by Tim Mackinnon Aug. 20, 2019

Aug. 20, 2019

Iâm not sure if this is interesting to the wider community - but Iâm always genuinely impressed that we continue to get a good trickle of solutions submitted to Pharo Exercism - and Iâm genuinely impressed that there is a team of folks who quietly coâhelp in mentoring students and giving feedback to solutions (thanks guys). Its very impressive.

Expression to load a single package from a git repository
by Alejandro Fernandez Aug. 20, 2019

Aug. 20, 2019

Hi all, can anyone point me to a (Metacello?) expression to load a single package from a git repository (I have no project, or baseline, or configuration defined)? The repository is a collection of packages that are supposed to be loaded one by one, on demand (e.g. independent examples or exercises). I am using Pharo 7 (on Pharo 6 I used to do this with IcebergRepositoryCreator and #updatePackage: which does not exist in Pharo 7). Thanks in advance, Yours, Alejandro

Is anyone maintaining garage? I get some errors in Pharo 7, which I have patched as I have needed to. Looked in the GitHub repository and last update was back in September. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

As a SmallTalk youngster: A few questions...
by ian Aug. 17, 2019

Aug. 17, 2019

Hi All, Learning; Please bear with me. Scenario: 1. Class>>User. InstVars: #(this that other userStatus userMeta) 2. Class>>UserManager (singleton). Instvars: users (RcIdentityBag: users) When User is instantiated all its' instVars are populated correctly. Nested objects as well. To insert the User into the UserManager singleton instVar I created an add: method on the instance side of UserManager to pass the User to the UserManager as per: --- add: aUser users add: aUser --- This works and I am able to created my database of users. The difficulty I am having is that when I want to query the UserManager db with something like: --- RcIdentityBag(users) select: [ :each | each name := 'somename' ] --- It seems that currently the only I know how to do this is to create a select: method in UserManager simply to pass the desired search string into the UserManager class such that I can use the Collection Classes api to do the actual work, as per: --- Pardon the not so smalltalky code --- UserManager>>select: aString | resultSet | resultSet := users select: [ :each | each name := aString ]. ^resultSet --- I believe I read somewhere that in order to avoid this clunkiness that I could refer to the users collection in UserManager via a symbol and access the api of the identitySet directly. Something like: --- UserManager class>>current UserGlobals at: #FOO put users. ... --- But when I do this I am unable to do something like: --- #FOO add: user --- Do to doesNotUndestand exceptions. Finally Questions: 1. Am I totally off the mark with the use of smalltalk symbols? 2. Must I create the API in the managing class to perform the specific functions I need from the collection API with respect to querying the collection? 3. Is there a smalltalk way of doing this properly that I missed (reading all the docs I can find in random order based of info I need - probably missing the finer points)? Any nudge in the correct direction would be greatly appreciated. Thanks!

finds replacements for deprecated objects
by Steve Quezadas Aug. 16, 2019

Aug. 16, 2019

Forgive the naive question here. But if an object gets deprecated, how do you find the closest replacement object in Pharo? Is there a way to do it within the VM or do you just have to check the documentation? - Steve

[ANN] Pharo Chip Designer
by Pavel Krivanek Aug. 15, 2019

Aug. 15, 2019

Hi, I have created a little program based on an old educational game by Zachtronics (KOHCTPYKTOP: Engineer of the People[1]) named Pharo Chip Designer. It is an inaccurate and highly simplified tool for the design of silicon chip layouts. Unlike common tools for logic circuits designs, in Pharo Chip Designer, you need to face the real-life problems like propagation delays or limited amount of layers and available substrate area. https://github.com/pavel-krivanek/PharoChipDesigner <https://github.com/pavel-krivanek/PharoChipDesigner/blob/master/README.md> It contains levels from the original game, but you can play with your custom designs on larger surfaces. And of course, use all the Pharo power to control the I/O signals. The Pharo Chip Designer required Pharo 8.0 and Spec2. Cheers, -- Pavel [1] http://www.zachtronics.com/kohctpyktop-engineer-of-the-people/
