Music types accepted: rest-event

Properties (read)

completionFactor (an exact rational or procedure)

When Completion_heads_engraver and Completion_rest_engraver need to split a note or rest with a scaled duration, such as c2*3, this specifies the scale factor to use for the newly-split notes and rests created by the engraver.

If #f, the completion engraver uses the scale-factor of each duration being split.

If set to a callback procedure, that procedure is called with the context of the completion engraver, and the duration to be split.

completionUnit (moment)

Sub-bar unit of completion.

measureLength (moment)

Length of one measure in the current time signature.

measurePosition (moment)

How much of the current measure have we had. This can be set manually to create incomplete measures.

middleCPosition (number)

The place of the middle C, measured in half staff-spaces. Usually determined by looking at middleCClefPosition and middleCOffset.

Properties (write)

restCompletionBusy (boolean)

Signal whether a completion-rest is active.

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