- Usage: ON [#|+|-|^|&|@]<event> [serial] [-|^]<match> [action]
- The ON command lets you set up actions which will occur when
- certains events happen. For example, you can create
- "personalized" away messages for different individuals,
- periodic actions that occur at specific times, just to name
- a few.
-
- Note that using ON JOIN and ON LEAVE to automatically greet
- people entering or leaving your channel is extremely poor
- etiquette. See /HELP ETIQUETTE.
-
- ON [mode]<event> [-|^]<match> [action]
- ON [mode]#<event> <serial number> [-|^]<match> [action]
-
- There are seven modes for each event. I've shown the # mode
- as a separate line because it requires a serial number.
- Different modes are specified by preceeding the event with
- one of the following characters:
- + Make event very noisy. It will display
- everything it does.
- - Make event quiet. It will not display any of
- it's actions.
- ^ Make event silent. Just like - above except it
- inhibits the normal event display as well. The
- only command that will cause output in this mode
- is the ECHO command. This can be used to redefine
- how event messages look.
- & Make the /ON local to only your own server. e.g.
- /on -&msg * echo One of mine
- Will echo "One of mine" ONLY when someone from my own
- current server sends me a message. If nothing matches
- in this list, then it will resort to the default ONs.
- Of if there was an /ON ^msg * echo :$0: $1- then it
- it will use that for anyone not on your server.
- @ This is like & except that it is exclusive to your
- server. It will NOT look at the default ONs if
- there is no match for your own server.
- # Allows you to assign a serial number to the specific
- <event> such that you can have multiple ON's trigger
- of one <event>. Further discussion of this below.
- Note this is a pound sign NOT a number. The serial
- number comes right after the <event>.
- If no character is specified, you will be warned upon activation
- of an event (this is somewhere between the + and - modes).
-
- The <match> parameter may be a single word, or a list of words
- surrounded by double quotes ("). The <match> determines
- specifically which events of the given <event> will cause
- the action to take place. The <match> may contain wildcards,
- and the specifics of the <match> parameter are dependant on
- the <event> type.
-
- If the <match> is preceeded by a -, that entry will be
- removed from the action list. For example:
- ON PUBLIC -BigCheese
- ON INVITE -"* +Har"
- The first will remove "BigCheese" from the PUBLIC list, the second will
- remove -"* +Har" from the INVITE list.
- You can remove all entries from a given event list by doing
- the following:
- ON <event> -
- For example:
- ON MSG -
- removes all entries in the ON MSG list.
-
- If the <match> is preceeded by a ^, then no action will be taken
- for a match for that event (this is used when you wish
- to exclude a nickname or list of nicknames from a larger
- wildcard match, see HELP ON FLOOD for an example).
-
- Added two new wildcards to the pattern matching system.
- '%' matches any sequence of characters except a space.
- '?' matches any single character.
- e.g. ON ^msg "bob % % blue" whatever
- would match a message from bob with two words and then the word
- 'blue'.
-
- The [action] parameter is that action that will occur when the
- specified event occurs which matches the given <match>.
- The action parameter is parsed by the command parse in exactly
- the same way as an IRCII alias is parsed, using the same inline
- variable expansions (See ALIAS). Also, depending on the
- event that is activated, there will be certain values passed
- as arguments to the action, just as if they were arguments to
- an alias. You may use the $0, $1, $2... etc variables to
- expand out these arguments. The arguments passed for each
- event are described in the individual help files for each event.
-
- Here are some examples:
- ON -MSG *cheese* /NOTICE $0 No Cheese Messages Please!
- Whenver a MSG is received from anyone with a nickname with
- cheese in it, a NOTICE will be sent out to that user. This
- action will generate no noticeable effect to you (it is marked
- as "quiet").
-
- ON MSG ^BigCheese
- If used with the first example above, this will prevent the
- action from being taken when a message is sent from BigCheese.
-
- Here is an example of how to redefine the way a
- message looks:
- ON ^MSG * /ECHO :$0: $1-
- All MSGs received from now on will look:
-
- :BigCheese: Hello!
- The same can be done with the other event types.
-
- IMPORTANT IMPORTANT: A full discussion of serial numbers is
- given in HELP ON serial_numbers as there is too
- much to place directly in this help file. Please read this one
- as it will help prevent collisions between different scripts.
-
- More examples are given for the individual event types.
