An (outstandingly) partial implementation of Lisp/Scheme based on Write You A Scheme 2.0 ported from Haskell to Scala using pure functional programming techniques with cats, cats effect and cats monad transformers.
It includes an interactive REPL, file system access, and its own, although very poor, standard library.
- Install Java 8+ runtime, Scala lang and SBT build tool - this all can be done through sdk man
-
interpret the file at given path:
sbt "run path <path>"sbt "run path ./src/main/resources/demo/add.scm" ... 3 -
start the REPL session:
sbt "run repl" ... λ: (+ 1 2) 3 -
eval passed expression:
sbt 'run eval "(+ 1 2)"' ... 3
- variable declaration in REPL (!)
- Fix IO bugs, make it more robust
- rewrite to StateT, implement Y combinator
