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 });

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

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

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

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!

• 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.
