Eggdrop users often like a script's functionality to work on only some of the channels the Eggdrop resides on. For example, an Eggdrop running a Tcl script that greets every user is nice on a small channel, but would quickly become annoying on a busy channel where users are joining every 30 seconds. There are two ways you can enable a script to work on only some channels the Eggdrop resides on.
User-defined Channel Flags (Preferred)
Adding a channel flag
From doc/tcl-commands.doc, you can use the setudef command:
setudef <flag/int/str> <name>
    Description: initializes a user defined channel flag, string or integer setting. You can use it like any other flag/setting. IMPORTANT: Don’t forget to reinitialize your flags/settings after a restart, or it’ll be lost.
This command creates a new flag setting that can be used via the
.chanset
command, and viewed via the
.chaninfo
command. To create a custom flag that a script can check, create it by adding the setudef command:
setudef flag myscript
This will add a flag that can be viewed, enabled or disabled via the partyline:
User defined channel flags:
     -myscript
As with any other Eggdrop channel flag, it can be enabled or disabled with the .chanset command:
.chanset #test +myscript
Successfully set modes { +myscript  } on #test.
[22:42:18] #-HQ# chanset #test +myscript 
.chaninfo #test
User defined channel flags:
     +myscript
Checking a channel flag
So now that you've added a channel flag that the user can interact with, how does a script use that information? The answer is the channel get Tcl command.
channel get <name> [setting]
    Returns: The value of the setting you specify. For flags, a value of 0 means it is disabled (-), and non-zero means enabled (+). If no setting is specified, a flat list of all available settings and their values will be returned.
To check if a flag is enabled for a flag, you would use:
channel get #test myscript
Or, perhaps a more useful example:
if [channel get #test myscript] {
  putserv "PRIVMSG #test :This is a message that is only sent if the myscript flag is enabled"
}
=== Example Tcl script ===
So now, let's write a simple greet script that can be turned on and off via the partyline for each channel:
<pre>
bind join * * greetNewUser
setudef flag greetScript
proc greetNewUser{nick user hand chan} {
  if {[channel get $chan greetScript]} {
    putserv "PRIVMSG $chan :Hello $nick, welcome to $chan!"
  }
}
