When working with Parse_String from strings.inc I noticed that you
cannot use it to create multiple macros on the fly. This is because the
macro overwrites the file it parses from every time, and so the filename
for each macro (which is saved internally IIRC) is the same. The errors
you'll get are a bit confusing, though :)
It's of course no problem to get around this:
<POV>
//parse string macro which parses each time from a different file
#declare so_ParseStringCount = 0;
#macro so_ParseString(S)
#local Filename =
concat("so_parsestring",str(so_ParseStringCount,0,0),".tmp");
#fopen PARSEFILE Filename write
#write(PARSEFILE,S)
#fclose PARSEFILE
#include Filename
#declare so_ParseStringCount = so_ParseStringCount + 1;
#end
</POV>
I just thought I'd post this workaround in case somebody else is having
similar problems. Perhaps I'd would be a good idea to add a note to the
documentation, too, saying that you can't use it to create multiple
macros on the fly.
BTW: Seems one can't live without Parse_String when it comes to create
stuff in POV for which the SDL was not made/intended. I love it :)
Happy POVing,
Florian
