Creating a CPython Extension
Previously, as part of my exploration into how programming languages are implemented, I wrote a very simple AST evaluator that knew how to add and multiply floats together. Since constructing these ASTs by hand is quite painful I thought it would be fun to come up with a frontend to my “programming language” which could do it for me.
Now your typical frontend would be some kind of parser built into the compiler/interpreter. However, while I’m definitely interested in parsing I don’t quite feel like tackling that just yet. Instead I’m going to have Python be the frontend and embed my toy language into it via a CPython Extension
