adding git branch info to macos zsh prompt, and using pico

I'm trying to get a more fluent with command-line git, and it's pretty easy to get zsh to show you the current git branch as your prompt. Here's my new ~/.zlogin:

alias ls="ls -F"

autoload -Uz vcs_info

precmd() { vcs_info }

# Format the vcs_info_msg_0_ variable

zstyle ':vcs_info:git:*' formats ' 🛰 %b'

# Set up the prompt (with git branch name)

setopt PROMPT_SUBST

PROMPT='${PWD/#$HOME/~}${vcs_info_msg_0_} 🚀'

I like using emoji as concise and obvious at a glance prompt delimiters.

Also I have to be sure to set a default editor I am comfortable with:
git config --global core.editor "nano"
Interesting that emacs doesn't ship with MacOS, but I'm not so enamored of it that I'm going to seek it out. Never got my mind around the modality of vim. nano/pico feel kind of clunky and almost DOS-ish, but for the small number of tasks where it's not worth firing up Visual Studio Code, it's fine.
