At the moment, I'm quite interested to be able to do Process Mining: http://www.processmining.org/ The idea is to be able to extract from logs a process. I have already done some experiments some time ago. I'm using a basic alpha algorithm and build a Petri net that represent the process: https://www.youtube.com/watch?v=wdf80t32v-0 The repo is here: http://smalltalkhub.com/#!/~SergeStinckwich/Moose-XES Maybe I can use your Petri Nets viz instead of mine. How I can load your P/N viz code in my image ? Regards -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/

Because the idea of Ghost was mostly the design, not the code itself. The code was very very little. So in Marea proxies you can see how I: 1) Created a few different proxies for different purposes. For example, I created special proxies for classes and metaclasses. And each of them implements custom messages to avoid unnecessary interception (for example, MARMetaclassProxy implements #isMeta answering true. Both, proxy for Class and Metaclass implement: isKindOf: aClass ^ (aClass == Class) ifTrue: [ true ] ifFalse: [ super isKindOf: aClass ] "would be intercepted" and so on.... So basically....you are able to implement custom proxies and implement custom messages so that you avoid intercepting them. 2) In Marea, I have multiple proxies that store the information differently. So for example, Marea proxies needed a graph id and a "position" (an integer). If both were small enough, I was doing a bitShift and storing them in a super compact proxy class that would have only one small integer. So....what I want to say is that while ghost code is OK, the most interesting usage and development of those proxies is in Marea, in the category 'Marea-Proxies'. > #Luc > > 2015-04-01 8:29 GMT+02:00 stepharo <stepharo(a)free.fr>: > >> Mariano spent a couple of years on it so... >> >> >> >> Le 31/3/15 21:37, Denis Kudriashov a Ã©crit : >> >> Hi >> if you want to build proxy look at Ghost library from Mariano Martinez >> I not know right repository.

" is because thatâs the description of the version (or baseline), not the project description (thatâs the place of #catalogDescription, and thatâs why it is on class side: is more durable). cheers, Esteban" ah ok makes sense now. Will do thanks.

Cool! At the moment I'm searching where to put a description for the projects :) I was asking myself why the link of a project opens a small project description taken from the metacello config instead just opening the project on smalltalkhub.
