[Pharo-project] Athens work in progress: couple screenshots
by Igor Stasenko Nov. 22, 2011

Nov. 22, 2011

Stephane, asked me to show this :) Nothing fancy there, just a same window, rendered with different scale. The code which doing this, is following: testWindowRender | surf | surf := AthensBalloonSurface new form: (Form extent: Display extent depth: 32). surf drawDuring: [ :canvas | canvas pathTransform scaleBy: 0.5. " or 2 " canvas fullDrawMorph: self testWindow. ]. Display getCanvas translucentImage: surf form at: 0@0 There are problems of course: - i have to use different Paragraph class, and therefore i have to use different TextMorph subclass, because otherwise it will use hardcoded Paragraph class. The paragraph model is a bit messy. It doesn't clear to me, what role it has. I thinking that it is a cached state for Text, to draw it on screen. But apparently it is more than a cache , and there are couple things which simply don't fit with it. I am thinking about doing some overhaul with TextMorph/Paragraph later, to clean up unused stuff (believe me there's a lot of it), and to make clear separation of roles. In fact, this stuff could live by itself. You can render text without using paragraph(s) mess. But i want to integrate that with Morphic, so we can switch to Athens at some point. That's why i need to deal with this. :) -- Best regards, Igor Stasenko.

[Pharo-project] Startup Preferences
by Benjamin Nov. 22, 2011

Nov. 22, 2011

Hi guys, I did a little project which allow you to save a st script on your HDD in a preference folder (~/.pharo#{version} for unix based machine, not yet defined for windows) and run it each time an image is open. You can also decide for each item if you want it to be run each time or only once. I use it to set my author name, change the fonts, set some settings, add my password in some repo etc The code is here: Gofer new squeaksource: 'StartupPreferences'; package: 'StartupPreferences'; load. You can have a look at StartupLoader class>>#example and StartupLoader class>>#example2 If you have comments or ideas (by example, what is the path for preferences on windows ? ^^), you're welcome :) Ben

[Pharo-project] Planned downtime December 6 for seaside.gemstone.com, seaside.gemstone.com/ss (GemSource), ss3.gemstone.com (SqueakSource3) and book.pharo-project.org
by Dale Henrichs Nov. 22, 2011

Nov. 22, 2011

On December 6th maintenance will be performed on the internet link for the following services hosted by VMware: seaside.gemstone.com (GemSource) ss3.gemstone.com (SqueakSource3) book.pharo-project.org (Pharo the Collaboractive book) The maintenance window is between 1am and 5am PST with a scheduled 30 minutes of hard downtime. The services themselves will not be affected as it is only the internet link that is undergoing maintenance. The date and times are subject to change, but I thought I'd broadcast a heads up as soon as I got the information. Dale

[Pharo-project] Fwd: [squeak-dev] OmniBrowser and ToolBuilder
by Lukas Renggli Nov. 21, 2011

Nov. 21, 2011

FYI: The mail of Colin Putney to the Squeak mailing list regarding the future of OmniBrowser. For Pharo there are also some changes upcoming: The latest GUI takes better advantage of the standard Polymorph widgets and brings resizable column and faster updates. Lukas ---------- Forwarded message ---------- From: Colin Putney <colin(a)wiresong.com> Date: 20 November 2011 09:56 Subject: [squeak-dev] OmniBrowser and ToolBuilder To: Squeak-Dev <squeak-dev(a)lists.squeakfoundation.org> Hi folks, Lately I've been working with Lukas Renggli on a new version of OmniBrowser. The main focus has been on cleaning up and isolating platform dependencies so that we can have a single version that works well on both Squeak and Pharo, while fitting comfortably into each platform's idioms. That part of it has been quite well. For proper integration with Squeak, I've been trying to get OB building its interface using ToolBuilder. It *mostly* works, but there are some areas where ToolBuilder doesn't provide the functionality that OmniBrowser needs. I had planned to extend ToolBuilder a bit with the additional functionality that OB needs, but that turns out to be more work than I anticipated, and I wasn't able to get it done before the 4.3 feature freeze. So, given the constraint of working with the Squeak 4.3 feature set, I'm not quite sure how to proceed. Here are some of the options: 1) Abandon ToolBuilder and just deal with Morphic directly. This is what OB has historically done, and I'd just be updating the old Morphic code to fit better into modern Squeak conventions. There's no longer any need to have this code work on Pharo, since Lukas is now using a separate Polymorph-specific widget package on Pharo. 2) Use ToolBuilder where possible, but customize its output. This misses the point of ToolBuilder, since it means OB won't be able to work with MVC, but at least it reduces the chance that OB will get left behind if someone adds a feature to ToolBuilder. It is a bit of "worst of both worlds" situation. 3) Use ToolBuilder, and just accept that not all the features of OB will be available until they get added to ToolBuilder. I'm not sure how much graceful degradation I can acheive, but it might not be too bad, and it'll give us (me) motivation to improve ToolBuilder for Squeak 4.4. 4) Have the OB installation process patch the base image to add the needed functionality. That would be the cleanest in terms of the OB code, but has the potential to break other packages that users might want to load. I'd really like to make this next release a solid toolset for Squeak, and fix a lot of the little annoyances that cause Squeakers to avoid it. Lukas' refactoring stuff is really excellent, better than the VisualWorks refactoring browser IMHO, and I want to make it palatable to more people in the Squeak community. I'm leaning towards option #1, because I suspect it's the mostly likely to achieve that, but I thought I'd put it out there and ask the community for advice. So, how important is ToolBuilder? What options am I missing? Cheers, Colin -- Lukas Renggli www.lukas-renggli.ch

[Pharo-project] Moving a file
by Sean P. DeNigris Nov. 21, 2011

Nov. 21, 2011

Neither the Squeak file system support, nor FS seem to contain logic to move a file, like Unix's mv command. This seems like a basic piece of functionality. Why is it missing? Thanks.

[Pharo-project] scripting a package backup
by jannik.laval Nov. 21, 2011

Nov. 21, 2011

Hi Pharoers, I would like to backup my packages in a repository with a script. I have one constraint: I need to use Monticello (eg, not gofer or metacello). And I do not want to have a version incrementation. Does someone have any script or any way to do that ? Cheers, Jannik

Hi Am I right that the argument to #ifCurtailed: is run in a different process (like #ensure: in an exception case)? Cheers Philippe
