I have a project where I need to be able to automatically find all the dependancies of a script. I have a one liner that finds all the modules that a script depends on that looks like this:
perl -e 'do $ARGV[0]; print "$_\n" for values %INC' test.pl
The problem with this is that when I "do" the file name it executes the file, which sometimes is not what I want to happen. I have a clunky way of getting all the module dependancies without running the script that works like this :
#!/usr/bin/perl use strict; my $file=shift; local $/=undef; open IN, $file; my $text=<IN>; $text.="\n".q( CHECK{ foreach my $module (values %INC) { print $module."\n"; } } ); open JUNK,">.this_is_some_junk"; print JUNK $text; close JUNK; system "perl -c .this_is_some_junk"; unlink ".this_is_some_junk";
I think that there must be a better way. Any ideas?
