[Pharo-project] Understanding NBOpenGL
Ok so I tried to learn Opengl ES 2 (and opengl 4) during my eastern vacations because I realised that I dont really need Athens or vector graphics for my GUI , since I will be dealing mostly with 3d graphics anyway. (My project ephestos will be an effort of creating a 3d app for pharo, see also blender) So when I tried to run the demos i get an error with NBMacGLContextDriversupportsCurrentPlatform obviously, for Mac intel-32 only :) ^ NativeBoost platformId = NativeBoostConstants mac32PlaformId My mac is obviously not 32-bit but 64 bit, but I dont know if that matters since pharo is only 32 bit anyway. The bug is also obvious it should be mac32PlatformId and not mac32PlaformId. I correct and proceed and gives me a new error this time in NBMacGlApiglApiCall: fnSpec index: fnIndex attributes: attributes context: contextToRetry ^[ (NBCallFailureHandler for: contextToRetry) retryWith: [ :targetClass :targetMethod | (NBFFICallout targetClass: targetClass targetMethod: targetMethod fnSpec: fnSpec) stdcall; generate: [ :gen | self emitCall: fnIndex generator: gen ] ] ] on: NBNativeCodeError do: [:err :handler | err errorCode = ErrorFnNotAvailable ifTrue: [ Native code is installed, but function pointer not loaded yet. Try to load function and retry the call (self tryGetFunctionPointer: (self class glFunctions at: fnIndex)) ifFalse: [ ^ err pass ]. ^ handler retrySend ]. err pass ] The problem here that NBCallFailureHandler is nowhere to be found. At first I though my NB was lagging behind in version so I download from smalltalk Hub and did ConfigurationOfNativeboost loadStable. it updated without errors but still that class is nowhere to be found. So my question is this, does it really worth it to struggle with NBOpengl or will it better to learn how Nativeboost works and use Opengl myself ? -- View this message in context: http://forum.world.st/Understanding-NBOpenGL-tp4686514.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
Re: [Pharo-project] Understanding Athens
Ok resumed learning of Athens, did look through and experimented with the steps of the tutorial , I think I understand the basics now. Started from a fresh image reinstalled everything and no longer save my image with Athens Tutorial open so there is no segfault.But the error remains.

Re: [Pharo-project] do you know what is this?
Estaban correct me if I am wrong but AFAIK MACOS GUI is based on opengl and it is hardware accelerated. I hear the same applied for Linux GUIs too in large. Anyway, my only objection is the fact that we will have twice the code to maintain and more to worry about. As I said I am on macos , I am a mac developer (not pro) still ObjC never made sense for me since it locks me down to a specific platform. It does however make sense to have platform specific code for providing better and smoother support for that platform. So its definetly good to have and thank you for your efforts. Speedwise , I know the subject on optimisation is a huge one and there thousands of ways to speed up specific code. Its a more a practical one, since not to many people work on athens we need to choose one way that makes life easier for everyone and especially people who develop Athens. Part of the sucess of Cairo is that is an easy to understand little library that is very well documented. I would like to see Athens maintain that. -- View this message in context: http://forum.world.st/Fwd-do-you-know-what-is-this-tp4681962p4682078.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
Re: [Pharo-project] How to browse a selected method in code viewer
Is it a bug ? If I select a class and do alt+b it works , if I select the entire message it does not . For example In Athens-Cairo-Paints packages AthensCairoPatternPaintintialize in line NBExternalResourceManager addResource: self data: handle. if I select NBExternalResourceManager alt+b works and browses the relevant class If I select NBExternalResourceManager addResource: self data: handle. and hit alt+b it does nothing Is that a bug and can you reproduce that bug ? if yes in both accounts then I am more than happy to create the bug report. -- View this message in context: http://forum.world.st/How-to-browse-a-selected-method-in-code-viewer-tp4681866p4682083.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
Re: [Pharo-project] do you know what is this?
Can NB also disassamble code called ? I know that gdb can do this, and since NB generates assembly code for the FFI calls I was wondering if it can disassemble them too. Assembly is definetly not as pretty as smalltalk but can be useful none the less to look at internals. Porting everything to smalltalk is not a realistic or a very useful scenario. Whos is going to port Cocoa to Morphic come on lets see some hands raising :D I see coding more as Aikido , use the force of your enemy ( in this case a big clumsy GUI API like Cocoa , yes I dont like Big GUI apis ) against him. An ObjC bridge and NB seem to fit that role fine to me. -- View this message in context: http://forum.world.st/Fwd-do-you-know-what-is-this-tp4681962p4682112.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Re: [Pharo-project] Understanding Athens
Doru , I am using Pharo 2.0 from the main website , also it does not matter because cairo libraries are looked outside the pharo folder. If you open system browser and go to the CairoLibraryLoadergetLibraryPath (class side) you will see it tries to find cairo libs in '/usr/lib/libcairo.so' . On the other hand there are cairo libs included for the windows version inside the pharo folder. Its kinda wierd that they are not included for macos and linux. Pavel , you mid sharing how you installed 32 bit cairo, because I googled it and I could not find anything on the subject. Thanks. Oh and if anyone can answer my stackoverflow questions i will be more than grateful. I am prepared to contribute to Athens as much as I can and even port mophic to it BUT i need first to understrand what is going on. I have read Cairo documentation and now all i need is to decypher athens so be prepared for a bombarment of questions. -- View this message in context: http://forum.world.st/Understanding-Athens-tp4681820p4681847.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
Re: [Pharo-project] Understanding Athens
Thank you Igor for the clarification. Suffice to say I was never a fan of relying to third parties for dependancies because it ends up in scenarios like this one. Similar reason why I am not a big fan of installing libraries to common paths, though I also understand the need for it. My vote goes into including all the dependant libraries in pharo folder for linux and macos as well. Pavel thanks for the install instructions but I am afraid they dont work for my Ubuntu 12.10 amd64 apt-get install yum was sucessful but as soon as i do sudo yum install cairo.i686 the system replies Setting up Install Process No package cairo.i686 available.

Re: [Pharo-project] How to browse a selected method in code viewer
Ah ok its in there, i did not see it. Why is it not in top ? its seems very important tool to be in a sub menu. Also I have another issue it does not work always, if I select method and choose browser it does nothing but reopens the right menu, the weird thing is that senders and implementors work fine but also reopen the right click menu. In 90% of the cases does not work. Anyone else having the same issues on Ubuntu 12.10 mad64 ? I dont know if this is a AthensTutorial bug , seems some people have it with even do it. I tried Altbrowser from the configurations tool , changed to it and still get same behavior. -- View this message in context: http://forum.world.st/How-to-browse-a-selected-method-in-code-viewer-tp4681866p4681879.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Re: [Pharo-project] Understanding Athens
with the help of Damien via irc I have solved the problem with AthenTutorial, the lib is installed in /usr/lib/i386-linux-gnu/libcairo.so.2 I changed the getLibraryPath to point to the right directory and the tutorial now works fine, Damien also answered my canvas question a huge thank you to Damien :) Thanks all of you for the help too -- View this message in context: http://forum.world.st/Understanding-Athens-tp4681820p4681885.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Re: [Pharo-project] How to browse a selected method in code viewer
ah thank you it works now. Well I am developing a project which I call Ephestos its an ide for visual , live coding for 3d graphics , sound and music for pharo. I started it for blender and python but I really enjoy pharo so I decided to port it. I had several ideas , nothing super original , live documentation, live display of implementors and senders with no need of right clicks , menus and such. If you take a look at LightTable it already implements several of my ideas. http://www.chris-granger.com/lighttable/ http://www.chris-granger.com/lighttable/ if you implement those features then certainly I will be reusing your code. It seems to me that you are very close to those ideas. -- View this message in context: http://forum.world.st/How-to-browse-a-selected-method-in-code-viewer-tp4681866p4681896.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
Re: [Pharo-project] Understanding Athens
Oh Oh not only enabling Freetype does not solve the problem but even saving and quiting and restarting the image the problem remains. So I disabled and renabled Freetype again and save and quit and opened pharo again and this time pharo closes, everytime i try to reopen pharo it closes immediately how I disable freetype without being able to open my image ? -- View this message in context: http://forum.world.st/Understanding-Athens-tp4681820p4681905.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
