Hi list,
I’m not very happy about LilyPond’s ties and semi-ties. Some
problems/questions:
1. Is there any difference between LaissezVibrerTies and RepeatTies
except of the default head-direction? Or could one save redundant code
(including different grob names for basically the same thing etc.) here?
2. IMO LaissezVibrerTies are almost always too short. And there are only
very ugly hacks like http://lsr.di.unimi.it/LSR/Item?id=715 to change
the length; it would be nice to have a grob property 'length or
'minimum-length.
3. This is what annoys me most: Hacks like
http://lsr.di.unimi.it/LSR/Item?id=794 shouldn’t be necessary; instead,
LilyPond should be able to take input ~ at repeat alternatives and get
things right automagically. Or at least there should be easy-to-use
commands for ties from/to barlines so abusing \laissezVibrer and
\repeatTie isn’t necessary. Probably they should behave as if there was
a line break and then print only the needed half.
(4. Slurs at repeats aren’t really nice either …)
Some opinions on that? How easy would that be implemented?
Here some ideas for 3. and 4.
%%%%%%%%
\version "2.19.36"
% (approximately) desired output
\relative {
\tieDown \slurUp % for better readability
d'2( c~
\repeat volta 2 { c4 d) c( d~ }
\alternative {
{ d c) d( \afterGrace c\laissezVibrer { \once \hideNotes d) } }
{ \grace { \once \hideNotes c^( } d2\repeatTie c) }
}
}
% suggested input
%{
\relative {
\tieDown \slurUp % for better readability
d'2( c~
\repeat volta 2 { c4 d) c( d~ }
\alternative {
{ d c) d( c~ \stopTieAtBarline \stopSlurAtBarline }
{ \startTieAtBarline \startSlurAtBarline d2 c) }
}
}
%}
% alternative input: detect needed spanners automatically
%{
\relative {
\tieDown \slurUp % for better readability
d'2( c~
\repeat volta 2 { c4 d) c( d~ }
\alternative {
{ d c) d( c~ \stopSpannersAtBarline }
{ \startSpannersAtBarline d2 c) }
}
}
