Dear list,

I have the following sample:

\showframe \definefontfeature[smcp][smcp=yes] \definefontfamily[mainface][rm][GFS Didot] \setupbodyfont[mainface]

\setupregister[index][style=\addfs{smcp}, command={\hfill}] [...] Is there no way to center the head in indices? [...]

As to the centering, it works fine here with command=\centerline . Index heads (a, b, ..., β, ἄ, ...) are centered over each of the two columns.

I got the same results, but I wonder whether this is the right way of doing it.

But that last bit is a problem. ἄ is indexed separately from α, and it is placed after β. I don't think you want that. I do not know how you would support more than one language in a single index sort.

It was only a test and the font has some issues with OpenType features. The real problem comes with this source: http://www.ousia.tk/grc-index.tex (output in http://www.ousia.tk/grc-index.pdf). Each word-starting letter with a different diacritical mark is considerer a different letter for the index sorting. It seems to be a problem only related to ancient Greek, since the following works as expected: \mainlanguage[es] \define[1]\indx{#1\index{#1}} \setupregister[index][n=6, balance=no, command={\centerline}] \starttext \indx{a} \indx{á} \indx{ñ} \indx{n} \indx{ü} \indx{u} \indx{A} \indx{Á} \indx{Ñ} \indx{n} \indx{Û} \indx{u} \placeindex \stoptext German is rather tricky (sorting rules in German are tricky, too), but it works as it should (after fine tuning): \mainlanguage[de-at] \define[1]\indx{#1\index{#1}} \setupregister[index][language=de-AT, balance=no] \starttext \indx{üben} \indx{Übung} \indx{U-Bahn} \currentlanguage \placeindex \stoptext I guess having different language names (de-at and de-AT) for \mainlanguage and index sorting is unnecessarily complex. If it were possible, I think it would be extremely helpful to be able to invoke languages by their XML standards (or https://tools.ietf.org/html/bcp47). This would mean grc for agr, de-1901, de-AT and de-CH for deo, de-at and de-CH... and so on. I mean this as full-working alternatives, not as replacements that would break existing compatibility. But even defining a language synonym doesn’t work with index sorting: \installlanguage [de-AT] [de-at] \mainlanguage[de-AT] \define[1]\indx{#1\index{#1}} \setupregister[index][balance=no] \starttext \indx{üben} \indx{Übung} \indx{U-Bahn} \currentlanguage \placeindex \stoptext Hans, how about improving alternate (standard for the rest of markup) language invocation and allowing the main language to specify the sorting order in German indexes too?
