Functions

func Go1PointX

func Go1PointX(version string) (int, bool)

Go1PointX returns the second number in a string that looks like a Go version, i.e. X in anything that starts with "go1.X".

func ParseReleaseBranch

func ParseReleaseBranch(branchName string) (major, minor int, ok bool)

ParseReleaseBranch parses the major-minor version pair from release-branch.goX or release-branch.goX.Y release branch names, and reports whether the release branch name is valid.

For example, "release-branch.go1" is parsed as version 1.0, and "release-branch.go1.2" is parsed as version 1.2.

func ParseTag

func ParseTag(tagName string) (major, minor, patch int, ok bool)

ParseTag parses the major-minor-patch version triplet from goX, goX.Y, or goX.Y.Z tag names, and reports whether the tag name is valid.

Tags with suffixes like "go1.2beta3" or "go1.2rc1" are currently not supported, and get rejected.

For example, "go1" is parsed as version 1.0.0, "go1.2" is parsed as version 1.2.0, and "go1.2.3" is parsed as version 1.2.3.
