Config...tector(3pm)

💖 Config::Model::Itself::BackendDetector 💖

okay bestie, so this is Config::Model::Itself::BackendDetector — a 3pm manual page from the User Contributed Perl Documentation collection. she's a lil helper class whose entire job is detecting the read/write backends that config models can actually use. iconic behavior honestly. 🎀

---

✨ NAME ✨

Config::Model::Itself::BackendDetector — detects the available read/write backends that config models can use. that's it, that's the whole vibe check. 🦋

---

🌸 VERSION 🌸

version 2.027 — yes she's got a number and she's proud of it. 💅

---

⭐ SYNOPSIS ⭐

okay so first thing's first, bestie: this class is not something you just casually make yourself. you reference it in a configuration model, and Config::Model::Node is the one who creates it. periodt.

# this class should be referenced in a configuration model and
# created only by Config::Model::Node

my $model = Config::Model->new() ;

$model ->create_config_class
 (
  name => "Test",
  'element'
  => [
      'backend' => { type => 'leaf',
                     class => 'Config::Model::Itself::BackendDetector' ,
                     value_type => 'enum',
                     # specify backends built in Config::Model
                     choice => [qw/cds_file perl_file ini_file custom/],

                     help => {
                              cds_file => "file ...",
                              ini_file => "Ini file ...",
                              perl_file => "file  perl",
                              custom => "Custom format",
                             }
                   }
     ],
 );

 my $root = $model->instance(root_class_name => 'Test') -> config_root ;

 my $backend = $root->fetch_element('backend') ;

 my @choices = $backend->get_choice ;

see how it all flows? model → config class → instance → root → fetch the backend element → grab the choices. the whole glow-up pipeline. 🌈

💜 DESCRIPTION 💜

so here's the tea, bestie. 🍓

this class is derived from Config::Model::Value. she's built to be used inside an enum value, where the choices — like, the available backends — are made up of:

• the backends built in Config::Model, plus
• all the plugin backends — and by "all the plugin backends" we mean every single Config::Model::Backend::* class out there. all of them. the whole squad. 💀

and like, this module doesn't just sit there being cute (tho she does that too). she will:

1. detect the available plugin backends, and
2. query their pod documentation so she can serve up a lil contextual help for the config-model graphical editor. 🧚
