> I am curious if there's been any work on _semantic_ diff tools as well (for when eg the syntax changes but the meaning is the same) We are working on https://semanticdiff.com/ https://semanticdiff.com/ which detects basic semantic changes like converting a literal from decimal to hex or reordering keys within JSON objects. It is not a command line utility but a VS Code extension and GitHub App. You can check out https://semanticdiff.com/blog/semanticdiff-vs-difftastic/ https://semanticdiff.com/blog/semanticdiff-vs-difftastic/ if you want to learn more about how it works and how it differs from difftastic.
