The accept-charset header represents a list of character sets that the client can accept.

Nested Classes and Modules

class Charset

A parsed character set entry with an optional quality factor.

Definitions

CHARSET = /\A(?<name>#{TOKEN})(;q=(?<q>#{QVALUE}))?\z/

https://tools.ietf.org/html/rfc7231#section-5.3.3

def charsets

Parse the accept-charset header value into a list of character sets.

Signature
returns　Array(Charset)

the list of character sets and their associated quality factors.

Implementation

 
def charsets
	self.map do |value|
		if match = value.match(CHARSET)
			Charset.new(match[:name], match[:q])
		else
			raise ParseError.new("Could not parse character set: #{value.inspect}")
		end
	end
end

def preferred_charsets

Parse the accept-charset header and order character sets by preference.

Character sets with equal quality factors retain their original relative order.

Signature
returns　Array(Charset)

the preferred character sets.

Implementation

 
def preferred_charsets
	sort_by_quality_factor(charsets)
end
