¶
Golang implementation of "getchar" function which allows you to intercept entered symbols right after key presses.
Installation
Use the go command:
go get github.com/NexoMichael/inputreader
Usage
package main
import (
"fmt"
"os"
"syscall"
input "github.com/NexoMichael/inputreader"
)
func main() {
reader, _ := input.NewInputReader(os.Stdin)
defer func() {
reader.Close()
}()
var b [1]byte
for {
n, err := reader.Read(b[:])
if err != nil || n == 0 {
return
}
fmt.Printf(" - code is %d\n\r", b[0])
switch syscall.Signal(b[0]) {
case syscall.SIGQUIT, syscall.SIGTERM, syscall.SIGINT:
return
}
}
}
Requirements
inputreader package requires Go >= 1.5.

Types ¶
type InputLine ¶
type InputLine struct {
// contains filtered or unexported fields
}
InputLine holds current eneterd line of symbols
func NewBuffer ¶
func NewBuffer() *InputLine
NewBuffer returns new InputLine buffer with default size equal to 4 KB.
type InputReader ¶
type InputReader struct {
// contains filtered or unexported fields
}
InputReader provides ReaderCloser interface for standart input or other input source pipe.
func NewInputReader ¶
func NewInputReader(in *os.File) (*InputReader, error)
NewInputReader returns a new InputReader for *os.File pipe.
func (*InputReader) Close ¶
func (r *InputReader) Close() (err error)
Close resets terminal settings to the initial state.
func (*InputReader) Read ¶
func (r *InputReader) Read(p []byte) (n int, err error)
Read reads data into p. It returns the number of bytes read into p. The bytes are taken from at most one Read on the underlying Reader, hence n may be less than len(p). At EOF, the count will be zero and err will be io.EOF.
