"Theming" dictionaries?
by Offray Vladimir Luna CÃ¡rdenas Feb. 19, 2020

Feb. 19, 2020

Hi, As some of you may know, I'm a "savage coder" who learned Smalltalk/Pharo by himself, of course thanks to communities, books and videos, but without formal training or peers in the same country and guided mostly by necessity. All this to say that this maybe kind of a silly question. Anyway, we have this project called Minipedia[1], that imports Wikipedia articles and their history. A Minipedia language there, is just a dictionary, where the key is the language two letters code and the value for each key is an array of article titles. There is any way to specialize a Dictionary to tell it, name your 'key' as language and your 'value' as 'titles'? [1] https://mutabit.com/repos.fossil/minipedia/ Thanks, Offray

Ubuntu64 install fine, would like to port to Slackware64
by tty Feb. 18, 2020

Feb. 18, 2020

Hi Folks, Pharo 64 launch on Ubuntu 64 launches fine. When I launch Pharo 64 on Slackware 64 I get library call errors . This is probably because Slackware64 stores its libraries in /lib64. Ubuntu stores its 64 bit libs in /lib I much prefer Slackware to Ubuntu. Is there a variable I can set within the Pharo Launcher or elsewhere to have it hit the /lib64 location ? thanks in advance -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

About DuneSt / ChartJs
by Sven Van Caekenberghe Feb. 18, 2020

Feb. 18, 2020

Hi, I am trying to use DuneSt / ChartJs [ https://github.com/DuneSt/ChartJs ] and it looks good. Thanks for another nice library. My first question is about loading the code. I would like to load the minimum possible. I guess the stylesheet code is needed, but not the prism code ? NeoJSON and Seaside are already in my project's dependencies, but Seaside3 seems to never resolve to the same thing, so I would like to skip that. Is that possible ? I have this issue often with Seaside. I could fork and edit the baseline, but I'd rather not. I got a Bar chart on 2D data running right away. But how can I use 'horizontalBar' as type ? var myBarChart = new Chart(ctx, { type: 'horizontalBar', data: data, options: options }); I see that the types are encoded a classes, but the list seems rather limited. Thx, Sven

Pharo at the free software event at Lyon
by HilaireFernandes Feb. 17, 2020

Feb. 17, 2020

Hello, The 4 & 5 of April there is the free software event at Lyon[1]. I am planing for a DrGeo presentation. It will be cool to present Pharo too. The thematic of this event is "pragmatic and accessible Utopia"[2], and we know Pharo is a pretty good match thanks to its ease of learning from running code and modification capabilities. Will any of you interested to join for a Pharo speech?

[ANN] Round 2 Results Are In
by Richard Kenneth Eng Feb. 16, 2020

Feb. 16, 2020

https://youtu.be/B2pNMKuuyKw Watch the robot 'A' as it manoeuvres around the board following the team's prescribed strategy. The robot consumes the energy value of each cell it enters. The cells in blue have *negative *energy values! The object is to maximize the score. The winning team comes from Nepean High School in Ottawa, Canada. Next week's round, Round 3, is particularly interesting. The board will contain Death cells (if the robot enters one, it dies and the simulation is terminated), Jump cells (where it jumps ahead n cells in the direction it's moving), and Warp cells (where the robot "warps" to another location on the board). The Round 3 map I've created for the board is particularly challenging. I can hardly wait for that round! Richard

Re: [Pharo-users] can I write this without the three if then;s
by Dennis Schetinin Feb. 15, 2020

It would be an overkill to do it for this particular case, but Smalltalk makes it possible to implement a case-like construction: [ expression ] when: [ :value | condition1 ] do: [-0do :value | ... ]; when: [ :value | condition2 ] do: [ :value | ... ]; otherwiseDo: [ :value | ... ]; evaluate I am sure, something like this has been implemented already somewhere (maybe in Squeak?). Still not sure it is practical as compared to simple if-s, and for sure not widely used :) ...On the other hand, sometimes the case-like construction can be considered a more intension-revealing style.

Developing on Mac Catalina 10.15
by Maximiliano Tabacman Feb. 15, 2020

Feb. 15, 2020

Hi. The Pharo application I developed is offered to users in Windows, Linux and macOS based on the three VMs available on the Pharo website.I basically download the VM, add my image and some resources, rename stuff and put a nice icon, and it's ready to be deployed.Now, since mac updated their users to Catalina (10.15), I've noticed that my application won't work anymore, and it seems to be related to the signature required by Apple. If I download the Pharo VM fromÂ https://files.pharo.org/get-files/80/pharo64-mac-stable.zipand run it, it works. If I open the package contents and add stuff inside the /Resources directory, the application seems to still be working (with those minor changes it would even still just open Pharo and not my app).BUT if I upload it to my Google Drive, and then download it, it no longer works, stating that it's broken and must be moved to the trash. If instead of adding stuff inside I just rename it and change its icon, I can upload and download it and it opens Pharo normally. So I'm guessing, since the _CodeSignature directory was not present in older Pharo Mac VMs, that someone knows how to work with those signatures, and that it must be the key that's missing to make it work. Can anyone point me in the right direction? Any tutorial, mail discussion, or whatever that might tell me how they made it work for Pharo might help me make the changes I need to the .app and get my product working. Thanks!

[ANN] Teachable on GitHub
by Torsten Bergmann Feb. 14, 2020

Feb. 14, 2020

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 Feb. 14, 2020

Feb. 14, 2020

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.
