6 MooX::ConfigFromFile::Role - Moo eXtension for initializing objects
7 from config file
8
10 This role adds a initializing sub around BUILDARGS and puts all what
11 could read from config files into the hash which will be used to
12 construct the final object.
13
14 While it does that, it internally calls it's own _build_* methods
15 (_build_config_prefix, _build_config_files and _build_loaded_config)
16 unless the appropriate attributes are already in $params.
17
19 This role uses following attributes which might be suitable customized
20 by overloading the appropriate builder or pass defaults in construction
21 arguments.
22
23 Be sure to read "ATTRIBUTES" in MooX::File::ConfigDir, especially
24 "config_identifier" in MooX::File::ConfigDir to understand how the
25 "config_dirs" are build.
26
27 When you miss a directory - see "plug_dir_source" in File::ConfigDir
28 and File::ConfigDir::Plack.
29
30 config_prefix
31 This attribute is a string and defaults to FindBin's $Script. It's
32 interpreted as the basename of the config file name to use.
33
34 config_prefixes
35 This attribute is an array of strings and defaults to "<[ config_prefix
36 ]">.
37
38 config_prefix_map_separator
39 This attribute is a string and contains the character which is used
40 building config_prefix_map from config_prefixes.
41
42 config_prefix_map
43 This attribute is an array of strings containing all config-prefixes
44 joint together "($0, $0.$1, $0.$1.$2, ...)" using
45 config_prefix_map_separator.
46
47 config_files_pattern
48 This attribute contains a cross-product of config_prefix_map and
49 config_extensions. Both are concatenated using the shell wildcard '*'.
50
51 config_dirs
52 This attribute is consumed from MooX::File::ConfigDir. It might not be
53 smart to override - but possible. Use with caution.
54
55 config_extensions
56 This attribute defaults to list of extensions from Config::Any.
57
58 config_files
59 This attribute contains the list of existing files in config_dirs
60 matching config_prefix . config_extensions. Search is operated by
61 File::Find::Rule.
62
63 raw_loaded_config
64 This attribute contains the config as loaded from file system in an
65 array of "filename => \%content".
66
67 sorted_loaded_config
68 This attribute contains the loaded files from filesystem sorted by
69 string in the same format as raw_loaded_config (array of "filename =>
70 \%content").
71
72 The default algorithm is sorted by filename (mind: '-' < '.').
73
74 loaded_config
75 This attribute contains the config loaded and transformed while
76 constructing the instance. Construction is done from
77 sorted_loaded_config, ignoring the filename part.
78
79 For classes set up using
80
81 use MooX::ConfigFromFile config_singleton = 1;
82
83 this attribute is cached from the very first construction and fed by
84 overwritten builder. The content of this attribute is passed to lower
85 BUILDARGS.

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