List formulas that are manually installed

[mattcen]

Is there a way to list which formulas have been manually installed, as opposed to installed automatically as dependencies? I assume, given the presence of brew autoremove, that Homebrew keeps a record somewhere of this which packages were only installed as dependencies, but I'm not sure how to access this information.

Try brew bundle dump. That creates a Brewfile in the current directory that should include all the formulae you've installed on request. You can also do brew leaves to see all the installed formulae that are not dependencies of another currently installed formula.

Ah, sweet; that looks like it'll do what I want! Thanks so much for the quick and clear response! 😄

As an update, I think you can now do

brew list --installed-on-request
