When you have \mainlanguage[cz] in your document context should use the czech
sorting mechanism, when you english as main language you can use them in the register
with \placeregister[index][language=cz].

You can also influence the sorting with the method key for \placeregister: http://www.ntg.nl/pipermail/ntg-context/2010/052950.html

That main language is set correctly. While the current implementation
supports a single character order, in czech at least two are required - the
primary one for the first pass and the secondary for the second pass. It
ensures the correct order of accented characters.

Anyway, I dive into the code and found an entry point in the sort-ini.lua
file.
In the comparers.basic(a,b) function I call a customized code instead of
basicsort().

Thanks to my code I can produce desired outputs now ;-)

But all my lua code is directly in that file, which is not ideal as it is
overwritten with every ConTeXt update. Is there any general recommendation
how to make these customization more flexible?

Thanks, Jan

Index - custom sorting

[honyk]

Dear All,

czech sorting has a quite complex logic. How can a default index entries
sorting be overridden? 

Using a macro or somewhere under the hood via a lua code? I am a total noob
in this. Btw, as a Java programmer I have it implemented already in Java so
I hope it won't be a huge task to convert it into something else...

Any hint is appreciated.

Jan
