Functions

func Chain

func Chain(r io.Reader, tt ...transform.Transformer) io.Reader

Chain returns a reader which applies all provided transformers.

func ReplaceText

func ReplaceText(cmd *cobra.Command)

Types

type RegexpTransformer

type RegexpTransformer struct {
	// MaxMatchSize is the maximum size of a regexp match.
	// If a match exceeds this limit, it may be omitted.
	// (Default is 2kb).
	MaxMatchSize int
	// contains filtered or unexported fields
}

RegexpTransformer replaces regexp matches in a stream See: http://golang.org/x/text/transform Note: this Transformer is not safe for concurrent use.

func Regexp

func Regexp(re *regexp.Regexp, new []byte) *RegexpTransformer

Regexp returns a transformer that replaces all matches of re with new

func RegexpFunc

func RegexpFunc(re *regexp.Regexp, replace func([]byte) []byte) *RegexpTransformer

RegexpFunc returns a transformer that replaces all matches of re with the result of calling replace with the match. The []byte parameter passed to replace should not be modified and is not guaranteed to be valid after the function returns.

func RegexpIndexFunc

func RegexpIndexFunc(re *regexp.Regexp, replace func(src []byte, index []int) []byte) *RegexpTransformer

RegexpIndexFunc returns a transformer that replaces all matches of re with the return value of replace. The replace function recieves the underlying src buffer and indexes into that buffer. The []byte parameter passed to replace should not be modified and is not guaranteed to be valid after the function returns.

func RegexpString

func RegexpString(re *regexp.Regexp, template string) *RegexpTransformer

RegexpString returns a transformer that replaces all matches of re with template Inside template, $ signs are interpreted as in Expand, so for instance $1 represents the text of the first submatch.

func RegexpStringFunc

func RegexpStringFunc(re *regexp.Regexp, replace func(string) string) *RegexpTransformer

RegexpStringFunc returns a transformer that replaces all matches of re with the result of calling replace with the match.

func RegexpStringSubmatchFunc

func RegexpStringSubmatchFunc(re *regexp.Regexp, replace func([]string) string) *RegexpTransformer

RegexpStringSubmatchFunc returns a transformer that replaces all matches of re with the result of calling replace with the submatch.

func RegexpSubmatchFunc

func RegexpSubmatchFunc(re *regexp.Regexp, replace func([][]byte) []byte) *RegexpTransformer

RegexpSubmatchFunc returns a transformer that replaces all matches of re with the result of calling replace with the submatch. The [][]byte parameter passed to replace should not be modified and is not guaranteed to be valid after the function returns.

func (*RegexpTransformer) Reset

func (t *RegexpTransformer) Reset()

Reset resets the state and allows a Transformer to be reused.

func (*RegexpTransformer) Transform

func (t *RegexpTransformer) Transform(dst, src []byte, atEOF bool) (nDst, nSrc int, err error)

Transform implements golang.org/x/text/transform#Transformer

type Transformer

type Transformer struct {
	transform.NopResetter
	// contains filtered or unexported fields
}

Transformer replaces text in a stream See: http://golang.org/x/text/transform

func Bytes

func Bytes(old, new []byte) Transformer

Bytes returns a transformer that replaces all instances of old with new. Unlike bytes.Replace, empty old values don't match anything.

func String

func String(old, new string) Transformer

String returns a transformer that replaces all instances of old with new. Unlike strings.Replace, empty old values don't match anything.

func (Transformer) Transform

func (t Transformer) Transform(dst, src []byte, atEOF bool) (nDst, nSrc int, err error)

Transform implements golang.org/x/text/transform#Transformer
