Suppose I have added a new tap to Brew using brew tap ....
I've tried looking into brew search, brew tap, and brew tap-info, but none of these subcommand present any suitable options.
How can I list all formulae available within that tap?

From this Stack Overflow article:
List of formulae in a tap can be found by running
brew tap-info $TAP --jsonTo turn this into a proper readable format we can run
brew tap-info $TAP --json | jq -r '.[]|(.cask_tokens[])'Example: To find all formulae in homebrew/cask-fonts we can do:
brew tap-info homebrew/cask-fonts --json | jq -r '.[]|(.cask_tokens[])'
Break down of the command:
brew tap-info homebrew/cask-fonts --jsonlists JSON info of the taps and some other stuff (output)jq -r '.[]removes the outside square bracket (output)|(.cask_tokens[])'gets the JSON value of the keycask_tokens
TL;DR: Running brew tap-info <tap-here> --json | jq -r '.[]|(.cask_tokens[])' will give you the formulae from that tap.
Note If this fails to list all try running brew tap-info <tap-here> --json | jq -r '.[]|(.formula_names[],.cask_tokens[])'

Why is
.formula_names[]necessary? May a tap contain both formulae and casks?– ShuzhengCommented Jun 4, 2020 at 12:34 -
@Shuzheng Hmm thats interesting. For me this change of removing
.formula_names[]made no difference to the output. From this paste we can see that there is a field with the key"formula_names". I am not sure if it is required to run with.formula_names[], but since the field is there in the JSON output I'm leaving it there for now.– RoxiunCommented Jun 4, 2020 at 12:52 -
@Shuzheng Yes, "Casks can be included in taps with formulae, or in a tap with just casks." See docs.brew.sh/How-to-Create-and-Maintain-a-Tap#casks. Moreover, a tap can also provide external commands, see docs.brew.sh/How-to-Create-and-Maintain-a-Tap#external-commands. Commented Jul 31 at 15:26
