r18 is a crate for internationalized Rust projects.
Add r18 to your project's dependencies.
toml
[dependencies]
r18 = "0.1"
Create a JSON translation file whose name format is BCP 47 language tag in a directory and write it as follows:
json
// ./tr/zh-CN.json
{
"Hello, {}": "ä½ å¥½ï¼Œ{}"
}
Then add r18::init! to the global area of your code with the translation file directory path (is ./tr in this example) relative to your project root.
rust
r18::init!("tr");
After initialization, use auto_detect! to detect locale and load translation model (optional, you can use set_locale! to set locale manually), then use tr! to translate your text which has been translated.
```rust r18::init!("tr");
fn main() { r18::auto_detect!();
let name = "ho-229";
println!("{}", tr!("Hello, {}", name));
// reset locale to disable translation
r18::set_locale!("");
assert_eq!("Hello, ho-229", tr!("Hello, {}", name));
} ```
