Re: New OS to use gnustep!

[Gregory Casamento]

Hi Johannes,

I agree this is exciting and wonderful news!

I am excited about the prospects which collaboration will bring.  I would love to talk further and see what we can do to make GNUstep everything you need it to be.

I am working on an Opal/CoreGraphics backend.  Time constraints and a new release of Gorm (GNUstep's Interface Builder) coming up have prevented me from devoting as much time as I would like to it.   I also think that Fred and Ivan are planning on working on this as well.  I should get back to it by Wednesday/Thursday since I am planning on making a Gorm release either tonight or tomorrow.

Hi,

That's really awesome news!

We have a CoreGraphics implementation, mostly written by Eric, called Opal, but it's not integrated.  Ivan also implemented a significant amount of CoreAnimation.  Unfortunately, neither of them are integrated into the rest of the system.

The first step is probably to implement a back end using Opal.  This would take the Display PostScript calls and call the CoreGraphics equivalents instead.  Once this is done, you can mix CoreGraphics and AppKit drawing calls into the same context.

Integrating CoreAnimation is a bit more tricky.  The current back end interface doesn't have a notion of layers.  This would need to be added, along with some ability to have different rendering targets for different contexts.

Once that's done, there is room for some optimisation.  For example, we should be able to draw views in different layers in parallel and cache the result so that we don't need to redraw the entire view hierarchy.

I think Gregory has done a little bit of work along the lines of integrating Opal with the back end, so maybe he can comment.

We're planning on having a developer meeting in Cambridge, probably at the end of June: it would be great if you could send someone along.
