[Pharo-project] ImageSegment part 3 ready to integrate
by Mariano Martinez Peck Feb. 8, 2010

Feb. 8, 2010

Issue http://code.google.com/p/pharo/issues/detail?id=1940 SLICE-Issue1940-ImageSegmentCleaningPart3-Mariano.3 in PharoInbox. - remove #fixCapitalizationOfSymbols - remove TTCFontSet code from #comeFullyUpOnReload: This even fixes a cycle dependency between ImageSegment and Multilingual - the following implementors were moved to category *System-Object Storage: *startUpFrom: *saveImageSegments: *areThereImageSegments *rootStubInImageSegment: *scanFromNoCompile: aStream forSegment: anImageSegment Now we have a cleaner kernel (Object, Behavior, etc) and a little step more to put ImageSegment as a separate package. This is not possible yet as there are method from the kernel referencing to ImageSegment. Take into account that ImageSegment tests are failing but due to issue http://code.google.com/p/pharo/issues/detail?id=1941 However, "rollbacking" that problem I make sure that this ImageSegment version is working. Cheers Mariano

[Pharo-project] ProfStefBrowser, a GUI for ProfStef
by Danny Chan Feb. 8, 2010

Feb. 8, 2010

Hi! Some of you know, that I made my first dabblings in the Smalltalk world in the last weeks by writing a GUI for ProfStef. The result so far can now be found in the ProfStef repository. There is no Metacello configuration, because I don't know how to make one. Load ProfStef-Core-DannyChan.8 and ProfStefBrowser-DannyChan.18 and start with 'ProfStefBrowser go'. I've implemented some navigation buttons and some buttons to edit the tutorial in the browser. The idea is that people can annotate the tutorials on the fly and may even be able to submit their changes as improvement requests directly from the browser. It would be nice to have some buttons to remove tutorials and lessons as well, but I don't know how to remove classes and methods programmatically. And of course the GUI could have a better look. Have fun, Danny

Henrik, Ahhh, comments ... when I get a comment compiler, I will write comments along with the code... With that said, you are correct that there are missing comments and writing comments _is_ on my todo list. If anyone is interested in taking a crack at writing comments for Metacello (before I get to it), then I would be willing to read and correct them.

[Pharo-project] Metacello - the missing information??

For any given cofiguration, how does one know which version to load? There are incantations in the beginner workspace, but what happens for things not listed there? Bill

Bill, I think that loader is aimed at the consumer side of things ... it looks to be aimed at being the Gofer of Metacello ... so easy scripting is the target. In my mind there are 3 areas where Metacello has need for immediate support: browsing scripting searching Doru's Metaceller is aimed at browsing and does give one a good picture of what is going on with an existing image. Metaceller is under development but can be taken for a spin (http://groups.google.com/group/metacello/browse_frm/thread/335b8177a7b82b5e…) Esteban Lorenzano is working on Loader which is aimed at scripting Metacello tasks. Esteban is still working on Loader, so it's not quite ready for use. Searching is a subject that has only been talked about (see http://groups.google.com/group/metacello/browse_frm/thread/92c3a31178ae4a12…) With 60 configurations and counting we'll soon need better searching tools.

[Pharo-project] Latest Polymorph
by GARY CHAMBERS Feb. 7, 2010

Feb. 7, 2010

There is a new version of Polymorph on SqueakSource (Polymorph-Widgets-gvc.103) that supports a background morph for the world that resizes with the main window. I guess the backgroundSketch/Form stuff can be removed (I reused the backgroundMorph inst var - no direct way of setting did remain, accessors now). This can be used for background images (as requested): E.g. World backgroundMorph: ((UITheme builder newAlphaImage: (ImageReadWriter formFromFileNamed: 'Watery 2.jpg') help: nil) autoSize: false; layout: #scaled; lock) (AlphaImageMorph supports a few layout positions/tiling/scaling, more could be added like aspect-maintaining scaling etc.) Or could be helpful for deployed applications... set the background morph to your main UI morph, for instance.

[Pharo-project] Where to get SIXX?
by John Thornborrow Feb. 7, 2010

Feb. 7, 2010

Hi, I've looked/Googled for SIXX (and YAXO) packages, but can't find anywhere. I've found XML-Support, but not sure if this is the same as YAXO? The Sixx mcz in Pharo squeaksource is empty (should it be?) as I assume it is only extensions. I am using Pharo 1.0 RC2. Many thanks, John.
