Re: [Pharo-project] Announcements for Pharo?

by Janko MivÅ¡ek

I found Vassili's Announcements a really cool way to implement any publish/subscribe event mechanism, because it is generally useful for many things from events in GUI apps to those on web apps and they can be extended even in a distributed way (think Hydra). Announcements in Pharo are therefore very welcome, I'd just be careful that they are API compatible with VisualWorks, to ease porting.

Technically, Dictionaries are collections of Associations. Now, "Smalltalk" has globals *and* classes. Which means, we can do Object := nil. And everthing is dead. This is especially a problem in an ende-user scripting systems (e.g. something more powerful than etoys, but targeted at non-programmers). Sometime in the last century, someone started to work on making Squeak more stable (or secure for some meaning of secure). Now, one can fix the assignment problem in two places: A) name analysis of the compiler. The place where all the other warning are generated. B) replacing the association in the Smalltalk dictionary by one that can not be changed. (here "value:" raises an exception). The isSpecialWriteBinding was the test to check if the binging was read=only or read/write. Some classes where referenced using a read-only binging (those that where very old), but all new classes where referenced using a normal association. There was no code in the image that would create ReadOnlyVariableBindings. It was never used in this century. And: is that really at the right level, that change? For controlling assignments, the compiler's checking phase is much better. If one wants to make the structure of the sytem (the "structural model" in the sense of structural reflection) read-only, this does not help at all. Remember, this hack just touches *one* place in the object graph that starts with "Smalltalk". It does not, for example, secure the method-dictonary. Nor changes to the inhertance hierarchy. This is actually a very cool topic of research... and we are incidentally actually working just now on a paper that shows one cool direction of providing "read only" views on shared object graphs like the one that represents the structure of the system.

It looks like Association>>isSpecialWriteBinding is gone in Pharo. Can someone confirm it? It hurt because it is used by Magma.. -- http://blog.ofset.org/hilaire

I wrote this to be useful for simulations (of hierarchical assemblies), and the UI has a hierarchical structure. Keith

Great, thanks! For which shortcuts does that usually work? cut x copy c paste v undo z open o print p all a save s anything else? Michael
