We have a preliminary parser that uses lex & yacc (I'll forward it to you
off-list since the library is about 400k). I haven't gotten too far with
integrating it yet, mainly because we'll need somewhere to put the data
after we read it from the GEDCOM.
Yeah, the date class isn't the prettiest; it's mostly my fault, but it
seems like you get the idea of where I wanted to go with it. I seem to be
better at writing algorithms and design specs than actual code, mostly
because I'm out of practice. Now that I'm getting the hang of coding on a
large project at work, it's getting a bit easier to read and code.
Did you get a chance to review the proposed DB schema, ERDs and the
comments about them yet? Also, did you get a SourceForge login yet so I
can set you up with write access to CVS?
