Would you please confirm which version of the VM and Pharo you're using? (copy the output of System -> System Reporter default page) Thanks, Alistair

Learn Pharo - Not Working
by magicspeller Feb. 5, 2019

Feb. 5, 2019

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

why doesn't this baseline load any package when included in another baseline?
by PAUL DEBRUICKER Feb. 4, 2019

Feb. 4, 2019

Hi - In this repo MCHttpRepository location: 'http://www.squeaksource.com/TimeZoneDatabase' user: '' password: '' There is the BaselineOfTimeZoneDatabase If in a Pharo7 playground I run Metacello new baseline: 'TimeZoneDatabase'; repository: 'http://www.squeaksource.com/TimeZoneDatabase'; load It loads into the image fine and seems to work. If I include it in another project like this ... spec baseline: 'TimeZoneDatabase' with: [ spec repository: 'http://www.squeaksource.com/TimeZoneDatabase' ]. spec package: 'MyPackage' with:[ spec requires: #('DependencyA' 'DependencyB' 'DependencyC' 'DependencyD' 'TimeZoneDatabase')] spec group:'default' with:'MyPackage'. and load that project into a different, clean Pharo 7 image with Metacello new baseline: 'MyProject'; repository: '/my/pharo/packages/'; load: 'default' Then none of the TimeZoneDatabase packages are loaded and only the postLoadDoIt from the BaselineOfTimeZoneDatabase is called. (The other dependencies aren't loaded either but I figured to just use this TimeZoneDatabase as an example for this email). In the BaselineOfTimeZoneDatabase the #baseline: method is baseline: spec <baseline> spec for: #common do: [ spec postLoadDoIt: #buildSystemDatabase. spec package: 'Time'. spec group: 'Core' with: #('default') ]. spec for: #squeak do: [ spec package: 'TimeZoneDatabase-Squeak' with: [ spec requires: #('Time') ]. spec group: 'default' with: #('TimeZoneDatabase-Squeak') ]. spec for: #pharo do: [ spec package: 'TimeZoneDatabasePharoPreload'; package: 'Time' with: [ spec requires: #('TimeZoneDatabasePharoPreload') ]; package: 'TimeZoneDatabase-Pharo' with: [ spec requires: #('Time') ]. spec group: 'default' with: #('TimeZoneDatabase-Pharo') ] I'm clearly doing something wrong but don't know what. Any ideas on what to change or try next? Thanks Paul

Hi - How can I see who wrote a method and when they wrote it in Calypso? In Nautilus it was the AnnotationPane plugin IIRC. Thanks Paul

Pharo MOOC 7.0 image
by eftomi Feb. 4, 2019

Feb. 4, 2019

Did someone compile a 7.0 MOOC image yet? Seaside is easy to load, however I got stuck with various packages of Bootstrap / Magritte. When I try to load these either through Metacello, Catalog Browser and through Iceberg there's no success. Catalog Browser usually gives an error message in the status area. QCMagritte seems quite useful and is marked as 7.0 compatible in Catalog Browser. The procedure on Github: Metacello new githubUser: 'Afibre' project: 'QCMagritte' commitish: 'master' path: 'src'; baseline: 'QCMagritte'; load. runs ok, however the majority of Seaside tests are then yellow, some red. As you see, I'm mostly interested in web development :-) -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Hi keith did you look at the Pharo mooc? http://mooc.pharo.org <http://mooc.pharo.org/> Because there are many videos explaining interaction. To execute an expression you should either select or if it is on one line you can just use command-D or command-P Stef

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

favorite way to migrate from mczs to git?
by ducasse Feb. 3, 2019

Feb. 3, 2019

Hi Paul When you commit your changes to your fork you can cherry pick what you want to save. On the left you have a item list with tick and you can untick them. Only the selected items will be committed. Let us know if this is not working for you. Stef
