Hi all,
Currently I am using
\startuniqueMPgraphic{foo} ... if (\DbgFill=0) : fill whatever fi ... \stopuniqueMPgraphic
in my MP graphics. \DbgFill (0|1) is just a trigger, which prevents filling in case of visual debugging. Instead of always writing this 'long' form, it should be possible to use a self written mp-macro instead. But my naive approach
def dbg_fill (expr p) = if (\DbgFill=0) : fill p ; fi enddef ;
doesn't work. I get
DbgFill
! Unknown relation will be considered false.
How do I realize this trigger inside pure MP code and set it outside in TeX? The trigger should be global and can change during runtime. Any help is welcome.
can you make a test file?
