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.
