3.1.50 DynamicTextSpanner

Dynamic text like ‘cresc’, usually followed by a (dashed) line. See also DynamicLineSpanner and TextSpanner.

DynamicTextSpanner objects are created by: Dynamic_engraver.

Standard settings:

before-line-breaking (boolean):


Dummy property, used to trigger a callback function.

bound-details (alist, with symbols as keys):
'((right (attach-dir . -1) (padding . 0.75))
  (right-broken (attach-dir . 1) (padding . 0.0))
  (left (attach-dir . -1)
        (stencil-offset -0.75 . -0.5)
        (padding . 0.75))
  (left-broken (attach-dir . 1)))

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

dash-fraction (number):


Size of the dashes, relative to dash-period. Should be between 0.1 and 1.0 (continuous line). If set to 0.0, a dotted line is produced

dash-period (number):


The length of one dash together with whitespace. If negative, no line is drawn at all.

font-shape (symbol):


Select the shape of a font. Choices include upright, italic, caps.

font-size (number):


The font size, compared to the ‘normal’ size. 0 is style-sheet’s normal size, -1 is smaller, +1 is bigger. Each step of 1 is approximately 12% larger; 6 steps are exactly a factor 2 larger. If the context property fontSize is set, its value is added to this before the glyph is printed. Fractional values are allowed.

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


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

minimum-length (dimension, in staff space):


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-Y-extent (pair of numbers):
'(-1 . 1)

Minimum size of an object in Y dimension, measured in staff-space units.

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


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

skyline-horizontal-padding (number):


For determining the vertical distance between two staves, it is possible to have a configuration which would result in a tight interleaving of grobs from the top staff and the bottom staff. The larger this parameter is, the farther apart the staves are placed in such a configuration.

springs-and-rods (boolean):


Dummy variable for triggering spacing routines.

stencil (stencil):


The symbol to print.

style (symbol):


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

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.

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

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