3.1.116 SignumRepetitionis

SignumRepetitionis objects are created by: Signum_repetitionis_engraver.

Standard settings:

bar-extent (pair of numbers):

ly:bar-line::calc-bar-extent

The Y-extent of the actual bar line. This may differ from Y-extent because it does not include the dots in a repeat bar line.

break-align-anchor (number):

ly:bar-line::calc-anchor

Grobs aligned to this breakable item will have their X-offsets shifted by this number. In bar lines, for example, this is used to position grobs relative to the (visual) center of the bar line.

break-align-symbol (symbol):

'signum-repetitionis

This key is used for aligning, ordering, and spacing breakable items. See break-alignment-interface.

break-visibility (vector):

#(#t #t #f)

A vector of 3 booleans, #(end-of-line unbroken begin-of-line). #t means visible, #f means killed.

extra-spacing-height (pair of numbers):

pure-from-neighbor-interface::account-for-span-bar

In the horizontal spacing problem, we increase the height of each item by this amount (by adding the ‘car’ to the bottom of the item and adding the ‘cdr’ to the top of the item). In order to make a grob infinitely high (to prevent the horizontal spacing problem from placing any other grobs above or below this grob), set this to (-inf.0 . +inf.0).

gap (dimension, in staff space):

0.4

Size of a gap in a variable symbol.

glyph (string):

":|."

A string determining what ‘style’ of glyph is typeset. Valid choices depend on the function that is reading this property.

In combination with (span) bar lines, it is a string resembling the bar line appearance in ASCII form.

glyph-name (string):

#<procedure 5b68c690d640 at /build/out/share/lilypond/current/scm/lily/output-lib.scm:1472:0 (grob)>

The glyph name within the font.

In the context of (span) bar lines, glyph-name represents a processed form of glyph, where decisions about line breaking, etc., are already taken.

hair-thickness (number):

1.9

Thickness of the thin line in a bar line, expressed as a multiple of the default staff-line thickness (i.e., the visual output is not influenced by changes to Staff.StaffSymbol.thickness).

kern (dimension, in staff space):

3.0

The space between individual elements in any compound bar line, expressed as a multiple of the default staff-line thickness (i.e., the visual output is not influenced by changes to Staff.StaffSymbol.thickness).

layer (integer):

0

An integer which determines the order of printing objects. Objects with the lowest value of layer are drawn first, then objects with progressively higher values are drawn, so objects with higher values overwrite objects with lower values. By default most objects are assigned a layer value of 1.

non-musical (boolean):

#t

True if the grob belongs to a NonMusicalPaperColumn.

rounded (boolean):

#f

Decide whether lines should be drawn rounded or not.

segno-kern (number):

3.0

The space between the two thin lines of the segno bar line symbol, expressed as a multiple of the default staff-line thickness (i.e., the visual output is not influenced by changes to Staff.StaffSymbol.thickness).

space-alist (alist, with symbols as keys):

'((ambitus extra-space . 1.0)
  (time-signature extra-space . 0.75)
  (custos minimum-space . 2.0)
  (clef extra-space . 1.0)
  (key-signature extra-space . 1.0)
  (key-cancellation extra-space . 1.0)
  (first-note extra-space . 0.5)
  (next-note semi-fixed-space . 0.9)
  (signum-repetitionis extra-space . 0.5)
  (staff-bar extra-space . 0.5)
  (right-edge extra-space . 0.0))

An alist that specifies distances from this grob to other breakable items, using the format:

'((break-align-symbol . (spacing-style . space))
  (break-align-symbol . (spacing-style . space))
  ...)

Standard choices for break-align-symbol are listed in break-alignment-interface. Additionally, three special break-align symbols available to space-alist are:

first-note

used when the grob is just left of the first note on a line

next-note

used when the grob is just left of any other note; if not set, the value of first-note gets used

right-edge

used when the grob is the last item on the line (only compatible with the extra-space spacing style)

Choices for spacing-style are:

extra-space

Put this much space between the two grobs. The space is stretchable when paired with first-note or next-note; otherwise it is fixed.

minimum-space

Put at least this much space between the left sides of both grobs, without allowing them to collide. The space is stretchable when paired with first-note or next-note; otherwise it is fixed. Not compatible with right-edge.

fixed-space

Only compatible with first-note and next-note. Put this much fixed space between the grob and the note.

minimum-fixed-space

Only compatible with first-note and next-note. Put at least this much fixed space between the left side of the grob and the left side of the note, without allowing them to collide.

semi-fixed-space

Only compatible with first-note and next-note. Put this much space between the grob and the note, such that half of the space is fixed and half is stretchable.

Rules for this spacing are much more complicated than this. See [Wanske] page 126–134, [Ross] page 143–147.

stencil (stencil):

ly:bar-line::print

The symbol to print.

thick-thickness (number):

6.0

Thickness of the thick line in a bar line, expressed as a multiple of the default staff-line thickness (i.e., the visual output is not influenced by changes to Staff.StaffSymbol.thickness).

Y-extent (pair of numbers):

#<unpure-pure-container #<procedure ly:grob::stencil-height (_)> >

Extent (size) in the Y direction, measured in staff-space units, relative to object’s reference point.

This object supports the following interface(s): break-aligned-interface, font-interface, grob-interface, item-interface, pure-from-neighbor-interface and signum-repetitionis-interface.

This object is of class Item (characterized by item-interface).
