linguist-js/dist/analyser/classifiers/byFilename.js

Analyse the programming languages used in a folder or from raw content, using the same rules that GitHub Linguist does.

import Path from 'node:path';
export default function byFilename(file, langData) {
    const filename = Path.basename(file.path).toLowerCase();
    // Check if filename is a match
    return Object.entries(langData)
        .flatMap(([lang, data]) => {
        const matches = data.filenames?.some((name) => name.toLowerCase() === filename);
        return matches ? [lang] : [];
    });
}
