[Pharo-project] Some questions and request for Athens
by Tristan Bourgois March 25, 2013

March 25, 2013

Hi! I have some questions and request for Athens :) 1 Do exist a possibility in Athens to draw a Surface on a Surface? This is an example of what I search: aSurf drawSurface: anOtherSurface at: aPosition (I need it for draw image on a surface) 2 About my first question, I try to draw a png image on a Surface and I get some strange behavior. When nothing is applied on my first surface and draw the image in a rectangle path I crash the VM! This an example I tried and crash my VM: |surf pharoLogo ref path patternPaint| surf := AthensCairoSurface extent: 600@600. ref := 'pharo.png' asFileReference. pharoLogo := AthensCairoSurface createFromFile: ref fullName ifFailed:[nil]. surf drawDuring: [:can| surf clear. patternPaint := can setPaint: pharoLogo. patternPaint setExtend: #None. can drawShape: (0@0 extent: pharoLogo extent). ]. Display getCanvas drawImage: surf asForm at: 0@0. If you need more information about the crash and my environment ask it :) 3. Do exist something in Athens to create some text and get the extent of the text? I tried to draw text but I only succeed to draw a text without font (only width) and I don't found how to get the extent of this text :( This is really important for the next of the porting because I'm blocking on that and the textModel is not necessary for the next of my work because they already have a layoutManager for the text. Thanks :) Tristan PS: The porting advance as well :) I have animation and that's really amazing :)

[Pharo-project] [ANN] Phratch: Scratch on Pharo2.0
by jannik.laval March 25, 2013

March 25, 2013

Hi Pharoers, I am porting Scratch and BYOB on Pharo 2.0. The name of the project is Phratch. To begin, I took Scat (a port of Scratch on Pharo1.3) and modify it to make it work on Pharo 2.0. For that I integrated FileSystem. Then, I took BYOB and port it in the project. I have some bugs, but the main features are working. The main issue is that it is slow. I will investigate that too. The goal for me is to use it for teaching software engineering and robotics. I hope to use Phratch and Pharo 2.0 to create new features. The project is on SmalltalkHub, and a google code page is available, mainly for reporting issues: https://code.google.com/p/phratch/ To download Phratch, just run this code: Gofer it url: 'http://smalltalkhub.com/mc/JLaval/Phratch/main'; package: 'ConfigurationOfPhratch'; load. (Smalltalk at: #ConfigurationOfPhratch) loadBleedingEdge. Cheers, Jannik

[Pharo-project] Smalltalkhub non-mcz files
by Ben Coman March 25, 2013

March 25, 2013

Does Smalltalkhub allow non-mcz files into the repository - for example for file based data required for Tests and examples? Or what is the preferred way of versioning test data and example data along with the source code? cheers -ben

[Pharo-project] extra class category added in Pharo-2.0 for Monticello package
by Yanni Chiu March 25, 2013

March 25, 2013

When I load a Monticello package that was developed in Pharo-1.X, into a Pharo-2.0 image, I get an extra category created. For example, a package named "Some-Thing-author.n.mcz" originally contained class categories: Some-Thing-Model Some-Thing-View In the Pharo-2.0 system browser, I see an extra category, like: Some-Thing Some-Thing-Model Some-Thing-View I thought it was just an artifact of the new browser. However, when I do a diff, before saving the changes to a Monticello version, I see that the "Some-Thing" is flagged as diff. Will this extra class category cause any trouble, if I want to load the new Monticello version into a Pharo-1.4 image?

[Pharo-project] Password reset/reminder for SmalltalkHub
by Esteban A. Maringolo March 25, 2013

March 25, 2013

As usual, I forgot my SmalltalkHub password. At the third attempt, I entered the right one. However, before that I was about to click on a "forgot password?" or similar option. But I couldn't find it. Is there a way to reset it or email it back to me? Regards Esteban A. Maringolo

[Pharo-project] Loading webdoc
by Guillermo Polito March 24, 2013

March 24, 2013

Hi Camillo! I was trying to load webdoc but there are a lot of not loading dependencies (Seaside, grease, Omnibrowser...)... The configuration does not load for 1.4 nor for 2.0... I was using this snippets: for 2.0 Gofer new url: 'http://smalltalkhub.com/mc/dh83/webdoc/main'; configurationOf: 'WebDoc'; loadDevelopment. for 1.4 Gofer new url: 'http://smalltalkhub.com/mc/dh83/webdoc/main'; package: 'ConfigurationOfWebDoc'; load. ConfigurationOfWebDoc loadDevelopment. Any hint? How did you bypass them in a safe way? tx, Guille
