func SanitizeACIdentifier added in v1.1.0 

func SanitizeACIdentifier(s string) (string, error)

SanitizeACIdentifier replaces every invalid ACIdentifier character in s with an underscore making it a legal ACIdentifier string. If the character is an upper case letter it replaces it with its lower case. It also removes illegal edge characters (hyphens, period, underscore, tilde and slash).

This is a helper function and its algorithm is not part of the spec. It should not be called without the user explicitly asking for a suggestion.

func SanitizeACName 

func SanitizeACName(s string) (string, error)

SanitizeACName replaces every invalid ACName character in s with a dash making it a legal ACName string. If the character is an upper case letter it replaces it with its lower case. It also removes illegal edge characters (hyphens).

This is a helper function and its algorithm is not part of the spec. It should not be called without the user explicitly asking for a suggestion.

func ShortHash

Types

type ACIdentifier added in v1.1.0
