Hi,
I tried the "Dcaron" example from the MetaPost manual (page 50) and it
works nicely when called with "mpost".
% Dcaron.mp
fontmapfile"=lm-ec.map";
beginfig(56);
picture q;
path p;
interim ahlength:=12bp;
interim ahangle:=25;
q:= glyph "Dcaron" of "ec-lmr10" scaled .2;
for item within q:
p:= pathpart item;
drawarrow p withcolor(.6,.9,.6) withpen pencircle scaled 1.5;
for j=0 upto length p:
pickup pencircle scaled .7;
draw (point j of p -- precontrol j of p)
dashed evenly withcolor blue;
draw (point j of p -- postcontrol j of p)
dashed evenly withcolor blue;
pickup pencircle scaled 3;
draw precontrol j of p withcolor red;
draw postcontrol j of p withcolor red;
pickup pencircle scaled 2;
draw point j of p withcolor black;
endfor
endfor
endfig;
% -------
But how can I get the glyph path(s) with luatex (mplib)?
Minimal example (glyph.mkiv) and console output are attached (log is
empty). Looks like I can't use 'fontmapfile' and without it the glyphs
are not found.

Forgot to tell why I need the glyph paths...
I implemented multi path support in drops yesterday and now I want to
test it with some glyphs. Currently I use Inkscape (export the glyph
path as PDF) and pdftoedit to finally get a MP path. Time consuming and
the result still needs a manual clean-up.
Here is my current test example. Needless to say, that the path blew up
my code in the first run (a too low threshold value) :-D

Thanks for this nice example (I wasn't aware of this).
But this doesn't really help me with my problem. I guess my example had
too much irritating eye candy, so I made another one :-)
http://www.wuala.com/indiego/public/ConTeXt/pathtest2.pdf
The problem is, that I need direct access to the glyphs path(s), as I
must calculate the offset paths for the sub shadows (umbra/penumbra).
Inkscape has a similar function called "inset/outset path", if I
remember right.
In the example I used a negative offset for the umbra shadow (udistance)
and a positive for the penumbra shadow (pdistance). The original path is
drawn as 'arrowpath'.
The path creating algorithm (based on the Tiller-Hanson alg.) works
quite good so far, but still needs a lot of tweaking. And glyphs have a
wide range of shapes, so they are nearly ideal for testing purposes.
Anyhow, it can't be helped, if 'glyph' is not working. I'll test some
ConTeXt generated PDF glyphs (MPpage) then and see if I can optimize the
manual path creation a little bit.
Best wishes,
Peter
