Nevertheless, part of Athens need to be polished and from my pov it looks like it is not the priority, and I am disappointed by that. But again my vision of the situation is from outside, so definitely biased. Regarding Blender and Pharo: don't you want to control Blender engine from a Pharo model. I mean why do you want to bother with graphics and animation rendered by Pharo, it is not what Pharo is good at. What I will do is design the model in Pharo then drive Blender from it. That should be eaiser and benefit from the two worlds. Am I wrong? Hilaire -- Dr. Geo - http://drgeo.eu iStoa - http://istao.drgeo.eu

Yes, but it is clear that sometimes it is just too much work. e.g we can (by definition) not put everything new in Pharo4 in Pharo3. So this should be seen as a âbest effortâ rule... Marcus

Yosemite & Pharo

by Yuriy Tymchuk

Hi pharoers, so Iâve installed Yosemite beta and: 1) there were no problems with Pharo by now 2) sometimes Yosemite lags in general (on rich 3D graphics for e.g.) and battery life is worse. 3) the most important thing that Iâve noticed: there are no black bars if full screen mode. Is an improvement in Pharo, or just how Yosemite works? Cheers. Uko

About renaming API methods

by Marcus Denker

Hi, In case we rename methods that are used as part of the public API, I propose to do 1) add the same API to the current stable version (today this would be Pharo3 2) add a rule (in a âPort Pharo3 to Pharo4â category that finds the needed senders (if possible even with a transformation) Then depending on the use and importance -> deprecate the old API right away or -> just tag it as âto be deprecatedâ one version later or -> keep the old as âcompatibilityâ This should make it possible to clean up API (e.g. when there are typos in the selectorâ¦), while not disturbing users to much. *And* it will be possible to have affected code running both in Stable and Development. (This should not be a strict rule, more a âbest effortâ one, and there will always be cases where we can not do this or where it is not needed). Marcus

Thanks for that, I'll look into it. Rubric looks definitely nicer that the old thing. It opens a lot of doors and may allow me to do the little I wanted to do when I started using Pharo.

Re: [Pharo-dev] The Dilemma: Building a Futuristic GUI for Ephestos

by kilon alios

Blender indeed has its own GUI called "Ghost API" which is OpenGL 1 based in order to work even with very old GPUs. Yeap I agree with your post 100% this is why I said I love Pharo and I prefer it over any other language I have coded in. I can certainly understand your frustration with Java . I also envy you that you can use Pharo to make a living maybe I can do that one day too :) I also agree there is no such thing as silver bullet. It also depends on what you want. For example I could port Blender source base as a library to pharo with NB bindings but that would be a massive amount of work and not the same as just making small contributions to Blender. I think in the end, whether you like a programming language or not you have to be realistic about your goals and what you ask from the language. I tried to fit Pharo into my workflow but just it does not fit. The good news is that at least I will be avoiding C++ for now as the part I am most interested in Blender, sculpting is coded in C. But I dont give up on pharo just yet completely, I just said it wont be anymore my main platform. I see no reason why I should not contribute a few bug fixes or enhancements to pharo per year. I would also like to finish porting the 5th chapter of PBE to Pharo 3 at some point. So no worries I will be around, just much less active :) And will definetly follow the mailing list with great interest :) On Mon, Sep 15, 2014 at 2:24 AM, phil(a)highoctane.be <phil(a)highoctane.be> wrote: > FWIW, Blender has its own UI toolkit.
