Hi,
i have written a POV 2.2 parser with Lex&Yacc some years ago. You could check
the results at my homepage:
http://ourworld.compuserve.com/homepages/thbaier. It is a pov to mdl (Moray)
convertor.
Please keep in mind: POV 2.2 syntax was a little bit simpler than 3.1.
Anyway, the main problem with L&Y was a shift/reduce problem during comma
parsing.
There a lot of expression you could set a comma but you do not have to.
I would agree a L&Y grammar but the facts stand against it.
Ok there are solutions to get a L&Y grammerand parser, but it has not a high
priority. You have to write a lot of convertor code to translate old 3.1 files
into new. A lot of work.
But if someone has a L&Y grammar + code to translate old 3.1 syntax into new
syntax, no problem we will discuss the solution.
