Hi Hans,

if I get it right this means that you provide a mechanism that brakes formulas automatically across several lines? I appreciate this very much! Thank you for including this into the next beta! Would it be possible to do something like that for breaking long formulas across pages (or is that maybe included in the new mechanism)?

Okay, that would be really great. Maybe a semi-automatic breaking across pages could be doable. The AMS package for LaTeX implements something like that. If you write \allowbreak (I am not absolutely sure if this is the true command, but it is something like that) at a line of an equation with multiple lines the typesetting algorithm knows that the formula can be broken across pages at that point. If something like that could be done in ConTeXt it would be really great. At present it is somewhat complicated to handle equations with many lines since you have to typeset the text and check if everything fits. If you could mark certain lines of an equation to be allowed to be broken at the end of a page, working with multiple line equations would be much easier and faster.

Thanks. I'll play around with it. Aditya

That looks really good! Will it be possible to combine that with \startmathalignment? And if not can you pass several \alignhere commands and force breaking at user defined places? (I tried out to test it myself but the new feature is not yet uploaded to the garden version.)

i didn't test with alignments only one \alignhere per formula Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

i.e. (poor mans) multiline display math

Interesting. 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...

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 -----------------------------------------------------------------
