I do not know because I do not foresee the use well. Gofer for: #Pharo1.0. Gofer project load: 'FFI' looks simple to me. Then if I want to load a specific version Gofer project defaultVersionFor: 'FFI' '1.2' Gofer project load: 'FFI' version: '1.1' if I need the one before 1.2 if it makes sense.

Ok...but how can I do the following: there is a setting that in Core has XXX value and I want to change it for the Dev image. Creating whole Style doesn't make sense as I only want to change one setting. In addition, happens what you told me in this mail, and finally it is difficult to manage I think: imagine today I create a Style and tomorrow you create ore settings...do I need to update my style to contemplate such setting ? Actually, I want to change two things: FastDragging (to true) and "Show update option in World menu" (to false). So, how can I do that ?

Re: [Pharo-project] Single threaded Pharo IDE?

by Schwab,Wilhelm K

Sig, If you give us "overlapped calls," we'll make a statue of you. I'll bring the chissels :) On sockets, I'm not terribly worried about the blocking part: what I don't want is for the whole image to go under because of mis-typed URL or something. In short, I'm worried about too much blocking, not the absense of it.

Given that i have a full control, what happens with NativeBoost, i could create a native thread to serve for handling such 'overlapped' calls, and at image side, it will just put a process, which made a call into a waitable state, while other processes could still continue to run. > Bill > > ________________________________ > From: pharo-project-bounces(a)lists.gforge.inria.fr > [mailto:pharo-project-bounces@lists.gforge.inria.fr] On Behalf Of > Andrei Stebakov > Sent: Monday, May 10, 2010 5:31 PM > To: Pharo-project(a)lists.gforge.inria.fr > Cc: Adrian Lienhard > Subject: Re: [Pharo-project] Single threaded Pharo IDE? > > > > 2010/5/10 Mariano Martinez Peck <marianopeck(a)gmail.com> >> >> >> 2010/5/10 Andrei Stebakov <lispercat(a)gmail.com> >>> >>> >>> I just started to use Pharo 1.0.
