HttpHeaders::AcceptLanguage

🔩 Utility to parse and sort the "Accept-Language" HTTP Header

Installation

Add this line to your application's Gemfile:

gem 'http_headers-accept_language'

And then execute:

$ bundle

Or install it yourself as:

$ gem install http_headers-accept_language

Usage

You can parse the "Accept-Language" header. As per the RFCs, you should really have one (delimited) value but the current implementation accepts an array of values.

require 'http_headers/accept_language'

parsed = HttpHeaders::AcceptLanguage.new('nl-NL, nl, en-US; q=0.4, en; q=0.1')
parsed.first.region
# => 'NL' 
parsed.last.q
# => 0.1
 
 
parsed = HttpHeaders::AcceptLanguage.new([
  'eo; q=0.1', 
  'es-ES; foo=bar, es-MX; q=0.9'
])
parsed.first[:foo]
# => bar
parsed.last.to_s
# => 'eo; q=0.1'
parsed[1].locale
# => 'es-MX' 

Each parsed entry has the following methods:

• locale: the parsed locale
• language: the language part of the locale
• region: the region part of the locale
• q: the quality parameter as float, or 1.0
• [](parameter): accessor for the parameter; throws if it does not exist
• to_s: encode back to an entry to be used in a Accept-Language header
