Re: [Pharo-project] Fwd: about setting and preference.

by Alain Plantec

Hi all, I've changed the new setting implementation. The new proposition is attached. I think that this implementation is in sync with Lukas remarks; and yes, I think it is much better now, thanks! I also removed PragmaHandler and SettingHandler classes as Stephane suggested. It temporarily includes several (stupid) examples for testing purpose. Comments have not yet been changed. I will do it asap. Remarks, comments etc are welcome. Cheers Alain Lukas Renggli a Ã©crit : >> - A setting with value is an instance of SettingValue or of one of its >> subclasses.

Re: [Pharo-project] Status of Alien FFI

by Schwab,Wilhelm K

I hit a similar problem with ODBC on 64 bit systems. One caution though: we can't completely lose control of the size when fixing this. One might need to read something written by a 32 bit system on a 64 bit one. Just as with int and DWORD, there needs to be a way to ask for the proper size for the platform or for a specific width. I once saw a system (then thinking 16/32 bit) where they had the platform and fixed types backwards, but that's another story ~:( Bill Saludos, Fernando Il giorno Sep 16, 2009, alle ore 8:37 PM, Ken Treis ha scritto: > * I'm creating a partial Alien library for GemStone so that I can use > the CairoGraphics package in both Pharo and GLASS.

Re: [Pharo-project] Status of Alien FFI

by Schwab,Wilhelm K

I hope I'll remember to watch it later, but this type of thing has been going on for a long time. I remember a friend of mine getting excited about a thing called Actor. There was this weird thing called Smalltalk, and these guys (Whitewater Group??) came along and "fixed" it by giving it C syntax. Not meaning to bash my friend; just pointing out how long people have been trying to take part of Smalltalk without really understanding the bulk of it. To be fair, look no further than Croquet for some blame here. They insisted on making an immersive 3D system rather than factoring it to provide whatever level the user might want. Maybe later we can start up a group to pull their retained mode framework into Pharo to serve simulation and gaming projects. Let's leave Tweak behind though.

The guy who narrating the video, came to conclusion, that its cool to be able to simply copy the code snippet & run it on different host/project without recompiling C++ stuff, also mentioned that operating on entity level (by scripting particular object(s)) makes life much easier, especially when project complexity grows and grows bigger.. I just wonder , if Lua is so good for him, what would he say, when discover the smalltalk, and especially its environment, which inherently allows to work with objects in real time without edit-recompile-run cycle. :) 2009/9/21 Schwab,Wilhelm K <bschwab(a)anest.ufl.edu>: > Good luck.

I can only speak for myself here, but if Python were enough, I'd have switched already. So either we are to believe that Pharo will grow too big for its own good, or M$ will glossy-ad us out of existence. Let's just build what we want and let the other half do their own thing. -----Original Message----- From: pharo-project-bounces(a)lists.gforge.inria.fr [mailto:pharo-project-bounces@lists.gforge.inria.fr] On Behalf Of Lawson English Sent: Sunday, September 20, 2009 9:28 PM To: Pharo-project(a)lists.gforge.inria.fr Subject: Re: [Pharo-project] Status of Alien FFI Not meant as a promotion of C# 4, just an observation about MS marketing power and R&D resources...
