What's that, you say? You've become tired of regular old boring paper checklists? Well, my friend, today is your lucky day! You, yes, you, can become the proud owner of a brand-spanking-new automatic interactive pre-commit hook checklist! You're gonna love this! Your life will be so much easier! Just wait until your friends see you.
Did you know that nearly 1 out of 5 coders are too embarrassed to ask this question? Don't worry, it's perfectly normal. In the next 60 seconds we'll tell you all you need to know to pre-commit with confidence.
A Git hook is a feature of Git that triggers custom scripts at useful moments. They can be used for all kinds of reasons to help you automate your work, and best of all, you already have them! In every repository that you initialize with
git init, you'll have a set of example scripts living in
.git/hooks. They all end with
.sample and activating them is as easy as renaming the file to remove the
Git hooks are not copied when a repository is cloned, so you can make them as personal as you like.
The useful moment in particular that we'll talk about today is the pre-commit. This hook is run after you do
git commit, and before you write a commit message. Exiting this hook with a non-zero status will abort the commit, which makes it extremely useful for last-minute quality checks. Or, a bit of fun. Why not both!
I only want the best for my family and my commits, and that's why I choose an interactive pre-commit checklist. Not only is it fun to use, it helps to keep my projects safe from unexpected off-spec mistakes!
It's so easy! I just write a bash script that can read user input, and plop it into
.git/hooks as a file named
pre-commit. Then I do
chmod +x .git/hooks/pre-commit to make it executable, and I'm done!
Oh look, here comes an example bash script now!
#!/bin/sh echo "Would you like to play a game?" # Read user input, assign stdin to keyboard exec < /dev/tty while read -p "Have you double checked that only relevant files were added? (Y/n) " yn; do case $yn in [Yy] ) break;; [Nn] ) echo "Please ensure the right files were added!"; exit 1;; * ) echo "Please answer y (yes) or n (no):" && continue; esac done while read -p "Has the documentation been updated? (Y/n) " yn; do case $yn in [Yy] ) break;; [Nn] ) echo "Please add or update the docs!"; exit 1;; * ) echo "Please answer y (yes) or n (no):" && continue; esac done while read -p "Do you know which issue or PR numbers to reference? (Y/n) " yn; do case $yn in [Yy] ) break;; [Nn] ) echo "Better go check those tracking numbers!"; exit 1;; * ) echo "Please answer y (yes) or n (no):" && continue; esac done exec <&-
