How do I save an entire string as a txt file in Go? - string

Question

I'm creating a simple word processing program in Go. From the command line, I have two prompts:
$Enter Title:
$Enter Body:
The program is supposed to save the document as a txt file and print it to the command line. The program works if the user user types in a one-word Title and a one-word Body. But if the user types in a several-word title, this will happen:
$Enter Title: Here is a title
$Enter Body: s
$ title
-bash: title: command not found
Here is the code I have so far:
package main
import (
"fmt"
"io/ioutil"
)
//Create struct for a document
type Document struct {
Title string
Body []byte
}
//Save document as txt file
func (p *Document) save() error {
filename := p.Title + ".txt"
return ioutil.WriteFile(filename, p.Body, 0600)
}
//Load document
func loadPage(title string) (*Document, error) {
filename := title + ".txt"
body, err := ioutil.ReadFile(filename)
if err != nil {
return nil, err
}
return &Document{Title: title, Body: body}, nil
}
//Input document title and body.
func main() {
fmt.Print("Enter Title: ")
var Title string
fmt.Scanln(&Title)
fmt.Print("Enter Body: ")
var Body []byte
fmt.Scanln(&Body)
//Save document and display on command line
p1 := &Document{Title: Title, Body: []byte(Body)}
p1.save()
p2, _ := loadPage(Title)
fmt.Println(string(p2.Body))
}

What about using bufio.ReadString instead of fmt.Scanln?
Not 100% how Scanln works, but I am pretty sure the issue comes from a misuse of that function.
Example with bufio:
package main
import (
"bufio"
"fmt"
"io/ioutil"
"log"
"os"
"strings"
)
// Document represent the document's data.
type Document struct {
Title string
Body []byte
}
// Save dumps document as txt file on disc.
func (p *Document) save() error {
filename := p.Title + ".txt"
return ioutil.WriteFile(filename, p.Body, 0600)
}
// loadPage loads a document from disc.
func loadPage(title string) (*Document, error) {
filename := title + ".txt"
body, err := ioutil.ReadFile(filename)
if err != nil {
return nil, err
}
return &Document{Title: title, Body: body}, nil
}
// Input document title and body.
func main() {
reader := bufio.NewReader(os.Stdin)
fmt.Print("Enter Title: ")
title, err := reader.ReadString('\n')
if err != nil {
log.Fatal(err)
}
title = strings.TrimSpace(title)
fmt.Print("Enter Body: ")
body, err := reader.ReadString('\n')
if err != nil {
log.Fatal(err)
}
body = strings.TrimSpace(body)
//Save document and display on command line
p1 := &Document{Title: title, Body: []byte(body)}
if err := p1.save(); err != nil {
log.Fatal(err)
}
p2, err := loadPage(title)
if err != nil {
log.Fatal(err)
}
fmt.Println(string(p2.Body))
}
