A comment is a remark for the human reader of the music input; it is
ignored while parsing, so it has no effect on the printed output.
There are two types of comments. The percent symbol `%'
introduces a line comment; after % the rest of the line is
ignored. A block comment marks a whole section of music
input. Anything that is enclosed in %{ and %} is
ignored. The following fragment shows possible uses for comments
% notes for twinkle twinkle follow
c4 c g' g a a g2
%{
This line, and the notes below
are ignored, since they are in a
block comment.
g g f f e e d d c2
%}
There is a special statement that is a kind of comment. The \version
statement marks for which version of LilyPond the file was written.
To mark a file for version 2.6.0, use
\version "2.6.0"
These annotations make future upgrades of LilyPond go more
smoothly. Changes in the syntax are handled with a special program,
convert-ly (see Updating files with convert-ly), and it uses
\version to determine what rules to apply.
This page is for LilyPond-2.8.8 (stable-branch).
