Re: [Pharo-project] **IMPORTANT** MUST READ: Pharo Association and Consortium

by Herve Verjus

Hi All, thank you Stef for this piece of information. I will subscribe as individual member. Let's say, you're doing a good job, I enjoy a lot using Pharo, that let's me permit do/use funny and usefull things, teaching students, make some research software prototypes, etc. I have to say I would probably not succeed in convincing my university staff to subscribe to the consortium. I personnaly vote for that, I will try and will do my best but I'am not optimistic :-( I understand that the fees are intended for enterprises or organizations that aim to make business arround and/or with Pharo. I and my lab are not in such a perspective. Maybe I would succeed in convincing IAE director for some hundred euros for supporting your work...not for 1000 or more. Nevertheless, I will try.

It would need some love to make it more usable. In Magritte-XML we took a few side ways. When it comes to descriptions in relationships it is important who is in control of the "real" description of an object. In Magritte-Xml we support two use cases. The default option is to support inheritance. That means if you navigate a relationship each object is asked for its description. This way an object you get can be a subclass of the object you described. The second option I need more often is to inject descriptions into a relationship. Meaning the description of the relationship defines the description for the contained objects. This way I can alter the use of my objects by the way the objects are approached/by use case. This can be done by setting #reference: on your relationship description and by specifying "beDescribedByReference" to the relationship description. Sadly I couldn't come up with a nicer selector :) As an example I use COUserSession>>#userDescription <magritteDescription> ^MAToOneRelationDescription new accessor: #user; label: 'User of App'; classes: (Array with: COUser); beDescribedByReference; reference: (COUser new remoteDescription kind: COUser); beXmlElement; beInlined; priority: 20; yourself Here "remoteDescription" includes a reduced view of the user for remote usage. It contains just two values of the user instead of everything. By additionally defining "beInlined" you can prevent the relationship to create an additional element. Otherwise the relationship would create a xml element and the object as well. While I'm writing this I'm not sure if the setting for kind: is still needed. Nick did something so you don't need to set it like this, I think. I hope he will read this and clarifies the use. Regarding your other mail. I cannot tell much about the option descriptions in Magritte-Xml. I never used them myself and so I'm no expert. Jan could say something about them and IIRC Nick (again) did something with the multiple option description. hope that helps, Norbert

Re: [Pharo-project] Funny example

by Hilaire Fernandes

Indeed. DrGeo is not multithread safe. In this example, the animation is done in a background thread, at the end of the smalltalk code this is the "canvas do: [] loop" code. So when playing interactively with the sketch, changing parameters for example, your are forcing a sketch update, and at this exact same time the animation tread may be in the re-rendering phase. So the artefact you see is because the sampling of the locus is recalculated in one thread and rendered (incomplete) in another thread. We are exploring here the Dr. Geo bounds... I am not sure I want to investigate the case yet.
