E0109 error

Decorator not followed by a decoratable declaration

area: parsing (x01xx)
fails the build: yes

A decorator (@name or @name(…)) stands before a statement that can't be decorated, such as a call or an assignment. Decorators apply to declarations: functions, local, const, classes, class members, enums and the like. Put the decorator right before the declaration it is meant for.

Example

× failswowlua

@deprecatedprint("old API")

✓ compileswowlua

@deprecatedlocal function oldApi()    print("old API")end

The compiler reports it like this:

error[E0109]: a decorator must be followed by a declaration (function, local, const, class, …)
  ┌─ src/main.wowlua:1:1
