Marble

A simple, interpreted, toy programming language in Haskell.

My interest in parsing and parser combinators is probably clear from some of my previous projects. I wanted to explore the same in haskell with monadic parser combinators and go the extra mile by also implementing an interpreter for a programming language.

I'm planning on extending this language further as I go and work on different projects. A tentative roadmap can be found below.

Usage

Using cabal

cabal run marble -- ./examples/proto_09-10-2022/fib.mrbl

Roadmap

• Monadic parser
• Monadic interpreter
• Make interpreter executable to run programs
• Add location context to both parsing and interpretation for better error messages. Plus improving error messages
• Separate out the parser combinators into their own parser library
• Add container types (Lists and Maps)
• Add garbage collection
• Add static types and a static type checker
• Turn this into a compiler that compiles to some bytecode
