[GemStone-Smalltalk] XML Parser Class/Classes in Gs?

Sun May 7 19:17:27 PDT 2023

Hold the phone :( ... I didn't `set inputpauseonerror on` when I loaded the
files, so I didn't see the compile errors when undefined globals were
referenced ... so the porting effort will not be "greatly simplified" ...

Sooo, the first order of business is to get a picture of the undefined
globals and the best way to do that is to add an additional .gs file first
in line, where you simply define the missing global in UserGlobals just to
satisfy the compiler and then send me the list of missing classes/globals
and I can give you some pointers on the best way to replace the references
... I was actually going to do that earlier today when I mistakenly ignored
the errors ...

I've done a little bit more work. I defined a Smalltalk class with a couple
of methods and got to the point where the initialize methods are being run;
defined CharacterCollection class>>lf and then hit a reference to
RBParser...

I've noticed/realized that all of the classes are being loaded into
UserGlobals by default and having to get through the initialize methods in
each .gs file may not be ideal ...  so at this point I can offer to
regenerate the .gs files using a different dictionary (Globals or ???) for
the class definitions ... and it probably makes sense to edit the .gs files
and move the initialize methods to a final .gs file that is input after all
of the classes and methods have been loaded ... this will allow you to get
a handle on all of the globals needed and better scope out what needs to be
done, rather than dealing with getting initialize methods to run cleanly
(something that could/should be done after all the globals have been
defined) ...

RBParser can be found in the rb project[1], however in the one instance I
saw, the RBParser is being used to parse a Smalltalk method and in this
case it is probably overkill to port the entire RBParser project when all
that needs to be done is parse a method ... there are a couple of different
things that can be done directly in GemStone to satisfy those needs ... So
at the end of the day, it's probably worth deferring the port/replace
decision until later when we know whether RBParser is being used in other
parts of the XML code base ...

Anyway, let me know if you'd like me to regenerate the .gs files using a
different symbol dictionary ... and sorry for the overly optimistic email
...
