I use this simple function to get system variables as TMP or ProgramFiles. It would be useful to implement it directly in the program?
function Env(var)
local eev = kernel32.ExpandEnvironmentStringsA
eev:types{ ret = "long", abi = 'stdcall', "string", "pointer", "long" }
local buffer = aliencore.buffer(512)
eev("%" .. var .. "%", buffer, 512)
return tostring(buffer)
end
Actually I think it will be good to provide folks with a .lua file which includes a bunch of functions that people have come up with. The reason I built Alien and Lua into S+ was so people could add functionality without needing a new version to be released.
There's really no reason to build this into S+ as it works fine here. If eev was defined in Global Lua (instead of being instantiated for each call to Env), it's not really much different than if it were built-in.
