[Cuis-dev] getting a Squeak VM for macOS

[Mark Volkmann]

I solved this by creating the following shell script in my PATH that I
named "cuis":

#!/usr/bin/env bash
# Runs a file containing Smalltalk code in headless mode using Cuis
Smalltalk.

if [ $# -ne 1 ]; then
  echo usage: cuis {file-name}
  exit 1
fi

CUIS_DIR=$LANG_DIR/smalltalk/Cuis-Smalltalk-Dev
VM=$CUIS_DIR/CuisVM.app/Contents/MacOS/Squeak
IMAGE=$CUIS_DIR/CuisImage/Cuis7.1-6452.image
$VM -headless $IMAGE -s $1

As an example, I created the file "command-line.st" containing the
following:

| stdout |
stdout := StdIOWriteStream stdout.
stdout nextPutAll: 'Hello, World!'; newLine.
Smalltalk quit

To run this I just enter "cuis command-line.st".
