Installation

[dependencies]
armature-i18n = "0.1"

Quick Start

use armature_i18n::{I18n, Locale};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let i18n = I18n::new()
        .add_bundle("en", include_str!("locales/en.ftl"))
        .add_bundle("es", include_str!("locales/es.ftl"));

    // Simple translation
    let msg = i18n.t("en", "hello")?;

    // With arguments
    let msg = i18n.t_args("en", "greeting", &[("name", "World")])?;

    // Pluralization
    let msg = i18n.t_plural("en", "items", 5)?;

    Ok(())
}

Fluent Files

# locales/en.ftl
hello = Hello!
greeting = Hello, { $name }!
items = { $count ->
    [one] { $count } item
   *[other] { $count } items
}

Locale Detection

use armature_i18n::Locale;

// Parse Accept-Language header
let locales = Locale::from_accept_language("en-US,en;q=0.9,es;q=0.8");

// Negotiate best locale
let best = i18n.negotiate(&locales, &["en", "es", "fr"]);
