This script enriches the github pull request page with so called 'incremental diffs'. This means that you will get a diff for changes pushed to that pull request, showing the difference before and after the push.

This is particular useful for situations where the reviewee was asked to do some changes in their existing commits (not additional commits). The reviewer can then use this to see those changes directly, not having to go through all the commits again, making sure the requested changes were addressed.

All this works by using github webhook, an external server and this script.

User Setup

After navigating to any pull request page, the script will ask you to setup a personalized access token for github so it can access the github API.

The hash data url is optional and not required for the normal user. If you do need it, your repository admin should have told you about it.

You can change your configuration settings later anytime by clicking on the Incremental Diffs Setup button at the bottom of the right sidebar. This also tells you whether the userscript is properly loaded.
