5.1.2 Naming conventions of objects and properties

We met some object naming conventions previously, in Contexts and engravers. Here for reference is a list of the most common object and property types together with the conventions for naming them and a couple of examples of some real names. We have used ‘A’ to stand for any capitalized alphabetic character and ‘aaa’ to stand for any number of lower-case alphabetic characters. Other characters are used verbatim.

Object/property type	Naming convention	Examples
Contexts	Aaaa or AaaaAaaaAaaa	Staff, GrandStaff
Layout Objects	Aaaa or AaaaAaaaAaaa	Slur, NoteHead
Engravers	Aaaa_aaa_engraver	Clef_engraver, Note_heads_engraver
Interfaces	aaa-aaa-interface	grob-interface, break-aligned-interface
Context Properties	aaa or aaaAaaaAaaa	alignAboveContext, skipBars
Layout Object Properties	aaa or aaa-aaa-aaa	direction, beam-thickness

As we shall see shortly, the properties of different types of object are modified by different commands, so it is useful to be able to recognize the types of objects and properties from their names.
