CLI in debug?

regnad42 has asked for the wisdom of the Perl Monks concerning the following question:

I would like to know how to use the command line in PERL debug. I am using a 'Mintty' terminal window under 'Cygwin' and typically attempting to debug a script I have edited in VIM or somesuch. I then execute "perl -d codefile.pl". I do not ming retyping the small commands like

X variable

the problem is when I type a longer string, and make a small error, omission of a comma, or quote and want to hit up arrow then edir and fix it to attempt to get the correct result. What kind of 'CLI' does the debugger have to correct a previous line? Does one need to copy/paste or os there something more clever?

Hi regnad42, Please check out perldebug. You probably need to install something like `Term::ReadLine::Perl` from CPAN. Best, Jim πάντων χρημάτων μέτρον έστιν άνθρωπος.	[reply] [d/l]

You can also save your history for next time if you make a `~/.perldb` file and put something like this in it: `&parse_options("HistFile=$ENV{HOME}/.perldb.hist");` Garryq	[reply] [d/l] [select]

Not exactly answer to your question, just mentioning interesting module I learned from one lightning talk from Glasgow: Devel::PDB	[reply]
