What do you think about this as a start:

env.getenv(name)
env.setenv(name, value)
env.environ()


What about:

  env[name]
  env[name] = value
This is easy enough to do in pure Lua; it doesn't need to be provided by a binary module, IMHO: 

require "ex"
local environ = {}
function environ:__index(k) return os.getenv(k) end
function environ:__newindex(k,v) os.setenv(k,v) end
environ = setmetatable({}, environ)


I'd like to add "glob" but I don't know how it can be implemented in windows.


Worst case - code it by hand
Sure. Again, this is something that pure Lua can do when provided a primitive directory iterator: 

require "ex"
for e in os.dir"." do
   if e.name:match"[.]html$" then
      print(e.name)
   end
end
Note that if you want /bin/sh globbing as specified by POSIX, then you'd be better off actually wrapping glob(3) itself. However, be sure that in this case your Lua program is targetting POSIX and since the POSIX glob() semantics are something that do not exist on other systems, your program is inherently non-portable to non-POSIX, non-UNIX-y systems.
