Seems that Pharo is a magnet for this kind of project. I've been writing one as well and using it to organize my research notes. Does anyone working on personal info mgmt tools want to talk offline? I expect we're running into some of the same issues, both conceptual and technical. Evan

Aggregation framework in MongoTalk?
by phil＠highoctane.be Feb. 18, 2019

Feb. 18, 2019

Is there anyone using the aggregation framework of MongDb through MongoTalk? It uses the aggregate() command, so I was wondering if this could be supported out of the box or if there is a need for an additional Operation. TIA Phil

Retina support in Pharo
by markm Sept. 20, 2018

Sept. 20, 2018

Hi Is it possible to get Pharo (4 or 5) to run with retina support on OS X? I have tried searching for some answers, but alas could only find a handful of posts from a few years back. Any help much appreciated! Mark -- View this message in context: http://forum.world.st/Retina-support-in-Pharo-tp4895245.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Hi, I'm getting this error while trying to prototype some interface with Spec on Moose 6.0: MessageNotUnderstood: ToolDockingBarMorph>>popUpOwner it happens anytime that I'm using displaying a MenuModel and I go to the menu items. I imagine that the menu item is complaining about a lacking pop up message. How can I solve this? Thanks, Offray

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

Hello, On Pharo4, when I type the command: OSProcess waitForCommand: 'ls' it locks the image, I can get back control with [Alt]-. With the same image and VM, this command was previously working, even called from a Seaside component. Any idea? Thanks Hilaire -- Dr. Geo http://drgeo.eu

[ann] pillar text editor
by Tudor Girba Nov. 15, 2017

Nov. 15, 2017

Hi, Pillar now ships with a text editor that also features a syntax highlighter. So, now, if you load the development version of Pillar: Gofer new smalltalkhubUser: 'Pier' project: 'Pillar'; configuration; loadDevelopment. You will have an extra presentation when inspecting a .pillar file: The new thing here is that the highlighter is based on the Pillar PetitParser, and it is extensible for highlighting more parts if needed. The highlighting also can support actions. For example, the picture above shows the file to the right after clicking on the reference. Please take a look and let me know what you think.

How to view hierarchy of multiple classes in a package?
by Tim Mackinnon July 8, 2017

July 8, 2017

Hi guys - I'm trying to get back into pharo, and check out the advances in v5. Anyway, if I look at a package in the system browser, it shows me classes in that package (i think my terminology is right here?). What confuses me, is his I can see the hire hybrid the classes in relation to each other? The hier button just shows the hierarchy of the selected class and not in relation to the others? I'm sure at some point pharo and squeak let you see the related hierarchies of all the classes in the package didn't it? This is really useful to help understand the relationship between classes and pure risky identify useful refactorings. I can't see how to do this in pharo anymore? Is this functionality that has been lost (which seems a shame)? Or am I missing another useful browsers? Tim Sent from my iPhone

Pharo6 server deployment and no home directory
by Holger Freyther June 18, 2017

June 18, 2017

Hi, as Pharo6 is around the corner I have moved my CI build from tracking Pharo5 to Pharo6 but I run into a problem. Either if $HOME is not set at all or $HOME points to a wrong directory I run into the error below. As this is a server application and I run multiple VMs with the same image and there is no home directory I would prefer that no information is persisted at all. Can this be done? Have there been any changes in Pharo6 in regard to this? It also seems to change from Fuel->Ston for the identifier?

[Modeling with Pharo] How to model a simple human interaction.
by sergio ruiz June 10, 2017

June 10, 2017

Hey all.. I got my first paying gig that i am able to use pharo with, and i am on the last leg before calling it complete. Hereâs what I need to do.. This application accepts SMS text messages. It allows the user to send images via MMS and place an order to a print house for those images.. Â it then compiles the order, and submits it to the order processing system and makes the prints. The last thing I need to zero in on is handling the interaction. Believe it or not, I have never modeled such an interaction. The interaction goes: - user sends images{s) - bot says âthanksâ and asks if there are more - user types âdoneâ or sends more - on âdoneâ bot asks for print size - bot says âthanksâ and the interaction is done. order is processed. my first inclination is to use a state machine, progressing through order each time the user enters âdoneâ..Â does this sound reasonable, or is there a better model/design pattern for this interaction? Thanks! ---- peace, sergio photographer, journalist, visionary Public Key:Â http://bit.ly/29z9fG0 #BitMessageÂ BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.Village-Buzz.com http://www.ThoseOptimizeGuys.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Epicea vs RB refactorings
by Peter Uhnak May 10, 2017

May 10, 2017

Hi, I'm under the impression that Epicea is supposed to replace RB refactorings at some point. If that is true, is it currently possible to build refactorings by hand? For example in RB I often do: ``` model := RBNamespace new. model defineClass: ('<1s> subclass: #<2s><n><t>instanceVariableNames: <3p><n><t>classVariableNames: ''''<n><t>poolDictionaries: ''''<n><t>category: <4p>' expandMacrosWith: 'Object' with: 'MySomething' with: 'var1 var2' with: 'MyPackage'). cls := model classNamed: #MySomething. cls compile: 'var1 ^ var1' classified: 'accessing'. (ChangesBrowser changes: model changes changes) open ``` or (removing a method from a class) ``` model := RBNamespace new. model removeMethod: #testTrimRight from: StringTest. (ChangesBrowser changes: model changes changes) open ``` Thanks, Peter

using UFFI in non-crashing way
by Peter Uhnak May 7, 2017

May 7, 2017

Hi, is it possible to use UFFI and avoid crashing the image when the called code segfaults? In other words, can I somehow wrap the call and throw in-image Exception/Error on failure instead of the whole thing crashing? Or is the only way to do that have the called thing running as a separate app (e.g. via OSSubProcess) and communicate via pipes or sockets? Thanks, Peter

[Ann] Pharo Sprint App to improve coordination during Pharo Sprints
by Juraj Kubelka May 2, 2017

May 2, 2017

Hi, We are happy to announce a new application called Pharo Sprint App. The main idea of the application comes from the whiteboard that have been used during Pharo Sprints and was also adopted in Chile. As the Pharo Sprint is organized in several places around the world, we miss the connection with other guys. For that reason we decided to move the physical whiteboard to the internet and developed Pharo Sprint App. How does it work? Participants choose a case from the âproposed' or âallâ list. Once they are done, they move it to the âdoneâ list. We believe that the application will encourage other people, especially newcomers, to join us during the events and have a fun, together with other developers. How To Use It? â¢ Download the latest image from Bintray <https://bintray.com/jurajkubelka/PharoSprint/build/_latestVersion#files> â¢ Execute the image, using the corresponding VM for Pharo 6 â¢ Run the application from World Menu / Communication / Pharo Sprint â¢ Login, using your FogBugz account, wait a bit, then choose a case and have a happy programming :-) Everybody participating in the sprints should use the Pharo Sprint image. The upcoming event is on Friday April 28: https://association.pharo.org/event-2492488 <https://association.pharo.org/event-2492488> The application is deployed in Pharo 6 (32 and 64bits). More details are available at: https://github.com/JurajKubelka/PharoSprint <https://github.com/JurajKubelka/PharoSprint> I will appreciate any feedback. Have a fun! :-) Juraj

improving audio/video quality of pharo days recordings
by Peter Uhnak May 1, 2017

May 1, 2017

Hi, we had a small discussion on discord about improving the audio/video quality of recordings of past pharo days, where many recordings are really hard to see (or completely unreadable), or the presenter is really hard to understand (especially if they speak quietly or have a strong accent). Obviously making really good recordings requires several people to focus on it (which is hard on a small meetup), however two things could be imho introduced that could help a lot, with little demand on attendees. 1) clip-on microphone * camera's mic will not capture good sound from 10 meters away over a crowd of people making noises 2) VGA recorder (which goes between the presenter's computer and projector) * then we would have crisp video and not relying on the quality of the camera in fact this is very common format where in the final video you see primarily the VGA output, and not camera capture from a distance (only on the presenter), e.g. https://www.youtube.com/watch?v=XA2WjJbmmoM Unfortunately I am not attending Pharo Days this year (scheduling conflict), so I can't help on-site, but I could help with post-processing where possible, e.g. converting the raw audio/video/VGA streams into one (as in the linked video) or something.

VoyageMongo questions
by john pfersich April 30, 2017

April 30, 2017

Has anyone tried to use VoyageMongo to connect to a MongoDB instance not on the local machine? I used the VoyageMongo from Smalltalkhub like the "Persisting Objects with Voyage" said and it looks like I had the same problem that Sabine mentioned on Discord; "Not enough space for external objects, set a larger size at startup", but there was a (another) problem and the image was toasted. I then tried to load VoyageMongo into Pharo 5 from the Catalog Browser and there's an error and it won't load. Any hints on what I'm doing wrong? I'm using Pharo5.0 Latest update: #50761.

Implement Matrix whith OrderedCollection
by frankl1_miky April 30, 2017

April 30, 2017

Hi everyone, I'm figuring out a strange behavoir with OrderedCollection. Actually I've created a matrix using OrderedCollection like this: /c := OrderedCollection new: 16 withAll: (OrderedCollection new: 16 withAll: 0). c./ But when I try to set the value at row 1 and column 2 to be 50 like this: /(c at: 1) at: 2 put: 50/ I instead get 50 in any cell of the second column and I don't know why. When using a Matrix and the massage at:at:put, the behavoir is normal. Why that strange behavoir with OrderedCollection? -- View this message in context: http://forum.world.st/Implement-Matrix-whith-OrderedCollection-tp4945002.ht… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Process scheduling
by raffaello.giulietti＠lifeware.ch April 30, 2017

April 30, 2017

Hi, I can't find a description on how ProcessorScheduler in Pharo (i.e., Cog) is supposed to do context switches in absence of other synchronization points. Is it following the BlueBook spec? Just to recall that model, the VM, when about to execute the current bytecode instruction of the current Process, checks whether a strictly higher priority Process is ready to run and if so, switches to (one of) the highest priority among them. Thanks in advance for clarifications. Greetings Raffaello

Dark theme and white vs. green color
by Juraj Kubelka April 30, 2017

April 30, 2017

Hi, While we were improving the DiffMorph for the dark theme, we conclude that it is much harder to read the text. I personally also often miss a new debugger window on a big screen. Something I have not experienced before. And this discussion reminds me the old computers where the background was black and text green. There are two screenshot to compare it: A personally feel that it is much easier to read the green text. What do you think? Juraj
