NAME

       MooX::ConfigFromFile - Moo eXtension for initializing objects from config file

SYNOPSIS

          package Role::Action;

          use Moo::Role;

          has operator => ( is => "ro" );

          package Action;

          use Moo;
          use MooX::ConfigFromFile; # imports the MooX::ConfigFromFile::Role

          with "Role::Action";

          sub operate { return say shift->operator; }

          package OtherAction;

          use Moo;

          with "Role::Action", "MooX::ConfigFromFile::Role";

          sub operate { return warn shift->operator; }

          package QuiteOtherOne;

          use Moo;

          # consumes the MooX::ConfigFromFile::Role but load config only once
          use MooX::ConfigFromFile config_singleton => 1;

          with "Role::Action";

          sub _build_config_prefix { "die" }

          sub operate { return die shift->operator; }

          package main;

          my $action = Action->new(); # tries to find a config file in config_dirs and loads it
          my $other = OtherAction->new( config_prefix => "warn" ); # use another config file
          my $quite_o = QuiteOtherOne->new(); # quite another way to have an individual config file

DESCRIPTION

       This module is intended to easy load initialization values for attributes on object construction from an
       appropriate config file. The building is done in MooX::ConfigFromFile::Role - using MooX::ConfigFromFile
       ensures the role is applied.

       For easier usage, with 0.004, several options can be passed via use resulting in default initializers for
       appropriate role attributes:

       "config_prefix"
           Default for "config_prefix" in MooX::ConfigFromFile::Role.

       "config_prefix_map_separator"
           Default for "config_prefix_map_separator" in MooX::ConfigFromFile::Role.

       "config_extensions"
           Default for "config_extensions" in MooX::ConfigFromFile::Role.

       "config_dirs"
           Default for "config_dirs" in MooX::ConfigFromFile::Role.  Same warning regarding modifying this
           attribute applies here: Possible, but use with caution!

       "config_files"
           Default for "config_files" in MooX::ConfigFromFile::Role.

           Reasonable when you want exactly one config file in development mode.  For production code it is
           highly recommended to override the builder.

       "config_singleton"
           Flag adding a wrapper around the builder of "loaded_config" in MooX::ConfigFromFile::Role to ensure a
           config is loaded only once per class. The per class restriction results from applicable modifiers per
           class (and singletons are per class).

       "config_identifier"
           Default for "config_identifier" in MooX::File::ConfigDir.
