Re^2: Machine-readable Current Version

in thread Machine-readable Current Version

I wanted to try the MetaCPAN::Client module so I ran cpanm and installed it. That was when I realized how many dependencies it has! This module and its dependencies consumed over 16MB of disk space and took over an hour to install. Please understand I have nothing against this module. I know it has many useful features and I realize these dependencies are needed for it to do all the things it does, but in my opinion it is a bit of overkill just to see the version number. You may want to consider using the $^V system variable to get the current version:
#!/usr/bin/perl use strict; use warnings; my $version = $^V; print "$version\n";
Produces the following output: v5.24.1

    Um, yes, but ...

    ... it returns the version of perl you are currently running, which might be very different from the most recently released Perl. Quoting the original posting:

    is there a site/URL that can be scraped to find what the most recent release is?

      Yep. My plan is basically to write a prove script that compares the two, and the result gets fed to a web dashboard as a 'pass/fail'.
