This is a Node.js library that helps derive `process.argv` array into a flexible, value-strict, TypeScript-friendly object.

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
exports.parseBoolean = parseBoolean;
const FalsyExpression = /^(false|0|n|no|off)$/i;
function parseBoolean(value, defaultValue = false) {
    if (value === undefined) {
        return defaultValue;
    }
    if (value === null || value === '') {
        return false;
    }
    if (typeof value === 'boolean') {
        return value;
    }
    if (typeof value === 'number' && isNaN(value)) {
        return false;
    }
    if (FalsyExpression.test(String(value).trim())) {
        return false;
    }
    return true;
