-@subsection File structure (introduction)
-
-A basic example of a lilypond input file is
-
-@example
-\version "2.9.13"
-\score @{
- @{ @} % this is a single music expression;
- % all the music goes in here.
- \header @{ @}
- \layout @{ @}
- \midi @{ @}
-@}
-@end example
-
-@noindent
-There are many variations of this basic pattern, but this
-example serves as a useful starting place.
-
-The major part of this manual is concerned with entering various
-forms of music in LilyPond. However, many music expressions are not
-valid input on their own, for example, a @code{.ly} file containing
-only a note
-@example
-c'4
-@end example
-
-@noindent
-will result in a parsing error. Instead, music should be inside other
-expressions, which may be put in a file by themselves. Such
-expressions are called toplevel expressions. The next section enumerates
-them all.

-@node Multiple scores in a book
-@subsection Multiple scores in a book
-
-@funindex \book
-@cindex movements, multiple
-
-A document may contain multiple pieces of music and texts. Examples
-of these are an etude book, or an orchestral part with multiple
-movements. Each movement is entered with a @code{\score} block,
-
-@example
-\score @{
- @var{..music..}
-@}
-@end example
-
-and texts are entered with a @code{\markup} block,
-
-@example
-\markup @{
- @var{..text..}
-@}
-@end example
-
-@funindex \book
-
-All the movements and texts which appear in the same @code{.ly} file
-will normally be typeset in the form of a single output file.
-
-@example
-\score @{
- @var{..}
-@}
-\markup @{
- @var{..}
-@}
-\score @{
- @var{..}
-@}
-@end example
-
-However, if you want multiple output files from the same @code{.ly}
-file, then you can add multiple @code{\book} blocks, where each such
-@code{\book} block will result in a separate output. If you do not
-specify any @code{\book} block in the file, LilyPond will implicitly
-treat the full file as a single @code{\book} block, see @ref{File
-structure}. One important exception is within lilypond-book documents,
-where you explicitly have to add a @code{\book} block, otherwise only
-the first @code{\score} or @code{\markup} will appear in the output.
-
-The header for each piece of music can be put inside the @code{\score}
-block. The @code{piece} name from the header will be printed before
-each movement. The title for the entire book can be put inside the
-@code{\book}, but if it is not present, the @code{\header} which is at
-the top of the file is inserted.
-
-@example
-\header @{
- title = "Eight miniatures"
- composer = "Igor Stravinsky"
-@}
-\score @{
- @dots{}
- \header @{ piece = "Romanze" @}
-@}
-\markup @{
- ..text of second verse..
-@}
-\markup @{
- ..text of third verse..
-@}
-\score @{
- @dots{}
- \header @{ piece = "Menuetto" @}
-@}
-@end example
-
-@node Extracting fragments of notation
-@subsection Extracting fragments of notation
-
-It is possible to quote small fragments of a large score directly from
-the output. This can be compared to clipping a piece of a paper score
-with scissors.
-
-This is done by definining the measures that need to be cut out
-separately. For example, including the following definition
-
-
-@verbatim
-\layout {
- clip-regions
- = #(list
- (cons
- (make-rhythmic-location 5 1 2)
- (make-rhythmic-location 7 3 4)))
-}
-@end verbatim
-
-@noindent
-will extract a fragment starting halfway the fifth measure, ending in
-the seventh measure. The meaning of @code{5 1 2} is: after a 1/2 note
-in measure 5, and @code{7 3 4} after 3 quarter notes in measure 7.
-
-More clip regions can be defined by adding more pairs of
-rhythmic-locations to the list.
-
-In order to use this feature, LilyPond must be invoked with
-@code{-dclip-systems}. The clips are output as EPS files, and are
-converted to PDF and PNG if these formats are switched on as well.

@node Including LilyPond files
@subsection Including LilyPond files
The line @code{\include "file.ly"} is equivalent to pasting the contents
of file.ly into the current file at the place where you have the
\include. For example, for a large project you might write separate files
-for each instrument part and create a ``full score'' file which brings
+for each instrument part and create a @q{full score} file which brings
together the individual instrument files.
The initialization of LilyPond is done in a number of files that are
finds.
Files placed in directory @file{PATH/TO/share/lilypond/VERSION/ly/} (where
-VERSION is in the form ``2.6.1'') are on the path and available to
+VERSION is in the form @q{2.6.1}) are on the path and available to
@code{\include}. Files in the
current working directory are available to \include, but a file of the same
name in LilyPond's installation takes precedence. Files are

The @code{\include} statement can use full path information, but with the Unix
-convention @code{"/"} rather than the DOS/Windows @code{"\"}. For example,
+convention @samp{/} rather than the DOS/Windows @samp{\}. For example,
if @file{stuff.ly} is located one directory higher than the current working
directory, use

+
+@funindex \tag
+@cindex tag
+The @code{\tag} command marks music expressions with a name. These
+tagged expressions can be filtered out later. With this mechanism it
+is possible to make different versions of the same music source.
+
+In the following example, we see two versions of a piece of music, one
+for the full score, and one with cue notes for the instrumental part
+
+@example
+c1
+<<
+ \tag #'part <<
+ R1 \\
+ @{
+ \set fontSize = #-1
+ c4_"cue" f2 g4 @}
+ >>
+ \tag #'score R1
+>>
+c1
+@end example
+
+The same can be applied to articulations, texts, etc.: they are
+made by prepending
+@example
+-\tag #@var{your-tag}
+@end example
+to an articulation, for example,
+@example
+c1-\tag #'part ^4
+@end example
+
+This defines a note with a conditional fingering indication.
+
+@cindex keepWithTag
+@cindex removeWithTag
+By applying the @code{\keepWithTag} and @code{\removeWithTag}
+commands, tagged expressions can be filtered. For example,
+@example
+<<
+ @var{the music}
+ \keepWithTag #'score @var{the music}
+ \keepWithTag #'part @var{the music}
+>>
+@end example
+would yield
+
+@lilypondfile[ragged-right,quote]{tag-filter.ly}
+
+The arguments of the @code{\tag} command should be a symbol
+(such as @code{#'score} or @code{#'part}), followed by a
+music expression. It is possible to put multiple tags on
+a piece of music with multiple @code{\tag} entries,
+
+@example
+ \tag #'original-part \tag #'transposed-part @dots{}

}
@end verbatim
+@node Reference to page numbers
+@subsection Reference to page numbers
+
+A particular place of a score can be marked using the @code{\label}
+command, either at top-level or inside music. This label can then be
+refered to in a markup, to get the number of the page where the marked
+point is placed, using the @code{\page-ref} markup command.
+
+@lilypond[verbatim,line-width=11.0\cm]
+\header { tagline = ##f }
+\book {
+ \label #'firstScore
+ \score {
+ {
+ c'1
+ \pageBreak \mark A \label #'markA
+ c'
+ }
+ }
+
+ \markup { The first score begins on page \page-ref #'firstScore "0" "?" }
+ \markup { Mark A is on page \page-ref #'markA "0" "?" }
+}
+@end lilypond
+
+The @code{\page-ref} markup command takes three arguments:
+@enumerate
+@item the label, a scheme symbol, eg. @code{#'firstScore};
+@item a markup that will be used as a gauge to estimate the dimensions
+of the markup;
+@item a markup that will be used in place of the page number if the label
+is not known;
+@end enumerate
+
+The reason why a gauge is needed is that, at the time markups are
+interpreted, the page breaking has not yet occured, so the page numbers
+are not yet known. To work around this issue, the actual markup
+interpretation is delayed to a later time; however, the dimensions of
+the markup have to be known before, so a gauge is used to decide these
+dimensions. If the book has between 10 and 99 pages, it may be "00",
+ie. a two digit number.

+@node Table of contents
+@subsection Table of contents
+A table of contents is included using the @code{\markuplines \table-of-contents}
+command. The elements which should appear in the table of contents are
+entered with the @code{\tocItem} command, which may be used either at
+top-level, or inside a music expression.
+@verbatim
+\markuplines \table-of-contents
+\pageBreak
+
+\tocItem \markup "First score"
+\score {

+ }
+}
+
+\tocItem \markup "Second score"
+\score {
+ {
+ e' % ...
+ }
+}
+@end verbatim
+
+The markups which are used to format the table of contents are defined
+in the @code{\paper} block. The default ones are @code{tocTitleMarkup},
+for formatting the title of the table, and @code{tocItemMarkup}, for
+formatting the toc elements, composed of the element title and page
+number. These variables may be changed by the user:
+
+@verbatim
+\paper {
+ %% Translate the toc title into French:
+ tocTitleMarkup = \markup \huge \column {
+ \fill-line { \null "Table des matières" \null }
+ \hspace #1
+ }
+ %% use larfer font size
+ tocItemMarkup = \markup \large \fill-line {
+ \fromproperty #'toc:text \fromproperty #'toc:page
+ }
+}
+@end verbatim
+
+Note how the toc element text and page number are refered to in
+the @code{tocItemMarkup} definition.
+
+New commands and markups may also be defined to build more elaborated
+table of contents:
+@itemize @bullet
+@item first, define a new markup variable in the @code{\paper} block
+@item then, define a music function which aims at adding a toc element
+using this markup paper variable.

+result in a metronome mark in the printed score, is shown in the example
+above. In this example the tempo of quarter notes is set to 72 beats per

+This kind of tempo
