Diagram Comparison Feature Idea

[qtzar]

We are using Structurizr-site-generatr to hold our current state diagrams in the main/default branch and our engineering teams have the ability to create their own branches to show future state.

With this in mind I've been thinking of ways to show on diagram pages if an alternative version exists that might be different with a way to quickly do a comparison of the two diagrams in the different branches.

My initial thought is that you would have to do a site build twice, the first time to build the site for all branches as it works currently but also creating some sort of array of the md5 hashes in memory for each diagram built. Then on the second pass it would use that array to change the pages where the md5 hash don't match to rebuild the page with additional links to quickly switch to the same diagram on the different branch.

Open to other concepts or ideas on how this might be achieved...
