2.2.34 Divisio_engraver

Create divisiones: chant notation for points of breathing or caesura.

Music types accepted: caesura-event, fine-event, section-event, volta-repeat-end-event and volta-repeat-start-event

Properties (read)

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.

This engraver creates the following layout object(s): Divisio.

Divisio_engraver is part of the following context(s) in \layout: GregorianTranscriptionStaff, InternalGregorianStaff and VaticanaStaff.
