[Pharo-project] NB squeaksource comits
by Ciprian Teodorov Dec. 11, 2012

Dec. 11, 2012

Hi Igor, sorry for bothering you again with this issue but again somebody (squeaksource ;)) removed me from the commiters of the NB project. Now I have two proposals, a very small one: removing the asm int3, and decrementing the callback counter in #generateCallbackLeaveCodeFor:leaveAddr: so that the vm does not crash on callback error case. Secondly, I have converged to an implementation of NBExternalEnum (using SharedPool) which I think it is cool, and I wanted to share it with you. Maybe you like it... maybe you don't ... ;) Cheers, -- Dr. Ciprian TEODOROV IngÃ©nieur DÃ©veloppement CAO tÃ©l : 06 08 54 73 48 mail : ciprian.teodorov(a)gmail.com www.teodorov.ro

Ok it seems it was just a corupted download, everything seems to work fine now. I have even tried the Nativeboost-Cog build that works too. Thanks everyone for their help and clarifications.

Re: [Pharo-project] How to manipulate HandMorph's position?
by Fernando Olivero Dec. 10, 2012

Dec. 10, 2012

HandMorph is only drawn when its carrying another morph. What you see in the screen is the "hardware cursor", maintained by the vm. This separation was done for efficiency reasons, when drawing Morphic. This is why you evaluate stuff like Cursor wait showWhile:[], to alter the appearance of the "hand/cursor", instead of changing the HandMorph directly. So what you are doing by sending the message above is simply positioning a hidden morph, the hand, at a 10@10. Maybe, try to see if you can position programmatically the Cursor instead.

[Pharo-project] How to manipulate HandMorph's position?
by Carla F. Griggio Dec. 10, 2012

Dec. 10, 2012

Hi everybody! I'm trying to implement some Kinematic Templates<http://hci.uwaterloo.ca/sites/default/files/uist_madness_kin_templates.mov>in Pharo for a course assignment. For that, I'm trying to modify the position of the HandCursor, but trying to evaluate naive messages like: ActiveHand position: 10@10 leaves me nowhere. Is there some black magic I need to know about the HandMorph in order to manipulate it's position they way I want? Thanks! Carla.

[Pharo-project] Athens, Nativeboost and Igor's gray hair
by Esteban Lorenzano Dec. 10, 2012

Dec. 10, 2012

Hi, Last week I've been sick, and because of that I've been bored. To get some fun I started to learn NativeBoos and Athens (and to stress Igor's patience on explain things :). After all, I prototyped a couple of examples that I think are fun: 1) AthensPlayground. This is a workspace prepared to fast-prototype athens animations (taking the same idea of http://www.processing.org/) You can see a video of the (for now) results here: http://youtu.be/NaR_fyk3qq4 I think it can be a good addition for people willing to do some animation work :) 2) After that, of course I was very happy, but I thought "why to stop there? now I want more!" and so, I made a quick search about physics library and after a couple of hours I made a (very primitive) Chipmunk usage framework and an even more primitive and simple "game engine like" framework, to mix both Athens and Chipmunk library. A video of the results can be found here: http://youtu.be/ZK-JlbeN09A Pretty cool, isn't? Ok, I know... is not like I invented the hot water, all of this was more or less present in morphic... but is cool to have real examples on using external libraries (also, physics are really hard to simulate, so... better to use something already existent). If you want to play with it, you can go to: http://smalltalkhub.com/#!/~estebanlm/Storm Enjoy :) Esteban

That was an obvious one, I should have guessed it . I did try it , it report the same permission denied error. I will continue searching for a solution for it. Again thanks for helping me out. Regarding audio or music synthesis coding I am not interested in doing that myself because its a lot of work. Supercollider is a live coding enviroment , its basically a server app that can be controlled through socket messages to be precise, the osc protocol. Its a tool used by professional musicians and is both extremely flexible and very fast. http://supercollider.sourceforge.net/ Doing what supercollider does in smalltalk would be an insane amount of work at least for me. I try to minimise coding as much as possible and I am a big fan of code and tool reusageÂ and repackaging. So the only thing I am going to do is just make the gui for it. Of course my gui will offer limited access to the power of supercollider. I like to note here that I plan to avoid as much coding as possible with Ephestos because I know such a big project can become insanely demanding, so I don't want to reinvent the wheel. Gui designer wise, its funny because the part that does not interest you is exactly what interests me. I want to target with Ephestos not experienced smalltalk coders but users that have not done any coding in their lives and they are scared of starting it. I want Ephestos to be the 6 minute solution , 6 minutes will take you to figure out how to do something in it. So my goal is "Morpheas" a cut down version of Morphic, simplified, very well documented and very easy to use and understand with its own designers. I am considering using Athens and NBOpenGL for Morpheas will see how that goes. I really like Athens. Still I will try my best to build Morpheas on top of Morphic so you can still have your pie and eat it too.Â You are correct though most GUI designers out there do suck , but there is one exception ... Delphi / Lazarus and I am a huge fan of it. Unfortunately or fortunately i prefer dynamic languages like smalltalk and python from object pascal. Hence why I am trying to code for Pharo and not Lazarus. For the time being my sole focus is the interactive tutorial tool and figuring out how morphic works. Then will start working on Morpheas , which together with Proteas (IDE tools ) and Orpheas (the supercollider front end) form Ephestos. I dont want to overwhelm myself so I will just work on a single tool at a time and take it slowly step by step. But I will definetly keep you informed of my progress.Â ________________________________ From: Goubier Thierry <thierry.goubier(a)cea.fr> To: dimitris chloupis <thekilon(a)yahoo.co.uk> Sent: Monday, 10 December 2012, 17:25 Subject: Re: [Pharo-project] Unable to run pharo on Ubuntu 12.10 Le 10/12/2012 16:14, dimitris chloupis a Ã©crit : > Thanks for helping me out > > pharo -v > > pharo: command not found Ok.

Ok. A good suggestion then is, for audio synthesis and music composition, look at the work of Steven Travis Pope : he's done music synthesis tools in Smalltalk for a very long time (I met him in Paris around 1997/1998 and his tools were already impressive). For the GUI builder, I'm not too keen on that personaly. A gui builder is often a dumbing down of the underlying GUI toolkit, to be usable and general enough, and this is particularly true of Morphic which is a lot more advanced than Pharo shows it. In a way, the original Morphic has an integrated GUI builder... and the code is still there in Pharo and the GUI, but hidden. Still, I believe Spec is probably looking for help for that GUI builder. And, if I get to start it, I may propose some simpler Morphs which would work wonder with a GUI builder.

no I was not aware that it could not be done, worked fine for Macos (I am mostly a mac developer which is what I use at home, I use pcs only at work)Â so I assumed the same applied for Ubuntu I installed the package , still its unable to run it. Getting the same error I used the second answer to this question as a guide to install the package --> http://askubuntu.com/questions/107230/what-happened-to-the-ia32-libs-package " If you get that error, try: sudo apt-get update Then try it again: sudo apt-get install ia32-libs" I just did a fresh install of 12.04, that package is still available in the repositories.
