48 When to match:
49 On which types of event to trigger:
50 These are simply specified by -name_of_the_type
51 The normal IRC event types are:
52 publics, %|privmsgs, pubactions, privactions, pubnotices, privnotices, joins, parts, quits, kicks, topics, invites, nick_changes, dcc_msgs, dcc_actions, dcc_ctcps
53 mode_channel: %|a mode on the (whole) channel (like +t, +i, +b)
54 mode_nick: %|a mode on someone in the channel (like +o, +v)
55 -all is an alias for all of those.
56 Additionally, there is:
57 rawin: %|raw text incoming from the server
58 send_command: %|commands you give to irssi
59 send_text: %|lines you type that aren't commands
60 beep: %|when irssi beeps
61 notify_join: %|someone in you notify list comes online
62 notify_part: %|someone in your notify list goes offline
63 notify_away: %|someone in your notify list goes away
64 notify_unaway: %|someone in your notify list goes unaway
65 notify_unidle: %|someone in your notify list stops idling
66
67 Filters (conditions) the event has to satisfy. They all take one parameter.
68 If you can give a list, seperate elements by space and use quotes around the list.
69 -pattern: %|The message must match the given pattern. ? and * can be used as wildcards
70 -regexp: %|The message must match the given regexp. (see man perlre)
71 %|if -nocase is given as an option, the regexp or pattern is matched case insensitive
72 -tags: %|The servertag must be in the given list of tags
73 -channels: %|The event must be in one of the given list of channels.
74 Examples: %|-channels '#chan1 #chan2' or -channels 'IRCNet/#channel'
75 %|-channels 'EFNet/' means every channel on EFNet and is the same as -tags 'EFNet'
76 -masks: %|The person who triggers it must match one of the given list of masks
77 -hasmode: %|The person who triggers it must have the give mode
78 Examples: %|'-o' means not opped, '+ov' means opped OR voiced, '-o&-v' means not opped AND not voiced
79 -hasflag: %|Only trigger if 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)
80 -other_masks
81 -other_hasmode
82 -other_hasflag: %|Same as above but for the victim for kicks or mode_nick.
83
84 What to do when it matches:
85 -command: Execute the given Irssi-command
86 %|You are able to use $1, $2 and so on generated by your regexp pattern.
87 %|For multiple commands ; (or $;) can be used as seperator
88 %|The following variables are also expanded:
89 $T: %|Server tag
90 $C: %|Channel name
91 $N: %|Nickname of the person who triggered this command
92 $A: %|His address (foo@bar.com),
93 $I: %|His ident (foo)
94 $H: %|His hostname (bar.com)
95 $M: %|The complete message
96 ${other}: %|The victim for kicks or mode_nick
97 ${mode_type}: %|The type ('+' or '-') for a mode_channel or mode_nick
98 ${mode_char}: %|The mode char ('o' for ops, 'b' for ban,...)
99 ${mode_arg} : %|The argument to the mode (if there is one)
100 %|$\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.
101
102 -replace: %|replaces the matching part with the given replacement in the event (requires a -regexp or -pattern)
103 -once: %|remove the trigger if it is triggered, so it only executes once and then is forgotten.
104 -stop: %|stops the signal. It won't get displayed by Irssi. Like /IGNORE
105 -debug: %|print some debugging info
106
107 Other options:
108 -disabled: %|Same as removing it, but keeps it in case you might need it later
109 -name: %|Give the trigger a name. You can refer to the trigger with this name in add/del/change commands
110
111 Examples:
112 Knockout people who do a !list:
113 /TRIGGER ADD %|-publics -channels "#channel1 #channel2" -nocase -regexp ^!list -command "KN $N This is not a warez channel!"
114 React to !echo commands from people who are +o in your friends-script:
115 /TRIGGER ADD %|-publics -regexp '^!echo (.*)' -hasflag '+o' -command 'say echo: $1'
116 Ignore all non-ops on #channel:
117 /TRIGGER ADD %|-publics -actions -channels "#channel" -hasmode '-o' -stop
118 Send a mail to yourself every time a topic is changed:
119 /TRIGGER ADD %|-topics -command 'exec echo $\N changed topic of $\C to: $\M | mail you@somewhere.com -s topic'
120
121
122 Examples with -replace:
123 %|Replace every occurence of shit with sh*t, case insensitive:
124 /TRIGGER ADD %|-all -nocase -regexp shit -replace sh*t
125 %|Strip all colorcodes from *!lamer@*:
126 /TRIGGER ADD %|-all -masks *!lamer@* -regexp '\x03\d?\d?(,\d\d?)?|\x02|\x1f|\x16|\x06' -replace ''
127 %|Never let *!bot1@foo.bar or *!bot2@foo.bar hilight you
128 %|(this works by cutting your nick in 2 different parts, 'myn' and 'ick' here)
129 %|you don't need to understand the -replace argument, just trust that it works if the 2 parts separately don't hilight:
130 /TRIGGER ADD %|-all masks '*!bot1@foo.bar *!bot2@foo.bar' -regexp '(myn)(ick)' -nocase -replace '$1\x02\x02$2'
131 %|Avoid being hilighted by !top10 in eggdrops with stats.mod (but show your nick in bold):
132 /TRIGGER ADD %|-publics -regexp '(Top.0\(.*\): 1.*)(my)(nick)' -replace '$1\x02$2\x02\x02$3\x02'
133 %|Convert a Windows-1252 Euro to an ISO-8859-15 Euro (same effect as euro.pl):
134 /TRIGGER ADD %|-regexp '\x80' -replace '\xA4'
135 %|Show tabs as spaces, not the inverted I (same effect as tab_stop.pl):
136 /TRIGGER ADD %|-all -regexp '\t' -replace ' '
