LilyPond 学习手册: 5.1.3 Naming conventions of objects and properties

### 5.1.3 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.
