Everything About Felys

Felys is a dynamically strongly typed scripting language with a syntax similar to Rust. It provides minimal features to support data grouping with dynamic length, i.e., tuples and lists. The entire project is intended to be a toy language for demonstration purposes only. I have never considered turning this into a real product; instead, it serves as a tribute to Elysia from Honkai Impact 3rd.

Feel to try Felys using the online playground.

Topics

In short, there are three main topics that worth sharing:

  • Design principle that covers all the considerations involved in designing Felys.
  • Implementation of a PEG/Packrat parser along with a DFA-driven lexer.
  • Neural network framework with automatic differentiation and dynamic computation graph.

Some of these are a bit academic, but I believe this book should be accessible to most EE/CS undergraduates beyond their first year.

Most of these are not done yet. Writing takes time.
