I’m trying to translate following Go code into Elixir. I’ve also included my own attempt.
package main
import "fmt"
const spanish = "Spanish"
const french = "French"
const englishHelloPrefix = "Hello, "
const spanishHelloPrefix = "Hola, "
const frenchHelloPrefix = "Bonjour, "
// Hello returns a personalised greeting in a given language.
func Hello(name string, language string) string {
if name == "" {
name = "World"
}
return greetingPrefix(language) + name
}
func greetingPrefix(language string) (prefix string) {
switch language {
case french:
prefix = frenchHelloPrefix
case spanish:
prefix = spanishHelloPrefix
default:
prefix = englishHelloPrefix
}
return
}
func main() {
fmt.Println(Hello("world", ""))
}
Below I have my attempt at converting it to Elixir. I just want to make sure it’s the “Elixir way” of doing things. What would you all have done differently?
defmodule Hello do
@english_hello_prefix "Hello, "
@spanish_hello_prefix "Hola, "
@french_hello_prefix "Bonjour, "
# Returns a personalised greeting in a given language.
def hello(name, language) do
name = if name == "" do
"World"
else
name
end
greeting_prefix(language) <> name
end
def greeting_prefix(language) do
case language do
"french" -> @french_hello_prefix
"spanish" -> @spanish_hello_prefix
_ -> @english_hello_prefix
end
end
end
IO.puts Hello.hello("world", "")
