i don't know xindy but normally the context mkiv index mechanism is flexible enough (and it can be configured)

Here are some snippets from my old xindy setup...

;; define order of sorting runs (use-rule-set :run 0 :rule-set ("resolve-sanskrit-diacritics" "hr-alphabetize" "hr-ignore-special")) (use-rule-set :run 1 :rule-set ("hr-resolve-diacritics" "hr-ignore-special")) (use-rule-set :run 2 :rule-set ("hr-resolve-case" "hr-ignore-special")) (use-rule-set :run 3 :rule-set ("hr-resolve-special"))

which says that the sorting should be done in the following order: first rules for sanskrit diacriticits, then alphabetic sort of Croatian (hr) characters etc. followed by another set of rules saying to sort Croatian diacritics (I was using latin2 encoding) etc.

Here is example of resolve-sanskrit-diacritics:

(define-rule-set "resolve-sanskrit-diacritics"

:rules (("\\={(a)}" "\1" :bregexp :again) ("\\={\\i}" "i" :bregexp :again) ("\\={I}" "I" :bregexp :again) ("\\\.{(.)}" "\1" :bregexp :again) ("\\d{(r)}" "ri" :bregexp :again) ("\\d{(t)}" "\1" :bregexp :again) ("\\d{(T)}" "\1" :bregexp :again) ("\\d{(d)}" "\1" :bregexp :again) ("\\d{(n)}" "\1" :bregexp :again) ("\\d{(s)}" "š" :bregexp :again) ("\\d{(S)}" "Š" :bregexp :again) ("\\~{(.)}" "\1" :bregexp :again) ("\\'{(c)}" "ć" :bregexp :again) ("\\'{(C)}" "Ć." :bregexp :again) ("\\'{(s)}" "š" :bregexp :again) ("\\'{(S)}" "Š" :bregexp :again) ))

which says that e.g. 'ṣ' which is pronounced similar to Croatian 'š' should go in the same letter-group, same with 'Ś' which goes to 'Š'. 'ṛ' is pronounced as 'ri' and it should goes in the letter group 'ri' etc.

Of course, at that time, without proper Unicode support, it was a bit cumbersome but I was able to see everything properly in LyX as well as properly sorted in the final PDF/PS outputs.

Is something like that possible in ConTeXt?

See sort-lan.lua ... you could define a pseudo-language for this and use that one for sorting. The actual sorting is driven by a sequence of steps that (can) involve uppercase, lowercase, shape, unicode, specific order etc. Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
