bazel syntax: don't use exceptions for control flow Previously, break, continue, and return were implemented by throwing and catching exceptions. Now, the Eval.exec methods return a token to indicate the continuation: one of PASS, BREAK, CONTINUE, or RETURN. In addition, the return value is saved in the Eval, which is good for only one function invocation. This is simpler (and slightly more efficient). Also: - FlowStatement now includes PASS too; PassStatement is gone. - ReturnException is gone, plus one EvalException constructor. PiperOrigin-RevId: 255882194
{Fast, Correct} - Choose two
Build and test software of any size, quickly and reliably.
Speed up your builds and tests: Bazel only rebuilds what is necessary. With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds.
One tool, multiple languages: Build and test Java, C++, Android, iOS, Go, and a wide variety of other language platforms. Bazel runs on Windows, macOS, and Linux.
Scalable: Bazel helps you scale your organization, codebase, and continuous integration solution. It handles codebases of any size, in multiple repositories or a huge monorepo.
Extensible to your needs: Easily add support for new languages and platforms with Bazel's familiar extension language. Share and re-use language rules written by the growing Bazel community.
