About

I want to have a finite list I can rely on when listing available languages for web apps or to parse Accept-Language browser header to return the correct lang.

Features

• Parses from "iso 2" (fr), "iso 3" (fra) and "locale" (fr_FR, ru-RU) formats
• Can convert to "iso 2", "iso 3", or full text (like "French")
• Fault tolerent as it allows to parse with or without spaces and lower/uppercase

Installation

• Using V installer

Using V installer

Run this command at the root of your project:

v install khalyomede.lang

Examples
