From bash to zsh…git and prompt configuration

After a really long journey I decided to retire my long-lasting and trustworthy companion, my 2012 MacBook Air. I spent quite some time to decide which new model to buy; in the end the presence of the touch bar made me avoid all other models and going for the latest 2020 MacBook Air.

I didn’t want to use one of my time capsule backup but have a new clean env to setup and so first thing first: git, bash-completion and customization of the prompt on zsh shell on macOs Catalina. I used brew to do it.

brew install git bash-completion

And then to make the completion available in zsh as suggested by homebrew website you must get the Homebrew-managed zsh site-functions on your FPATH before initialising zsh’s completion facility, so I added the following in the ~/.zshrc file:

if type brew &>/dev/null; then
  FPATH=$(brew --prefix)/share/zsh/site-functions:$FPATH
  autoload -Uz compinit && compinit
fi

Compinit was complaining about insecure directories, so I listed the insecure directory and added the correct permission for those.

zsh compinit: insecure directories, run compaudit for list.
Ignore insecure directories and continue [y] or abort compinit [n]? 

compaudit

This is because those folders are group writable, so I changes it:

compaudit | xargs chmod g-w

I do like do see in my prompt both the user and the machine name, the path I’m on and if it’s a git repository the branch name and adding some color. Next step will be adding some more icon to show the status of the git repository.

# Load version control information
autoload -Uz vcs_info
precmd() { vcs_info }

# Format the vcs_info_msg_0_ variable
zstyle ':vcs_info:git:*' formats '(%b)'

autoload -U colors && colors

# Set up the prompt (with git branch name)
setopt PROMPT_SUBST
PROMPT='%n@%m %F{green}${PWD/#$HOME/~}%f %F{yellow}${vcs_info_msg_0_}%f > '
zsh custom prompt
