Pharo Quality Rules for Beginners
by ESTEBAN VILLALOBOS DIAZ Jan. 15, 2020

Jan. 15, 2020

Hello everyone! My name is Esteban and I will be working on the Pharo Quality Rules for the next few months. The goal is to create different profiles for the rules according to the programming experience of the user. For example, for the beginner profile we would like to check for common mistakes made by people who are just starting with Pharo like: - Sending self as a message (probably because they forgot a . ) - Using False instead of false - etc.. I would appreciate it if you could share with me other common mistakes that you have seen beginners do, or maybe tell me a bit of your own experience when you started using Pharo :) Best, Esteban Villalobos

GitHub Organizations 1...*Infinity
by Sean P. DeNigris Jan. 14, 2020

Jan. 14, 2020

It seems we have a new Pharo GH organization every day! There is for example (pharo-project, pharo-vcs, pharo-rdbms...). The problem is that each of these creates another entry point that must be known to users, and therefore another list for us to manually maintain, and we know the struggle of keeping docs in sync quite well. My question is: why can't we consolidate into a few general buckets (like one for official and one for community) and manage the categorization with GH topics (a.k.a. tags) and teams? Here's a discussion of this idea: https://github.community/t5/How-to-use-Git-and-GitHub/Structuring-repositor… IIUC you can use teams to scope the access for each repo. With topics/tags, someone could just go to the one organization and search for vcs or rdbms to see a list of just those repos. Here's an example of a saved search like that: https://github.com/atom/?utf8=â&q=topic%3Apackage&type=&language= ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html

Reserving/allocating some slots in the specialObjectsArray for DoubleByteArray, WordArray and DoubleWordArray
by Eliot Miranda Jan. 14, 2020

Jan. 14, 2020

Hi All, currently the following slots in the specialObjectsArray are unused in both Squeak and Pharo (& I suspect Cuis). newArray at: 32 put: nil. "was the prototype Float" newArray at: 33 put: nil. "was the prototype 4-byte LargePositiveInteger" newArray at: 34 put: nil. "was the prototype Point" The specialObjectsArray already contains ByteArray newArray at: 27 put: ByteArray. I would like to have a full set of little-endian unsigned integer arrays. In Spur Squeak these are ByteArray, DoubleByteArray, WordArray (Bitmap is big endian), and DoubleWordArray. The VM's at:[put:] directly supports these four at the JIT level giving us efficient unsigned access. There is also efficient signed access for some signed arrays but these are less useful (at least in theVM simulator). I want to make all four unsigned integer array classs available to plugins etc via the interpreterProxy. So here's a formal request to reserve these values for use as follows: newArray at: 27 put: ByteArray. ... newArray at: 32 put: DoubleByteArray. newArray at: 33 put: WordArray. newArray at: 34 put: DoubleWordArray. _,,,^..^,,,_ best, Eliot

Iceberg: Why create branch when Reviewing a PR?
by Sean P. DeNigris Jan. 13, 2020

Jan. 13, 2020

When reviewing a pull request, when merging, why does Iceberg prepend the repo name to the branch? It seems to require one to manually checkout the issue branch (and remember not to checkout any packages) in order to modify the code, no? ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html

[ANN] Embedding Image Example (Win)
by tesonep＠gmail.com Jan. 13, 2020

Jan. 13, 2020

Hi, I have produced an example of using the headless VM to have an embedded image in Windows. The example is hosted in Github (https://github.com/tesonep/pharo-vm-embedded-example) The example is a CMake project to generate a new small executable that uses the VM as a library. Also, it shows how to perform the branding of applications (I have used the same Pharo icon, but we can use anything else). In the example, I am opening one of the SDL2 examples, it opens a window where we can draw in an Athens Canvas. It requires a Cygwin environment, but if you are able to build the headless VM you already have it!. I will do other examples of the use case we are thinking for the headless VM!
