Parse and load starlark-defined options in full package-path form. This includes the the following features available to native options parsing: * --(no)boolean_flag syntax * --flag=value syntax * --flag value syntax * single-dash syntax * for multiple values of same option, last option wins * internal-only options are treated like they don't exist There is potential here to combine some of the code in StarlarkOptionsParser.java with OptionsParserImpl.java since they support the same formats of flags. This is complicated by the fact that for native flags, you have a lot of information (type, internal vs external) before parsing whereas for starlark flags, you need to parse out the name first and load it to get this information. So I haven't done the combining in this CL. This brings up an interesting point that now all commands that use starlark flags will need to do loading. For now we limit starlark parsing to commands that already do building (which is possibly all the commands we care about). This behavior is still guarded behind --experimental_build_setting_api Work towards #5574 and #5577 PiperOrigin-RevId: 223600443
{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.
