[Pharo-project] [Pharo Project] Installer / Installer Monticello
by Norberto Manzanos March 11, 2010

March 11, 2010

I found some bugs in Installer and InstallerMonticello packages. Is this the properly forum to report them? If not, sorry for bother you. InstallerMonticello >>mcDetectFileBlock: The detection is made with #beginsWith:, but if you have two different packages which begins with the same string, it would detect a wrong package. Reeplaced by #copyUpToLast: $- InstallerMonticello >>mcSortFileBlock If the file has no number (it could happen, yes, and it happened to me with a file create by MonticelloConfiguration, which I didn't remember it existed) the files collection is sorted wrongly, since #asInteger will answer nil. Replaced #asInteger by #asNumber I made other modifications, but I'm not sure they are part of the developing plan of the package. Errors are logued only with an output on the Transcript, so it's very difficult to separate errors form manu other messages shown there. I add a #logErr: method which adds the string to a new instance variable in. I attached the package.

[Pharo-project] ESUG GSoC english speakers help needed!!!
by Mariano Martinez Peck March 11, 2010

March 11, 2010

Hi folks. Neither me or Janko (GSoC admins) have English as native language. Thus, there are probably some mistakes in the application text for the GSoC. The link is http://gsoc2010.esug.org/application.html If you can review them and send them to me by mail I would really appreciate it. Thanks in advance. Mariano

[Pharo-project] Google Summer Of Code 2010 news!!!
by Mariano Martinez Peck March 10, 2010

March 10, 2010

Hi smalltalkers. I have been asked to be the admin of GSoC 2010. The backup or second admin is Janko MivÅ¡ek. As you may know, Squeak has participated in GSoC 2007, 2008 but failed (not accepted) in 2009. We are not sure if we will succeed this year but we will try to do as much as possible. We think that one of the most important reasons why we failed in 2009 is that Google was looking for bigger communities that Squeak. This is why this year we all go under the ESUG umbrella. We present ESUG as the mentor organization and we cover ALL open-source Smalltalk dialects, not only Squeak. Pharo, Smalltalk/X, GNU Smalltalk, Cuis..they are all invited to participate. Also cross platform projects like Seaside, AidaWeb, Magma, etc are welcome. <forThoseWhoDoesntKnowWhatGSoCIs> It is a Google program that support (money) students to work on different open-source projects. Google doesn't talk or manage directly to the students but trough "Mentoring Organisations". Those organizations have to apply to GSoC. They have to give a lot of information, included a list of ideas/projects. Each project has a description and a mentor. Then the students apply for each project. If the organization gets selected by Google they will tell you how many "slots" they give. Suppose they give 5 but we have 20 projects....then we vote and the most voted projects win. The student has to do the project and the mentor has to help and guide him. The mentor receives 500 USD and the student 4500USD. For more information read: http://code.google.com/soc/ </forThoseWhoDoesntKnowWhatGSoCIs> The most important thing is the deadlines we have. We started late so we are very near to the first deadline which is 12/03/2010 (less than one week). For that deadline we need to submit all the information of the mentor organization (answering several questions) and give the list of ideas/projects and the mentors of that. We have created a webpage (Thanks Janko!!) where we will put all the information. We will make this page public soon (we still need to review a couple of things). But for the moment we would REALLY appreciate if tell us your ideas. To do this, just answer to this email. Then we will collect the information and put in the website. For each idea you need: a short title and a paragraph (for the moment) explaining the idea. After, we need that the people that are willing to be mentors start to apply as mentors...please, consider yourself being mentor. Sometimes it is not that difficult. I mean, don't be shy as sometimes being helpful, being aware of the dates, answering emails, etc is more important than the Smalltalk knoweldege. We can have a lot of ideas, but we need also mentors for that. We even would need a "substitute" for each mentor... Just as an example you can see the ideas of the previous years: 2007: http://wiki.squeak.org/squeak/5936 2008: http://wiki.squeak.org/squeak/6031 2009: http://wiki.squeak.org/squeak/6120 That's all for the moment. Cheers Mariano

Ok, I'm a bit behind in my email but I would help mentor if need be. Just to ensure it works ok on os-x and also to ensure support for objective-c creeps in there somehow since Apple's direction is towards everything in Objective-C frameworks versus "C" library calls.

[Pharo-project] Paint gradients rectangles on #onDraw: method
by nullPointer March 10, 2010

March 10, 2010

Well, IÂ´m continue working on a Grid widget. My old grid was very slow in load data. I changed the old mechanism of columns and rows ( each row was a panel with cells in tableLayout ) by #onDraw: mechanism, painting the cells and contents of it. Now is incredible much more faster. I believe than another people with more knowledge could do more fast too. Now my next problem is implement the "styles" of widget. I need paint gradient rectangles, for color of rows , alternate rows, cells etc. Is possible do that with #onDraw: mechanism? exists some previous example? Many thanks for the answer; regards. -- View this message in context: http://n4.nabble.com/Paint-gradients-rectangles-on-onDraw-method-tp1587597p… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

11255 ----- - added tests for the compiler to test shadowing of self, super, thisContext, true, false and nil. Thanks guys - we know you :) - Issue 2086: Introduce a cleanUp/cleanUp: protocol from squeak / keith idea! MyClass class>>cleanUp: aggressive This (class-side) method is called with an argument that indicates whether to do aggressive, i.e., potentially destructive cleanup. Doing aggressive cleanup will delete projects, change sets, uni-classes and more. Gentle cleanup is expected to only flush transient caches. If your class only has gentle cleanup you can simply implement MyClass class>>cleanUp By default #cleanUp: delegates to this method (similar to startUp/startUp: and shutDown/shutDown:). You can run cleanup by executing: Smalltalk cleanUp. Smalltalk cleanUp: true. Thanks luc for your analysis. After lunch in hot room is never that good for my brain :) Stef
