stacker

A simple domain specific language in Racket. This is part of the excellent book Beautiful Racket, which I would highly recommend checking out.

Usage

The entire language definition is in stacker.rkt, so to use create a new file with:

#lang reader "stacker.rkt"

You can then add integers and addition and multiplication operators like:

5
8
+
6
*

Functional Rewrite

The program was rewritten in a functional paradigm in funstacker which can be used in the same way:

#lang reader "stacker.rkt"

5
8
+
6
*

Stackerizer

stackerizer is a program that converts stacker code into S-expresssions and can be used:

#lang s-exp "stackerizer.rkt"

(* 1 2 (+ 3 4 (* 5 6 (+ 7 8 (* 9 10)))))

This will create stacker code like:

8
+
7
+
6
*
5
*
4
+
3
+
2
*
1
