parsley

Build Crates.io

what if scheme...but rust. still working on a backronym.

cargo install parsley installs the interpreter - see the docs if you want to use it as a library.

high-level goals

  1. a lightweight Scheme implementation...
  2. that compiles to WebAssembly...
  3. usable inside of a larger application without making too many sacrifices...
  4. that is modular and extensible...
  5. but includes enough definitions to be useful out of the box.

on the horizon

  • improve test coverage
    • More tests from SICP
    • Better coverage of the standard library
    • Example crates
  • (eventually) R7RS compliance
