Simple, extensible Perl debugger

A debugger is a computer program that is used to debug other programs. Develebug is a simple, extensible Perl debugger with a clean API. Using this module, you may easily write a Perl debugger to debug your programs. Alternatively, it comes with an interactive debugger, ebug.

perl5db.pl, Perl’s current debugger is currently 2,600 lines of magic and special cases. The code is nearly unreadable fixing bugs and adding new features is fraught with difficulties. The debugger has no test suite which has caused breakage with changes that couldn’t be properly tested. It will also not debug regexes. Develebug is aimed at fixing these problems and delivering a replacement debugger which provides a well-tested simple programmatic interface to debugging programs. This makes it easier to build debuggers on top of Develebug, be they console-, curses-, GUI- or Ajax-based.

There are currently two user interfaces to Develdebug, ebug and ebug_http. ebug is a console-based interface to debugging programs, much like perl5db.pl. ebug_http is an innovative web-based interface to debugging programs.
