Perfect! Thank you.
It looks like \currentreference number is initially empty, and when
\doifelsereferencefound succeeds it is set to that value, and remains
set to that value until another \doifelsereferencefound is encountered.
If \doifelsereferencefound fails, \currentreference is again empty. Is
that correct?
yes, btw, there are some more \currentreference* available

(A year later) Is there still no way to do this without resorting to the

The need is to take a label reference number and display it under a
different numberconversion regime.

I tried using \mathboxanchored, and was able to get the bottom two equations
shown here. (The top equation uses \hpos, for comparison.)
mathboxanchored.pdf
Description: Adobe PDF document
There are two problems that I didn’t know how to fix.
1) The line connects to the box including the subscript or superscript, not
just to the e.
2) I cannot make multiple connections to a single object, like the e^\mu in the
center. If I try to connect top and bottom, I get no connections anywhere in
the entire document.
The code for the formulas is:
\startformula
% Each \connectboxanchors works alone, but both together make trouble:
\connectboxanchors[top][top]{X}{Y}
%\connectboxanchors[bottom][bottom]{Y}{Z}
\mathboxanchored{X}{e}_\alpha \mathboxanchored{Y}{e}^\mu
\mathboxanchored{Z}{e}_{\dot\beta}
= \textfrac{1}{\sqrt{2}}\sigma_{\alpha\dot\beta}^\mu
\stopformula
I added code to turn the arrow produced by \connectboxanchors into my
contraction overlay, but that doesn’t affect these issues.

> it on the e + super/subscript?
Yes, we only need to anchor to e.
Thanks!

Re: [NTG-context] \hpos in math
On 12/6/2022 12:39 AM, Gavin via ntg-context wrote:
Hello List,
I am working on a project which combines graphics with formulas, like this:
My code for creating this formula is attached. It works well, but I have a
couple of questions that could make it work better.
1) Is there a mathematics version of \hpos? The contents of \hpos are set as
text, even when \hpos is in mathematics, so I wrote an \mpos macro that uses
\hpos but sets the contents as display-style math. This isn’t great for
spacing, and it does't adapt to different math styles. \framed has a math
version, \mframed, that sets the contents in the appropriate math style. If
anyone know a way to accomplish that with \hpos, I’d love to know.
there actually is a subsystem that keeps math as-is-it (styles and
spacing and such), see attached
2) Is there a way to limit the scope of the \hpos labels to a single formula.
This could turn into a book length project, with several formulas per page and
several connections per formula. If every \hpos in the entire book needs a
unique identifier, I could go mad. Under no circumstances will I connect one
formula to another, so I’d like to be able to use something like
\hpos{A}{…}…\hpos{B}{…} in each formula. Any suggestions?
one problem is (and i'm working on that) that one could want multiple
anchors on a math atom as well as pu tit on the nuclues only
I’ve got to say, LMTX is an absolutely amazing tool for this project, which
includes complicated networks of connections above and below many formulas. The
integration of TeX, MetaPost, and Lua makes this project tremendous fun.
that's the idea
P.S. For the curious, I’m using a method for doing General Relativity based on
spinors rather than tensors, following the methods of Penrose and Rindler in
their 1985 books “Spinors and Space-time.” In the typesetting example above,
the e_\alpha and e_{\dot\beta} are basis spinors (one left-handed, one
right-handed). The e^\mu is the Infeld-van der Waerden symbol relating the spin
basis to the coordinate basis. The connections are spinor index contractions.
The formula above relates the components of the Infeld-van der Waerden symbol
to the Pauli sigma matrices. This relationship only works in flat space, so
this is an easy example! [Penrose and Rindler, vol 1 p. 125]
in your example we need a way to anchor on just the 'e' right? or do you
want it on the e + super/subscript?
