Redirecting Output

2002-12-27T00:13:08-04:00

Thanks for the quick reply! 'catch' is exactly what I was looking for. Here is the final code for anyone interested:

Code:

bind pub - !calc calcproc calc { nick uhost hand chan arg } {    if {[llength $arg]==0} {        return 0    }    if { [catch { set result [expr $arg]} err] } {        putserv "PRIVMSG $chan :$nick: Error:  $err"    } else {        putserv "PRIVMSG $chan :$nick: $result"    }}

thanks again,
acm

You should probably catch it, with something similiar to this (correct me if im wrong guys)

Code:

if {[catch blah blah e]} {putserv "etc etc"return}

Make sure to use catch to execute the calc string, otherwise it wont do any good. You could also just check if the operation is "/" and then if the number is not zero, put I'll let you try out this way first.

Redirecting Output

I wrote a little !calc script:

Code:

bind pub - !calc calcproc calc { nick uhost hand chan arg } {    if {[llength $arg]==0} {        return 0    }    set result [expr $arg]    putserv "PRIVMSG $chan :$nick: $result"}

It works exactly how I want it to, except when there are problems with the arguments. Example:

!calc 4 / 0

This returns the following in botnet (and nothing to the channel):

Tcl error [calc]: divide by zero

I would like this to print out to the channel instead. Is it possible to do output redirection like this?
