Dear Hans,

this is how tex works: just look at inline math

Yes, you are right. To start a new line with a sign may be a preference of me and some others. I found a document which illustrates the different displays of a long equations in LaTeX. https://www.andy-roberts.net/res/writing/latex/longeqns.pdf https://www.andy-roberts.net/res/writing/latex/longeqns.pdf I think that I ask you too much. You may leave it to user to choose. Thank you for the example that I just saw. It looks good to me. Best regards, Dalyoung

i played with it a bit but had to adapt the engine for a bit more control (stepwise the matyh machinery is opened up i.e. hard coded steps become configureable)

anyway, the question is not implementing but control: it's not default tex behaviour so it has to be turned on (and then after a while we forget that it can be turned on i guess)

(no clue what keyword to use for controling it)

Hans

Let me quote the TeXbook (page 195):

»Although formulas within a paragraph always break after binary operations and relations, displayed formulas always break before binary operations and relations.«

given that one uses alignments

On the other hand, right above this paragraph, it says:

»It's quite an art to decide how to break long displayed formulas into several lines; TeX never attempts to break them, because no set of rules is really adequate.«

right, so we're stuck .. anyhow, some future mkiv beta / luatex combination will provide \setupformulas[split=yes,align=flushleft] % already there \setupmathematics[setups=math:spacing:split] % needs new engine so that you split differently (one can then prevent an unwanted split with a large penalty) 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 -----------------------------------------------------------------

Dear Hans, Aditya and the list, I have tested the new auto breaking feature for formulas and have encountered some issues that I have summed up in the attached file. It would be great if this issues could be eliminated. Best Mathias

While you are tweaking formulas, would it make sense to add a key-value interface for \startformula, so that the following also works:

\startformula[split=yes, align=flushleft] ... \stopformula

We can remain backward compatible by check if the argument to formulas is an assignment or not.
