I'm following the Go tour, and still trying to learn the basics of the language. For the imported package time, is there a way to access its exports with a variable? E.g. time[day] instead of time.Saturday
Here's a more complete example
package main
import (
"fmt"
"time"
)
func main() {
day := "Thursday"
fmt.Printf("When's %v?", day)
today := time.Now().Weekday()
switch time[day] { // This is how I would do it in javascript
case today + 0:
fmt.Println("Today.")
default:
fmt.Println("Too far away.")
}
}
Also, what is the correct terminology for what I want to do? I'm having very little luck using Google
No, there's no way to reference exported variables from a package, which are stored on the stack, without explicitly referencing them using a data structure that you define that's built at runtime.
For example, you could do:
var days = map[string]time.Weekday{
"Monday": time.Monday,
"Tuesday": time.Tuesday,
"Wednesday": time.Wednesday,
"Thursday": time.Thursday,
"Friday": time.Friday,
"Saturday": time.Saturday,
"Sunday": time.Sunday,
}
fmt.Println(days["Thursday"])
