Chronos Manager Singleton
by Sean P. DeNigris Feb. 5, 2017

Feb. 5, 2017

Shouldn't the following be lazily initialized? ChronosManager class>>#open ChronosInstance := self new. ^ChronosInstance Right now the singleton gets wiped out every time "open" is clicked in the world menu, and one has to recustomize e.g. time and break limits... ----- Cheers, Sean -- View this message in context: http://forum.world.st/Chronos-Manager-Singleton-tp4933020.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

loading Icerberg repo with dependencies
by Peter Uhnak Feb. 5, 2017

Feb. 5, 2017

Hi, I finally started to move to Pharo 6, so now I can play with Icerberg... my question is: how can I load a repository with all its dependencies? In other words... can I tell Icerberg that for the given Ice Repository to execute BaselineOf? Or is the use case: 1. use metacello to load project (with all dependencies) 2. add all Ice repositories 3. load all code again (this tima via Iceberg) 4. (optionally) remove all previous metacello repositories to avoid confusion Thanks, Peter

Discord now offers search
by Dimitris Chloupis Feb. 4, 2017

Feb. 4, 2017

One of the things missing from our Discord online chat channel to make it as good as Slack was the very valuable search feature which was added this week by the Discord team. So now with Discord we have similar features to Slack, voice chat, unlimited amount of message while slack limits them to 10k and a search feature.

method names - grey or black
by sheridan＠sheridan-mahoney.com Feb. 3, 2017

Feb. 3, 2017

Hi there, While looking at the String class methods, I noticed that some methods are in grey, and the protocol pane indicates that the method belongs to a different package (I think). How is this implemented? I'm curious how the System browser knows how to display the methods this way... Many thanks, Sheridan

self in Nautilus
by Siemen Baader Feb. 2, 2017

Feb. 2, 2017

Hi all, in Nautilus, `self` is always the current class instance. This is great for coding class side methods because we can test code fragments live in the editor, but for instance side methods I have not seen the usefulness of it. At times it can even be confusing and cause errors since a "print it" of it looks quite like an instance (`a Listener` vs `Listener`). Is there a rationale why `self` in instance view does not raise an error or is nil? And, more importantly, could there be a way to set it to a specific value (= can we browse a class with self bound to an specific instance). This would resemble programming in the debugger, but provide the overview that a class browser provides. cheers, Siemen

Pharo 6 and Seaside
by olivier auverlot Feb. 2, 2017

Feb. 2, 2017

Hi, I try to install Seaside on Pharo 6 but the installation procedures fail. If I use the Catalog Browser and I choose to install the stable version of Seaside3, I get a error message but no description of the problem. The installation is simply not possible. If I use the method described on the Seaside website: Gofer new url:'http://www.smalltalkhub.com/mc/Seaside/MetacelloConfigurations/main '; package: 'ConfigurationOfSeaside3'; load. ((Smalltalk at: #ConfigurationOfSeaside3) project version: #stable) load. Seaside seems installed but I can't launch the Seaside Control Panel. I get the error message "KeyNotFound: key #NewListModel not found in SystemDictionary". If I try to install all the Seaside packages: Gofer new url:'http://www.smalltalkhub.com/mc/Seaside/MetacelloConfigurations/main '; package: 'ConfigurationOfSeaside3'; load. ((Smalltalk at: #ConfigurationOfSeaside3) project version: #stable) load: 'CI'. I get the error message "Could not resolve: Zinc-Seaside". Someone have a method to install Seaside in Pharo 6 ? Best regards Olivier :)

[Voyage] Accessing ObjectID(_id) when retrieving objects.
by sergio ruiz Feb. 1, 2017

Feb. 1, 2017

Hi, all.. I am working on a Teapot REST interface, and am getting ready to implement the create, read, and update methods for the objects, and I need a way to refer to the objects. I figured that since Voyage was already creating _id through MongoDB, I could just pass that on when I retrieved that object, but I donât see how to do that. Is this possible? Would I need to create my own numerical indexes to my objects and just retrieve them as part of the object query? Thanks! ---- peace, sergio photographer, journalist, visionary Public Key:Â http://bit.ly/29z9fG0 #BitMessageÂ BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.Village-Buzz.com http://www.ThoseOptimizeGuys.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Phobos and printing
by Hilaire Feb. 1, 2017

Feb. 1, 2017

Hi Pavel, Is there a way to ask a PhobosHTMLCanvas instance to print an html file. I have html files built from Mustache templates and I try to send it to the print dialog via Phobos. So far I send an entire locale html file content via #rawXML: message, but I got mix results, the style does not seem to be taken in consideration. Thanks Hilaire -- Dr. Geo http://drgeo.eu

Re: [Pharo-users] How to view hierarchy of multiple classes in a package?

Changing ClassWidget>>#showHierarchy to: showHierarchy: aBoolean | all | (showHierarchy := aBoolean) ifFalse: [ ^ self ]. all := IdentitySet new. model selectedPackageGroup asNautilusSelection classes do: [ :cls | all addAll: cls allSuperclasses; addAll: cls withAllSubclasses ]. self cachedHierarchy: (SortHierarchically buildHierarchyForClasses: all) Will make the hierarchy button show the tree for all classes in that package/tag.

This seems to have generated a bit of conversation which has helped me quite a bit. Denis, your picture has made me realise that the System browser is a bit better than I realised. However the example I was looking at was a package that had a series of Announcement subclasses, AND what wasn't obvious was that they were all subclasses of the same parent "Announcement", as that isn't shown - you just get a series of classes not rooted under some parent (even if it was object). I'm guessing that just things that are subclasses of each other in the same package are shown? I was hoping that pane might show - Announcement + A + B + C I'm now wondering what it will show if you had a few different subclasses of the different collection classes (ok it's a bad idea to subclass them, but my point is if you had a few models at different points in a hierarchy)? I'm guessing you would see the same flat list - but I will go and try that to help me learn a bit more. Tim
