For output, it"s easy to hack the string metatable so that "%s =
%5.2f" % {"hello",math. pi} works as expected
see http://lua-users.org/wiki/StringInterpolation
getmetatable("").__mod = function(a, b)
if not b then
return a
elseif type(b) == "table" then
return string.format(a, unpack(b))
else
return string.format(a, b)
end
end
