When executing the main function which requires command line arguments, user can
set `go-run-args` to pass command line arguments to compiled binary.
The example below demonstrates how to pass command line arguments by setting
`go-run-args` as file local variable:
package main
import (
"fmt"
"os"
"strconv"
)
func main() {
//Atoi converts a string to an int
fmt.Println("Arguments:", os.Args)
a, _ := strconv.Atoi(os.Args[1])
b, _ := strconv.Atoi(os.Args[2])
result := sum(a, b)
fmt.Printf("The sum of %d and %d is %d\n", a, b, result)
}
func sum(a, b int) int {
return a + b
}
// Local Variables:
// go-run-args: "10 5"
// End:
