Code repository for article "Writing githooks in Kotlin"
To be able to run Kotlin as a script you'll need to install KScript you can find the installation instructions here.
Doing a gradle build will install the githook pre-push script. You can check this line to see how this is achieved.
Next time you do git push the script will be executed. As part of the script gradle check will be executed. If the run is successful you'll be able to push, otherwise the push will be aborted.
For a more in-depth explanation of the code check the article: https://jivimberg.io/blog/2018/07/03/writing-githooks-in-kotlin/
