Description of issue

I wanted to be able to make a list that had all my casks and leaves with their homepages.

I did it. but it has to curl the brew info for every single one thus its quite slow. I don't know if this is the right place to ask for such a feature request but I'm all ears if anyone would like to help me implement this in a better way.

JSON output is your friend, and there's a whole page with explanations and examples.

For your specific use case, extracting the desired information for casks in TSV (tab-separated values) format is as simple as:

brew info --json=v2 $(brew ls --cask) | jq -r '.casks[] | [.token, .homepage] | @tsv'

and for leaves:

brew info --json=v2 $(brew leaves) | jq -r '.formulae[] | [.full_name, .homepage] | @tsv'

Ya know at my first go at writing a script that did this, I used:

brew info --json --eval-all| jq -r '.[].name' > all-formulae

but didn't think to research more in that direction 🤦‍♀️

I have put more hours into this than I'm willing to admit. Thank you for cluing me in so brutally quickly 😆

I just updated my script and its 16x faster 🙏
