Vorläufig noch das alte Abstract von der YAPC:EU2012 in Englisch.

Deutsches update mit neuen Features folgt.


In comparison to many other script languages the Perl project lacks a convenient interactive shell which is available out of the box.

For instance Rubys "irb" has many advantages over using Perl's debugger started with "perl -de0".

We will show an approach to extend/reconfigure the perldebugger in a way to achieve:

- a REPL feeling by dumping the return values automatically without needing to prepend an p or x command.

- automatic multiline support including indentation (i.e. w/o needing to append "\\")

- importing shell commands for everyday use of commands like "ls" or "cd".
