    lang-detector

    NPM

    A fast and small library for detecting the programming language of a code snippet. Can be used for strings of code spanning multiple thousand lines.

    This library should only be used if you don't have anything else to go by to determine the language of the code, like a file extension.

    Detectable languages

    • JavaScript
    • C
    • C++
    • Python
    • Java
    • HTML
    • CSS
    • Ruby
    • Go
    • PHP

    Install

    npm install lang-detector --save

    Usage

    /**
     * function detectLang(snippet, options) { ... }
     *
     * @snippet {String} The code snippet.
     * @options {Object} (Optional) {
     *   heuristic: {Boolean} Enable heuristic optimisation for better performance. `true` by default.

    var detectLang = require('lang-detector');
     
    detectLang('List<String> things = new ArrayList<>();')
        // =>    'Java'
    detectLang('console.log("Hello world");')
        // =>    'JavaScript'
    detectLang('Hello world.', { statistics: true })
        /* =>   {
