Re: [Pharo-users] Learn Pharo - Not Working

by Sven Van Caekenberghe

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 ?

But why would you arbitrarily highlight a line? I was frustrated that with my cursor on a valid selector (or class, or parameter), selecting the whole line often resulted in an error? Or are you simply suggesting that it should highlight the expression itâs identified before doing the evaluation? I didnât think of that, and itâs a good idea. To be clearer - in a playground if you had: 5 + 4. âHelloâ size + 5 (cursor here) What should meta-p do? I would argue - print 10 not give an error? This feels more in line with power of our tools right? Tim

Don't forget, the dll can be stripped too ! I saved about 10MB on Dr. Geo bundle with Linux and Windows VMs stripped.

Now what frustrates me is that Command-B does not automatically select the line. I always wanted that Command-B looks for implementors when the symbol is not a class (if it is a class we get the class definition) Command-M when the symbol is a class should do a Command-B else a look for implementors I think that now denis reintroduced the behavior I added long time ago and that was removed. The glitch left is the missing automatic selection of the line :) Stef
