Flourite - Language detector

A fork of ts95/lang-detector, rewritten in Typescript with more language support.

Detects a programming language from a given string.

• Built-in support for CommonJS and ESM format
• Built-in Typescript typings
• No external dependencies
• 200 test cases and growing!

Detectable languages

Install

$ npm install flourite

or via a CDN (unpkg or jsdelivr)

Usage

import flourite from 'flourite';

const code = flourite('cout << "Hello world" << endl;');

// {
//   language: 'C++',
//   statistics: {
//     C: 0,
//     Clojure: 0,
//     'C++': 5,
//     CSS: 0,
//     'C#': 0,
//     Dockerfile: 0,
//     Elixir: 0,
//     Go: 0,
//     HTML: 0,
//     Java: 0,
//     Javascript: 0,
//     Julia: 2,
//     Kotlin: 0,
//     Lua: 2,
//     Markdown: 0,
//     Pascal: 0,
//     PHP: 0,
//     Python: 0,
//     Ruby: 0,
//     Rust: 0,
//     SQL: 0,
//     Unknown: 1,
//     YAML: 0,
//   },
//   linesOfCode: 1
// }

Or if you want to integrate it with Shiki, you could pass:

flourite('Console.WriteLine("Hello world!");', { shiki: true }).language;
// => csharp
flourite('fn partition(v: &mut [T], f: &F) -> usize ', { shiki: true }).language;
// => rust

If you want to handle Unknown value, you could pass:

const code = flourite("SELECT 'Hello world!' text FROM dual;", { noUnknown: true });

With Typescript

import flourite from 'flourite';
import type { Options } from 'flourite';

const flouriteOptions: Options = {
  heuristic: true,
};

const code = flourite('print!({:?}, &v);', flouriteOptions);

I'm here for Hacktoberfest, what can I do?

If you're new to open source, we really recommend reading a few articles about contributing to open source projects:

• Open Source Guide's How to Contribute to Open Source
• Hacktoberfest Contributor's Guide: How To Find and Contribute to Open-Source Projects
• Tips for high-quality Pull Request

Then you can start by reading our contribution part and guidelines.

Two things that you can do for sure: Create a new language support and improve the regular expression performance on current supported languages.

Have fun!

Contributing

• Use the Node.js version as defined on the .nvmrc file.
• Run npm run test:tdd to initiate a test driven development environment.
• Run npm run lint and npm run format before commit a change.
