Has anyone come across this?
Pretty interesting read if you know some c/c++.
I look forward to seeing it completed and reading about the lexer.
I’ve attempted to make sense of the source before to no real eval due to the complexity. Though this book seems to be breaking down the complexity pretty well.
It is interesting to see how it all comes together behind the scenes so far with arrays and oop.
