fungot, a Funge-98 bot

This is fungot, an IRC bot written in Funge-98.

Assorted details related to its operation follow, but there is no "proper" documentation. For details, your best bet is probably to find fizzie on the Libera.Chat IRC channel #esolangs.

(On the other hand, why are you even interested?)

Features

• Built-in brainfuck and Underload interpreters.
• User-defined commands based on the above interpreters.
• Nonsense generation based on variable-length ngram models.
• That's about it, really.

Running

Requires: a Funge-98 interpreter with support for the STRN, FILE, FING, SOCK, SCKE, REXP, TOYS and SUBR fingerprints. SCKE is not actually used, so you may remove the loading of it. TOYS is only used for the ^reload command. SUBR is used for ^code. REXP is used for the ignore feature. The canonical instance on #esoteric runs on cfunge.

To run, you should modify one of the fungot-load-*.b98 files and then run it. It will load the fungot.b98 by itself. The files should hopefully be more or less self-documenting. Remember not to misalign any vs or <s. Administrative commands such as ^ignore and ^save are only accepted if the associated nick!user@host prefix matches the one set in the file.

It might be necessary to create the file data/fungot.dat and put ten empty lines there. Available babbling styles are loaded from the file styles.list, which should contain lines of the form "label\0description\0" (those are actual 0 bytes) and be terminated with a line containing a single "\0". The babbling model files are then model.bin.<label> and tokens.bin.<label>.

Check the standard output of your Funge interpreter for connection details. Use ^raw JOIN #channel (as an administrator) in a private message, afterwards.

There might be other details that elude me at the moment.

Commands

The command prefix used here is the default ^, but you can change that in the configuration file.

Public:

• ^bf <code>[!<input>]: Run as brainfuck code. Optional input separated with !.
• ^ul <code>: Run as Underload code.
• ^def <command> <lang> <code>: Define command to run code in lang (one of bf or ul).
• ^show [<command>]: List defined commands, or show source code for one.
• ^str 0-9 get/set/add [<text>]: Used to define commands longer than the IRC message length.
• ^style [<style>]: Select babbling model, or show the current/available ones.
• ^bool: If you have yes/no questions in need for answers.

Administrator-only:

• ^raw <text>: Send the argument as a raw IRC message.
• ^save: Save current persistent state (defined commands and ^str strings).
• ^ignore [<regex>]: Show or set the ignore regex. It is matched against the nick!user@host prefix.
• ^reload: Reload the fungot.b98 file. Not used very often. Might break things.
• ^code <text>: Run the argument as Funge-98 code. Needs SUBR. Very likely to break things.
