| title: 'macro' |
| --- |
| |
| A callable Starlark value representing a symbolic macro; in other words, the return value of |
| [`macro()`](/versions/8.2.1/rules/lib/globals/bzl#macro). Invoking this value during package |
| construction time will instantiate the macro, and cause the macro's implementation function to be |
| evaluated (in a separate context, different from the context in which the macro value was invoked), |
| in most cases causing targets to be added to the package's target set. For more information, see |
| [Macros](https://bazel.build/versions/8.2.1/extending/macros). |
