.config_find(name, default_key = '') ⇒ String

Return the value stored at the option named key, or the value given by the string default if the option in question is not set.

Params:

name

Key name.

default_key

Default key when config option not set.

Returns:

  • (String)

}

.config_find_file(name, default_key = '') ⇒ String

Locate the given key using find() and return the path to the file/directory. This uses a special algorithms which moves upwards in the configuration space and prepends the values of the options to the result. These methods are generally used for the options stored in the ‘Dir’ section of the configuration.

Params:

name

Key name.

default_key

Default key when config option not set.

Debian::AptPkg::Configuration.config_find_file('Dir::Etc::main') # => "/etc/apt/apt.conf"

Returns:

  • (String)

.languages ⇒ Array

Return the list of languages code.

Params:

all
