i18nify

简体中文| English

Internationalization library for Rust based on code generation.

The original repository https://github.com/davidpdrsn/i18n_codegen was implemented by David Pedersen. However, it has some outdated dependencies and has not been maintained for as long as five years.

By leveraging code generation we are able to prevent common bugs like typos in i18n keys, missing interpolations, or various mistakes between locales.

It requires a directory (based on CARGO_MANIFEST_DIR) with one JSON file per locale. Here is an example with English and Danish translations:

// tests/doc_locales/en.json
{
    "hello_world": "Hello, World!",
    "greeting": "Hello {name}"
}

// tests/doc_locales/da.json
{
    "hello_world": "Hej, Verden!",
    "greeting": "Hej {name}"
}

And in Rust:

在 `Rust` 中：
```rust
use demo::Internationalize;

mod demo {
    use i18nify::I18N;
    #[derive(I18N)]
    #[i18n(folder = "tests/doc_locales")]
    pub struct DocLocale;

}

fn main() {
    // 基于 Locale 枚举类型获取国际化文本
    let hello = demo::Locale::En.hello();
    assert_eq!("Hello, World!",hello);
    println!("{}",hello);

    // 基于 `DocLocale` 实现的`Internationalize` trait 获取国际化文本
    let hello = demo::DocLocale.da().hello();
    println!("{}",hello);
}
