Store a png in a class variable
by Leonardo Silva May 17, 2015

May 17, 2015

Hi, I load a PNG file using the code below: pngPath := '/Users/Somefolder/UI-Theme.png' asFileReference. forms := pngPath readStreamDo: [ :in | (PNGReadWriter on: in) nextImage ]. ... But I don't want to create this dependency with a file path. I would like to be able to encode the image into a string and store it in a class variable. This way, every time I need the image, I decode the class variable back to an image and use it. Something like that, I think. Is it possible to do it? Do you have an example? Thank you!! Leonardo

[Ann] System monitoring for pharo images
by Norbert Hartl May 17, 2015

May 17, 2015

Finally I've found some time to release some of my code I've been using the last years. It is a project around system monitoring. It defines system parameters to watch and integrates them with popular tools like munin, monit and nagios/icinga/... As an example the following picture shows the monitoring of the vm memory over a day. System monitoring is basically about monitoring system parameters in order to send alerts when thresholds are exceeded or to plot graphs that enables one to estimate further progression of image behaviour. The code is here http://smalltalkhub.com/#!/~NorbertHartl/Monitoring <http://smalltalkhub.com/#!/~NorbertHartl/Monitoring> and an introduction article (more will follow) to it is here http://norbert.hartl.name/blog/2015/05/16/system-monitoring-for-pharo-image… <http://norbert.hartl.name/blog/2015/05/16/system-monitoring-for-pharo-image…> Feedback is welcomed! Hopy you enjoy it. And bug me if you have questions or something is not working. Norbert

Enhancing ICal library
by Julien Delplanque May 16, 2015

May 16, 2015

Hi everyone, I took a little time to enhance the ICal library and to make it work with Pharo 4! So I forked the one on smalltalkhub (http://smalltalkhub.com/#!/~pdebruic/iCal) and put all the modified code on github https://github.com/juliendelplanque/pharo-ical. Why did I forked? Well, I wanted to make it work on pharo 4 first, so I contacted the owner of the smalltalkhub repository. He wanted to keep it working on other smalltalk than Pharo. The problem was that the lib used Url class that were deprecated in Pharo 3 and even removed on Pharo 4! So I managed to repair the package using ZnUrl. Since I don't know if the owner of this lib on Smalltalkhub have time to manage the problem to keep the lib "multi-smalltalk", I have chosen to fork it so he can keep his version compatible. Good news are that I plan to keep it alive as long as I can, write some documentation for it when I have time and even try to enhance it. I already added a GTInspector extension to have better representation of iCalendar when inspecting them in Pharo. The version on master branch is supported by Pharo 2-3-4 (didn't check with Pharo 1). Regards, Julien

Testing a seaside task and component?
by Alexandre Bergel May 15, 2015

May 15, 2015

Hi! I have a rather simple question regarding seaside. Assuming I have a method MyTask>>go How can I test it in a unit test? Executing MyTask new go leads to the error: 'You can only #call: and #answer: from within a callback or a Task.' Pity the Seaside distribution does not have the Sushi example and some tests.
