Hi,
Ideally what I'd like to do is launch an executable (a Java application, typically invoked through a batch file) that listens for user-typed commands on stdin, and produces console-style responses. I'd like to throw commands at it from Squeak, listen for the corresponding results, then eventually shut it down.
You might try the ProcessWrapper package. We tried it with the image and vm in http://ftp.squeak.org/3.7/win/Squeak3.7-current-win-full.zip on vista. You can use it like:
p := ProcessWrapper new useStdout; startWithShellCommand: 'cat'; yourself. p writeToStdin: 'foo'. (p next: 3) = 'foo'
It's available here: http://www.squeaksource.com/ProcessWrapper.html
Cheers, Balázs
