Re: [Pharo-users] how to see methods implemented in super classes

by stepharo

The problem is that you have to flatten inheritance so this means that we would have to prefix methods based on the classes because just putting grey does not help. Long time ago there was such browser but it was not really good so we removed it. Now put yourself in inheritance mode and you can quickly browse the superclass.

I understand that encodedImage is a ReadWriteStream. So, I use 'encodedImage contents' to get the code as string. Then I assigned the code to a variable, like that: classVariable := 'iVBORw0KGgoAAAANSUhEUgAAAmAAAAIHCAIAAAC3HdQEQUJUQQJEcEAFRVE...' But I don't know how to transform it back. I tried the following: test := ReadWriteStream on: classVariable. ImageReadWriter formFromStream: (Base64MimeConverter mimeDecodeToBytes: test). But it doesn't work. It gives me an 'Error: image format not recognized' Do you know what I am missing here ? Thank you

[Ann] System monitoring for pharo images

by Norbert Hartl

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

Re: [Pharo-users] Alt-tab between windows

by Sebastian Heidbrink

See, this is why I love Smalltalk.... Tell me a different environment where you can actually have such discussion. To make this a little clearer. Pharo and Squeak are solely open source. So one might say,.... well this can be done/extended/changed in Eclipse, too. How about VW and VAST? Well, you can change the development environment and it's behavior according to your needs, too. Want a putton to print something out for development purpose? Just add it :-D Try this with Visual Studio and xCode on that level. Avdi if you think the things you have seen so far are cool?! Well, that is just the beginning and you actually can make your environment easily even cooler,... once you have taken the first hurdles. With GlamourToolKit, Pharo community is even bringing this to a more abstract level and I love playing with it. I wish I was deeper into Pharo already. Isn't there somebody who could just hack a small .st file to file-in the desired behavior that Avdi is looking for? A temporary hack? Cheers!

Re: [Pharo-users] Alt-tab between windows

by jtuchel＠objektfabrik.de

Avdi, I mostly work in other Smalltalk environments than Pharo, like VA Smalltalk. It has native windows and so the ability to switch between windows using alt-tab is there. I must admit that there is a certain threshold in the number of open windows when this is not really helpful any more. I tend to hit that number pretty fast in a typical Smalltalk coding/debugging sessions. Things have changed in Win 7, because there I can use the window manager to close the windows right in the window switcher. That makes perfect sense if you have 15 inspectors open, none of which shows current data or instances any more. Or if one of them does, I can't decide which one ;-) So sometimes I wish for features like "close all windows of this kind" to kill all inspectors, for example. What I want to say with this that I am not really using alt-tab to switch between windows, but rather to kill a few to come down to a sensible number ;-) But I understand why you miss it. For Pharo, there is a special problem: it is its own windowing environment, so it should probably better not use the O/S' key combination to switch its windows, right?
