Identifiers
All of the information in a LilyPond input file, is internally represented as a Scheme value. In addition to normal Scheme data types (such as pair, number, boolean, etc.), LilyPond has a number of specialized data types,
- Input
- c++-function
- Music
- Identifier
- Translator_def
- Duration
- Pitch
- Score
- Music_output_def
- Moment (rational number)
LilyPond also includes some transient object types. Objects of these types are built during a LilyPond run, and do not `exist' per se within your input file. These objects are created as a result of your input file, so you can include commands in the input to manipulate them, during a lilypond run.
- Grob: short for Graphical object. See Grobs.
- Molecule: device-independent page output object, including dimensions. Produced by some Grob functions See Molecules
- Translator: object that produces audio objects or Grobs. This is not yet user accessible.
- Font_metric: object representing a font. (See Font metrics)
