NAME

megahal interfaces - C, Python and Tcl interfaces to Megahal  

SYNOPSIS

#include <megahal.h>


void megahal_setnoprompt(void);

void megahal_setnowrap(void);

void megahal_setnobanner(void);

void megahal_seterrorfile(char *filename);

void megahal_setstatusfile(char *filename);

void megahal_initialize(void);

char *megahal_initial_greeting(void);

int megahal_command(char *input);

char *megahal_do_reply(char *input, intlog);

void megahal_output(char *output);

char *megahal_input(char *prompt);

void megahal_cleanup(void);


 

DESCRIPTION

Initialization
Megahal is initialized with the megahal_initialize() function. megahal_setnoprompt eliminates the prompt from interactive sessions. megahal_setnowrap() stops output from being wrapped. megahal_setnobanner() prevents megahal from printing out the initial 'banner'.

Files
megahal_seterrorfile and megahal_setstatusfile set which files megahal will use for error and status reporting, respectively.

User interaction
megahal_initial_greeting returns an initial greeting for the user, such as "hello", "ciao", etc... megahal_command checks its input for a Megahal command (like QUIT), and acts upon it, if found. If it finds nothing, it returns 0. megahal_do_reply is the core of megahal. It takes a string as input, and calculates a reply, which it returns. meghal_output is for outputting text to stdout, such as megahal's replies. Input may be obtained with megahal_input, which takes a prompt string as an argument, and returns a string input by the user.

Example
main.c in the source distribution is a good example of how to use Megahal's C API.

 

TCL INTERFACE

load libmh_tcl.so
Load the Tcl interface shared object into the Tcl interpreter.

mh_init
Initialize megahal brain.

mh_doreply text
Takes some text as input and returns a megahal reply.

mh_cleanup
Save megahal brain to disk. You will lose your changes if this does not occur.

 

PYTHON INTERFACE

import mh_python
Import the Megahal Python interface into the Python interpreter.

mh_python.initbrain()
Initialize megahal brain.

mh_python.doreply(text)
Takes some text as input and returns a megahal reply.

mh_python.learn(text)
Takes some text as input and updates the model without generating a reply.

mh_python.cleanup()
Save megahal brain to disk. You will lose your changes if this does not occur.
