I would suggest you load the Zinc WebSockets addon package: https://github.com/svenvc/docs/blob/master/zinc/zinc-websockets-paper.md In particular, look at ZnWebSocket class>>#to: where after an initial request/response interaction, the actual connection used in the client is taken and used to run a completely different protocol. I guess in your case you would then keep on reading responses. But it might be simpler than that, if the server returns an actual infinite response, you could ask for ZnClient>>#streaming: true and use the resulting ZnStreamingResponse's contents (a stream) to keep on reading. Good luck and let me know how it goes, I am pretty sure we can get this working ! If you can tell me how I can access such a response with my twitter account, I can try as well. Sven

Hi, Somehow I got myself into giving a 30min âcoffee breakâ talk here at the lab. Pharo: A Reflective System http://www.slideshare.net/MarcusDenker/pharo-a-reflective-system http://marcusdenker.de/talks/14Inria30MinScience/PharoAReflectiveSystem.pdf Nothing new, of courseâ¦ but it was not that easy to do a 30minute talk about that, I have to say.

Thank you for > your effort. Seconded. If the English is at this level all the way through I, as a native English speaker, won't have any complaints. It's great to have some documentation done and it's much appreciated. TW

[OT] A Little Smalltalk, SmallWorld, SmallWorld 2007, Athena... and now Gossip

by Sergi Reyner

Hello everyone! This is a bit off-topic but I thought it may interest some of you! A few weeks ago I got interested in making simple 'clicky' games that could be played on Android, mostly for my daughter. After looking around, I found LibGDX for Java, which runs on Windows, Mac, Linux, Android, iOS, web... Of course, at one point I got fed up with Java and decided to look for a tiny Smalltalk that I could embed inside my game, to save me the trouble of writing Java code. And I found the software mentioned in the topic. Most of you have probably heard of at least the first one. Long story short, I mixed SmallWorld, SmallWorld 2007 and Athena, fixed a couple of bugs, hacked enough support it to allow me to rewrite in Smalltalk the demo game I had written in Java, added some classes and convenience methods, and finally found what I consider to be a cool name for all of it: Gossip :) Here are some links: http://web.engr.oregonstate.edu/~budd/SmallWorld/ReadMe.html http://bergel.eu/athena/?Athena http://russell-allen.com/computing/smallworld/ https://github.com/raydeejay/gossip https://github.com/raydeejay/gossip/wiki https://github.com/raydeejay/escape-game Feel free to yell at me or whatever :D Cheers, Sergi

Re: [Pharo-users] [gsoc-mentors] GSoC: call for ideas

by tesonep＠gmail.com

Project idea Description: Enhance refactorings with type information Skill level: Advance Possible Mentors: Guillermo Polito / Esteban Lorenzano / Santiago Bragagnolo Name of the Student: Pablo Tesone Keywords: tools, refactoring, code completion, type inference. Description: During the development of a program in any programming language, the IDE has a very important role. It will never replace the knowledge of the programmer but it can make his life easier. As Smalltalk doesnât have explicit type information, the IDE can not perform the same mechanisms that are present in IDE like Eclipse or Intellij IDEA. These mechanisms can be very useful. The idea of this project is to add type inference mechanisms to try to provide more information to the refactoring and code completion tools. It is important to say that the idea is not to check types or correct the program, but to allow the programmer to have more information.

I think its great that Spec has finally documentation, it makes it far easier for me to use Spec and evaluate its usefulness. Thank you for your effort.

by Usman Bhatti

[Anne Etien could not post this msg on the mentors list I m forwarding it on her behalf]. Title: FAST JavaScript model Level: advanced Possible mentor: Anne Etien Possible second mentor: Nicolas Anquetil or Yuriy Tymchuk Description: For in depth source code analysis a support of abstract syntax trees is required. FAST is an abstract syntax tree extension for FAMIX meta-model that is used by Moose technology. The goal of this project is to create a JavaScript version of FAST. Technical Details: As programming languages are different, their AST representations are different too. FAST model aims for creation of as generic as possible core that can be extended for different languages. Also the structure of a model allows creation of generic algorithms like symbol resolution, metrics calculation and rule checking that will work for any language. Prototypes of FAST for Smalltalk and Java are already implemented. During the project a student will implement the JavaScript model. More detailed information about FAST is provided in the Moose day presentation: http://youtu.be/dRr3WHOD3x4 Benefits to the Student: The student will gain a deep understanding of a JavaScript syntax and abstract syntax tree model. He will also learn about PetitParser framework, and gain knowledge about software modeling and analysis. Benefits to the Community: Community will get a FAST model for JavaScript that can be used for software assessment with Moose. Also this model can be used later in PhD projects such as automation of source code translation. With this third model, the community will have raw material to real think and improve generic algorithms based on AST.

Re: [Pharo-users] [ANN] Spec documentation in PFTE book finished

by Johan Fabry

Ben and I focused on getting a readable text out there that is useful for people wanting to use Spec. Personally, having experience with writing lots of English, I'm actually quite happy with how it turned out and I think the text is quite readable. This being said, we are nonnative English speakers (and writers) and I am sure that there are worse sentences than this one in the text. I don't think this one is bad at all, actually. If a decision is made by the people coordinating the PFTE book to appoint an editor, I'm sure Ben and I will be happy to cooperate.
