Hallo Hans and other ConTeXters,

I have started to collect and clean up Czech ConTeXt localization. And I 
have discovered that Tomas Hudec includeded Czech (non-trivial) sorting 
rules into texutils.pl (calling czsort.pl from Jan Pazdziora). 
Unfortunately it was not incorporated into official ConTeXt disribution.

Hans, what is your prefereble solution in case of local sorting rules? I 
know, there is \definesortkey, but this mechanism is insufficient for 
Czech. I think that calling external Perl sorting routine is a suitable 
solution. If so, it can be incorporated into current version? Files are 
attached.

Thanks
Vit Zyka

in order to do that:

- the pm code should move into texutil
- we should find a way to hook the switch into texexec

now, apart from such an effort, i think we should rethink sorting;

- no funny encodings which demands the sorter to be encoding aware
- no locale dependencies
- readable sorting code -)

steps:

- write named glyphs to the output:
- no longer use direct code in definecommand and defineaccent, i.e.
- define the fallbacks as 'definecharacter ones'

the last two steps actually come first (since adam l. is quite fluent in the 
character names and such, i guess that the both of us need to look into that and 
do that in 'one move'); after that i can rewrite the sort/index code to become
aware of named glyphs and languages, and we can then plug in language specific 
sorting rules [taking care of xml at teh same time]

[it's worth considering to drop the non etex code]

named glyphs are not so much a problem, but we need to clean up the
fallback encoding defs a bit in order to prevent funny expansion

\def\literateencodedtokens
   {% \let\dohandleaccent   \keephandleaccent
    % \let\dohandlecommand  \keephandlecommand
    \let\dohandlecharacter\keephandlecharacter}

\def\convertmeaning#1\to % watch the double expansion !
   {\bgroup
      \honorunexpanded
     %\dontexpandencoding % new
      \literateencodedtokens % newer
      \xdef\@@globalexpanded{#1}%
      \xdef\@@globalexpanded{\@@globalexpanded}%
    \egroup
    \convertcommand\@@globalexpanded\to}

\protect

\enableencoding[texnansi] \setupregister[index][keyexpansion=yes]

\starttext

\defineactivecharacter * {\eacute} test \index{test \eacute * \'e test}

\stoptext

Hallo Hans,

thank you for your positive responce. Since I am still a bit confused in 
the ConTeXt low and high level encoding macros (but a bit less after 
solving the last week UTF-8 -> IL2 problem - despite of the reason was 
in my old ConTeXt distr.) I need a bit more details about how to contribute.

OK. So, each sorting rules will be represented by cmp($a,$b) function? 
And $a and $b should be glyps, shouldn't they?

Sorry, output of what? Where are the commands? ???

Great.

All right. etex can be everywhere now.

I totaly do not known what the code bellow illustrates.

So, what to do?
