in reply to perl tools

do you have recommentations about tools to develop perl programs and to debug perl programs

Now I admit I'm a professional linguist, but I understood this question right away. You're looking to see whether we have recommendations for developing and debugging Perl programs, verdad?

I use vim, the Perl Debugger (perl -d), strict, warnings, Data::Dumper, and Diagnostics.

You can use vim and EMACS as IDEs, but some people like Eclipse with the EPIC plugins.
