Error handling in mondrian

by Alexandre Bergel

Hi! The new version of Mondrian should make some of us happy. Before displaying the view, using the #open method, the view is rendered in a non displayed form. This means that if there is an error in your script, you will have a debugger instead of a freeze of the image. This is something I should have done at least 1 year ago. But at least, now this is done. If you have a scenario that freezes the image, please let me know. This is really annoying. Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

children shape

by Tudor Girba

Hi Alex, I would need your help in introducing the ChildrenShape. Without this, the FormsBuilder is highly underutilized. The problem I have is that currently the drawing of the nested graphs is handled on the Figure side, while it should be handled by the Shape. So, I would need your help to move this behavior while still preserving the caching logic. The ChildrenShape should then override the display:on: to display these elements. Would you have time to look into this? For example, the following code should define a umlClassShape: | builder childrenShape titleShape umlClassShape | childrenShape := MOChildrenShape new. titleShape := MORectangleShape new text: 'Title'; fillColor: Color transparent. builder := MOFormsBuilder new. builder column; center; fill; pref; grow. builder row; center; pref; fill; grow; row; center; fill; pref; grow. builder x: 1 y: 1 add: titleShape. builder x: 1 y: 2 add: childrenShape. umlClassShape := builder asShape. view nodeShape: umlClassShape. view nodes: (1 to: 3) forEach: [:each | view nodes: (1 to: 10) ] Cheers, Doru -- www.tudorgirba.com "Not knowing how to do something is not an argument for how it cannot be done."

Fwd: do you have an idea how we could talk from pharo to vw?

I don't know about any such frameworks, since I never needed one, but I'd be surprised if one for Smalltalk does not exist. ;) > > The only advantage I can immediately see to doing something similar to what I did with STaPLe is that you can eliminate the overhead of process switching and socket communication by running the two virtual machines in the same process. The essence of STaPLe is a small piece of C code that staples together the virtual machines of VisualWorks and SWI-Prolog by using their C foreign function interfaces. But except for the fact that they communicate through these foreign function interfaces and not through sockets, STaPLe does much the same thing as you would have to do for distributed messaging: it converts strings and numbers from one virtual machine to the other, makes proxies for objects so that they can be sent a message from the other side and so on. This creates a lot of overhead for each message send. I am not sure whether process switching and socket communication creates enough additional overhead to try to optimize it away. > > So: Try distributed messaging first. That way you don't need to do anything in C. If you find it is too slow for what you want to do, try to get rid of process switching and socket communication by using the foreign function interface way. If it's still too slow, then err ... I think the only option left is: run all your code in only one Smalltalk virtual machine ;)) > > Regards, > Kris. > > On 05 Aug 2010, at 11:47, Stéphane Ducasse wrote: > >> thanks! >> >> Stef >> >> On Aug 5, 2010, at 11:46 AM, Andy Kellens wrote: >> >>> Stef, >>> >>> I added Kris's new email address to this conversation. >>> >>> On 05 Aug 2010, at 11:45, Stéphane Ducasse wrote: >>> >>>> Hi kris >>>> >>>> how can I access the code of staple? >>>> >>>> Stef >>>> On Aug 5, 2010, at 10:48 AM, Andy Kellens wrote: >>>> >>>>> Hello, >>>>> >>>>> The trick with using VW as a DLL indeed seems a good idea. >>>>> While I also don't have a clue how this actually works, I believe Kris used it when he implemented StaPLe (a bridge between SWI-Prolog and VW). >>>>> You can probably find some example code on that project's website: http://staple.sourceforge.net/ >>>>> >>>>> Andy >>>>> >>>>> On 05 Aug 2010, at 10:42, Johan Brichau wrote: >>>>> >>>>>> Hm.... except the traditional unwanted xml-rpc communication, I would investigate the possibility to use Alien/FFI and talk to Visualworks as a dll. >>>>>> I seem to remember that Visualworks can be used like that, but I'm not sure. >>>>>> >>>>>> If that works, you can create a high-level communication layer that would make communication seamless. > >

MOChildrenShape

by Bergel, Alexandre

Hi Doru, In a form builder, should we have a rendering of the inner nodes at each = occurrence of a children shape? If there is no children shape in a form = builder, can the inner nodes be rendered?

Orion Framework

by Laval Jannik

Hi guys, I publish a small description of Orion on moose website (http://). A tutorial is also available (For now it is small and maybe it has some english issues. I will improve it). Orion is a tool for reengineering, to simulate changes and compare their impact on multiple versions of software source code models. You can try it: ===== Gofer new squeaksource: 'Orion'; package: 'ConfigurationOfOrion'; load. (Smalltalk at: #ConfigurationOfOrion) perform: #loadDefault. ===== I am also available to answer your questions. Cheers, --- Jannik Laval

finder improvements

by Tudor Girba

Hi, I am working a bit on some enhancements for Moose Finder: - You can now extend it with new presentations by adding a method in the Finder with a pragma like: sourceTextIn: aComposite <presentation: 10> aComposite text title: 'Source'; titleIcon: MenuIcons mooseSourceText; display: [ :each | each mooseInterestingEntity sourceText ]; when: [ :input | (input mooseInterestingEntity class canUnderstand: #sourceText) and: [input mooseInterestingEntity sourceText notEmpty ] ] - I added icons for the default presentations (see attached picture) Cheers, Doru -- www.tudorgirba.com "From an abstract enough point of view, any two things are similar."
