%U%_When to match%_%U
%UOn which types of event to trigger%U
These are simply specified by -name_of_the_type
The normal IRC event types are:
publics, %|privmsgs, (pub|priv)actions, (pub|priv)notices, (pub|priv)ctcps, (pub|priv)ctcpreplies, joins, parts, quits, kicks, topics, invites, nick_changes, dcc_msgs, dcc_actions, dcc_ctcps
mode_channel: %|a mode on the (whole) channel (like +t, +i, +b)
mode_nick: %|a mode on someone in the channel (like +o, +v)
-all is an alias for all of those.
Additionally, there is:
rawin: %|raw text incoming from the server
send_command: %|commands you give to irssi
send_text: %|lines you type that aren't commands
beep: %|when irssi beeps
notify_join: %|someone in you notify list comes online
notify_part: %|someone in your notify list goes offline
notify_away: %|someone in your notify list goes away
notify_unaway: %|someone in your notify list goes unaway
notify_unidle: %|someone in your notify list stops idling
(pub|priv)flood: %|flood in a channel or in private detected. See /set flood. Be careful, these flood signals can trigger many times for one flood (unless you have autoignore enabled)
%UFilters (conditions) the event has to satisfy%U
They all take one parameter. If you can give a list, seperate elements by space and use quotes around the list.
All filters except for -pattern and -regexp can also be inversed by prefixing with -not_.
-pattern: %|The message must match the given pattern. ? and * can be used as wildcards
-regexp: %|The message must match the given regexp. (see man perlre)
%|if -nocase is given as an option, the regexp or pattern is matched case insensitive
-tags: %|The servertag must be in the given list of tags
-channels: %|The event must be in one of the given list of channels.
Examples: %|-channels '#chan1 #chan2' or -channels 'IRCNet/#channel'
%|-channels 'EFNet/' means every channel on EFNet and is the same as -tags 'EFNet'
-masks: %|The person who triggers it must match one of the given list of masks
-hasmode: %|The person who triggers it must have the give mode
Examples: %|'-o' means not opped, '+ov' means opped OR voiced, '-o&-v' means not opped AND not voiced
-hasflag: %|Only trigger if friends.pl (friends_shasta.pl) or people.pl is loaded and the person who triggers it has the given flag in the script (same syntax as -hasmode)
-other_masks
-other_hasmode
-other_hasflag: %|Same as above but for the victim for kicks or mode_nick.
%U%_What to do when it matches%_%U
-command: Execute the given Irssi-command
%|You are able to use $1, $2 and so on generated by your regexp pattern.
%|For multiple commands ; can be used as seperator
%|The following variables are also expanded:
$T: %|Server tag
$C: %|Channel name
$N: %|Nickname of the person who triggered this command
$A: %|His address (foo@bar.com),
$I: %|His ident (foo)
$H: %|His hostname (bar.com)
$M: %|The complete message
${other}: %|The victim for kicks or mode_nick
${mode_type}: %|The type ('+' or '-') for a mode_channel or mode_nick
${mode_char}: %|The mode char ('o' for ops, 'b' for ban,...)
${mode_arg} : %|The argument to the mode (if there is one)
%|$\X, with X being one of the above expands (e.g. $\M), escapes all non-alphanumeric characters, so it can be used with /eval or /exec. Don't use /eval or /exec without this, it's not safe.
-replace: %|replaces the matching part with the given replacement in the event (requires a -regexp or -pattern)
-once: %|remove the trigger if it is triggered, so it only executes once and then is forgotten.
-stop: %|stops the signal. It won't get displayed by Irssi. Like /IGNORE
-debug: %|print some debugging info
-last: %|Don't process any more triggers for this message
%U%_Other options%_%U
-disabled: %|Same as removing it, but keeps it in case you might need it later
-name: %|Give the trigger a name. You can refer to the trigger with this name in add/del/change commands
%U%_Examples%_%U
Knockout people who do a !list:
%#/TRIGGER ADD %|-publics -channels "#channel1 #channel2" -nocase -regexp ^!list -command "KN $N This is not a warez channel!"
React to !echo commands from people who are +o in your friends-script:
%#/TRIGGER ADD %|-publics -regexp '^!echo (.*)' -hasflag '+o' -command 'say echo: $1'
Ignore all non-ops on #channel:
%#/TRIGGER ADD %|-publics -actions -channels "#channel" -hasmode '-o' -stop
Send a mail to yourself every time a topic is changed:
%#/TRIGGER ADD %|-topics -command 'exec echo $\N changed topic of $\C to: $\M | mail you@somewhere.com -s topic'
%U%_Examples with -replace%_%U
%|Replace every occurence of shit with sh*t, case insensitive:
%#/TRIGGER ADD %|-all -nocase -regexp shit -replace sh*t
%|Strip all colorcodes from *!lamer@*:
%#/TRIGGER ADD %|-all -masks *!lamer@* -regexp '\x03\d?\d?(,\d\d?)?|\x02|\x1f|\x16|\x06' -replace ''
%|Never let *!bot1@foo.bar or *!bot2@foo.bar hilight you
%|(this works by cutting your nick in 2 different parts, 'myn' and 'ick' here)
%|you don't need to understand the -replace argument, just trust that it works if the 2 parts separately don't hilight:
%#/TRIGGER ADD %|-all masks '*!bot1@foo.bar *!bot2@foo.bar' -regexp '(myn)(ick)' -nocase -replace '$1\x02\x02$2'
%|Avoid being hilighted by !top10 in eggdrops with stats.mod (but show your nick in bold):
%#/TRIGGER ADD %|-publics -regexp '(Top.0\(.*\): 1.*)(my)(nick)' -replace '$1\x02$2\x02\x02$3\x02'
%|Convert a Windows-1252 Euro to an ISO-8859-15 Euro (same effect as euro.pl):
%#/TRIGGER ADD %|-regexp '\x80' -replace '\xA4'
%|Show tabs as spaces, not the inverted I (same effect as tab_stop.pl):
%#/TRIGGER ADD %|-all -regexp '\t' -replace ' '
