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, remove global variable, move states into object)
  • Use standard readline implementation
  • Better lexer and parser
  • Add examples
  • More convenient REPL (e.g. completion)
• New language features using Crystal's semantics
  • Algebraic data type
  • ...

Installation

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

Development Environment

• OS X
• Crystal 0.7.1, 0.7.2
