Learn Pharo - Not Working
Hi, everyone. I'm an absolute newbie to Pharo, and to Smalltalk, and I'm trying to learn. I just installed Pharo 7.0.1 (on Windows 10) and I immediately got stuck. I selected "Learn Pharo" in the outline, and it gave me a screen saying: You can learn Pharo by clicking on the following expression: ProfStef go. I clicked on ProfStef go and nothing happened. There are three URL links on the same page that work like they're supposed to, but no matter how many times I try, clicking on ProfStef go appears to do nothing at all. Am I misunderstanding what I'm supposed to do or what's supposed to happen? Thanks a lot for your help. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
Did you use the 32-bit version or the 64-bit version? I just used Pharo Launcher to start a 32-bit image. I clicked on âProfStef goâ and got a separate window with the tutorial. I didnât try the 64-bit version; itâs still beta software. /*âââââââââââââââââ-*/ Sent from my iPhone https://boincstats.com/signature/-1/user/51616339056/sig.png See https://objectnets.net and https://objectnets.org

Thanks, John. It is the 64-bit version. I didn't know it was beta software. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Thanks again, John. I went to the download site and discovered that both 7.0 versions are labeled development versions. I downloaded and ran the 32-bit version. It works fine. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
I think they call the 64-bit stuff âexperimentalâ so it best to learn on the 32-bit stuff. Then you can help the developers debug the 64-bit stuff. /*âââââââââââââââââ-*/ Sent from my iPhone https://boincstats.com/signature/-1/user/51616339056/sig.png See https://objectnets.net and https://objectnets.org

For me it works, but what you can also try is: 1) Click the menu Tools -> Playground 2) Type: ProfStef go. 3) Right click what you just typed and click "Do It" BTW, I'm also new with Pharo (not with programming) and I really enjoy the book at http://books.pharo.org/pharo-by-example/.

Hi Richard, Like you, I have a programming background, but Pharo and Smalltalk are quite a new experience. I downloaded /Pharo By Example/ but haven't gotten around to reading any of it yet. Thank you for the Playground suggestion! That's a great idea, and it works really well. That means I should be able to go back to the 64-bit version. Can you tell me why you don't have to select "ProfStef go." before right clicking it. I had gotten the impression that to execute any Smalltalk statement you always have to select it first.

I believe the default is to evaluate the whole line where the cursor is if nothing is selected. ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

That reminds me - while I fixed the senders/implementers search commands to intelligently look for the nearest selector to the cursor (in pharo7), I forgot about workspace evaluation - doit or printit should find the nearest complete expression (even if multiline) and evaluate that - unless you specifically highlight something. It makes it much more efficient to then examine things quickly. Tim

In general you are correct, but newcomers are more familiar with a click paradigm that a select &doIt paradigm so this specific case is different. In the interest of teaching how to fish :), here is how you can discover these sorts of answers for yourself... Tools > Finder > Source then search for... ProfStef go and you'll see...

Thank you. That's really helpful! Keith

I just checked, the "right click -> do it" only works if at least the cursor is somewhere on the statement. I normally do a cmd-D (macOS) in these situations though. But AFAIK itâs not necessary to select the whole statement. If the cursor is somewhere else in the editor the âright click -> do itâ does not work as expected. I think the editor should maybe put the cursor in the position where you right click. But that is more of a preference. I think if you get used to that behaviour then you probably donât even think about it.
Coming from most common coding editors, I find the editors in Pharo a bit quirky. But I (we?) probably get used to it. I did check online how some people use external editors and I think itâs not worth the hassle. Itâs not as straightforward programming as Iâm used to. And, I think if you use an external editor you miss the âimmersionâ of the environment. Thanks, Richard!
Hi, I want to come back to the original issue reported. To be clear, you report that in the following screen: Clicking on the blue links like http://mooc.pharo.org or http://books.pharo.org works, but clicking the purple 'ProfStef do.' does not ? That would be very surprising, as internally, I think the mechanism behind the handling of the mouse click in the text and then doing something is the same. It would also be quite surprising if this depended on the 32/64 bits difference. In any case it works for me (macOS 64 bit): it opens a window titled 'Welcome (1/29)' containing step one of the tutorial: === "Hello! I'm Professor Stef. You must want me to help you learn Pharo. So let's go to the first lesson. Select the text below, right-click and choose 'Do it'" ProfStef next. === You are on Windows, are there any other Windows users that can confirm this either way ?

Thanks, everyone. I think I owe you all an apology. I just tried the 64-bit version again and it worked perfectly. The instructions just say, "You can learn Pharo by clicking on the following expression:". I didn't expect a new window to open; I had just finished a different Pharo course in which everything stayed in the same window. You'd think I would see a new window opening anyway, but I'm wondering if it might have been hidden behind the main window. I just discovered the window tabs at the bottom as well, which would have helped if I'd thought to look there. Hope I didn't cause anyone a lot of frustration. In a way, I am glad I posed the question, because I have learned a lot in the ensuing discussion. I'll respond to a couple of the new replies, but thank you, everyone, very, very much.

Its exactly this sort of little niggle that adepts just fly by without noticing. Fresh eyes are really important. I just discovered the window tabs
at the bottom as well, which would have helped if I'd thought to look there.

How would you feel about stretching that learning to submit a PR updating that text to indicate a window will open? cheers -ben

On a Win 10 Lenovo laptop with a trackpad with no mouse buttons, the 64-bit version took several clicks on âProfStef goâ to register. I suspect it might be the trackpad which isnât sending mouse messages correctly because I also have problems with other apps. /*âââââââââââââââââ-*/ Sent from my iPhone https://boincstats.com/signature/-1/user/51616339056/sig.png See https://objectnets.net and https://objectnets.org
