Produces a target that contains versioning information for an Apple bundle.

This rule allows version numbers to be hard-coded into the BUILD file or extracted from the build label passed into Bazel using the --embed_label command line flag.

Targets created by this rule do not generate outputs themselves, but instead should be used in the version attribute of an Apple application or extension bundle target to set the version keys in that bundle's Info.plist file.

Examples

# A version scheme that uses hard-coded versions checked into your
# BUILD files.
apple_bundle_version(
    name = "simple",
    build_version = "1.0.134",
    short_version_string = "1.0",
)

ios_application(
    name = "foo_app",
    ...,
    version = ":simple",
)

# A version scheme that parses version information out of the build
# label and uses a fallback for developers' builds. For example, the
# following command
#
#    bazel build //myapp:myapp --embed_label=MyApp_1.2_build_345
#
# would yield the Info.plist values:
#
#    CFBundleVersion = "1.2.345"
#    CFBundleShortVersionString = "1.2"
#
# and the development builds using the command:
#
#    bazel build //myapp:myapp
#
# would yield the values:
#
#    CFBundleVersion = "99.99.99"
#    CFBundleShortVersionString = "99.99"
#
apple_bundle_version(
    name = "build_label_version",
    build_label_pattern = "MyApp_{version}_build_{build}",
    build_version = "{version}.{build}",
    capture_groups = {
        "version": "\d+\.\d+",
        "build": "\d+",
    },
    short_version_string = "{version}",
    fallback_build_label = "MyApp_99.99_build_99",
)

ios_application(
    name = "bar_app",
    ...,
    version = ":build_label_version",
)

Provides: AppleBundleVersionInfo: Contains a reference to the JSON file that holds the version information for a bundle.

A unique name for this target.

A pattern that should contain placeholders inside curly braces (e.g., "foo_{version}_bar") that is used to parse the build label that is generated in the build info file with the --embed_label option passed to Bazel. Each of the placeholders is expected to match one of the keys in the capture_groups attribute.

A string that will be used as the value for the CFBundleVersion key in a depending bundle's Info.plist. If this string contains placeholders, then they will be replaced by strings captured out of build_label_pattern.

A dictionary where each key is the name of a placeholder found in build_label_pattern and the corresponding value is the regular expression that should match that placeholder. If this attribute is provided, then build_label_pattern must also be provided.

A build label to use when the no --embed_label was provided on the build. Used to provide a version that will be used during development.

A string that will be used as the value for the CFBundleShortVersionString key in a depending bundle's Info.plist. If this string contains placeholders, then they will be replaced by strings captured out of build_label_pattern. This attribute is optional; if it is omitted, then the value of build_version will be used for this key as well.
