Hi,


Thank you for all the interesting links, most of all to the SqueakShell! It is really cool, but however, it actually does not solve my corner.


@Fabio:

Exactly. If you run a simple script such as [HelpIcons squeakIcon writeOnFileNamed: 'testicon.png'] in headless mode and testicon.png already exists, the execution will be halted and the VM is waiting for a user interaction that will never happen. It would be much nicer to get a prompt via stdout + stdin to answer.


And even if the VM is run in a read-only shell, you would at least know why it does not continue to execute. For example, this would be helpful on smalltalkCI - if you had not caught all ProvideAnswerNotifications in your tests, you would basically have no hint why you get a timeout.


I know Squeak is primarily made for use in a VM window, but nonetheless, I would love to have an implementation similar to this one for Pharo<https://github.com/StephanEggermont/pharo/blob/development/src/UIManager/CommandLineUIManager.class.st#L104> in Squeak.


Best,

Christoph

We discussed some stuff around this topic back in May '19 relating to "Running Squeak fro ma unix shell script file with #! squeak..." (including the spilling mistook).

And don't forget CommandShell (http://map.squeak.org/package/2c3b916b-75e2-455b-b25d-eba1bbc94b84), OSProcess (http://map.squeak.org/package/812c9d14-5236-4cad-82ea-cc3e3837e30d), and Eliot's simple exemplar REPL thing (https://github.com/OpenSmalltalk/opensmalltalk-vm/blob/Cog/image/LoadReader.st & https://github.com/OpenSmalltalk/opensmalltalk-vm/blob/Cog/image/StartReader.st)

I also see that http://www.squeaksource.com/@azqxWT7-o5bjyYS2/vd0deS9q claims to include a REPL package (never tried it, see also http://gulik.pbworks.com/w/page/7760030/REPLServer)

And I'm sure Craig has done something related but I simply cannot get google to find it right now
