Rules

• sh_binary
• sh_library
• sh_test

sh_binary

View rule source

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

The sh_binary rule is used to declare executable 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); the rule name and the file name must be distinct. sh_binary respects shebangs, so any available interpreter may be used (eg. #!/bin/zsh)

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; default is [] The list of "library" targets to be aggregated into this target. See general comments about deps at Typical attributes defined by most 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.

sh_library

View rule source

sh_library(name, deps, srcs, data, compatible_with, deprecation, distribs, exec_compatible_with, exec_properties, features, licenses, restricted_to, tags, target_compatible_with, 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; default is [] The list of "library" targets to be aggregated into this target. See general comments about deps at Typical attributes defined by most 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; default is [] 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

View rule source

sh_test(name, deps, srcs, data, args, compatible_with, deprecation, distribs, env, env_inherit, exec_compatible_with, exec_properties, features, flaky, licenses, local, restricted_to, shard_count, size, tags, target_compatible_with, 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; default is [] The list of "library" targets to be aggregated into this target. See general comments about deps at Typical attributes defined by most 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.
