Great question! I’m not currently sure :) I’ve been fairly deliberate about building CodeTour in a language agnostic way, in order to ensure it could be applied to any file type within a codebase. This is partly why I haven’t based the tour definition experience on code comments: https://github.com/vsls-contrib/codetour/issues/38.
That said, I’m trying to keep an open-mind when it comes to increasing tour resiliency, since it may require language/platform-specific solutions. I’m not sure. If you had any thoughts, I’d love to hear them!
Another potential solution is to have a CI task, that could check to see how far the code has deviated from the original commit that the tour was recorded on, and notify you when the deviation crosses some threshold. Maybe that’s a terrible idea, but something like that would have the benefit of being language-agnostic.
