MooX::ConfigFromFile(3) User Contributed Perl Documentation MooX::ConfigFromFile(3)
 

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

   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

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_prefixes"
Default for "config_prefixes" in MooX::ConfigFromFile::Role. Ensure when use this flag together with MooX::Cmd to load "MooX::ConfigFromFile" before "MooX::Cmd".
"config_prefix_map_separator"
Default for "config_prefix_map_separator" in MooX::ConfigFromFile::Role.
  package Foo;
  # apply role MooX::ConfigFromFile::Role and override default for
  # attribute config_prefix_map_separator
  use MooX::ConfigFromFile config_prefix_map_separator => "~";
  ...
    
"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!
  package Foo;
  use MooX::ConfigFromFile config_dirs => [qw(/opt/foo/etc /home/alfred/area/foo/etc)];
  ...
    
"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.
  package Foo;
  # apply role MooX::ConfigFromFile::Role and override default for
  # attribute config_identifier - means to look e.g. in /etc/foo/
  use MooX::ConfigFromFile config_identifier => "foo";
  ...
    
"config_hashmergeloaded"
Consumes role MooX::ConfigFromFile::Role::HashMergeLoaded directly after MooX::ConfigFromFile::Role has been consumed.
