Runner script from John

[lassik]

Thanks for all your work and for the explanations. In (small) return, here's a dinky shell script based on the one I used when I (tried to) keep all the Schemes listed in ImplementationContrasts installed locally through many changes of machine. I have it installed as /usr/local/bin/schemers, but of course anywhere on your PATH will do.

When run without arguments, it lists all available "schemers" images in alphabetical order. When run with the name of a container, it runs that container interactively. When run with "-a", it runs all containers interactively, one by one. This makes it easy, given a snippet of Scheme, to test it on many implementations by pasting it into each REPL in turn.

#!/bin/sh
if [ -z "$1" ]; then
  docker search schemers | sed 1d | sort
elif [ "$1" = "-a" ]; then
  for s in $(docker search schemers | awk -F '[/ ]' '{print $2}'); do
    echo '========================================================'
    echo "                         $(echo $s | tr '[a-z]' '[A-Z]')"
    echo '========================================================'
    docker run -it schemers/$s
  done
else
  docker run -it schemers/$1
fi
