Here goes my Tavern.kt class

Answer:

import java.io.File

const val TAVERN_NAME = “Taernyl’s Folly”
var patronList = mutableListOf(“Eli”, “Mordoc”, “Sophie”)
val lastName = listOf(“Ironfoot”, “Fensworth”, “Baggins”)
var menuList = File(“data/tavern-menu-items.txt”).readText().split("\n")
var uniquePatrons = mutableSetOf()
val patronGold = mutableMapOf<String, Double>()
fun main() {
initialize()
/patronList.forEachIndexed() { index,patron ->
println(“Good evening, patron - you're #{index+1} in the line”)
placeOrder(patron,menuList.shuffled().first())
}
menuList.forEachIndexed{index,data->
println("$index $data")
}/

(0..9).forEach {
    val first = patronList.shuffled().first()
    val last = lastName.shuffled().first()
    val name = "$first $last"
    uniquePatrons.plusAssign(name)
}
println(uniquePatrons)
uniquePatrons.forEach {
    patronGold[it] = 6.0
}
var orderCount = 0
while (orderCount <= 9) {
    if(uniquePatrons.count()>0) {
        placeOrder(uniquePatrons.shuffled().first(), menuList.shuffled().first())
        orderCount++
    }else{
        println("Nobody in the list")
        break
    }
}
displayPatronBalance()

}

fun initialize() {
if (patronList.contains(“Eli”)) {
println(“The tavern master says: Eli’s in the back playing cards”)
} else {
println(“The tavern master says Eli isn’t here”)
}
if (patronList.containsAll(listOf(“Mordoc”, “Sophie”))) {
println(“The tavern master says: Yea they’re seated by the stew kettle.”)
} else {
println(“The tavern master says: Nay, they departed hours ago.”)
}
}

fun placeOrder(patronName: String, menuData: String) {
val indexOfApostrophe = TAVERN_NAME.indexOf(’’’)
val tavernMaster = TAVERN_NAME.substring(0 until indexOfApostrophe)
val (type, name, price) = menuData.split(’,’)
val message = “$patronName buys a $name ($type) for $price”
println("$patronName speaks with $tavernMaster about their order")
println(message)
if(performPurchase(price = price.toDouble(), patronName = patronName)) {
val phrase = if (name == “Dragon’s Breath”) {
“patronName claims: {toDragonSpeak(“Ah Delicious $name”)}”
} else {
“$patronName says: Thanks for the $name”
}
println(phrase)
}else{
println(“Patron $name booted from NyetHack”)
patronGold.remove(patronName)
uniquePatrons.remove(patronName)
}
}

private fun toDragonSpeak(phrase: String) = phrase.replace(Regex("[aAeEiIoOuU]")) {
when (it.value) {
“a” -> “4”
“A” -> “4”
“e” -> “3”
“E” -> “3”
“i” -> “1”
“I” -> “1”
“o” -> “0”
“O” -> “0”
“u” -> “||"
“U” -> "||”
else -> it.value
}
}

fun performPurchase(price: Double, patronName: String): Boolean {
val balance = patronGold.getValue(patronName) - price
return if (balance > 0) {
patronGold[patronName] = balance
true
} else {
//patronGold.remove(patronName)
false
}
}

fun displayPatronBalance() {
patronGold.forEach { (patron, balance) ->
println("patron, balance: {"%.2f".format(balance)}")
}
}

This is getting interesting… Here is my answer to this NyetHack Challenge.
Here is only the code changed

private fun placeOrder(patronName: String, menuData: String) {
    val indexOfApostrophe = TAVERN_NAME.indexOf('\'')
    val tavernMaster = TAVERN_NAME.substring(0 until indexOfApostrophe)
    println("$patronName speaks with $tavernMaster about their order.")

    val data = menuData.split(',')
    val type = data[0]
    val name = data[1]
    val price = data[2]

    if (patronGold.getValue(patronName) > price.toDouble()) {

        val message = "$patronName buys a $name ($type) for $price."
        println(message)

        performPurchase(price.toDouble(), patronName)

        val phrase = if (name == "Dragon's Breath") {
            "$patronName exclaims: ${toDragonSpeak("Ah, delicious $name!")}"
        } else {
            "$patronName says: Thanks for the $name."
        }

        println(phrase)
    } else {
        println("You don't have enough money, $patronName. Get out of here!")
        patronGold.remove(patronName)
        uniquePatrons.remove(patronName)
    }
}

private fun placeOrder(patronName: String, menuDate: String){
val indexOfApostrophe = TAVERN_NAME.indexOf(’’’)
val tavernMaster = TAVERN_NAME.substring(0 until indexOfApostrophe)
println("$patronName speaks with $tavernMaster about their order.")

val(type,name,price) = menuDate.split(',')
val message = "$patronName tries to buy a $name ($type) for $price"

println(message)

//my solution at the moment
if (patronGold.getValue(patronName)>= price.toDouble()) {
performPurchase(price.toDouble(), patronName)

    val phrase = if (name == "Dragon's Breath") {
        "$patronName exclaims: ${toDragonSpeak("Ah, delicious $name!")}"
    } else {
        "$patronName says: thanks for the $name"

    }
    println(phrase)
    println("$patronName has ${patronGold[patronName]}")
}else{
    println("$patronName dose not have enough money and bouncer kicked him out ")
    uniquePatrons.remove(patronName)
    patronGold - (patronName)

}
