ptkdb is a debugger for perl that uses Perl/Tk for a user interface.
Features include:
Hot Variable Inspection
Breakpoint Control Panel
Expression List
Subroutine Tree
To debug a script using ptkdb invoke perl like this:
perl -d:ptkdb myscript.pl
ptkdb can easily be used to debug CGI scripts if your web server box is
capable of running Perl/Tk applications. Just change the shebang line of your
scripts to:
#! /usr/bin/perl -w -d:ptkdb
