You want to use the global variable inside the procedure but you're using it as a local variable (belonging to the proc's level), using :: indicates that the variable is in the global namespace. You can add 'global channels' line in your proc and normally use $channels(output) instead.

oops, indeed forgot to replace one var name, fixed

edit: okay, it's workig now, due to your hint of adding the ::

but what does that do exactly? :p

Tcl error [pub:command]: can't read "prechan(output)": no such variable

In the code you've posted, there's no prechan array at all. I guess you've changed the names of the variables; your 'channels' array is not global in the validchan proc, so use $::channels(output) instead.

i'll change the name of the proc to checkchan
i'm not removing the proc because the bot doesn't have to react on the command on every channel it is in, only on channels specified in the var

what do you think is causing the problem?

thanks for your help!

delete

Code:

proc validchan { chan } {  foreach c $channels(output) {    if { $chan == $c } { return 1 }    else { return 0 }  }}

I don't see the use of this check (validchan) anyway, the bot is already on it when it saw the request.

Edit: After reading your post again, I noticed that the error you posted has nothing to do with the code you posted.

However, I suggest you change the name of your proc [validchan] since that is an Eggdrop Tcl command and may cause problems with other scripts.

Hi all,

I get the following error message:

Code:

Tcl error [pub:command]: can't read "channels(output)": no such variable

when I type !command while i'm in channel #output, how can I solve this problem?

Thanks in advance!

Code:

set channels(output) "#output #output2"set channels(output) [ split $channels(output) ]bind pub -|- "!command" pub:commandproc pub:command { nick uhost hand chan args } {  if { [ validchan $chan ] } {    putquick "privmsg $chan :you called?"  }}proc validchan { chan } {  foreach c $channels(output) {    if { $chan == $c } { return 1 }    else { return 0 }  }}

Code:
