To my surprise there is no lightweight / decent / comfortable IRC client for N900. Few days ago I have discovered sicelo posted his "Irssi 0.8.17 for N900, with perl script support" and this solved the problem for me. Here is how I'm using it. I thought that I would share my setup here (nothing special but you will have perfect IRC client in about 2-3 minutes of tweaking). [Separate highlight buffer is not covered here but I would add it too.]

The result is Irssi running fullscreen in native osso-xterm with bottom bar hidden (a lot more space!), nicks being colored and windows switching / scrolling using touch.



To hide xterm bottom bar in fullscreen:
[TIP #1: Invoking this command once makes the bottom bar always hidden when starting new xterm and going fullscreen; bool "true" to disable]

[TIP #2 When fullscreen press CTRL+Backspace to display task switcher / close window]

Scripts [~/.irssi/scrips/autoload/]:

- colorize nicks: http://scripts.irssi.org/scripts/nickcolor.pl

- windows switching / scrolling using touch: http://wouter.coekaerts.be/irssi/mouse

The mouse.pl uses mouse wheel to scroll by default so modify the script changing:

to:

This way Irssi looks extremely readable and swipe left / right changes to next / previous window and swipe up / down scrolls the buffer. PERFECT!

Nice one.
