Fluent Resource Manager

fluent-resmgr is an implementation of resource manager for Project Fluent.

Resource Manager provides a standalone solution for managing localization resources which can be used by fluent-fallback or other higher level bindings.

crates.io Build and test Coverage Status

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.



use fluent_resmgr::resource_manager::ResourceManager;

fn main() {
    let mgr = ResourceManager::new("./examples/resources/{locale}/{res_id}".into());

    let bundle = mgr.get_bundle(locales, resources);

    let value = bundle.format_value("hello-world", None);

    assert_eq!(&value, "Hello, world!");


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.

Local Development

cargo build
cargo test
cargo run --example simple

When submitting a PR please use cargo fmt (nightly).

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.
