-to-left text without having a right-to-left terminal;
it is similar to the "revins" (reverse insert) option of vim
and works as follows:
After entering a right-to-left Unicode character, the cursor
position is moved left of it, so subsequent characters will be
appended left and the text shifted right. Characters are
stored in visual order while input support is implicit, based
on the characters being typed. Entering a left-to-right
character will automatically skip behind the previously
entered right-to-left text on the line (changed in mined 2000.10)
and switch to left-to-right direction; this behaviour
optimises inserting small pieces of right-to-left text into
basically left-to-right text; this priority is justified by
the assumption that this mode (with visual storing order) is
only useful for inserting small right-to-left quotations into
left-to-right text and not for editing right-to-left documents
(which should be stored in logical order).
Newline, Space, Tab, and combining characters attempt to
behave well according to what was entered before; however,
intermediate cursor movement is not considered.
Unicode line ends
Mined detects and handles Unicode line separators and
paragraph separators (unless disabled with
+u-u).
They are displayed as shown above.
→NEW→
Interpretation of these characters as line ends is disabled if
a file is explicitly opened in non-Unicode encoding (but not
if non-Unicode encoding is just auto-detected).
HOP Enter will insert a Unicode paragraph separator, Enter
in a line that already has a Unicode line end will insert a
Unicode line separator.
Also the keys Shift-Enter or Ctrl-Enter insert a paragraph
separator or line separator respectively.
Configuration: In order to enable shift and control
with the Enter keys, xterm or rxvt must be configured as shown
in the example configuration file Xdefaults.mined
in the Mined runtime support library.
Unicode display
In UTF-8 terminal mode, mined displays all Unicode characters
if they are contained in the font used by the terminal.
Fonts usually have a substitute glyph to indicate characters
not contained in the font.
Wide characters (double-width glyphs) are displayed in a
double-width character cell of the terminal.
Combining characters are displayed either combined or
separated (see Combining characters below).
Illegal UTF-8 sequences are displayed with highlighted
background, using the following indications.
Furthermore, control characters encoded as a UTF-8 sequence
and control characters in the "C1" range (values 0x80..0x9F)
will be displayed similar to normal control characters but
with coloured highlighting.
8
for an unexpected UTF-8 continuation byte (range 80-BF)
4
for a 0xFE (254) byte
5
for a 0xFF (255) byte
«
for a too short UTF-8 sequence if followed by a
single-byte character (00..7F)
»
for a too short UTF-8 sequence if followed by a
multi-byte character (C0..FF)
→NEW→
Illegal or non-Unicode characters are indicated with the following replacements:
�
(or ? or [])
a character code ending with FFFE or FFFF
(override substitution for transparent display with
+C)
�
(or ? or [])
a surrogate code point
(override substitution for transparent display with
+CC)
�
(or ? or [])
a code point outside the defined Unicode range
(override substitution for transparent display with
+CCC)
Character substitution display
Legal characters (in the effective text encoding) that cannot
be displayed in a non-Unicode terminal are indicated with the
following replacements:
¤ or
¤ (if wide)
a non-combining Unicode character that cannot be displayed
% or
% (if wide)(if the terminal cannot display ¤)
a non-combining Unicode character that cannot be displayed
` (or wide)
a Unicode combining character that cannot be displayed
E
the Euro character U+20AC
" or
' (or wide)
a double or single quotation mark character (typographic quote mark)
- or
~ or
= (or wide)
a dash or hyphen character
e, ê,
etc
→NEW→
a combined or other character that cannot be displayed which is based on
the displayed character by its Unicode decomposition
0 ..9 ,
A ..Z
etc
a corresponding fullwidth ASCII character
Configuration: Display colour of special or illegal
UTF-8 indications can be changed with the environment variable
MINEDUNI, the value should be the numeric part of an ANSI
terminal control sequence; optionally, the value can be
preceded by a character to be used for Unicode character
indication in non-Unicode terminal mode.
(The default configuration value is "¤ 46").
Combining and joining characters
Mined supports handling of combining characters,
featuring optional separate display and partial editing,
as described above in section Combining
characters.
Joining characters
If mined assumes that the terminal applies LAM/ALEF ligature
joining (either configured with the +UU
right-to-left display option or auto-detected), the joined
character width will be handled correctly in cooperation with
the terminal.
Mined supports ligature joining in both combining character
display modes:
•
In combined display mode, the screen position is accounted
properly.
→NEW→
Also, when deleting a character, a joined ligature is deleted
together with the base character, just like combining characters.
•
In separated display mode, the joining part of the ligature
is indicated using the appropriate isolated form, highlighted with
Unicode special indication background colour (similar to the
handling of combining characters).
Search expression limitations
Unicode search ranges can not be very large as all
included characters are listed in an internal buffer which is
limited to ca. 1 KB.
UTF-8 preservation and byte-transparent editing
When splitting lines that are too long for internal handling,
consistency of UTF-8 sequences is preserved (they are not split);
combining characters may get split off their base characters,
however, they will join seemlessly as lines are joined again
(e.g. when saving the file).
Note that combining characters at the beginning of a line are
not displayed in combined display mode.
Terminal environment
Unicode text can be edited in any terminal encoding (UTF-8,
8 bit, CJK), however, a UTF-8 terminal is preferable.
UTF-8 terminal operation can be configured in either of these ways:
•
Auto-detection: If the terminal emits cursor position reports,
mined can uniquely recognise UTF-8 terminal encoding and further
UTF-8 features
(see Terminal encoding support below).
•
Environment: By proper environment variable settings.
For more details, see Locale configuration.
Note: In general, it is advisable to start a
terminal window using a wrapper script that sets a suitable
locale environment at the same time, in order to support all
kinds of applications that are more dependent on proper
environment setting than mined is.
The mined installation also provides the script
uterm for this purpose, with its own manual page.
(In case uterm is not installed, it is also
included in the Mined runtime support library.)
•
Parameter: +EU selects UTF-8 terminal mode.
See also Terminal interworking
problems for special hints about certain terminals.
CJK support (Chinese/Japanese/Korean Han character features)
Mined provides CJK support features uniformly in Unicode
and in major CJK encodings. For information relating to
CJK character encoding see
Character encoding support below.
CJK input method support
Input methods for CJK characters are supported with
the keyboard mapping mechanism.
A number of popular input methods for CJK text input
are pre-configured, others can be added at compile-time
with the mkkbmap script.
Radical/Stroke input method
Mined provides a Radical/Stroke input method for CJK
characters with specific functionality in addition to keyboard
mapping; it works at two-levels, selecting a radical first,
then a character from a list sorted by stroke count.
If this input method is active, a selection menu for the 214
CJK radicals is displayed (without prior keyboard input).
The menu displays all variations of each radical. After
selecting a radical from this menu, a second-level menu
is displayed, showing all CJK characters based on the
selected radical, sorted by the number of strokes.
Many of these menus will not fit on the screen and can be
scrolled.
Pressing Escape here would return to the radical menu;
pressing Escape there would disable the input method.
To enter a non-mapped character (e.g. a line end), you
need to disable Radical/Stroke input method temporarily;
just toggle it back on with Alt-k (or Esc k) or Alt-F12 and
the radical menu will be displayed again for continued input.
For the Unicode version used as the character data source,
see the mined change log.
CJK character display
Combining characters (in both JIS encodings and GB18030)
are handled and the combined characters are displayed properly
in either combined or separated display mode in a UTF-8
terminal (like for UTF-8 encoded text).
The following special CJK character indications apply:
¤ or
¤
CJK character that cannot be displayed in the terminal
% or
%
(if the terminal cannot display ¤)
CJK character that cannot be displayed in the terminal
` or
`
CJK combining character that cannot be
displayed in the terminal
? or
?
CJK character code that has no known mapping to Unicode
(to enforce display on CJK terminal use option +C)
# or
#
invalid CJK character code that is outside of the
code range assigned to the encoding scheme
(to enforce display on CJK terminal use option +CC)
#
CJK character in extended code range
(esp. 3 and 4 byte codes, or codes with 0x80...0x9F
byte range) that cannot be displayed on CJK terminal
due to terminal capability limitations
(to enforce display on CJK terminal use option +CCC)
<
incomplete or otherwise illegal CJK code
Han character information display
When the cursor is on a Han character and either descriptive
or pronunciation information about this character is available
in the Unihan database (from unicode.org), mined can
optionally display this information, with a selection of
display details which may include semantic information and
various pronunciations.
To enable Han info, select it in the Info menu.
To open the Info menu, type Alt-F10 or right-click the
"?" flag.
The information can optionally be shown on the status line
(where it may be truncated if too long) or in a pop-up menu next
to the character.
Pronunciation information to be displayed can be selected
in the Info menu.
→NEW→
While selecting multiple pronunciation options, the menu stays open.
The same information is always shown while you are browsing
an input method pick list (then on the status line).
→NEW→
Han character information display can be selected with the
+?h command line parameter (or
+?x for short display on the
status line).
To preselect continuous Han character information display,
append this parameter to the environment variable MINED.
The information includes the character code (in CJK encoding,
both CJK code and corresponding Unicode value are shown).
The amount of descriptive information (from the Unihan
database) to be shown can also be preconfigured with the
environment variable MINEDHANINFO;
see Han info configuration below.
(For the Unicode version used for the Unihan data source,
see the mined change log.)
Terminal encoding support
Mined supports UTF-8 terminals, CJK terminals, Latin-1 and
other 8-bit encoded terminals.
Terminal feature detection
Mined performs auto-detection of a number of terminal
features:
•
For UTF-8 terminals, mined performs auto-detection of
terminal features (detection of UTF-8 terminal, different
width data and combining data versions, handling of
double-width, combining and joining characters).
•
For CJK terminals, mined performs some auto-detection of
specific CJK terminal features (handling of non-EUC code
points, handling of extended code range, GB18030, 3-byte and
4-byte encodings, detection of kterm JIS encoding, detection
of rxvt emulating CJK encoded terminal, special CJK width
properties, and terminal support of combining characters).
•
For mapped 8-bit terminals, mined performs auto-detection
of terminal support of combining characters.
•
For the Unicode version used for width and combining
character properties, see the mined change log.
•
CJK terminals cannot always be distinguished from 8-bit
terminals by auto-detection. Neither can the encoding of either
CJK or 8-bit terminals be auto-detected.
It is thus advisable to setup proper settings of locale
environment variables (LC_ALL, LC_CTYPE, LANG).
Alternatively, the effective terminal encoding can be indicated
to mined with a command line option (+EX).
For configuration details, see
Locale configuration below.
Specific terminal properties
For more specific configuration hints (especially for PC-based
terminals), and for description of the handling of certain
terminal interworking problems, see the
Terminal environment configuration
hints below.
Mined Command reference (command and key function assignments)
General note on using keys with Control, Shift, Alt modifiers:
Mined makes use of many key combinations modified with
Control, Shift, Alt, or a combination of them, as a resource
for invoking a larger number of specific functions, providing
modified functionality as well as accented character input
support.
Some of these key combinations may be limited by local
environment, especially the window system, or may need
extra configuration to be enabled.
Especially modified function keys are often intercepted by
window systems for special functions.
In general, mined interprets an ESC prefix as an alternative
for an Alt-key combination. For further advice and window system
specific hints on further remedies, as well as configuration hints,
to enable modified key input see the
hint box under Accent prefix keys above.

Accented character input support by accent prefix keys
Mined defines a number of function keys, modified function keys,
modifed digit keys, and →NEW→
modified punctuation keys for single and multiple accent
composition with a subsequently entered character; for a
detailed listing and description, see
Accent prefix function keys above.
→NEW→
Up to three accent prefix keys can be combined by entering
them in sequence in order to compose characters with multiple
accents.
These functions also work on the prompt line (e.g.
to enter search expressions).
F5 < character >
Compose character with diaeresis (umlaut accent),
e.g. a » ä
Shift-F5 < character >
Compose character with tilde,
e.g. a » ã
Ctrl-F5 < character >
Compose character with ring or with cedilla,
e.g. a » å , c » ç
Ctrl-Shift-F5 < character >
Compose character with ogonek.
Alt-Shift-F5 < character >
Compose character with breve.
F6 < character >
Compose character with acute accent (accent d'aigu),
e.g. a » á
Shift-F6 < character >
Compose character with grave accent,
e.g. a » à
Ctrl-F6 < character >
Compose character with circumflex accent,
e.g. a » â
Ctrl-Shift-F6 < character >
Compose character with macron.
Alt-Shift-F6 < character >
Compose character with dot above.
Ctrl-0 ... Ctrl-9
Compose character with accent, esp. for Vietnamese
accented characters.
(Ctrl-)Alt-1 ... (Ctrl-)Alt-5
Compose character with two accents, esp. for Vietnamese
double accented characters.
(Ctrl-)Alt-6 ... (Ctrl-)Alt-8
Compose character with two accents for Greek multiple
accented characters.
Ctrl-< punctuation key >
→NEW→
Compose character with accent (looking similar to the
modified punctuation character, e.g. Ctrl-, composes
with cedilla, Ctrl-: with diaeresis, Ctrl-minus
with macron, Ctrl-( with breve, Ctrl-< with caron,
Ctrl-/ with stroke, Ctrl-; with ogonek, etc; see
Accent prefix function keys
above for details).
Input support commands
Ctrl-V special input support
These functions also work on the prompt line (e.g.
to enter search expressions).
^V < control character >
Enter control character.
^V [ or ^V \ or ^V ]
Enter one of the control characters ^[, ^\, ^].
^V ^ ^ or ^V _ _
Enter one of the control characters ^^, ^_.
^V ^ ' or ^V ^ "
Enter one of the plain quote marks ' or "
(needed in smart quotes mode)
^V < accent > < character >
Compose accented character.
^V # xxxx < Space or Enter >
Enter character defined by a hexadecimal number being input
(depending on applicable encoding, byte value, Unicode
value, or valid CJK code is required).
^V # # xxxxxx < Space or Enter >
Like ^V # but using an octal number.
^V # = xxxxx < Space or Enter >
Like ^V # but using a decimal number.
^V # u or U or +
(followed by a numeric input as described above, with optional
# or = for octal or decimal input) interprets the input as a
numeric Unicode value which is converted into the current
text encoding.
^V # ... Space ...
With numeric character input, mined supports successive
multiple character entry according to ISO 14755 if the
numeric code is terminated by a Space key.
^V < function key >
This is not an input support function but rather the
function key is invoked as if pressed together with the
control key.
Mnemonic character input support
Mnemonics recognised include the following:
•
RFC 1345 mnemos (except mappings to Unicode private use areas);
in ambiguous cases, the RFC 1345 mnemos must be entered in
long mnemonic input mode, e.g. with "^V pi " rather than "^Vpi".
•
HTML mnemos; in ambiguous cases, the HTML mnemos
must be prepended with a "&".
•
TeX mnemos (macros) and substitutes, leaving out any "\".
•
Supplementary mnemos as listed on the
mined character mnemos page.
Unless there is an ambiguous mapping, all two-letter mnemonics
can also be entered in reverse order.
^V < Space > < name > < Space or Enter >
Lookup character mnemonic and enter character. RFC 1345
mnemonics take precedence in ambiguous cases.
^V < character > < character >
Compose two characters. Non-RFC 1345 mnemonics take
precedence in ambiguous cases.
Note:
→NEW→
A number of mnemonics are defined with already precomposed base
characters (especially for Vietnamese input) which can be used
for further composition.
^V can be applied recursively to compose a character
for further composition.
See examples with æ below for both cases.
Examples:
^V^A
Enter Ctrl-A.
^V^[ or ^V[
Enter the escape character.
^V__
Enter Ctrl-_.
^V'e
Enter é (e with accent d'aigu).
^Vae
Enter æ (the ae ligature).
^V ae' (terminated by Space or Enter)
Enter U+01FD (æ with acute).
^Væ'
Enter U+01FD (æ with acute).
^V ^Vae' (terminated by Space or Enter)
Enter U+01FD (æ with acute).
^V'^Vae
Enter U+01FD (æ with acute).
^VOK or ^Vcm
Enter the check mark ✓ (U+2713)
^Vzz or ^V zigzag (terminated by Space or Enter)
Enter the downwards zigzag arrow ↯ (U+21AF)
^V-,
Enter ¬ (the negation symbol).
^V neg (terminated by Space or Enter)
Enter ¬ (the negation symbol).

Enter the Euro character (which has the hexadecimal
Unicode value 20AC) encoded in the currently selected
text encoding.
^V#+20ac < Space > +20ac < Enter >
Enter two Euro characters in
successive multiple character entry mode (ISO 14755).
Input method (Keyboard mapping) selection
ESC k or Alt-F12 or middle click on Input Method flag (mapping indication in flags area)
toggles between current and previously selected input method
(or initially the configured standby input method)
Note: (Alt-k or Alt-F12 also works on prompt line)
HOP ESC k
clears input method, i.e. resets keyboard mapping to none (unmapped input)
ESC I or ESC K or Ctrl-F12 or right click on Input Method flag (mapping indication in flags area)
opens the Input Method selection menu
Note: (Alt-I or Alt-K or Ctrl-F12 also works on prompt line)
HOP ESC K
cycles through available keyboard mappings / input methods
Modifying text
Note on character deletion
In order to accommodate various common ways of assigning
control character codes to the Del and Backarrow keyboard keys,
mined adjusts its own function assignment to the environment
setting of the terminal interface, see
Automatic backspace mode adaptation.
(The ASCII DEL control character can be enforced to delete
a character left with the option -B.)
Note on the Del key
Many people expect the "Home" and "End" keys to move the
cursor to the beginning or end of line, respectively, and the
"Del" key to delete the next character.
In the keyboard usage approach of mined, this is a waste of
keyboard resources as these functions can easily and quite
intuitively be invoked with "HOP left" and "HOP right", i.e.
by pressing the keypad keys "5 4" or "5 6" in sequence, and
all these keys are available twice on typical keyboards.
So there is enough room left for mapping the most
frequent paste-buffer functions to the keypad as described
above which is considered much more useful.
Use Alt-Del (or ESC Del, or Ctrl-Del) to delete the next
character, or use the -k option to
switch keypad key function assignments for the Home, End, and
Del keys.
See Keypad layout above for a
motivating overview of the mined keypad assignment features
and options.
Backarrow or ^H
Delete character left.
If there is only blank space before the current position in
the current line and the line above, the auto-undent function
(Back-Tab) is performed instead, deleting multiple spaces back to
the previous level of indentation.
Note: Mined tries to map this function to the
Backarrow key on the keyboard whether it is assigned to
the Backspace or DEL control characters, see note above.
Ctrl-Backarrow (if key properly configured) or F5 Backarrow
"Delete single": Delete only right-most combining accent
of combined character left of cursor position.
If not next to a combined character: delete character left,
avoiding auto-undent function.
Del (on numeric keypad)
Cut selected area to paste buffer.
Del (on small keypad, if properly configured to be distinguished)
Delete character right, including any combining characters.
→NEW→
Ctrl-Del (both keypads, if key properly configured)
Delete character right, excluding any combining characters.
Shift-Del (if key properly configured)
Cut selected area to paste buffer.
HOP Backarrow
Delete beginning of line (left of current position).
^B
Delete character right (next character).
^T
Delete next word.
^^ (overridden when used as accent prefix, e.g. with newer xterm)
Delete previous word.
^K
Delete tail of line (from current position to line-end);
if at end of line, delete line end (joining lines).
HOP ^K
Delete whole line.
Code conversion
ESC X
Insert hexadecimal representation of current character code.
(In UTF-8 mode, this is the UTF-8 byte sequence
of the character in hexadecimal notation.)
... with HOP:
Insert character with hexadecimal code
scanned from text at current position.
ESC U
Insert (hexadecimal) Unicode value of current character
(with either 4/6/8 hexadecimal digits, depending on the
value); in CJK or mapped 8 bit encoding mode, the
value is transformed from the current text encoding
into Unicode.
... with HOP or Ctrl-Shift-F11
Insert character with hexadecimal Unicode value
scanned from text at current position; in CJK or
mapped 8 bit encoding mode, the value is transformed
from Unicode into the current text encoding.
ESC A
Like ESC U but inserting an octal Unicode value.
... with HOP:
Like HOP ESC U but scanning an octal Unicode value.
ESC D
Like ESC U but inserting a decimal Unicode value.
... with HOP:
Like HOP ESC U but scanning a decimal Unicode value.
Alt-x
→NEW→
Toggle the preceding character and its hexadecimal code.
The command detects a 2 to 6 hex digit character code with
a valid Unicode value, or a non-digit Unicode character,
respectively.
Case conversion
ESC C or F11
Exchange case (low/capital) of character under cursor.
Case mapping is based on Unicode (but applicable in
all text encodings).
Special handling is applied for:
Greek final s, Turkish "i" if the effective locale
environment variable (LC_ALL, LC_CTYPE, LANG) begins
with "tr" or "az", case mappings to multiple
characters, Lithuanian special conditions.
Japanese characters are toggled between Hiragana and Katakana.
... with HOP or Shift-F11
Apply case conversion to word from cursor.
Shift-F3
Cycle casing of a word between all small, title case,
and all capitals (title case means the first letter is either
capital or actually a Unicode title case, the following letters
are small). For Japanese script, it toggles the word between
Hiragana and Katakana.
Mnemonic and special conversion
ESC _ or Ctrl-F11
Mnemonic character substitution replaces the two characters
at the cursor position with a suitable composite
character (e.g. accented character) if possible.
With Ctrl-F11, transformations are the same as with
the ^V two-letter character input mnemonics.
With ESC _, language-dependent preferences may take
precedence (see variations below)
according to the current locale environment.
Example: ae->æ
Special conversion features
•
If the text at the cursor position contains an HTML
character tag (starting with "&" and optionally
ending with ";"), it is replaced with the actual
character it represents.
Example: &not;->¬
•
→NEW→
If the text at the cursor position contains an
HTML numeric character entity (starting with "&#"
and optionally ending with ";"), it is replaced with
the respective character it denotes.
Example: @->@
@->@
•
→NEW→
If the text at the cursor position contains a URL
numeric escape notation (starting with "%") it is
replaced with the actual character it represents.
Example: %40->@
•
The command also transforms between Latin-1 and UTF-8
encoded characters if an accordingly encoded character
is found at the current position; the current
character encoding mode is used to determine the
target character set.
Example: æ (Latin-1 encoding)->æ (current UTF-8 encoding) or
æ (UTF-8 encoding)->æ (current encoding)
As variations of ESC _, there are some commands ESC LETTER
using national letters that occur on respective national keyboards.
They apply basically the same transformations but with
some national preferences taking precedence:
ESC ä or ESC ö or ESC ü or ESC ß
Similar to ESC _, but with German transformation preferences.
example: ae->ä, oe->ö
ESC é or ESC è or ESC à or ESC ù or ESC ç
Similar to ESC _, but with French transformation preferences.
example: oe->œ (oe ligature U+0153)
ESC æ or ESC å or ESC ø
Similar to ESC _, but with Danish transformation preferences.
example: ae->æ, oe->ø
Encoding conversion
HOP ESC ( or Alt-F11
Search for a character encoded in the "wrong encoding",
i.e. a UTF-8 character in non-UTF-8 text mode, or a Latin-1
character in UTF-8 text mode.
ESC _ or ESC ö etc.
If invoked on a non-ASCII character,
UTF-8 / →NEW→ non-UTF-8
character encoding conversion is applied:
If the character is not encoded in the current text encoding
it is converted into the current text encoding (from UTF-8 or
from Latin-1).
Alt-Shift-F11
Convert Latin-1 / UTF-8, then search for the next
"wrong encoded" character.
Paragraph formatting
ESC j
("Clever Justify") Format paragraph by word-wrapping
according to the currently set right margin value;
left margins are derived from the contents of the
paragraph and line. Heuristic detection of numbered
items automatically triggers appropriate indentation.
End-of-paragraph is a line without trailing blank space.
... with HOP:
Same, but end-of-paragraph is considered to be a blank line.
ESC J
("Normal Justify") Format paragraph by word-wrapping
according to the currently set left and right margin values.
End-of-paragraph is a line without trailing blank space.
... with HOP:
Same, but end-of-paragraph is a blank line.
ESC <
Set left margin for justification.
ESC ;
Set left margin of first line of paragraph only.
ESC :
Set left margin of next lines of paragraph only.
ESC >
Set right margin for justification.
HTML support
ESC H (every first time)
Enter HTML tag (and remember for subsequent ESC H).
(Note that Alt-Shift-H will do the same thing if your terminal
is configured appropriately - see the example configuration file
Xdefaults.mined in the
Mined runtime support library.)
The tag can be entered with attributes and values; these
will not be repeated in the closing tag (see next entry
on ESC H).
ESC H (every second time)
Enter closing HTML tag.
Any tag attributes and values entered with the tag (see previous
entry on ESC H) will be left out.
HOP ESC H
Put text between mark and current position in HTML tags.
The "A" tag gets special treatment.
Text block and buffer operations
Note on the Home, End, and Del keys
Many people expect the "Home" and "End" keys to move the
cursor to the beginning or end of line, respectively, and the
"Del" key to delete the next character.
In the keyboard usage approach of mined, this is a waste of
keyboard resources as these functions can easily and quite
intuitively be invoked with "HOP left" and "HOP right", i.e.
by pressing the keypad keys "5 4" or "5 6" in sequence, and
all these keys are available twice on typical keyboards.
So there is enough room left for mapping the most frequent
paste-buffer functions to the keypad as described above which
is considered much more useful.
Use Alt- (or Ctrl-) with the Home, End, or Del keys
for the line positioning and character deletion functions,
depending on terminal support and configuration;
or use the -k option to switch
keypad key function assignments for the Home, End, and Del keys.
See Keypad layout above for a
motivating overview of the mined keypad assignment features
and options.
^@ (Ctrl-Space)
or Home (on right keypad) or Shift-Home
or ^] or ESC @ or ESC ^
or Stop (sun)or Select (vt100)
Set mark (to remember the current location).
... with HOP:
Goto mark.
^Y
or End (on right keypad) or Shift-End
or Copy (sun) or Do (vt100)
Copy selected text (between mark and current position)
to paste buffer.
... with HOP:
Append to buffer.
^U
or Del (on right keypad) or Shift-Del
or Cut (sun) or Remove (vt100)
Cut selected text (between mark and current position)
to paste buffer.
... with HOP:
Append to buffer.
^P or Ins or Ctrl-Ins
or Paste (sun) or InsertHere (vt100)
Paste contents of buffer to current position.
With ^P or Ctrl-Ins, the cursor is placed before the
pasted region.
With Ins, the cursor is placed behind the pasted region
unless the option -V was used.
In rxvt, with Ins on the left keypad, the cursor is placed
before (left of) the pasted region.
... with HOP: (e.g. HOP Ins or ^G^P)
Paste from inter-window buffer.
Thus you can quickly copy text from one invocation
of mined to another.
Alt-Ins or Ctrl-F4
Replace text just pasted with preceding paste buffer.
This command uses a ring of paste buffers (like emacs "yank ring").
^G N m or ESC g N ,
(N=0..9) Set marker N. (^G N , also works.)
ESC m N
(N=0..9) Set marker N.
^G N ' or ESC g N '
(N=0..9) Go to marker N. (^G N g or ^G N . also works.)
ESC ' N (deprecated)
(N=0..9) Go to marker N.
ESC b or Shift-F4
Copy contents of paste buffer into a file.
... with HOP:
Append to file.
ESC i or F4
Insert file at current position.
Print from File menu
Print text being edited (to default printer).
HOP ESC ! or (deprecated) ESC c
Invoke operating system command (prompted for) with paste buffer as input.
Search
Note on case-insensitive searching
→NEW→
Mined applies case-insensitive search pattern matching where
the search pattern contains small characters, unless when
searching for an identifier (current identifier occurence, HOP
F8, or identifier definition, Alt-t). For a case-sensitive
search for a small letter, use a single-letter range
expression like [x] or a backslash escape
like \x (note, however, that \n and
\r have special meaning).
ESC / or Find or F7 or F8
Search forward (prompt for regular expression).
... with HOP:
Search for current identifier.
ESC \ or Alt-F7 or Alt-F8
Search backward (prompt for regular expression).
HOP F8 or Shift-F9
Search for current identifier.
HOP Alt-F8 or Alt-Shift-F9
Search for current identifier backward.
HOP Shift-F8 or ESC t or Alt-t
Search for definition of current identifier (using tags file).
See ESC t below for further description.
HOP Ctrl-Shift-F8
Search for identifier definition (prompts for identifier).
HOP Ctrl-F8 or Ctrl-Shift-F9
Search for current character.
^N or F9
Search for next occurence (using previous
search expression and direction).
... with HOP:
Repeat last but one search; two alternating
search expressions can be used with this command.
Alt-F9
Search again (for last expression) but in the opposite
direction.
ESC , or Shift-F8
(Global) Substitute (prompt for search and replacement strings).
ESC r or Ctrl-F8
(Global) Replace with confirmation prompting (first prompt
for strings).
ESC R or Ctrl-Shift-F8
(Line Replace) Substitute on current line (prompt for strings).
ESC ( or ESC ) or ESC { or ESC }
Perform one of the following matching searches, depending on text:
Search for corresponding bracket matching the bracket
at current position in one of the pairs (), [], {}, <>, «».
(Nested matching bracket pairs are skipped.)
In an HTML or XML file, search for matching tag (nesting considered).
Search for matching /* */ comment delimiter.
Search for matching #if #else/#elif #endif structures
(nesting considered).
On an #else or #elif directive, the search direction depends
on the command character, i.e. ESC ( searches backward, ESC )
searches forward.
In a mailbox file, on any mail header line, search for
next or previous mail message, depending on the command character,
i.e. ESC ( searches backward, ESC ) searches forward.
In a mailbox file or saved mail message, on a MIME separator,
search for next or previous MIME separator, depending on the
command character, i.e. ESC ( searches backward, ESC ) searches forward.
ESC t or HOP Shift-F8
Search for and move to the location of the definition of
identifier at the current cursor position. This command
uses the tags file that can be generated with the
ctags command (Unix).
It opens another file if necessary and automatically saves
the current file then.
Like with a number of positioning commands, ESC t places
the current position on the position marker stack before going
to the location of the identifier definition. The command ESC
Enter (Alt-Enter) can move back to that position, even if
edited files were changed with the command.
HOP ESC t
Similar, but prompts for identifier.
HOP ESC ( or Alt-F11
Search for a character encoded in the "wrong encoding",
i.e. a UTF-8 character in Latin-1 mode, or a Latin-1 character
in UTF-8 mode.
Special functions in a search string
matches any character.
^
(at begin of pattern) restricts match to the begin of a line.
$
(at end of pattern) restricts match to the end of a line.
[< character set >]
matches any one of a set of characters;
the set may be given by listing elements,
denoting a range < c1 >...< c2 >,
or negating the whole set [^< character set >].
\< character >
matches the character literally (except n or r).
< pattern >*
(a star appended to any one of the defined patterns)
matches a (zero or more times) repetition of this pattern.
In a final position within the search expression,
however, it matches one or more times this pattern.
^V^J or \n
(a linefeed character or its representation)
searches for newline embedded in the search pattern
→NEW→ \r
searches for DOS/Windows newline (CRLF) embedded
in the search pattern
Special functions in a replacement string
&
is replaced by the matched pattern to be replaced.
^V^J or \n
(a linefeed character) embeds a newline
(LF character) in the replacement string
\r
(a carriage return character) embeds a CR
character in the replacement string
File operations
ESC w or F2
Save (write back) current text to file (only if modified).
... with HOP:
saves current file position in marker file
@mined.mar, so that subsequent editing sessions will start
at the current position and remember formatting parameters.
ESC W or Shift-F2
Save (write back) current text to file (unconditionally).
Alt-F2
Save As; save current text to file with different name;
→NEW→
file permissions (access modes) are preserved and cloned.
Ctrl-Shift-F2 or HOP Shift-F2
Save to file, and enable memory for file positions in
current directory; current file positions will always be saved
in marker file @mined.mar so that subsequent editing sessions
will start at the current position and remember formatting
parameters.
F3
Edit another file (prompt for save if current text changed).
Ctrl-F3 or ESC v
View another file (prompt for save if current text changed).
ESC V

ESC ESC or Ctrl-F2
Exit editing current text (save first if changed), continue
with next file if multiple files are being edited,
otherwise exit mined.
Note: There is a small delay after typing ESC ESC.
(This is in order to enable recognition of Alt-function key
combinations which are implemented by some terminals or
terminal modes by prefixing ESC to the function key escape
sequence.) This delay can be avoided by using Ctrl-F2.
ESC +
Edit the next file in the list of files being edited.
... with HOP:
Edit the last file in the list.

Note: If the function to be repeated is a character
to be inserted and the input is keyboard mapped to a
multi-character sequence, only the first character of the
sequence is inserted repeatedly.
ESC < count >
Repeat a command < count > times (prompts for rest of count);
this short form is only accepted, however, if the repeat count
consists of at least two digits (this is to avoid confusion with
function key escape sequences of certain terminals).
Example: ESC77. enters a line of 77 dots,
ESC07x enters "xxxxxxx".
^V < function key >
Invoke function as if pressed together with the control key.
E.g. ^V < cursor-left > moves left into the parts of a
combined character just like Ctrl-cursor-left would do
(the latter may depend on proper terminal setup).
^\
Abort current command, e.g. while on prompt line.
ESC ?
Show the current status of the file (name, whether modified,
current line, number of lines, characters, and bytes).
... with HOP:
Toggle permanent display of text status line.
Note that when editing a file that does not fit completely in
memory (e.g. large file on old system), this option may cause
considerable swapping. In that case, do not use the feature.
ESC u
Display the character code of the current character
in the bottom status line.
(In UTF-8 encoded text mode, both the UTF-8 byte
sequence and the Unicode value are displayed; in CJK
or mapped 8 bit encoded text mode, Han or 8 bit
character values and corresponding Unicode values are
displayed when applicable.)
In non-Latin-1 encoded text mode, additional Unicode
information is included, indicating the script,
character category, width, combining, and surrogate
properties of the character.
... with HOP:
Toggle permanent character code display.
ESC T
Toggle Tab width.
Alternates the width interpretation of Tab characters
between 4 and 8.
... with HOP:
Toggle Tab expansion (input substitution with spaces).
ESC P
Set page length (number of lines that mined assumes to
be on a page). (Useful for status display.)
ESC a
Toggle append mode (append to text buffer/file instead of
overwriting).
ESC d
Show current directory / change to another one
(also change drive in MSDOS version).
The assumed (relative) file path name
→NEW→
as well as file permissions (access modes) are preserved.
ESC n or Set Name... from File menu
Change the file name associated with the text being edited;
the file is not actually saved yet but only the new
file name is used for saving the next time.
The text is detached from the file previously loaded
which is not affected.
All current text editing properties (assumed
encoding, smart quotes style, margins, ...)
→NEW→
as well as file permissions (access modes) are preserved.
ESC .
Redraw the screen.
ESC l
Make screen lower (decrease number of screen lines).
ESC L
Make screen higher (increase number of screen lines).
ESC %
Make screen smaller (decrease screen size).
ESC &
Make screen bigger (increase screen size).
ESC z
Suspend editor process; first write back file if modified
(no write if HOPped or given empty file name on prompting).
ESC !
Fork off a shell and wait for it to finish.
... with HOP:
Invoke operating system command (prompted for) with paste buffer as input.
F1 or Help or Alt-h or ESC h
Online help function.
Selection of help topics is offered and prompted;
after entering the initial letter, the respective
help section is shown.
If another (modified) F1 key, a modified digit key,
or a Ctrl-modified punctuation key is entered,
a corresponding key assignment help bar is displayed
(see F1 F1 etc. below).
The online help file mined.hlp is
installed with the
Mined runtime support library. If
this is not installed in one of the standard
locations, the environment variable MINEDDIR should be
set to point to the directory so mined can find its
online help file.
... with HOP:
If followed by a topic selection (initial letter after
prompt), view online help with mined (in read-only
mode) by opening the online help file (instead of
invoking the "less" viewer) and positioning to the
selected help topic.
Before opening the help file, the text being
edited is automatically saved (if it was modified) and
any prompting required will be performed. The
suspended editing session will automatically be
restored after help viewing is finished.
F1 F1 or Shift-F1 or Ctrl-F1 or Alt-F1 or Ctrl-Shift-F1 or Alt-Shift-F1
Display a help bar (in the bottom status line) with short
indications of the functions assigned to the function keys
F2... in the corresponding modified mode (i.e. with Control,
Shift, and Alt as requested for the help bar).
... with HOP:
Toggle permanent help bar display.
F1 Ctrl-1 or F1 Alt-1 or F1 Alt-Ctrl-1
→NEW→
Display a help bar (in the bottom status line) with short
indications of the accent prefix functions assigned to the
digit keys 1..9, 0 in the corresponding modified mode
(i.e. with Control and Alt as requested for the help bar).
... with HOP:
Toggle permanent help bar display.
F1 Ctrl-< punctuation key > e.g. F1 Ctrl-,
→NEW→
Display a help bar (in the bottom status line) with short
indications of the accent prefix functions assigned to the
Ctrl-modified punctuation keys.
... with HOP:
Toggle permanent help bar display.
ESC
While a command is active and prompting (e.g. for a search
expression), ESC aborts the current command.
ESC Space
Do nothing, so the Space key aborts the ESC command.
MSDOS only
Ctrl-Alt-Space
Set mark (to remember the current location).
F1 or ESC h
If followed by a topic selection (initial letter after prompt),
view online help with mined (like HOP F1).
Screen size change functions
MSDOS screen size changes depend on a
mode table contained in the source file keydefs.c.
In the presence of a TSR driver which can change
fonts and screen modes while running a program
(e.g. the excellent VGAMAX), the actual change
effective may occasionally be unexpected. Mined does
however recognise those changes and adjusts its
conception of screen size appropriately, although
only after the next character being input.
Alt\-\- (on keypad)
Change video lines mode to the mode with the next smaller
number of lines but same number of columns.
(The number of lines is first tried to be decreased
within the current video mode. If it is already
the lowest, the next video mode is chosen.)
Alt-+ (on keypad)
Change video lines mode to the mode with the next higher
number of lines but same number of columns.
Ctrl\-\- (on keypad)
Change video mode to the mode with the next smaller
total resolution (lines * columns).
Ctrl-+ (on keypad)
Change video mode to the mode with the next higher
total resolution.
Alt-/ (on keypad)
Switch between highest and lowest line number modes
within the current basic screen mode.
Ctrl-/ (on keypad)
Cycle through all line number modes
within the current basic screen mode.
HOP Ctrl-/Alt- +/- (on keypad)
Several other video mode settings are prompted for
(experimental).
emacs mode
Mined emulates emacs keyboard layout and some specific functions if
invoked with the option -e or with the
command name alias minmacs.
In emacs mode, emacs command key assignments to control keys,
ESC (Meta commands) and ^X (C-X commands) are configured.
In addition, the following emacs-compatible changes apply:
•
The mined ESC commands can be reached via M-x.
(Function keys remain unaffected.)
•
The Del key (on the small keypad) is configured to
delete the previous character.
•
The control key insertion prefix is ^Q.
•
The quit character (e.g. for the prompt line) is ^G.
•
The emacs multiple buffer ring is fully enabled.
•
Paragraph justification mode is set to consider an empty line
as paragraph separation by default.
•
Mined ESC commands can be reached via M-x (Alt-X).
•
^\ (Ctrl-\) is interpreted as an additional HOP key.
•
Keyboard mapping (input method) can be toggled with Alt-F12

Terminal environment
The Unix terminal type is determined from the environment
variable TERM.
Recognition of some special terminal features or restrictions
is associated with the setting of TERM (xterm, linux, vt100,
sun*, cygwin, rxvt, *ansi*, 9780*,
hp*, xterm-hp, superbee*, sb*, microb*,
scoansi*, xterm-sco, cons*, att605-pc, ti_ansi, mgterm).
Non-trivial screen features (like scroll reverse, add/delete line,
erase multiple characters) are used if their support is indicated
in the termcap/terminfo description of the terminal unless other
information is available (e.g. after terminal version detection,
an older xterm is supposed not to support erase characters).
Since colour support is often not configured within terminfo but
modern terminals do support it, mined always tries to apply
colour attributes (if the terminal at least supports ANSI
control sequences). A number of other "best practice" approaches
are taken to optimize the usage of terminal capabilities, esp.
covering different methods of graphics display support (for
menu borders).
For detection of function keys and cursor keys,
the escape sequences being used by terminals are often
not known to an operating system environment because they
are poorly and incompletely configured. Because this does
usually not work as expected (see this
bug report just for an example), mined does not rely on
the termcap/terminfo configuration of function key codes alone
(which it considers however since mined 2000.14);
rather it always accepts a wide variety of typical codes.
A few ambiguous codes are resolved according to the TERM
variable.
In an xterm, window headline and icon text are set to the
current filename and "(*)" is added if the text has been
modified.
Locale configuration
The locale mechanism as implemented on modern systems has a
number of design problems, one being that there is
no explicit distinction between text encoding and terminal
encoding although this is obviously a very different thing and
mixed combinations of both may occur and are actually supported
by mined.
For this reason, mined extends the locale environment variable
mechanism with the variable TEXTLANG which is only considered
for assumed text encoding (with precedence over the other
locale variables).
Also mined provides additional features to specify both
terminal and text encodings.
•
For text encoding, mined checks the variables
TEXTLANG, LC_ALL, LC_CTYPE, LANG in this order.
•
For terminal encoding, mined checks the variables
LC_ALL, LC_CTYPE, LANG in this order.
•
Explicit command line parameters are available to specify
either terminal encoding (+E)
or text encoding (-E). They override
environment variable settings.
•
UTF-8 terminal auto-detection overrides other terminal
encoding settings.
•
Text encoding auto-detection overrides environment
settings but not command line settings.
•
Assumed text encoding can be switched while editing.
For encoding recognition from locale environment variables,
mined recognises locale specifications typically found in
system installations, including those which do not include an
explicit encoding suffix. Known character encoding suffixes
("codeset" component of locale name, starting with ".") are
recognised regardless of whether the given locale is installed
or not. Other encodings are recognised by region suffix
(starting with "_") or full locale name or alias.
In addition to hard-coded locale recognition (especially for CJK),
locale values and associated encodings are configured in the
compile-time configuration file locales.cfg which
especially lists locale names that do not have an explicit
encoding suffix.
You can use these settings (known locale name or generic
locale name suffix) even on legacy systems without locale
support to indicate the terminal environment properly to mined.
For encoding recognition from command-line parameters,
mined provides three options:
•
-EX or +EX
with a single-letter encoding tag as listed with the description
of the
-E options;
further encoding tags are configured in the compile-time
configuration file charmaps.cfg.
•
-E=charmap or +E=charmap
with a character encoding name (as reported by the
locale charmap command).
•
-E.suffix or +E.suffix
with a character encoding suffix ("codeset" of locale name).
•
-E:flag or +E:flag
with a 2-letter indication used by mined to indicate the
respective text encoding in the Encoding flag.
In each of these options, -E specifies
text encoding while +E would specify
terminal encoding to be assumed.
The following table lists major encodings and generic
locale suffix values by which they are recognised; in addition
(as mentioned above), a large number of locale names without
encoding suffix as found on various systems in known to mined
and will cause it to assume the corresponding terminal encoding.
UTF-8 terminal (normally auto-detected, included here for
demonstration) and should assume GB18030 text encoding by
default, invoke either of:
LC_ALL=whatever.UTF-8 TEXTLANG=zh_CN.gbk mined
LC_CTYPE=whatever.UTF-8 TEXTLANG=chinese mined
LANG=whatever.UTF-8 mined -EG
LC_ALL=en_IN mined -E.gbk
mined +EU -E.EUC-CN
mined +EU -E=GB18030
mined +EU -E:GB
Selecting UTF-16 text mode: To tell mined to
interpret a file (or make a new file) in UTF-16 encoding, use
the following command line options (first two little endian,
then big endian):
mined -E:61
mined -E=UTF-16LE
mined -E:16
mined -E=UTF-16BE
mined -E=UTF-16
Selecting ASCII terminal mode: To tell mined to
assume that a terminal cannot display anything but ASCII
characters, use the command line option
+E:AS.
Mined implicitly assumes this setting if the environment
variable TERM indicates a VT52 terminal.
PC terminals
Character encoding of PC terminals is an even greater mess
than on Unix systems. Mined provides heuristic best-guess
assumptions about terminal encoding, supporting both local
invocation as well as remote login from a PC (e.g. to a Unix
machine).
The following assumptions are made based on environment variables
or command-line parameters:
encoding ("codepage")
environment

CP850 (PC mapping of Latin-1 character set)

→NEW→
•
cygwin 1.7 console or application configured for UTF-8 mode
•
Note: Windows console in UTF-8 mode provides extended Unicode
font support if you select "Lucida Console" TrueType font from its
Properties menu.
→NEW→ other codepages
LC_*/LANG indicates codepage, e.g. ".CP1250" or ".CP858"
or triggered by DOS codepage information (djgpp version, see note)
+E=CP1250 or other codepage, or respective shortcut
→NEW→
•
cygwin 1.7.0-45 console or cygwin 1.7.0-46 application
configured for respective codepage
Note:
It is not unlikely that the assumption about the terminal
encoding taken by mined does not match the actual terminal
encoding (e.g. mined cannot determine the encoding based on
the ambiguous setting TERM=ansi). Environment variables that
indicate the character encoding are unfortunately not maintained
through telnet or remote login.
Explicitly setting TERM to a suitable value after remote login
or explicitly setting the locale variables, e.g. LC_CTYPE,
may help but may not always work either (e.g. pcansi is not a
known terminal on SunOS; some systems like SunOS are dogmatic
about interpreting locale variables which strictly need to be
installed before; not all encodings, esp. PC "codepages", are
known as a "locale charmap" on other systems).
In these cases, you can use the explicit +E
option to force mined to assume a specific terminal encoding;
see the option values listed above for the main DOS encodings.
Note:
The encoding emulated by cygwin (as configured, by default
Windows Latin codepage CP1252) is not the encoding natively applied
by the Windows console window (by default DOS codepage CP850).
This means that the effective encoding may be different if you
invoke the cygwin-compiled mined version and the
djgpp-compiled mined version alternatingly; you may notice this
by a different range of characters that can be displayed when
opening the same file with the two mined versions.
Some Windows Latin characters are poorly displayed by the
Windows console in default configuration; mined 2000.13 introduced
a workaround to indicate those character by a more suitable
substitution instead. →NEW→
This workaround is withdrawn to support cygwin 1.7 which can
display all characters properly if the Windows console font is
configured to "Lucida Console" rather than "Raster Fonts".
Note:
→NEW→
The following DOS codepages are supported; they are mainly provided
as terminal codepages, they do not appear in the Encoding menu.
However, if you need, you can ask mined to use them as either
the assumed terminal encoding (e.g. +E=CP1250 or +E:WE) or
even text encoding (e.g. -E=CP1250 or -E:WE) using the names

Note:
For the djgpp version of mined, even the font chosen for the
Windows console window may affect the effective display encoding.
Configure "Raster Fonts" (except of size "10 x 20"!), not
"Lucida Console" in order to make sure the effective visual
codepage is the same as the one selected with the respective
DOS tools (e.g. chcp) and assumed by mined.
Note:
The djgpp version of mined running in a UTF-8 mode console
(e.g. with cygwin 1.7) cannot handle this and is confused
by the according setting of locale variables.
Note:
→NEW→
Mined (djgpp) tries to determine the DOS/Windows codepage
using the DOS API; this can only work if the codepage was
properly configured with DOS means (e.g. with CP858 using
CHCP 858 or MODE CON CP SELECT=858, maybe enabled by
DEVICE=...\DISPLAY.SYS CON=(EGA,858) on old DOS, or
MODE CON CP PREP=((codepage list) ...\ega.cpi) );
if only the font is switched to a differently encoded one,
there is no way to detect this.
Sub-Note: This feature has not yet been tested.
If detection does not work, you can still use environment setting
or the +E option as mentioned above
to indicate the terminal encoding.
Note:
Running mined (djgpp) in a dosemu session (DOS emulator on Linux)
works fine, even in an xterm-embedded session although not
perfectly in that case: ^S and ^Q are interpreted for flow
control (thus ^S will hold all output until ^Q is entered),
and the mined option -Qa should be
used to tune menu borders right.
Terminal setup
The Mined runtime support library
includes a configuration file Xdefaults.mined
which lists settings that should be applied to the terminal
for proper operation of several features as described
throughout this manual.
In some terminals, the cursor may not be well visible or not
visible at all if the cursor is on a character
with reverse background (control character, occurs e.g. in xterm)
or highlighted background (invalid character code, occurs e.g.
in xterm and rxvt).
See the X resource parameters for "cursorColor" in the example
configuration file Xdefaults.mined for remedy.
If your terminal scrolls down one line when you click the left
mouse button in the text area, the terminal type is not
properly set up. This occurs, e.g., when you run inside
a cygwin or rxvt terminal but the environment variable TERM
is incorrectly set to xterm. Set it to the correct value for remedy.
If mouse wheel movement moves more than expected, especially
if it cannot move by single items in a menu, this is probably
a configuration issue with your mouse driver.
You are probably running a Windows-based X server which is
(often by default) configured to generate multiple mouse
wheel events on each actual mouse wheel movement.
Often not even in the Control Panel mouse section, but only
in a configuration menu of mouse-specific setup software
(e.g. "Browser Mouse Settings"), configure the scroll unit to 1.
Terminal interworking problems
With some terminals, problems are known due to missing terminal
features or terminal bugs:
any terminal: menu border display
•
If the borders of mined menus appear as letters rather
than graphic borders, the terminal can unexpectedly not handle
VT100 block graphics. Use the option -Qa
to switch to ASCII borders, or -fff
to limit font assumptions.
In a UTF-8 terminal, mined uses Unicode Box Drawing
characters by default.
If they don't display they are missing in the font used by the
terminal.
Use the option -Qv to switch to
VT100 block graphics or -Qa to
switch to ASCII graphics. If borders are visible but without
corners, use -Qs to switch to
rectangular borders.
any terminal: slow terminal feature auto-detection
•
Occasionally, when starting mined, you may receive a message
"Late screen mode response - set ESCDELAY=2000 or higher for proper detection".
This happens if there is a large delay (> 700 ms) in the
interaction mined uses to detect terminal properties.
There are two possible reasons for this:
•
A slow remote terminal connection.
In this case, set up your environment variable ESCDELAY to a
value (in milliseconds) large enough to cover the anticipated
delay, e.g.:
export ESCDELAY; ESCDELAY=3000
•
Font loading. Especially with rxvt and mlterm, X fonts seem
to be loaded partially on demand. While this speeds up initial
terminal operation, it also results in unexpected delays of
terminal responses. In this case, exiting mined and starting
again will normally resolve the issue for one session of the
terminal. For a more permanent remedy, also use the
environment variable ESCDELAY when using those terminals, e.g.:
export ESCDELAY; ESCDELAY=1200
Automatic handling of the situation is planned for the next
release of mined.
mlterm
•
Bidirectional display handling of mlterm is based on the
final display, not regarding any context (such as positioning
control, that's why mined implements a workaround for menu
display on mlterm). This also affects mouse cursor position
reports which do not match over right-to-left text, so the
cursor will be placed somewhere else in the line.
•
The Mined runtime support library
includes a configuration file mlterm/key which
defines enhanced escape sequences for function keys and
other modified keys in order to enable the functionality
described in this manual.
It is essential to use this configuration especially for the
HOP key (keypad "5") which is oppressed by mlterm by default,
and also for Control-punctuation accent prefix functions, and
some others.
•
Note: Mouse wheel scroll navigation in menus
does not work seamlessly in mlterm because mlterm sends incorrect
escape sequences on mouse wheel scrolling.
xterm
•
Although it is a waste of keyboard resources to have two
indistinguishable sets of keypad keys, most terminals provide
no means of distinguish them towards the applications, at least
not by default. Especially for a text editor, it is highly
desirable to distinguish them in order to have a rich intuitive
function key mapping at disposition which mined tries to achieve.
Remapping keypad keys in a useful way is sensitive
because it may create incompatibilities with other programs
that rely strictly on installed terminfo information. Mined
provides remapping recommendations for shifted keypad keys
(with Shift, Control, Alt and combinations of them) in the
configuration sample file Xdefaults.mined in the
Mined runtime support library.
Due to the compatibility limitations mentioned above, however,
the two Ins keys remain indistinguishable, and the two Del keys
are only distinguishable if the xterm configuration resource
*VT100*deleteIsDEL is set. Also, keypad and function key
modification with the Alt is ensured with the xterm resource
*VT100*metaSendsEscape. Both resources are set to true in the
configuration sample file just mentioned.
These two resources can also be set dynamically with xterm.
Mined can be told to do so with the command line option
+D.
(Unfortunately this handling cannot be enabled by default as
it cannot be undone because the previous state cannot be
detected.)
•
Mined determines the xterm version in order to apply
certain workarounds conditionally.
•
If you run xterm in VT220 keyboard mode (using xterm option
-kt vt220 or setting the configuration resource *keyboardType:
vt220) you should make sure to also set the environment
variable TERM=vt220 (e.g. using the xterm option -tn vt220 or
setting the configuration resource *termName: vt220) so mined
can properly set up the keypad functions.
•
If you run xterm with the resource modifyCursorKeys or
modifyFunctionKeys set to value 1, mined will recognize the
according keyboard sequences with the environment variable
setting TERM=xterm-sco.
xterm on cygwin
•
On cygwin, as on other systems, the script uterm
is recommended to invoke an xterm that is properly configured
to run UTF-8, and also to use a best choice of fonts for optimal
Unicode coverage. See README.cygwin for more detailed advice.
xterm legacy CJK width mode
•
Mined auto-detects and supports xterm legacy CJK width
compatibility mode (xterm -cjk_width); character
width and menu border layout are properly adjusted, stylish
menu borders (-QQ) and fine-grained
scroll bar display are disabled by default.
(Note: In this mode, combining characters could unexpectedly
change the width of a character by being substituted with its
wide precomposed form (e.g. 'a' combined with U+0300) -
which an application can hardly handle; this bug was fixed in
xterm 224 with a patch contributed by the mined author.)
rxvt
•
When starting mined in a fresh rxvt terminal, and maybe
even after starting your X server, some display (font?)
initialization may take extremely long, resulting in an error
message. Restart mined to ensure proper terminal properties
auto-detection.
•
Rxvt does not distinguish between Shift-F1 and F11 /
Shift-F2 and F12 / Ctrl-Shift-F1 and Ctrl-F11 / Ctrl-Shift-F2
and Ctrl-F12, so that the F1 and F2 keys modified with Shift
cannot be recognised in rxvt by default.
→NEW→
They can however be enabled with the keysym definitions in
the file Xdefaults.mined in the
Mined runtime support library.
•
In rxvt, the two keypad Del keys (small keypad, numeric
keypad) are automatically distinguished from each other and
invoke the Delete character (small keypad) and Cut (numeric
keypad) functions, respectively (Ctrl-/Shift-/Alt-
alternatives are supported as described in this manual).
This works, however, only if mined can recognise rxvt; it is
generally a bad idea to set TERM=xterm in rxvt, see also
hint below.
•
Also in rxvt, the two keypad Ins keys (small keypad left,
numeric keypad right) are distinguished. The left Ins key
positions the cursor left of the pasted region, the right Ins
key positions it right.
•
By setting rxvt in the mode that enables distinction between
the two keypads, it can unfortunately not distinguish the
right keypad modified with Ctrl- anymore, so Ctrl-Home/End/Del
cannot work as desired.
•
Ctrl-modified punctuation keys can be enabled by
following the configuration samples of the file
Xdefaults.mined in the Mined
runtime support library.
Note: Ctrl-modified and shifted punctuation keys
interfere with ISO 14755 input mode of rxvt; if the following
key is entered twice, that mode is aborted and the modified
punctuation key becomes effective as an accent prefix in mined.
•
The recent rxvt-unicode release provides a CJK terminal
emulation. CJK display is buggy for characters that rxvt
thinks cannot be displayed, especially for GB18030
(LC_CTYPE=zh_CN.gb18030 rxvt) but also e.g. for JIS
(LC_CTYPE=ja_JP.eucjp rxvt); single bytes are then interpreted
instead which amounts to an unpredictable screen width and
cannot be correctly handled.
(This applies mainly to character codes that are not mapped to
Unicode but also to many that are mapped.)
Moreover, CJK width handling is inconsistent for many
characters in rxvt CJK mode (rxvt claims to adhere to the
locale mechanism in this respect but that's not the case here -
character widths are inconsistent with the locale, too).
Remedy: Don't use rxvt in CJK-encoded mode; mined
CJK terminal support is tailored to native CJK terminals (such
as cxterm, kterm, hanterm) where it works fine - if you use a
UTF-8-capable terminal, use it in UTF-8 mode! Mined can edit
CJK-encoded files well in a UTF-8-encoded terminal.
•
In rxvt, Unicode characters that are Not Assigned are
always displayed as a single-width replacement character. This
is not consistent with xterm behaviour which would display
them as a double-width replacement if they are located within
a double-width Unicode range (which sounds reasonable). This
would cause display positioning inconsistencies. Mined has a
workaround for some of these cases (assuming that rxvt runs
the most recent Unicode width data version available; or
actually the same as mined assumes - handling of multiple
auto-detected terminal Unicode versions does not cover this
special case).
•
If the X windows servers has duplicate fonts installed under
a common name (e.g. if it comes with a 10x20 non-Unicode font and
you install a 10x20 Unicode font in addition), rxvt seems to use
the wrong (i.e., non-Unicode) version of the font and does not
find special characters like the default marker used in the flags
menus (this was observed since rxvt 7.5, rxvt 5.8 was finding the
proper font). Use the mined option -F to
adapt mined to limited font usage, or fix the X server installation.
Or use the script uterm to start rxvt-unicode. To
start rxvt-unicode from an xterm, use uterm -rx.
•
Due to the scrollbar display workaround for hanterm (see
above), the scrollbar position may be shown as blank space
instead of coloured (only in rxvt CJK mode with Korean encoding
and if you explicitly set TERM=xterm which you shouldn't
anyway in rxvt).
In this case, coloured scrollbar foreground can be enabled
with the environment variable MINEDSCROLLFG="44;36" or
MINEDSCROLLFG="38;5;45".
•
As a workaround for an xterm bug on cygwin, mined applies
terminal size re-adjustment. This may confuse rxvt (being
resized to an unexpectedly large window) if it pretends to be xterm.
Remedy: in rxvt, make sure that the environment
variable TERM=rxvt (or rxvt-unicode); the according X resource
(Rxvt.termName: rxvt) is also listed in the file
Xdefaults.mined in the
Mined runtime support library.
•
Mined determines the rxvt version in order to use certain
features conditionally.
•
CJK-mode rxvt: rxvt has some character width bugs when running
in CJK encoding; e.g. when running rxvt in Big5 terminal encoding
(locale zh_TW), U+FA18 is displayed with wrong screen width
while in older version U+FFED was display with wrong screen width;
when running rxvt in Shift-JIS terminal encoding, a number of
character width bugs occur. Mined does not implement workarounds
for those; in general UTF-8 terminal encoding is advisable to be
on the safe side.
urxvt
•
This is rxvt-unicode as packaged for cygwin. Invoke it with
a proper locale environment variable set to enable UTF-8.
See also README.cygwin for more detailed hints.
cxterm
•
EUC-JP half-width characters (8EA1-8EDF) are not properly
displayed by cxterm in EUC-JP mode (cxterm -JIS, not available
in "classic" cxterm).
•
Due to the scrollbar display workaround for hanterm (see
above), the scrollbar position may be shown as blank space
instead of coloured (only in Korean encoding mode which is
probably rarely used with cxterm anyway).
In this case, coloured scrollbar foreground can be enabled
with the environment variable MINEDSCROLLFG="44;36" or
MINEDSCROLLFG="38;5;45".
kterm
•
Auto-detection of kterm as a CJK terminal works if the
environment variable TERM indicates "kterm"; otherwise mined
has to be told that it runs in a CJK terminal and which
encoding to use:
For kterm -km sjis, set LC_CTYPE=ja_JP.sjis (or invoke mined +ES).
For kterm -km euc, set LC_CTYPE=ja_JP.eucjp (or invoke mined +EJ).
•
Note: Mouse wheel scroll navigation in menus
does not work seamlessly in kterm because kterm sends incorrect
escape sequences on mouse wheel scrolling.
•
Note: By default (i.e., without explicit -km
option or corresponding *vt100.kanjiMode resource configured),
kterm runs in ISO 2022 mode (yes, it does indeed) which is not
supported by mined.
hanterm
•
CJK display is buggy at the line beginning or after a Tab,
often only the second byte of the character code is displayed
as an ASCII character instead of displaying the complete CJK
character.
•
Character attributes in hanterm used to be all mapped to reverse,
so there was a workaround to enable a visible position in the
scrollbar which is displayed as blank space. The criteria for
this workaround to apply are: CJK terminal (detected or
configured), TERM=xterm, Korean encoding (UHC or Johab)
configured with parameter or locale. Replaced to enable nicer
colours in scrollbar. To reactive workaround for older hanterm,
set environment variable MINEDSCROLLFG="0".
konsole
•
Due to the lack of decent Unicode font support in the default
configuration of the KDE konsole terminal, menu appearance
options -QQ and
-Qr should not be used; rounded
borders are disabled by default.
•
The Mined runtime support library
includes a configuration file konsole/xterm-modified.keytab
which defines enhanced escape sequences for function keys and
other modified keys in order to enable the functionality
described in this manual. Unfortunately, the qt framework
used by konsole inhibits the use of some keys and many key
combinations.
•
It is especially irritating that konsole disregards
the middle keypad key ("5" in application mode) completely;
so the mined HOP function has to be invoked by alternative means.
As a remedy, the HOP function is assigned to the "Menu" key
(next to the "Windows" key on PC keyboards) in the configuration
sample file mentioned above
→NEW→
and is also assigned to the Menu key by default.
An additional remedy could reassign the middle keypad key
to the X key symbol Menu (using xmodmap);
→NEW→
invoke the script kp5 in the
Mined runtime support library for this purpose.
gnome-terminal
•
The gnome-terminal captures a number of Alt-letter key
combinations for its own menu access (which can however also
be controlled with the mouse).
To disable this unpleasant capturing, so e.g. mined can open
its own menus with Alt-letter, configure as follows:
Open menu "Edit" - "Keyboard Shortcuts..." and
check "Disable all menu access keys". Even then, however, F1 and
Ctrl-F1 are suppressed by this quirky terminal.
•
This terminal does not supported modified keys (e.g. shifted
keypad keys).
•
Mined implicitly assumes its -f
option (for limited font usage with respect to graphic
characters) when detecting gnome-terminal.
Linux console
•
Shifted function key codes are "shifted" by 2 as compared
to other terminals' function key codes.
→NEW→
Mined detects F11, F12, Shift-F1...Shift-F8 properly, further
modified function keys are apparently not supported in the
Linux console.
screen
Screen, like luit (see below), is a middle layer between the
actual terminal and the user terminal environment.
Unfortunately, screen does not pass character width handling
of its host terminal transparently to the application but
apparently it maintains cursor position information with
reference to the system-installed locale data. Which, however,
does not always reflect the terminal properties!
→NEW→
Yet mined detects the proper width properties of the host terminal
(by using pass-through escape sequences of "screen") but
only if the environment variable is set to "screen" (the default
of "screen").
MinTTY
MinTTY is a Windows-based (non-X) terminal running with cygwin.
Mined auto-detects MinTTY and adjusts certain properties and
features accordingly.
•
→NEW→
Mined detects font changes that change the CJK ambiguous
character width properties of the terminal when notified by
MinTTY (to be introduced in MinTTY 0.4 or above), if running
in UTF-8 mode.
•
For good coverage of Unicode characters, recommended fonts
for use with MinTTY are Lucida Console, Courier New, Andale
Mono, SimSun. Discouraged are Lucida Sans Typewriter, Letter
Gothic, Courier, Monaco, and older MS CJK fonts, at least for
their lack of (proper) graphic characters (for menu borders).
•
For proper usage of Unix-like keyboards functions, the
following settings are recommended for MinTTY:
In Options - Keys, disable the Shortcuts "Window commands"
and "Copy and paste".
In Options - Text, disable "Show bold as bright".
•
Note: With the command script wined
(also available as wined.bat), mined is invoked
in a separate Windows terminal session, using MinTTY if available.
Cygwin console
•
The cygwin console terminal emulation does not support
Shift-F1, Shift-F2 (which cannot be distinguished from F11, F12),
Shift-F11, Shift-F12, nor any Control or Alt modified function keys.
•
→NEW→
Mined detects UTF-8 mode of cygwin 1.7 console (by LC_*/LANG setting
or for cygwin 1.7 beta by CYGWIN containing "codepage:utf8").
Note: After rlogin from this console, UTF-8 indication has
to be ensured explicitly, e.g. by environment setting, or by
mined option +U.
•
Note: Cygwin console in UTF-8 mode provides extended Unicode
font support if you select "Lucida Console" TrueType font from its
Properties menu.
•
See also README.cygwin for more detailed hints on weird
details about the Windows console in different modes.
•
See also PC terminals above.
Windows console window (DOS command prompt)
•
The Windows console window is normally configured to run
in CP850 encoding; depending on Windows version or font, however,
it may also turn out to use CP437 instead. In this case, some
characters are replaced by graphic symbols, e.g. the sputnik
symbol "¤" used by mined as a replacement character for
non-displayable Unicode characters. This happens, e.g., with the
10 x 20 raster font. As a workaround, use a different font, e.g.
10 x 18 or Lucida Console. If you change the "active codepage",
stay with "Raster Fonts" configuration and avoid the "10 x 20"
size in order to make sure the effective visual codepage is the
same as the selected one and the one assumed by mined.
•
With the djgpp-compiled version apparently there is a
Ctrl-C problem on older Windows versions. Every first
Ctrl-C will display ^C on the screen at the current position
without mined noticing it, while every second Ctrl-C will
be passed to mined. This problem does not occur on Windows XP.
It does occur on Windows ME in a Windows console window.
It does not occur with the cygwin-compiled version.
•
See also PC terminals above.
Poderosa
•
This Windows terminal emulator can be used for UTF-8 editing.
To ensure proper function, do not use Terminal Type "kterm"
or Encoding "euc-jp" or "shift-jis"
•
Mined auto-detection and terminal initialization can cause
Poderosa to display warning popups. To avoid them, Select
Tools - Options... - Terminal; for "Behavior in case of
unexpected chars", disable "Display a message box".
If you get a notice "Failed to decode characters by the
current encoding utf-8.", click "Do not display this message
from next time".
•
Poderosa does not provide mouse support for applications.
Terminator
•
In Edit - Preferences, enable "Use alt key as meta key".
•
Terminator does not provide mouse support for applications.
PuTTY
•
This Windows terminal emulation for remote login provides
various keyboard (esp. keypad and function key) assignment
emulations. In SCO mode, shifted function keys are different
from those of xterm SCO function key emulation; both are
supported.
luit
•
The locale support add-on for text terminals luit which
applies encoding transformations (e.g. with LC_ALL=zh_CN.gb18030)
often maps characters incorrectly, including using the wrong
cell width.
Work-around support to enable 8-bit character set on weird terminals
There exist some exceptionally weird 7 bit terminals that
have an alternative character set containing composed characters
which can be displayed simultaneously with the default character
set. For those there is optional output translation which
embeds non-ASCII characters into the respective code switching
sequences. To enable output character transformation, set the
environment variable MINEDOUT to contain the upper half (with
respect to an 8 bit character set) of the translation table
into the terminal's alternate character set.
(Character set switching will be done as specified in the
termcap (as/ae) or terminfo (smacs/rmacs) entry.)
An example setting of MINEDOUT is included in the environment
sample file profile.mined in the
Mined runtime support library
for Siemens 9780x terminals.
Concerning some especially stupid terminal drivers
There used to be terminal drivers which make use of the
soft handshake mechanism by exchange of ^S and ^Q characters but
yet pass them through to application programs which is quite stupid.
If it is necessary to ignore such hazardous ^S and ^Q keys,
the environment variable NoCtrlSQ or NoControlSQ must be set.
Mined will then not disable the tty channel soft handshake
setting either.
Keyboard mapping / Input method pre-selection
With the environment variable MINEDKEYMAP the active or
standby mapping or both can be preselected. The value is a
two-letter script tag to set the active mapping, or it is
prepended with "-" to set the standby mapping, or a combination.
Example:
export MINEDKEYMAP=-gr
will set Greek keyboard mapping standby.
export MINEDKEYMAP=py-rs
will set Pinyin input method active and Radical/Stroke
input method standby.
The respective tags attached to the keyboard mappings can be
looked up in the Input Method flag menu; the HOP function
toggles between display of the full input method name and its tag.
Smart Quotes style configuration
Smart quotes style can also be preselected with the environment
variable MINEDQUOTES which should then contain the
opening/closing quote pair or just the opening quote mark
(double or single quotes).
Example:
export MINEDQUOTES="»"
sets these »Danish« quotes and corresponding single smart quotes.
export MINEDQUOTES="»»"
sets these »Finnish» quotes and corresponding single smart quotes.
The value of the MINEDQUOTES variable must be encoded in UTF-8.
Han info configuration
With the environment variable MINEDHANINFO, the information
shown for Han characters can be preselected.
If the variable is defined, Han info mode is enabled.
It may contain letters to select description, pronunciation
information, and display mode to be used:
M
show Mandarin pronunciation
C
show Cantonese pronunciation
J
show Japanese pronunciation
S
show Sino-Japanese pronunciation
H
show Hangul pronunciation
K
show Korean pronunciation
V
show Vietnamese pronunciation
P
show Hanyu Pinlu pronunciation
X
→NEW→ show XHC Hanyu Pinyin pronunciation
T
show Tang pronunciation
D
show character description
F
display full information (in popup-menu form);
without F, the information will be shown on the status line
where it is subject to truncation
Common paste buffer configuration
The paste buffers, used for cut/copy/paste operations, as well as
the inter-window paste buffer, are located in a temporary
directory, using system conventions by default.
To maintain the inter-window paste functionality even remotely,
mined uses the environement variables MINEDTMP and MINEDUSER
which, in combination, point to a user-defined temporary directory
and file name pattern to be used for buffer files:
•
Set MINEDTMP to refer to a common mounted network directory
on all machines which means that the value of $MINEDTMP may have
to be different to reflect different mount points across the network.
•
Set MINEDUSER to the same name within the network even if
using different user name accounts.
For details, see also the FILES section below.
Keypad configuration
Some X configuration may have to be applied to enable keyboard
input features as used by mined:
•
Alt key modifier for quicker entry of "ESC" commands.
•
Assignment of the HOP function to the middle keypad key ("5").
•
Assignment of the HOP function to other keys
(especially for convenience on laptops which do not have the
numeric keypad), e.g. the Pause or Scroll Lock key.
•
Distinguish "Home" and "End" keys of the two keypads
in order to make use of this redundancy of typical keyboard layout
(which is actually a waste of physical resources, causing
unnecessary wrist strain because it increase the distance to
be moved over for reaching to the mouse).
•
Enable control and shift modifiers for keypad and function keys.
•
Enable control and shift modifiers for digit keys (for use
as accent prefix).
•
Enable control modifier for punctuation keys (for use
as accent prefix).
See the example file Xdefaults.mined in the
Mined runtime support library for suggestions.
Printing configuration
Mined uses the script uprint from the
Mined runtime support library
to print the current contents of the text being edited
in any selected encoding (unless the environment variable
MINEDPRINT is set to direct mined to use a different print command).
If the support library is not installed in one of its
standard locations (system-dependent), it should be made
available in the usual command search path.
The script uses either paps or
uniprint for actual formatting (print preprocessing).
→NEW→
Under Windows, if neither paps nor
uniprint happens to be installed,
uprint uses notepad /p for printing.
The djgpp-compiled version calls notepad /p directly.
paps is available at
http://paps.sourceforge.net/ and uses the Pango layout
engine for formatting.
uniprint is part of the yudit distribution; if
you don't have it installed on your system, there is another
script makeprint in the support library which can
be used to download and build the needed uniprint program.
The mined print script (uprint) prefers
paps if it is available as it has more capabilities
for printing a wide range of Unicode characters, and it does
right-to-left formatting.
The font to be used with uprint can be configured with
the environment variables FONT, FONTPATH, FONTSIZE.
Also the printer can be configured as usual with PRINTER.
In addition, uprint checks an environment variable LPR for
an alternative for the system printing command (lpr/lp) if
that is needed.
Note: If printing with uprint fails for
some reason, mined tries to print with either the print
command configured in the environment variable LPR as a fallback,
or with lp/lpr as a last resort. Working character encoding
support cannot be expected in this case, however.
See Environment variables to configure Printing
for further details.
Display layout
Some of the special indication characters (that substitute
non-displayable contents) and some of the colours used by mined
for special indications and interactive elements may be
configured to the user's preference.
Note: For the configurable character indications, two
environment variables exist each, to configure an 8 bit value
(Latin-1 encoded) and to configure a Unicode value (UTF-8 encoded).
The UTF-8 encoded values (e.g. MINEDUTFRET) take precedence
in a UTF-8 terminal. In an 8 bit terminal, or if the respective
UTF-8 variable is not configured, the Latin-1 encoded value applies.
See the example script profile.mined
in the Mined runtime support library for
more details and for a number of suggestions of suitable values.
Mined does not apply any default non-Latin-1 indications in order
to avoid display problems with fonts that do not support them.
Depending on your visual preference, there are a number of suitable
Unicode characters for use as indications especially in the Unicode
ranges of Arrows, Geometric Shapes and Symbols (U+2190-U+2BFF).
Note: For the Latin-1 encoded configured indication
markers (variables MINEDRET etc, not MINEDUTFRET etc), if the
configured character is in the small letters range (actually
'`'...DEL) the alternate character set is used for display.
This works also in a UTF-8 terminal, provided that the
corresponding UTF-8-encoded indication configuration variable
is not set, e.g. MINEDRET=j MINEDUTFRET= (or not defined)
would indicate line-ends by displaying a graphic lower right
corner, MINEDTAB='`' MINEDUTFTAB= (or not defined) would indicate
Tab characters with vt100 block graphics lozenge rhombs.
Note: For the UTF-8-encoded configured indication
markers (variables MINEDUTFRET etc), if the marker is a
double-width character, a replacement will be displayed instead.
Note: Mined reduces its assumptions about available
graphic and special characters for display purposes with the
options -f or -F.
The -F option also suppresses the
interpretation of the MINEDUTF* environment variables.
Line ends
Line ends are usually marked by a "«" double left angle character.
This visual indication can be changed with the environment variable
MINEDRET (8 bit terminals) or MINEDUTFRET (UTF-8 terminals).
The default or configured marker is used as an indicator at
the end of every text line on screen (so you can see how many
blank spaces there are).
Multi-character markers: If a second character is configured,
it is used to fill the rest of the screen line, a third
configured character would terminate the indication at the end
of the screen line. ("··«" is a nice setting for people who
used to work at Siemens terminals.)
Pattern:
MINEDRET=123# line end displays as 122222223
Suggestion for a nice line end on UTF-8 mode terminals
(check if character is included in your font, however!):
MINEDUTFRET=⏎# U+23CE
The indication of DOS line ends (CRLF) and Mac line ends (CR)
may be configured with the variables MINEDDOSRET or MINEDUTFDOSRET,
and MINEDMACRET or MINEDUTFMACRET, respectively.
→NEW→
They are also distinguished by different colours.
Paragraph ends
With the option -p, mined displays
distinct indicators for line ends and paragraph ends.
A paragraph is defined to continue while lines end with white
space (space or Tab character).
The default paragraph marker is "¶" and is also used to indicate
a line ending with a Unicode Paragraph Separator. It can be
changed with the environment variable MINEDPARA or MINEDUTFPARA.
Tab characters
Tab characters are usually indicated by a sequence of '·'
(middle dot) characters.
This can be changed with the environment variable MINEDTAB
(8 bit terminal) or MINEDUTFTAB (UTF-8 terminals).
Multi-character markers: If two characters are configured,
the second is used to mark the middle of the Tab span. If three
characters are configured, the first and last are used to mark
the beginning and end of the Tab span.
Pattern:
MINEDTAB=123# Tab displays as 12222223
MINEDTAB=12# Tab displays as 11112111
Long lines
Lines which are too long for the screen are usually indicated
by a '»' double right angle (guillemot) character. If the current
position is behind the screen margin, the line is shifted out left
which is indicated by a '«' double left angle.
These markers can be changed with the environment variable
MINEDSHIFT or MINEDUTFSHIFT. The first character is used to
indicate a line continued to the left of the screen, the second
character is used to indicate a line continued to the right of
the screen.
Unicode characters
For a description of special display indications in UTF-8 text
editing mode see "Unicode display" above.
The indication and highlighting mode of a non-displayable Unicode
character (typically a UTF-8 character in a Latin-1 terminal),
as well as the highlighting mode (colour) of the indication of
illegal UTF-8 sequences, can be configured with the variable
MINEDUNI.
Display mode of indicators
It is recommended to display these indicator characters in a dim
display mode to prevent distraction from the text contents. The
default is a red colour which is a moderate dark red in xterm.
The display mode can be used by placing the code part of an ANSI
display control sequence in the environment variable MINEDDIM.
E.g., MINEDDIM=31 would select the default mode, red foreground;
in xterm only, MINEDDIM="38;5;83;38;5;245" gives a moderate gray
in either 88 or 256 color mode;
in rxvt only, MINEDDIM="38;5;83" gives a moderate gray.
→NEW→
MINEDDIM can also be set to an empty value to have mined apply
dim colour to the indications; the colour value is computed
from the current foreground and background colours (works
in xterm). The ANSI colour 7 (white) is temporarily
redefined for this purpose and restored when mined exits.
Display mode of menu borders
→NEW→
The display colour of menu borders and menu headers can be
configured with the environment variable MINEDBORDER.
Suitable values are "35" (magenta), "34" (blue) and "31" (default).
Status line highlighting
Highlighted parts of status line messages (e.g. initial letters
for help selection after F1) can be configured with the
environment variable MINEDEMPH, using foreground ANSI modes.
The default is "31" (effectively red background).
Scrollbar colour
The foreground and background colours of the scrollbar can
be configured with MINEDSCROLLFG and MINEDSCROLLBG, respectively,
using ANSI modes; if only the background is configured,
the foreground is the reverse of it. In general, to support
fine-grained scrollbar display in UTF-8 terminals, the
foreground and background colour settings should be the
reverse of each other.
The default for the background is "46;34;48;5;45" if
use of 256 colour mode is enabled, or "46;34" if it is disabled.
The default for the foreground is "", meaning that the reverse
background is used, with a workaround for hanterm (see above).
Menu colour and border style
The highlighting background colour of the selected menu item
can be configured with MINEDSEL, using reverse ANSI modes (i.e.
using foreground parameters for the background) and MINEDSELFG
for the foreground, using reverse ANSI modes. The default values
are MINEDSELFG="43" and MINEDSEL="34", giving yellow on blue.
If selected menu items appear too dark (which mined tries to
avoid, depending on the terminal), try one of the workarounds
MINEDSEL="34;1" or MINEDSELFG="43;1".
Menu border styles can be selected with the option
-Q.
For a nice selection bar that extends from left to right menu
border, the setting -QQ is
recommended (this is the default unless the terminal is
assumed not to provide sufficient font configuration for this
option; it depends on certain graphic Unicode characters being
included in the terminal font and can be disabled with
-Qq).
Combining character display
The highlighting background colour of combining characters
displayed in separated mode can be configured with
MINEDCOMBINING, using ANSI background modes.
The default value is MINEDCOMBINING=46, to change colour e.g.
to yellow background, use MINEDCOMBINING=43.
Online Help access
Mined looks for its online help file in a number of typical
directories for installation of the Mined runtime support library.
If it is placed in a non-standard location, the environment
variable MINEDDIR should point to the directory.
(Mined also tries to find the online help file in the directory
where it was started from; this is especially useful for the
DOS/Windows version.)
Mined configuration
Script highlighting
The the mined distribution contains a file
src/colours.cfg; it contains entries with the
script name (as listed in the Unicode data file
Scripts.txt), blank space, and a colour index
into the xterm 256-colour mode. (To make good use of 256
colour mode, the terminal program should be compiled with 256
colour support enabled. Configure xterm with
configure \-\-enable-256-color .)
Edit colours.cfg before building mined to
adapt coloured script display to your preferences.
Encodings and Encoding menu
The mined distribution contains a file src/charmaps.cfg
which defines the character encodings that mined knows and how
they are presented in the Encoding menu, together with flags for
indication in the Encoding flag and tags for use with the
-E and +E
options (and the MINEDDETECT environment variable).
The configuration file allows the definition of sub-menus in the
Encoding menu.
Each character encoding entry charmap-name must
correspond to an existing character mapping file
charmaps/charmap-name.map.
Additional character mappings can be generated with the script
mkchrmap.
Encodings recognised by locale names
The mined distribution contains a file src/locales.cfg
which maps locale names to associated character encodings.
While this list contains mainly locale names without explicit
encoding suffix, mined also checks generic locale name suffix
values and assumes the corresponding terminal encoding.
Thus the given names or suffixes can be used even on legacy
systems without locale support to indicate the terminal
environment and preferred text encoding properly to mined.
Keyboard mapping (Input method)
The mined distribution contains a file src/keymaps.cfg
and a script mkkbmap; go into the
src directory and use the script to generate
additional keyboard mappings:
The parameter to the mkkbmap script can be one of
path.../name.mim
a keyboard mapping file of the m17n-db multilingualization package
path.../name.kmap
a keyboard mapping file of the yudit text editor
path.../name.vim
a keyboard mapping file of the vim text editor
path.../name.cit
an input method mapping file of the cxterm terminal,
binary form; only works if the cxterm binary/text
conversion utility cit2tit is accessible
path.../name.tit
an input method mapping file of the cxterm terminal,
text form; only works if the character set
conversion utility iconv is accessible and
works on the mapping file
path.../name.utf
an input method mapping file of the cxterm terminal,
already converted to UTF-8 encoding (e.g. with iconv)
Cangjie [ < HKSCS Changjie table file name > ]
with this tag, a keyboard mapping for the Cangjie input method
will be generated,
taking information from the Unihan database (unicode.org);
with a second parameter, a Big5-encoded table of HKSCS
Changjie input codes will be merged in,
the parameter is either the file name or a +
sign which is implicitly expanded to the relative path name
etc/charmaps/hkscs/hkscs-2004-cj.txt;
the HKSCS input codes file should be taken from
http://info.gov.hk/digital21/eng/hkscs/
MainlandTelegraph , TaiwanTelegraph
with one of these tags, a keyboard mapping will be generated
using one of these telegraph codes as an input method,
taking information from the Unihan database (unicode.org)
Cantonese , HanyuPinlu , Mandarin , Tang
with one of these tags, a keyboard mapping will be generated
using the according Chinese pronunciation as an input method,
taking information from the Unihan database (unicode.org)
JapaneseKun , JapaneseOn
with one of these tags, a keyboard mapping will be generated
using Japanese or Sino-Japanese pronunciation as an input method,
taking information from the Unihan database (unicode.org)
Korean , Vietnamese
with one of these tags, a keyboard mapping will be generated
using Korean or Vietnamese pronunciation as an input method,
taking information from the Unihan database (unicode.org)
VIQR , VNI , Vtelex
with one of these tags, a keyboard mapping will be generated
for the respective Vietnamese input methods,
taking character information from the Unicode database (unicode.org)
script tag
for many scripts listed in the UnicodeData.txt database,
character names listed there can build a useful
keyboard mapping;
mkkbmap will then generate an according
keyboard mapping file, e.g. for Bopomofo
Each successful generation of a mapping table adds an entry
to the configuration file keymaps.cfg; the
entry is however initially disabled as it usually needs manual
adjustment: edit the configuration file; enable the new
entry by removing the leading '#' character, check the first
element which will be the name of the mapping to appear in the
Input Method menu, check the last element of the entry
which is a two-letter shortcut and must be unique for all
mappings, then move the entry to the position where you want
it to appear in the menu. You can also group mappings by
adding "-" lines in this configuration file.
For the Unicode data version used for included keyboard mappings,
see the mined change log.
For the keyboard mappings generated from Unihan data,
characters are sorted according to the priorities of their
Unicode ranges (assigning lower priority to "Supplement" and
"Extension" and "Compatibility" ranges).
So for some input mnemos, the "pick list" for the Cangjie
input method is displayed more in order of relevance (since
2000.10).
For keyboard mappings for CJK encodings, mkkbmap will add
appropriate punctuation mapping entries for Chinese, Japanese,
Korean, respectively, in addition to the entries derived from
the respective data source.
MSDOS-only notes
DOS binaries: Two DOS-based versions, compiled with djgpp
and with cygwin, are available for download from the
mined web site
http://towo.net/mined/
for users who want a quick binary on DOS-based systems.
The djgpp binary is a "dual-mode" executable which runs on
plain DOS and also supports long file names in a Windows
98/2000/XP/... console window (not NT4.0). It does not run
in an xterm, however.
Highlight mode:
The ANSI codes for selecting normal and exposed display can be
chosen with the environment variable MINEDCOL. The two
selections are separated by a space. Each selection is a
semicolon-separated list of the code values.
The default behaviour corresponds to the setting
set MINEDCOL=7 27
Example: Green on red text, red on green status:
set MINEDCOL=34;42 32;44
For command line options, "/" can be used instead of "-".
The "ESC -" command cannot go back within a group of
files named by the same wildcard expression. It goes to
the previous file name (or wildcard expression) instead.
Enabling the keypad HOP key: If you have a very old and
crappy BIOS, you may have to enable use of the cursor block
"5" key (for use as a HOP key) with a TSR driver (ENHKBD.COM)
or an enhanced keyboard driver.
(Older PC keyboard drivers were often so ignorant
to forbid you to use that key.)
Immediate adjustment to changed window size does not work in
the DOS version if the size change is caused by a TSR (e.g.
VGAMAX using a hotkey); in that case, mined adjusts its
screen display only after the next key is typed.
The cygwin terminal environment (cygwin in a Windows console
window) provides an emulation of a Unix 8 bit character set so
non-ASCII characters entered in this version are different
from those entered in other DOS-based versions.
Editing UTF-8 text, on the other hand, works transparently in
all DOS-based versions.
See PC terminals above for more details.
In order to enable mouse use in a Windows console window,
deactivate "QuickEdit mode" in the properties menu.
The following only applies if DOS ANSI driver output is used
which is currently not the case in any configuration:
The default colour setting depends on an extended ANSI driver
(like NNANSI) as does the scroll down function anyway.
Unfortunately, there is no way to find out the current colour
setting nor is there an inverse video mode in many ANSI
drivers (only a fixed black on white mode) so that it is
impossible to implement just inverse display for highlighting.
Therefore, if mined thinks to see an ANSI driver of the
simpler kind, it will change its colour setting defaults. In
any case, these can be overridden with the MINEDCOL variable.
Recommended ANSI drivers:
NNANSI by Tom Almy (very capable, but needs some
installation effort), or
ANSI.COM by Michael J. Mefford (small, works well at
usual screen sizes).
Mined tries to analyse the ANSI drivers capabilities by
checking some control sequences. This works, however, only if
the ANSI driver is at least able to send cursor position
reports.
For primitive ANSI drivers that cannot even do that, mined's
operation can be ensured with an emergency procedure:
A faked pseudo-report should be stuffed into mined as its
first input (with some key-stuffing program) and mined will
use no further cursor position requests. It will also assume a
simple ANSI driver then. The faked report should consist of
the screen size in lines and columns, embedded at the
positions of the ANSI cursor report sequence but with
different surrounding characters. For an invocation of mined
on a 25 lines and 80 columns screen a batch file for this
would look like:
keypress xx25x80xx
mined %1 %2 %3 %4 %5 %6 %7 %8 %9
The remaining remarks apply to the Turbo-C version only
which is no longer supported (use djgpp instead):
•
The file size being edited is limited to 200KB to 500KB
(depending on average line length and number of lines).
•
Typing of Ctrl-P while display output is active
(i.e., during screen paging) can hang the system. Typing of
Ctrl-C or Ctrl-Break while display output is active can
at least leave some garbage on the screen. Ctrl-S may stop
screen output until Ctrl-Q is typed. Typing of
Ctrl-P, Ctrl-C, or Ctrl-Break while a search
operation is active can be desastrous. (Can anyone tell me how
to disable BIOS/MSDOS interpretation of these characters from
Turbo-C?)
•
The Turbo-C version is configured to handle screen output
using the "conio" module. (It used to use an ANSI driver.)
The disadvantage of conio is that it doesn't handle arbitrary
screen modes and sizes whereas good ANSI drivers support them
all.

DIAGNOSTICS
In all cases where it is considered sensible, the appropriate
message of a system error occurred is displayed (instead of
printing numerical hieroglyphs or indistinguished commonplace
messages as many other UNIX tools do).
BUGS
In an extremely narrow terminal window (less than 8 characters),
if lines are shifted out of the display, moving the cursor around
may cause positioning errors and display garbage.
(Unix:) Mined cannot edit a pipe or device file and hangs if
you try to do so. (But it can insert from, or write to, a pipe.)
This restriction does not refer to editing from standard
input in a piped command like cmd | mined
which works of course.
(MSDOS, Windows:) With non-cygwin versions (djgpp), piped
editing from standard input does not work for unknown reason.
(Windows:) Non-cygwin versions (djgpp) do not work in xterm,
rxvt, or MinTTY.
AUTHOR AND ACKNOWLEDGEMENTS
Long ago, the initial version of mined was written for the Minix
educational operating system by Michiel Huisjes.
It was adapted to Unix by Achim Müller who added termcap support.
Mined was later debugged, partly rewritten and enhanced and
is now maintained by Thomas Wolff.
