[Pharo-project] odd bug in Squeak 4.3, also in Pharo 1.3?...
by Lawson English March 2, 2012

March 2, 2012

I was creating a new video tutorial to show how to find all comments in all classes but I'm getting errors in both Squeak 4.3 and Pharo 1.3. In Squeak 4.3, the error is: Key not found: Comment In Pharo 1.3, the error is: Improper store into indexable object. the code is: myNav := SystemNavigation default. (myNav allMethodsWithSourceString: '"' matchCase: false) do: [:each| Transcript show: each asString, ' => ', ( each actualClass commentsIn: each sourceString);cr ] In Pharo, the error shows up after the Transcript output: UndefinedObject>>DoIt (myNav is Undeclared) In Squeak the error shows up each time after the Transcript output: [...] AbstractSound class updateScorePlayers => an OrderedCollection('Force all ScorePlayers to update their instrument list from the sound library. This may done after loading, unloading, or replacing a sound to make all ScorePlayers feel the change.') UndefinedObject>>DoIt (myNav is Undeclared) UndefinedObject>>DoIt (myNav is Undeclared) Help? Error shows up in Squeak 4.3 image running both in the all-in-one distribution, and running on Cog VM. In Pharo 1.3 using Cog VM. Mac OS X 10.6.8. Thanks, Lawson

[Pharo-project] [Announce] S8 in the Concrete Jungle
by Elvio Fernandez March 1, 2012

March 1, 2012

Hi! Alejandro Reimondo (Ale) will make a presentation about S8 platform and U8 service on Tuesday March 6, 2012 to NYC Smallltalk Developerâs group. http://www.nycsmalltalk.org/2012/01/10/s8-release-candidate-smalltalk-on-js/ There is a lot of topics to talk about..., the topic of most interest (to us) is to explain what we are doing with S8. A breaf description of our regional point of view about OT and Smalltalk, and our proposal of a modern formulation of development using Smalltalk will be the starting point of the presentation. The S8 platform was implemented to let us(smalltalkers) be responsible of our execution environments (as it was in the early days of smalltalk). That impose a change of attitude and the formulation/idea must be supported by tools and evidence/experience of others in the same field. As a demostration on how we can do that with S8, Ale will mention the platforms we have implemented for using the U8 service (designed to make worldwide social development with smalltalk http://u8.smalltalking.net ). On technical side, to mention where a person can start application development and self-learning using U8, he will describe the frameworks we have implemented on top of S8 (we all know the importance of frameworks) and the process we are using for development/testing of frameworks. The presentation is also open to the topics of interest of the audience. And Ale will be happy to respond questions about how to use S8 in diferent contexts of development. Some of the technical points that will be of interest are: - how to use our FFI framework? (make API calls, use native libraries and implement callbacks using S8; 100% smalltalk code) - how to do server side development? (NodeJS framework) - how to use your code from other smalltalks? - how to use javascript libraries? and (more important) how to write interfaces to existing libraries fast and minimize errors / testing points? - how to develop for Android and phones? - how to use cloud services? - how to work using U8? How to contact experts and people to do development of frameworks using the U8 service? - why we minimized the toolset at this stage? and what powerfull features of smalltalk we support today. - what is not implemented yet? and how to contribute? - ... In all the presentations and coding events we made here (in Buenos Aires) the time has been short for going deep in groups, and the presentation was important to get in touch with people that has interest in global development as it is used to be in this decade. So, if you are near NY on March,6 join us. If you can't attend there next week, please contact us at info(a)smalltalking.net and consider we have open the Betatesting site to start contributing and using U8 from now and we are doing one betaworks meeting per week to let people put their hands on the frameworks, tools and S8 platform, in small groups. ...If you canÂ´t wait and want to start coding now/today, please visit the U8 page ( http://u8.smalltalking.net ) and register there to become a member of our community, to be in contact with people and companies interested in social development using Smalltalk. cheers, --------------- on behalf of Smalltalking Associationwww.smalltalking.net

Re: [Pharo-project] Nautilus version 4.0.4

Example: Multi-selection, lots more - Specs, declaratively define UIs. - RPackage: Merge SystemCategories with PackageInfo, for real. - Ring. This replaces MethodReferences and provides a meta-model for code. I think in the end it's a question of philsophy. Some people say that a project like Nautilus should run on 1.3 and 1.4 (and possibly Squeak and even VW and VA), and never ever improve anything in the systems We disagree ;-) Marcus -- Marcus Denker -- http://marcusdenker.de

[Pharo-project] Small usability glitch
by Sebastian Sastre March 1, 2012

March 1, 2012

Hey guys, when opening a SystemBrowser and executing a "Find class..." command (with context menu or cmd-f with focus in the packages pane) there is a dialog listing the classes that matches whatever you type. So far so great. The problem is that time and again I use the arrows keys to select the one that I was looking for and press enter only to get a dialog closed in a no-op. Note that: 1. to make that dialog work, the only way is to use the mouse to click on OK or double click the target class and 2. the input even says: "Hit return to accept" so.. sebastian o/

We really need to think hard about Monticello... just look at 1.4 from https://ci.lille.inria.fr/pharo/job/Pharo%201.4/lastSuccessfulBuild/artifac… Image size: 17.7MB Hmm... that's large. Pharo is growing out of leaps and bounds! We add crap all the time! No, actually not. 1. Monticello ancestry. MCVersionInfo allInstances do: [ :each | each instVarNamed: 'ancestors' put: nil ]. doit, save. --> 12.7 MB. So MC wastes 5MB for history. Now history is important. But can we actually use the history? The Changes and Source are together now 53MB... because we need the history. But, isn't that what MC should do? Why can't it do it? Even though it wastes 5MB constantly? Continuing... 2) Scriptloader. Big piece of crap. Delete the class. Save ---> 10.3 MB What it does is to define which exact package versions made up a pharo version. So we know what 14345 was *exactly*. And it records the comment of what changed. Again: Shoudn't a "software versioning and a revision control system" do *exactly* that? No? 3) "ScriptLoader new cleanUpForProduction" does 1 and 2 and removed the tests, does some cleanup --> 8.3 MB And that is with all the fonts! Fully usable. All tools. (but not SUnit). 8.3 MB.... So I really wonder if we don't need to do something different.... Marcus -- Marcus Denker -- http://marcusdenker.de

Hi guys we are thinking that we want to (rewrite) remove the support for native mac menus because it goes against the flow of things and the cleanup of the events we are doing. So before removing them we would like to assess if we should really support that or not now. Stef
