How could I find files that use certain modules in CPAN?

Question

Some modules on CPAN are excellently documented, others.... not so much, but it's usually easy to discern how to use a module via prior art (e.g modules/tests that used the module you're looking to use). I'm wondering what the best way is to find code that uses the code you're looking to use.

example

I want to use (maybe?) Dist::Zilla::App::Tester for something, but the author has elected not to write any documentation on how to use it, some I'm wondering what path of least resistance is to find code that already uses it.

please don't answer for this module

Answer 1

One option is to use Google Code Search (Google for that phrase for a link :) ); unioned with pure googling. Search for "use my::module::name" string.

If the module name is not something well-searchable (e.g. too many hits), may be combine with "

Answer 2

Try Google Code Search, trying to search for strings like "use Dist::Zilla::App::Tester" (quotes are important).

Answer 3

Use CPANTS - The CPAN Testing Service web site.

1. Search for the distribution
2. Click Other dists requiring this

Here is the page for Dist-Zilla

As an aside, you can always read the source by hitting the Source button on the top of the page on search.cpan.org. In this case, the package doesn't have much code to begin with. Also, many big modules these days have ::Cookbooks ::Manuals or ::Tutorials Dist-Zilla has one too

My guess is ::Tester just supplies the dzil test command through its test_dzil sub.
