RE: How-to LUA script file access restrictions?

[Benoit Germain <bgermain@...>]

In lua, you could do something like this before any of the client scripts
try to open a file:

local io_open = io.open

-- this replacement ensures that the unrestricted version becomes
unavailable
io.open=function(<args>)
	--restrict paths here
	if <path is authorized>
	then
		return io_open(<args>)
	else
		return nil
	end
end



Cheers,

Benoit.

Objet : How-to LUA script file access restrictions?


Is there any possibility to restrict file access from scripts to specified
paths only without modifying the lua source code ?
