Simple table enumeration script

[Einlander]

I started playing around with the networking in Leadwerks and found that I needed enums. So I wrote a function that will allow you to enumerate a table.

 

function enumerate(array,indexstart) -- indexstart is optional
	if array == nil then return nil end
	local array2 = {}
	local count = tonumber(indexstart) ~= nil and tonumber(indexstart) or 0
	for key,value in pairs(array) do
		array2[value] = count
		count = count + 1		
	end
	return array2
end

This will take an array of strings and output a named table array.

 

enum_netchat =  enumerate({
  "client",
  "team",
  "all",
  "servertoclient",
  "servertoteam",
  "servertoall"
},1)

 

This is the simplest way to make an enum

	enum_netchat.all

So this results in the below?

enum_netchat = {    
    client = 1,
    team = 2,
    all = 3,
    servertoclient = 4,
    servertoteam = 5,
    servertoall = 6
}
