3.11 Open Source Perl GUI Debuggers

A number of excellent Perl GUI debuggers provide graphical interfaces for diagnosing problems in your Perl programs. The quickest way to get up to speed on the general topic of debugging in Perl is to type the following commands:

$ perldoc perldebug
$ perldoc perldiag

Perlish people tend to use command-line debug programs with major sprinklings of print statements. But several open source GUI debugger programs are out there that you might want to consider. We've listed the best-known in Table 3-6.
