2.1.29 RhythmicStaff

A context like Staff but for printing rhythms. Pitches are ignored; the notes are printed on one line.

This context also accepts commands for the following context(s): Staff.

This context creates the following layout object(s): BarLine, DotColumn, InstrumentName, LedgerLineSpanner, StaffSpacing, StaffSymbol, TimeSignature and VerticalAxisGroup.

This context sets the following properties:

This is not a ‘Bottom’ context; search for such a one will commence after creating an implicit context of type Voice.

Context RhythmicStaff can contain CueVoice, NullVoice and Voice.

This context is built from the following engraver(s):

Axis_group_engraver

Group all objects created in this context in a VerticalAxisGroup spanner.

Properties (read)

currentCommandColumn (graphical (layout) object)

Grob that is X-parent to all current breakable items (clef, key signature, etc.).

hasAxisGroup (boolean)

True if the current context is contained in an axis group.

keepAliveInterfaces (list)

A list of symbols, signifying grob interfaces that are worth keeping a staff with remove-empty set around for.

Properties (write)

hasAxisGroup (boolean)

True if the current context is contained in an axis group.

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

Bar_engraver

Create barlines. This engraver is controlled through the whichBar property. If it has no bar line to create, it will forbid a linebreak at this point. This engraver is required to trigger the creation of clefs at the start of systems.

Music types accepted: ad-hoc-jump-event, coda-mark-event, dal-segno-event, fine-event, section-event, segno-mark-event and volta-span-event

measureBarType (string)

Bar line to insert at a measure boundary.

repeatCommands (list)

A list of commands related to volta-style repeats. In general, each element is a list, '(command args…), but a command with no arguments may be abbreviated to a symbol; e.g., '((start-repeat)) may be given as '(start-repeat).
