[Pharo-project] Incompatibility between Pharo and Seasidehosting
by Damien Cassou March 20, 2009

March 20, 2009

Hi, there is a problem with Pharo on Seasidehosting. Using a stock Pharo image 10225, installing Seaside from Universe, it works perfectly fine locally. As soon as I upload and run the image on Seasidehosting, it doesn't work anymore.(503: Service Temporarily Unavailable). There is nothing in the log files accessible through the seasidehosting admin interface. You can see the problem on http://diagen.seasidehosting.st. To reproduce: - download Pharo version 10225 (newer versions have the annoying MIME problem) - ScriptLoader new installingUniverse - In the Universe browser, install Seaside. - Upload the image and the changes file to a seasidehosting account - Start the image Since all Pier images are now based on Pharo, this is a problem for all new pier users. -- Damien Cassou http://damiencassou.seasidehosting.st

[Pharo-project] Drawing graphics with OB
by Alexandre Bergel March 20, 2009

March 20, 2009

Hi David and others, Each OBNode understand the message definition. In the first version of OB, this definition method is supposed to return an instance of OBDefinition or one of its subclass. I saw a way to have a graphical object instead of the text pane. What is the trick to achieve this? Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

A further question on OB. How can I change the font of a list. Having bold or italic menu entries for example. Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

[Pharo-project] SqNumberParser!
by GÃ¶ran Krampe March 20, 2009

March 20, 2009

Howdy folks! In working on Tirade I stumbled upon SqNumberParser and its history: http://bugs.squeak.org/view.php?id=3512 ...it was added to the image in 3.9 but not hooked into Scanner - Scanned still uses Number class>>readFrom:. Now... In Tirade I can use whichever - but using SqNumberParser makes it more correct, and quite faster - although "less portable" since I would depend on it. I will now make Tirade use SqNumberParser *if present* in the image, otherwise fall back on Number class>>readFrom:. This opens up some slight potential incompatibility issues, but whatever. Question: Is there anything stopping 3.9+ including Pharo to start using SqNumberParser from Scanner>>xDigit? And oh, the class name is not so good IMHO, why the Sq prefix? And yeah, class var not used in SqNumberParser: BelllerophonBase10 :) regards, GÃ¶ran

[Pharo-project] Composing UI layout question
by astares＠gmx.de March 19, 2009

March 19, 2009

>parent width & height (or any other parent coordinate) depends on >its submorph's fixed width/height. Ahh, should have read your mail more carefully. You are not only interested in a flexible alignment within the parent - but also to depend on own child bounds/parameters. The new JavaFX provides something like this by using the "bind" keyword. See http://weblogs.java.net/blog/aim/archive/2009/01/layout_primer_f.html in section "Using Binding to Layout Nodes" Bye T. -- Psssst! Schon vom neuen GMX MultiMessenger gehÃ¶rt?

Wouldn't it be possible to use the version history to make an algorithm which figures out who's *mostly* responsible though? ;) Cheers, Henry ----- Opprinnelig melding ----- Fra: Michael Rueger <m.rueger(a)acm.org> Sendt: 19. mars 2009 17:19 Til: Pharo-project(a)lists.gforge.inria.fr Emne: Re: [Pharo-project] just for fun... extensibility of Morphic StÃ©phane Ducasse wrote: > lol > I'm not that we want to know. > Some of us could cry to see their idols falling from their statute :) Well, it would also be unfair for those having done maintenance as their initials would be on the method.

[Pharo-project] System-Settings
by Alain Plantec March 19, 2009

March 19, 2009

Hi all, here is a new version: - taken into account Adrian remarks - made all part of the Setting-Settings package. - added filtering: by token or by package - added style: a style is represented by a subclass of SettingStyle with a method #load - one can manage user defined style (no need for demo mode, only have to create a style named 'my beautiful demo mode') creating a style consists in creating a subclass of SettingStyle with a class method #styleName and with an instance method #load. Style export and import relies on simple fileout/filein. - the pragma keyword is now a parameter: the default is <setting> as in: desktopColor <setting> ^ DesktopColor ifNil: [DesktopColor := (SettingManager newSetting: 'Desktop color') parent: #desktopColorSettingNode; default: (MessageSend receiver: Color selector: #green)] all standard settings are browsed by 'SettingTree new open' An application or a particular part of the system can use its own keyword. as an example <menu> as in: aSettingAboutMenu <menu> ^ ..... all menu settings would be browsed by 'SettingTree forKeywords: #(#menu) open' I've attached the package System-Settings, SettingSandBox1, SettingSandBox2 for testing and a UserDefinedSettings with a style example. Cheers Alain
