NAME

Module::Locate - locate modules in the same fashion as require and use

SYNOPSIS

use Module::Locate qw/ locate get_source /;

plugin( locate "This::Module" );
munge(  get_source "Another::Module::Here" );

if(locate "Some::Module") {
  ## do stuff
}

DESCRIPTION

Using locate(), return the path that require would find for a given module (it can also return a filehandle if a reference in @INC has been used). This means you can test for the existence, or find the path for, modules without having to evaluate the code they contain.

FUNCTIONS

import

Given function names, the appropriate functions will be exported into the callers package.

If Global => BOOL is passed in, then the all the results for module searche i.e using locate, will also be stored in %INC, just like require. This is on by default.

If Cache => BOOL is passed in, then every subsequent search for a module will just use the path stored in %INC, as opposed to performing another search. This is off by default.

locate

Given a module (in standard perl bareword format) locate the path of the module. If called in a scalar context the first path found will be returned, if called in a list context a list of paths where the module was found. Also, if references have been placed in @INC then a filehandle will be returned, as defined in the require documentation.

get_source

When provided with a package name, retrieve the source of the .pm that is found.

acts_like_fh

Given a scalar, check if it behaves like a filehandle. Firstly it checks if it is a bareword filehandle, then if it inherits from IO::Handle and lastly if it overloads the <> operator. If this is missing any other standard filehandle behaviour, please send me an e-mail.
