Module::Loaded
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.
