Hi,

I was wondering if anybody could help me with two basic questions:
1) I really like the coloring in the editor window, but can't seem to turn it on
for a few of my files (I assume its called "Color Syntax Highlighting", but that
option seems to be on everywhere, even in files that only have black&white
text.)
2) Is there the possibility to show the results of functions you use in macro's.
I've made a macro which involves rotating a triangle by the result of the
function (atan2), but it doesn't render as I expected it to. I would like to
see the plain number result of the function, in stead of just the final render,
because there could be numerous reasons why my triangle is not ending up where I
expected it to (for all I know it could be rotating 20 full circles and ending
up in nearly the same position it started in...)


Thanks, Joost

Do the files that are in black and white have a "pov" or "inc" extension?  Search for
"syntax highlighting" in the help file.

Look into the #debug statement.

#debug concat("The value is: ", str(atan2(5), 0, -1), "\n")

                                                          - Warp

Thanks for the quick replies; debug and string was what I was looking for. By
the way, I couldn't get concat to work with the function atan2, but it did work
using the identifier. I figured out the value outcome of atan2 is in radians,
and not in degrees, which clarified my triangle hardly rotating :-)

I had already found syntax highlighting in the help file, but turning it on and
off didn't do anything. But the debug solution is the more important one for
me, because it was stopping my progress.

Thanks, Joost

In the windows version this happens sometimes...
You can turn it on by

Right-click, editor preferences (or alt-enter) |
click the language/tabs tab |
select POV-Ray from the language drop box |
click apply

I saw something like that and thought, I am not typing all that every time I
want to see a val.


#macro echo(Str)
  #if (1)
      #debug Str
  #end
#end
#macro echof(f)
  echo(str(f,2,5))
#end
#macro echov(V)
  echo(concat("<",str(V.x,2,5),",",str(V.y,2,5),",",str(V.z,2,5),">"))
#end
#macro echov2(V)
  echo(concat("<",str(V.x,2,5),",",str(V.y,2,5),">"))
#end

echof(a)
echo("\n") // always follows or delayed in echoing

#macro cr()
  echo("\n")
#end

The language option solved my highlight problems.
Thanks, also for the debug macro!
