.SH "NAME"
CatalystX::Component::Traits \- Automatic Trait Loading and Resolution for Catalyst Components
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 2
\&    package Catalyst::Model::SomeModel;
\&    with \*(AqCatalystX::Component::Traits\*(Aq;
\&
\&    package MyApp::Model::MyModel;
\&    use parent \*(AqCatalyst::Model::SomeModel\*(Aq;

\&        traits => [\*(AqSearchedForTrait\*(Aq, \*(Aq+Fully::Qualified::Trait\*(Aq]
\&    });
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Adds a \*(L"\s-1COMPONENT\*(R"\s0 in Catalyst::Component method to your Catalyst component
base class that reads the optional \f(CW\*(C`traits\*(C'\fR parameter from app and component
config and instantiates the component subclass with those traits using
\&\*(L"new_with_traits\*(R" in MooseX::Traits from MooseX::Traits::Pluggable.
.SH "TRAIT SEARCH"
.IX Header "TRAIT SEARCH"
Trait names qualified with a \f(CW\*(C`+\*(C'\fR are taken to be full package names.
.PP
Unqualified names are searched for, using the algorithm described below.
.SS "\s-1EXAMPLE\s0"
.IX Subsection "EXAMPLE"
Suppose your inheritance hierarchy is:
.PP
.Vb 5
\&    MyApp::Model::MyModel
\&    Catalyst::Model::CatModel
\&    Catalyst::Model
\&    Catalyst::Component
\&    Moose::Object
.Ve
.PP
The configuration is:
.PP
.Vb 1
\&    traits => [\*(AqFoo\*(Aq]
.Ve
.PP
The package search order for \f(CW\*(C`Foo\*(C'\fR will be:
.PP
.Vb 2
\&    MyApp::TraitFor::Model::CatModel::Foo
\&    Catalyst::TraitFor::Model::CatModel::Foo
.Ve
.SS "A \s-1MORE PATHOLOGICAL EXAMPLE\s0"
.IX Subsection "A MORE PATHOLOGICAL EXAMPLE"
For:
.PP
.Vb 6
\&    My::App::Controller::AController
\&    CatalystX::Something::ControllerBase::SomeController
\&    Catalyst::Controller
\&    Catalyst::Model
\&    Catalyst::Component
\&    Moose::Object
.Ve
.PP
With:
.PP
.Vb 1
\&    traits => [\*(AqFoo\*(Aq]
.Ve
.PP
Search order for \f(CW\*(C`Foo\*(C'\fR will be:
.PP
.Vb 2
\&    My::App::TraitFor::Controller::SomeController::Foo
\&    CatalystX::Something::TraitFor::Controller::SomeController::Foo
.Ve
.PP
The \f(CW\*(C`Base\*(C'\fR after (M|V|C) is automatically removed.
.SH "TRAIT MERGING"
.IX Header "TRAIT MERGING"
Traits from component class config and app config are automatically merged if
you set the \f(CW\*(C`_trait_merge\*(C'\fR attribute default, e.g.:
.PP
.Vb 1
\&    has \*(Aq+_trait_merge\*(Aq => (default => 1);
.Ve
.PP
You can remove component class config traits by prefixing their names with a
\&\f(CW\*(C`\-\*(C'\fR in the app config traits.
.PP
For example:
.PP
.Vb 3
\&    package Catalyst::Model::Foo;
\&    has \*(Aq+_trait_merge\*(Aq => (default => 1);
\&    _\|_PACKAGE_\|_\->config\->{traits} = [qw/Foo Bar/];
\&
\&    package MyApp;
\&    _\|_PACKAGE_\|_\->config\->{\*(AqModel::Foo\*(Aq}{traits} = [qw/\-Foo Baz/];
.Ve
.PP
Will load the traits:
.PP
.Vb 1
\&    Bar Baz
.Ve
