Re: call tree analysis using perl

in reply to call tree analysis using perl

Given how fragile and experimental Devel::Calltree is reported to be, and assuming that your data isn't any more complex than what you're showing (large assumption, I know), you could try unwrapping them yourself.

#!/usr/bin/perl -w
use warnings;
use strict;

my ($tag, %list);
while (<DATA>){
    next unless /./;

    if (/^(\w+)/){
        $tag = $1;
        next;
    }

    if (/^-- (\w+)/){
        push @{$list{$tag}}, $1;
    }
}

for my $type (@{$list{main}}){
    if ($list{$type}){
        for (@{$list{$type}}){
            print "main $type $_\n";
        }
    }
    else {
        print "main $type\n";
    }
}

__END__

Hi oko1 , wonderful dude, I tried the above snippet and it works perfect. but i got a doubt , i tried expanding the function names and still i got only three functions at a time.. `display -- audit -- bass elucent -- audit -- check main -- display -- elucent -- audit -- check audit -- hi_oko1 Output: So the new output should be like this: main display audit hi_oko1 main display bass main elucent audit hi_oko1 main elucent check main audit But still im getting the same o/p:- main display audit main display bass main elucent audit main elucent check main audit hi_oko1` [download]	[reply] [d/l]

As there is no `Data` in that script, I suppose you wrote `while (<Data>){` [download] This is not the same as `while (<DATA>){` because Perl is case-sensitive.	[reply] [d/l] [select]
