if Code.ensure_loaded?(Plug) do
defmodule Cldr.Plug.AcceptLanguage do
@moduledoc """
Parses the accept-language header if one is available and sets
`conn.private[:cldr_locale]` accordingly. The locale can
be later retrieved by `Cldr.Plug.AcceptLanguage.get_cldr_locale/1`
## Options
* `:cldr_backend` is any backend module. The default
is `Cldr.default_backend/0`. If no `:cldr_backend`
option is provided and no default backend is configured
then an exception will be raised.
* `:no_match_log_level` determines the logging level for
the case when no matching locale is configured to meet the users
request. The default is `:warn`. If set to `nil` then no logging
is performed.
## Example
# Using a specific backend to validate
# and match locales
plug Cldr.Plug.AcceptLanguage,
cldr_backend: MyApp.Cldr
# Using the default backend to validate
# and match locales
plug Cldr.Plug.AcceptLanguage
