Functions

func Add

func Add(s string, ancestors int) string

Add adds an ancestry reference to the given string.

func Parse

func Parse(s string) (string, int, error)

Parse parses s for git ancestry references. It supports special characters ^ ~, both of which are supported by git. Note in git ^ and ~ have different meanings on commits that have multiple parent commits. In Pachyderm there's only 1 parent possible so they have identical meanings. We support both simply for familiarity sake. In addition we support referencing the beginning of the branch with the . character. ParseAncestry returns the base reference and how many ancestors back to go. For example: foo^ -> foo, 1 foo^^ -> foo, 2 foo^3 -> foo, 3 foo.1 -> foo, -1 foo.3 -> foo, -3 (all examples apply with ~ in place of ^ as well

func SanitizeName

func SanitizeName(name string) string

SanitizeName forces a name to pass ValidateName, by replacing offending characters with _s

func ValidateName

func ValidateName(name string) error

ValidateName validates a name to make sure that it can be used unambiguously with Ancestry syntax.
