Re: [Pharo-users] NeoJSON and polymorphism

by Sven Van Caekenberghe

Hi Juraj, This would be a simpler form of the type/class tags that are often used in JSON encoding. Since there are many ways to do this, there cannot be one solution. NeoJSON mapping was not designed to cover these cases. Nor is JSON meant to do this. STON is one (rather elegant if I may say so) answer to this problem. Your example would be encoded as [ PngAttachement { #url:'http://example.com/random-name.txt', #fileName:'chapter-one.txt' }, TxtAttachement { #url:'http://example.com/random-name.png', #fileName:'image.png' } ] Still, the question of how to do this kind of dynamic decoding is an interesting challenge.

Re: [Pharo-users] Bloc Space within a Space

Hi sean normally with bloc you should be able to build the expose mode on mac os X. with multiple little worlds showing windows inside and to control all the events. It was the goal of alain now I do not know but it should Stef BlUniverse I am the lowest level in Bloc. My responsibility is to manage the low-level services such as managing windows, event queue and the drawing synchronization. My main responsibility is to manage and to keep in sync the opened Spaces. I am the interface used to create/delete window. To achieve that, i use the notion of Host (see: BlHost). Users can choose a preferable host. In order to do that a universe must be stopped first. Example: universe stop. universe preferableHost: MyHost new. universe start. BLSpaceManager I am a Universe space manager. I contain Bloc spaces, can add or remove them. I am also responsible for sending pulses(tick) messages to spaces I know. I am used by Universe in order to provide support of multiple spaces within the Universe. - addSpace: add a space - removeSpace: remove a given space - clear close all spaces - pulse send pulse message to all spaces One simple example is simply gorgeous.

Hi Stef, since I'm only doing Athens rendering, it might be possible to do a native window implementation. That said, I don't know how to get started with that.
