Wish list: define an exclusive set of search_dirs

[simonwistow]

Hi,

Thanks very much for your work on this! I've got a situation where I'd like to find modules which are only in a certain search path. I can add the dirs to search_dirs, but the issue is that I don't want all of @inc to be searched, because there may at times be some similarly named modules in @inc which I don't want to load. Would you be open to an option which would restrict the search to the supplied search_dirs rather than search_dirs + @inc? To be clear, I'm not asking to change the default behaviour of search_dirs, but to add this additional option.

My use case would be in the Stepford module: https://metacpan.org/source/DROLSKY/Stepford-0.002002/lib/Stepford/Planner.pm#L294

Thanks very much,

Olaf

I'll second this. I've been bitten by the current behaviour several times on various projects.

Most recently by test failures like http://www.cpantesters.org/cpan/report/9daf34ec-263f-11e4-926c-83eadfbfc7aa

The t/00-compile.t script is using Module::Pluggable to find all modules in the distro being tested so it can run require_ok() on them.

The problem is that Module::Pluggable is finding not only the modules in the distro but also all previously installed modules in that namespace.

I suggest a search_dirs_exclusively => 1 option to indicate that search_dirs is exclusive (like search_path is).

Note the 'BEHAVIOUR UNDER TEST ENVIRONMENT' doesn't apply because the tests get run like this:

$ make test
PERL_DL_NONLAZY=1 /Users/timbo/perl5/perlbrew/perls/perl-5.18.2/bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/*.t

In this case the blib module is not loaded so the magical blib/ behaviour isn't triggered.

Meanwhile, for my immediate needs, I've switched to https://metacpan.org/pod/Test::Compile

I have implemented this at #29
