I was wondering if there is any way to hook into Revise’s compilation cycle. I’m aware of `entr` which is great when watching files - and basically what I’m looking for is similar behavior but for code changes that are not saved to a file. The use case here is code being evaled in the REPL or VSCode and invoking a function when recompilation is complete (in my case reloading a web page).

Does `Revise.add_callback` do what you need?

Fantastic, thank you!

Sorry, I should’ve checked the API docs, I’ve only read the tutorials and haven’t found this.
