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
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
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
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.
