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.
- 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)
- Make
- New language features using Crystal's semantics
- Algebraic data type
- ...
- Install
crystal
command - Run
shards install
for installing dependencies - Run
crystal build /path/to/Crisp/crisp.cr
to build an executable (add--release
for the release build) - Put the built
crisp
executable in a$PATH
directory
Please see mal test cases for now.
- macOS or Linux
- Crystal 0.33.0 or later
