NAME

Otogiri::Plugin - make Otogiri to pluggable

SYNOPSIS

    use Otogiri;
    use Otogiri::Plugin;
    my $db = Otogiri->new( connect_info => ["dbi:SQLite:dbname=$dbfile", '', ''] );
    Otogiri->load_plugin('UsefulPlugin');
    $db->useful_method; #derived from UsefulPlugin

DESCRIPTION

Otogiri::Plugin provides Teng-like plugin function to Otogiri.

METHODS

$class->load_plugin($plugin_name, $opt)

Load plugin to Otogiri or subclass. This method is exported to Otogiri or it's subclass(not to Otogiri::Plugin namespace). By default, plugins are loaded from Otorigi::Plugin::$plugin_name namespace. If '+' is specified before $plugin_name, plugins are loaded specified package name. for example,

    Otogiri->load_plugin('UsefulPlugin');          # loads Otogiri::Plugin::UsefulPlugin
    Otogiri->load_plugin('+Some::Useful::Plugin'); # loads Some::Useful::Plugin

You can use alias method name like this,

    Otogiri->load_plugin('UsefulPlugin', { 
        alias => {
            very_useful_method_but_has_so_long_name => 'very_useful_method', 
        }
    });

In this case, plugin provides very_useful_method_but_has_so_long_name, but you can access very_useful_method

HOW TO MAKE YOUR PLUGIN

To make Otogiri plugin is very simple. If you have experience to make Teng plugin, you can write also Otogiri plugin because making Otogiri plugin is almost same as making Teng plugin.

To make your plugin is only following two steps.

1. create package

If you will ship your plugin to CPAN, recommended package namespace is Otogiri::Plugin::. Or If you want to use your project(application)'s namespace, it is enable. See load_plugin() section.

    package Otogiri::Plugin::NewPlugin;
    use strict;
    use warnings;
    1;

2. add @EXPORT and implement method you want to provide as this plugin

    package Otogiri::Plugin::NewPlugin;
    use strict;
    use warnings;
    our @EXPORT = qw(useful_method);

    sub useful_method { #this method is exported to Otogiri as plugin
        my ($self, $param_href, $table_name) = @_;
        $self->_deflate_param($table_name, $param_href); # if you need to deflate
        ...
        my @rows = $rtn ? $self->_inflate_rows($table, @$rtn) : (); #if you need to inflate
        return @rows;
    }

    sub _private_method {
        my ($self, $param_href) = @_;
        # this method is not exported to Otogiri because it's not included in @EXPORT
        ...
    }
    1;
