func main() {
	myClient := Client{Name: "Noku", BotName: "RegBot"}
	resultStruct := stemp.CompileStruct("Hello [{Name:j=c,w=1,f=*}], I'm {BotName}. Nice to meet you {asdasds}. I'm accessing the values from a struct!", myClient)
   	fmt.Println(resultStruct)
    

	data := []string{
		"Mays,123 st. 456 Lane",
		"Harold,523 st. Sunset Overdrive",
	}
    	result := stemp.CompileJSON("   |{col1:j=c,w=10}|{col2:j=c,w=40}|\n---------------------------------------------------\n", `{"col1": "Name", "col2": "Address"}`)
	for idx, d := range data {
		s := strings.Split(d, ",")
		result += stemp.Compile("{idx:w=3}|{name:j=c,w=10}|{add:j=c,w=40}|\n", map[string]interface{}{"idx": idx, "name": s[0], "add": s[1]})
	}
	fmt.Println(result)
	
	fmt.Println(stemp.Inline("{0} is {1:w=4,j=r,f=0} degrees celsius.", "Today", 23))
