Description
The way in which e. g. lists or registers are sorted when \placeregister or \placelistofsynonyms is influenced by an appropriate keyword passed to ConTeXt's sort module (sort-ini.lua).
The details lay in a rather obscure set of methods (see source), for which the following short-cuts are defined:
- default = "zc,pc,zm,pm,uc" (uppercase like lowercase, diacritics separate)
- before = "mm,mc,uc" (upper before lower, diacritics ignored)
- after = "pm,mc,uc (lower before upper, diacritics ignored)
- first = "pc,mm,uc" (lower before upper, diacritics separate)
- last = "mc,mm,uc" (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 combination "uppercase like lowercase, diacritics ignored".
- The sorting is also influenced by the current language or the language setting in \setupregister.
Example
Here [1] is a modified example posted on the mailing list by Hans to illustrate the impact of different sorting methods:
\starttext \def\Test#1% {\vbox{{\bf#1}\blank\placeregister[index][language=cz,n=1,method={#1}]}\blank} wanted result: oá öb Oč Öď Oo Öo oo öo Öq öř Oš oů \blank \startcolumns[n=2] \Test{before} \Test{first} \Test{default} \Test{after} \Test{last} \stopcolumns \page wanted result: oá öb Oč Öď Oo Öo oo öo Öq öř Oš oů \blank \startcolumns[n=3] \Test{mc,mm,uc} \Test{mc,zm,uc} \Test{mc,pm,uc} \Test{zc,mm,uc} \Test{zc,zm,uc} \Test{zc,pm,uc} \Test{pc,mm,uc} \Test{pc,zm,uc} \Test{pc,pm,uc} \stopcolumns \page wanted result: oá öb Oč Öď Oo Öo oo öo Öq öř Oš oů \blank \startcolumns[n=3] \Test{mm,mc,uc} \Test{zm,mc,uc} \Test{pm,mc,uc} \Test{mm,zc,uc} \Test{zm,zc,uc} \Test{pm,zc,uc} \Test{mm,pc,uc} \Test{zm,pc,uc} \Test{pm,pc,uc} \stopcolumns \page \dorecurse {2} { \page \recurselevel: \index{oá} \index{öb} \index{Oč} \index{Öď} \index{oo} \index{öo} \index{Oo} \index{Öo} \index{Öq} \index{öř} \index{Oš} \index{oů} done } \stoptext
The key set "zm,mc,uc", "zm,zc,uc" and "zm,pc,uc" give the wanted result in this example.
