This is pretty much a request.

Anybody knows where I can find a precisely defined algorithm for a binary-tree based heap data structure?

All I can find is either array-based or fuzzy as fuck.

Thanks in advance.

Fuck, sorry for the noobness.

function Proxy(object, handler)

  local p = {}



  local get

  if handler.get ~= nil then

    get = function(target,key)

      return handler.get(object, key)

    end

  else

    get = object

  end



  local set

  if handler.set ~= nil then

    set = function(target,key)

      return handler.set(object, key)

    end

  else

    set = object

  end



  setmetatable(p, {

    __index = get,

    __newindex = set

  })



  return p

end



function contains(object, key)

  return rawget(object,key) ~= nil

end

Examples
Very simple example

An object with 37 as its default value when the property name is not in the object



handler = {

  get = function(target, name)

    local key = rawget(target, name)

    if key ~= nil then return key

    else return 37

    end

  end

}



p = Proxy({}, handler)

p.a = 1

p.b = "fuck you undefined isn't necessary!"



print(p.a, p.b) -- 1, "fuck you undefined isn't necessary!"

print(contains(p, 'c'), p.c) -- false, 37

No-op forwarding proxy

In this example, we are using a native Lua object to which our proxy will forward all operations that are applied to it.



target = {}

p = Proxy(target, {})



p.a = 37 -- operation forwarded to the proxy



print(target.a) -- 37. The operation has been properly forwarded

and lua can actually do this more succinctly. I had to modify the usual style a bit to get it to fit with the javascript examples. Usually you don't need to introduce a proxy object and instead just make objects directly inherit from other objects.

xp is being deprecated next year, and updates for ie9+ happen in background and their feature support is competitive with chrome/ff since microsoft is forced to take web/open source seriously by pouring money into node and so on.

ie8 down to 13% and ie7/6 is >2 combined.
