creating a subclass in system browser
Hi is there a way I can create a subclass when I have selected a class in the System Browser class list (top 2nd panel). Couldnt see any option - Or is it that no such feature is needed ----- cheers, Sanjay -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
It's already available. On Apr 27 2021, at 1:03 pm, Sanjay Minni <sm@planage.com> wrote:

Thanks Sorry I missed it. (I did not expect it in refactorings) Noury Bouraqadi-2 wrote

I'm not surprised you missed it. I think it's not very intuitive having it on the refactoring sub-menu - especially when you already have "new class" on the right click menu when you select a class. Why not have "create subclass" there as well? By the way, did you have trouble working out the "normal" way of creating a subclass? You select the class definition tab in the browser bottom panel and press the + (plus) button. It took me ages and ages to work that out. Am I just slow or is that also counter-intuitive? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
No, I was not aware of the "+" in class definition tab. actually it's not there (yet) in Pharo 9 Win 64 which I am using. On Tue, 27 Apr 2021 at 18:13, kmo <voxkmp@gmail.com> wrote:

Now I'm wondering if I'm doing something wrong, or short-circuiting the correct approach... When I want to subclass - I simply select the class, and update the class definition page - moving the subclass name (which is the current class) to the class section, and replacing the subclass name with my new subclass name. I can also take care of instance and class variables I need... just save and everything seems to work just fine. Is there a reason to need to do this with a menu? Many times with menu options I'm unclear WHAT it's operating ON :) Nice to know there are multiple ways to get things done in Pharo!! On Tue, Apr 27, 2021 at 8:43 AM kmo <voxkmp@gmail.com> wrote:

Doing it by hand is fiddly and error-prone. I know - because that's the way I used to do it before I realised that the plus button at the top of the browser bottom panel did it for me. (I had no idea that there was also a menu option on the refactorings menu). I think you might find the button to be the better way - I did. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
Can you send a screenshot of the plus button? I'm using v9 on MacOS and I don't see a class + button... On Tue, Apr 27, 2021 at 9:47 AM kmo <voxkmp@gmail.com> wrote:

Don't think it's there in v9. Check in v8 On Tue, 27 Apr, 2021, 7:50 pm Russ Whaley, <whaley.russ@gmail.com> wrote:

Thanks Sanjay... I don't use v8. I'm heavily invested in Spec2 and, well, my apps won't run in v8 :) On Tue, Apr 27, 2021 at 11:15 AM Sanjay Minni <sm@planage.com> wrote:

This shows the browser button for a subclass on Pharo 9 on Linux (not the very latest Version 9 by the way). It only appears when you have the class definition tab selected. I hope this shows up - I posted it earlier but it just hasn't appeared in the list - so I'm posting it again. With my luck it will probably appear twice now. <http://forum.world.st/file/t368903/subclassbutton.png> -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
I hadn't actually noticed the "+" sign but it was there in V7 and is there in V9 on Windows. On Wed, 28 Apr 2021 at 03:15, Sanjay Minni <sm@planage.com> wrote:

I've attached a screenshot. The button appears when you select the class definition tab in the browser. Press it and you get a dialog to enter a subclass name then the text <http://forum.world.st/file/t368903/subclassbutton.png> template for that subclass appears in the browser class definition tab. This is from Pharo 9 on Linux (this is an older version 9 - not the very latest) -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
Ah, in my v9 version, I see a red circled exclamation point (hovering says 'Refactorings' - which has a menu for the +New subclass. Good to know! Thanks! On Tue, Apr 27, 2021 at 12:17 PM kmo <voxkmp@gmail.com> wrote:

It's been there as a refactoring for a while. Why a refactoring? Who knows... Esteban A. Maringolo On Tue, Apr 27, 2021 at 1:59 PM kmo <voxkmp@gmail.com> wrote:

One thing I find challenging when teaching Pharo to new students -- especially those accustomed to IDEs with files, which is pretty much all of them ;) -- is that there are *sometimes* menus (depending on the Pharo version) to add a new package, new class, new protocol, but not a new method, etc. For onboarding new users, I think it's important that these things be intuitive and consistent, especially since updating tutorials takes time. They are super important because inconsistencies become barriers to onboarding new people. My point here is not that a menu option necessarily exists, but that we have a consistent way to explain how to create things even when Pharo changes. Apple used to have 10 commandments for keyboard shortcuts, and I think a similar idea could apply to having consistency in these elements of Pharo.
