Hi All,
I'm rewriting the parser for my pov2mesh application
(http://www.geocities.com/psenzee/pov2mesh/) and I've got a question about
how directives are handled in pov. Are the directives in POV a logically
separate phase like a C preprocessor?
In the pov bnf, things like
#if ( BOOL ) TOKENS ...
lead me to believe that it's a separate phase, but then there are other
restrictions on when and where certain directives can be used that are not
consistent with a separate 'preprocessor'. Any info about this would be
great!
Thanks!

Sadly, no. They sit slightly "below" the parser, closer to the tokenizing
code, yet they do interact with the parser in some complex ways that won't
be clear from the source code immediately.

Is there a document available that shows the definition of the POV-SDL
in BNF? I once updated the syntax highlightning plug-in for jEdit and at
some points I was in trouble, because I didn't know how the POV-SDL is
structured.
Thanks,
Bonsai

Hi Bonsai,
You can find the language spec at
