zsh plugin to add prompt reminders for git user.email

Do you git commit under multiple email addresses depending on the situation? (For example different addresses for work and open source projects.) Tend to forget which one you have active at a given time, leading to having to amend commits to fix it? This is for you.

I personally use this to have an emoji in my prompt to remind me which email will be recorded when I git commit.

The shell function git_prompt_useremail will echo the email address your next commit will be attributed to (checking both the $GIT_AUTHOR_EMAIL environment variable and the local git-config cascade for user.email.)

More importantly, the git_prompt_useremail_symbol function will echo to you a handy user definable emoji/icon/unicode-glyph for quick recognizeability!

To define the symbols, add entries to your git configuration (~/.gitconfig or also see git-config for details of the many options there), with the format:

[emailprompt "bwayne73@hotmail.com"]
    prompt = 🥂
[emailprompt "bruce@wayne-enterprises.biz"]
    prompt = 👔
[emailprompt "batman@justice-league.usa.gov"]
    prompt = 🦇

I personally like to put this one in my $RPROMPT.

export RPROMPT='$(git_prompt_useremail_symbol) '

Note that extra space at the end makes emoji in the RPROMPT look better in the macOS terminal. The single quotation marks are important though, so that the execution happens every time $RPROMPT is evaluated rather than when you first set it.

Add antigen bundle mroth/git-prompt-useremail to your .zshrc with your other bundle commands.

Antigen will handle cloning the plugin for you automatically the next time you start zsh. You can also add the plugin to a running zsh with antigen bundle mroth/git-prompt-useremail for testing before adding it to your .zshrc.

1. cd ~/.oh-my-zsh/custom/plugins
2. git clone https://github.com/mroth/git-prompt-useremail
3. Add git-prompt-useremail to your plugin list - edit ~.zshrc and change plugins=(...) to plugins=(... git-prompt-useremail)

Add zgen load mroth/git-prompt-useremail to your .zshrc file in the same function you're doing your other zgen load calls in. Zgen will handle automatically cloning the plugin for you the next time you do a zgen save.

This script should work fine in bash as well, I just haven't tested it. PRs with modifications and installation instructions are very welcome!
