Michael— Thank you so much for your very helpful response. 1. \unskip works well. 2. What I currently have is admittedly an ad hoc system for encoding my indices. As you note, the system works for page numbers > 99 where line numbers < 99. When line numbers > 99, I adapt the sort key differently: thus, for Cleomedes, *Cael*. I have [CleomCael105001] for 1.5.1. This works (in MKII) but only because the number of entries is very small. 3. I like your MKII solution—it is much more general, works well on what I have, and is certainly less taxing to encode. Many thanks! The book that I trying to index right now is the last of my MKII projects. So I am also interested in, and very grateful, for your MKIV solution.

1. For \ab you might want \def\ab{\unskip} since the space is not the same as the width of a digit.

2. Does your solution work with line numbers greater than 99? I tried to implement your idea and I got the order 25.7, 25.117, 25.37. Probably more than 99 lines never occurs on a page, so it's a non-issue. But Homer, for instance, is often referred to by Book.Line, and the lines go past 100. Again, perhaps a non-issue for you.

3. My own attempts: At first I though what a nice opportunity for me to learn a little more Lua, which it was. After, I read you wanted a MKII solution. Well, I'm embarrassed at how long I took to do the MKII, but I'm not good at controlling expansion. Anyway, it automatically generates sort keys for the pages by converting digits to letters and padding with initial a's, so that each page or line number is a fixed length (4 in this case, up to 10000 pages/lines). For instance, 123.4--56 is mapped to abcdaaaeaafg MKII does not seem to sort digit-based keys reliably; MKIV does, and you can just pad out the digits with zeros. The complete sort key that worked was the catenation of the author, text, and locus key, which is similar to what you have.

MKII: \defineregister[Passage][Passages] ... % interface to register -- \locuskey indirectly returns a key in \nextkey

\def\MyPassage#1#2#3{\locuskey{#3}\expandoneargafter\doMyPassage{\nextkey}{#1}{#2}{#3}} \def\doMyPassage#1#2#3#4{\Passage[#2#3#1]{{#2}+{#3}+{#4}}} % Def. of \locuskey#1 % In: #1<-p1[.l2[--l3]] Out: key stored in \nextkey ... (see attached file, if interested)

MKIV: % interface to register -- expansion in MKIV must be different, because a direct approach works: \def\MyPassage#1#2#3{\Passage[#1#2\locuskey{#3}]{#1+#2+#3}} % Def. of \locuskey \startluacode userdata = userdata or { } function userdata.locuskey(x) context(string.gsub(x,"(%d+)",function (s) return string.format("%04d",tonumber(s)) end)) end \stopluacode \def\locuskey#1{\ctxlua{userdata.locuskey("#1")}}

The Mark IV/Luatex one was much nicer, less frustrating to figure out.

For anyone interested in producing classical indices locorum, I have devised a way that seems to work, although it is not that elegant.

The first step is to modify the sort keys by counting the number of digits in the page number: thus, [AuthorText01] for pages 1–9, [AuthorText02] for pages 10–99, and so on

The next is to insert the command “ \ab” (note the space) when the line number is a single digit: thus 391. \ab{}2 but 391.12 in the entry specification {Author+Text+page.line}

For \ab, I have:

\newdimen\digitwidth \setbox0=\hbox{\tfx\char32} \digitwidth=\wd0

\def\ab{\tfx\kern-\digitwidth}

The hitch here is that the font size is not context dependent.

I have been trying to index the passages cited in a book and would be grateful for some tactical advice.

There are several works by a single author, and it is customary to cite each text by page and line number, as in 1253.12 (page 1253, line12), for example.

I have a sort key for each work. But now I need a way to get the entry

1253.7 (page 1253, line 7) before the entry 1253.12 (page 1253, line 12).

\[Passage[AuthorText]{Author+Text+1253.07}1253.7 or \[Passage[AuthorText]{Author+Text+1253.07}1253. 7 would work, but it is really better to have the index entry as “1253.7” rather than as “1253.07” or “1253. 7”

I have experimented with different sort keys—e.g., AuthorText125307—and can generate an index with the 1235.7 and so on in the proper place and form, say, before 1253.12.

But then the problem is that I also get entire sequences of entries out of order (485.19, 485.21 before 477.31, and so on). Very puzzling. (Restoring the sort key AuthorText removes the latter problems but then leaves 1253.7 in the wrong place.)

If anyone has experience with this or just some ideas for a solution, their suggestions will be most welcome.

I am using the MKII in the latest ConTeXt standalone.

It does indeed! Excellent! A. On Sat, May 26, 2012 at 9:21 AM, Rogers, Michael K wrote:

Thanks, Alan. Actually, I now think MKIV works without any trickery. I was perhaps too eager to try a Lua solution. \Passage{Author+Text+Locus} seems to work fine in the beta today.

Cheers, Michael
