Hi,

We didn't expect to be found yet :). But well...we are actually working on a second revival of the SqueakNOS project. Hope to give news in the mailing list soon, but we are still far from having something working with all the new stuff.

Concerning submodules, yes there are plenty of arguments for and against. I've been using them successfully in some projects depending on the Truffle/Graal platform. Nonetheless, in case we managed to make progress and the community is interested on the results, for sure we will be open to discuss about this.

Best,

Guido. ��

In the network graph hovering over charig/2-March commit I see a new
platform Nopsys added for SqueakNOS.

Thats cool !!!�� It'll be great to see this work with OpenSmalltalk.
However I notice its been added as a submodule.

Submodules bring additional complexity, so I thought there should be
some discussion on this topic.
Here are a couple of balanced introductions to submodules...

And a couple of cautions about using them...

Guido & Javier,
Have you used submodules successfully elsewhere?
Could you discuss your strategy using a submodule for the platform
code rather than adding directly into the opensmalltalk-vm repository?

I see your parent repository includes opensmalltalk-vm as a submodule
similar to how I *thought* Pharo was doing it, but wait on comment
from Esteban. .

�� [H] https://github.com/charig/Nopsys/blob/master/.gitmodules
So it seems�� platforms/Nopsys�� is a sub-sub-module.

Esteban,
I thought that you were using submodules to incorporate
opensmalltlak-vm into the pharo-vm,
but I can't see a .gitmodules file there.
�� [I] https://github.com/pharo-project/pharo-vm
So did you do it another way, or am I missing something?
Could you report your experience with adding opensmalltalk-vm into the
pharo-vm repository?

cheers -ben
