Idea to include `global.argv` / `minimist`? about zx

[antonmedv]

Done! Minimist in v2.

We could consider detecting numbers, and parsing those, but that already makes it tricky.

No need for that. If a script uses the API it already knows if an argument should be a number. Stuff like that should be handled by the script writer. A simple string/boolean case should be enough.

Maybe instead of going for popularity of a parsing package one could argue that the smallest one with the fastest loading time might be the best to choose. Just another way to look at the discussion.

Another argument parsing library to consider (I personally prefer it over minimist): https://github.com/vercel/arg

The problem with it what there are too many alternatives, and everybody wants a different one.

• yargs ~57M/week
• minimist ~41M/week
• arg ~7M/week
• meow ~15M/week
• countless others ~100M/week

arg is definitely the closest to the metal and inline with zx's vision.

I was thinking about limiting the integration to expose the arguments under global.argv, in the most basic form. Arguments would be exposed as strings when a value was provided (zx script.js --username smeijer), or booleans when not (zx script.js -xyz). We could consider detecting numbers, and parsing those, but that already makes it tricky.

Whenever the user needs more (like support for --help, or type coercion), they can install their library of choice.

For this project, I think the best option would be the simplest/smallest library.

Using zx for the first time and really enjoying it. This use case just came up as I wanted to add a little more configuration for other users who may use it. A simple way to get flagged arguments would be very nice. Maybe some inspiration can be taken from the Go flag package; simple, and if people still need more power than can install another one.

The difference I see between minimist and arg, is that minimist doesn't require any options/setup to be useful. While arg needs initialization.

As arg requires setup, one might as well just add the import statement as well.
