Re: [Pharo-project] Anyone mixing Matlab/Octave and Pharo?

by Nicolas Cellier

Hi Bill, I tried to port Smallapack - a Smalltalk interface to Lapack - into squeak but never finished it... google it if you have time to loose. It works on VW and Dolphin yet. In squeak, I have chosen to use FFI, but maybe it would have been more secure to generate a VM plugin... As you may know, Lapack is a very stable robust and public domain algebra library used for example in Matlab, Octave, Scilab, etc... It is my number one choice far above gsl. Now the idea to go thru octave interpreter might work as well. You may however loose some time in interpreting inputs/outputs back and forth... Depends on the volume of I/O you are planning. I presume there is also an access possible to an octave engine doable via plugin/FFI, passing directly Octave objects to Octave functions...

Â I have some seriously old Numerical Recipes code that I altered and compiled, and more recently have used the GNU Scientific Library. Â All of that is connected to Dolphin, and it will take some time to adapt it to Pharo. Â Even more recently, I found reason to exceed GSL's feature list, and Octave might be able to do the job. > > The first thing would be do the minimum work to get some data into Octave and see how it does. Â Ideally, I would want to pipe data into Octave, get results from it, and then do some post-processing in Pharo. Â In GSL (dll/so) terms, the idea is to do all of the memory management and algorithm level work in Smalltalk, and the tight loops via the external code, and hopefully to do all of that w/o littering the drive with temporary files. > > Any experience, good or bad, in those directions? > > Bill > > > > > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project >

Yes, I also found that problem, but there must be a way to find it in some place (or there should be) without writing a plugin. >Please, put this into GLMorphic package.

Ok I'll change that, and also I'll try to fix the glitches (at least making the fonts respect the ascend so that the characters are placed in the baseline.

FFI-Examples is bad place for this. Btw, i'm currently in the middle of writing plugin for binding the OpenVG (http://www.khronos.org/openvg/) And your new additions could be useful, because for tests i wanna use the ShivaVG implementation, which expects a pre-initialized OpenGL rendering context...

Accessing the window handle, as it shown in Win32/FFI examples , using activeWindow() function, is not what i like to be depend on. As well as filling the boring PIXELFORMATDESCRIPTION fields is not very easy in smalltalk... :) But anyways, if you did it, it is good, because now, it could work w/o additional plugin. An initialization & windowing stuff can be ported onto another platforms with a bit of pain, but the rest should work as usual because its OpenGL :) > > If you want to try it, you should do > > ScriptLoader loadFFI. > > and then download the GLMorphic-JEP version of GLMorphic package from > squeaksource (after GLMorphic-sig? ).

Especially with font glyphs. I had plans to rewrite the texture/font cache for it, to not use weak finalization. Because i suspect that this is a reason why sometimes textures go wild - because finalization process interrupts UI process in the middle. And this potentially could damade the OpenGL state mechanism, because of out-of-order calls. At time, i implemented it, i was not aware of Squeak's scheduling nuances :) > World fullDrawOn: GLDisplayScreen testCanvas. > > and you'll see. > > Let me know what you think. > > Bye! > > -- > Javier PimÃ¡s > Ciudad de Buenos Aires > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project > -- Best regards, Igor Stasenko AKA sig.

I mean, is correct a class to be abstract depending on the platform? If this is true, ok, I like your solution heheh.

[Pharo-project] Making GLMorphic plugin work in Pharo

by Javier PimÃ¡s

Hi, this is my first mail to the list so hello everybody. I've been trying to make GLMorphic work on pharo and got some useful results. I investigated the plugin that was needed to integrate into the VM and noticed it was really small, so I thought why make this in C if you can implement it directly in smalltalk. Shortly after that I came up with a translation of it (through FFI) so that you can use it with the VM as is. The code isn't something I'd call good, but it works fine (only windows, sorry). If you want to try it, you should do ScriptLoader loadFFI. and then download the GLMorphic-JEP version of GLMorphic package from squeaksource (after GLMorphic-sig? ). I also made some modifications to FFI-Examples, so you may also have to dowonload FF-Examples-JEP from squeakfoundation.org. I'm new to monticello so it wouldn't be strange if nothing got uploaded correctly. Some things work and most looks messed up, specially fonts... try World fullDrawOn: GLDisplayScreen testCanvas. and you'll see. Let me know what you think.
