MooX::ConfigFromFile::Role - Moo eXtension for initializing objects from config file
This role adds a initializing sub around BUILDARGS and puts all what could read from config files into the hash which will be used to construct the final object.
While it does that, it internally calls it's own _build_* methods (_build_config_prefix, _build_config_files and _build_loaded_config) unless the appropriate attributes are already in
This role uses following attributes which might be suitable customized by overloading the appropriate builder or pass defaults in construction arguments.
This attribute is a string and defaults to FindBin's
$Script. It's interpreted as the basename of the config file name to use.
This attribute is an array of strings and defaults to
<[ config_prefix ]>.
This attribute is a string and contains the character which is used building config_prefix_map from config_prefixes.
This attribute is an array of strings containing all config-prefixes joint together
($0, $0.$1, $0.$1.$2, ...) using config_prefix_map_separator.
This attribute contains a cross-product of config_prefix_map and config_extensions. Both are concatenated using the shell wildcard '*'.
This attribute is consumed from MooX::File::ConfigDir. It might not be smart to override - but possible. Use with caution.
This attribute defaults to list of extensions from Config::Any.
This attribute contains the list of existing files in config_dirs matching config_prefix . config_extensions. Search is operated by File::Find::Rule.
This attribute contains the config as loaded from file system in an array of
filename => \%content.
This attribute contains the loaded files from filesystem sorted by string in the same format as raw_loaded_config (array of
filename => \%content).
The default algorithm is sorted by filename (mind:
'-' < '.').
This attribute contains the config loaded and transformed while constructing the instance. Construction is done from sorted_loaded_config, ignoring the filename part.
For classes set up using
use MooX::ConfigFromFile config_singleton = 1;
this attribute is cached from the very first construction and fed by overwritten builder. The content of this attribute is passed to lower BUILDARGS.

Toby Inkster suggested to rely on BUILDARGS instead of intercepting object creation with nasty hacks. He also taught me a bit more how Moo(se) works.
