NAME

Config::YAML::Modern - Modern YAML-based config loader from file or directory.

VERSION

Version 0.36

SYNOPSIS

Config::YAML::Modern created to get dial with yaml-based configuration.

Its possible to load single file, or all files in one directory (without recursion search).

Data from many files was be merged properly (almost), also filename was be converted to top-level hash keys.

Filename like 'file.data.yaml' was be converted to { file => { data => $file_content } }.

Also module provide perfect dive() interface form Data::Diver.

It may be used like

my $file_content = $conf_object->dive(qw/file data/);

Simply usage for file load

use Config::YAML::Modern;

my $config = Config::YAML::Modern->new();

my $filename = 'test.yaml';

$config->load_file($filename);

my $data = $config->config();

More complicated for directory-based loading

my $config2 = Config::YAML::Modern->new( key_conversion => 'ucfirst' );

my $directory = '/etc/my_app/';

# slurp all data to hashref
my $data2 = $config2->load_dir($directory)->config();

# but exist more sophisticated path
my @list_of_key = (qw/Model Message 0 author/);
my $data3 = $config2->dive(@list_of_key);

# $data3 == $data2->{Model}{Message}[0]{author}

SUBROUTINES/METHODS

new

new( [ list of args ] ) - create Config::YAML::Modern object and return it.

my $config = Config::YAML::Modern->new();

The options currently supported are:

  • merge_behavior behavior on merge data, see Hash::Merge docs.

    Available values are [LEFT_PRECEDENT, RIGHT_PRECEDENT, STORAGE_PRECEDENT, RETAINMENT_PRECEDENT], 'LEFT_PRECEDENT' by default.

  • file_suffix File suffix, used in search files in directory for matching. '.yaml' by default.

  • key_conversion Rule for conversion parts of filename to hash keys.

    Available values are [undef, uc, ucfirst, lc, lcfirst]. No conversion - 'undef' by default.

  • i_dont_use_suffix Set to true if you not use suffix on config files. Suffix is used by default - 'undef'.

  • __force_return_data If setted to true, methods: load_file(), load_dir(), add_hash(), add_file() and add_dir() returns dataset instead of $self, returned by default - 'undef'.

    !!! important - in this case loaded or added data are NOT BE STORED in object, use it well

  • ignore_empty_file If setted to true method:

    - load_file() will return or assign to object empty flat hash without created keys by file name - just {}.

- load_dir() will ignore empty files and not been add keys by names of empty files at all

- add_file() and add_dir() will ignore empty files and not use it in merge process

    By default empty files NOT ignored, value by default - 'undef'.

load_file

load_file($filename) - load data from yaml-contained file

$config->load_file($filename);

load_dir

load_dir($directory) - get files from directory (non-recursive), load data and merge it together

$config2->load_dir($directory);

add_hash

add_hash($hash_ref, $behavior? ) - add data to object from hash with $behavior resolution, or use default behavior.

my $data3 = $config2->add_hash( $hash_ref, 'RIGHT_PRECEDENT' );

Just wrapper ontop of "merge" in Hash::Merge

add_file

add_file($filename, $behavior? ) - add data to object from file with $behavior resolution, or use default behavior.

my $data3 = $config2->add_file( $filename3, 'RIGHT_PRECEDENT' );

add_dir

add_dir($dir_name, $behavior? ) - add data to object from directory with $behavior resolution, or use default behavior.

my $data3 = $config2->add_dir( $dir_name2, 'RETAINMENT_PRECEDENT' );

dive

dive(@list_of_key) - return data from object by @list_of_key patch resolution, return "undef" if path resolution wrong.

my $data3 = $config2->dive(@list_of_key);

Just wrapper ontop of "Dive" in Data::Diver

dive_die

dive_die(@list_of_key) - return data from object by @list_of_key patch resolution, and do "die" if path resolution wrong.

my $data3 = $config2->dive_die(@list_of_key);

Just wrapper ontop of "DiveDie" in Data::Diver

config

config() - return all config data from object

my $data = $config->config();

DEPRECATED METHODS

The old module interface is still available, but its use is discouraged. It will eventually be removed from the module.

file_load

file_load($filename) - load data from yaml-contained file

$config->file_load($filename);

dir_load

dir_load($directory) - get files from directory, load data and merge it together

$config2->dir_load($directory);

hash_add

hash_add($hash_ref, $behavior? ) - add data to object from hash with $behavior resolution, or use default behavior.

my $data3 = $config2->hash_add( $hash_ref, 'RIGHT_PRECEDENT' );

Just wrapper ontop of "merge" in Hash::Merge

file_add

file_add($filename, $behavior? ) - add data to object from file with $behavior resolution, or use default behavior.

my $data3 = $config2->file_add( $filename3, 'RIGHT_PRECEDENT' );

dir_add

file_add($dir_name, $behavior? ) - add data to object from directory with $behavior resolution, or use default behavior.

my $data3 = $config2->dir_add( $dir_name2, 'RETAINMENT_PRECEDENT' );

EXPORT

Nothing by default.
