Symbolic Macros and Rule Finalizers in Bazel Build System

Learn about symbolic macros and rule finalizers in this technical talk from Google engineers Susan Steinman and Alexandre Rostovtsev at a Linux Foundation event. Discover how symbolic macros provide well-structured, rule-like capabilities including typed attributes, documentation, and declared dependencies while working effectively with labels and selects(). Explore the implementation of these macros in your codebase and gain insights into rule finalizers - specialized symbolic macros that execute during the final package loading stage after all non-finalizer targets are defined, regardless of their position in BUILD files.
