Have you tried claude?

node script.js --name=John --age 30 -v

Parsed options: { name: 'John', age: 30, verbose: true, help: false }

Positional arguments: []

node script.js --name=Alex --age 40 -v

Parsed options: { name: 'Alex', age: 40, verbose: true, help: false }

Positional arguments: []

I keep seeing that `args = process.argv.slice(2)` line to skip past `node script.js`

I ended up settling for it as well (I couldn't find anything better, nor make it break) but I'd be really surprised if it was the way to go

Like `node --enable-tracing script.js --name=John --age 30 --verbose`

This works because node seems to hide --enable-tracing to the underlying script

But would it work with Bun & Deno...? Is that standard...?

This one seems way better

It didn't account for the presence of a '--' to end the parsing of named arguments but that's it

That’s just something getopt does and some programs adopted. If you asked me to write a parser, I wouldn’t necessarily include that either if you didn’t ask for it.

If you don't include it you can't have positional arguments that look like options

Some positional arguments can be filenames, filenames can be --help and --verbose or --name=Frank

You have to have `--` or something similar to have a correct program
