18 @chapter @command{lilypond-book}: Integrating text and music
20 If you want to add pictures of music to a document, you can simply do it
21 the way you would do with other types of pictures. The pictures are
22 created separately, yielding PostScript output or PNG images, and those
23 are included into a La@TeX{} or HTML document.
25 @command{lilypond-book} provides a way to automate this process: This
26 program extracts snippets of music from your document, runs
27 @command{lilypond} on them, and outputs the document with pictures
28 substituted for the music. The line width and font size definitions for
29 the music are adjusted to match the layout of your document.
31 This procedure may be applied to La@TeX{}, HTML or Texinfo documents.

51 Some texts contain music examples. These texts are musicological
52 treatises, songbooks, or manuals like this. Such texts can be made by
53 hand, simply by importing a PostScript figure into the word processor.
54 However, there is an automated procedure to reduce the amount of work
55 involved in HTML, La@TeX{}, and Texinfo documents.
57 A script called @code{lilypond-book} will extract the music fragments,
58 format them, and put back the resulting notation. Here we show a small
59 example for use with La@TeX{}. The example also contains explanatory
60 text, so we will not comment on it further.

220 @code{\lilypond@{@}}, so this command is only useful with the
221 @code{fragment} option.
223 The default linewidth of the music will be adjusted by examining the
224 commands in the document preamble, the part of the document before
225 @code{\begin@{document@}}. The @command{lilypond-book} command sends
226 these to La@TeX{} to find out how wide the text is. The line width for
227 the music fragments is then adjusted to the text width. Note that this
228 heuristic algorithm can fail easily; in such cases it is necessary to
229 use the @code{linewidth} music fragment option.

404 @node Music fragment options
405 @section Music fragment options
407 In the following, a ``LilyPond command'' refers to any command described
408 in the previous sections which is handled by @command{lilypond-book} to
409 produce a music snippet. For simplicity, LilyPond commands are only
410 shown in La@TeX{} syntax.
412 Note that the option string is parsed from left to right; if an option
413 occurs multiple times, the last one is taken.
415 The following options are available for LilyPond commands:
418 @item staffsize=@var{ht}
419 Set staff size to @var{ht}, which is measured in points.
422 Produce ragged-right lines with natural spacing (i.e., @code{raggedright
423 = ##t} is added to the LilyPond snippet). This is the default for the
424 @code{\lilypond@{@}} command if no @code{linewidth} option is present.
425 It is also the default for the @code{lilypond} environment if the
426 @code{fragment} option is set, and no line width is explicitly
430 Produce lines with packed spacing (i.e., @code{packed = ##t} is added
431 to the LilyPond snippet).
434 @itemx linewidth=@var{size}\@var{unit}
435 Set line width to @var{size}, using @var{unit} as units. @var{unit} is
436 one of the following strings: @code{cm}, @code{mm}, @code{in}, or
437 @code{pt}. This option affects LilyPond output (this is, the staff
438 length of the music snippet), not the text layout.
440 If used without an argument, set line width to a default value (as
441 computed with a heuristic algorithm).
443 If no @code{linewidth} option is given, @command{lilypond-book} tries to
444 guess a default for @code{lilypond} environments which don't use the
445 @code{raggedright} option.
448 Do not print the time signature.
451 Make @command{lilypond-book} add some boilerplate code so that you can
459 without @code{\layout}, @code{\score}, etc.
462 Don't add additional code to complete LilyPond code in music snippets.
463 Since this is the default, @code{nofragment} is redundant normally.
465 @item indent=@var{size}\@var{unit}
466 Set indentation of the first music system to @var{size}, using
467 @var{unit} as units. @var{unit} is one of the following strings:
468 @code{cm}, @code{mm}, @code{in}, or @code{pt}. This option affects
469 LilyPond, not the text layout.
472 Set indentation of the first music system to zero. This option affects
473 LilyPond, not the text layout. Since no indentation is the default,
474 @code{noindent} is redundant normally.
477 Reduce line length of a music snippet by @math{2*0.4}@dmn{in} and put
478 the output into a quotation block. The value `0.4@dmn{in}' can be
479 controlled with the @code{exampleindent} option.
482 Set the amount by which the @code{quote} option indents a music snippet.
485 @itemx relative=@var{n}
486 Use relative octave mode. By default, notes are specified relative to
487 middle@tie{}C. The optional integer argument specifies the octave of
488 the starting note, where the default @code{1} is middle C.
491 LilyPond also uses @command{lilypond-book} to produce its own
492 documentation. To do that, some more obscure music fragment options are
497 The argument of a LilyPond command is copied to the output file and
498 enclosed in a verbatim block, followed by any text given with the
499 @code{intertext} option (not implemented yet); then the actual music is
500 displayed. This option does not work well with @code{\lilypond@{@}} if
501 it is part of a paragraph.
504 (Only for Texinfo output.) If @command{lilypond} is called with the
505 @option{--header=@/texidoc} option, and the file to be processed is
506 called @file{foo@/.ly}, it creates a file @file{foo@/.texidoc} if there
507 is a @code{texidoc} field in the @code{\header}. The @code{texidoc}
508 option makes @command{lilypond-book} include such files, adding its
509 contents as a documentation block right before the music snippet.
511 Assuming the file @file{foo@/.ly} contains
515 texidoc = "This file demonstrates a single note."
521 and we have this in our Texinfo document @file{test.texinfo}

535 Most LilyPond test documents (in the @file{input} directory of the
536 distribution) are small @file{.ly} files which look exactly like this.
