I'm thinking of presenting a talk at OSDC on iterative grammar
development by combining Test::More and Parse::RecDescent - in other
words, bottom-up development of P::RD grammars, based on simplistic
application of eXtreme Programmings 'Test-First' idea. I found this to
be extremely powerful for writing a complex data validator (that was
ultimately junked as the client could never decide what was and was not
My problems in writing this are several
1. I am not an expert in grammars - I dont even really know what LR and
LL imply - hence my academic credentials for this most academic of
subjects are shot to pieces
2. Theres a lot of terminology and theory behind P::RD, not all of which
3. I tried once before to write a talk on this, and it was so dry and
dull and long I just gave up...
So if I hear a clamoring of people saying 'personally I stay at home on
Saturday nights, just so as I can polish my P::RD grammar, so your talk
sounds like 45 minutes of bliss', then I'll try again.
