toy_rustpython

This is a learning project where the point is to learn the Rust programming language by making a toy Python compiler

Goals

• Be a small enough project that I'll actually finish it.
• Learn Rust
• Learn How Python ByteCode works (maybe?).
• Learn how to implement a REPL.
• Be expandable if I want to continue working on this.
• Learn how to use Docker for local testing and how CircleCI or Github Actions can also use the same Docker Images.
• Build a test suite that can be re-used if I want to use this to learn other languages.

Operators

• +
• -
• *
