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-string.scm - string utility functions
  • lib/ps-vector.scm - vector functions based on SRFI-43
  • 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

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://gitlab.com/flatwhatson/prescheme-demo.git
cd prescheme-demo
guix shell -m manifest.scm
make
