Extract subroutines from a Perl script. OR: "Only perl can parse Perl." But can it help me to do so?
If you need to extract the exact source code, it may be quite difficult. If it is sufficient to get a functional equivalent, look into B::Deparse; from the docs:
$deparse = B::Deparse->new("-p", "-sC");
$body = $deparse->coderef2text(\&func);
and here's a specific example as a one-liner:
zen% perl -MB::Deparse -MCarp -wle 'print B::Deparse->new("-p","-sC"
See the rest of the docs for full details of the options available.
