I am always trying to connect programming to film & media in any way I can, so what better way than to take a picture of myself with my laptop’s webcam every time I commit some code.
Using a couple commands in terminal and a basic script, you can automate the process, so all you have to do is sit back, commit some code and be photogenic.
In this tutorial, I have compiled the best of other tutorials, gotchas, and related content I have come across on the web. At the end of this, you can even star you in your own git commit movie.
Just a heads up, this is geared towards OSX users… for everyone else, I will add more details when I come across Linux, Windows info 🙂
Step 1: Install imagesnap
brew install imagesnap
Step 2: Create post-commit hook
Add the following code from the gist below to a file called
post-commit in your repo’s
Step 3: Enable permissions
Lets give the file some permission (making it executable by everyone).
sudo chmod +x ~/.git/hooks/post-commit
Step 4: Start committing and smiling
On first run, the script will create a folder called
commit_images in your repo’s root. Then every time you commit code, a photo is added to the folder and to
.gitignore automatically so you don’t have to.
The only downfall to this solution is you have to add it to each of your git repos manually. So if you have a lot of repos it might be a pain, but then again thats what writing a script is for, right? So behold…the global solution (for new repos)!
1. Enable git templates. This will copy everything in the
.git-templates folder to any new git repositories when you
git config --global init.templatedir '~/.git-templates'
2. Create our hooks folder for the post-commit template.
mkdir -p ~/.git-templates/hooks
3. Add the
post-commit file in
~/.git-templates/hooks/. We can use the same script from above in step 2.
4. Make our post-commit executable. We are giving it executable permission to all users in this case.
sudo chmod +x ~/.git-templates/hooks/post-commit
5. Start committing and smiling. Every time we
git init, we now have the post-commit hook in all of our new repos.
Nice to Have
Here are some things I am looking into:
- Store pictures from all repos into one folder instead of in each individual repo. eg. in ~/.commit_images
- More to come…
Stitching It All Together (Movie Time)
More details in the link, but we can essentially use ffmpeg to create a short stop motion video of our commit images.
Final Product (The Movie)
I am planning on adding my own video when I amass some pictures, but in the mean time here is a short video sample.
