A flexible internationalization library working with JSON files in Haxe.

• Does not assume the task of handling the origin/source of the translations (e.g. opening files).
• Has nothing about date localization.
• Has been made with coded strings (welcome/hello) as translation key in mind, not sentences in a source language (Hello!).
• No additional dependency.

Install with Haxelib:

haxelib install jsoni18n

Then, Haxe command line arguments or in a HXML file:

-lib jsoni18n

It's JSON, objects and strings:

{
    "welcome": {
        "hello": "Hoy!",
        "subtitle": "Welcome, :name!",
        "content": {
            "main": "Main content should be longer but you get the idea.",
            "side": "Some useful side notes to shine in society."
        }
    },
    "news": {
        "list": {
            "0": "Nothing to display.",
            "1": "Only one new item.",
            "_": ":_ new items."
        }
    },
    "person": {
        "f": "Woman", "m": "Man", "$": "Person"
    },
    "secret": {
        "intro": "It's a secret page! Do you have authorization?"
    }
}

Import:

import jsoni18n.I18n;

Initialization:

var i18n : I18n = new I18n();

Load data:

var jsonFileContent : String = myLangFileLoader();
i18n.loadFromString(jsonFileContent);

Now, to translate something:

var hello : String = i18n.tr("welcome/hello"); // Hoy!

You can add a prefix to keys from all data fetched by loadFromString() like this:

i18n.loadFromString(data, "ui/");
i18n.tr("ui/welcome/hello"); // Hoy!

You can pass variables to strings returned by tr() like this:

i18n.tr("welcome/subtitle", [ "name" => "Nekith" ]); // Welcome, Nekith!

It also handles pluralization for your convenience.

i18n.tr("news/list", [ "_" => 0 ]); // Nothing to display.
i18n.tr("news/list", [ "_" => 12 ]); // 12 new items.

It also handles concordance for your convenience.

i18n.tr("person", [ "$" => "f" ]); // Woman
i18n.tr("person", [ "$" => "o" ]); // Person

i18n.depthDelimiter    =  ".";  // default: "/"
i18n.varPrefix         =  "@";  // default: ":"
i18n.pluralizationVar  =  "*";  // default: "_"
i18n.concordVar        =  "^";  // default: "$"
