go - Golang syntax error: unexpected EOF while writing to a file -

getting syntax error: unexpected eof on last line of code bracket. has file io because json code worked before added in

b, err := json.marshal(gfjson)     if err != nil {         panic(err)      filename := ".gfjson"      f, err := os.create(filename)     if err != nil {         panic(err)     }     // close file on exit , check returned error     defer func() {         if err := f.close(); err != nil {             panic(err)         }     }()       if _, err := f.write(b); err != nil {         panic(err)     }      fmt.fprintf(os.stdout, "gfjson file created.\n") } 

you missing closing bracket on line 4 after panic.

if err != nil {     panic(err) } 

your code compiles fine me, because have random closing brace @ end balancing out. assume indentations close brace @ end end of function , panic should part of if statement.
