- A friend got an error message when trying to use `brew extract` and it wasn't immediately obvious to me why. The usage banner only mentioned the "formula" argument, which they'd provided. This improves the error message when there aren't enough arguments so that others have a chance of figuring out how to use this command without having to look at the code for `extract_args`. Before: ``` ➜ brew extract --version='1.4' libftdi Usage: brew extract [--version=] [--force] formula ... [...] Error: Invalid usage: this command requires a formula argument ``` After: ``` ➜ brew extract --version='1.4' libftdi Usage: brew extract [options] formula tap [...] Error: Invalid usage: This command requires at least 2 named arguments. ``` - I don't like the "at least 2" phrasing here but that's a dive into the arg parsing code that I don't have time for right now. An alternative was `named_args [:formula, :destination_tap]`, but that gave the error message "requires formula or destination_tap" which wasn't great either. I also tried `min: 2, max: 2` and that was the same "at least 2" message.
