The "\definebar[...][inlined]" doesn't look quite right though -- the
issue that I'm having is that I can't figure out how to highlight across
both sides of an \alignhere without any questionable hacks. Unless the
new "inlined" does work across an \alignhere and I'm just not seeing it
in the example.

I can confirm that it works over \alignhere. Hans is doing some black
magic, but I guess he did not want to show off by including the whole
line.
Indeed, no need to show of the obvious

Especially when it would not pass the rigourous accessibility check (esp

No, align does not split over pages. But ordinary formulas do. You can
play with \alignhere and \breakhere, and add text with
\texthere[right]{some text} or \texthere[left]{some other text}.

Thanks, but unfortunately not. I guess, I simplified the MWE too much.
This does not align the b and c. It should become clear here:
```
\startformula
a = \alignhere (b, thisislonger) \quad \text{with}
\breakhere b = \text{something}
\breakhere thisislonger = \text{someother}
\breakhere
\text{somelong} = \alignhere bla

The example given above consists of two formulas, and the new broken formula type simply does not fit. You can play with more than one \alignhere, but they will only set new align points.

Hi Jethro,
Temporary workaround: use the simplecommand.
\definemathmatrix[pmatrix][matrix:parentheses][
simplecommand=pmatrix,
]
\starttext
% \placeformula[-]
\startformula
\startalign
\NC A \NC = \underbrace{\pmatrix{5,5;-1,7}}_{B} \NR
\NC\NC = \underbrace{\pmatrix{2,1;4,2}}_{C} \NR
\stopalign
\stopformula
% \placeformula[-]
\startformula
A \alignhere=
\underbrace{\pmatrix{5,5;-1,7}}_{B}
\breakhere
=
\underbrace{\pmatrix{2,1;4,2}}_{C}
\stopformula
\stoptext
But the code you were using should in principle also work.

Dear Hans,
Thank you for the new way to align math formulas.
It is great to use “\alignhere”, “\breakhere”.
However, I got a problem today.
If I use it with figures side by side, then the alignment is broken.

Maybe a semi-automatic breaking across pages could be doable. The AMS package for LaTeX implements something like that.

An important reference for automatic breaking of multiline display are the notes of Michael J Downes included in the documentation of breqn: see section 14 (page 16) of http://ctan.math.washington.edu/tex-archive/macros/latex/contrib/breqn/breqn.pdf I remember a talk by giuseppe about nath (or so) that did something nice but anyway, the main question with that kind of trickery is if one is willing to add structure info or not .. anything semi-clever will be limited. (Ignore the implementation details, which were a series of hacks to make things work in pdftex, but section 14 explains the different display math layouts and a strategy to choose between them. It will be really nice to have something comparable in ConTeXt. You mean these boxed lines? I'm not a math expert so the subtle details are lost to me. I'd rather start from reasonable demands (after all very complex stuff often is best done manually anyway). For instance foo = bar + bar + bar gnu + gnu is doable without much trouble if one is willing to enter foo = \alignhere bar + bar + bar gnu + gnu and such. - Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl - ___ 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://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___
