Crisp

Crisp is one of Lisp dialect which is based on mal and implemented with Crystal. This project is a toy box for my dynamic language ideas.

So Many Tasks

• Refactorings
  • Make is_a? guards more elegant
  • Import test cases from Mal
  • Add CI
  • More OOP (evaluator)
  • Use standard readline implementation
  • Better lexer and parser
  • Add examples
• Add more language features using Crystal's semantics (e.g. union type)
  • ...

Installation

1. Install crystal command
2. $ crystal run /path/to/Crisp/src/crisp.cr

Development Environment

• OS X
• Crystal 0.7.1
