package readline

import "github.com/chzyer/readline"

Readline is a pure go implementation for GNU-Readline kind library.

example: 

rl, err := readline.New("> ")
if err != nil {
	panic(err)
}
defer rl.Close()

for {
	line, err := rl.Readline()
	if err != nil { // io.EOF
		break
	}
	println(line)
}

Package terminal provides support functions for dealing with terminals, as commonly found on UNIX systems.

Putting a terminal into raw mode is the most common requirement: 

oldState, err := terminal.MakeRaw(0)
if err != nil {
        panic(err)
}
defer terminal.Restore(0, oldState)
