Help (perfect for newcomers) migrating a technical FAQ
by Mariano Martinez Peck April 9, 2011

April 9, 2011

Hi folks. I had a good idea and and it perfect for someone that wants to help and don't know how. It is not the most entertained task, but I promise you will learn a lot. Mostly, if you are newcomer. The idea is basically to migrate the FAQ that is here: http://scg.unibe.ch/wiki/faq/pharofaq to a new section in the collaborative Pharo book: http://book.pharo-project.org/ So....any takers ? Let us know so that we generate a new user in the Book The idea is also to check whether what is says is still correct for pharo or if it needs an update. Or even how to improve it (from the view of a newcomer). Thanks Mariano

WebClient
by Sven Van Caekenberghe Aug. 24, 2010

Aug. 24, 2010

Hi, Andreas Raab's 'new' WebClient/WebServer seems quite nice, as he says himself: As a result, we now have what I think is a pretty decent HTTP server and client implementation for Squeak 4.1 and hopefully we can nuke HTTPSocket sometime soon. WebClient is superior in every respect. Is this something that will / should fit seamlessly into Pharo ? Or even become preinstalled ? I didn't try his ConfigurationOfWebClient since the last version was unreadable and it seemed like an experiment, while his textual explanation was easy to follow. To load it into and to make the unit tests run in Pharo 1.0 I had to make a couple of fixes (to WebCookie#printOn: and WebServer class#serverString). Who should I sent these changes to ? But even then 1 unit test failed (#testServerDestroy). Furthermore, some the changes in his package WebClient-Pharo seem a bit dangerous, especially a modification to SocketStream#peek (and the failed test was doing a peek) and an override of String#, some others are unneccessary as far as I can see.

[Survey] Assess the cycles in your software
by Laval Jannik Aug. 24, 2010

Aug. 24, 2010

Hi Pharoers, and Smalltalkers in general, Have you seen waited to assess the cycles in your software? Now you can :) We request some of you to perform an experiment using DSM to see your software package structure and to fix cycles between packages. Our tool shows dependencies between packages and highlight some bad dependencies generating structure cycles. It also helps to understand dependencies. Your goal is to fill a survey using our tool. I prepared a mini-tutorial about DSM and eDSM. It can help you to understand the visualization tool. To ease the use of our tool, I loaded it in a PharoCore1.2. And there are two archives available: - the first contains an image with our tool with a model of Pharo loaded in it, so you can play with our tool on pharo itself. It can be downloaded here: http://dl.dropbox.com/u/7739334/dsmWithPharo.zip. Pay attention, the image is slow. - the second contains the same thing without the model of Pharo. Here, you have to load your code, then populate a moose model and use the tool. It can be downloaded here: http://dl.dropbox.com/u/7739334/dsmWithoutPharo.zip The two archives contain the tutorial and the survey. If you are a pharo integrator, we suggest you to take the one with Pharo model loaded, else the other. To use our tool, load your tool in Pharo. Then do "MoosePanel open", and import your software in Moose by "import from Smalltalk image". When it is imported, select your project in the list on the left of MoosePanel, and select "all model packages" on the list on center. Then, you have two choices: - you can scan all your project: right click on "all model packages" and do DSM. - or select "all model packages" then select some packages in the next list and right click, do DSM. After that, you can perform the survey (with reading of the tutorial). We need your answers for the end of August. So, you have two months to do it. If you have any question, just let me know. Best regards, Jannik. --- Jannik Laval PhD Student - Rmod Team - INRIA Certified Project Management Associate (IPMA) http://www.jannik-laval.eu http://rmod.lille.inria.fr ---

Rotating a String or Text Morph
by Carla F. Griggio July 31, 2010

July 31, 2010

Hi everyone! I'm trying to rotate a String or Text Morph. The way I'm doing this is evaluating: transform:= (TransformationMorph new asFlexOf: 'hola' asStringMorph) openInWorld . The string morph opens in the world and it looks OK. Now, I rotate it doing: transform angle: 80. And it rotates OK, but a black background appears and I don't know how to remove that, I can't find what's making that black background appear. Am I doing something wrong? Is there another way to rotate a string morph? Thank you! Carla

Merging
by David McCloskey July 19, 2010

July 19, 2010

I'm trying to merge code in Pharo 1.0 and I figured out how to point the arrows the right way but I can't figure out how to say that I'm done or accept my changes. There are 2 conflicts. If I right click on the message name in the top left pane, I can pick to keep current version, use incoming version, or mark as conflict. This works on a whole-message basis. But I can also click on the arrows in between the 2 versions of code and pick that I want one line from current version, one from incoming version, etc. How can I then say that I want to use the result of that to resolve the conflict? -- Dave McCloskey davemccloskey(a)gmail.com

How to make "extract method" preserve my formatting?
by Pat Maddox July 16, 2010

July 16, 2010

The extract method refactoring works great but always formats my code in a way that I hate. It indents certain things way too much, adds parens where I don't want them, etc. Is there a way for it to preserve my formatting? I wrote the code to be nice and readable to me, and I'd like to keep it that way. Pat

Evaluation of Pharo for Commercial Project
by Runar Jordahl July 14, 2010

July 14, 2010

I am looking at Pharo to evaluate whether it can be used for a mid-size commercial project. The system will use Seaside. I have looked at Pharo 1.0, 1.1 and 1.2. I am impressed by the work done so far. Pharo looks and feels a lot better than Squeak, and a lot of enhancements have been done since the project started. There are however a few issues which hold us back from using Pharo, listed (in decreasing importance) below: 1 - Package Management >From what I have seen so far, the concept of âpackages and categoriesâ is confusing. We are used to VisualAge and VisualWorks, which clearly shows the structure of packages in the browsers. In Pharo we cannot find browsers which give us the same overview. We are uncertain how packages are made and how they show up in Monticello. At one point we thought category == package, but that seems not to be correct. We note that method extensions are possible, but we also struggle to understand all aspects of them. I notice that a âPackage management systemâ is in work, so hopefully this area will improve. 2 - Dependency Management between Packages Since we are unable to organize our code in packages, controlling and verifying dependencies between them is hard. But from what I understand, there are not many tools for controlling that packages do not break dependency rules. 3 - Name Space Support I understand name spaces will not be supported any soon. We have a project with thousands of classes, and name space support would be nice to have. 4 - Break Point Support It would be better to have break points, than having to insert code like âself haltâ into the code. Is there any reason to believe Pharo will improve to meet our requirements? Did I misunderstand some aspects of Pharo, or are there tools which can solve what we see as shortcomings? Kind regards Runar Jordahl

July 10, 2010

We got a one year engineer position to support the development of a demonstratior for Moose. The ***constraints*** linked with the position are that the person should have got his master in 2009 or 2010. The starting date is 1 of December 2010. The salary should be around 3500 Euros bruto ~> 2300 Euros before taxes (but after health insurance). The job will probably consist in - getting Moose running into a web browser - having a better reporting system. - building a dashboard - porting part of codecity What this of course means is that it's kind of a cool job: work in a research lab, but no paper writing, no teaching, no administration. In addition: -> live in France (one hour from Paris, 1h20 from London, 35 min from Brussels) -> try a lot of good beers (our office is just 10km from the border to Belgium) -> enjoy french food -> code all the day in Smalltalk and a bit of C By september we should decide if we take this year in 2010 or 2011 (for decembre 2011 the person should have got a master in 2010 or 2011).
