Devel::Trepan -- A new Perl debugger


A modular, testable gdb-like debugger in the style of the Ruby trepanning debuggers.

It supports syntax highlighting via Syntax::Highlight::Perl::Improved, a command completion (and history) via GNU ReadLine via Term::ReadLine::Perl or Term::ReadLine::Gnu, and interactive shell support via Psh or Devel::REPL.


From a shell:

    bash$ [trepan-opts] perl-program [perl-program-opts]

Or for those who prefer the traditional Perlish way:

    bash$ perl -d:Trepan perl-program [perl-program-opts]

Calling the debugger from inside your Perl program using Joshua ben Jore's Enbugger:

        # This needs to be done once and could even be in some sort of 
        # conditional code
        require Enbugger; Enbugger->load_debugger( 'trepan' );

        # work, work, work...
        # Oops! there was an error! Enable the debugger now!
        Enbugger->stop;  # or Enbugger->stop if ...
