bazel-lib/docs/run_binary.md

Runs a binary as a build action. This rule does not require Bash (unlike native.genrule()).

This fork of bazel-skylib's run_binary adds directory output support and better makevar expansions.

Runs a binary as a build action.

This rule does not require Bash (unlike native.genrule).

PARAMETERS

Name	Description	Default Value
name	The target name	none
tool	The tool to run in the action. Must be the label of a *_binary rule of a rule that generates an executable file, or of a file that can be executed as a subprocess (e.g. an .exe or .bat file on Windows or a binary with executable permission on Linux). This label is available for $(location) expansion in args and env.	none
srcs	Additional inputs of the action. These labels are available for $(location) expansion in args and env.	[]
args	Command line arguments of the binary. Subject to $(location) and make variable expansions via expand_location and expand_make_vars.	[]
env	Environment variables of the action. Subject to $(location) and make variable expansions via expand_location and expand_make_vars.	{}
outs	Output files generated by the action. These labels are available for $(location) expansion in args and env. Output files cannot be nested within output directories in out_dirs.	[]
out_dirs	Output directories generated by the action. These labels are not available for $(location) expansion in args and env since they are not pre-declared labels created via attr.output_list(). Output directories are declared instead by ctx.actions.declare_directory. Output directories cannot be nested within other output directories in out_dirs.	[]
mnemonic	A one-word description of the action, for example, CppCompile or GoLink.	"RunBinary"
progress_message	Progress message to show to the user during the build, for example, "Compiling foo.cc to create foo.o". The message may contain %{label}, %{input}, or %{output} patterns, which are substituted with label string, first input, or output's path, respectively. Prefer to use patterns instead of static strings, because the former are more efficient.	None
execution_requirements	Information for scheduling the action. For example, execution_requirements = { "no-cache": "1", }, See https://docs.bazel.build/versions/main/be/common-definitions.html#common.tags for useful keys.	None
use_default_shell_env	Passed to the underlying ctx.actions.run. May introduce non-determinism when True; use with care! See e.g. https://github.com/bazelbuild/bazel/issues/4912 Refer to https://bazel.build/rules/lib/builtins/actions#run for more details.	False
stamp	Whether to include build status files as inputs to the tool. Possible values: - stamp = 0 (default): Never include build status files as inputs to the tool. This gives good build result caching. Most tools don't use the status files, so including them in --stamp builds makes those builds have many needless cache misses. (Note: this default is different from most rules with an integer-typed stamp attribute.) - stamp = 1: Always include build status files as inputs to the tool, even in --nostamp builds. This setting should be avoided, since it is non-deterministic. It potentially causes remote cache misses for the target and any downstream actions that depend on the result. - stamp = -1: Inclusion of build status files as inputs is controlled by the --[no]stamp flag. Stamped targets are not rebuilt unless their dependencies change. When stamping is enabled, an additional two environment variables will be set for the action: - BAZEL_STABLE_STATUS_FILE - BAZEL_VOLATILE_STATUS_FILE These files can be read and parsed by the action, for example to pass some values to a linker.	0
kwargs	Additional arguments	none
