[Pharo-project] Project Show & Tell - LEKtrek

by Ben Coman

LEKtrek is "a software development platform for electrical power applications". This is my masters project to provide the GUI for modeling electrical power networks, into which researchers can plug calculations. These video presentations are still a work in progress, but just in case you needed some filler for the Show Us Your Project sessions at PharoConf/MooseDay, please feel free to use any portion of the three videos listed below. These can be viewed using VLC. Note that the 020 video was the first I ever produced and suffers a little for quality until I can fix it after writing up my dissertation. Quality gets better in the later videos 010 and 030. http://files.openinworld.com/LEKtrek/ * LEKtrek 010 Introduction 2013-02-25.mp4 - 6min - background context for the project * LEKtrek 020 Explorer User 2013-02-28.mp4 - 8min30 - a tool to explore the IEC 61970 Common Information Model (of electrical power networks) * LEKtrek 030 Modeller User 2013-03-19.mp4 - 9min - a tool for modeling an electrical power network, and executing calculations on that model. The project is based on top of Roassal, Glamour & Magritte 3. It will released open-source, but I am still musing over the finer points of several licenses, which waits on completion of my dissertation. Any and all feedback on contents and aesthetics are welcome. cheers -ben

Re: [Pharo-project] about a new pharo site

by Esteban A. Maringolo

The Vagrant site is cool. The RoR is nice too, but a little old these days. But I agree the Pharo site needs to be better, and modern. You don't have to leave the Smalltalk community to find a simple site: Amber-lang.net It has all, what I think, a newcomer would expect: an intro, a few FAQs, a code snippet, links to download it or to its Github repo. The same goes for the Node.js webiste. Python and Django on the other hand have more complex websites. Regards! Esteban A.

Re: [Pharo-project] [Pharo-users] More GSoC ideas wanted, 3 days left ....

by Andrei Vasile Chis

A short idea for a GSoC project to improve the debugger. Cheers, Andrei ----------------------------------------------------------------------------------------------------------- Title: Improving the inspection of expressions in the debugger Level: beginner/intermediate Possible mentor: Andrei Chis Possible second mentor: Nicolas Passerini, Tudor Girba Description: The debugger is a central tool in any programming language, as it helps developers understand the dynamic behaviour of applications. Furthermore, in Smalltalk, it can also be used to write code and thus extend applications while they are running. One important aspect that is missing in the current Pharo debugger, is the ability to view the value of intermediate expressions involved in method calls. For example consider the call: ^ self doSomething: (anArray at: 2) with: aStream next onlyIf: aCondition isValid. In order to view the values of the expressions (anArray at: 2), (aStream next) and (aCondition isValid) we have to directly go into the actual method call. Furthermore, viewing the return value can be more difficult, if we do not store it into a variable. The goal of this project is to add support for exploring these kind of expressions by using dedicated widgets. For example, one alternative might be adding pseudo variables into inspectors, while another might consist in using popups that display these values for any expression selected in the editor. Technical Details: The student will have to understand how the debugger works, and will have to familiarise himself with the new debugging infrastructure. Also, he'll have to look into at least a framework for building UIs (Spec/Glamour). Benefits to the Student: He will get a deep understanding of how debugging is done, on how the debugger works and he'll also interact with a framework for building UIs. Benefits to the Community: The community will bet a better debugger, in which values passed and returned by methods could be easily explored using different widgets. ----------------------------------------------------------------------------------------------------------- On Tue, Mar 26, 2013 at 12:36 PM, Janko MivÅ¡ek <janko.mivsek(a)eranova.si> wrote: > Dear Pharoers, > > Ideas are slowly coming, 14 so far, but this is way below the 30+ in > previous years.

I guess that will work out of the box under linux. I think the URL parsing with the directory letter under windows is broken. And I bet there is no test catching that either. Did you try the following? 'file://d:/' asUrl 'file:d:/' asUrl

[Pharo-project] obtaining a FileUrl through String>>asUrl

by Tudor Girba

Hi, I am trying to get to a FileUrl via the polymorphic asUrl call, but it seems I am doing something wrong. I do: 'file:d:\' asUrl but the problem seems that $: and $\ are mangled, because when I print, I get: file:///d%3A%5C Furthermore: 'file:d:\' asUrl asFileReference exists ==> false but, at the same time: 'd:\' asFileReference exists ==> true Can anyone tell me where is the mistake? Btw, the reason I am looking for this is that I would like to use the ZeroConf support to load a configuration from a directory Monticello repository and to do that I have to pass a url to the command line.
