Irssi plugin for Unicode math notation

spugtex

An irssi plugin for Unicode math notation.

This plugin replaces LaTeX symbol names with their respective Unicode characters in your outgoing messages.

Usage

/math <some nice math> Replaces the symbol keywords in your message with Unicode symbols.

/mathp <some nice math> Prints a preview of the message to the current window. Alias for /spug preview <math>

/spug list Lists all supported symbols to the current window.

Examples

 /math Lambda = alpha/omega
 Λ = α/ω

Installation

Copy this file to your irssi scripts directory:

 $ wget -O ~/.irssi/scripts/spugtex.pl https://raw.github.com/seece/spugtex/master/spugtex.pl 

and load the script in irssi with

 /script load spugtex.pl 

On fonts

Not all fonts support the math symbols spugtex outputs. One good choice for a terminal/IRC font is Deja Vu Mono.

spugtex's Issues

Issues with symbols

Some symbols give wrong characters and some symbols are missing.

The symbol list needs reviewing and enhancements.

Extensions & Ideas

Maybe extend this script to include all kinds of unicode characters other than math and rename to /u, /utf /unicode

Also support for custom codes for example /u add conj 2227 -> /u A conj B -> A ∧ B
Maybe /u rename oldname newname, /u remove name

Set unicode mode

Maybe I'm trying to explain some logic conundrum to a friend and I need to send many lines of explanation. It might be nice to be able to say for example /set unicode ON and the scripts converts everything until I say /set unicode off.
