litelocale

🇪🇸 轻量级 Rust 国际化库。

# Add to your Cargo.toml file dependencies:
litelocale = "0.1.0" 
# or: litelocale = { git = "https://github.com/stpettersens/litelocale.git" }

您可以使用 litelocale 为您的 Rust 程序提供简单的国际化。

以下是一个简单的程序，可以根据选定的区域显示从 1 到 5 的数字，英文或西班牙语。

extern crate litelocale;
use litelocale::*;

fn main() {
    // Declare a vector of numbers in English.
    let nums = vec!["one", "two", "three", "four", "five"];
    // Declare a new locale, Spanish (Español, es).
    let mut es = Locale::new();
    // Select es as the locale.
    let sel = "es";
    // Load Spanish (es) locale when English (en) is not selected.
    if sel != "en" {
        // Add each number to locale.
        // English-Spanish-Phonetic Spanish (phonetics are optional).
        es.add_message(LocaleMessage::new("one", "uno", "oono"));
        es.add_message(LocaleMessage::new("two", "dos", "dos"));
        es.add_message(LocaleMessage::new("three", "tres", "trez"));
        es.add_message(LocaleMessage::new("four", "cuatro", "katro"));
        es.add_message(LocaleMessage::new("five", "cinco", "finco"));

        /* It is recommended in more substantial programs that you instead
           deserialize LocaleMessages from an external structure.
           E.g. from JSON using serde_json:

           let mut locale = Locale::new();
           if sel != "en {
               let file = File::open("my_locale.json");
               for line in BufReader::new(file).lines() {
                   locale.add_message(
                   serde_json::from_str(&line.unwrap())
                   .unwrap()); 
                   // <- {"locstr":"one","message":"uno","phonetic":"oono"}
                   // , etc.
               }
           }
        */
    }
    // Print each number in Spanish as sel == "es".
    // localize returns the localization for each English word.
    for n in nums {
        println!("-> {}", localize(n, &es)); // -> uno, -> dos, -> tres, etc.
        // If sel == "en"; output is as-is in original vector:
        // -> one, -> two, -> three, etc.
    }
}
