tags on tweaks
Hi,
just to verify: I assume it is always necessary to tag a complete
music expression, or can just tweaks themselves get tagged?
Here is an example for a use case: In the score the dynamics should
get offset to the left to optimize vertical space requirements. In the
part the dynamics should be left at the default position. It would be
nice if just the tweak could get tagged in order to avoid the
verbosity of explicitely repeating the musical expression with
different tags applied.
This works:
- begin snippet
\version 2.19.5
music = { \clef G r4
\tag #'score { fis'''8 -\tweak X-offset #-2.5 \f [ }
\tag #'part { fis'''8 \f [ }
ees'' c' a''' ] r4 }
{ \keepWithTag #'score \music
\keepWithTag #'part \music }
- end snippet
This doesn't work:
- begin snippet
\version 2.19.5
music = { \clef G r4
fis'''8 \tag #'score -\tweak X-offset #-2.5 \f [
ees'' c' a''' ] r4 }
{ \keepWithTag #'score \music
\keepWithTag #'part \music }
end snippet

Hi Orm,
No particular remark on your topic except that you can use an easier syntax
:
%
\version 2.19.5
music = {
\clef G r4
\tag score { fis'''8 -\tweak X-offset #-2.5 \f [ }
\tag part { fis'''8 \f [ }
ees'' c' a''' ] r4
}
{
\keepWithTag score \music
\keepWithTag part \music
}
%
Cheers,
Pierre
PS: Strange that the doc does not show this synax.

You may insert the tag itself as a post-event using -\tag before the
tweak, yet the tag will then apply both to the tweak and the following
expression.
This gives you
%%%
\version 2.19
music = {
\clef G
r4 { fis'''8
-\tag score -\tweak X-offset #-2.5 \f
-\tag part \f [ }
ees'' c' a''' ] r4
}
{
\keepWithTag score \music
\keepWithTag part \music
}
Well, it's a bit shorter.
If there are many instances of the problem, you might wrap this into a
music function:
\version 2.19
%sctw = score tweak...
sctw = #(define-music-function
(parser location prop val mus)
(symbol? number? ly:music?)
#{ -\tag score -\tweak $prop $val $mus
-\tag part $mus #} )
music = {
\clef G
r4 fis'''8 -\sctw X-offset #-2.5 \f [ ees'' c' a''' ] r4
}
{
\keepWithTag score \music
\keepWithTag part \music
}
