# NAME

Module::Loaded - mark modules as loaded or unloaded

# SYNOPSIS

        use Module::Loaded;

        $bool = mark_as_loaded('Foo');   # Foo.pm is now marked as loaded
        $loc  = is_loaded('Foo');        # location of Foo.pm set to the
                                         # loaders location
        eval "require 'Foo'";            # is now a no-op

        $bool = mark_as_unloaded('Foo'); # Foo.pm no longer marked as loaded
        eval "require 'Foo'";            # Will try to find Foo.pm in @INC

# DESCRIPTION

When testing applications, often you find yourself needing to provide functionality in your test environment that would usually be provided by external modules. Rather than munging the `%INC` by hand to mark these external modules as loaded, so they are not attempted to be loaded by perl, this module offers you a very simple way to mark modules as loaded and/or unloaded.

# FUNCTIONS

## $bool = mark_as_loaded( PACKAGE );

Marks the package as loaded to perl. `PACKAGE` can be a bareword or string.

If the module is already loaded, `mark_as_loaded` will carp about this and tell you from where the `PACKAGE` has been loaded already.

## $bool = mark_as_unloaded( PACKAGE );

Marks the package as unloaded to perl, which is the exact opposite of `mark_as_loaded`. `PACKAGE` can be a bareword or string.

If the module is already unloaded, `mark_as_unloaded` will carp about this and tell you the `PACKAGE` has been unloaded already.

## $loc = is_loaded( PACKAGE );

`is_loaded` tells you if `PACKAGE` has been marked as loaded yet. `PACKAGE` can be a bareword or string.

It returns falls if `PACKAGE` has not been loaded yet and the location from where it is said to be loaded on success.
