Re: [Pharo-dev] [Vm-dev] Re: Random forest in Pharo

by Robert Withers

Yes, exactly. I do realize I was consciously changing that effort synchronization order. I was doing so with the idea in mind that I and others might dig into working on the VM, for threading support, while Eliot maintains focus on 64-bits...a tall order, I know. I was barely familiar with the VM, slang, interpreter, it years ago... I'm totally unfamiliar with cog. I believe another item on that list ought to be modernizing slang. So many big items!

review needed : step through package list by package first character (Nautilus package pane)

by Nicolai Hess

see issue 15184 Systembrowser package navigation inconsistent behavior I think this change would be a good addition. It makes it easier to find a package resp. navigate by typing the key for the package name first character. please try it out and give feedback.

Hi niolai I do not know and too busy to get concentrated on that or on anything in fact. After january I hope it will get better.

Re: [Pharo-dev] RPackage design documentation

by Thierry Goubier

Hi Esteban, just be carefull if you start to play with it. Endless loops, code loss and other nasty issues may happen when RPackage (overall) is desynchronized from the state of the system. The concept is simple, but the time needed to get it right was very significant. It was redesigned once already. At the same time, any time and knowledge you may gain about the RPackage internals will be very valuable for the Pharo community.

I was assuming the second scenario. Iâm saying *the syntax* will not change. That means, if you want to call memcpy, syntax will still be: #(void *memcpy ( void* dest, void *src)) what can (and will) change is the method invoking itâ¦ ffiCall:module: vs. ffiAsyncCall:callback:module: Esteban > > Robert > >> >> Esteban >> >>> >>>> - to what degree will NB syntax need to be extended to support threaded callouts. >>> >>> as described, I suppose.
