3.1.1 Accidental

An accidental. Horizontal padding and configuration between accidentals is controlled by the AccidentalPlacement grob.

Accidental objects are created by: Accidental_engraver.

Standard settings:

after-line-breaking (boolean):

ly:accidental-interface::remove-tied

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

alteration (number):

accidental-interface::calc-alteration

Alteration numbers for accidental.

avoid-slur (symbol):

'inside

Method of handling slur collisions. Choices are inside, outside, around, and ignore. inside adjusts the slur if needed to keep the grob inside the slur. outside moves the grob vertically to the outside of the slur. around moves the grob vertically to the outside of the slur only if there is a collision. ignore does not move either. In grobs whose notational significance depends on vertical position (such as accidentals, clefs, etc.), outside and around behave like ignore.

extra-spacing-width (pair of numbers):
'(-0.2 . 0.0)

In the horizontal spacing problem, we pad each item by this amount (by adding the ‘car’ on the left side of the item and adding the ‘cdr’ on the right side of the item). In order to make a grob take up no horizontal space at all, set this to (+inf.0 . -inf.0).

glyph-name (string):

accidental-interface::calc-glyph-name

The glyph name within the font.

In the context of (span) bar lines, glyph-name represents a processed form of glyph, where decisions about line breaking, etc., are already taken.

horizontal-skylines (pair of skylines):

#<unpure-pure-container #<program 7fba2ad003c0 56287501a850> >

Two skylines, one to the left and one to the right of this grob.

stencil (stencil):

ly:accidental-interface::print

The symbol to print.

vertical-skylines (pair of skylines):

#<unpure-pure-container #<program 7fba2ade4cf0 56287502f7d0> #<program 7fba2ade4eb0 56287502f710> >

Two skylines, one above and one below this grob.

X-offset (number):

ly:grob::x-parent-positioning

The horizontal amount that this object is moved relative to its X-parent.

Y-extent (pair of numbers):

#<unpure-pure-container #<program 7fba2ad00350 56287501a880> >

Extent (size) in the Y direction, measured in staff-space units, relative to object’s reference point.

This object supports the following interface(s): accidental-interface, accidental-switch-interface, font-interface, grob-interface, inline-accidental-interface and item-interface.

This object is of class Item (characterized by item-interface).
