Fluent
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.
Usage
use fluent_bundle::{FluentBundle, FluentResource};
use unic_langid::langid;
fn main() {
let ftl_string = "hello-world = Hello, world!".to_owned();
let res = FluentResource::try_new(ftl_string)
.expect("Could not parse an FTL string.");
let langid_en = langid!("en");
let mut bundle = FluentBundle::new(vec![langid_en]);
bundle.add_resource(&res)
.expect("Failed to add FTL resources to the bundle.");
let msg = bundle.get_message("hello-world")
.expect("Failed to retrieve a message.");
let val = msg.value.expect("Message has no value.");
let mut errors = vec![];
let value = bundle.format_pattern(val, None, &mut errors);
assert_eq!(&value, "Hello, world!");
}
Status
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.

Learn the FTL syntax
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.
