The NB part is really advanved stuff currently under development. Just download the One-Click for Pharo 1.4 and you'll get the fast Cog (i.e. JIT) VM for free. Now, and this can be very confusing for beginners, Pharo Smalltalk is not the same thing as Squeak, it is evolving much faster, possibly at the cost of backward compatibility. Running older code on top of Pharo will not always work and possibly raise Deprecation warnings. In particular, etoys or scratch won't just work, even just discussing everything involved is above beginner level. That being said, hundreds of externals packages do just work. What is it that want to do ? Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

Hallo Igor, Hmm, I do not understand totally ;-( NBCog does not complain but the image it has loaded about something which is 'Deprecated'? Yes, probably, the used image complains about it? If so, where could I download a 'good/starter/' image for NBCog? Or where and how could I read to build an image of my own? (mingw32 available and cmake on Vista)...

Basicaly it is a Cog VM + NativeBoost plugin. The "faster" part comes from Cog , which has JIT.

Re: [Pharo-users] Welcome to newcomers

Hallo, nice, that you recognize newbies as me ;-) Several questions I have: I have meanwhile Pharo 1.4 (squeak, etoys, scratch) and NBCog on my PC and an image which runs with squeak from http://www.preeminent.org/squeak/tut2007/html/ NBCog show too the Pharo-tower, question is it really Pharo? As a friend says NBCog is several times 'faster' then ..., reason for trying NBCog (too). Question, in NBCog, importing the Laser-Game code I get messages like Deprecated: Form subclass: #FormStub instanceVariableNames: 'locator' classVariableNames: '' poolDictionaries: '' category: 'Graphics-Display Objects''Deprecated14' What should "Graphics-Display Objects" be, where is it replaced?

there is the finder in the tools menu. When you know the code of Flaps you do not want to have them :) Stef On Sep 26, 2012, at 6:17 PM, Peter K.H.

Re: [Pharo-users] modal dialog

by StÃ©phane Ducasse

Florent We are not happy of the current design. UIManager allows us to control window request in headless mode. Now this is not really satisfactory. Facades are often bad smells to me. There is UITheme and othersâ¦ and the responsibilities are unclear. Now you do not have to subclass you can extend it. Still I'm not happy about the overall design. For example, some logic of the debugger building should be located in the Debugger class and not in UIManager or whatever class. This is why we are working on Spec and its UIBuilder and we want to rewrite all the tools. But it takes time. We will get there after 20 is out probably. Stef > Thank you, it works well !

Welcome to newcomers

by StÃ©phane Ducasse

Hi guys Since there are regularly new comers, here is a little ad-hoc welcome message :). First: Welcome! welcome and welcome Second: our goal is to create an ecosystem around pharo: if you need material to teach, if you have idea or needs for business or anything else just let us know. Our goal is to be able to reinvent our system and at the same time make sure that we can all create wealth at all levels. Third: we are working hard to get our vision: a nice, little and powerful reflective system. If you want to understand what we are doing please read the document Pharo vision on http://www.pharo-project.org/community/consortium You will understand our current effort. Four: you can get an impact on Pharo :) There are a lot of different ways to contribute. - feedback - bugs idea for enhancements see http://code.google.com/p/pharo/issues/list - book participation (we are working on deep into pharo http://rmod.lille.inria.fr/pbe2/ - translation - adding comments - building great stuff - using packagesâ¦. So welcome. Stef PS: Pharo is not the end, Pharo is the mean to create a powerful clean, lean system with a great community.
