assert () is the best in your case (more verbose)

error () may also be helpful
especially if your error message requires complex evaluation:
-- This requires 'some_complex_call ()' even if there was no error:
assert (bar ~= "", "Error: "..some_complex_call ())

-- While this will call 'some_complex_call ()' only in case of error
if bar == "" then
  error ("Error: "..some_complex_call ())
end

do we have simple ASSERT like thing to do this automatic?

just like macro or other thing...

Sorry, but I mean, a new version of assert against the baselib one that _don't_ evaluate the second _expression_ if the first _expression_ is true.
