Hello, Yesterday I wrote on Pharo-users but I was suggested to use the Pharo-project mailing list. I forward my email here, and sorry for cross-posting. I already received some answers, but further hints are appreciated.

by Torsten Bergmann

Lars Bak presents several language virtual machines (Self, Strongtalk, Hotspot), why they matter and how they influenced V8 and Dart. http://www.infoq.com/presentations/Performance-V8-Dart I agree when he states "I like Smalltalk" ;)

[Pharo-project] RE : RPackage by-hand code

by GOUBIER Thierry

Hum. I don't know how to easily reproduce the bug, but you may see the result. Take the last 2.0 image for download, open a Monticello browser, select one of the Refactoring-Tests-* package, do browse package, and look at what's inside the browser. Can also be checked through: ReleaseTest>>testUnpackagedClasses : unpackagesClasses isn't empty. I believed it happened in a RPackageOrganizer initialize in one of the recent updates, but why? It does not happens everytime with my packages: sometimes it's one, another time it's three packages, and yet another time it's none. Esteban has my image, but it seems hard to reproduce.

Bryce 7, Hexagon2.5, and Daz Studio 3D over here :-) Not sure I want Pharo to mix with those... but they make nice Pharo backgrounds for sure. Phil 2012/10/18 dimitris chloupis <thekilon(a)yahoo.co.uk> yeap that would be great because that would mean I could share the same window with blender and that I would have immediate access to all blender functions . But that would require some hackery beyond my level of skill.

Of course visual coding is much more than that, but this is none the less my first step. I try to achieve this with triggering python command via sockets from pharo to blender. Ideally I could generate st methods and classes for all blender python methods and classes. But that is for much later. >> >> Still it could be handy to display 3d blender data in pharo. My vision is that both blender and pharo window will be displayed one next to the other, with the user using the pharo window doing visual coding or procedural generation of 3d objects , materials, textures , particles etc and seeing the final result in blender window. If you are familiar with Softimage ICE this is more or less the field of application for "Ephestos". But still could be handy to do some displaying in pharo as well so that the blender window could be minimised.Â >> >> This is a video with Softimage ICE. Quite interesting even if you are not interested in 3d graphics. >> >> http://www.youtube.com/watch?feature=player_embedded&v=do1kzR6gVYk >> >> That could be extended even to blender game engine , so that pharo via blender can be used to make 3d games. So yeah sky is the limit. But for now , just basic sockets to trigger simple python eval commands and gradually build from there and see how far I can go with this idea. >> >> From: StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> >> To: Pharo-project(a)lists.gforge.inria.fr; dimitris chloupis <thekilon(a)yahoo.co.uk> >> Sent: Thursday, 18 October 2012, 19:56 >> Subject: Re: [Pharo-project] what is your pharo story? >> >> for your information jb did a blender importer and you can play with blender 3d objects in Pharo. >> >> Stef >> >> >> On Oct 17, 2012, at 2:43 PM, dimitris chloupis wrote: >> >> > >> > I am a blender developer , using python to make blender addons. My latest complete one is Gyes and Random Material and Texture Generator. http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/System/Gyes >> > >> > Since I was a child I was dreaming of making a system that would use GUIs like the one that I saw in many spaceship movies, fluid futuristic GUIs that could issue way more complex commands than our modern window type GUIs. It was a childs dream, filed as too ambitious and stored there with the rest of too far fetched child dreams. And it was early this year that I was introduced to Smalltalk. I really like python but it was obvious to me that I needed something a lot more. It was that itch I had to scratch. I was very impressed with morphic and squeak and the whole enviroment and of course pharo. I was looking for a live coding enviroment with an ephasis on visual side and I think smalltalk fit like a glove for me. Morphic fit exactly my lego brick logic, I am a very synthetic person I like to keep things minimal and simple and synthesize complex structures out of them. Its a workflow I follow with my entire life not just coding. >> > >> > So I started a thread in Blenderartists forum ( http://blenderartists.org/forum/showthread.php?250375-A-Visual-Programming-… ) about how people saw the possibility of implementing a visual programming enviroment for blender with a very flexible GUI. I thought it would be one of those threads that none really cared and people would say "we have python why bother with a visual coding enviroment at all, python is very easy to learn" or "why should I care about coding at all I am merely a user".Â And of course I had such reactions but to my surprise the thread just went viral and people seems very excited with the ideas of Ephestos. >> > >> > So we sat down with another developer using Morphic code from a smalltalk coder , that he made for python and pygame and we tried to port to Blender libraries instead. Code wise it went much better in our side , suprisingly enough both he and found Morphic very easy to understand. But we came across some severe bugs and limitations at blender side that make it evident that if I wanted to keep this in python I had to dirty my hands with some C and diving inside Blender source. >> > >> > It also became more and more evident that squeak and pharo already implemented many of the ideas I had for Ephestos, and there was no way I could port all the features both offered to python just me and another coder in our free time. So I did the logical thing. Droped the idea of keeping the project pure python and now I have slowly started to porting it toÂ Squeak/Pharo and I am using sockets to communicate with blender. >> > >> > The goal is of course Visual Coding together with several other ideas I have for RAD. Its not something bound by goals but more an exploration of potential.
