About validation
by StÃ©phane Ducasse March 11, 2018

March 11, 2018

Hi I read the chapter on validation of the mentoring course book of andres valloud. http://www.lulu.com/fr/fr/shop/andres-valloud/a-mentoring-course-on-smallta… And I love this extension of SUnit. I loved the idea when I saw it for the first time at Lugano (presentation of Leandro Caniglia). I encourage everybody to read it. Now does anybody implemented in Pharo the SUnit extension? I would like to play with it and eventually write a chapter on it for the next book. The idea is so good. Stef

Mongo lost references - bug?
by Sabine KnÃ¶fel Aug. 17, 2015

Aug. 17, 2015

Hi Esteban, I found a problem in mongo/voyage and I have reduced and extracted it for repro. I ask for your opinion if this is a bug. If you file in the code below, the method >>testDemo creates a simple model: Paper has 1:1 reference to Planet. Paper has 1:1 reference to Star. Star has 1:N reference to Planet. Star has 1:1 reference to Paper. Planet has 1:1 reference to Paper. If you run >>testDemo, you see that the model which was created is ok with all its references. (self assert: thePaper planet = thePaper star planets first.) ==> ok If you reset the repository and load Paper from database with Paper select all and make the same check, the references are lost. VORepository current reset. theReloadedPaper := Paper selectAll first. self assert: theReloadedPaper planet = theReloadedPaper star planets first ==>not ok But if you remove the comment within >>mongoPlanets which leads to sending a message to the newly loaded object, then it works. write: [ :star :planets | star planets: (planets "select: [:each | each someMethod]") ]); Do I have to send a message to each of the instances after loading? I think no. If I did not understand correctly how to use voyage, please tell me.

Re: [Pharo-users] Slot questions
by Paul Davidowitz June 2, 2015

June 2, 2015

To Camillo Bruni: I'm not using any slot image (I only looked over the paper). According to the Pharo book, 'pvt' should be implemented in the mainstream image. To Marcus Denker: There are actually several methods in the image with the 'pvt' prefix. Please update the doc (Pharo book) to remove talking about 'pvt'. It would have saved me a little headache :)

funny idea Symbol vs. Selector
by stephane ducasse May 14, 2015

May 14, 2015

Hi guys I'm thinking aloud... I was wondering if we could not take advantage of a new class: Selector. MethodDict would only contain selectors and not symbols. I remember that I talked about that with hernan. Stef

How do I save contents of Workspace into a collection?
by Frank Church Jan. 31, 2015

Jan. 31, 2015

Hi guys, My images are gathering a number of Workspaces whose contents I don't want to delete. I want to create a collection of Workspace contents along this defintion: Description Date Category Content (the actual text in the Workspace). In the final version I would like to be able to select a workspace and simply click a button or a menu item and get a dialog where I can enter the Description, Category and Date with the Workspace contents automatically captured into a text box. Copying and pasting the contents would be okay to start with. Filing it out would be another aspect later. What kind of array would best suited to the task? There is quite a number of them depicted here: http://www.jmcsweeney.co.uk/computing/m206/collections_intro.php What could be the best way to go about it? For those who are curious I am experimenting with the original ideas of Smalltalk where a computer user would do everything in Smalltalk workspace/desktop. I am intrigued by the possibility and somehow it seems eminently doable. -- Frank Church ======================= http://devblog.brahmancreations.com

Slots
by Thomas Worthington May 19, 2014

May 19, 2014

I notice that "Slots" are slated for addition in Pharo 3.0. Is there anywhere I can see which model of "slots" is being suggested? I'm not sure that slots, in the sense of Javascript, are a good idea generally and, in the broader context, I'm very unhappy with the idea of messing with Smalltalk's generally clean syntax by adding new language features. Could the desired effects be achieved by subclassing Behavour or somesuch high-level approach? -- Thomas Worthington

NeoJSON and inheritance

How is inheritance supposed to work in NeoJSON? I only figured it out by doing that manually: neoJsonMapping: aMapper super neoJsonMapping: aMapper. (aMapper mappingFor: self) mapInstVar: #longitude; mapInstVar: #latitude. Is there a better way to do? Norbert

SerialPlugin on MacOS
by Bernat Romagosa Feb. 20, 2014

Feb. 20, 2014

Hi list, Developing a multi-platform application is not so easy when you have to deal with hardware it seems... So I'm having this PrimitiveFailed error on MacOS, using the latest stable VM listed on the pharo-project website on Pharo20: *PrimitiveFailed: primitive #primWritePortByName:from:startingAt:count: in SerialPort failed* The same code works fine both in Gnu/Linux and Win32, so I'm guessing it's a problem with the serial plugin included in this VM. Any ideas? Cheers, Bernat. -- Bernat Romagosa.

PharoLauncher as the default Pharo download
by Andy Burnett Jan. 27, 2014

Jan. 27, 2014

á§ That is a good question. I have to admit that I do use iTunes, and I have often been annoyed by not being able to - easily - find the files. I can certainly see the value of presenting end users with simple interfaces, but I am with Johan, I would like to be able to put my images somewhere more obvious - to a developer - particularly because this would make Dropbox/google drive synching easier. Obviously, we can do all of this, but it has never been quite as obvious as I would like it to be.

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. 1, 2014

Jan. 1, 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.

Peter, I don't know the current state of Android's VM. It is, however, fully functional on ARM as I regularly run it now my Raspberry Pi both under Linux and RISC OS. Note, however, that -at least the version for the RasPi- is not a COG VM. So running Pharo in the RasPi is slow given the limited resources of the RasPi. Best Nacho *Lic.

Hi pharoers Sometimes I think that we are crazy to build this system but this is really important to have dreams and make them becoming true. :) I really like what we are doing: we are building a strong community and a really great system. Of course it could be better but it is going in the right direction at full speed. Now remember that Pharo is not ours but YOURS and you can get an impact! Pharo is not read-only. This year we got some nice and important changes. I think that in 2014 we will have some important improvements. We will have to finish what we started and build a solid ground for the next iteration. I really like our community because it pushes me forward and because my dreams are becoming reality :) I wish you a lot of success and health. Stef

towards moose in the pharo ide (gtinspector / gtdebugger)
by Tudor Girba Jan. 1, 2014

Jan. 1, 2014

Hi, Some of you asked how the GTInspector and GTDebugger are different from the existing infrastructure. They are quite different from the norm in that: they are tiny, and they are highly extensible. Here are some posts that describe what makes them different: http://www.humane-assessment.com/blog/the-moldable-gtinspector-deconstructe… http://www.humane-assessment.com/blog/dissecting-the-gtinspector/ http://www.humane-assessment.com/blog/extending-variables-shown-in-gtinspec… http://www.humane-assessment.com/blog/moldable-gtdebugger These tools are already the default development tools in the Moose image. As you can see, Moose is reshaping the Pharo IDE. I think this is exciting. This should be just the beginning. To make it better, we need your energy: - Apply and extend these tools for your context (this is what makes them unique). - Tell us what works and what does not work. - Ideally, start working with us on this topic. In particular, I am looking for people that would like to spend some time working on Morphic widgets. It's your turn now. Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

Re: [Pharo-users] Is there any fundamental technical barrier to compiling to JVM byte codes?
by Andy Burnett Dec. 30, 2013

Dec. 30, 2013

<<<From: St?phane Ducasse <stephane.ducasse(a)inria.fr> The fun is important. What we want is well designed and powerful libraries that enabled people. For the JVM question: it is a question of resources + the fact that jvm do not really support well some key smalltalk operations. Now I do not understand why people develop their own vm instead of joining forces. Doing in the long term something and finishing a task are the most difficult things. Stef á§ >>> Thank you to everyone for your comments. I am replying to Stephane's email, just as a catch all. I am curious to know more about the limitations in the JVM. My thinking was sparked - in part - by Mark Roos's work on RTalk. I realised, after my post, that he had actually worked the other way around, i.e. I think he built a Digitalk bytecode layer on top of the JVM, rather than compiling to JVM bytecodes. Either way, what I was vaguely wondering about was how difficult it would be to have a 'compile to JVM' option in Pharo. I could probably live - quite happily - developing in 'real' Pharo, and then deploying an app to e.g. Google App Engine, as a compiled Jar. Obviously, it would be much better to retain all the dynamism of a true Smalltalk environment even when the app has been deployed, but it it gave simple hosting, and scaling, it might be a reasonable trade off. I agree with Stephane, it would be great for people to join forces around a vm. Would make like so much easier. Cheers Andy > >
