2.2.19 Caesura_engraver

Notate a short break in sound that does not shorten the previous note.

Depending on the result of passing the value of caesuraType through caesuraTypeTransform, this engraver may create a BreathingSign with CaesuraScript grobs aligned to it, or it may create CaesuraScript grobs and align them to a BarLine.

If this engraver observes a BarLine, it calls caesuraTypeTransform again with the new information, and if necessary, recreates its grobs.

Music types accepted: caesura-event

Properties (read)

breathMarkDefinitions (list)

The description of breath marks. This is used by the Breathing_sign_engraver. See scm/breath.scm for more information.

caesuraType (list)

An alist

((bar-line . bar-type)
 (breath . breath-type)
 (scripts . script-type…)
 (underlying-bar-line . bar-type))

specifying which breath mark, bar line, and scripts to create at \caesura. All entries are optional.

bar-line has higher priority than a measure bar line and underlying-bar-line has lower priority than a measure bar line.

caesuraTypeTransform (procedure)

An engraver callback taking three arguments and returning an alist of the same kind as caesuraType.

The first argument is the context.

The second argument is the value of caesuraType with an additional entry (articulations . symbol-list) identifying the articulations attached to the caesura in the music. If the transform function returns this second argument unmodified, it is as if no transform function were set; the function is free to return a different value. The transform function can remove articulations, but any added articulations are ignored.

The third argument is a symbol-list identifying certain things the engraver has observed. bar-line indicates that the engraver has observed a BarLine at the current moment.

scriptDefinitions (list)

The description of scripts. This is used by the Script_engraver for typesetting note-superscripts and subscripts. See scm/script.scm for more information.

This engraver creates the following layout object(s): BreathingSign and CaesuraScript.
