Text and font improvements

• A new \bar-line markup command to print bar lines in text is now available.

  \markup {
    \override #'(word-space . 2)
      \line {
        Examples
        \fontsize #-5 \translate-scaled #'(0 . 2) {
          \bar-line ":|."
          \bar-line ".|:"
          \bar-line ";!S!;"
          \bar-line "]{|}["
        }
      }
  }
  

  

• The syntax for customizing text and music fonts has been changed. Instead of

  \paper {
    #(define fonts
       (set-global-fonts
         #:music "Name of music font"
         #:brace "Name of music brace font"
         #:roman "Name of serif font"
         #:sans "Name of sans-serif font"
         #:typewriter "Name of typewriter font"))
  }
  

  or

  \paper {
    #(define fonts
       (make-pango-font-tree
         "Name of serif font"
         "Name of sans-serif font"
         "Name of typewriter font"
         factor))
  }
  

  the new syntax is

  \paper {
    property-defaults.fonts.music = "Name of music font"
    property-defaults.fonts.serif = "Name of serif font"
    property-defaults.fonts.sans = "Name of sans-serif font"
    property-defaults.fonts.typewriter = "Name of typewriter font"
  }
  

  Unlike the previous syntax, the new syntax does not interfere with font sizes, which should be set separately using set-global-staff-size or layout-set-staff-size.

  There is no brace key in the fonts alist; braces glyphs now always default to the music font. However, it is still possible to override this by using an extra font family, as shown in this example (which requires the LilyJAZZ font):

  \layout {
    \context {
      \Score
      \override SystemStartBrace.fonts.music = "lilyjazz"
    }
  }
  
  \new PianoStaff <<
    \new Staff { c' }
    \new Staff { c' }
  >>
  
  \markup \override #'(fonts . ((music . "lilyjazz"))) \left-brace #20
  

  Because fonts is simply a property, it is possible to override it on a per-grob basis, e.g.,

  \layout {
    \override Score.SectionLabel.fonts.roman = "Custom font"
  }
  

  This is preferable over the already existing font-name property, since the latter makes commands such as \bold ineffective, instead requiring “Bold” to be included in the font-name string. Using fonts does not have such effects.

• The \lookup markup command can now only be used for braces; for other glyphs, use the \musicglyph command. Instead of \lookup, it is also generally recommended to use \left-brace.
• In markup, when a music font is used (such as for dynamic markings), a glyph absent from the music font was previously rendered in a normal text font. This is no longer the case; a warning about the missing glyph is output instead. In order to use a text font, use the \serif, \sans, or \typewriter markup commands. For example:

  dolceP =
  #(make-dynamic-script
    #{
      \markup {
        \serif \normal-weight dolce
        p
      }
    #})
  
  { c'\dolceP }
  

  

• Small caps are now achieved by overriding font-variant to small-caps instead of overriding font-shape to caps. Since font-shape is primarily for achieving italics, this change makes it possible to use small caps and italics at the same time.
• The font-series property is now more flexible and allows the specification of values such as semibold and light instead of only normal and bold.

  The medium value is now an intermediate value between normal and bold rather than an equivalent of normal. Accordingly, the \medium markup command has been renamed to \normal-weight.

• The new font-stretch property allows the selection of a condensed or expanded font.
• The text of a VoltaBracket grob, as set by \override Score.VoltaBracket.text = … or \set Score.repeatCommands = …, is no longer automatically typeset in a music font; use the \volta-number markup command on those parts that need to be. For example, convert

  \set Score.repeatCommands = #'((volta "2, 5"))
  

  to

  \set Score.repeatCommands =
    #`((volta ,#{ \markup {
                    \concat { \volta-number 2 , }
                    \volta-number 5 }
              #}))
  

• In markup, fingerings (\markup \finger) and bass figures (\markup \figured-bass) now get scaled along with normal text when using \fontsize.

  myText = \markup {
    The fingering \finger { 5-4 } for a \figured-bass { 7 "6\\" } …
  }
  
  \myText
  \markup\fontsize #6 \myText
  

  

  The previous behavior can be restored by setting the global variables legacy-figured-bass-markup-fontsize and legacy-finger-markup-fontsize to #t, respectively:

  #(set! legacy-figured-bass-markup-fontsize #t)
  #(set! legacy-finger-markup-fontsize #t)
  
  myText = \markup {
    The fingering \finger { 4-5 } for a \figured-bass { 5+ 6 } …
  }
  
  \myText
  \markup\fontsize #6 \myText
  

  

• For best clarity, the \roman markup command has been renamed to \serif. Likewise, to cancel a setting of the font-family property to sans or typewriter, it should now be set to serif, not roman.
• The \text markup command has been removed. Instead, the \serif, \sans, or \typewriter markup commands should be used. These commands used to set the font style only if a normal text font was used (not a musical font, such as for dynamics), but now they both set the font style and make a normal text font used.
• The font size used by the \volta-number markup command has been reduced to make it better fit with surrounding text. At the same time, the size for the volta bracket number (which uses \volta-number for formatting by default) has been increased by the opposite amount, thus compensating for the change in the normal use case.
• Some glyphs like ‘one’ or ‘accidentals.hufnagelM1’ in the Emmentaler font had overly large glyph bounding boxes due to a bug in the font production chain. This is fixed now; be warned, however, that you might experience typesetting differences because tighter bounding boxes often lead to tighter typesetting.
• New markup commands to print the textual representation of accidentals are added: \text-doubleflat, \text-flat, \text-natural, \text-sharp, \text-doublesharp and the general \text-accidental.

  \markuplist \override #'(padding . 1) \table #'(-1 -1 -1 -1 -1 -1) {
    "Accidentals for text:"
     \text-doubleflat \text-flat \text-natural \text-sharp
     \text-doublesharp
    "Accidentals for music:"
    \doubleflat \flat \natural \sharp \doublesharp
  }
  

  

• The \circle markup command now listens to a bbox property. If set to #t, the bounding box of its argument is used for the circle’s diameter.

  \markup {
    \circle {
      \center-column { "short" "short" "very very long" }
    }
    \override #'(bbox . #t) \circle {
      \center-column { "short" "short" "very very long" }
    }
  }
  

  

• The \tag command is now allowed in markup environments. New markup commands are added for filtering (\keep-with-tag and \remove-with-tag) and for inserting markups (\push-to-tag and \append-to-tag) in markup context or from music context (\pushToTagMarkup \appendToTagMarkup).

  test = \markup {
    \tag #'a a
    \tag #'b b
    c
  }
  
  music = \relative {
    c'^\test c c c
  }
  
  \keepWithTag #'a \music
  \removeWithTag #'a \music
  \pushToTagMarkup #'a push \music
  \appendToTagMarkup #'a append \music
  
  \markup { \keep-with-tag #'a \test }
  \markup { \remove-with-tag #'a \test }
  \markup { \push-to-tag #'a push \test }
  \markup { \append-to-tag #'a append \test }
  \markup { \keep-with-tag #'a \score { \music } }
