=head1 NAME

CatalystX::InjectModule - injects modules containing components, plugins, config, lib, templates ...

=head1 VERSION

version 0.16

This module is at EXPERIMENTAL stage, so use with caution.

=head1 SYNOPSIS


    use Catalyst qw/
        ConfigLoader
        +CatalystX::InjectModule
    /;

    # myapp.yml
    CatalystX::InjectModule:
      path:
        - t/share/modulesX
        - t/share/modules
      modules:
        - Ax
        - A

    # Each module must have at least one file cxmi_config.yml
    name: Bx
    version: 2
    deps:
      - Cx == 2
      - Ex
    catalyst_plugins:
      - Static::Simple
      - +CatalystX::SimpleLogin


Ce plugin permet d'injecter des 'modules CatalystX::InjectModule' (CI) dans une application Catalyst.

Qu'est ce qu'un module CI ?

Un module CI est défini par son nom et sa version. Si d'autres informations sont enregistrées dans son fichier de configuration 'cxmi_config.yml' elles sont fusionnées avec la config de l'application Catalyst.

Un module CI peut être dépendant d'autres modules CI. Le mot-clé 'deps' est alors utilisé pour les définir :

    deps:
      - OtherModule
      - Another

Un module CI peut être constitué de :

    - librairies Perl : Elles sont dans ce cas ajoutées aux chemins de recherche des librairies (@INC)

    - composants Catalyst ( Model, View, controller ) : Ils sont injectés dans l'application Catalyst

    - plugins Catalyst ( via le mot clé catalyst_plugins du fichier de configuration du module) : Ils sont injectés dans l'application.

    - Fichiers tt dans root/src et root/lib ( Template Toolkit )

    - Un fichier a son nom comportant une fonction 'install' qui sera exécutée lors du chargement. L'installation ne peut se faire qu'une seule fois. Pour réinstaller un Module CI il faut au préalable déinstaller le module.
