[Pharo-project] The better debugger support by extending an Object protocol
by Igor Stasenko Sept. 7, 2009

Sept. 7, 2009

Hello guys, i'd like to discuss with you an idea of having a specific methods in Object class for a better and more clever behavior when debugging. For those of you who are using different kinds of proxies, the main problem with them that you should override the #printOn: or #printString methods in order to behave them similar to what original(proxied) object should be, but from other side, especially for debugging purposes, this incurs a major inconvenience, because you often need to differentiate between the real object and object proxy while debugging. Because if proxy behaves similar to proxied object while printing, you can't really make a difference when looking at it. So, i thought that a nice solution would be to extend an Object protocol especially for debugging purposes by adding #debugPrintOn: method and change the debugger to use this message, instead of #printOn: for displaying objects in inspector panels. Here is the default implementation of Object>>debugPrintOn: aStream ^ self printOn: aStream And, as you may guess, now the proxy could choose to behave differently depending on context. P.S. Maybe i'm missing a point, and there are already the existing good practices how to get around this.. if so, then please tell me. -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] Impossible launc/use Lumiere
by nullPointer Sept. 7, 2009

Sept. 7, 2009

I try use Lumiere http://vst.ensm-douai.fr/ESUG2009Media/uploads/1/lumiereIWST-2.pdf for show a sample OpenGL window but donÂ´t works. I dont know what i doing bad.What is needed for use OpenGL in Pharo? Is a stupid idea use OpenGL under Pharo for create 2d UIs ? My idea is use Lumiere for build UIs embedded in a morphic window, but with OpenGL widgets, buttons, textboxes etc s is a possible idea? I could for example use OpenGL external widgets libs for use in Lumiere? Will be fantastic do a UIBuilder using that. If Lumiere dont works for that exists another lib o posibility?

I committed my image segment tests to the inbox (Tests-AdrianLienhard. 19). There are some initial tests in ImageSegmentTest (one fails, which documents a problem of loading symbols). I also implemented support code that allows one to analyze a segment binary (i.e., to iterate over the instances in the segment without instantiating the objects). This should simplify writing more tests. Cheers, Adrian [...] ___________________ http://www.adrian-lienhard.ch/ Great! Thanks! I'll start exploring adding more tests for this area. Sheridan

I would think a separate thread (or process) is required to handle and recover from bad pointer references. For general client/server multiplexing however, you might look at liboop for ideas: http://liboop.ofb.net/ "Liboop is a low-level event loop management library for POSIX-based operating systems. It supports the development of modular, multiplexed applications which may respond to events from several sources. It replaces the "select() loop" and allows the registration of event handlers for file and network I/O, timers and signals. Since processes use these mechanisms for almost all external communication, liboop can be used as the basis for almost any application." There are refs to other event dispatchers on the liboop web page. FYI, -KenD
