如何在lua中递归地走Windows注册表？

Question

I'm coming from linux land so bear with me please.

I want to walk through windows registry recursively. All I've managed to do so far get the values of individual keys

> require 'luacom'
> sh = luacom.CreateObject "WScript.Shell"
> = sh:RegRead "HKCU\\Console\\ColorTable01"
8388608

yet see no way to iterate registry nodes...

If you need to do anything Windows-specific with Lua, your first port of call should be the winapi library; in this case, you can enumerate over Registry keys with open_reg_key() and Regkey:get_keys() like so:

require "winapi"
local key, err = winapi.open_reg_key [[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows]]
local t = key:get_keys()
for k,v in ipairs(t) do print(k,v) end
