Hello all I was looking for the XMLWriter package because it seems it is not part of the complete XML package but I am not sure which is the newest one since I have found several here : http://www.squeaksource.com/XMLWriter/ I am using pharo 2.0 just in case this is relevant. Any help is appreciated. Thanks Mohammad

New win32 VM available (was: More than 500MB for windows)
by Igor Stasenko July 16, 2013

July 16, 2013

So, after spending unproportionally huge time (2days) dealing with jenkins config idiosyncrasies, it finally managed to build it. http://files.pharo.org/vm/pharo/win/latest.zip This VM should react properly on AddressSpaceLimit=<number of MBytes> setting in .ini file. The ini file is located in same directory as VM executable. If it doesn't exists, you can run VM once and it will create it automatically. Thanks for patience. -- Best regards, Igor Stasenko.

Question about dynamic spec
by Andrei Vasile Chis July 14, 2013

July 14, 2013

Hi, I've implemented a small UI using the dynamic features of spec and I'd like to know if there isn't a better way to do it. My use case is simple: I have a normal ComposableModel that has two models - a list and a DynamicComposableModel. The DynamicComposableModel should contain a list of buttons that should change every time the user selects an element in the list. I've implemented a demo that can be seen if you download the package DynamicSpec-Examples from http://www.smalltalkhub.com/mc/AndreiChis/Playground/main and execute the code from the class comment of DSChangingButtons. My problem is that the widget containing the buttons has to define a spec layout on the class side. I haven't found a way to tell the spec layout to add a widget and use a method on the object for constructing the layout. I've manage to get away by dynamically reconstructing the layout when the selection changes, however it's not that nice because I had to duplicate the layout of the main widget both on the class side and the object side. It would be nice to add a widget to the layout like this: 'aSpec dynamicAdd: modelGetter withSpec: aSymbol ' that would call aSymbol on the object and not on the class. This may or may not make sense :) To be concrete, the method DSToolbarModel>>updateButtons will call the method dynamicLayout on it's parent which in turn will call dynamicLayoutWithSpec: on the toolbar. I'd like to avoid this, and when specifying the layout of the parent widget to call a method on the instance side of it subwidgets to get their layout. Now I'll end here this rather long email :) Cheers, Andrei

Phexample state keeping
by Norbert Hartl July 12, 2013

July 12, 2013

I'm playing with Phexampe because I think that in my current project the setup of test scenarios will be a huge part of the testing. So do it in a structured way reducing doubled initialization procedures should be something good. I'm just wondering how the state is kept between dependent test cases. A Phexample test case returns a value so that value := self given: #shouldHaveCollectedSomeState transfers the state from the dependent test case into the current. What do you do if the state produced is more complex than a single value? To be honest I don't understand why in a test case that calls #given: a tearDown/setUp cycle is executed between the first and the second test case. I think while using #given: I make the second test case explicitly dependent on the first. Why should I reset state collected by the first before executing the second? I'm a bit reluctant to create new classes for all collected state scenarios so that I can return them properly from one test case to another. Any ideas? thanks, Norbert

More than 500MB for windows
by Usman Bhatti July 10, 2013

July 10, 2013

[I know there were some discussions on the topic and the topic of 64-bit VM but I'm not sure where we stand today]. I would like to know if we can allocate more than 500MB for pharo virtual machine in Windows? I am getting an "Out Of memory" msg and the following VM statistics when trying to parse a large application with Moose. Increasing the size would be the cheapest option (in terms of effort) before trying other optimizations. tx [image: Inline image 1]

[Voyage] #selectOne: and #selectMany: with a block as the argument
by Bernat Romagosa July 9, 2013

July 9, 2013

Hi! I realize probably only Esteban will be able to answer, but I prefer to write to the list so the mail is logged and other people can benefit from it. I'm trying to use blocks as arguments for #*selectOne:* and #*selectMany:*, but it doesn't seem to work. Here's my code: MyClass selectOne: { #name -> 'Some name' } asDictionary. MyClass selectOne: [ :each | each name = 'Some name' ]. The first one works, but the second one raises a *VOMongoConnectionError*. Also: MyClass selectMany: { #name -> 'Some name' } asDictionary. MyClass selectMany: [ :each | each name = 'Some name' ]. The first does work, the second one doesn't, which prevents me from writing more useful stuff like: MyClass selectMany: [ :each | each name first = $P ]. Any idea why this could be failing? I've the latest stable version loaded via: Gofer it url: 'http://smalltalkhub.com/mc/estebanlm/Voyage/main'; package: 'ConfigurationOfVoyageMongo'; load. (Smalltalk at: #ConfigurationOfVoyageMongo) load. Thanks! :) Bernat. -- Bernat Romagosa.

[ANN] Pharo Launcher
by Damien Cassou July 9, 2013

July 9, 2013

Dear list, Erwan and I are proud to announce the first release of the Pharo Launcher, a cross-platform application that - lets you manage your Pharo images (launch, rename, copy and delete); - lets you download image templates (i.e., zip archives) from many different sources (Jenkins, files.pharo.org, and your local cache); - lets you create new images from any template. A screenshot is attached to this email. The idea behind the Pharo Launcher is that you should be able to access it very rapidly from your OS application launcher. As a result, launching any image is never more than 3 clicks away. Download: https://ci.inria.fr/pharo-contribution/job/PharoLauncher/PHARO=30,VERSION=b… Please report bugs on the 'Launcher' project at https://pharo.fogbugz.org You can contribute to this project. All classes and most methods are commented. There are unit tests. Please contribute! Source code: http://www.smalltalkhub.com/#!/~Pharo/PharoLauncher CI: https://ci.inria.fr/pharo-contribution/job/PharoLauncher Things you can do to improve the system: - check if a template is already downloaded before downloading it - add a preference mechanism (for, e.g., quit after launch, definition of your own template groups, location of downloaded templates and images) - put the launcher in the Pharo Ubuntu package so that the launcher becomes a registered appliation of the system (https://launchpad.net/~pharo/+archive/stable) - make sure the pharo launcher does not load your personal scripts (like fonts and MC configuration) - add a toolbar to enhance the discoverability of the features (currently everything is in contextual menus) - make sure rename and copy actions propose default values - make sure no debugger pops up when a user press cancels or enter an invalid name - propose multiple kinds of sorting (last used, most frequently used, alphabetically on the name) - give some information about each template (build date, pharo version) -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

Enforcing uniqueness constraints in Voyage-Mongo
by raphonic July 9, 2013

July 9, 2013

Hi, I would like to know how to set certain instance variables of my models to be unique and also if there is a mechanism to set other constraints(like presence of an embedded object) in Voyage-Mongo. I searched the MongoDB docs and it says that constraints should be implemented at the application level. Does Voyage have any support for setting constraints? -- View this message in context: http://forum.world.st/Enforcing-uniqueness-constraints-in-Voyage-Mongo-tp46… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

July 8, 2013

Hello, I am currently working with a dataset in CSV format and am trying to load it in to Moose for visualizations with Mondrian. Now, I am facing an issue with NeoCSV. I loaded the Configuration in Moose without trouble. Now, when loading my file, I do get a MNU with SmallInteger codepoint Is this a Moose issue or a NeoCSV issue ? I've tried to comment out the codepoint message to see where this was going but to no avail. Clues? TIA Phil [image: Inline image 2][image: Inline image 1]

documentation for refactoring tools in Pharo 2
by Paul DeBruicker July 5, 2013

July 5, 2013

Is there any documentation on the changes between 1.4 and 2 for the refactoring tools? Or how to use them effectively to refactor code? I'm familiar with Lukas Renggli's writing on them and used them regularly in 1.4. I'm just trying to use the RBParseTreeRewriter from within a workspace but with it limited to a package or class heirarchy. Thanks Paul

Regex question
by jannik.laval July 5, 2013

July 5, 2013

Hi guys, Just a simple question about regex: 'a' matchesRegex: '.' --> true 'aa' matchesRegex: '.' --> false As '.' represents any character, the two previous lines are ok. Now, if I test with a cr, it returns true: String cr matchesRegex: '.' --> true. Is it the expected behavior ? Cheers, Jannik

We need you for a software integration survey (reminder)
by Martin Dias July 5, 2013

July 5, 2013

Hi all, Some time ago we sent an email to ask you contributing to a research to improve tools for software integration. If you maintain a project with multiple contributors, we will greatly appreciate your participation. Your answers will be used for research purposes and to support the development of new tools. You can later access the results of this study, make free use of our tools to support the integration of changes, and maybe receive a gift. We found out that the survey was not properly working on Safari (and may be also some other browsers). And we have now corrected this issue. Up to now, we received 36 full answers and 166 incomplete answers. So we decided to give you an extra month, if you started to fill the survey, please consider resuming filling the survey. For this you only need to go back to the same site: https://sondages.inria.fr/index.php/667625/lang-en If you did not yet fill in the survey, please consider doing it now. Best regards, Martin Dias, Nicolas Anquetil, Veronica Isabel Uquillas, StÃ©phane Ducasse and the RMOD Inria team

Pharo on Fedora 19
by Daniel Miranda July 5, 2013

July 5, 2013

Hello, I tried to set up Pharo 2.0 on Fedora 19 x86-64, and for that I needed the 32-bit libraries. Using ldd I could figure out most of them: glibc (obviously), X11, OpenGL libs, ALSA, libSM, libICE. All the bundled executables/libs are okay according to ldd. But when I start pharo I get a blank screen with no response of any kind. Only Ctrl-C still works. Breaking into a debugger seems to show me the VM is stuck in an infinite loop in findMethodWithPrimitiveFromContextUpToContext() function. Am I missing a library? Has anyone had success with Pharo on Fedora yet? Thanks, Daniel
