The plain tex code shown above fails with a lua error:

My guess is: as math-on (math-off too) is a "discardable" item after a
linebreak, the first math-on node has gone away. So the
math-on/math-off pair has become broken, by which the behavior of
"node.end_of_math" is confused.

Line 9626 with yesterday’s code. Attached are patches for
font-ota.lua and luatex-fonts-otn.lua that guard all invocations
of end_of_math() with checks for the subtype.
I think that the removed math node is a bad thing so that will change in
a next luatex release (i tested a patch but it will not go in the tl
release). (Just like the math node at the end of a line it will have
zero surround in order to make the backend happy.)
In order to avoid the 'current' issue I'll use an overload of
end_of_math in the generic code.
The real solution is to make the built-in end_of_math more strict
(trivial patch ready and tested so that can end up in the next luatex).
In the context code i won't intercept it because end_of_math will do
that at some point.

Math is a tree and not per se sequential, so how about ligatures? Ok, digits might be something special but even then, just swapping one '1' for another one that is not math aware and then is combined with other math characters (lik ein scripts) can have weird side effects. This is not something generic. So, the only way to deal with that properly is to define a font where certain rendering is replaced by another but in the same slot. Even then one really needs to know if the font is suitable for it. I guess that such oldstyle thingies are mostly for simple math that stays close to text, but even then. In context I'd certainly not deal with that by features directly also because the *num properties are not always implemented the same (we have a mechanism for combining fonts anyway). If someone realy wants features applied to math (maybe after the math is processed, then i can imagine that the node font handler is hooked into the mlist_to_hlist callback so that they are applied afterwards. In any case it's very macro package dependent.

[NTG-context] Preparing a weird index.
I have a customer that uses a publisher that has truly weird requirements. The weirdness is that the locaters are not page numbers but paragraph numbers. And some paragraph numbers start with the prefix 'BO' and others with the chapter number. so a correct sequence would be BO.15 3.2 A finished sequence would be goddess @@ BO.15 3.2 3.5 The sort order has to be letter by letter, as defined in the Chicago Manual of Style. Can Context sort and summarize these locaters? I can even change the BO sequence to 0 (zero) and then change it back later on. The key is can Context sort by paragraph number rather than page number for an index. I have looked into Xindy for this job but the learning curve is pretty steep and the documentation pretty opaque. makeindex won't handle decimals for locators. I don't mind doing a little reformatting along the way (I already have for this project) but I don't want to rewrite makeindex or xindy just for this job. -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

[NTG-context] Metapost: I only need a little bit padding
I want to have a rectangle (box) with a word in it (i.g.
"Headline). And all should be rotated 90°.
Below I found a solution I am quite happy with. How can I
get a little bit more padding around the text in the box?
You can copy the example to http://live.contextgarden.net/
- it is running:
\startuseMPgraphic{rotatedHeadline}
% Text "Headline" in a box which is rotated
draw btex {\strut\tfd Headline} etex;
% rectangle with rounded corners
path p;
p := llcorner currentpicture+(0mm,3mm){down}..{right}llcorner
currentpicture+(3mm,0mm)--
lrcorner currentpicture+(-3mm,0mm){right}..{up}lrcorner
currentpicture+(0mm,3mm)--
urcorner currentpicture+(0mm,-3mm){up}..{left}urcorner
currentpicture+(-3mm,0mm)--
ulcorner currentpicture+(3mm,0mm){left}..{down}ulcorner
currentpicture+(0mm,-3mm)--cycle;
pickup pencircle scaled 0.5pt;
clip currentpicture to p;
draw p;
currentpicture := currentpicture rotated 90;
