Re: [Pharo-users] [squeak-dev] ESUG Squeak DCI image posted

by Trygve Reenskaug

(Copy of post on Squeak list) Hi Hannes, There were no PowerPoint slides. A last minute change to the talk was to move the slides to persistent workspaces in the demo image. This change was not captured in the image I posted before going to Cambridge. The post is now updated: fulloo.info/Downloads/BabyIDE-3a.zip The first slide is the top of the PersistentWorkspace named 'Introduction'. The second slide is at the bottom of that workspace. The demo program is in the colored window. There are 3 yellowbutton commands (use cases) 'animate shapes' - objects come and go 'animate roles' - animates the message flows of the repeated execution of some use case. All flows have the same topology. ALT-1 traces object ids. ALT-2 adds class names . ALT-3 adds role names. 'animate chaos arrows' animates message flows with no common topology. DCI has nothing to offer for such executions. TheWorldMenu>>open...>>BB5BankTransfer runs a very simple demo of the DCI concepts. (Transfer money from one bank account to another.) TheWorldMenu>>open...>>BabyIDE1>>BB5Bank opens a DCI browser on the same example. (Recommended as a first study.) enjoy --Trygve On 29.08.2014 06:32, H.

[ANN]: Flickr API Wrapper

Re: [Pharo-users] Persistence on Moose browsers, showing always a selection in trees and making tree labels editable.

I am not sure I understand, but I assume you want to be able to write another language inside a String constant. STON uses the same escape sequences as JSON. So that means you have to use either the general \uFFFF or a couple of shortcuts, like \' and \". Note however that you can use both single and double quote as string delimiters. So you do: 'x:="foo"' or "x:='foo'" as well as 'x:=\'foo\'' and "x:=\"foo\"" Does that help ? Sven

Re: [Pharo-users] Installing STON from a playground/workspace

by Sven Van Caekenberghe

Offray, I am glad you like STON. It is best to use a Metacello configuration, if there is one. Then, the load script would be: Gofer it smalltalkhubUser: 'SvenVanCaekenberghe' project: 'STON'; configuration; loadStable. STON lives both in StHub and on SS3, so alternatively you can do: Gofer it url: 'http://ss3.gemstone.com/ss/STON'; configuration; loadStable.

Installing STON from a playground/workspace

by Offray Vladimir Luna CÃ¡rdenas

Hi, Last night I was playing with STON for a while. There is still things to learn (and I have already made my questions in the proper thread) but so far I have really like it. I installed it from Configuration Browser, but I would like to install it from a playground/workspace. I know where is located at SmalltalkHub and I can see there the Monticello registration, but in the chapter about Monticello this seems to be used for source control with graphical tools. How can I install STON from a playground/workspace instead of using graphical tools like Monticello or Configuration Browser? How can I know this from the SmalltalkHub page? Thanks Offray

ah nice then you already a contributor and you dont need permission to add to updated pbe repo. thank you for the kind words, when I started making them I had some doubts about how good they will be so I am very glad that people find them useful and that motivates me to keep making them. The video tutorials will continue non stop and soon as I finish with the core of pharo I would like to dive into Morphic.
