Shell Rules

sh_binary

sh_binary(name, deps, srcs, data, args, compatible_with, deprecation, distribs, features, licenses, output_licenses, restricted_to, tags, testonly, toolchains, visibility)

The sh_binary rule is used to declare executable Bourne shell scripts. (sh_binary is a misnomer: its outputs aren't necessarily binaries.) This rule ensures that all dependencies are built, and appear in the runfiles area at execution time. We recommend that you name your sh_binary() rules after the name of the script minus the extension (e.g. .sh); do not give the rule and the file the same name.

Example

For a simple shell script with no dependencies and some data files:

sh_binary(
    name = "foo",
    srcs = ["foo.sh"],
    data = glob(["datafiles/*.txt"]),
)

Arguments

Attributes
name	Name; required A unique name for this target.
deps	List of labels; optional The list of "library" targets to be aggregated into this target. See general comments about deps at Attributes common to all build rules . This attribute should be used to list other sh_library rules that provide interpreted program source code depended on by the code in srcs. The files provided by these rules will be present among the runfiles of this target.
srcs	List of labels; required The file containing the shell script. This attribute must be a singleton list, whose element is the shell script. This script must be executable, and may be a source file or a generated file. All other files required at runtime (whether scripts or data) belong in the data attribute.
toolchains	List of labels; optional The set of toolchains that supply "Make variables" that this target can use in some of its attributes. Some rules have toolchains whose Make variables they can use by default.

sh_library

sh_library(name, deps, srcs, data, compatible_with, deprecation, distribs, features, licenses, restricted_to, tags, testonly, visibility)

The main use for this rule is to aggregate together a logical "library" consisting of related scripts—programs in an interpreted language that does not require compilation or linking, such as the Bourne shell—and any data those programs need at run-time. Such "libraries" can then be used from the data attribute of one or more sh_binary rules.

You can use the filegroup rule to aggregate data files.

In interpreted programming languages, there's not always a clear distinction between "code" and "data": after all, the program is just "data" from the interpreter's point of view. For this reason this rule has three attributes which are all essentially equivalent: srcs, deps and data. The current implementation does not distinguish between the elements of these lists. All three attributes accept rules, source files and generated files. It is however good practice to use the attributes for their usual purpose (as with other rules).

Examples

sh_library(
    name = "foo",
    data = [
        ":foo_service_script",  # an sh_binary with srcs
        ":deploy_foo",  # another sh_binary with srcs
    ],
)

Arguments

Attributes
name	Name; required A unique name for this target.
deps	List of labels; optional The list of "library" targets to be aggregated into this target. See general comments about deps at Attributes common to all build rules . This attribute should be used to list other sh_library rules that provide interpreted program source code depended on by the code in srcs. The files provided by these rules will be present among the runfiles of this target.
srcs	List of labels; optional The list of input files. This attribute should be used to list shell script source files that belong to this library. Scripts can load other scripts using the shell's source or . command.

sh_test

sh_test(name, deps, srcs, data, args, compatible_with, deprecation, distribs, features, flaky, licenses, local, restricted_to, shard_count, size, tags, testonly, timeout, toolchains, visibility)

A sh_test() rule creates a test written as a Bourne shell script.

See the attributes common to all test rules (*_test).

Examples

sh_test(
    name = "foo_integration_test",
    size = "small",
    srcs = ["foo_integration_test.sh"],
    deps = [":foo_sh_lib"],
    data = glob(["testdata/*.txt"]),
)

Arguments

Attributes
name	Name; required A unique name for this target.
deps	List of labels; optional The list of "library" targets to be aggregated into this target. See general comments about deps at Attributes common to all build rules . This attribute should be used to list other sh_library rules that provide interpreted program source code depended on by the code in srcs. The files provided by these rules will be present among the runfiles of this target.
srcs	List of labels; required The file containing the shell script. This attribute must be a singleton list, whose element is the shell script. This script must be executable, and may be a source file or a generated file. All other files required at runtime (whether scripts or data) belong in the data attribute.
toolchains	List of labels; optional The set of toolchains that supply "Make variables" that this target can use in some of its attributes. Some rules have toolchains whose Make variables they can use by default.
