Creating an SDL (OSWindow) window without showing the pharo interface

Does anyone know how to get an OSWindow window to open from Pharo without
showing the pharo IDE?

I thought the headless VM might do this.

So I downloaded the latest headless VM and Pharo 9.

Then if I issue the command line
/
pharo-ui Pharo.image eval OSWindowWorldMorph new open/

I get an SDL window but also the pharo user interface which I don't want.

But if I try

/pharo Pharo.image --no-quit eval OSWindowWorldMorph new open/

nothing happens. Pharo runs but nothing shows up. I expected just to get the
SDL window.

Can this be done in pharo? Anyone know the technique?

Russ -

The trick is to put the --no-quit after the eval not before it. I was
putting it in the wrong place.

This should work:

./pharo Pharo.image eval --no-quit "OSWindowWorldMorph new open"

This works with the latest headless VM and Pharo 9.

Hope this helps.

Yes, pharo is the script that starts the headless VM without the IDE
(pharo-ui is the script that starts the headless VM with the IDE).
Pharo.image is the default Pharo 9 image - obviously you can use your own
tailored image.  

I downloaded the headless VM and the latest Pharo like this -

curl https://get.pharo.org/64/90+vmHeadlessLatest | bash

This installed everything into a folder. i opened a terminal on the folder
and issued the command line

I'm on Linux - not sure how this all works on Windows or Mac.

By the way - I could not get this to work from Pharo Launcher - perhaps
because I was using an older Pharo 9 - but despite editing the configuration
in the Pharo Launcher nothing worked.

Hope this helps.
