Dockerfiles for various Scheme implementations

Scheme implementations in Docker

This repository contains Dockerfiles that provide various Scheme implementations. They all install a scheme-script or scheme-r7rs wrapper, so that programs starting with the right shebang run straight out of the box.

The Dockerfiles are provided on separate branches so that automated builds on Docker Hub will not be triggered unnecessarily. The builds are available here: https://hub.docker.com/u/weinholt/

Chez Scheme

Chez Scheme in this project is built in a special way that removes the expression editor and therefore removes the ncurses and X dependencies. This is useful when you want to distribute the resulting binary bundled together with your own program, because the result is more portable and only requires GNU libc.

Usage

R6RS

To be compatible with most Schemes, put this at the top of your programs:

#!/usr/bin/env scheme-script
;; -*- mode: scheme; coding: utf-8 -*- !#
#!r6rs

This follows the R6RS non-normative appendix.

The !# token is needed to have Guile stop parsing the #! block comment. The #!r6rs token is needed for Racket to switch to the R6RS language. The mode and coding comment is not strictly needed, but helps Emacs users.

R7RS

To be compatible with the R7RS implementations in this project, put this at the top of your programs:

#!/usr/bin/env scheme-r7rs
(define (main args)
  <your program here>)

This follows SRFI-22.

Implementation notes

Loko Scheme

The loko:base image provides only Loko Scheme and no other user space.
