cmd +W the problem is that using shift make the short cut difficult to do. I have a lot of problem with cmd-b+cmd-N It does not work with me 50% of the time.

Re: [Pharo-users] How do i list the execution order of statements inside a method?

by Mircea SamoilÄ

Thank you for taking the time to explain this in such technical detail. I reread my answer to the example StÃ©phane Ducasse gave me, and i realize some of you might have gotten the impression in never fully understood the code and what i meant. I may lack the technical background to express this, but i did fully figure out what it meant and how it would help me. Gathered more "intel" form other sources. "Check out our AST interpreter that will give you fine-grained control over the execution of Smalltalk code. With underlying AST as execution format it is very easy to map the currently executed code back to the source code." http://smalltalkhub.com/#!/~dh83/ast-interpreter The keywords contained in the answer have indeed assured me that in am indeed looking into the direction. I've since compiled a list of all the things i am supposed to know before i can attack the problem myself, and happily started my journey to knowledge. Conceptually i think i have the solution, as all the pieces seem to be available, but i think it will take some time before i slowly transition this mental model to a "working" model, given my lack of practical expertise. I have high hopes that what i'm trying to achieve will also help alleviate some of the caveats OO has now, a rather opaqueness of objects, a "hiding" of relevant information behind something else, and the need to "know" the model of all the separate packages involved, but which you don't actually need to build something rather small in between. I find it rather peculiar that it is in this field also, the best advice of how to fix things comes from people complaining. I found this http://blog.jot.fm/2010/08/26/ten-things-i-hate-about-object-oriented-progr… I may not share the expertise of the writer but i can say, with confidence, that i am quite familiar with the feeling.

Re: [Pharo-users] Getting started with Gemstone for Pharo users

by Martin Dias

If there is an inter-dialect serializer for Pharo and Gemstone, then you should iterate over all your fuel files migrating one by one. In fact, fuel was designed for speed and precision for recreating any object rather than inter-dialect compatibility. So, at least for the moment, it is out of scope. Good luck!
