Grace notes, accidentals and docu problems ...

Hi,

I collected some bugs/features, missing features in lilypond 1.5.x
Latest version tested: 1.5.47

Grace notes:
1. Grace notes work quite well since 1.5 but I'm missing a feature.
   Example 1 can not be compiled using lilypond.
2. If grace notes are appended first all notes in all voices connected to the
   same beat as the main note are set before the grace notes start. I have
   seen an example in literature where the grace notes start as soon as
   possible after the main note.

   lilypond:
   voice 1:      O             <grace notes>
   voice 2:      o' o' o' o'

   example:
   voice 1:      O <grace notes>
   voice 2:      o' o' o' o'

   where O is a half note and o' are eight's.

Overlapping accidentals:
3. Flats may overlap, e.g. if you have violin key and a <b es'>-chord the two
   accidentals overlap (see example 2).

Documentation:
4. If the documentation is not split, you get
     ./Documentation/user/out-www/lilypond.html which is ok

try this patch,

Re: Grace notes, accidentals and docu problems ...

Hi.

1. The patch plus the context work-around works alright, although the beams of
   the grace notes and the other beam cross each other.

2. The idea of using space notes in a second voice does not work. I get at most
   something like

   voice 1:    O  g    g    g
   voice 2:    o'   o'   o'   o'

   for <c2 {s8 \grace{ ... } s8 \grace{ ... } s8 \grace { ... } s8 }>
       c,8 c,8 c,8 c,8

   that is both grace notes and the notes of the second voice alternate.

Try:

\header{
filename  = "bugs-3.ly"
title     = "Bugs 3"
} 

\version "1.5.0"

voiceA = \notes{
	\time 6/8 
	\clef violin
	\key c \major
	<c''2 ( { s8 \grace { [c''16 c''16] } s8 \grace { [c''16 ) c''16]} s8 \grace

Oh, I see .. You want to have the top and bottom notes be completely
independent. It's not possible currently. If you want to hack C++, you can
look into "loose columns" as a solution. If not, you can try faking
it, using \times and manually setting size properties.

1.4.12 stem direction bug

In the following example, the automatic stem direction engine does strange 
choices that result in a weird beam vertical offset, so I have to use 
\stemUp/Down manually:

\version "1.4.12"
\score {
  \notes \relative c'' {
  \key g\major
  [d8 \times 2/3 {g16 fis e]} \times 4/6 {[d a b c d c]}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
[<b8 d, g,> \times 2/3 {g'16 fis e]} % <--- here
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
  \times 4/6 {[<d d,> <a d,> <b d,> <c d,> <d d,> <c d,>]} |
  [<b8 d,> \times 2/3 {<b16 d, g,> d b]} \times 4/6 {[<b16 d, g,> d b
    <b16 d, g,> d b]} [<b8 d, g,> \times 2/3 {e16 d c]} \times 4/6 {[b c d c 
b a]} |
  }
}

remove "pdf.scm", "pdftex.scm" from lily.scm.

btw, we have the development release in CVS now. You can check the
sources out using

   cvs -d :pserver:anoncvs <at> lilypond.org:/home/lilypond login
   cvs -z3 -d :pserver:anoncvs <at> lilypond.org:/home/lilypond co lilypond

(This bug was fixed in CVS)

programming error: Rhythmic_req has no duration (Continuing; cross thumbs)

Hi,

I still get a bunch of programming errors in 1.4.12-1, debian package, and it 
still happens after upgrading to python2.2.

The errors occur right after 
Interpreting music...
and the subject line of this email is printed 12 times before lilypond exits 
with value 2.

I have found a new example which is small enough to attach. Could anyone who 
is using Debian's 1.4.12-1 try it and see if the same error occurs? Just 
untar the attachment and do "ly2dvi score".

A weird thing is that if I add a blank line after the end of 1-mand1.ly, 
everything suddenly works fine.

Erik

It's a quirky bug related to some kind of memory corruption or
lowlevel issue. We've never been able to pin it down.  As you might
have guessed, it doesn't happen on my machine.
