perl debug

[Duffs]

Hi,

Does anybody know if there is a 'set -x' equivalent for perl?

After some googling the nearest I got was the suggestion to include:

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

This however is not as effective/informative as I would like. Surely there has to be another means of debugging a perl script?

-d option

man perldebug

Also, use

use Data::Dumper;

It's great for dumping variables!

Almost right.

-d does not allow non-interactive tracing

Devel::Trace does :) and it uses the -d interface:


lt09:/home/merijn 103 > perl -d:Trace -le 'for (1..3) {' -e 'print' -e '}'
>> -e:1: for (1..3) {

>> -e:2: print

1
>> -e:2: print

2
>> -e:2: print

3
