In addition to what Marcus said above I meant that when we remove isInMemory we should also remove the swapping code that is part of image segments (e.g., the class ImageSegmentRootStub and various methods in ImageSegment) because it cannot work anymore and hence is useless.

OK, so the One Click image is really important. Nevertheless, I think there should be a mean to quickly understand the distinction between VM and image, that you can have several images. (The concept of image is new for a lot of people :), and it was for me 1 year and a half ago. It takes some time to understand how to work with. Then I thought it was a revolution :D ).

Hi, last saturday I have organized a Pharo workshop in Annecy. 6 people out of 9 discovered Pharo & Smalltalk. A first point to understand for newcommers is that you need: - the VM for your platform - the Pharo image - open the image with the VM. So maybe you should put as big sized text at the top of Download page a "Quick start" section like this: Step 1: Dowload Pharo image and unzip it. Step 2: Download the VM for your platform <a href....>Mac OSX</a> <Windows><Linux> Step 3: Run the squeak/pharo binary (pharo.exe on windows, squeak.sh on Linux, ...). A file brower is opened, select the .image. Step 4: Have fun Cheers, Laurent Laffont On Sun, Mar 21, 2010 at 12:48 PM, Adrian Lienhard <adi(a)netstyle.ch> wrote: > Hi all, > > I've updated the website content, in particular the following pages, which > are linked from the welcome workspace: > > http://www.pharo-project.org/documentation/getting-started > http://www.pharo-project.org/documentation/tutorials-books > > If you have any suggestions to improve the website (e.g., for the FAQ), > please let me know! > > Cheers, > Adrian > > BTW, I also updated the download links to the new Pharo RC3 image > > ___________________ > http://www.adrian-lienhard.ch/ > > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project >

We can work out this script if necessary but, I think, it is really necessary? What about new packages or packages deleted respect to the old release? Also, the it isn't reliable, check the lines: ProfStef-LaurentLaffont.14 => ProfStef-Core-LaurentLaffont.2 Refactoring-Core-lr.101 => ProfStef-Tests-LaurentLaffont.2 Refactoring-Spelling-lr.18 => Refactoring-Core-lr.115 Refactoring-Tests-lr.31 => Refactoring-Spelling-lr.19 I think that this part should be abandoned and at least for now, no changelog released (:) is the first version there isn't anything to compare with in fact). For the 1.1 release, we'll add the changelog, respect to 1.0. So I vote for the easy solution, nuke this part. Or put a new file with the text of the workspace, because for many people, after closing the initial workspace they won't know how to open it again. So instead of a changelog, create a new README file and put that. Cheers :)

Re: [Pharo-project] Question about HostMenuSystem

by Mariano Martinez Peck

Thanks Michael. Now I have another question. In the latests PharoCore 1.1 I cannot see the VM menu. I only see the options "Squeak VM" and "Edit". But the HostMenuSystem was only removed in Pharo 1.0 with the ifPresent: in processMenuEvent: In 1.1 that method is correct. Then....I don't understand why I don't see the VM menus like Tools, Debug, etc. Should I see them ? Adrian any idea ? Maybe there is a problem with the Smalltalk startUpList ? I know it has been changed in previous updates.
