Carmen

What in the world is en-US-sandiego?

Carmen.js is, in a nutshell, a RFC-4646 & RFC-5646 parser. In other words, Carmen will parse strings like "en-US-sandiego" and tell you that it refers to the english language, in the United States, specifically, the variant spoken in San Diego.

Installation

npm install @kmdavis/carmen

Usage

import carmen from "@kmdavis/carmen";
carmen("en-US");

will return

{
  text: "en-US",
  language: "en",
  region: "US",
}

and

carmen("sl-Latn-IT-nedis");

will return

{
  text: "sl-Latn-IT-nedis",
  language: "sl",
  script: "Latn'"
  region: "IT",
  variants: ["nedis"],
}

The full list of fields that Carmen can return is:

{
  text:        String,
  language:    String,
  extlangs:    [String],
  script:      String,
  region:      String,
  variants:   [String],
  extensions:  Object,
  private:    [String],
  grandfather: String
}

Please note that the "text" field is Not the original string that is passed in. This string is reconstructed from the parsed values; as such, any minor formatting errors (such as the common Internet Exploder bug where en-US becomes en_US) will be normalized.
