Functions ¶
func BufReader ¶
BufReader return a new bufio.Reader from exist io.Reader if current reader is already bufferd, return itself
func BufWriter ¶
BufWriter return a new bufio.Writer from exist io.Writer if current Writer is already bufferd, return itself
func Filter ¶
Filter readline from reader, after filter, if sync set at the end, and writer is non-null, write content to writer, otherwise, every read operation will followed by a write operation
return an error to stop filter, io.EOF means normal stop
func FilterRead ¶
FilterRead filter line from reader
func NopLineFilte ¶
NopLineFilter do nothing, just return the line
func WriteLString ¶
WriteL write a string list to writer, return total bytes writed
func WriteStringln ¶
WriteStringln write string to writer and append a newline character

func (*ErrorWriter) WriteString ¶
func (w *ErrorWriter) WriteString(s string) (int, error)
type WriterChain ¶
type WriterChain interface {
io.Writer
// Wrap add a new writer to top of chain
Wrap(io.Writer)
// Unwrap remove writer from top of chain, if there is only the base writer
// nil was returned
Unwrap() io.Writer
// IsWrapped check whether a chain has wrapped writer
IsWrapped() bool
// Writer return the top writer
Writer() io.Writer
// BaseWriter return the base writer
BaseWriter() io.Writer
}
func NewWriterChain ¶
func NewWriterChain(wr io.Writer) WriterChain
NewWriterChain create a new writer chain based on given writer parameter must not be nil, otherwise, nil was returned
