I'm forwarding this to the list.
Please always reply-all so a copy goes to the list.

More thoughts on converting VFP to Python:
line-by-line can take into account control structures. One just
increases or decreases the indent when encountering the start or end of
a structure.
a bigger challenge is handling the work-area related commands such as
Scan, Replace, Skip, Set Relation, ....
Actually Bob I'm using Dabo which has the above covered. You should take a
close look at Dabo. I am able to do most everything I've ever done in VFP.
I don't use IDE Dabo provides and I'm able to get everything done. At this
point I can almost copy any VFP form.
the concept of data sessions
So far I'm able to read the dbc and have most of what is required for the data
sessions
macro substitution
That looks like a problem for the moment.
all the GUI stuff would be translated to one of the python GUI packages.
Not a trivial task!
So far it has not been to bad. The real issue is converting to sizers. But
the windows side complete.
An outline:
create initial dictionary of all initial special characters, keywords
including their abbreviations, ...?
create dictionary to hold all user-generated names (variables, classes,
procedures, windows, ...?)
awareness while scanning of #define and blocks such as text .. endtext
to ignore
scan file for procedure/function/define
certain initial characters take precedence = ? & # * && @ \
this list may be extended temporarily by commands like text
; is a special final character
assignment statement?
initial word a keyword or function?
if none of the above error?
and on and on.
If I had a decent parser I think the rest would be easy. But I don't and I do
not understand the all the CS stuff.
