class initialization and class-side variables
by Jan BlizniÄenko April 29, 2015

April 29, 2015

Hello It seems I misunderstood some concept of classes in Pharo. My problem is following: Let's say I have class named SomeClass (subclass of Object) and class named SubClass (subclass of SomeClass). If I create instance variable on SomeClass and SomeClass>>#initialize which initializes the variable, it gets initialized also when SubClass instance is created. Now I'm trying to do something similar for class-side variables, but with no success. If I create class-side variable on SomeClass and SomeClass class>>#initialize which initializes the variable, it gets initialized only in SomeClass class, but not in SubClass class. What I mean: Object subclass: #SomeClass SomeClass class instanceVariableNames: 'Ok' SomeClass class>>#initialize super initialize. Ok := true SomeClass class>>#isOk ^ Ok SomeClass subclass: #SubClass calling "SomeClass isOk" returns true. calling "SubClass isOk" returns nil. now If I create method SubClass class>>#initialize super initialize. SubClass initializes as I would expect from my experience with instance initialization, so "SubClass isOk" now returns true. I will appreciate any help.

I found to working solutions which fix issue, also doesn't require symlink in Plugins directory: 1) create plist file in /Library/LaunchAgents which sets library path and Oracle home or 2) create apple script that sets environment variables and run a user login

Understanding Slices
by Sergio Fedi April 29, 2015

April 29, 2015

Are Slices a way to represent a change accross packages? For example, if I add a new functionality, then at least two packages will be modified. The one the feature is imlpemented in, and the one with the tests for that feature. So a Slice could encapsulate these changes to both packages in a single piece. Am I understanding this correctly?

STON references class removed in Pharo 5
by Jan BlizniÄenko April 29, 2015

April 29, 2015

Hello I'd just like to note that STON package is referencing class TimeStamp in its tests, which has been deprecated and got removed in Pharo 5 (since image 50003), so if I want to use latest image (which I do), I get a warning that STON package depends on non-existing class.

April 29, 2015

Hi, we would like to switch our project over to git, however is it possible to preserve the history? I.e. to convert mcz (or wherever monticello stores it) to git commits, or do I have to start from scratch? Thanks, Peter

Oracle FFI - External module not found on OS X
by recursive68＠gmail.com April 28, 2015

April 28, 2015

Discovered the issue, the Oracle FFI wrapper is loading correctly but then is not finding the Oracle Instant Client library correctly. Creating sym links fixes the issue with finding the Oracle Instant Client dylibs but then it still doesn't find Oracle TNS settings etc .. BTW used dtruss (dtrace tool) to track dylib failures.

{ANN] TMM (Teapot, Mustache, Mongo) web application stack
by Yanni Chiu April 28, 2015

April 28, 2015

Hi, I cleaned up and released some demo code I put together for a Smalltalk user group meeting. The code was extracted from a project Iâve been working on. It also uses Magritte3, Voyage, and ZincSSO, but thatâs too many pieces to include in the web-app-stack name I was working in Pharo3, so I took the opportunity to upgrade to Pharo4. I had no problems with Pharo4 itself, but I had some minor issues with the updated Teapot and VoyageMongo versions: - VoyageMongo - <mongoContainer> pragma is now expected on class-side, not the instance-side - Teapot - To read/parse template files on each request (which is convenient during development) I had intercepted an internal API. This API changed slightly, which needed a simple fix, but it was hard to find I also decided to use a âgitâ repository. This turned out to be one of the hardest parts, but I think it was worth the effort. To try TMM, follow the instructions at: https://github.com/yannij/TMM Enhancements are welcome, but I donât quite know how this git workflow will pan out. Iâve already got a few changes to port over: - a more integrated file upload example - an email/passwordHash stored in the User object in mongo. â Yanni
