countdown.tcl

[CrazyCat]

You try to call a proc designed for a public command with a cron, it can't work, the proc won't get the required arguments.
You can try to replace your bind with the following one and it associated proc:

tclcopier

bind cron - "00 */4 * * *" cron_countdown
proc cron_countdown {min hour day month dow} {
   pub_countdown $::botnick "bot@127.0.0.1" $::botnick countdown_chans ""
}

This will work if countdown_chans has only one channel, if you want to use several ones, the proc must become:

tclcopier

proc cron_countdown {min hour day month dow} {
   foreach chan [split $::countdown_chans] {
      pub_countdown $::botnick "bot@127.0.0.1" $::botnick $chan ""
   }
}
