Hi LilyPonders,
I'm trying to automagically select pieces within a library.
My first intention was to use 'tags' but it does not seem to work a that
level.
So here's the idea: let say I include a full library in one file and I want
to get a book with some pre-selected pieces only, e.g.:
\version "2.19.28"
my-first-piece = {
\tag level-one {
\relative c' {
\mark "Level 1"
c1 d e f g a b c
}
}
}
my-second-piece = {
\tag level-one {
\relative c' {
\mark "Level 1"
c2 d e f g a b c
}
}
}
my-third-piece = {
\tag level-two {
\relative c' {
\mark "Level 2"
c4 d e f g a b c
}
}
}
my-fourth-piece = {
\tag level-two {
\relative c' {
\mark "Level 2"
c8 d e f g a b c
}
}
}
%% Full library included:
my-library = \book {
\score { \my-first-piece }
\score { \my-second-piece }
\score { \my-third-piece }
\score { \my-fourth-piece }
}
%% Select pieces by level:
\book {
\bookpart {
%% Select only 'level 1 pieces':
%\keepWithTag #'level-one {
\my-library
%}
\header {
title = "Level I"
}
}
\bookpart {
%% Select only 'level 2 pieces':
%\keepWithTag #'level-two {
\my-library
%}
\header {
title = "Level II"
}
}
}
Any idea how to achieve that ?
Cheers,
~Pierre
