Well you'll find that in the FFI calls in Sophie for doing macintosh file navigation services.

Yes cleaning a bit would be good because with all these numbers and configurations this is not easy to follow.

[Pharo-project] Good FFI examles?

by Schwab,Wilhelm K

Hello all, I am slowly getting access to metadata that I need to use to create structure definitions. Are there any good examples of FFI with complex structures, particularly with structs containing other structs as fields? Bill

Ok, well I've not compiled the freetype plugin for V5.x yet, so whatever is happening it's not using freetype. Someone will need to decide if the bitblt override plugin should be part of the base system? There seems to be lots of confusion about what smalltalk software, which VM version, and if it's using an override BitBlt plugin. Maybe someone can detail the choices and decide which is the most optimum for Pharo. For testing purposes I *believe* you can run the V5.0 VM on powerpc, or on MacIntel set use 32bit mode in get info. Then included the plugins as shipped with the 4.2.2 VM. You still might need to confirm the 32bit FreeType plugin gets loaded. The V5.0 Vm has the latest bitblt changes from VMMaker, but that might be different than the ones in the older BitBlt override.

It seems that with your setup the FreeType fonts are rendered without subpixel AA. I use the Mac VM, I think with the extra BitBlt plugin, and they look better.

[Pharo-project] Help with Metacello configurations for external packages!!!

by Mariano Martinez Peck

Hi folks! We started to create Metacello scripts to build Pharo images. In order to do this, we need the configuration of the external packages that are load in Pharo images. For those who know a little of Metacello, we need the ConfigurationOfXXX where XXX is the external project. The best is that the maintainer of a project create this class with the necessary information. You may know the packages that must to be loaded, in which order, which dependencies, what is Pharo specific, etc. If you didn't know anything about Metacello, don't worry. It is easy. You can read a good tutorial: http://code.google.com/p/metacello/wiki/Tutorial So, I will list the projects and if you think you can help us with a package, please let us know. The projects are: For the dev image: - RoelTyper - NewInspector - shout - rb - ob - EnhancedOB - OCompletion - Nile - autoMethodCat - PharoMorphicExtras - PharoSound For the web: - KomHttpServer - Seaside - slime - rsrss - magritte - pier - pieraddons I am not sure if we can do the web right now. Maybe it is a good idea to start first with the dev image and when we have enough knowledge we take also the web. So....any takers ? Thanks Mariano

Re: [Pharo-project] Protocol extension proposal: Boolean>>asBit ?

by csrabak＠bol.com.br

CÃ©drick, I understand the diplomacy of the suggestion and I think it sounds like an interesting compromise. Before we jump at it, let me ask some questions: Does a class called BitNumber exists in the present (core) Pharo hierarchy? Does it makes sense to add a class like this? Which behaviour for BitNumber is not already subsumed by Number? my .0019999... -- Cesar Rabak Em 06/12/2009 11:36, CÃ©drick BÃ©ler < cdrick65(a)gmail.com > escreveu: 2009/12/5 <csrabak(a)bol.com.br> I understand the motivation and the implementation, but IMNHO the name of the method should be #asSmallInteger or if you want more general #asNumber. Why not #asBitNumber ? Returning 1 or 0 is not the same thing as returning a bit, except if we agree on creating a class called bit where the operations on it abide to what it is expected for a bit. my .019999... CÃ©drick
