Diff algorithm in Xojo

Does anybody have a diff algorithm for comparing two text files? I’ve found some with Google that I could port, but why reinvent the wheel if I don’t have to?

What about running it through diff on the command line and parsing those results?

I think Norman has one.

Viable, but I’d need to find something that I could distribute with my app.

Good call. https://github.com/npalardy/DiffEngine
