Thanks for your responses so far!
The reason I need this index is that I have to provide evidence of
"a huge volume of mails" on a given topic, without actually sharing
the emails. So I need a PDF index. Hence I thought making an HTML
table, and then printing that. Easiest.
A screenshot/bitmap approach would be very hard to turn into a
useable PDF, I think.
Sam is right, threads are digraphs, but Mutt displays them in a
table, and I think that's a good compromise.
I don't think it will be better or easier than what you've done. But
you could try using a '|' filter in $index_format to append some
output to a file as a side effect. It would still entail manually
pgdn'ing through the index.
Not a bad idea, but unfortunately, the Unicode characters used to
represent threads in mutt's index seem to be some sort of
ncurses-special, and the whole thing would need parsing. But this is
definitely an interesting approach, as I could probably craft an
`$index_format` that generates HTML `<tr>`'s, and PgDn'ing over a
thousand messages might be something the X repeat buffer can do. ;)
I knew why I'd ask here! ;)
Thanks,
