sedbot
======
sedbot is an IRC search-replace bot written using bash and sed.
Usage: Edit the settings on top of sedbot.bash and run it under an unprivileged user.
Only the s command and g and i flags are supported. Multiple regular expressions can be used at once, delimit them with spaces in between the flags and the s next one's s command. The last one may omit the trailing / if it has no options.
Example usage in chat:
<foo> Hello ther!
<foo> s/ther/there
<sedbot> <foo> Hello there!
<foo> I'm programmign right now
<bar> foo: s/gn/ng/
<sedbot> <foo> I'm programming right now
<foo> abcdefghi
<foo> s/\(.\)./\u\1/g s/
<sedbot> <foo> ACEGi
<foo> s/[a-e]//g s/\(.\)\(.\)/\2\1
<sedbot> <foo> gfhi
Note that the bot uses the standard grep (POSIX) regular expressions, i.e. use `.\+` and `\(foo\)\?` instead of `.+` and `(foo)?` as you'd do in egrep or other regex engines. Backreferences are written like `s/\(.\)/\1`, where `\1` matches the first capturing group.
