Looking for an offline tool with a nice UI for highlighting differences between 2 or more chunks of text. Bonus if I can hide some intermediate lines in the comparison. Could be a Julia package for strings, could be something else that just needs pasted text or text files (printed via `redirect_stdout` if not directly supported as an argument).

My first thought would be something like `vimdiff`?

I think VS Code also has a built-in diff viewer?

But it also may make a difference if you are doing e.g. `code_lowered` vs `code_llvm`? Presumably you want syntax highlighting?

Yes, though if the highlighting in printouts like `@code_warntype` isn’t feasibly replicable, I could live without it.
