The Internals Reference documentation contains a lot of information about LilyPond, but even more information can be gathered from looking at the internal LilyPond files. To explore these, first find the directory appropriate to your system, as follows:
cd
-ing into this directory from the
Terminal, or control-clicking on the LilyPond application and
selecting ‘Show Package Contents’.
Within this directory the two interesting subdirectories are
Let's begin by looking at some files in ../ly/.
Open ../ly/property-init.ly in a text editor. The one
you normally use for .ly
files will be fine. This file
contains the definitions of all the standard LilyPond built-in
commands – like \stemUp
and \slurDotted
. You will
see that these are nothing more than definitions of variables
containing one or a group of \override
commands. For
example, /tieDotted
is defined to be:
tieDotted = { \override Tie #'dash-period = #0.75 \override Tie #'dash-fraction = #0.1 }
If you do not like the default values these built-in commands can be redefined easily, just like any other variable, at the head of your input file.
These are the most useful files to be found in ../ly/:
Filename | Contents
|
---|---|
../ly/engraver-init.ly | Definitions of engraver Contexts
|
../ly/paper-defaults.ly | Specifications of paper-related defaults
|
../ly/performer-init.ly | Definitions of performer Contexts
|
../ly/property-init.ly | Definitions of all common macros
|
Other settings (such as the definitions of markup commands) are
stored as .scm
(Scheme) files. The Scheme programming
language is used to provide a programmable interface into
LilyPond internal operation. Further explanation of these files
is currently outside the scope of this manual, as a knowledge of
the Scheme language is required. Users should be warned that
a substantial amount of technical knowledge or time is required
to understand Scheme and these files.
If you have this knowledge, the Scheme files which may be of interest are:
Filename | Contents
|
---|---|
../scm/auto-beam.scm | Sub-beaming defaults
|
../scm/define-grobs.scm | Default settings for grob properties
|
../scm/define-markup-commands.scm | Specify all markup commands
|
../scm/midi.scm | Default settings for MIDI output
|
../scm/output-lib.scm | Settings that affect appearance of frets, colors,
accidentals, bar lines, etc
|
../scm/parser-clef.scm | Definitions of supported clefs
|
../scm/script.scm | Default settings for articulations
|
