The purpose of this repository is to organize all of the Scheme code I write while I go through Structure and Interpretation of Computer Programs.
All of the code here can be run on DrRacket which is freely available on any platform.
Download and install DrRacket.
Follow the instructions to set up Scheme for SICP.
Here is an example to include another file into your program.
Lets say you have a file called lib.scm:
#lang racket
(define (sq x) (* x x))
(define (cube x) (* x x x))
(provide (all-defined-out))
Let's go over this, I have a file with some functions that I'd like to call elsewhere. The last line (provide (all-defined-out) is a method in Racket to make public all of the functions defined in the file. This method is only available in racket which is why we don't use #lang sicp here.
Now, to use the above program in another file, let's say test.scm just include the line (#%require <relative path to file>):
#lang sicp
(#%require "lib.scm")
(sq 5)
