defmodule Cldr.LanguageTag.Sigil do
@moduledoc """
Implements a `sigil_l/2` macro to
constructing `t:Cldr.LanguageTag` structs.
"""
@doc """
Handles sigil `~l` for language tags.
## Arguments
* `locale_name` is either a [BCP 47](https://unicode-org.github.io/cldr/ldml/tr35.html#Identifiers)
locale name as a string or
* `locale_name` | `backend` where backend is a backend module name
## Options
* `u` Will parse the locale but will not add
likely subtags and its not guaranteed that this
language tag is known to the backend module.
## Returns
* a `t:Cldr.LanguageTag` struct or
* raises an exception
## Examples
iex> import Cldr.LanguageTag.Sigil
iex> ~l(en-US-u-ca-gregory)
#Cldr.LanguageTag<en-US-u-ca-gregory [validated]>
iex> import Cldr.LanguageTag.Sigil
iex> ~l(en-US-u-ca-gregory|MyApp.Cldr)
#Cldr.LanguageTag<en-US-u-ca-gregory [validated]>
