Yikes! A safer git push

yikes

#!/usr/bin/env bash
#
# When using "git push", I frequently find myself overlooking git's
# dreaded 'Updates were rejected because the remote contains work that
# you do not have locally' error message.
#
# After I push, I don't typically wait around for the command to
# complete. So while I _think_ that my changes have been pushed to
# remote branch, in fact the push wasn't successful. Because the
# branch has changed in the meantime, I need to `git pull --merge` to
# integrate before git allows me to push.
#
# In fact this happens so often that my colleagues are getting
# annoyed. Is there a way to make this more obvious? Make a sound?
# Show something really obvious on the screen, in case the speaker is
# muted?
#
# I'm glad you asked. Let me introduce you to yikes!
#
# Installation:
#
# - Calls this script `yikes`, make it executable and put in on your path
# - add this section to ~/.gitconfig
#
#     ```
# [alias]
#         yikespush  = "!git push \"$@\" || yikes"
#     ```
#
# - add this section to ~/.zshrc
#
#     ```
# function do_git {
#   cmd="$1"
#   if [[ "$cmd" == "push" ]]; then
#       cmd="yikespush"
#   fi
#   command git "$cmd" "${@:2}"
# }
# alias git='do_git'
#     ```
#
# This works on macOS and zsh. If you use fish on Linux, you're out of
# luck. On the upside, you're probably smart enough to translate these
# instructions to your preferred environment.
