lingo

Very basic Golang library for i18n. There are others that do the job, but this is my take on the problem.

Features:

1. Storing messages in JSON files.
2. Support for nested declarations.
3. Detecting language based on Request headers.
4. Very simple to use.

Usage:

1. Import Lingo into your project

     import "github.com/kortem/lingo"

2. Create a dir to store translations, and write them in JSON files named [locale].json. For example:

     en_US.json
     sr_RS.json
     de.json
     ...
   

   You can write nested JSON too.

     {
       "main.title" : "CutleryPlus",
       "main.subtitle" : "Knives that put cut in cutlery.",
       "menu" : {
         "home" : "Home",
         "products": {
           "self": "Products",
           "forks" : "Forks",
           "knives" : "Knives",
           "spoons" : "Spoons"
         },
       }
     }

3. Initialize a Lingo like this:

     l := lingo.New("default_locale", "path/to/translations/dir")

4. Get bundle for specific locale via either string:

     t1 := l.TranslationsForLocale("en_US")
     t2 := l.TranslationsForLocale("de_DE")

   This way Lingo will return the bundle for specific locale, or default if given is not found. Alternatively (or primarily), you can get it with *http.Request:

     t := l.TranslationsForRequest(req)

   This way Lingo finds best suited locale via Accept-Language header, or if there is no match, returns default. Accept-Language header is set by the browser, so basically it will serve the language the user has set to his browser.

5. Once you get T instance just fire away!

     r1 := t1.Value("main.subtitle")
     // "Knives that put cut in cutlery."
     r1 := t2.Value("main.subtitle")
     // "Messer, die legte in Besteck geschnitten."
     r3 := t1.Value("menu.products.self")
     // "Products"
     r5 := t1.Value("error.404", req.URL.Path)
     // "Page index.html not found!"

I regard this little library as feature-complete, but if you have an idea on how to improve it, feel free to create issues. Also, pull requests are welcome. Enjoy!
