Elided page numbers in registers

Elided page numbers in registers

[Duncan Hothersall]

Another question on registers (just getting into indexing!).

I have a book which numbers its pages by chapter, and so page numbers
are 1/1, 1/2 ... for the pages of chapter 1, and then 2/1, 2/2 ... for
the pages of chapter 2.

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).

Thanks...

Duncan

And I add one more related question:

   Is it possible to mix \start...\stopregister with just \register?
   According to this minimal example not. If there is not some secret for
   me, can it be extended?

Please, focus on Duncan:
----------------------------------------------
\defineregister[Name][Names]
\setupregister[Name][pagestyle=\it]
\setupregister[Name][bf][pagestyle=\bf]

\starttext
   Names:
   \Name[bf::]{Hans}
   \Name{Taco}
   \startregister[Name][bf::]{Duncan}

   \page[yes]
   \Name{Hans}
   \stopregister[Name][bf::]{Duncan}

   \page[yes]
   \Name{Duncan}
   \placeregister[Name]
\stoptext
----------------------------------------------

Thanks

To add a further dimension: I'm seeing some other strange behaviours in
a large (15 page) index to a substantial (650 page) book which would be
difficult to reproduce in a test package - to do with ordering of
multiple page references within individual entries, etc.

I would be keen to work on the code if that was possible, rather than
just list problems and hope for others to fix them :-). But I'd need a
point in the right direction.

Thanks,

Duncan

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.
