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.

Re: Learn Pharo - Not Working

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 ‘ProfStef go’ and got a separate window with the tutorial. I didn’t try the 64-bit version; it’s still beta software.

Thanks, John. It is the 64-bit version. I didn't know it was beta software.

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.

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/.

Cheers,
Richard

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.

Thanks again,
Keith

I think they call the 64-bit stuff “experimental” so it best to learn on the 32-bit stuff. Then you can help the developers debug the 64-bit stuff.

I believe the default is to evaluate the whole line where the cursor is if
nothing is selected.

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.

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 ?

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... WelcomeHelp-class>>learn

which does... (self doItFrom: 'ProfStef go.')

Double-clicking "doItFrom:" selects it, then hitting <Ctrl-M> does "Code search... > implementors of it"

that is commented... [left as an exercise for the reader]

On Win 10 and this works for me in both 32-bit and 64-bit Pharo 7.0.1 (build: 146, commit: c48755a)

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.

Warren

No problem, good luck with your further explorations, welcome to Pharo.

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 it’s not necessary to select the whole statement. If the cursor is somewhere else in the editor the “right click -> do it” 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 don’t 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 it’s not worth the hassle. It’s not as straightforward programming as I’m used to. And, I think if you use an external editor you miss the “immersion” of the environment.
