agree, a list of the variables and so on is very useful to have, in particular
when "playing" with unfamiliar (someone else's :-)) code.

I don't know MacOS, do you have/use the 'less' and 'vim' programs ?  both can
use  "tags" files created by 'ctags'.  that program, patched[*], can give you
variables, and usage; for instance below the first few lines output based on one
of your scenes (Oct 31st 2023):

$ ectags --sdl-kinds=v -ux pursuitcurve.pov
displayAxis      variable     33 pursuitcurve.pov #declare displayAxis = false;
displayPlane     variable     34 pursuitcurve.pov #declare displayPlane = false;
AxisLen          variable     37 pursuitcurve.pov #declare AxisLen = 16;
Scale            variable     39 pursuitcurve.pov #declare Scale =
AxisLen/image_width;
C                variable    115 pursuitcurve.pov #local C =
_Brightness*_Saturation;
X                variable    116 pursuitcurve.pov #local X = C - (1 -
abs(mod(_Hue/60,2) - 1));
m                variable    117 pursuitcurve.pov #local m = _Brightness-C;
....

only requesting variables, the '-ux' selects an unsorted cross-reference format
to console/terminal; when invoked without options, it'll write a "tags" file.

A yes, the script uses the "File::Basename" module, which is not present 
in your system. I use cpan to install/manage modules. More infos here : 
<https://wiki.debian.org/PerlFAQ> :.

cpan
install File::Basename




more ambitious : yes, lines numbers, list of vars and where vars are 
used. but it's a wip...

looked but cannot, of course, now find the reference. :-)  LeForgeron (I think)
posted an image / chart depicting his setup.  I use the below in my '~/.vimrc',
which is based on / derived from that "tip".  my "workflow" when writing scene
code is to occasionally do a ":make" to confirm there are no typos etc, ie am at
that point only interested in the parsing; for that I have a dedicated
"one-liner" shell script, "povparse", also below.  workflows are v individual,
but LeForgeron's "method" works for me.

way more ambitious though, line numbers ! :-).  I don't "speak" perl, and ran
into trouble when i tried the script (for which thanks) on a Debian VM; attached
a screenshot.

Thank you. I spent some time refactoring the code to get the macros in 
sections in the main include file so I could sort of trace what is going 
on in the whole process.

I'm probably committing the sin of overgeneralizing the code right now 
because I want to also try this with hexagons and eventually cubes.

I'm surprised anyone remembers that project. I found the original html 
and it still had the webring links in.

All that's left is on my homepage: https://joshuarenglish.com/povray/
