Question on Behavior>>superclass:

by Jordi Delgado

Hi, This example in the slides of Pharo MOOC, week 7, is broken in Pharo 7.0 (the variable newClass is not used, thus it has been removed): | behavior model | behavior := Behavior new. behavior superclass: Model. behavior setFormat: Model format. model := Model new. model primitiveChangeClassTo: behavior new. self assert: model class = behavior. self assert: model class superclass = Model. behavior compile: 'foo ^ 2'. self assert: model foo = 2. self should: [Model new foo] raise: MessageNotUnderstood (slide 14 in http://rmod-pharo-mooc.lille.inria.fr/MOOC/Slides/Week7/C019-W7S04-OtherRef…) The code is broken because there is no method Behavior>>classInstaller, and the message classInstaller is sent to self in Behavior>>superclass:. Adding a Behavior>>superclass2: to Pharo 7.0, copied from Pharo 6.1 Behavior>>superclass:, and using Behavior>>superclass2: in the example: | behavior model | behavior := Behavior new. behavior superclass2: Model. "<-------" behavior setFormat: Model format. model := Model new. model primitiveChangeClassTo: behavior new. self assert: model class = behavior. self assert: model class superclass = Model. behavior compile: 'foo ^ 2'. self assert: model foo = 2. self should: [Model new foo] raise: MessageNotUnderstood the code works again and the example is good. However, this is only an ugly workaround. Thus: I do not know why Behavior>>superclass: was changed in Pharo 7.0 but I guess it was not an accident. I assume it has to do with deep changes in the low level structure of the implementation of the language, having to do with slots, etc. I have browsed Pharo issues in github but I did not find anything related. Also, I'm not sure this problem qualifies as an "issue". So, my question is. Is it possible to easily adapt the example to the new Pharo 7.0? (with no silly workarounds, I mean). Thanks in advance and, as usual, apologies if the question is trivial and/or stupid.

Thanks sean for the feedback Now pay attention that we cannot digest fast non PRs because we are super busy with P8 alpha. Can you open an issue so that martin can get an idea of what should be improved? Stef > On 18 Aug 2019, at 21:41, Sean P.

Code Completion: GSoC project summary

by Myroslava Romaniuk

Hi i just published a summary of my work on code completion during Google Summer of Code, for those who are interested. It's a 5 min overview of the progress that was made and some further plans (i do intend to continue working on it, as there's still cool things to be done). Here's a link to the blog post: https://medium.com/@myroslavarm/code-completion-in-pharo-gsoc-project-summa…, and the tweet: https://twitter.com/myroslavarm/status/1164059233073147905, if anyone feels like spreading the word. Thanks so much, Myroslava PS there's going to be a talk at ESUG Marcus and I are doing, please come!
