Just wondering what was the status of Slots regarding "first class relations" described in "Flexible Object Layouts" - and availability of examples/tutorials. https://core.ac.uk/download/pdf/51216612.pdf cheers -ben

Pulling Web XML data into spreadsheet

Unfortunately due to IT lock down I cannot use Pharo at work, but the first 1:30 of video [1] demonstrates a nice use case to aim for DataFrame + FastTable. Similar functionality in Pharo would make a compelling video, to the degree it may even be worthwhile including this out-of-the-box to make a great "first ten minutes" experience for newcomers, or at least a one-click install from the catalog (linked from the help file). What parts do we have for putting together something like this? [1] https://www.youtube.com/watch?v=6H7tBL97orE cheers -ben

[ANN] OSSubprocess Bugfix and enhancements release
by Mariano Martinez Peck Oct. 6, 2017

Oct. 6, 2017

Dear all, I have just released a new bugfix and enhancements release v0.2.5 for OSSubprocess as you can see in [1]. This new release is thanks to the awesome work of Guillermo Polito [2]. He found a problem (and a fix) that would hung/block the Pharo image in a wait state. This problem has been forever and I have faced it myself. It would only happen when using #waitForExit and under certain scenario. Because of that, I recommend everyone to move to this release. Aside from that serious bug, he has also done quite some improvements in the tests and in the Travis setup. Once this PR [3] has been merged and SmalltalkCI updated, our Travis build [4] should show all green builds for Linux/OSX and Pharo 5.0 and 6.1. I have also copied the configuration into Pharo 5.0 and 6.0 catalog so as of tomorrow, it should be there. Cheers, [1] https://github.com/marianopeck/OSSubprocess/releases/tag/v0.2.5 [2] https://github.com/marianopeck/OSSubprocess/pull/25 [3] https://github.com/hpi-swa/smalltalkCI/pull/320 [4] https://travis-ci.org/marianopeck/OSSubprocess -- Mariano http://marianopeck.wordpress.com

Never-ending computations and cmd-dot
by HernÃ¡n Morales Durand Oct. 6, 2017

Oct. 6, 2017

Hi, Guys I have the situation you will recognize in the attached picture: A never-ending recursive computation which generate zillions of pre-debug windows when cmd-dot key is pressed. Is there any setting, or any way to put a monitor to detect that cmd-dot is creating too many windows so will pop-up just one or two? Maybe someone researched this issue, does it makes sense? Cheers, HernÃ¡n

[Ann] PharoLauncher v1.0.1 released!
by Christophe Demarey Oct. 6, 2017

Oct. 6, 2017

Hi all, I just released a new version of the PharoLauncher 1.0.1. Here are major improvements since last version: Pharo launcher is now distributed with a Pharo 60 image with a 32-bits threaded VM (to avoid hangs when using OSProcess). Add a VM management utility able to find (and download) the appropriate VM for a given image. So, the launcher is NOT shipped anymore with an extra VM. It will fetch required VM when needed. Pharo Launcher files (images, VMs) are now considered as user Documents (easier to find). Consequently, they are now stored in the standard documents folder, i.e. $HOME/Documents/Pharo on OS X, $HOME/My Documents/Pharo on windows, $HOME/Pharo on Linux (some linux distributions provide a document folder but some others not, so we put it in the HOME directory in all cases). In this folder, you will find your images and virtual machines needed to run images. Use of ProcessWrapper to run images on Windows. Adds download of sources file for Pharo images > 60. Left panel is now used for official images and Jenkins jobs templates and right panel is used for local images. New mooc entry with the image ready to start the Pharo Mooc. New deprecated category to find old official Pharo images. Use system unzip when possible (Pharo unzip does not manage file permissions nor symbolic links). You can get platform bundles from files.pharo.org: Os X: http://files.pharo.org/platform/launcher/Pharo_1.0.1.dmg Windows: http://files.pharo.org/platform/launcher/pharo_installer-1.0.1.exe Linux: http://files.pharo.org/platform/launcher/Pharo-linux-1.0.1.zip Enjoy, Christophe. For those wanted more info on how the adequate VM is computed, here is the process: determine the image format version find (and optionnaly fetch) a compatible VM (a VM able to run this image format) and run the image to get its Pharo version number find (and optionnaly fetch) the appropriate VM for this specific Pharo image version. Sources files are also downloaded with the VM when applicable. run the image with the appropriate VM

Iceberg - loading baseline
by Jan BlizniÄenko Oct. 6, 2017

Oct. 6, 2017

Hello I have a local clone of git repository and I am looking for code that adds this repository to Iceberg and then loads its baseline into Pharo. I am using Pharo 6.1 (image 60510) and last stable Windows VM. Right now I am experimenting with following code, it adds the project into Iceberg, but does not load the baseline. The code is: SystemSettingsPersistence updateSettingNodes. "sets ssh key locations" (Smalltalk at: #IceRepositoryCreator) new url: 'git@gitlab.com:bliznjan/nameofmyproject.git'; location: '/C:/Users/User/Pharo/repo/nameofmyproject/filetree' asFileReference; subdirectory: 'filetree'; createRepository. "this part seems to work fine" Metacello new baseline: 'NameOfMyProject'; repository: 'gitlocal:///C:/Users/User/Pharo/repo/nameofmyproject/filetree'; load. "this one fails with exception below" loading the baseline ends with Exception Could not resolve: BaselineOfNameOfMyProject [BaselineOfNameOfMyProject] in C:\Users\User\Pharo\images\TestingImage1\pharo-local\package-cache C:\Users\User\Pharo\repo\nameofmyproject\filetree (Libgit) Those paths seem correct - the package-cache is located in exactly that position (but does not contain anything that relates to my project) and the filetree (repository) in the mentioned path and there is a BaselineOfNameOfMyProject.package directory in there. Also, if I then try loading the baseline manually via Iceberg, by right clicking on BaselineOfNameOfMyProject in Packages tab, I get exactly same exception. Loading packages one by one manually via Iceberg Packages tab works. Also, loading the baseline via GitFileTree works.
