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

Languages
C	Dockerfile	Javascript	Pascal	SQL
C++	Elixir	Julia	PHP	YAML
C#	Go	Kotlin	Python	Typescript
Clojure	HTML	Lua	Ruby
CSS	Java	Markdown	Rust

Install

$ npm install flourite

or via a CDN (unpkg or jsdelivr)

<script src="https://unpkg.com/flourite@1.3.0"></script>
<script src="https://cdn.jsdelivr.net/npm/flourite@1.3.0/dist/index.iife.js"></script>

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<T,F>(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);

Available Options

Key	Type	Default	Description
heuristic	boolean	true	Checks for codes on the top of the given input. Only checks when the lines of code is above 500.
shiki	boolean	false	Straightforward compatibility with Shiki's language specification type
noUnknown	boolean	false	If true, will not output Unknown on detected and statistics result

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.
