NAME

Config::Model::Value::LayeredInclude - Include a sub layer configuration

VERSION

version 2.093

SYNOPSIS

# in a model declaration:
'element' => [
  'include' => {
    'class' => 'Config::Model::Value::LayeredInclude',

    # usual Config::Model::Value parameters
    'type' => 'leaf',
    'value_type' => 'uniline',
    'convert' => 'lc',
    'summary' => 'Include file for cascaded configuration',
    'description' => 'To support multiple variants of ...'
  },
]

DESCRIPTION

This class inherits from Config::Model::Value. It overrides _store to trigger a refresh of layered value when a value is changed. I.e. changing this value trigger a reload of the referred configuration file which values are used as default value. This class was designed to cope with multistrap configuration.

CAUTION

A configuration file can support 2 kinds of include:

  • Layered include which sets default values like multistrap or ssh. These includes are read-only.

  • Real includes like apache. In this cases modified configuration items can be written to included files.

This class works only with the first type
