Thanks for your response. Yes, type in the select block. Thanks for letting me know I am on the right track...

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/

Bootstrap3 to Bootstrap 4
by Jeff Gray Aug. 15, 2019

Aug. 15, 2019

I have moved my code from using Bootstrap 3 to Bootstrap 4. There were a few updates I had to make and overall it seems cleaner. The one thing I can't seem to convert is informSuccess. There doesn't seem to be an equivalent in Bootstrap 4. For now I am using the vanilla Seaside inform, which is ok but it doesn't look bootstrappy. My use case is when I have performed an action on a page, then I want to display a message and then redirect to a different page. ie on a "I forgot My Password" page I send an email to the entered address. Then I display a message to say that the email was sent. When the user clicks ok they are redirected to the login page. Is there a better way to handle this than with an inform? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

SHA512 HMAC support in Pharo
by Jonathan van Alteren Aug. 14, 2019

Aug. 14, 2019

Hi all, For a client project we need support for SHA512 and SHA384 hashing and digital signatures with HMAC). Can anyone tell me if there is work (being) done on SHA512? We're on Pharo 7.0.3. At first, it didn't look too hard to refactor the SHA256 class in the System-Hashing package. That is... until I saw the use of ThirtyTwoBitRegister and the SHA256NonPrimitive and SHA256WithPrimitive classes in the Cryptography-SHA256 package. It seems to me that SHA512 will need a SixtyFourBitRegister class. Also, when I try to generate the constants on the fly with 64 bit values, the last 3 hexadecimal digits are zero (0). To me, this suggests that Pharo/Smalltalk might have issues working with 64 bit (float?) values. "(Integer primesUpTo: 312) collect: [:x | (((x raisedTo: 1/3) fractionPart) * (2.0 raisedTo: 64)) truncated hex]" Kind regards, Jonathan van Alteren Founding Member jvalteren(a)objectguild.com +31622500930
