  • marwood

    An embeddable Scheme R7 Compiler & Runtime written in Rust

    The lexer can be found here and parser here.

  • TablaM

    Exist some non-obvious things about interpreter implementation with Rust, so i share my opinions while building https://tablam.org:

  • inko

    You can use Inko as a reference, as its VM is written in Rust. I do recommend using this branch instead of the latest release, as there are a lot of upcoming changes to the language as a whole.

  • Oga

    In terms of parsing style I suggest sticking with a hand-written recursive-descent parser. Parser generators seem appealing at first, but I always ran into annoying limitations when using them (I wrote one in Ruby myself as well, and used this for this project). Parsing combinators are useful for small inputs, but I find them difficult to use for anything but simple cases.
