Small example

package main

import (
  "bufio"
  "fmt"
  "github.com/frida/frida-go/frida"
  "os"
)

var script = `
Interceptor.attach(Module.getExportByName(null, 'open'), {
	onEnter(args) {
		const what = args[0].readUtf8String();
		console.log("[*] open(" + what + ")");
	}
});
Interceptor.attach(Module.getExportByName(null, 'close'), {
	onEnter(args) {
		console.log("close called");
	}
});
`

func main() {
  mgr := frida.NewDeviceManager()

  devices, err := mgr.EnumerateDevices()
  if err != nil {
    panic(err)
  }

  for _, d := range devices {
    fmt.Println("[*] Found device with id:", d.ID())
  }

  localDev, err := mgr.LocalDevice()
  if err != nil {
    fmt.Println("Could not get local device: ", err)
    // Let's exit here because there is no point to do anything with nonexistent device
    os.Exit(1)
  }

  fmt.Println("[*] Chosen device: ", localDev.Name())

  fmt.Println("[*] Attaching to Telegram")
  session, err := localDev.Attach("Telegram", nil)
  if err != nil {
	  fmt.Println("Error occurred attaching:", err)
	  os.Exit(1)
  }

  script, err := session.CreateScript(script)
  if err != nil {
    fmt.Println("Error occurred creating script:", err)
	os.Exit(1)
  }

  script.On("message", func(msg string) {
    fmt.Println("[*] Received", msg)
  })

  if err := script.Load(); err != nil {
    fmt.Println("Error loading script:", err)
    os.Exit(1)
  }

  r := bufio.NewReader(os.Stdin)
  r.ReadLine()
}

Build and run it, output will look something like this:

$ go build example.go && ./example
[*] Found device with id: local
[*] Found device with id: socket
[*] Chosen device:  Local System
[*] Attaching to Telegram
[*] Received {"type":"log","level":"info","payload":"[*] open(/Users/daemon1/Library/Application Support/Telegram Desktop/tdata/user_data/cache/0/25/0FDE3ED70BCA)"}
