Hans, many thanks for the recent fixes on index sorting in the new ruby scripts. Can I offer another test file in which some errors still show up, in the hope that these too can be ironed out? The following shows two problems, culled from a much bigger project. It should be clear from the output what the problems are, but basically 1. there are three separate spans (\startregister...\stopregister pairs) with the same term content ("these three separate spans coalesce") which get coalesced into one strange a-b-c-d span, despite having been given different sort keys (I added numbers to the end of the sort keys to differentiate them). 2. there are three refs and a span all with the same term content ("these mixed refs and spans are in the wrong order"), and they get sorted into the wrong order in the output (the span comes before the refs, despite coming after in page order). So in my output, my index page at the back has the following content: these mixed refs and spans are in the wrong order 1/12–1/13, 1/2, 1/10, 1/14 these three separate spans coalesce 1/1–1/2–1/5–1/7 whereas what I'd hope to see is: these mixed refs and spans are in the wrong order 1/2, 1/10, 1/12–1/13, 1/14 these three separate spans coalesce 1/1–1/2, 1/3–1/5, 1/6–1/7 Really hope you can hammer out these two bugs, it would really help me!
