[Pharo-project] Morphic 3, Cuis, Simple Morphic and Esug's sponsoring

by Juan Vuletich

Hi Folks, All what Stef said wrt these issues is correct. I just want to (perhaps) make some detail clearer. Esug agreed to sponsor Morphic 3 about one year ago. At that time I expected to have a working and usable system by the end of this year. This is not going to happen. Main reasons are: 1) I underestimated the effort. 2) Inflation and other issues meant I needed to make more money that I was currently making. So I had to reduce the hours I devote to volunteer work to spend them in paid work. 3) I failed to get sponsors for this project outside the Smalltalk community (although I did try). 4) Some of the ideas in Morphic 3 are novel enough that I need to protect them from being patented by others from, before disclosing them. I don't like software patents, so I believe the best way to do this (and get more people to know these ideas) is to submit a paper to a journal such as ACM Transactions on Graphics. This will obviously require additional time. So work on Morphic 3 is not stopped, but right now it is paused. It seemed to me that instead of just telling Esug "I'm sorry, but you'll get nothing by the date I promised results", I could do a more practical, down to earth contribution to the Smalltalk community in return for Esug's support. I believe that many in the Pharo community share my opinion that the current Morphic implementation is obfuscated, that it is too hard to write applications with it, and that it is too hard to fix bugs and evolve it. The Morphic implementation in Cuis is the main result of many (I guess about 6) years of part time work on simplifying the system. I think it could be of great value for Pharo, and an enabler for evolution. So, I did a request to Esug, to deliver this, naming it "SimpleMorphic", ready to run in Pharo, instead of Morphic 3. Esug approved it, and I thank them for this. SimpleMorphic is the result of this. I started by extracting the Morphic in Cuis. This was not trivial, as I had to think carefully where to draw the line between what I'd migrate to Pharo and what I'd use from Pharo. Then I adapted it to some differences between Cuis and Pharo, and also tweaked Pharo to enable using alternative UIs. I worked about 80 hours on this and delivered this week. After all this, I think it is fair to say that Esug sponsored Cuis as SimpleMorphic is part of it. I hope this helps and does not add confusion. Cheers, Juan Vuletich

Re: [Pharo-project] The next milestone reached!

by Pavel Krivanek

Hi Hilaire, I do not think that PharoCore image generated from PharoKernel will be better for your needs. It is not significantly smaller, it has almost the same code base and bugs are common because the original image did a lot of forgotten ad hoc initializations. -- Pavel On Sat, Nov 6, 2010 at 7:44 PM, Hilaire Fernandes <hilaire.fernandes(a)gmail.com> wrote: > Pavel, I would like to be your first user.

[Pharo-project] PharoKernel #12229

by Pavel Krivanek

Hi, I uploaded an updated version of PharoKernel. It is now able to load all PharoCore packages (resultant image included). https://gforge.inria.fr/frs/download.php/27904/PharoKernel-1.2-12229.zip If you want to use DejaVu fonts, uncomment in the file initCore.st this lines: Gofer it squeaksource: 'DejaVu'; package: 'DejaVuBitmapFonts'; load. (Smalltalk globals at: #DejaVuHolder) installFull. StandardFonts restoreDefaultFonts. Please check the generated PharoCore image and open issues for errors because it shows that the packages are missing some initialization code. Cheers, -- Pavel

Re: [Pharo-project] Fwd:Dr.geo en Arabe

by YossiDM

I've had problems with Hebrew fonts which should fall in the same problem space. I just tried some true type ones and the glyphs don't show (same fonts work just fine in eclipse and visual studio). Maybe a bitmap version would work. In any case, it's hard enough getting right to left working in my experience. I don't believe it works particularly well in morphic and in the editors to be useful and you end up being reduced to cut and paste with strings (assuming you can get the string text to even display correctly). I've fooled around with unicode and utf-8 without much luck, but perhaps someone more familiar with Pharo internals can come up with better internationalization solutions. Also keep in mind there are both specialized keyboards and ones that just map font glyphs based on querty, and also overlays. Most of this comes from the host OS of course - check it out on Mac OSX, lots of settings here, but nothing I've tried works with Pharo. -- View this message in context: http://forum.world.st/Fwd-Dr-geo-en-Arabe-tp3029996p3030364.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Re: [Pharo-project] Fwd:Dr.geo en Arabe

by Henrik Sperre Johansen

Disclaimer: I'm not familiar with arabic. I think writing right-to-left does not work, so editing would probably not. Also, letters containing multiple glyphs will probably fail to be composited correctly. The best bet is probably to load up a FT-type containing arabic glyphs and see how far you can go from there. (And report bugs along the way) Cheers, Henry On 06.11.2010 14:47, Hilaire Fernandes wrote: > hanks Ahmed! > > A request. > Is it possible to have Arab language under Pharo? > > Hilaire > > -------- Message original -------- > Sujet: Dr.geo en Arabe > Date : Sat, 06 Nov 2010 13:29:40 +0000 > De : Ahmed Mansour<atphalix(a)inbox.com> > Pour : Hilaire Fernandes<hilaire.fernandes(a)gmail.com> > > > > Bonjour Hilaire, > Si joint la traduction de Dr.Geo II en Arabe, j'ai testÃ© uniquement sous > Etoys vu qu'il a le support de Pango (indispensable pour le rendu de > script complexe), est-t-il possible d'ajouter le support de Pango Ã > Pharo dans une version prochaine? > > Cordialement, >

Hi, I was more hoping from a reply from Juan or someone that knows the details actually :).

ESUG was supporting Morphic 3 (a new proposal) of Juan. Now it occurred that Juan realized that he will not be able to deliver what he wanted. So After discussion one idea was to get simpleMorphic (not lighMorphic) a simpler version of Morphic done by juan for Squeak and Pharo.
