ChordNames

Typesets chord names. Can contain ChordNamesVoice contexts.

This context creates the following grobs: ChordName, SeparatingGroupSpanner, SeparationItem and VerticalAxisGroup.

This context sets the following properties:

• Set translator property verticalExtent to #f
• Set translator property extraVerticalExtent to #f
• Set translator property minimumVerticalExtent to #f

This context is a `bottom' context; it can not contain other contexts.

This context is built from the following engravers:

Engraver_group_engraver

A group of engravers taken together

Engraver_group_engraver is part of contexts: Voice, StaffGroup, PianoStaff, InnerStaffGroup, LyricsVoice, RhythmicStaff, NoteNames, TabVoice, FiguredBass, Thread, Staff, StaffContainer, ChordNames, GrandStaff, InnerChoirStaff, Lyrics, ChoirStaff and TabStaff

Skip_req_swallow_translator

Swallow requests of Skip_req type.

Skip_req_swallow_translator is part of contexts: Voice, LyricsVoice, TabVoice and ChordNames

Chord_name_engraver

Catch Note_req's, Tonic_reqs, Inversion_reqs, Bass_req and generate the appropriate chordname.

Properties (read)

chordChanges (boolean):

Only show changes in chords scheme?

Chord_name_engraver is part of contexts: ChordNames

Separating_line_group_engraver

Generates objects for computing spacing parameters.

This engraver creates the following grobs: SeparatingGroupSpanner and SeparationItem.

Separating_line_group_engraver is part of contexts: LyricsVoice, RhythmicStaff, NoteNames, Staff, ChordNames and TabStaff

Output_property_engraver

Interpret Music of Output_property type, and apply a function to any Graphic objects that satisfies the predicate.

Output_property_engraver is part of contexts: Voice, StaffGroup, InnerStaffGroup, RhythmicStaff, TabVoice, Thread, Staff, Score, ChordNames and TabStaff

Axis_group_engraver

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

Properties (read)

extraVerticalExtent (pair of numbers):

extra vertical extent, same format as MinimumVerticalExtent

minimumVerticalExtent (pair of numbers):

minimum vertical extent, same format as VerticalExtent

verticalExtent (pair of numbers):

hard coded vertical extent. The format is a pair of dimensions, for example, this sets the sizes of a staff to 10 (5+5) staffspaces high.

          property Staff.verticalExtent = #(-5.0 . 5.0)
          

VerticalExtent, MinimumVerticalExtent and ExtraVerticalExtent are predefined in all relevant contexts to #f, so they will not inherit values.

Note that these VerticalExtents can only operate on vertical groups, and therefore only work in contexts which contain an Axis_group_engraver.

Axis_group_engraver is part of contexts: LyricsVoice, RhythmicStaff, NoteNames, FiguredBass, Staff, StaffContainer, ChordNames, Lyrics and TabStaff
