I'm learning go and I write simple standard i/o programs. Here's some code:

package main

import (
	"fmt"
	"math"
	"bufio"
	"os"
	"strconv"
	"strings"
)

func main() {
	reader := bufio.NewReader(os.Stdin)

*	var repeatAmount int
	fmt.Fscanf(reader, "%d\n", &repeatAmount)

	for i := 0; i < repeatAmount; i++ {
		var numberOfProgs int
		fmt.Fscanf(reader, "%d\n", &numberOfProgs)
. . .

I use lunarvim, which has nvim-dap and nvim-dap-ui preconfigured. I have installed and configured nvim-dap-go to add golang debugger configuration. If I place a breakpoint on a line marked with "*" and start debugging, the debugger skips over the fmt.Fscanf() and goes somewhere deep into golang's source code. It does not wait for user input and I assume the reason is it doesn't have any terminal to take user input from. How can I configure my settings so that the debugger would wait for user input?

You can run the program in the terminal and attach (option 4) to the running process selecting the correct pid.
