[Pharo-project] Platform and portable versions for Pharo 2.0 too
by Esteban Lorenzano March 29, 2013

March 29, 2013

Hi, I "backported" the 3.0 publish mechanism to Pharo 2.0. I suppose the 2.0 Summer will be like this then :) http://files.pharo.org/platform/ Cheers, Esteban

[Pharo-project] Project Show & Tell - LEKtrek
by Ben Coman March 29, 2013

March 29, 2013

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

[Pharo-project] Non-Smalltalk content in Pharo and Nautilus
by Torsten Bergmann March 28, 2013

March 28, 2013

When working with Seaside (or other frameworks) one often works with non-Smalltalk resources stored within the image (CSS styles, images, ...) often stored as strings within methods: myCss ^'body { background-color: #ffffce; }' or script ^'alert("hello from Javascript");' I also often see Base64 encoded images, or when working with XML a method might return XML content. With things like Helvetia [1], the reworked autocompletion/syntax highlighting and new browsers like Nautilus in mind I wonder if (may be in the not so far future) I can: - click on a Smalltalk method to get ST styling and edit functionality - click on a CSS content method to do CSS styling and completion - click on a method with a form content to display the picture (and not the Base64 encoded string) - click on an XML content to browse the XML tree - click on an HTML providing method to edit HTML and maybe preview - click on a method with CSV to edit the tabular data within a grid - click on a primitive method to see Slang or C/C++ code - ... Internally the content can be distinguished using pragmas: myCss <mime-type: text/css> ^'body { background-color: #ffffce; }' Are there any plans to move Pharo into this "not only Smalltalk" in methods direction? Is it already possible to easily extend Nautilus with "pluggable" custom panes depending on the method content. I see that there are buttons on the Nautilus side. Wouldnt it be better to have "Tabs" with "Source" as default and where I can add my own custom tabs? Would be a lot of work to provide editors and stylers for all the mime-types or autocompletion for JavaScript, SQL, ... whatever. But the question is more "do we have the groundwork so people can built up on it." Any comments? Thx T. [1] http://scg.unibe.ch/research/helvetia

[Pharo-project] One more project for GSoc 2012
by Serge Stinckwich March 28, 2013

March 28, 2013

One more project idea for Smalltalk GSoC 2013. ---------------------------------------------------------------------- Title: Phratch, a port of Scratch to Pharo 2.0 Level: intermediate Possible mentor: Jannick Laval Possible second mentor: Serge Stinckwich Description: Phratch (https://code.google.com/p/phratch/) is an ongoing port of Scratch and BYOB on Pharo 2.0. The current prototype is still suffering from a lot of bugs. Part of the work will be to add unit tests to the existing project. Even if this is a port to Pharo, we will try to build a new version that is flavor-independent. The long term objective of Phratch is to be able to use it for teaching software engineering and robotics. Technical Details: Pharo and some knowledge of Squeak Benefits to the Student: Student will participate to a very cool project. Benefits to the Community: Scratch will be rebuild on top of a modern Smalltalk version and will benefit from lastest development in the core library and VM. ---------------------------------------------------------------------- -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://doesnotunderstand.org/

[Pharo-project] Ring & namespaces
by Ben Coman March 28, 2013

March 28, 2013

I see in a few scattered bits and pieces that Ring will support namespaces. So that presumably that will assist in porting VW code to Pharo? How near is that functionality? cheers -ben

[Pharo-project] about a new pharo site
by Esteban Lorenzano March 28, 2013

March 28, 2013

Hi, I would like to discuss something about a complete redesign of the site because right now, while it was good some years ago, now is old and confusing... I would like something clean and easy, more or less like the ruby on rails site: http://rubyonrails.org ideas? Esteban ps: this is a brainstorm for a change that will take time, do not expect too much too soon :)

[Pharo-project] in anybody out there? who uses 2.0?
by Esteban Lorenzano March 28, 2013

March 28, 2013

Hi, Here in Pharo headquarters we are shock that there are just 10 new bugs reported for 2.0 after the release... So... I wonder... is that because we made a really cool release, or just because nobody is using it? Cheers, Esteban

[Pharo-project] How to redraw only a part of a morph
by Tristan Bourgois March 28, 2013

March 28, 2013

Hi! I try to optimize the graphic framework I'm porting. I have good performance but I have some problem to reDraw the morph of my view. When I reDraw my morph I use 'invalidRect:' with the bound of the part I want to reDraw but every step my morph is entirely reDraw. Does I have to use another method? Or someone can explain me how pharo manage the repaint of morph? Thanks :) I will ask today if I can make a video of my work because is very impressive of what we can do on Pharo with the framework! And if the reDraw is functional we certainly have the same performance with Pharo! So good news :) Tristan
