Re: Setting break point for particular condition in the subroutine

[rjt]

It sounds like you want to insert the breakpoint at the if ($cmd =~ /INITIAL/i) line. Let's say that's line 123. Then, type:

b 123 $cmd =~ /INITIAL/i

Setting it to the subroutine entry is problematic because $cmd isn't set yet (or at least isn't set to a member of @commands. In addition to that, simply using /INITIAL/i as your condition would be running that regexp on $_, not $cmd.

See perldebug for more info.

This subroutine is called from other subroutine which is intern called from my perl script. So setting break point b 123 $cmd =~ /INITIAL/i throws error Line 118 not breakable. because my script does not have those many lines.

From the google docs I found the below statement b subname [condition] Can we use this in anyway?

[rjt]

Yes, that's why you need to figure out the actual line number. "123" was just an example. You can determine the line number with l Engine::_Execute ... lines that are breakable will show with a colon (:) after the line number in the debugger. Hence, if you see this:

100 sub Engine::Execute
101 {
102        
103:  foreach (@commands)
104   {
105:    $cmd = $_;
106:    if($cmd =~ /INITIAL/i)
107     {

... then you would type b 106 $cmd =~ /INITIAL/i

Again, these numbers are just examples. You need to determine the actual line number for yourself with l Engine::_Execute!

No and I already showed you two ways to solve this. Why didn't you try?
