if_changed

Runs commands when files are changed on git pull: for example, when package.json is changed, npm install will be ran, installing the dependency updates.

See the source for a full list—it's pretty readable. Please send a pull request if your technology or desired command is missing!

Setup

You can either run this script manually every time you pull, or you can set it up on the post-merge git hook so that it runs automatically.

As of 1.0.0, you can install this over npm.

$ npm install -g if_changed

Then to run the script:

$ if_changed

And to install itself into the post-merge hook:

$ if_changed install

Manual install

To run every time, download if_changed.sh and run it.

To run automatically on the post-merge hook, move the if_changed.sh file to .git/hooks/post-merge in your repository (where post-merge is the name of the file, not a containing directory), and make it executable using chmod +x post-merge.

See this document to learn more about git hooks.
