Fluent is a modern localization system designed to improve how software is translated. +//! +//! The Rust implementation provides the low level components for syntax operations, like parser +//! and AST, and the core localization struct - [`FluentBundle`]. +//! +//! [`FluentBundle`] is the low level container for storing and formatting localization messages +//! in a single locale. +//! +//! This crate provides also a number of structures needed for a localization API such as [`FluentResource`], +//! [`FluentMessage`], [`FluentArgs`], and [`FluentValue`]. +//! +//! Together, they allow implementations to build higher-level APIs that use [`FluentBundle`] +//! and add user friendly helpers, framework bindings, error fallbacking, +//! language negotiation between user requested languages and available resources, +//! and I/O for loading selected resources. +//! +//! # Example +//! +//! ``` +//! use fluent::{FluentBundle, FluentValue, FluentResource, FluentArgs}; +//! +//! // Used to provide a locale for the bundle. +//! use unic_langid::LanguageIdentifier; +//! +//! let ftl_string = String::from(" +//! hello-world = Hello, world! +//! intro = Welcome, { $name }. +//! "); +//! let res = FluentResource::try_new(ftl_string) +//! .expect("Failed to parse an FTL string."); +//! +//! let langid_en: LanguageIdentifier = "en-US".parse().expect("Parsing failed"); +//! 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("Message doesn't exist."); +//! let mut errors = vec![]; +//! let pattern = msg.value() +//! .expect("Message has no value."); +//! let value = bundle.format_pattern(&pattern, None, &mut errors); +//! +//! assert_eq!(&value, "Hello, world!"); +//! +//! let mut args = FluentArgs::new(); +//! args.set("name", FluentValue::from("John")); +//! +//! let msg = bundle.get_message("intro") +//! .expect("Message doesn't exist."); +//! let mut errors = vec![]; +//! let pattern = msg.value().expect("Message has no value."); +//! let value = bundle.format_pattern(&pattern, Some(&args), &mut errors); +//! +//! // The FSI/PDI isolation marks ensure that the direction of +//! // the text from the variable is not affected by the translation. +//! assert_eq!(value, "Welcome, \u{2068}John\u{2069}."); +//! ``` +//! +//! # Ergonomics & Higher Level APIs +//! +//! Reading the example, you may notice how verbose it feels. +//! Many core methods are fallible, others accumulate errors, and there +//! are intermediate structures used in operations. +//! +//! This is intentional as it serves as building blocks for variety of different +//! scenarios allowing implementations to handle errors, cache and +//! optimize results. +//! +//!
