NAME recommended - Load a recommended module and don't die if it doesn't exist VERSION version 0.001 SYNOPSIS use recommended 'Foo::Bar', { 'Bar::Baz' => '1.23', 'Wibble' => '0.14', }; if ( recommended->has( 'Foo::Bar' ) ) { # do something with Foo::Bar } # default version required if ( recommended->has( 'Wibble' ) ) { # do something with Wibble if >= version 0.14 } # custom version required if ( recommended->has( 'Wibble', '0.10' ) ) { # do something with Wibble if >= version 0.10 } DESCRIPTION This module tries to load recommended modules of particular minimum versions and provides means to check if they are loaded. It is a thin veneer around Module::Runtime. The major benefit over using Module::Runtime directly is that this allows you to self-document your recommended modules at the top of your code, while still loading them on demand elsewhere. USAGE import use recommended 'Foo::Bar', { 'Bar::Baz' => '1.23', 'Wibble' => '0.14', }; Scalar import arguments are treated as module names with a minimum required version of zero. Hash references are treated as module/minimum-version pairs. If you repeat, the later minimum version overwrites the earlier one. The list of modules and versions are kept separate for each calling package. has recommended->has( $module ); recommended->has( $module, $alt_minimum_version ); The "has" method takes a module name and optional alternative minimum version requirement and returns true if the following conditions are met: * the module was recommended (via "use recommended") * the module can be loaded * the module meets the default or alternate minimum version Otherwise, it returns false. The module is loaded without invoking the module's "import" method, as running import on an optional module at runtime is just weird.
