Subject: [NTG-context] Custom sorting of "pseudo-language" in a register
To: mailing list for ConTeXt users 
Hello all,
I’m just getting acquainted with ConTeXt, and I am finding it so much
more suitable for my work and needs. Thanks for the great software.
Here’s my situation. I write in Slovene and in English, and I need to
make numerous references to biblical passages. I want to create an
index of these citations, but I want them in the order they appear in
the Bible rather than alphabetical order. Henri Menke provided a
perfectly workable solution on TeX StackExchange[^1], but because this
is a multi-year project, I wanted to find a bit more permanent
solution. I discovered I can use Lua LPEG to parse and normalize my
citations so they are referenced in a uniform style.
My problem comes in the register sorting. Hans, I saw where in the
paste you have recommended a “pseudo-language” to implement a custom
sort in such a situation. I have almost figured out how to accomplish
this. (See the MWE below.) I have no problem with single word sections
(Genesis, Exodus, etc.). I can turn off indicators, do the custom sort
(see below), and I get the intended result. If I have a multiple word
title (Evangelij po Janezu), that technique doesn’t work. The
replacement for more than one word (or if a number is involved, like
1John) doesn’t seem to work. I have no doubt there is a good reason;
I’m just a newbie!
It seems my options are to:
1. Figure out how to do a replacement for a phrase or a book with a
number in its name. Then this technique seems to work ok.
2. Or to add an entries and figure out some way to not print the first
level in the index. So the indicator will be the book name, and
underneath the chapter and verses will be listed with out the book
name being repeated.
Are there any ideas to point me in the right direction?
You're bitten by the cleaner that kind of normalizes entries as you can 
see when you say

\enabletrackers[*sort*]

replacing spaces by \0 can help but that sort of assumes that you know 
what happens inside

So, i added some code to handle that. I also added a helper so that you 
can do:

\startluacode
     local list = {
         -- old testament
         "Genesis", "Exodus", "Leviticus", "Numbers", "Deuteronomy", 
"Joshua",
         "Judges", "Ruth", "1 Samuel", "2 Samuel", "1 Kings", "2 Kings",
         "1 Chronicles", "2 Chronicles", "Ezra", "Nehemiah", "Esther", 
"Job", "Psalms",
         "Proverbs", "Ecclesiastes", "Canticles", "Isaiah", "Jeremiah",
         "Lamentations", "Ezekiel", "Daniel", "Hosea", "Joel", "Amos", 
"Obadiah",
         "Jonah", "Micah", "Nahum", "Habakkuk", "Zephaniah", "Haggai", 
"Zechariah",
         "Malachi",
         -- new testament
         "Matthew", "Mark", "Luke", "John", "Acts", "Romans", "1 
Corinthians",
         "2 Corinthians", "Galatians", "Ephesians", "Philippians", 
"Colossians",
         "1 Thessalonians", "2 Thessalonians", "1 Timothy", "2 Timothy", 
"Titus",
         "Philemon", "Hebrews", "James", "1 Peter", "2 Peter", "1 John", 
"2 John",
         "3 John", "Jude", "Revelation",
     }

     sorters.definitions['bbt'] = {
         replacements = sorters.replacementlist(list),
     }
\stopluacode

\defineregister
   [booksort]
   [language=bbt,
    n=1,
    indicator=no]

\starttext

     One   \booksort{Genesis+5.2}
     Two   \booksort{Exodus+2}
     Three \booksort{Genesis+45}
     Four  \booksort{Philemon+2}
     Five  \booksort{John+45}
     Six   \booksort{1 John 1+45}
     Seven \booksort{2 John 2+45}

     \blank[3*line]

     \placeregister[booksort][language=bbt]

\stoptext

It probably makes sense to make this into a module but then we need to 
collect a few lists.

I'll upload a beta.
