Since textext() always returns a single picture that can't be decomposed into
smaller building blocks
mkiv3.pdf
Description: Adobe PDF document
Hans suggested to textext() each desired snippet individually. So I tried
---
\setupbodyfont[10pt]
\starttext
\startMPinclusions
pickup pencircle scaled 0.05pt;
defaultpen := savepen;
picture crosshair;
crosshair := image(draw fullcircle scaled 2pt;
draw (0,-2pt)--(0,2pt);
draw (-2pt,0)--(2pt,0);
);
bboxmargin := 0;
\stopMPinclusions
\startMPpage
for item within rawtextext("$(h,g)$"):
draw bbox item withcolor 0.8white;
draw item;
endfor;
draw crosshair;
\stopMPpage
\startMPpage
draw bbox rawtextext("$($") withcolor 0.8white;
draw rawtextext("$($");
draw bbox rawtextext("$h$") withcolor 0.8white;
draw rawtextext("$h$");
draw bbox rawtextext("$,$") withcolor 0.8white;
draw rawtextext("$,$");
draw bbox rawtextext("$g$") withcolor 0.8white;
draw rawtextext("$g$");
draw bbox rawtextext("$)$") withcolor 0.8white;
draw rawtextext("$)$");
draw crosshair;
\stopMPpage
\stoptext

Clearly, this gives me each glyph individually but stacked on top of each
other. What I need though is that the second figure looks exactly like the
first one (with all glyphs in the right location) except that the grey bounding
boxes appear per glyph.
Thanks for your help,

I know what you want now, but I have no idea how to go about doing it via this approach. It could be made to work from the other direction (by writing lua code to intercept tex nodes) but that is not trivial either. You could use standalone metapost with btex ... etex, that would work.

There are two small lua tutorials in the program, and I am looking for input on both. There is one that is supposed to be a general beginner's introduction, and one specifically about fonts. For both, I am looking for input on what subjects I should cover? Since both tutorials will end up as articles/wiki pages, it makes sense to ask everybody on the list for input (but requests by actual attendees will be scored considerably higher). I'm planning to work on my LilyPond module during the meeting and would like to replace the catcode tinkering with some clean Lua logic, if possible. Don't know what will be required for that. And I guess I could use some image/PDF analyzing, e.g. to finally get inline-music working.

Since I need this fix pretty soon, I thought a svn checkout and build might
be a good idea. Getting luatex 0.62 beta compiled and running wasn't a
problem, but the error with metapost still persists. ("This is LuaTeX,
Version beta-0.62.0-2010082217 (rev 3815)")
Is there anything else I would need to get the fix in? Is it in a branch or
is metapost even a lib on it's own? (It seemed to be statically linked, but
I'm not completely sure if I missed something, so I better ask - which I
hereby do.)
Thanks in advance!
Andreas.

[NTG-context] current head title and current number
Hi,
I need to get the current *section/chapter title and number. I figured out
that \fullstructureheadnumber gives the current number. But I can not figure
out what gives the current head title.
In strc-sec.mkiv I found this comment:
\def\currentheadtext{obsolete, use marks}
Is this a hint to use getmarking? I tried
\getmarking[current]
\getmarking[currentsection]
\getmarking[currenthead]
without success. Does anyone know how to access the current title?

The need to run "luatools --generate" is not sufficiently visible (it is in README.MarkIV). Any package that requires user configuration steps should have a mechanism to inform the user that such steps are required. I suspect the damage was already done by the time the OP tried "luatools --generate" , and was perhaps made worse by running the command from a root prompt. > In your case, running luatools --generate does not help, and that is the > bug. You are right, but with a system like context it is sometimes better to avoid stressing the tools by following standard procedures. The OP ended up with /etc/texmf/web2c/pdftex, which suggests that MkII and/or fmtutil tried to install formats under /etc/texmf/web2c. It may be too much to expect luatools to recover when things are not where they belong and files under $HOME are not owned by the user. -- George N.
