Skylib module containing functions for checking Bazel versions.

versions.check

versions.check(minimum_bazel_version, maximum_bazel_version, bazel_version)

Check that the version of Bazel is valid within the specified range.

PARAMETERS

Name	Description	Default Value
minimum_bazel_version	minimum version of Bazel expected	none
maximum_bazel_version	maximum version of Bazel expected	`None`
bazel_version	the version of Bazel to check. Used for testing, defaults to native.bazel_version	`None`

versions.get

versions.get()

Returns the current Bazel version

versions.is_at_least(threshold, version)

Check that a version is higher or equals to a threshold.

PARAMETERS

Name	Description	Default Value
threshold	the minimum version string	none
version	the version string to be compared to the threshold	none

RETURNS

True if version >= threshold.

versions.is_at_most(threshold, version)

Check that a version is lower or equals to a threshold.

PARAMETERS

Name	Description	Default Value
threshold	the maximum version string	none
version	the version string to be compared to the threshold	none

RETURNS

True if version <= threshold.

versions.parse(bazel_version)

Parses a version string into a 3-tuple of ints

int tuples can be compared directly using binary operators (<, >).

For a development build of Bazel, this returns an unspecified version tuple that compares higher than any released version.

PARAMETERS

Name	Description	Default Value
bazel_version	the Bazel version string	none

RETURNS

An int 3-tuple of a (major, minor, patch) version.
