for i in `brew ls`; do brew info $i | grep -e 'Built.*with:' >/dev/null && brew info $i; done
Out of 144 formulas installed, I've only got one with an option (mpv --with-bundle). I hope the Homebrew folks will use that option as default, but I suspect they won't, and will recommend the cask instead. Which isn't really what I want, but ok.
No need to feel dependent on Homebrew maintainers’ whims. You’re free to copy the formula, customize it the way you want, push it to your repo on GitHub, and `brew tap` it.
No need to use the Cask version if you don’t want to. If you feel stuck with the tap thing, you’re welcome to get in touch on discourse.brew.sh and we’re glad to help!
