OPTIONS
major options
--version
prints the version and compiletime variables.
--help
prints usage information.
--secure
runs Jed in secure mode, e.g. you can't run any external commands with
system()
or
run_shell_cmd().
--batch
run Jed in batch mode.
This is a non-interactive mode.
--script
this is a mode like
--batch
but jed does not eval the startup files. It behaves like
slsh.
You must give the file that should be evaluated as second argument. It's
the same as calling
jed-script.
minor options
-n
do not load
.jedrc
file.
-a 'file'
load
file
as user configuration file instead of .jedrc.
+ 'n'
goto line
n
in buffer (notice that in order to this option to take effect, if must
appear before the file name in the command line, like 'jed +3 file')
-g 'n'
goto line
n
in buffer (notice that in order to this option to take effect, if must
appear after the file name in the command line, like 'jed file -g 3')
-l 'file'
load
file
as S-Lang code.
-f 'function'
execute S-Lang function named
function
-s 'string'
search forward for
string
-2
split window
-i 'file'
insert
file
into current buffer.
X options
xjed
accapts the common options like
-display, -name, -fn and -geometry.
Additionaly it accepts
-facesize SIZE, -fs SIZE
if build with XRENDERFONT support, selects the font size
SIZE.
Use it with the option
-fn
to select a scalable font.
-foreground COLOR, -fg COLOR
sets the foreground color.
-background COLOR, -bg COLOR
sets the background color.
-fgMouse COLOR, -mfg COLOR
sets the foreground color of the mouse pointer.
-bgMouse COLOR, -mbg COLOR
sets the background color of the mouse pointer.
-Iconic, -ic
start iconified.
-title NAME
sets the window title to
NAME.
For more options look at
xterm.c.
CONFIGURATION
Emulating Other Editors
JED's ability to create new functions using the
S-Lang
programming language as well as allowing the user to choose key bindings,
makes the emulation of other editors possible. Currently, JED provides
reasonable emulation of the
Emacs, EDT, and Wordstar
editors.
Emacs Emulation
Emacs Emulation
is provided by the S-Lang code in
emacs.sl.
The
basic functionality of Emacs is emulated; most Emacs users
should have no problem with JED. To enable Emacs emulation in JED, make sure
that the line:
() = evalfile (emacs);
is in your
jed.rc
(.jedrc) startup file. JED is distributed
with this line already present in the default jed.rc file.
EDT Emulation
For
EDT
emulation,
edt.sl
must be loaded. This is accomplished by
ensuring that the line:
() = evalfile (edt);
is in present in the jed.rc (.jedrc) Startup File.
Wordstar Emulation
wordstar.sl contains the S-Lang code for JED's Wordstar
emulation. Adding the line
() = evalfile (wordstar);
to your jed.rc (.jedrc) startup file will enable JED's
Wordstar emulation.
RUN TIME
Status line and Windows
JED
supports multiple windows. Each window may contain the same
buffer or
different buffers. A status line is displayed immediately below
each
window. The status line contains information such as the JED
version
number, the buffer name,
mode,
etc. Please beware of the
following indicators:
**
buffer has been modified since last save.
%%
buffer is read only.
m
Mark set indicator. This means a region is being defined.
d
File changed on disk indicator. This indicates that the
file associated with the buffer is newer than the
buffer itself.
s
spot pushed indicator.
+
Undo is enabled for the buffer.
[Narrow]
Buffer is narrowed to a region of LINES.
[Macro]
A macro is being defined.
Mini-Buffer.
The
Mini-Buffer
consists of a single line located at the bottom of the
screen. Much of the dialog between the user and JED takes place in this
buffer. For example, when you search for a string, JED will prompt you
for the string in the Mini-Buffer.
The
Mini-Buffer
also provides a direct link to the S-Lang interpreter.
To access the interpreter, press
Ctrl-X Esc
and the
S-Lang>
prompt will appear in the Mini-Buffer. Enter any valid S-Lang expression for
evaluation by the interpreter.
It is possible to recall data previously entered into the
Mini-Buffer
by using the up and down arrow keys. This makes it possible to use and edit
previous expressions in a convenient and efficient manner.
Basic Editing
Editing with JED
is pretty easy - most keys simply insert themselves.
Movement around the buffer is usually done using the
arrow keys or page up and page down keys.
If
edt.sl
is loaded, the keypads on
VTxxx
terminals function as well. Here, only the
highlights are
touched upon
(cut/paste operations are not considered `highlights').
In the following, any character prefixed by the
^
character denotes a
Control character. On keyboards without an explicit Escape key,
Ctrl-[
will most likely generate and Escape character.
A
prefix argument
to a command may be generated by first hitting the
Esc
key, then entering the number followed by pressing the desired
key. Normally, the prefix argument is used simply for
repetition. For
example,
to move to the right 40 characters, one would press
Esc 4 0
followed immediately by the right arrow key.
This illustrates the use of the repeat argument for repetition.
However, the
prefix argument may be used in other ways as well. For example,
to begin
defining a region, one would press the
Ctrl-@
key. This sets the mark and begins highlighting.
Pressing the
Ctrl-@
key with a prefix
argument will abort the act of defining the region and to pop the
mark.
The following list of useful keybindings assumes that
emacs.sl
has been loaded.
Ctrl-L
Redraw screen.
Ctrl-_
Undo (Control-underscore, also Ctrl-X u').
Esc q
Reformat paragraph (wrap mode). Used with a prefix
argument. will justify the paragraph as well.
Esc n
narrow paragraph
(wrap mode). Used with a prefix
argument will justify the paragraph as well.
Esc ;
Make Language comment (Fortran
and C)
Esc \\
Trim whitespace around point
Esc !
Execute shell command
Esc $
Ispell word
Ctrl-X ?
Show line/column information.
`

next char as is (backquote key)
Esc s
Center line.
Esc u

Esc d
Downcase word.
Esc c
Capitalize word.
Esc x
Get M-x minibuffer prompt with command
completion
Ctrl-X Ctrl-B
pop up a list of buffers
Ctrl-X Ctrl-C
exit JED
Ctrl-X 0

Ctrl-X s
save some buffers
Ctrl-X Esc
Get "S-Lang>" prompt for interface to the S-Lang
interpreter.
Esc .
Find tag
Ctrl-@
Set Mark (Begin defining a region). Used with a
prefix argument aborts the act
of defining the region and
pops the Mark.
FILES
JED_ROOT/lib/*.sl
these are the default runtime jed slang files
(packages like jed-extra can define additional slang library directories)
JED_ROOT/lib/site.sl
This is the default startup file.
/etc/jed.d/*.sl
The system wide configuration files
(this is a special Debian feature).
~/.jedrc
Per user configuration file, or
~/.jed/jed.rc
per user configuration file if the Jed_Home_Directory
~/.jed/
