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
• 150 test cases and growing!

Detectable languages

Languages
C	HTML	Lua	Rust
C++	Java	Pascal	SQL
C#	Javascript	PHP	YAML
CSS	Julia	Python
Go	Kotlin	Ruby

Install

$ npm install flourite

or via a CDN (unpkg or jsdelivr)

<script src="https://unpkg.com/[email protected]"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/index.iife.js"></script>

Usage

import flourite from 'flourite';

const code = flourite('console.log("Hello World");'); // => Javascript

You could supply options to make see numbers of points for a certain language:

import flourite from 'flourite';

const code = flourite('printf("Hello World")', { statistics: true });

// code.detected = 'C'
// code.statistics = {
//   C: 5,
//   'C++': 0,
//   'C#': 0,
//   CSS: 0,
//   Go: 0,
//   HTML: 0,
//   Java: 0,
//   Javascript: 0,
//   Julia: 0,
//   Kotlin: 0,
//   Lua: -20,
//   Pascal: 0,
//   PHP: 0,
//   Python: 0,
//   Ruby: 0,
//   Rust: 0,
//   SQL: 0,
//   Unknown: 1,
//   YAML: 0
// }

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

const code = flourite('Console.WriteLine("Hello world!");', { shiki: true }); // => csharp

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, StatisticOutput } from 'flourite';

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

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

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.
statistics	boolean	false	If true, will return the statistics of all the guessed language.
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

Development

• 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.
