2.2.68 Jump_engraver

This engraver creates instructions such as D.C. and Fine, placing them vertically outside the set of staves given in the stavesFound context property.

If Jump_engraver is added or moved to another context, Staff_collecting_engraver also needs to be there so that marks appear at the intended Y location.

Music types accepted: ad-hoc-jump-event, dal-segno-event and fine-event

Properties (read)

codaMarkCount (non-negative, exact integer)

Updated at the end of each timestep in which a coda mark appears: not set during the first timestep, 0 up to the first coda mark, 1 from the first to the second, 2 from the second to the third, etc.

codaMarkFormatter (procedure)

A procedure that creates a coda mark (which in conventional D.S. al Coda form indicates the start of the alternative endings), taking as arguments the mark sequence number and the context. It should return a markup object.

dalSegnoTextFormatter (procedure)

Format a jump instruction such as D.S.

The first argument is the context.

The second argument is the number of times the instruction is performed.

The third argument is a list of three markups: start-markup, end-markup, and next-markup.

If start-markup is #f, the form is da capo; otherwise the form is dal segno and start-markup is the sign at the start of the repeated section.

If end-markup is not #f, it is either the sign at the end of the main body of the repeat, or it is a Fine instruction. When it is a Fine instruction, next-markup is #f.

If next-markup is not #f, it is the mark to be jumped to after performing the body of the repeat, e.g., Coda.

finalFineTextVisibility (boolean)

Whether \fine at the written end of the music should create a Fine instruction.

fineText (markup)

The text to print at \fine.

segnoMarkCount (non-negative, exact integer)

Updated at the end of each timestep in which a segno appears: not set during the first timestep, 0 up to the first segno, 1 from the first to the second segno, 2 from the second to the third segno, etc.

segnoMarkFormatter (procedure)

A procedure that creates a segno (which conventionally indicates the start of a repeated section), taking as arguments the mark sequence number and the context. It should return a markup object.

stavesFound (list of grobs)

A list of all staff-symbols found.

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