Topic: Lean's components

Johan Commelin (Nov 01 2022 at 15:31):

I think I saw a presentation by Johannes Hölzl several years ago, where he had a diagram that showed how all Lean's components interacted: parser, elaborator (including tactic framework, type class resolution), kernel, virtual machine, etc...

Does someone know hot to get

  • that diagram, or
  • an equivalent diagram, or
  • a textual representation of something like that?

In early versions of the Lean 4 presentations given by @Sebastian Ullrich there were such diagrams for Lean 3 and Lean 4. For example: http://leanprover.github.io/talks/vu2019.pdf

Thanks! That's exactly the kind of diagram I'm looking for!

For the backend, there's also http://leanprover.github.io/talks/WITS2022.pdf#page=6
