Module::Loaded - mark modules as loaded or unloaded
$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
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.
$bool = mark_as_loaded( PACKAGE );
Marks the package as loaded to perl. "PACKAGE" can be a bareword or
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.
