Re: sorting texinfo indices?

- download the texinfo source code.  It's in C.
- download the texi2html source code.  It's in perl.
- implement your favorite sorting routine as an optional feature
  in both those projects.  Alternately, add hooks to those
  projects so that users can specify their own sorting routines in
  some language.
- wait 1 year for new releases to come out in those projects
- get the sorting you want in those indexes.

As I said in
http://lists.gnu.org/archive/html/lilypond-devel/2009-07/msg00710.html
it's pretty much beyond our control, and IMO totally not worth the
effort involved.

I like it!  Although, could the lily be shrunk to about 50% of the
current size?  It obscures a bit too much of the music.

We might also want to find a more complicated / fancier snippet;
maybe some lyrics + the top staff of a piano?

You reviewed patches and explained some of the internal details.
IMHO, that's plenty.  At least, plenty to be a "development team".
If you'd rather be listed as "Reviewer and emeritus professor" or
something like that, I won't object.  :)   But I still think you
should be in the main team.

Thanks for the report.

In current git, the bbox should be more accurate.

I think I might have figured out how to make \arpeggioArrowUp and
its kin select the appropriate context depending on whether 
'connectArpeggios is set. Can someone look at this and check to
make sure it's legit?

Thanks!

One small thing - just figured out that the above conditional
tests *are* necessary.

Have you tried using ly:context-property-where-defined instead of
searching for PianoStaff explicitly? There are non-PianoStaff contexts
containing Span_arpeggio_engraver, after all. Other than that, this is a
very cool trick!

Joe,

Thanks for the tip. I rewrote arpeggio-generic with ly:context-
property-where-defined and also made some changes to arpeggioNormal.

Also, line 281 of property-init.ly says this:

% For drawing vertical chord brackets with \arpeggio
% This is a shorthand for the value of the print-function property 
% of either Staff.Arpeggio or PianoStaff.Arpeggio, depending whether 
% cross-staff brackets are desired. 

This is completely false, right? Otherwise these commands would work
without the \applyContext gymnastics I've been coding in this thread.
If my code (below) gets approved, I think I'll either remove the
comment it or change it to:

% These commands look for 'connectArpeggios (cross-staff arpeggios)
% to determine the proper context in which to operate.

Any objections? How close is this to being acceptable? I'll wait for
approval.

Okay, this is not ready yet. I found a confusing problem. When setting
connectArpeggios to #f after it has been #t, there's some issue with
the unreverted PianoStaff stencil somehow overriding the new Voice
stencil. Or something. I'm not really sure -- it's confusing.

You can see it in action below (note that you need the definitions
from the previous post for this to make sense).

Maybe it's because I'm so tired, but this is so confusing to me that I
feel that anyone who is able to explain this ought to get a special
prize. Unfortunately, I don't have any special prizes to give.

Sometimes computer programming reminds me of this:
http://www.puzzlemethis.com/cgi-bin/puzzle/scan/st=db/ml=33/co=yes/sf=category/se=Disentangle%20%26%20Blacksmith/op=eq.html
Does anyone else feel like this from time to time?
I think I'd feel better if I knew that you guys did!

scm/kpathsea.scm

Hello,

Is scm/kpathsea.scm used anymore?  If not, can it be removed from
LilyPond's source?

Thanks,
