lingo

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

Features:

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

Usage:

Import Lingo into your project
```
  import "github.com/kortem/lingo"
```

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"
      },
    }
  }

Initialize a Lingo like this:

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

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.

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!
