What is subarg?

The 'subarg' npm package allows you to parse command-line arguments with nested sub-arguments. This is particularly useful for complex command-line interfaces where arguments can have their own sub-arguments.

What are subarg's main functionalities?

Basic Parsing

This feature allows you to parse command-line arguments into a structured object. The `process.argv.slice(2)` part skips the first two default arguments (node and script path).

const subarg = require('subarg');
const argv = subarg(process.argv.slice(2));
console.log(argv);

Nested Arguments

This feature allows you to parse nested sub-arguments. For example, `--foo [--bar baz]` will be parsed into an object where `foo` is an array containing an object with `bar` set to `baz`.

const subarg = require('subarg');
const argv = subarg(process.argv.slice(2));
console.log(argv);
// Example: node script.js --foo [--bar baz]

Default Values

This feature allows you to set default values for arguments. If an argument is not provided, it will take the default value specified.

const subarg = require('subarg');
const argv = subarg(process.argv.slice(2), { default: { foo: 'default' } });
console.log(argv);
// Example: node script.js
