LibKnot : Go interface for managing the Knot DNS daemon

LibKnot is a GoLang interface to manage the KnotDNS daemon using the C library (libknot) based on the (official Python interface].

Since the software loads the C library dynamically, you must install it on your development and production machine. When publishing compiled software, pay attention to the version of libknot used.

Usage

You can uses this library in two ways :

• Use wrapper functions, easier to use.
• Directly control the server with the functions Alloc(), Connect(), Close(), Free(), Send(), Receive() and manage data types.

Examples

• Basic example using wrapper functions :

package main

import (
	"fmt"
	
	"github.com/outout14/libknot"
)

func main() {
	ctl := libknot.KnotCtl{} //Define the connection

	err := ctl.Init("/var/run/knot/knot.sock") // Allocate de control context + Connect(socket)
	ctl.ErrCheck(err)                          //Panic if err != 0 and print the error as a human readble string

	/* Send */
	msg := libknot.KnotCtlData{
		Command: "conf-read",
		Section: "zone",
		Item:    "domain",
	}
	_ = ctl.SendBlock(msg) //Send DATA msg + BLOCK (BLOCK = End of message)
	/* End Send */

	/* Receive */
	data, _ := ctl.ReceiveBlock() //Retrieves all DATA and EXTRA type messages

	for _, s := range data {
		fmt.Println(s.Data) //Print received data
	}
	/* End Receive*/

	ctl.Terminate() //Send(END) + Close() + Free() control ctx
}
