          def RunCommand.bool\_flag(
          name: str,
          /,
          \*,
          command: str,
          version: None | str = None
          ) -> None | bool
The tri-state of boolean `--name` for `command`: `True` for `--name` / `--name=true`, `False` for `--noname` / `--name=false`, `None` if unset. The caller owns the default when `None` (e.g. `--enable_bzlmod` defaults on for Bazel 7+). `function` **RunCommand.expand** 
        
          def RunCommand.expand(
          \*,
          command: str
          ) -> list
Expand all `--config=` flags for `command` into the fully-resolved flag list, compatible with `ctx.bazel.build(flags=...)`. Version-gated options are filtered to the run command's resolved Bazel version (same as `flag_value` / `resolve_for_command`), so the result reflects what Bazel actually receives — an option gated to a different version is dropped rather than reported as active. `function` **RunCommand.expand\_all** 
        
          def RunCommand.expand\_all(
          \*,
          command: str
          ) -> (list, list)
Expand `--config=` flags for `command`, split into `(startup_flags, flags)` where `common`-section options are rendered as `--default_override=0:common=...` startup-side entries. Like `expand`, the command flags are filtered to the resolved Bazel version so version-gated options report accurately. `function` **RunCommand.flag\_value** 
        
          def RunCommand.flag\_value(
          name: str,
          /,
          \*,
          command: str,
          version: None | str = None
          ) -> None | str
The effective value of `--name` for `command`, or `None` if unset. Last-write-wins over the config-expanded options; matches `--name=VALUE` and the two-token `--name VALUE` form. `version` overrides the Bazel version used for version-gated options. `function` **RunCommand.flag\_values** 
        
          def RunCommand.flag\_values(
          name: str,
          /,
          \*,
          command: str,
          version: None | str = None
          ) -> list
All values of a repeatable `--name` option for `command`, in order — for flags that legitimately accumulate (`--aspects`, `--output_groups`, …). `function` **RunCommand.merge** 
        
          def RunCommand.merge(
          other: bazel.RunCommand,
          /
          ) -> bazel.RunCommand
Overlay `other` on top of this run command, returning a new one. `other` wins on conflicts (its options apply after this one's under last-write-wins); startup flags, `--config` skip policy, and `version` are merged with `other` taking precedence when set. Neither input is mutated. `function` **RunCommand.options\_for** 
        
          def RunCommand.options\_for(
          \*,
          command: str
          ) -> list
Options applicable to `command` without expanding `--config=`. Each item is a `str` or a `(flag, version_condition)` tuple. `function` **RunCommand.sources** 
        
          def RunCommand.sources() -> list
The source file paths that were loaded. `function` **RunCommand.startup\_flags** 
        
          def RunCommand.startup\_flags() -> list
The startup flags Bazel runs with under this run command: the user startup flags + the rc-file `startup` section + `--ignore_all_rc_files`.
