Is Pharo the best system to make this application?
by Justin Northrop Sept. 28, 2015

Sept. 28, 2015

I've described it here: https://www.reddit.com/r/smalltalk/comments/3mk0pe/what_system_should_i_use… Basically, it's a visual programming language, and an environment controlled by this language that allows real-time shared editing of the visual language, and real-time transmission of audio and video. - Justin

is " #^ " legal syntax?
by Udo Schneider Sept. 28, 2015

Sept. 28, 2015

All, I just hit a case where I needed to return the caret character "^" as a Symbol. However simply doing something like method ^ #^. doesn't work. Even inspecting the symbol itself #^ inspect. doesn't work. "Quoting" the caret works fine: method ^ #'^'. So I'm wondering whether #^ (w/o) quoting is considered to be legal syntax and it's a parser "bug" or whether it's invalid by definition CU, Udo

[ OT ] About Encodings and Character Sets
by Sven Van Caekenberghe Sept. 28, 2015

Sept. 28, 2015

This is a nice article: What Every Programmer Absolutely, Positively Needs to Know About Encodings and Character Sets to Work With Text http://kunststube.net/encoding/ Which refers to this well known article: The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) http://www.joelonsoftware.com/articles/Unicode.html Sven PS: in Pharo, the first part of this draft might help too: Character Encoding and Resource Meta Description http://stfx.eu/EnterprisePharo/Zinc-Encoding-Meta/ A newer version will be part of the upcoming book.

[ANN] Mathex release 0.2
by Julien Delplanque Sept. 27, 2015

Sept. 27, 2015

Hi all, I just released Mathex 0.2 (https://github.com/juliendelplanque/mathex/releases/tag/0.2) Here are the improvements: - Made preview in GT-Inspector asynchronous. - Improved LaTeX code generated for compilation. - Mathex Rewriter is now loadable using 'MLoader loadRewriter'. - Removed greek letters globals, replaced them by #symbol asMathex. - Added some tests. - Some more refactoring. Documentation on Mathex-Rewriter package will be available soon on the wiki. In a nutshell it allows to write 'Mathex smalltalk' ie using literals without having to send explicitly #asMathex messages on them. So: ($b asMathex negated pm: #Delta asMathex sqrt) // (2 asMathex ,, $a asMathex) can be wrote: ($b negated pm: #Delta sqrt) // (2 ,, $a) to generate: '\frac{- b \pm\sqrt{\Delta}}{ 2 a }' if you use Mathex-Rewriter. It comes with a GUI (see attachment) that allows to write both Smalltalk and "Mathex-Smalltalk". Regards, Julien

Some news from the growing pharo teacher front
by stepharo Sept. 26, 2015

Sept. 26, 2015

Hi guys I want to let you that there will be a new pharo lecture in YaoundÃ©. I presented Pharo during a seminar and the previous minister of education was there and asked us to do a lecture in June. We did it with Damien C. by skype. And now there is an official lecture at YaoundÃ© given by Prof. Metalagia. This is an excellent news. In Togo my first visit was quite successful: 120 participants to the conferences I gave (it was still vacation time there). There were 60 students following lectures from 8h to 17h during 4 days... Yes I'm exhausted. A new Pharo lecture will start in north Togo. I will go back in December. One of the idea is to help students to get good in Pharo and build web app and other. There is a competition AppTogo. People are learning C# and others. I hope that some students will com

Hi guys I want to let you know that there will be a new pharo lecture in YaoundÃ©. I presented Pharo during a seminar and the previous minister of education was there and asked us to do a lecture.

Yes I'm exhausted ;) A new Pharo lecture will start in north Togo. I will go back in December. One of the idea is to help students to get good in Pharo and pharo web stack and build web apps and other. I hope that we can have within 2/3 year startups there. The gouverment in really pushing in that direction. There is a competition AppTogo. People are learning C# and other languages. So nothing is that easy :). I hope that some students will compete with Pharo so I will be looking for potential mentors to help them. Because I will be busy working on the mooc and other actions. Giving them advices, pointing them to the right solution/framework and may be a bit of pair programming if skype works. I distributed the Pharo Starter Kit (we will announce it officially now that I have 10 gb space on my server) People loved the Youtube videos folder I'm collecting. Yes internet is a pain there and avoiding to crawl on a slow internet is a plus. In addition the videos shows that our community is doing crazy stuff. Chloupis I put your great youtube tutorial! Thanks for it. some students watched it. Stef

Problem Loading Roassal 2 development in Pharo 4
by Johan Fabry Sept. 25, 2015

Sept. 25, 2015

Hi all, I cannot load Roassal2 development in Pharo 4, itâs missing the GTExampleFinder class (full message below). I can proceed through and still get a reasonably working version though (I guess without some examples, have not tried it as I donât need them) Would it be possible to fix the development version so that it loads in Pharo 4? This package depends on the following classes: GTExampleFinder You must resolve these dependencies before you will be able to load these definitions: RTExampleFinder gtExampleInstance class:selector:method:to: newExample ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD and RyCh labs - Computer Science Department (DCC) - University of Chile

Here I show manipulating columns and searching from a card to senders, implementors, methods of the class and class methods. https://vimeo.com/140423783 Needs GT-Spotter >= 325, i.e. at the moment the Moose 6 CI build.

Learning GT - Glamorous Toolkit
by Jimmie Houchin Sept. 25, 2015

Sept. 25, 2015

Hello, I have watched most all of the videos about GT. I am interested in learning how to use the Glamorous Toolkit. I am failing to find a beginning place for learning how to use and program GT. I am probably overlooking it some where. I have downloaded the gtoolkit.image to begin learning. I am currently browsing code to learn what I can from there. Any advise on documentation or best way to proceed in learning GT greatly appreciated. Thanks. Jimmie
