LANGUAGE

--[[
    HOW THE LANGUAGE WORKS :
        This is inspired by a stupid little 'secret language' my 2nd grade teacher taught me.

        Basically, take a word and iterate through the letters.  If the letter is a vowel,
            then leave it be.  If the letter is not a vowel, add "op" to the end of it.
            For example, "Hi" would result in "HOPi", and "face" would result in "fopacope"

local vowels = {
    a = true, e = true, i = true, o = true, u = true
}

local ignoreList = {
    ["."] = true, ["!"] = true, ["?"] = true, ["/"] = true
}

local translate = {

    toEnglish = function(words)
        local product = {}
        for letter = 1, words:len() do
            local let = words:sub(letter, letter)
            if (
                words:sub(letter + 1, letter + 2):lower() == "op" or
                vowels[let:lower()] and words:sub(letter + 1, letter + 1):lower() ~= "p" or
                ignoreList[let]
            ) then
                table.insert(product, let)
            end
        end
        return table.concat(product)
    end,

    toLanguage = function(words)
        local product = {}
        for letter = 1, words:len() do
            local let = words:sub(letter, letter)
            table.insert(
                product,
                let == " " and " " or
                ignoreList[let] and let or
                vowels[let:lower()] and let or
                let == let:lower() and let .. "op" or
                let .. "OP"
            )
        end
        return table.concat(product)
