NAME

Arepa::Config - Arepa package database API

SYNOPSIS

my $config = Arepa::Config->new('path/to/config.yml');
my $config = Arepa::Config->new('path/to/config.yml',
                                builder_config_dir => 'path/to/builderconf');

my $pdb_path = $config->get_key('package_db');
my $repo_path = $config->get_key('repository:path');
if ($config->key_exists('optional:key')) {
    $value = $config->get_key('optional:key');
}

my @builder_names = $config->get_builders;
my %builder_config = $config->get_builder_config('some-builder');
my $value = $config->get_builder_config_key('some-builder', $key);

DESCRIPTION

This class allows easy access to the Arepa configuration. The configuration is divided in two parts: the basic configuration (a single YAML file) and the configuration for the builders (a YAML file for each builder). Typically you would pass a single path for the main configuration, and the builder configuration would be loaded from the directory builders inside the same parent directory as the main configuration file. However, if you want you can specify a custom directory to load the builder configuration from.

This is an example of the basic configuration file:

---
repository:
  path: /home/zoso/src/apt-web/test-repo/
upload_queue:
  path: /home/zoso/src/apt-web/incoming
package_db: /home/zoso/src/apt-web/package.db
web_ui:
  base_url: http://localhost
  template_dir: /home/zoso/src/apt-web/repo-tools-web/templates/
  user_file: /home/zoso/src/apt-web/repo-tools-web/users.yml

This is an example of a builder configuration file (say, squeeze32.yaml):

---
type: sbuild
architecture: i386
distribution: my-squeeze
other_distributions: [squeeze, unstable]

Usually this class is not used directly, but internally in Arepa::Repository or Arepa::BuilderFarm.

METHODS

new($path)

new($path, %options)

It creates a new configuration access object for the configuration file in the given $path. The only valid option is builder_config_dir, the path where the builder configuration files are located.

key_exists($key)

Return true/false if the given configuration key is defined or not.

get_key($key)

Returns the value of the given $key in the configuration file. If it's not a top-level key, the subkeys must be separated by a colon (":"). If the key cannot be found, an exception is thrown.

get_builders

Returns an array of names of the defined builders.

get_builder_config($builder_name)

Returns a hash with the configuration of the given $builder_name. If no builder (or more than one) is found by that name, an exception is thrown.

get_builder_config_key($builder_name, $key)

Returns the value for the given configuration $key for the given $builder_name.
