Re: [NTG-context] Elided page numbers in registers
On 31 Aug I wrote:
I have page ranges in my index, such as 1/1-1/3, or 2/24-2/26.
I would like these ranges to be elided - in other words, the first one would read 1/1-3 (remove repeated chapter number), and the second would read 2/24-6 (remove repeated chapter number and also the repeated 2 in page number).
Question: is there an already existing system to do this? I guess no :-)
Followup: I would be willing to help to code this if it doesn't exist (I have some experience with such systems) if someone can point me at the right bit of code to look at (things seem to be changing around texutils, newtexexec etc. so I don't want to start at the wrong place).
Sorry to be a pain, but can anyone help with this? I'm converting a legacy system, in which everything (cross referencing, tables of contents, indices) was hand-coded in plain tex and Perl, across to ConTeXt. The advantage of having hand-coded the indexing stuff was that I could easily add features like eliding, or funny sort orders. I now need to reproduce the same output. I suspect I could apply the same techniques to the ConTeXt code, but I don't want to embark on a fool's errand if (a) it's already done somewhere, or (b) the code I hack is about to be replaced. Thanks, Duncan

My experience: It is not implemented in (old) texutil.pl. It is even not implemented in simpler only-page-number case. In the code there is secret switch '$CollapseEntries', by default it is off. Switching manually on leads to all index page entries collaps to one (generally noncontinuous) range. The same sad result you obtain if you use startregister...stopregister pair. If you know Perl it is not difficult to insert such stuff for one application. It is very difficult to create a general solution. I have no (positive and deep) experience with new ruby texutil equivalent. vit
(b) the code I hack is about to be replaced.
