Call for Participation in the Smalltalk Devroom at FOSDEM 2014. http://www.fosdem.org, please forward " A devroom for the Pharo, Squeak, Amber, GST, EtoilÃ©, Seaside, Moose Smalltalk projects & Newspeak as derived language. Smalltalk environments offer a very high development productivity, unmatched by their successors. Come do some pair programming with us and experience yourself the advantages of a real OO environment" The meetup will take place Saturday, February 1, 2014, from 9AM until 5PM, building AW. This room has 72 seats, a VGA video projector and wireless internet. More information will be available later. If there are volunteers to record video content, the FOSDEM organization kindly offered to provide needed equipment & instructions. Please let me know if you would be willing to spend some time pointing a camera at a speaker. Proposals on content and format are welcome. People interested in running a session should send me an email at stephan ( @ ) stack ( dot ) nl with 'FOSDEM2014â in the subject and the following information: - Their name - The project they are associated with - A short bio, to be put on the website along with their speaker name - (optionally) a picture of themselves - The title of their session (which will go on the website and in the booklet) - A abstract describing the session in further detail. - The desired length of the session. - The desired time slot in which they want to hold the session. I will send out updates on a regular basis to the lists and anyone stating his interest. Suggested values for the duration are 55min, 25min, 6m40 (Pecha Kucha). The desired time slot is meant to help you prevent conflicts with other dev rooms in which you might have a talk or your travel arrangements. There are alternative, non smalltalk-specific tracks available: lightning talk and the main track The deadline for submissions is December 31, 23:00 GMT+1. Devroom related URLs: http://www.pharo-project.org http://www.squeak.org/ http://etoileos.com/ http://www.seaside.st/ http://smalltalk.gnu.org/ http://www.moosetechnology.org http://amber-lang.net http://newspeaklanguage.org/ http://www.esug.org First proposal already arrived: Stefan Marr proposed: I could give a presentation on SOM (Simple Object Machine) Smalltalk. I would especially go into detail of the Truffle-based and the RPython (PyPy) based implementations to show modern ways of language implementations with the goal of achieving high performance.

Spotlight Demo
by Sean DeNigris Jan. 10, 2014

Jan. 10, 2014

I needed an entry completion with groups, like Mac's Spotlight. While I was at it, I figured it would also be useful as a UI for the existing Spotlight. So I made a SpotlightMorph, which is a very Mac-like stand-alone Morph, which is a textField + results morph, and an adaptor for EntryCompetion, SpotlightEntryCompletion, which can be passed to #entryCompletion: A short screencast will be available at https://vimeo.com/82953583 in about 45 minutes. And here's a screenshot for the impatient ;) To load (tested in Pharo 2.0 latest): Gofer it smalltalkhubUser: 'SeanDeNigris' project: 'SeansPlayground'; package: 'Spotlight'; load. Then try: SpotlightCompletionExample open. or SpotlightMorphExample exampleFileSearch. or SpotlightMorphExample exampleSmalltalkSearch.

Unifying Testing Ideas
by Sean P. DeNigris Jan. 4, 2014

Jan. 4, 2014

We have some cool matchers (Phexample, StateSpecs), some nice mocking libraries (Mocketry, BabyMock), and Phexample's acknowledgement that tests build on each other. The problem is, it's hard to cherry-pick and build one's perfect test enviroment. For example: - Phexample and Mocketry, whose matching frameworks break each other - Phexample and BabyMock both require subclassing from their own TestCase subclass, so they can't be used together. I wonder what the solution is? Maybe some registration scheme? It'd be nice to be more coordinated here. As a first step, I manually merged BabyMock and Phexample to produce the following (IMHO) gorgeous tests... testNew self library should receive: #FMOD_System_Create:; with: FMOD_SYSTEM new; does: [ :h | h handle: 20. 0 ]. self library should receive: #FMOD_System_Init:; with: [ :a | a handle = 30 ]; answers: 0. ^ FmodSystem new. testNewSound | soundFile system | system := self given: #testNew. soundFile := FileLocator vmBinary. self library should receive: #FMOD_System_CreateSound:to:with:; with: soundFile fullName and: FMOD_SOUND new and: [ :h | h = system handle ]; answers: 0. ^ system newSoundFromFile: soundFile. testPlaySound | sound | sound := self given: #testNewSound. self library should receive: #FMOD_System:PlaySound:on:; with: sound system handle and: sound handle and: FmodChannel new; answers: 0. ^ sound play. testChannelIsPlaying | channel | channel := self given: #testPlaySound. self library should receive: #FMOD_Channel_IsPlaying:storeIn:; with: channel and: NBExternalAddress new; does: [ :c :isPlaying | isPlaying value: 1 ]. ^ channel isPlaying. The tests... let's call them specifications... clearly state how the object should talk to the FMOD library. The neat part of Phexample is that even though each specification uses the result of the last, it's smart enough not to fail the dependent if the #given: fails. It moves it into "expected failures" this is important because otherwise a failure deep in the system would make it difficult to pinpoint since there could be many failing specifications. n.b. in this case, I'm not sure that mocking is the best strategy and I may end up using a hand-written stub, but I wanted to do a case study. One area where I've really found mocks to shine is internal to one's system. That is, I'm writing an object and discover that it must talk to another as-yet-unwritten object. So I mock it out and in so doing define its API, which I then go implement. Also, the mocks are using a custom extension to BabyMock that allows you to pass the arguments do #does:, so it will not run on vanilla BabyMock ----- Cheers, Sean -- View this message in context: http://forum.world.st/Unifying-Testing-Ideas-tp4726787.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Compiling chapter of "Pharo for the Enterprise"
by Natalia Tymchuk Jan. 3, 2014

Jan. 3, 2014

Hello. Merry Christmas. I write a chapter to "Pharo for the Enterprise". And I want to compile it, but when I executing ./compile.sh DSL/DSL.pier, like it is writen here: https://github.com/SquareBracketAssociates/PharoForTheEnterprise-english/bl… , I get No yet implemented. I just start this chapter and it isn't ready to be added to the PFTE.tex. Should I add it to PFTE.tex or there are another way? What can you recomend me? Thanks. Best regards, Natalia

Thank you for Pharo
by Volkert Barr Jan. 3, 2014

Jan. 3, 2014

Thank you for Pharo â¦. I am following the development of Pharo since its fork from Squeak, and i am really impressed what you crazy guys all have archived the last years. It all evolved to really nice language, a fantastic nice looking live programming environment, cool packages and a growing ecosystems. I have so much fun using Pharo. Thank you. 2011 i gave me a push to learn Pharo and last year i decided to do a small research prototype with it. The goal is a tool to analyze and visualize application landscapes. I have implemented a small repository model for the different architecture levels, some data analytic rules on top the model, and some model visualizations. For visualization i use Roassal/Mondrian. For Data-In/-Export i use simply NeoCSV. Next year i plan to add more data analytic rules, to add model transformation operations to "simulate" landscape transformations (projects), and to use 3D visualizations with Roassal3D (City Metaphor). If all works fine, we see what 2015 brings ... Pharo is really a productivity boost for me. If you are able to play around with the objects in an interactive environment life is getting so much easier. My wishes for Pharo: - Some kind of "Pharo Capability Map". It is really hard to understand for a newbie what Pharo is all supporting, what is planed for the future, what the library names are, .... - Stable Pharo 3.0 - Roassal3D (Roassal is so coooool, one of the killer frameworks for Pharo). - More User Interface programming examples - 64 Bit VM and MultiCore Support Thank you guys, and best wishes for 2014 Volkert

Pharo3 issues
by jannik.laval Jan. 3, 2014

Jan. 3, 2014

Hi all, I am porting Phratch in Pharo 3.0 and I have some problems with the interface. I uses a one-click Pharo3.0 #30664 Here is a list of what I have: - in a debugger, it is not possible to do a Cmd-p to evaluate an expression. This appears only if I select with the mouse. If I make the selection with shift-arrow it works. It means that the selection with mouse or with shift-arrow are not the same. - In monticello browser: when I select my project, all the repositories available in Pharo are shown. As in Pharo 2.0, it should show only the concerned repositories (2 or 3 max). - In a browser, when I did a change in the source code of a method, then I select another method, the changes are lost, without asking if I want to save changes. Could one confirm that they are bugs (not new features) ? and if they are already reported. Cheers, Jannik

debugger broken?
by Alexandre Bergel Jan. 2, 2014

Jan. 2, 2014

Hi! I have faced a serious situation with the debugger today with Pharo 3.0: 1 - Open a workspace, and doit on the expression: 1 + 4. self halt 2 - Open the debugger, select with the mouse the expression 1 + 4 and press Cmd-p 3 - the debugger apparently consider the word halt as a variable. https://pharo.fogbugz.com/f/cases/12545/Debugger-broken Since I am using GTDebugger (in the Moose image), I have not seen it before...
