Ahoi,

usually, uppercase index entries are sorted before all lowercase entries. Is there a simple setup to change that?

i.e. I need the sorting sum - Sun - sunny instead of Sun - sum - sunny

I know I can influence sort order for single entries, but I’d like a general setting.

Hi Hraban,

I think this may achieve what you want:

\setupregister[index][method={zm,zc}]

I hope it helps,

Thank you very much!

But reading through that and the source I’m still confused.

I’d like to write a proper explanation for the wiki (and my book).

Is there anywhere documentation about the meaning/goal of the presets or algorithms?

Are these codes translatable into something like "ignore diacritics", "ignore upper/lowercase" etc.?

Ok, I think I got it... For a proper sorting, you first apply a "mapping", then a "casing" and finally "unicode". Presets: default = upper like lowercase, diacritics separate before = upper before lower, diacritics ignored after = lower before upper, diacritics ignored first = lower before upper, diacritics separate last = upper before lower, diacritics separate * If you don’t set the sorting method, the preset "first" ist used (and not "default"). * There’s no preset for the (in my eyes most meaningful) combination "upper like lowercase, diacritics ignored" (zm,zc,uc). * Aren’t language specific sorting rules possible at the current state? Or does "unicode" handle that? E.g. -- DIN 5007-1 (German default sorting) is like zm,zc,uc, but ß should be sorted like ss. -- DIN 5007-2 (German phonebook sorting) would additionally require umlauts to be sorted as ä = ae etc. -- Austrian phonebook sorting sorts umlauts after base vocals, i.e. a, ä, o, ö, u, ü, s, ß. -- Danish and Norwegian: x, y, z, æ, ø, å -- Finnish and Swedish: x, y = ü, z, æ, ä, ö, ø, å (until 2006 v = w) -- etc. (according to https://de.wikipedia.org/wiki/Alphabetische_Sortierung) If nobody objects I’ll add this to the wiki.

sort-lan.lua contains different language definitions.

Ah, thanks for the hint. But how can I employ these definitions with index/list ordering? Setting mainlanguage and method "*,uc" doesn’t seem to do the trick.

Among others: DIN 5007-1, DIN 5007-2, Duden.

Hans, please add the replacement { "ß", "ss" } to definitions['DIN 5007-1'] and definitions['DIN 5007-2'] Thank you!

Swedish doesn’t contain ø (according to https://sv.wikipedia.org/wiki/Ø, it is replaced with ö) or ü (it is a foreign letter to their alphabet). and "fi" seems to order the way you describe. And v is different from w.

I wouldn’t touch it then, who knows how accurate German wikipedia is...

I would say, Finnish isn’t included in sort-lan.lua.

Yes it is. (http://source.contextgarden.net/tex/context/base/mkiv/sort-lan.lua)

Please, it would be extremely helpful (I remember thinking that registers didn’t make any sense in ConTeXt, before someone helped me).

As soon as I understand how the language dependent sorting works... Greetlings, Hraban --- https://www.fiee.net http://wiki.contextgarden.net https://www.dreiviertelhaus.de GPG Key ID 1C9B22FD

You can add them. AFAIK the ß replacement was added later (no idea who sent it) because it wasn’t in the patch I found in my mail archive. Wolfgang
