Only one week left!! - ESUG 2014 REMINDER: 11th Innovation Technology Awards
by jdelgado＠lsi.upc.edu Aug. 8, 2014

Aug. 8, 2014

ESUG 2014 REMINDER: 11th Innovation Technology Awards http://www.esug.org/Conferences/2014/Innovation-Technology-Awards Have you written innovative Smalltalk? The developers of any Smalltalk-based software can enter by submitting a 3-5min video of their software. Entrants demo their systems in a session at the end of Monday August 18th 2014, after which the conference attendees vote. (A vote consists in providing a sorted list of 3 preferred pieces of software.) The top 3 teams with the most innovative software will receive, respectively, 500 Euros, 300 Euros and 200 Euros. The results are announced in the Awards ceremony that is held during the social event. Applicants should provide the following information on the conference registration server. Once you have registered your personal info, an 'Awards' menu allows submitting your software. You can provide this information when you first register, or login again later and update your details. The registration server will open soon. You can start preparing your software right now though. Info to provide: Name of the software Licence information (free, shareware, or commercial) Name of the Smalltalk dialect used Name, Affiliation and Country of developers Besides, it would be great if the submission could include: URL for a video (3-5 min) showing a screencast / demo of the software URL for downloading the software or at least a runnable demo Deadline: August 15th Any Smalltalker can apply (students, companies, ...). The presented piece of code/software should be written in Smalltalk or directly support Smalltalk (e.g. Smalltalk VM). All Smalltalk dialects are accepted. The applicant should be "strongly related" to the presented code, be it as an author, as owner of the copyright/copyleft, or as an official representative of the copyright/copyleft owner. Bests, Jordi

[Remainder] Call for participation to the Second Visualization Contest with Roassal
by Alexandre Bergel Aug. 8, 2014

Aug. 8, 2014

Dear colleagues and friends, We are happy to announce the Second Visualization Contest with Roassal. What can I win? - 150 euros, sponsored by ObjectProfile - a Ã¼ber-cool ObjectProfile T-shirt and some wonderful stickers - maximum publicity of your work - a nice award certificate, delivered during ESUG How can I win? - you have to produce a visualization with Roassal. You can use the Pharo, VisualWorks, Amber or VAST version of Roassal. Here is an example of what we expect http://bit.ly/sunburstDemo http://bit.ly/GraphET https://vimeo.com/96091089 about smartbrowser https://vimeo.com/94724841 about GraphBuilder http://www.youtube.com/watch?v=uOmox7NgRAg&feature=youtu.be on AspectMaps, by Johan Fabry, the winner of the contest last year - making a video is mandatory. The video will weight the most in our decision. The video could be of any length and has to include your name and say that is was made (partly or completely) with Roassal. No need to talk, just show off! - making your code available and easy to install will help you get more points How can I submit? - send the links of your video and other material (if needed) to info(a)objectprofile.com Every email you will send to this email will be acknowledged. If you do not receive a 'Ok' from us, it means we haven't read it, in that case send your email again after a few days. - the deadline for submitting is August 11, 2014 Mini FAQ? - Is the object-profile team allowed to participate? No - I know nothing about Roassal, how can I start? Roassal comes with a large set of examples. On Pharo, just use the example browser available from the world menu. The book http://www.deepintopharo.com also contains chapter on Roassal 1 and Mondrian. You are also very welcome to ask question to the Pharo or Moose mailing lists about Roassal. Or simply send email to info(a)objectprofile.com . We will help you. - Iâve heard about Roassal2, Roassal3d, Roassal1. I feel lost in all these keywords! Wellâ¦ Roassal1 is available on VisualWorks and VAST. Roassal2 works on Pharo and Amber. Roassal2 is a major revamp of Roassal1. The documentation on Roassal1 may be easily adapted to Roassal2. - Should my visualization or code be open source? No need for this, whatever license is fine. However your video has to be public. - How can I get more information? Just comment on the facebook https://www.facebook.com/ObjectProfile or using Twitter @ObjectProfile or send email to info(a)objectprofile.com or the pharo or moose mailing list - What I submit two different videos? Yes, no problem with that. As many as you are productive. - Who won last year? Johan Fabry with AspectMaps made a nice video about visualizing aspects. - How will judge the videos? both the esug community and the object profile team. The Esug community will have 30% of the final grade, object profile the remaining 70% Cheers, The profilers

Metacello Projects: one canonical config/repo for all platforms
by Sean P. DeNigris Aug. 8, 2014

Aug. 8, 2014

There are two things that have bothered me about our use of Metacello, but I couldn't explain exactly why until now. These are two guidelines that I think are important: 1. ConfigurationOfMyProject should live at repoOfMyProject. Any MetaRepoForXyz should only be a copy of this config 2. Platform-specific config sections are not optional Without these two things, we're back in Babbel. Here's why... I wrote a configuration that depended on several well-known projects. Someone had very generously updated the configs and placed them in metaReposForXyz (e.g. http://squeaksource.com/MetacelloRepository) so that's the repo I referenced in my config. In the meantime, the same was done for later Pharo versions (MetaRepoFor30, etc). Now I'm stuck - either I have to manually manage platform variations of project dependencies myself, or settle to only ever have my config work in latest Pharo - but I'll still have to update the repo url for each new version which is a pain. Of course I understand that editing directly in a MetaRepo is very tempting (and I've done it myself), it is a quick and dirty hack that subverts much of the value of Metacello. Of course, there are limits to our ability to follow #1, like where we don't have access to the repo, but it doesn't even seem like we're trying. And there are limits to #2 like maybe we don't know how to get it to work in Squeak, but we can at least keep Pharo versions working. I have been using Mariano's workflow of using latest Pharo as the reference implementation and adding compatibility shims for previous versions. If we don't take an extra moment to do it right, we simply push this work onto users. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Metacello-Projects-one-canonical-config-repo-for-all-… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Agreed. Smalltalk-80 v2 had no literal fractions. ObjectWorks and VisualWorks have never had literal fractions. I can't speak for other dialects, but I'm fairly sure none of the Smalltalk/V, Team/V lineage had literal Fractions either.

Deprecator

Hello Pharo users, I'm pleased to announce the release of Deprecator. It's a prototype of a small tool that permits you to deprecate method by annotating them with a <deprecated: ...> pragma. This pragma takes a rewrite expression as argument that specifies how to rewrite the message send to the deprecated method. If such a deprecated method is executed, a warning is thrown and a debugger opens. This debugger has a little 'Rewrite' button that permits to rewrite the sending method according to the rewrite expression and then resume the execution with the new rewritten sending method :) The implementation is a proof-of-concept and is a bit hacky here and there, but it works. Example: You have a class C with a method that you deprecate. Its rewrite expression tells that if it's executed as the result of a message send of the form: <receiver> deprecatedMethodArg1: <arg1> arg2: <arg2>, this message send should be rewritten to: <receiver> replacementMethodArg1: <arg2> arg2: <arg1>. Note you can change the order of arguments or even the receiver. C>>deprecatedMethodArg1: o1 arg2: o2 <deprecated: '`@receiver replacementMethodArg1: `@arg2 arg2: `@arg1'> ^ #deprecated C>>replacementMethodArg1: o1 arg2: o2 ^ #replacement C>>senderMethod ^ self deprecatedMethodArg1: 1 + 1 arg2: 2 + 2. Then if you execute C new senderMethod, and then click on the "Rewrite" button of the debugger, then sending method is rewritten to: C>>senderMethod ^ self replacementMethodArg1: 2 + 2 arg2: 1 + 1. and the result is #replacement. The repo is on sSmalltalkHub: MCHttpRepository location: 'http://smalltalkhub.com/mc/CamilleTeruel/Deprecator/main' user: '' password: '' I hope for comments, feature suggestions, code reviews, contributors, etc :) BTW, if you have a better name for this project let me know! For example, I thought about Ammonite because it's an extinct animal (analogy with deprecated) and it fits the sea naming theme. Cheers, Camille
