Adding the current date to a score

With a little Scheme code, the current date can easily be added to a score.

% first, define a variable to hold the formatted date:
date = #(strftime "%d-%m-%Y" (localtime (current-time)))
% use it in the title block:
\header {
 title = "Including the date!"
 subtitle = \date
}
\score {
 \relative c'' {
 c4 c c c
 }
}
% and use it in a \markup block:
\markup {
 \date
}

Aligning and centering instrument names

The horizontal alignment of instrument names is tweaked by changing the Staff.InstrumentName #'self-alignment-X property. The \layout variables indent and short-indent define the space in which the instrument names are aligned before the first and the following systems, respectively.

\paper { left-margin = 3\cm }
\score {
 \new StaffGroup <<
 \new Staff \with {
 \override InstrumentName.self-alignment-X = #LEFT
 instrumentName = \markup \left-column {
 "Left aligned"
 "instrument name"
 }
 shortInstrumentName = "Left"
 }
 { c''1 \break c''1 }
 \new Staff \with {
 \override InstrumentName.self-alignment-X = #CENTER
 instrumentName = \markup \center-column {
 Centered
 "instrument name"
 }
 shortInstrumentName = "Centered"
 }
 { g'1 g'1}
 \new Staff \with {
 \override InstrumentName.self-alignment-X = #RIGHT
 instrumentName = \markup \right-column {
 "Right aligned"
 "instrument name"
 }
 shortInstrumentName = "Right"
 }
 { e'1 e'1 }
 >>
 \layout {
 ragged-right = ##t
 indent = 4\cm
 short-indent = 2\cm
 }
}

Demonstrating all headers

All header fields with special meanings.

\header {
 copyright = "copyright"
 title = "title"
 subtitle = "subtitle"
 composer = "composer"
 arranger = "arranger"
 instrument = "instrument"
 metre = "metre"
 opus = "opus"
 piece = "piece"
 poet = "poet"
 texidoc = "All header fields with special meanings."
 copyright = "public domain"
 enteredby = "jcn"
 source = "urtext"
}
\layout {
 ragged-right = ##f
}
\score {
 \relative c'' { c1 | c | c | c }
}
\score {
 \relative c'' { c1 | c | c | c }
 \header {
 title = "localtitle"
 subtitle = "localsubtitle"
 composer = "localcomposer"
 arranger = "localarranger"
 instrument = "localinstrument"
 metre = "localmetre"
 opus = "localopus"
 piece = "localpiece"
 poet = "localpoet"
 copyright = "localcopyright"
 }
}

Outputting the version number

By putting the output of lilypond-version into a lyric, it is possible to print the version number of LilyPond in a score, or in a document generated with lilypond-book. Another possibility is to append the version number to the doc-string, in this manner:

\score {
 \new Lyrics {
 \override Score.RehearsalMark.self-alignment-X = #LEFT
 \mark #(string-append "Processed with LilyPond version " (lilypond-version))
 s2
 }
}
