Beam objects are created by: Auto_beam_engraver, Beam_engraver, Chord_tremolo_engraver and Grace_beam_engraver
Standard settings:
print-function
(procedure):Beam::print
Function taking grob as argument,
returning a Stencil
object.
gap
(dimension, in staff space):0.8
Size of a gap in a variable symbol.
positions
(pair):'(#f . #f)
Pair of staff coordinates (
left
.
right)
, where both left and right are in the
staff-space unit of the current staff.
thickness
(number):0.48
Bar line thickness, measured in
linethickness
.
before-line-breaking-callback
(procedure):Beam::before_line_breaking
This procedure is
called before line breaking, but after splitting breakable items at
potential line breaks.
neutral-direction
(direction):-1
Which direction to take in the
center of the staff.
dir-function
(procedure):beam-dir-majority-median
The function to determine the direction of a beam. Choices include:
beam-dir-majority
beam-dir-mean
beam-dir-median.
beamed-stem-shorten
(list):'(1.0 0.5 0.25)
How much to shorten beamed stems,
when their direction is forced. It is a list, since the value is different
depending on the number flags/beams.
flag-width-function
(procedure):beam-flag-width-function
Procedure that computes the width of a half-beam (a non-connecting beam.).
damping
(number):1
Amount of beam slope damping. 0: no, 1: yes,
100000: horizontal beams.
auto-knee-gap
(dimension, in staff space):5.5
If a gap is found between note heads
where a horizontal beam fits that is larger than this number, make a kneed beam.
font-family
(symbol):'roman
The font family is the broadest category for selecting text fonts. Options include: sans
, roman
space-function
(procedure):Beam::space_function
Calculate the vertical space between two beams. This function takes a beam grob and the maximum number of beams.
This object supports the following interfaces: spanner-interface, beam-interface, staff-symbol-referencer-interface and grob-interface
