fluent-rs is a Rust implementation of Project Fluent, a localization framework designed to unleash the entire expressive power of natural language translations.

Project Fluent keeps simple things simple and makes complex things possible. The syntax used for describing translations is easy to read and understand. At the same time it allows, when necessary, to represent complex concepts from natural languages like gender, plurals, conjugations, and others.

[dependencies]
fluent = "0.1.2"

extern crate fluent;

use fluent::MessageContext;

fn main() {
    let mut ctx = MessageContext::new(&["en-US"]);
    ctx.add_messages("hello-world = Hello, world!");

    let value = ctx.get_message("hello-world").and_then(|message| {
        ctx.format(message, None)
    });

    assert_eq!(value, Some("Hello, world!".to_string()));
}

The implementation is in its early stages and supports only some of the Project Fluent's spec. Consult the list of milestones for more information about release planning and scope.

FTL is a localization file format used for describing translation resources. FTL stands for Fluent Translation List.

FTL is designed to be simple to read, but at the same time allows to represent complex concepts from natural languages like gender, plurals, conjugations, and others.

hello-user = Hello, { $username }!

Read the Fluent Syntax Guide in order to learn more about the syntax. If you're a tool author you may be interested in the formal EBNF grammar.
