How to use the nanomatch.match function in nanomatch

impl: (interpreter: Interpreter, pathArg: BrsString, patternIn: BrsString) => {
        let volume = getVolumeByPath(interpreter, pathArg.value);
        if (volume == null) {
            // TODO: replace with RoList when that's implemented
            return new RoArray([]);
        }

        let localPath = path.join(interpreter.options.root, getPath(pathArg.value));
        try {
            let knownFiles = fs.readdirSync(localPath, "utf8");
            let matchedFiles = nanomatch.match(knownFiles, patternIn.value, {
                nocase: true,
                nodupes: true,
                noglobstar: true,
                nonegate: true,
            });

            matchedFiles = (matchedFiles || []).map((match: string) => new BrsString(match));

            // TODO: replace with RoList when that's implemented
            return new RoArray(matchedFiles);
        } catch (err) {
            // TODO: replace with RoList when that's implemented
            return new RoArray([]);
        }
    },
});

module.exports = function(files, pattern) {
  return nanomatch.match(files, pattern);
};
