Additional completion definitions for Zsh
brew install zsh-completions
To activate these completions, add the following to your .zshrc:
fpath=(/usr/local/share/zsh-completions $fpath)
plugins=(… zsh-completions)
autoload -U compinit && compinit
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'
