func NewLuaState ¶

func NewLuaState() *lua.LState

NewLuaState creates a new lua state/VM

Set up a new lua VM. Limit the lua basic lib to essential functions in an attempt to reduce the scope of malicious scripts. This is actually really hard to do and the modules here are still condsidered dangerously unsafe but are neccessary if lua is to be used at all. Note that clever attackers can easily work around these limitations.

See http://lua-users.org/wiki/SandBoxes for info on the relative futility of trying to make lua VMs both safe and functional
