Pre-Scheme Demo Code

This repository contains some basic examples of Pre-Scheme code, and a simple Makefile for compiling these into native executables.

These examples are based on the one provided in "The Nearly Complete Scheme48 PreScheme Reference Manual" by Taylor Campbell: https://groups.scheme.org/prescheme/1.3/

Source files

packages.scm - package definitions
lib/ps-utils.scm - utility macros
lib/ps-string.scm - string utility functions
lib/ps-vector.scm - vector functions based on SRFI-43
lib/ps-grid.scm - an ASCII grid data-type
lib/ps-sdl2.scm - minimal SDL2 bindings

hello.scm - "Hello World" in Pre-Scheme, from the manual
append.scm - Yes, you can string-append in Pre-Scheme
vecfun.scm - Showing off Pre-Scheme polymorphism with vectors
recfun.scm - Simple demonstration of records (structs)
btree.scm - Example of a recursive record type
game-of-life.scm - Conway's Game of Life in Pre-Scheme with SDL2
prime-sum.scm - Sum of primes using Sieve of Eratosthenes

The generated C for each of the demo programs is also included, so you can review the code generation without needing to build anything.

How to build

The Guix manifest sets up all prerequisites for building the demos, and compilation is handled by the Makefile.

To build the demos yourself:


git clone https://codeberg.org/prescheme/prescheme-demo.git
cd prescheme-demo
guix shell -m manifest.scm
make
