[Cuis-dev] [help] Debugging Morph failures

[Hernan Wilkinson]

Juan is the best one to answer this question (he's on vacation for a couple
of weeks).
It is not easy to debug Morph because of the meta-circularity of it that
you already know...
I know that Juan uses the logs that are saved when an error occurs (that is
disabled in CuisUniversity just in case you are using it, there is a
preference to enable it).
It would be great to find a way to break the circularity when doing this
kind of thing. For example, if you want to make changes in the debugger,
the best way to do it is to subclass it, work in the subclass so if an
error occurs the original debugger appears, and when finish push up the
changes to the debugger class, but I do not see how to do something similar
in Morph... maybe creating a new world with a different hierarchy of morphs
that are the one you are working on?... or try to use a "stack of the morph
framework" in the same way some people work with a stack of compiler when
working with meta-circular languages?...
I'm sorry I can not provide concrete solutions but just some ideas...
