I use xchat as my IRC client, and I have a couple of plugins I use with it.
- debianbugs.py provides URLs for Debian bug numbers.
- topicdiff.py provides a word-based diff for topic changes. Originally by Scott James Remnant.
- whiteout.py shows ignored messages with the same foreground and background colors, rather than hiding them completely. This lets you see when ignored people are participating, without having to read what they say. This lessens confusion.
- Using stuff on code.liw.fi
- Version control:
git clone git://git.liw.fi/xchat-plugins-liw
- Tarball and Debian packages: http://code.liw.fi/debian/pool/main/x/xchat-plugins-liw/
