    MyApp::Foo becomes myapp_foo


    MyApp::Controller::Foo::Bar becomes MyApp
    My::App::Controller::Foo::Bar becomes My::App


    MyApp::Controller::Foo::Bar becomes MyApp::Controller
    My::App::Controller::Foo::Bar becomes My::App::Controller


    MyApp::Controller::Foo::Bar becomes Controller::Foo::Bar


Returns the environment name for class.

    MyApp becomes MYAPP
    My::App becomes MY_APP

class2prefix( $class, $case );

Returns the uri prefix for a class. If case is false the prefix is converted to lowercase.

    My::App::Controller::Foo::Bar becomes foo/bar

class2tempdir( $class [, $create ] );

Returns a tempdir for a class. If create is true it will try to create the path.

    My::App becomes /tmp/my/app
    My::App::Controller::Foo::Bar becomes /tmp/my/app/c/foo/bar


Returns home directory for given class.

prefix($class, $name);

Returns a prefixed action.

    MyApp::Controller::Foo::Bar, yada becomes foo/bar/yada


Returns an HTTP::Request object for a uri.

ensure_class_loaded($class_name, \%opts)

Loads the class unless it already has been loaded.

If $opts{ignore_loaded} is true always tries the require whether the package already exists or not. Only pass this if you're either (a) sure you know the file exists on disk or (b) have code to catch the file not found exception that will result if it doesn't.

merge_hashes($hashref, $hashref)

Base code to recursively merge two hashes together with right-hand precedence.

env_value($class, $key)

Checks for and returns an environment value. For instance, if $key is 'home', then this method will check for and return the first value it finds, looking at $ENV{MYAPP_HOME} and $ENV{CATALYST_HOME}.


Try to guess terminal width to use with formatting of debug output

All you need to get this work, is:

1) Install Term::Size::Any, or

2) Export $COLUMNS from your shell.

(Warning to bash users: 'echo $COLUMNS' may be showing you the bash variable, not $ENV{COLUMNS}. 'export COLUMNS=$COLUMNS' and you should see that 'env' now lists COLUMNS.)

As last resort, default value of 80 chars will be used.


Method which adds the namespace for plugins and actions.


  # will load Catalyst::Plugin::MyPlugin
