NAME
Dancer2::Plugin::Locale - Localize your Dancer2 application
VERSION
This document describes Dancer2::Plugin::Locale version 0.05
SYNOPSIS
In your app:
use Dancer2;
use Dancer2::Plugin::Locale;
…
locale->maketext('You are [numf,_1] of [numf,_2].', 42, 99);
…and from template
<div id="req_msg">[% locale.maketext('You have [quant,_1,request,requests].', req_count) %]</div>DESCRIPTION
Adds a locale keyword for your code and templates.
INTERFACE
locale
A lazy façade to get a locale handle suitable to the request. The locale object is a CLDR aware maketext format object.
It will be based on the session’s locale value if possible, then a configured default if possible, then 'en'.
The object, in more detail
The object is Locale::Maketext::Utils based.
Locale::Maketext::Utils extends Locale::Maketext a number of ways including:
It shifts toward CLDR based functionality which means you no longer have to create locale specific variants of code in each locale’s class.
Because of that and other utils it has, creating and dealing with the locale subclasses classes is much easier.
The object is a multiton (AKA an argument based singleton): "Argument based singleton" in Locale::Maketext::Utils
Adds a number of helpful methods: "METHODS" in Locale::Maketext::Utils
More sane fallback and lookup failure hooks: "Automatically _AUTO'd Failure Handling with hooks" in Locale::Maketext::Utils
Adds a very handy set of bracket notation methods (CLDR when possible) "Bracket Notation"
Available Locales
The locales available are determined by the lexicon files found in the appdir’s locale/ directory.
The name of each file must be a normalized version (See Locales::normalize_tag() in Locales) of an acceptable ISO tag. and end in with the extension .json.
Tip: To make them available to your UI you could simply symlink …/locale/ to …/public/locale.
Lexicon
A lexicon is a simple key/value hash where the key is the phrase and the value is the translation.
For example,in pseudo code:
# source phrase => target phrase
'Hello World' => 'Bonjour Monde'Each locale will have a lexicon hash in a file as desrcibed in "Available Locales".
The hash must be written in JSON format and be utf8 encoded.
Don’t be afraid of non-ASCII characters, just put them in the file as the character and it will work fine (if it doesn’t then it can help you track down bugs faster, win win!).
"I ♥︎ Dancer2!" : "私は♥︎ダンサー2"Bracket Notation
Bracket notation is described a bit more at "BRACKET NOTATION" in Locale::Maketext but is essentially a format to allow you to notate–within left and right square brackets, hence the name–dynamic portions of a phrase.
For example, include a non-translatable ever-changing name:
locale->maketext('Your email address, [_1], has been unsubscribed.', $email)or a number formatted according to the object’s locale’s CLDR data:
locale->maketext('You are user [numf,_1] of [numf,_2].', $place, $count)The bracket notation improvements over the core Locale::Maketext can be categoraized as follows:

Throws no errors of its own.
The only warning is during startup if you have a mis-named file in your locale/ directory:
<Skipping un-normalized locale named lexicon (%s.json) …>
