Functions ¶

func Match ¶

func Match(raw, name string) bool

Match validates raw and matches name. It is intended for compiled policy values; malformed patterns fail closed.

Types ¶

type Pattern ¶

type Pattern struct {
	// contains filtered or unexported fields
}

Pattern is a validated, anchored hostname pattern. Dots are label separators: * and ? stay within one label, while ** is legal only as a complete label and crosses zero or more labels.

func Parse ¶

func Parse(raw string) (Pattern, error)

Parse validates raw against Epithet's deliberately small hostname-pattern language. In particular, it rejects the additional syntax understood by the doublestar matching engine so a dependency change cannot silently broaden a policy or inventory entry.

func (Pattern) Match ¶

func (p Pattern) Match(name string) bool

Match reports whether name matches the complete pattern. A slash is never a valid hostname label character here because it is the internal separator used to give doublestar DNS-label semantics.

func (Pattern) String ¶

func (p Pattern) String() string

String returns the pattern as authored.
