Re: [Pharo-dev] Having comments for pragma?

Let me try, this is tricky for me as I'm not good at explaining :-) The problems pop out when one need to load the code back. If <coolish: 100> gets parsed and stored in an annotation container as instance of class Coolish (at compilation time), this means that you just introduced a dependency from package of the method which contains the annotation to the package of Coolish class. This is not (or rather was not in my case) desirable, because I need/want to annotate methods in kernel with annotations for tools. Kernel should not depend or tools - I believe we agree on that :-) Note, that this is less of a problem for Java since Java loads all code lazily, on demand and in a defined way. I personally found it very nice - though it has some (solvable?) issues when this lazy loading is used in Smalltalkish environment such as STX:LIBJAVA) You can indeed parse them and store them as raw data and convert them on demand in reflective API. Then, if the class is not available what to do? Return an instance of generic Pragma? Throw an error? When one starts to put an arbitrary code into the annotation object itself it's either processing code only access data or it somehow fiddles about the annotation itself and/or (worse!) about the method itself. The latter results in difficult to debug problems as the time the code is executed is undefined (if you use lazy instantiation to avoid dependency problem). This may be fine with most Smalltalkers as there are other pieces of code that execute randomly in an undefined order and still very few complain :-) but I did not want to make things even worse. For the former, mere data-accessing processing code, I don't see much of a difference by putting it somwhere else. Follows the same logic as visitor, instead of putting code to nodes, you put them to extra visitor class. Eliot's design elegantly avoid these problems (the same way Java does :-) by simply having one defined structure which keeps the logical type of the annotation as data (the selector of the message send). It has other problems, but not the one above. Not sure if it makes sense, but I did my best :-) I'm not saying it's not solvable and you cannot have class per annotation type, but it is not **that** easy to get it right. This is my experience over the years.

Pharo Sprint Friday, 29 July

by Marcus Denker

We will organize a Pharo sprint / Moose dojo Friday, 29 July, starting at 10:00am. (Local Time Paris/Berlin/â¦.). Remotely, you can join us on Slack or the IRC channel #pharo on irc.freenode.net <http://irc.freenode.net/> server. During the sprint, we will try to synchronize local and remote Pharo sprinters. Locally, there will be: - Inria Lille, Building B, third floor (RMoD offices). (As the building is not open to the public, please contact us before in case of visiting) - Santiago de Chile (starting a bit later due to time-zone). DCC University of Chile. Marcus
