Functions

func Replace

func Replace(s, old, new string, n int) string

Similar to strings.Replace except it starts from the right, immediately returns if s or old is the empty string, and n cannot be < 0 as there's no reason to replace from the right if you're going to replace everything.

Types

type Replacer

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

func NewReplacer

func NewReplacer(old, new string) *Replacer

Creates a new Replacer that can be used to repeatedly replace a single old-new pair. This implementation of Boyer-Moore is largely copied from the Go standard library.

func (*Replacer) Replace

func (rep *Replacer) Replace(s string, n int) string

Performs up to n replacements starting from the right.
