NAME

       Module::Path - get the full path to a locally installed module

SYNOPSIS

        use Module::Path 'module_path';

        $path = module_path('Test::More');
        if (defined($path)) {
          print "Test::More found at $path\n";
        } else {
          print "Danger Will Robinson!\n";
        }

DESCRIPTION

       Module::Path provides a single function, "module_path()", which will find where a module
       is installed locally.

       It works by looking in all the directories in @INC for an appropriately named file:

       ·   Foo::Bar becomes "Foo/Bar.pm", using the correct directory path separator for your
           operating system.

       ·   Iterate over @INC, ignoring any references (see "require" in "perlfunc" if you're
           surprised to hear that you might find references in @INC).

       ·   For each directory in @INC, append the partial path ("Foo/Bar.pm"), again using the
           correct directory path separator.  If the resulting file exists, return this path.

       ·   If no file was found, return "undef".

       I wrote this module because I couldn't find an alternative which dealt with the points
       listed above, and didn't pull in what seemed like too many dependencies to me.

       The distribution for "Module::Path" includes the "mpath" script, which lets you get the
       path for a module from the command-line:

        % mpath Module::Path

       The "module_path()" function will also cope if the module name includes ".pm"; this means
       you can pass a partial path, such as used as the keys in %INC:

         module_path('Test/More.pm') eq $INC{'Test/More.pm'}

       The above is the basis for one of the tests.

BUGS

       Obviously this only works where the module you're after has its own ".pm" file. If a file
       defines multiple packages, this won't work.

       This also won't find any modules that are being loaded in some special way, for example
       using a code reference in @INC, as described in "require" in "perlfunc".

SEE ALSO

       There are a number of other modules on CPAN which provide the same or similar
       functionality: App::whichpm, Class::Inspector, Module::Data, Module::Filename,
       Module::Finder, Module::Info, Module::Locate, Module::Mapper, Module::Metadata,
       Module::Runtime, Module::Util, and Path::ScanINC.

       I've written a review of all such modules that I'm aware of:

           <http://neilb.org/reviews/module-path.html>

       Module::Path was written to be fast, portable, and have a low number of core-only runtime
       dependencies. It you only want to look up the path to a module, it's a good choice.

       If you want more information, such as the module's version, what functions are provided,
       etc, then start by looking at Module::Info, Module::Metadata, and Class::Inspector.

       The following scripts can also give you the path: perldoc, whichpm
       <https://www.metacpan.org/module/whichpm>.
