NAME

Banal::Config - A convenient wrapper around Config::General

SYNOPSIS

Quick summary of what the module does.

Perhaps a little code snippet.

use Banal::Config;

my $foo = Banal::Config->new(options=>{...}, switches=>{...});
...

EXPORT

None.

EXPORT_OK

None.

CLASS METHODS

get_default_config_term()

This "term" is in several places, such as : - for generating the name of the default command line switch possibly holding the config file path (used when no explicit config file path is given) - for generating the name of the default environment variable possibly holding the config file path (used when no explicit config file path is given) - for generating the default base name of the config file, which in turn is searched in several places (used when no explicit config file path is given) - for generating the default configuration context within the config file.

By default, returns the base name of the main program (script).

Can be overridden.

get_default_config_file_base_name()

The default base name of the configuration file, which will be searched in several places when trying to "guess" the config file path. This would only be needed when there is no explicit config file path given.

By default, simply calls "get_default_config_term()".

guess_config_file_path()

A call to this class method is made in order to build the default value of the "source" attribute, which will be used as the source path for the config file UNLESS one is explicetly given in the options argument to new().

The current implementation goes as follows: - It will first try suitable "switches". If one that designates the config fie path is defined, the that one will be return. By default, here are those switches that will be checked for definedness: cfg_[%TERM%] [%TERM%]_cfg cfg

		where TERM is obtained by a call to get_default_config_term()
		
- Then, we will see if there is an ENVIRONMENT variable, 
		[%TERM%]_CFG
		CFG_[%TERM%]
		
- or else, we will use as config, the first file that exists in the following list: 

		"./test/etc/" 	. 	$base_name . ".conf",	# this one is for testing purposes during "make test"
		"~/." 			.   $base_name . ".conf",
		"/etc/" 		.   $base_name . ".conf",
		"." 			.   $base_name . ".conf",

	where $base_name is obtained by a call to get_default_config_file_base_name()

get_possible_option_names_for_config_file_path

Used by guess_config_file_path() to check for command line switches.

Currently returns the list: cfg_[%TERM%] [%TERM%]_cfg cfg where TERM is obtained by a call to get_default_config_term()

get_possible_environment_variable_names_for_config_file_path

Used by guess_config_file_path() to check for ENVIRONMENT variables.

Currently returns the list: [%TERM%]_CFG CFG_[%TERM%]

where TERM is obtained by a call to get_default_config_term()

get_possible_config_file_paths()

Used by guess_config_file_path() after trying command line swictches and ENV variables. At this point (when everything else is exhausted), the first file that exists in the list returned by this function will be used as the config file.

Currently returns the list:

"./test/etc/" 	. 	$base_name . ".conf",	# this one is for testing purposes during "make test"
"~/." 			.   $base_name . ".conf",
"/etc/" 		.   $base_name . ".conf",
"." 			.   $base_name . ".conf",

where $base_name is obtained by a call to get_default_config_file_base_name()

METHODS

get_cfg()

Return the configuration value given by key (which may also be an ARRAY of path segments, or one long config key in path notation, or a mix).

If the value for the given key is not defined, it will be tried in outer contexts (in concentric circles) until it is found. This way, it is possible to set a value in an outer configuration context, and use it within.

A simple call to:

$self->grab_cfg(key=>[@_]);

grab_cfg()

Return the configuration value given by key (which may also be an ARRAY of path segments, or one long config key in path notation, or a mix).

If the value for the given key is not defined, it will be tried in outer contexts (in concentric circles) until it is found. This way, it is possible to set a value in an outer configuration context, and use it within.

$value = $c->grab_cfg(key => {..}, options => {..}, context=>{..})

By default: options : $self->default_options_for_banal_get_data() context : $self->cfg_context();

reload()

Reload the configuratoin file from disk.

load()

Reload the configuratoin file from disk (when the first such call needs to be distinguished, as opposed to reload().)
