sLiner

Allows for a pre-filled input field of a single line.

If you would pass a empty string to pre-fill the input line, just do not bother with this package, use the standar library.

This is a copy of liner, all credits to the original creator, I only strip his project of the thing I do not need.

I want something even simpler than that, but I do not want it to be a fork, so I copy it.

Change my mind, too clompex, I just want a pre-filled input prompt that works on Linux.

Line Editing

The following line editing commands are supported on Linux and are not really tested.

Keystroke	Action
Ctrl-A, Home	Move cursor to beginning of line
Ctrl-E, End	Move cursor to end of line
Ctrl-B, Left	Move cursor one character left
Ctrl-F, Right	Move cursor one character right
Ctrl-Left, Alt-B	Move cursor to previous word
Ctrl-Right, Alt-F	Move cursor to next word
Ctrl-D, Del	(if line is not empty) Delete character under cursor
Ctrl-D	(if line is empty) End of File - usually quits application
Ctrl-C	Reset input (create new empty prompt)
Ctrl-L	Clear screen (line is unmodified)
Ctrl-T	Transpose previous character with current character
Ctrl-H, BackSpace	Delete character before cursor
Ctrl-W, Alt-BackSpace	Delete word leading up to cursor
Alt-D	Delete word following cursor
Ctrl-K	Delete from cursor to end of line
Ctrl-U	Delete from start of line to cursor
Ctrl-Y	Paste from Yank buffer (Alt-Y to paste next yank instead)

Getting started

package main

import (
	"github.com/malklera/sliner/pkg/liner"
	"log"
)

func main() {
	line := liner.NewLiner()
	defer line.Close()

	log.Println("What is the best language?")

	input, err := line.PrefilledInput("Go", -1)

	if err != nil {
		log.Fatalf("Error with the input: %v", err)
	}

	log.Printf("The best language is '%s'", input)
}
