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

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

if Pharo is key for you
by StÃ©phane Ducasse Jan. 18, 2015

Jan. 18, 2015

Hi guys if Pharo is key for you then you should ask yourself what you did for Pharo recently. Writing code, writing documentation helping closing bug entries, participating to the association, to the consortium... Pharo is not happening from spontaneous generation. Stef

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
by Norbert Hartl March 22, 2014

March 22, 2014

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

Call for Participation in the Smalltalk Devroom at FOSDEM2014
by Stephan Eggermont Jan. 13, 2014

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.

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.
