Hi,
I beam lots of stuff manually. This leads to frequently setting
stemLeftBeamCount and stemRightBeamCount.
%%% BEGIN EX 1 %%%
\version "2.10.0"
\new Score {
c'64[
\set stemLeftBeamCount = #4
\set stemRightBeamCount = #2
c'64
\set stemLeftBeamCount = #2
\set stemRightBeamCount = #4
c'64
c'64]
}
%%% END EX 1 %%%
I've often wondered why there isn't some setting like
\set stemBeamCount = #'(4 . 2)
to set both stemLeftCount and stemRightBeamCount together.
However, following the third example in section 12.1.2 "Simple
substitution functions" produces the helper function below, with
cleaner code.
%%% BEGIN EX 2 %%%
\version "2.10.0"
beam = #(define-music-function (parser location left right) (number? number?)
#{
\set stemLeftBeamCount = #$left
\set stemRightBeamCount = #$right
#})
\new Score {
c'64[
\beam #4 #2
c'64
\beam #2 #4
c'64
c'64]
}
%%% END EX 2 %%%
Might help clean up someone else's code somewhere, too.
