Re: [Pharo-project] Mars, stuck on callbacks (again)... need opinions

by Schwab,Wilhelm K

Esteban, FW(very little)IW, my first reaction as I started reading was "has he thought about native boost or alien?" Callbacks have been in a possible-but-not-supported state for a long time. I believe Eliot recently mentioned callbacks in FFI, so it seems to be an idea that is solidifying. At present, I have .so that exports functions in lieu of callbacks. I have to recompile the library to change anything :( but it's number crunching so I get C speed for my trouble :) The functions are used small numbers of times, so Smalltalk speed and flexibility would be preferable for all of my uses to date ~:0 Good hunting!

[Pharo-project] New features ...

by James Ladd

Hi All, >From what I understand of Smalltalk new language constructs can be added as long as they fit in with the "message passing" scheme/principle. Since the release of Smalltalk-80 I think some new constructs have been added and I need an example for a piece I am writing. Can someone tell me what syntactical construct was added since Blue Book - Smalltalk-80 ? I think "on:do:" was, but Im not sure. Rgs, James.

+1 Good Christmas to you and your family. About: do you think that a good open-source ERP in Smalltalk would help you? I'm interesting to ERP in Smalltalk. I think it with: - Seaside interface - Gemstone OODB ( GLASS ) - Magritte for meta data base description Ciao, Dario

[Pharo-project] Mars, stuck on callbacks (again)... need opinions

by Esteban Lorenzano

Hi guys, I'm doing some "advance callbacks" for Mars, and I'm having several problems with table renderers (they are called A LOT of times and needs to be efficient). The ObjectiveCBridge is not as efficient as that calls needs to be executed, and well... I was planing to spend some time on this, trying to see how can I improve the callback velocity. And then a question came to my mind: do I spend time improving current ObjectiveCBridge implementation... or I better use Alien and migrate everything to it? some context: 1) it was always planned to "sonner or latter" migrate the ObjectiveCBridge stuff to alien (there is another . 2) Alien is not working -yet- for iPhone. It is planned (bah... it is "thought") to run Alien in iPhoneVM too. 3) Alien callback implementation is a lot cleaner than the current ObjectiveCBridge implementation (which relies on both sides semaphores, when alien callbacks relies on "image ownership") So... it will delay a little a release of Mars? sure it will... but in the long way it will be better. I would like to hear your opinions, cheers, Esteban
