3.1.1 Accidental

Accidental objects are created by: Accidental_engraver.

Standard settings:

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.

glyph-name (string):

accidental-interface::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.

glyph-name-alist (list):

'((0 . accidentals.natural) (-1/2 . accidentals.flat) (1/2 . accidentals.sharp) (1 . accidentals.doublesharp) (-1 . accidentals.flatflat) (3/4 . accidentals.sharp.slashslash.stemstemstem) (1/4 . accidentals.sharp.slashslash.stem) (-1/4 . accidentals.mirroredflat) (-3/4 . accidentals.mirroredflat.flat))

An alist of key-string pairs.

horizontal-skylines (pair of skylines):

#<unpure-pure-container #<primitive-procedure ly:accidental-interface::horizontal-skylines> >

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 #<primitive-procedure ly:grob::vertical-skylines-from-stencil> #<primitive-procedure ly:grob::pure-simple-vertical-skylines-from-extents> >

Two skylines, one above and one below this grob.

X-extent (pair of numbers):

ly:accidental-interface::width

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

Y-extent (pair of numbers):

#<unpure-pure-container #<primitive-procedure ly:accidental-interface::height> #<primitive-procedure ly:accidental-interface::pure-height> >

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, font-interface, grob-interface, inline-accidental-interface and item-interface.
