SYNOPSIS

Good example of the input and output.

# If language quality is the same then order by match method's input list
my $accept_language = HTTP::AcceptLanguage->new('en;q=0.5, ja;q=0.1');
$accept_language->match(qw/ th da ja /); # -> ja
$accept_language->match(qw/ en ja /);    # -> en

my $accept_language = HTTP::AcceptLanguage->new('en, da');
$accept_language->match(qw/ da en /); # -> en
$accept_language->match(qw/ en da /); # -> en

You can obtain the order of preference of the available languages list of client

my $accept_language = HTTP::AcceptLanguage->new('en, ja;q=0.3, da;q=1, *;q=0.29, ch-tw');
$accept_language->languages; # -> en, da, ch-tw, ja, *

You can use the 0.01 version spec. (next version is deplicated)

local $HTTP::AcceptLanguage::MATCH_PRIORITY_0_01_STYLE = 1;


my $accept_language = HTTP::AcceptLanguage->new('en, da');
