view ply-3.8/test/lex_state2.py @ 12399:1d5984a87122 draft

<oerjan> addquote <fizzie> I could write a script to my own irssi instance to periodically check if it\'s missing; if so, whois it to verify it\'s connected and authenticated; then set that ignore list and tell it to join. But maybe it\'s just easier to fix those things in the Befunge code.
