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:

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!
