In OS X, is there any way to have Zsh (I'm using Oh-my-zsh) tab-complete formulas?
E.g.
$ brew install em<TAB> could expand to:
$ brew install emacs

Try installing the zsh-completions formula.
$ brew info zsh-completions zsh-completions: stable 0.10.0, HEAD https://github.com/zsh-users/zsh-completions Not installed From: https://github.com/Homebrew/homebrew/commits/master/Library/Formula/zsh-completions.rb ==> Caveats To activate these completions, add the following to your .zshrc: fpath=(/usr/local/share/zsh-completions $fpath) You may also need to force rebuild `zcompdump`: rm -f ~/.zcompdump; compinit Additionally, if you receive "zsh compinit: insecure directories" warnings when attempting to load these completions, you may need to run this: chmod go-w /usr/local/share It also looks like zsh may have some compatibility with bash completions. You could try that in conjunction with the bash-completions formula.

compinit -ishould solve the the "insecure directories" warnings rather than chmod.taddy hoops– taddy hoops2015-05-16 02:23:06 +00:00Commented May 16, 2015 at 2:23 - for the "insecure directories" error, use

Homebrew provides it's own completion. You just need to link the file $(brew --prefix)/Library/Contributions/brew_zsh_completion.zsh to _brew somewhere in your $fpath.(See comment at the start of https://github.com/Homebrew/homebrew/blob/master/Library/Contributions/brew_zsh_completion.zsh)
zsh-completions recently removed its _brew completion in favour of that file, see https://github.com/zsh-users/zsh-completions/issues/305.
Update 2016-04-19: At some point(1) Homebrew updated its handling of zsh completion again. Now if you install zsh via Homebrew it should "just work". The file is installed to /usr/local/share/zsh/site-functions/_brew.
