3.1.47 DurationLine

A horizontal duration line, continuing rhythmic items (usually note heads).

DurationLine objects are created by: Duration_line_engraver.

Standard settings:

after-line-breaking (boolean):

ly:spanner::kill-zero-spanned-time

Dummy property, used to trigger callback for after-line-breaking.

arrow-length (number):

2

Arrow length.

arrow-width (number):

1.5

Arrow width.

bound-details (alist, with symbols as keys):
'((right (attach-dir . -1)
         (end-on-accidental . #t)
         (end-on-arpeggio . #t)
         (padding . 0.4)
         (end-style . #f))
  (right-broken (padding . 0.4) (end-style . #f))
  (left-broken (padding . 0.5))
  (left (attach-dir . 1)
        (padding . -0.3)
        (start-at-dot . #f)))

An alist of properties for determining attachments of spanners to edges.

breakable (boolean):

#t

Allow breaks here.

details (alist, with symbols as keys):
'((hook-height . 0.34)
  (hook-thickness . #f)
  (hook-direction . 1)
  (extra-dot-padding . 0.5))

Alist of parameters for detailed grob behavior. More information on the allowed parameters for a grob can be found by looking at the top of the Internals Reference page for each interface having a details property.

left-bound-info (alist, with symbols as keys):

ly:horizontal-line-spanner::calc-left-bound-info

An alist of properties for determining attachments of spanners to edges.

minimum-length (dimension, in staff space):

2

Try to make a spanner at least this long, normally in the horizontal direction. This requires an appropriate callback for the springs-and-rods property. If added to a Tie, this sets the minimum distance between noteheads.

minimum-length-after-break (dimension, in staff space):

6

If set, try to make a broken spanner starting a line this long. This requires an appropriate callback for the springs-and-rods property. If added to a Tie, this sets the minimum distance to the notehead.

right-bound-info (alist, with symbols as keys):

ly:horizontal-line-spanner::calc-right-bound-info

An alist of properties for determining attachments of spanners to edges.

springs-and-rods (boolean):

ly:spanner::set-spacing-rods

Dummy variable for triggering spacing routines.

stencil (stencil):

duration-line::print

The symbol to print.

style (symbol):

'beam

This setting determines in what style a grob is typeset. Valid choices depend on the stencil callback reading this property.

thickness (number):

4

For grobs made up of lines, this is the thickness of the line. For slurs and ties, this is the distance between the two arcs of the curve’s outline at its thickest point, not counting the diameter of the virtual “pen” that draws the arcs. This property is expressed as a multiple of the current staff-line thickness (i.e., the visual output is influenced by changes to Staff.StaffSymbol.thickness).

to-barline (boolean):

#f

If true, the spanner will stop at the bar line just before it would otherwise stop.

vertical-skylines (pair of skylines):

#<unpure-pure-container #<procedure ly:grob::vertical-skylines-from-stencil (_)> #<procedure ly:grob::pure-simple-vertical-skylines-from-extents (_ _ _)> >

Two skylines, one above and one below this grob.

Y-offset (number):

0

The vertical amount that this object is moved relative to its Y-parent.

zigzag-length (dimension, in staff space):

1

The length of the lines of a zigzag, relative to zigzag-width. A value of 1 gives 60-degree zigzags.

zigzag-width (dimension, in staff space):

1

The width of one zigzag squiggle. This number is adjusted slightly so that the spanner line can be constructed from a whole number of squiggles.

This object supports the following interface(s): duration-line-interface, font-interface, grob-interface, horizontal-line-spanner-interface, line-interface, line-spanner-interface, spanner-interface and unbreakable-spanner-interface.

This object is of class Spanner (characterized by spanner-interface).
