TelePharo status

by Gerry Weaver

Hello All, Are there any plans to get TelePharo working again? I've been checking when each new version is released, but no luck so far. I haven't tried version 12, because I assume it is not working. I'm thinking about a project where it would be pretty cool to have TelePharo. Unfortunately, I lack the exprerience with Pharo to attempt to fix it myself. -- Thanks, Gerry

This week (30/2024) on the Pharo Issue Tracker

by Marcus Denker

The most important not obvious news of the week: We managed to get the CI in a good shape again! Test are now green for all three platforms. This is one of these aspects of development that are easily overlooked: Just keeping the CI green and running is far more work in a real project than you would naively think. Summer break: the weekly mails (but not the improvements to Pharo!) will take a break. In the week of 26/08 we post the weeksly logs for weeka 31-34. # Pharo 12 Backports - Automatically type 'NULL' arguments in FFI (backport to P12) #16926 https://github.com/pharo-project/pharo/pull/16926 - [Backport] Update FormSet to not recompute each scalling all the time #16887 https://github.com/pharo-project/pharo/pull/16887 # Fixes - Fix bug in protocol management of Traits #16936 https://github.com/pharo-project/pharo/pull/16936 - Instance of NullWorldRenderer did not understand #fullscreenMode: when run headless / in CI #16925 https://github.com/pharo-project/pharo/pull/16925 - Catch CmCommandAborted in Calypso #16920 https://github.com/pharo-project/pharo/pull/16920 - Fixes icon for packages drop list in StRequestClassPresenter #16856 https://github.com/pharo-project/pharo/pull/16856 - Handles permission problems on FileBrowser #813 https://github.com/pharo-spec/NewTools/pull/813 - Use equality to compare file references in file navigation system #811 https://github.com/pharo-spec/NewTools/pull/811 # Improvements - Enable specification of a comparison strategy to compare list items #1573 https://github.com/pharo-spec/Spec/pull/1573 - Improve IconStyler highlight to be base on theme #16943 https://github.com/pharo-project/pharo/pull/16943 - Add isPackage #16935 https://github.com/pharo-project/pharo/pull/16935 # Rules - improve ReCollectionProtocolRule #16918 https://github.com/pharo-project/pharo/pull/16918 - Deprecated package #16931 https://github.com/pharo-project/pharo/pull/16931 - change rules description UI #16929 https://github.com/pharo-project/pharo/pull/16929 # Cleanup - ListView-Tests should depends on Tests #1576 https://github.com/pharo-spec/Spec/pull/1576 - ListView adapters should be close to morphic adapters #1575 https://github.com/pharo-spec/Spec/pull/1575 - Fix dependency test #806 https://github.com/pharo-spec/NewTools/pull/806 - Remove MCMergeBrowser #16950 https://github.com/pharo-project/pharo/pull/16950 - Monticello: remove dead code and some Morphic UI #16949 https://github.com/pharo-project/pharo/pull/16949 - Move UndefinedClassVariable out of the Kernel #16947 https://github.com/pharo-project/pharo/pull/16947 - Remove useless method: CompiledMethod >> argumentNames #16937 https://github.com/pharo-project/pharo/pull/16937

Re: [ANN] class-diff: a new tool for comparing classes

by Tim Mackinnon

Thats a great set of observations Richard - I think I'd want it to work like you have described too - probably showing an inherited method in a light grey to indicate its inherited (but dark enough so you can compare it to the one on the other side. I could potentially forsee an option where you could "show all inherited" methods on both sides to check how close objects are (in this case, probably up to the point where the inheritance trees unite - for many thats object). Another interesting (though experiment) option is to also show overriden methods and make space for things to keep lining up. Not totally sure on this - but thinking it might reveal accidental overrides or expose smells (again - just thinking aloud though). There's lots of interesting room to explore things in this tool, Tim p.s. Agree on the scroll behaviour and also the jump to next.

Re: [ANN] class-diff: a new tool for comparing classes

by Richard O'Keefe

OK, so I tried Class-diff in Pharo 11. I noticed two issues. (1) I expected it to work like kdiff3, where scrolling scrolls both panes. I'm so used to flying around differences using Next/Previous/Last/First Difference buttons that I do very little scrolling in kdiff3, but when I do scroll, it does its best to keep the two panes aligned. (2) Comparing Array and String, I eventually figured out that I was being shown selectors *defined* in each class, but no selectors *inherited* by a class. For example, String canUnderstand: #asArray but inherits it, so it's not shown in the String pain, while Array defines it. This *looks* like a "one class has it and the other lacks it" case but it's *actually" a "both classes have it and it's different in each", so a difference I'd really like to see. I tracked this down to self aligner align: self sourceClass selectors sort with: self targetClass selectors sort. in updateAlignment, Changing that to self aligner align: self sourceClass allSelectors asArray sort with: self targetClass allSelectors asArray sort got me closer to what I wanted, but then accessing the source code of inherited methods didn't work because inherited methods, by definition, aren't in the class's own method dictionary. I could work around that too, but it's 1:19 AM where I am. In fact that's not quite what I want anyway. I don't want to be shown methods inherited by *both* classes from Object (although methods inherited from Object by one class and redefined or inherited from another class by the other are ones I do want to see).

Re: [ANN] class-diff: a new tool for comparing classes

by Richard O'Keefe

Thanks for the advice about Spec2. I was keen to try Class-diff out, so I fired up Pharo, followed the installation instructions with no problems, and then tried the example. The example got a run-time error, and I expect that it's because the Pharo release I fired up was Pharo 9. Which release(s) of Pharo is Class-diff intended to work with?

Hi Tim, I know Guille has been working with Metacello issues, but I don't know if specifically on this. But for me, it is correct that by default package loading is not logged by Epicea.

Thanks for your nice feedback Richard, I will sketch something and see how it goes. About learning Spec2, for me, the best resource is to directly use the image examples.

Re: [ANN] class-diff: a new tool for comparing classes

by Richard O'Keefe

That's a very nice tool. There are two tweaks I'd like to see. Two classes having methods with the same *name* isn't the same as two classes having the same *method*. When the two classes have a method with the same name, there are at least three possibilities: - The methods are the same method - The methods are different, but the name is defined in some common superclass, so they had better be related methods. - The methods are completely unrelated, like #next in ReadStream and LIFOQueue. The third case applies to every method. Perhaps the best way therefore is to show something in the header, like (score) diff of descendants of <nearest common superclass> <column> <column> The first and second cases are the ones I want to tell apart so that I don't spend any time looking for differences that aren't there. What's the best way to learn how to use Spec2?

Re: [ANN] class-diff: a new tool for comparing classes

by Tim Mackinnon

This looks interesting, and I will definitely check it out. As a small side query - i've noticed a few times now that people are giving load instructions like : EpMonitor disableDuring: [ Metacello new I understand that this de-clutters the work history, so its much easier track real changes - however why isn't there an extension on Metacello in Pharo, that does this automatically - e.g. #loadWithoutLogging ? Then everyones instructions could be much cleaner - and this extension might also do something clever to log that you loaded a baseline - but not show all the code loaded? I'm curuious on this - and possibly its PR we should submit?
