Implementation discussion nyan-rs library

[simonsan]

This is the component overview of nyan from the master thesis of Jonas Jelten.

An example nyan file you can find here example.nyan

I would propose that we use logos/logos-derive to create our lexer.

Tokens are found in the masters thesis as well on p.40:

For the parsing into some rust structs we can use pest.rs and create a pest-file with parsing expression grammars (or PEG) for nyan as an input.

For the nyan type and value databases we could maybe use a component-graph-system like froggy, create a Rust API and build cdylibs.

Something like Legion and PumpkinDB sound promising as well, but are either pure ECS or lack other features we might want to have. For example PumpkinDB has ACID transactions, but has the last activity 3 years ago.

Probably also to use C2Rust partly and refactor to/rewrite idiomatic Rust?
