Hi,

I suspect that the equation numbering in attachment (eq-with-chapter.png) is wrong. Shouldnt't the number be positioned on the right (not on the left)? And in case that this positioning on the left is intentional: is there any way or setting to force the equation number to be moved to the right?

This is a bug in luatex:

Thanks. I'll just put \cite[luatex_807] next to the equation then to make my supervisor happy ;) @BUGREPORT{luatex_807, title = "Bad position equation number Lualatex", journal = "LuaTeX bug tracker", number = 807, year = 2013, month = "feb", url = "http://tracker.luatex.org/view.php?id=807", } Mojca

isn't the the formula simply too long ? \starttext \placeformula \startformula 0\dorecurse{24}{+a} \stopformula \placeformula \startformula 0\dorecurse{25}{+a} \stopformula \placeformula \startformula 0\dorecurse{35}{+a} \stopformula -- luigi

Yes. In tex and pdftex, when the formula is too long \eqno is placed on the next line, shifted to the right. In luatex, the equation number is not shifted.

Compare the output of

\hsize=2cm $$a^2+b^2=c^2\eqno(1)$$ \bye

for pdftex and luatex.

Ah ok Following the link above for the tracker 807, I have made the patch

if ((eqno_box != null) && (eqno_w == 0) && !l) { tail_append(new_penalty(inf_penalty)); shift_amount(eqno_box) = line_s + line_w - eqno_w; append_to_vlist(eqno_box); g2 = 0; and now I have the pdf in attachment -- luigi

it will take a bit more work so no quick patch as we also need to check what happens in r2l mode (the code is similar to pdftex but luatex has a whole bunch of extra code related to directions)

It's what happens with a too wide formula + number (in context you see an extra shift as we also have some distance between the formula and number). It's sort of a side effect of lack of control over what tex does (i can imagine a solution i.e. lap left or right depending on the location but that would then have to be under control of (say) \matheqoverflowmode or so (0 = normal, 1 = lap back into the text, 2 ...). I will have a look at it but it's not a short term solution for your problem the too wide formula, unless you do a local \setupformulas [distance=-2cm] or so).
