Convert string to bool in Golang

Converting string to bool can be done using the strconv.ParseBool method. It tries to return a boolean value from a string. It accepts the strings in the following format

// True string values
1, t, T, TRUE, true, True

// False string values
0, f, F, FALSE, false, False

Anything else apart from these value will throw an error when using the strconv.ParseBool method.

// stringVal can be set to any one of the above valid values.
value, err := strconv.ParseBool(stringVal)

Example for converting string to bool in Golang

package main

import (
	"fmt"
	"strconv"
)

func main() {

	// Success conversion with no error
	boolString := "True"
	boolVal, err := strconv.ParseBool(boolString)

	if err != nil {
		fmt.Println("Error in conversion", err)
	} else {
		fmt.Println("Converted Boolean value - ", boolVal)
	}

	// Error conversion
	boolErrString := "Abcd"
	boolErrVal, err := strconv.ParseBool(boolErrString)

	if err != nil {
		fmt.Println("Error in conversion", err)
	} else {
		fmt.Println("Converted Boolean value - ", boolErrVal)
	}

}

Steps to convert

1. Create a variable of string which will contain one of the valid formats of representing bool as string
2. Pass the value to strconv.ParseBool method to get a value or error
3. Check the error variable is there is any error and if so print the error
4. If there is no error, you can use the value
