Re: Finding Module Versions - How Would You Do It?

[kcott]

G'day Tommy,

With older versions of Perl, I used to do:

$ perl -e 'use Test::More; print $Test::More::VERSION, "\n"'
0.98

With newer versions of Perl, I now use the slightly shorter:

$ perl -E 'use Test::More; say $Test::More::VERSION'
0.98

And to automate, using a selection of modules from your list, you could do something like:

$ module_list='Test::More English File::Find Test::Perl::Critic'
$ for i in $module_list; do
> echo $i
> eval "echo \`perl -E 'use $i; say \$$i::VERSION'\`"
> done
Test::More
0.98
English
1.04
File::Find
1.19
Test::Perl::Critic
1.02

I have this bash function in my .bashrc:

pmv () { perl -M$1 -e "print \$$1::VERSION . qq/\n/;"; }

which is based along similar lines and works for me. It is invoked like this:

pmv Test::More

Simple, but effective.

Have you two even read the post at all? This is exactly what Tommy doesn’t want to do for reasons explained there.
