Mean time, you can report the Google Drive ZIP files for abuse to Google. I think you have to be logged in to Google and then you put the ID from the ZIP file's URL at the end of the following URL: https://drive.google.com/u/0/abuse?id= On Fri, 14 Feb 2020 at 17:29, phil(a)highoctane.be <phil(a)highoctane.be> wrote: > This is spam from some hacker. > > Replaced all passwords on my side and enable 2FA where not done yet. > > > Sorry for the noise. > > Phil, the real one > >

This is spam from some hacker. Replaced all passwords on my side and enable 2FA where not done yet. Sorry for the noise.

I got three emails in quick succession to widely different accounts.

Hello everyone I have received this e-mail, and another one from Phil quoting the same download link in an entirely different context. I have not downloaded it, because I think there is something suspicious about it. Has anyone else any suspicions? Has someone hacked into my e-mail, or is it this list that has been hacked?

[ANN] Teachable on GitHub

by Torsten Bergmann

I moved Teachable project now to GitHub: https://github.com/astares/Pharo-Teachable The Project shows the power of Smalltalk meachanisms within Pharo and can be useful for dynamic mock object building in unit tests. Docu and load instructions are included in the project site. Side note: ========== You can also easily load it via catalog within Pharo 8/9: - take a fresh clean Pharo image using PharoLauncher - click on "regular network connection" in the Quick setup sectiono of Pharo welcome window (this allows spotter to show catalog projects) - open Spotter (SHIFT+ENTER) and key in "Teachable", hit ENTER to load via catalog Another possibility is to search for "Teachable" in Catalog utility directly (Tools -> Catalog Browser). Have fun T.

[ANN] Pharo-YUML

by Torsten Bergmann

Hi, I published some very simple utility code on https://github.com/astares/Pharo-YUML to easily generate links for YUML. Use the load expression given on the project site or load "YUML" from catalog. Allows you to get a class hierarchy image of an existing Pharo class. It could help to include simple class hierarchy pictures into your (markdown or other) documentation. Example: YUMLGenerator open: String opens a browser to let YUML generate the class hierarchy of String. The clip the URL to your docu as image, for instance in markdown write: ![Hierarchy of String](https://yuml.me/diagram/class/class/[String],[String]%5E-[ByteString],[String]%5E-[Symbol],[Symbol]%5E-[ByteSymbol],[Symbol]%5E-[WideSymbol],[String]%5E-[WideString]) If you need the URL directly then use YUMLGenerator new generateHierarchyFor: String Docu is in https://github.com/astares/Pharo-YUML/blob/master/README.md including an example picture. Maybe it is useful for others too. Thx T.

enhance object presentation in the inspector for documentation

by Renaud de Villemeur

Hi all. I really like the ability we have in the browser to set and signal method with sample code so we can run them easily by a simple click. The pragma <example> or <script: > are really helpful to document entry point or keep example as small script directly with the code. To have a better grasp of certain object I create, I look at the possibility in the inspector to provide custom object representation. It look like if I add the pragma <gtInspectorPresentationOrder: XX> to some method, it will be added in the inspector as an extra tab with custom representation. Morphic widget are a good example of this. With a quick investigation, I can see that the presentation in those tabs are done by instances of GLMCompositePresentation Given all the discussion I can see on Glamour and GToolkit (for example https://discordapp.com/channels/223421264751099906/445970167495786497/64814…) <https://discordapp.com/channels/223421264751099906/445970167495786497/64814…>, I was wondering if it's was worth the time to understand how to create custom object representation with Glamour or if it will be deprecated in Pharo 9, and what could be the alternatives. Any advise/comment would be welcome. Renaud

Re: [Pharo-users] Setting a model for a Spec UI in Pharo 8

by Renaud de Villemeur

Hi Bren. Are you doing it with Spec2 ? >From my understanding, Spec2 is an MVP framework (Model-View-Presenter) - The model represent the domain logic of the application - The presenter let the developer do the UI programmaticaly and connect it to the Model. - The UI drawing is then managed by Pharo through the Spec2 interperter. First, I subclass Model for my domain model class. For the UI, I subclass SpPresenterWithModel. In the UI >> initialize method, I set the model with something like: 'self model: MyModel new' In the UI >> connectPresenters, when one of my value changed, I called 'self announcingObject valueChanged' I also overwrite UI >> modelChanged with 'self fillFormWithWorkingModel', where fillFormWithWorkingModel link the UI to the model to reflect change. If you want to look at a fully working example, you can take a look at my sourdough calculator: Metacello new baseline: 'Sourdough'; repository: 'github://rvillemeur/Sourdough/src'; load It's a small project for calculating sourdough proportion when doing bread. The model is doing basic proportion calculation (the project includes tests). The UI is using Spec2, and is connected with the model. Hope this helps.

Re: [Pharo-users] Setting a model for a Spec UI in Pharo 8

by Bren

ï»¿Hi fellow Pharo folks, TL;DR: The only apparent way to open a standalone presenter on a user-specified model, SpPresenter>>on:, has a comment suggesting it will be deprecated. As a follow-up to my previous question in case someone DuckDuckGoes it in the future, it seems that adding self modelChanged to SpPresenterWithModel>>setAnnouncingObject: breaks the Spec2 demos. So, I backed my fix out of my image. This has several implications: - To actually change an SpPresenterWithModel's model, one must send model: and then modelChanged. This seems to break encapsulation. - The Spec2 demos seem to rely on modelChanged not arriving before the UI opens. This seems fragile, and reduces the utility of using the demos as examples for writing non-demo code. - Since I can't send modelChanged from model:, I must apparently use SpPresenter>>on: to open a standalone instance of my subclass of SpPresenterWithModel on a model I supply (e.g. (BLFunctionPresenter on: aModel) openWithSpec). I was avoiding this because unfortunately, the comment foreshadows deprecation but does not explain what to use instead. I do not understand how a subclass of SpPresenterWithModel can be composable after this deprecation. So, I have a solution for now, but I am still looking for the supported way to open a standalone presenter on a user-specified model.
