| # Aliases | |
| An alias defines a local macro. | |
| A typical use case is to provide access to a shadowed field. | |
| Aliases are not members of a struct. They can be referred to only within the | |
| struct, and they do not appear in the output. | |
| <!-- CUE editor --> | |
| _alias.cue:_ | |
| ``` | |
| A = a // A is an alias for a | |
| a: { | |
| d: 3 | |
| } | |
| b: { | |
| a: { | |
| // A provides access to the outer "a" which would | |
| // otherwise be hidden by the inner one. | |
| c: A.d | |
| } | |
| } | |
| ``` | |
| <!-- result --> | |
| `$ cue eval alias.cue` | |
| ``` | |
| a: { | |
| d: 3 | |
| } | |
| b: { | |
| a: { | |
| c: 3 | |
| } | |
| } | |
| ``` |
