🌍 Tarjama: Supercharge Your Rust App Internationalization πŸš€

Welcome to Tarjama, your go-to library for making your Rust applications accessible to speakers of different languages around the globe! πŸŽ‰

What's Tarjama? πŸ€”

Tarjama enables you to easily internationalize your Rust applications, supporting an extensive list of locales found in our Locale enum (src/locale.rs). With Tarjama, you can effortlessly switch between languages, catering to a global audience. 🌐

Getting Started πŸš€

Add Tarjama to your project using Cargo:

cargo add tarjama

or add it to your Cargo.toml:

[dependencies]
tarjama = "0.2.1"

Sample Usage πŸ› 

Basic Usage:

use tarjama::Translator;
use tarjama::context;

// load translations from a directory of toml files
let catalogue_bag = toml::load("path/to/translations").await?;
let mut translator = Translator::from_catalogue_bag(catalogue_bag);
// set the fallback locale to English
translator.set_fallback_locale("en");

// translate the message 'greeting' in the 'messages' domain with the context 'name' set to 'World' in English.
let message_en = translator.trans("en", "messages", "greeting", context!(name = "World"))?;
// translate the message 'greeting' in the 'messages' domain with the context 'name' set to 'δΈ–η•Œ' in Chinese,
// if the message is not found in Chinese, it will fallback to English, as it is set as the fallback locale.
let message_zh = translator.trans("zh", "messages", "greeting", context!(name = "δΈ–η•Œ"))?;

println!(message);

[!NOTE] Each message file in the translation directory is expected to be named using the {domain}.{locale}.toml format. For example, messages.en.toml for the English locale.

Manual Catalogue Creation:

Tarjama allows you to create your catalogue bag manually, as shown below:

use std::collections::HashMap;
use tarjama::Translator;
use tarjama::context;
use tarjama::catalogue::{Catalogue, CatalogueBag};
use tarjama::locale::{Locale, EnglishVariant};

let catalogue_bag = CatalogueBag::from_catalogues(vec![
    Catalogue::from_messages(Locale::English(EnglishVariant::Default), HashMap::from([
        ("messages".to_owned(), HashMap::from([
          ("greeting".to_owned(), "Hello, {name}!".to_owned()),
        ]))
    ])),
]);

let translator = Translator::from_catalogue_bag(catalogue_bag);

let message = translator.trans("en", "messages", "greeting", context!(name = "World"))?;

println!(message);

[!NOTE] If you plan on creating your catalogue bag manually, you could remove the toml feature from your Cargo.toml.

cargo add tarjama --no-default-features

This will reduce the size of your binary and remove the dependency on the toml crate.

Actix Web Integration 🌐

Tarjama provides an Actix Web middleware for easy integration with Actix Web applications. To use the middleware, add the actix-web feature to your Cargo.toml:

tarjama = { version = "0.2", features = ["actix-web"] }

Then, add the middleware to your Actix Web application:

use actix_web::{web, App, HttpServer};
use tarjama::actix::TarjamaMiddleware;
use tarjama::Translator;
use tarjama::context;
use tarjama::locale::{Locale, EnglishVariant};

async fn example(translator: Translator, locale: Locale) -> Result<HttpResponse> {
    let content = translator.trans(locale, "messages", "greeting", context!(name = "World"))
            .map_err(error::ErrorInternalServerError)?;

    Ok(HttpResponse::Ok()
        .content_type("text/plain")
        .body(content))
}

#[actix_web::main]
async fn main() -> std::io::Result<()> {
    let translator = Translator::with_catalogue_bag(
        load("/path/to/translations/").await.expect("couldn't load translations"),
    );

    HttpServer::new(move || {
        App::new()
            .wrap(TranslatorMiddleware::new(translator.clone(), Locale::English(EnglishVariant::Default)))
            .route("/", web::get().to(example))
    })
    .bind(("127.0.0.1", 8080))?
    .run()
    .await
}

Feature Flags 🚩

  • actix-web: For Actix Web middleware support, enabling this feature allows you to use the Tarjama middleware with Actix Web applications.
  • file: For basic file loader operations, this feature is useful for implementing custom loaders.
  • toml: For toml file support, enabling this feature allows you to load translations from toml files.
  • default: Includes toml.
