How do I save an entire string as a txt file in Go? -
i'm creating simple word processing program in go. command line, have 2 prompts:
$enter title:
$enter body:
the program supposed save document txt file , print command line. program works if user user types in one-word title , one-word body. if user types in several-word title, happen:
$enter title: here title $enter body: s $ title -bash: title: command not found here code have far:
package main import ( "fmt" "io/ioutil" ) //create struct document type document struct { title string body []byte } //save document 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 , 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 , display on command line p1 := &document{title: title, body: []byte(body)} p1.save() p2, _ := loadpage(title) fmt.println(string(p2.body)) }
what using bufio.readstring instead of fmt.scanln? not 100% how scanln works, pretty sure issue comes misuse of function. example bufio:
package main import ( "bufio" "fmt" "io/ioutil" "log" "os" "strings" ) // document represent document's data. type document struct { title string body []byte } // save dumps document txt file on disc. func (p *document) save() error { filename := p.title + ".txt" return ioutil.writefile(filename, p.body, 0600) } // loadpage loads document 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 , 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 , 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)) }
