@unnumbered New features in 2.7 since 2.6
@ifhtml
This document is also available in @uref{NEWS.pdf,PDF}.
@end ifhtml
@itemize @bullet
@item LilyPond does no longer link to kpathsea for the @TeX{} backend.
This makes the @TeX{} backend more easily usable on various systems.
This fix was sponsored by Christian Ebert.
@item The horizontal location of rehearsal marks can be adjusted by
setting the @code{rehearsalMarkAlignSymbol} property,
@lilypond[raggedright]
\relative {
c1
\key cis \major
\clef alto
\set Score.rehearsalMarkAlignSymbol = #'key-signature
\mark "on-key"
cis
\key ces \major
\set Score.rehearsalMarkAlignSymbol = #'clef
\clef treble
\mark "on clef"
ces
}
@end lilypond
This feature was sponsored by Trevor Bača.
@item
It's now possible to easily create deeply nested system start
delimiters,
@lilypond[raggedright]
\new StaffGroup
\relative <<
\set StaffGroup.systemStartDelimiterHierarchy
= #'(SystemStartSquare (SystemStartBracket a (SystemStartSquare b)) d)
\new Staff { c1 }
\new Staff { c1 }
\new Staff { c1 }
\new Staff { c1 }
\new Staff { c1 }
>>
@end lilypond
In addition, there is now also support for ``square'' system start
brackets.
This feature was sponsored by Trevor Bača.
@item
Tie formatting now uses scoring. This opens the road to formatting
which handles complex situations require tradeoffs between different
beauty factors.
This refactoring has been sponsored by Steve Doonan.
@item
Each grob property may also be a ``grob closure.'' This means that it
is possible to combine functions. For example, the @code{Y-offset} of
a @code{InstrumentName} grob is defined to be
@verbatim
,(ly:make-simple-closure
`(,+
,(ly:make-simple-closure
(,Self_alignment_interface::y_aligned_on_self))
,(ly:make-simple-closure
(,Side_position_interface::y_aligned_on_support_refpoints)))
@end verbatim
@noindent
During execution, the @code{Y-offset} of an @code{InstrumentName} is computed
as
@example
(+ (Self_alignment_interface::y_aligned_on_self @var{grob})
(Self_alignment_interface::y_aligned_on_support_refpoints @var{grob}))
@end example
@item
Calculation of extent and offset of grob is now controlled via the
@code{X-extent}, @code{Y-extent}, @code{X-offset} and @code{Y-offset}
properties, for example
@verbatim
\override TextScript #'Y-offset = #-6
@end verbatim
@noindent
hard codes @code{TextScript} grobs to be 6 spaces below their Y-parent
grobs.
@item
Each grob property can be a procedure. If this is the case, it is
assumed to be a routine that calculates said property. This is a
major internal cleanup, which also provides advanced tweakability for
power users. For example,
@verbatim
\override Beam #'direction
= #(lambda (grob)
(if (> 4 (ly:grob-array-length (ly:grob-object grob 'stems)))
DOWN
UP))
@end verbatim
@noindent
With this code fragment, the direction of a beam is decided to be up
or down, depending on the number of stems in the beam.
@item
Support for figured bass has been rewritten. Now it supports
continuation lines, slashed figures, and its figures, brackets, and alignments may
tuned separately.
@lilypond[raggedright,fragment]
<<
\relative { c4 c c c }
\figures {
\set useBassFigureExtenders = ##t
<6+ 4 3> <6 4 3> <4 3+> <5/ 7/\+>
} >>
@end lilypond
This rewrite was sponsored by Trent Johnston and John Mandereau.
@item
Subproperties, like the @code{details} field of @code{Slur} and
@code{Tie} may now be tuned with @code{\override}. For example,
@verbatim
\override Stem #'details #'beamed-lengths = #'(4 4 3)
@end verbatim
@noindent
shortens the stems in beams.
@item
The default paper size may now be set from the command line using
@code{-dpaper-size}.
@item
Beamlets may stick out of the side of beams.
@lilypond[fragment,raggedright,relative=2]
{
\override Beam #'break-overshoot = #'(-0.5 . 0.5)
\set stemLeftBeamCount = #2
c8[
c16
\set stemRightBeamCount = #3
c ]
}
@end lilypond
This feature was sponsored by Trevor Bača.
@item
Vertical alignments of staves can now be tuned easily for individual
systems.
@lilypond[raggedright]
#(set-global-staff-size 13)
\relative c'' <<
\new PianoStaff <<
\new Voice {
c1
\overrideProperty
#"Score.NonMusicalPaperColumn"
#'line-break-system-details
#'((fixed-alignment-extra-space . 15))
c
}
{
c1\break
c\break
}
>>
>>
@end lilypond
This feature was sponsored by Nicolas Sceaux.
@item
Vertical spacing for page layout can now be tuned for each system
individually. The dimensions that can be tuned can be visualized.
@lilypond[verbatim]
#(set-default-paper-size "a7" 'landscape)
\book {
\score { { c4 } }
\paper { annotatespacing = ##t }
}
@end lilypond
These features were sponsored by Trevor Bača and Nicolas Sceaux.
@item
The slope of a stem-tremolo may be set manually
@lilypond[fragment,relative=1,raggedright]
c8:16[
\once \override StemTremolo #'slope = #0.45
c:16 c:16 c:16 ]
@end lilypond
This feature was sponsored by Sven Axelsson.
@item
Laissez vibrer ties can be created with @code{\laissezVibrer},
@lilypond[fragment,raggedright,relative=1]
\laissezVibrer r \laissezVibrer
@end lilypond
This feature was sponsored by Henrik Frisk.
@item
The order of words in @code{\markup} commands may now be reversed by
setting the @code{text-direction} property. This is useful for
Right-to-Left languages like Hebrew.
This feature was sponsored by Aaron Mehl.
@item
Texts over multi measure rests can stretch the corresponding measure,
if the appropriate @code{spring-and-rods} callback is set.
@lilypond[relative=2,fragment,raggedright]
\override MultiMeasureRestText #'springs-and-rods
= #Multi_measure_rest::set_text_rods
c1 R1 R1^"Very long long long text"
@end lilypond
This feature was sponsored by Kris Shaffer.
@item @textanchor{tie-chords}
Formatting of ties in chords has been improved. Ties no longer collide
with note heads and stems. In addition, it is possible to manually
specify tie formatting
@lilypond[relative=2, fragment,raggedright]
~
\override TieColumn #'tie-configuration =
#'((0 . -1) (2 . -1) (5.5 . 1) (7 . 1))
~
@end lilypond
This improvement has been sponsored by Bertalan Fodor, Jay Hamilton,
Kieren MacMillan, Steve Doonan, Trevor Bača, and Vicente Solsona
Dell¡.
@item
Formatting of isolated, single ties has been improved. Now, ties avoid
staff lines, flags and dots, without compromising their shape.
@lilypond[fragment,raggedright]
\relative c'' {
\stemUp
c16 c2...~ c16 ~ c2... |
c4~c8 c8~c16 c16~c32 c16.~[ c64]~ c64[ c8..] |
}
@end lilypond
This improvement has been sponsored by Bertalan Fodor, Jay Hamilton,
Kieren MacMillan, Steve Doonan, Trevor Bača, and Vicente Solsona
Dell¡.
@item @textanchor{repeat-counter}
With the @code{countPercentRepeats} property,
percent repeats get incremental numbers to indicate the accumulated repeat count.
@lilypond[relative=2,fragment,raggedright]
\set countPercentRepeats = ##t
\repeat percent 4 { c1 }
\time 2/4
\repeat percent 4 { c2 c2 }
@end lilypond
This feature was sponsored by Yoshinobu Ishizaki
@item
Text scripts such as fingering instructions and dynamics avoid
collisions with slurs
@lilypond[fragment,relative=1]
{
b_1( f'_1_2_3 c_3_4_5 a)
b( f'\p b,)
c-2_\markup { \italic {"cresc."}} ( f_\markup {x} c)
}
@end lilypond
@item
Tuplets can be made to reach the next non-tuplet note by setting the
@code{tupletFullLength} property,
@lilypond[fragment,relative=2]
\new Voice \with {
\remove Forbid_line_break_engraver
allowBeamBreak = ##t
}
{
\set Score.proportionalNotationDuration = #(ly:make-moment 1 32)
\set tupletFullLength = ##t
\times 2/3 { c8[ c c] }
c4
}
@end lilypond
This feature was sponsored by Trevor Bača.
@item
When @code{strict-note-spacing} is set, notes are spaced without regard
for clefs, bar lines, and grace notes. For example,
@lilypond[fragment,relative=2]
\override Score.SpacingSpanner #'strict-note-spacing = ##t
\new Staff { c8[ c \clef alto c \grace { c16[ c] } c8 c c] c32[ c32] }
@end lilypond
This feature was sponsored by Trevor Bača.
@item
Beams support the @code{break-overshoot} property, for example
@lilypond[relative=2,fragment]
\set allowBeamBreak = ##t
\override Beam #'break-overshoot = #'(1.0 . 2.0)
c2.. c8[ \break c]
@end lilypond
This feature was sponsored by Trevor Bača.
@item
Proportional notation is supported. Notes can be spaced proportional
to their time-difference by assigning a duration to
@code{proportionalNotationDuration}. For example,
@lilypond[relative=2,fragment,raggedright]
<<
\set Score.proportionalNotationDuration = #(ly:make-moment 1 16)
\new Staff { c8[ c c c c c] c4 c2 r2 }
\new Staff { c2 \times 2/3 { c8 c c } c4 c1 }
>>
@end lilypond
This feature was sponsored by Trevor Bača.
@item
Symbol sizes (e.g. accidentals) are disregarded for spacing if
@code{uniform-stretching} of the @code{SpacingSpanner} grob is set,
@lilypond[relative=2,fragment]
<<
\override Score.SpacingSpanner #'uniform-stretching = ##t
\new Staff { c16[ c c c c c c c c c16] }
\new Staff {
\times 6/7 { c16 c c cis c c c }
c8[ c32 c32 c16]
}
>>
@end lilypond
This feature was sponsored by Trevor Bača.
@item
Endings of broken tuplet brackets can be tuned. For example, you can
add arrows to the brackets,
@lilypond[fragment,raggedright,relative=2]
\override TupletBracket
#'edge-text = #(cons
(markup #:arrow-head X LEFT #f)
(markup #:arrow-head X RIGHT #f))
\times 4/5 {
c c c \bar "empty" \break c c
}
@end lilypond
This feature was sponsored by Trevor Bača.
@item @textanchor{arrow-glyph}
Arrow heads were added to the Feta font.
@lilypond[]
\lyrics {
\markup {
filled, to the right: \hspace #2.0 \fontsize #6 \arrow-head #0 #1 ##t
open, down: \hspace #2.0 \fontsize #6 \arrow-head #1 #-1 ##f
}
}
@end lilypond
These glyphs have been sponsored by Trevor Bača.
@item
Nested tuplets are automatically positioned,
@lilypond[fragment,raggedright,relative=2]
\set tupletNumberFormatFunction = #fraction-tuplet-formatter
\times 4/6 {
a4 a
\times 3/5 { a a a a a }
}
@end lilypond
This feature was sponsored by Trevor Bača.
@item
Music expressions can be displayed, in LilyPond notation, using the
new @code{\displayLilyMusic} function. For instance:
@verbatim
\displayLilyMusic \transpose c a, { c d e f }
@end verbatim
will print:
@verbatim
{ a, b, cis d }
@end verbatim
This feature was contributed by Nicolas Sceaux.
@item
The current bar number may be checked with @code{\barNumberCheck}, eg.
@verbatim
\barNumberCheck #22
@end verbatim
@noindent
will print a warning if it doesn't happen in measure 22.
@item
If @code{showLastLength} is set, only the last few measures of a piece
are rendered, which speeds up correcting scores. For example, setting
@verbatim
showLastLength = R1*5
\score { ... }
@end verbatim
@noindent
will render only the last five measures (assuming 4/4 time signature)
of a piece.
@item @textanchor{simple-melismata}
Melismata can be specified simply in the lyrics now, eg.
@lilypond[relative=1,verbatim,fragment]
{
c d( e) f e d
} \addlyrics {
Ky -- _ _ ri e
}
@end lilypond
This feature was sponsored by Nancho Alvarez
@item
Suggested accidentals (for notating musica ficta) may be switched on
with @code{suggestAccidentals}
@lilypond[verbatim,fragment,relative=2]
\set suggestAccidentals = ##t
ais bis
@end lilypond
This feature was sponsored by Nancho Alvarez.
@item
The setting @code{whichBar} and time-bookkeeping is now split into a
@code{Default_bar_line_engraver} and @code{Timing_translator}
respectively.
@item @textanchor{pitched-trill}
Explicit pitches may be added to trills,
@lilypond[relative,verbatim,fragment]
\pitchedTrill c4\startTrillSpan fis f\stopTrillSpan
@end lilypond
This feature was sponsored by D. Josiah Boothby and Jamie Bullock
@item
Markup now supports formatting of text paragraphs, using
@code{\wordwrap} and @code{\justify}.
This feature was sponsored by Sven Axelsson.
