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?
