Hi, I inherited 17 pages of perl code that, in my opinion, overuses global vars and has an overly complicated calling structure. The code works, but I'd like to refactor by reducing the number of global vars, and maybe simplify the calling structure as well.

Curently I'm going through a printout with pencil and marking up

Is there a way to do any of the above in an automated way, with tools (komodo?) or public domain .pl programs?

Would be nice to run something like

printGlobalVars.pl myscript.pl and it outputs file scoped "my" variables. (use strict and use warnings are on.)

Better yet would be if it indicated which functions used which global vars. With that and a calling structure, the task of refactoring is made significantly easier.

Thanks in advance!
