Lisper

A tiny scheme interpreter in Haskell

Getting started

$ brew install haskell-stack
$ gem install watson-ruby (optional)
$ git clone https://github.com/jaseemabid/lisper && cd lisper
$ stack build
$ stack test
$ stack install

Stack installs a binary called lisper into $PATH.

REPL

Lisper has a simple shell.

$ lisper
λ (cons 1 '(2 3 4))
(1 2 3 4)
λ (define (add a b) (+ a b))
<λ add >
λ (add 10 20)
30
