dealing with null (not nil)

[Dave Collins <Dave.Collins@...>]

I've just discovered that http://jsoneditor.net/ is mangling my data.

Our API delivers empty strings as mykey="". Now that I am setting up my app to run off either live API data or local .json file, I need to be able to edit the json file manually.

But after I make mods, the editor publishes my data - not as mykey="",  but as mykey=null - which my app chokes on.
(It also mangles numbers. It turns mykey="2" into mykey=2.) The nerve!!

Anyway, I can deal with the number problem, simply by wrapping it in tostring(). How do I deal with a null? Does lua have an isnull() function?

(I hate this idea that the editor is molesting my data. I can no longer count on my api data to be identical to my local file. Maybe I need to find a better editor. Maybe I need to complain to katamari that their editor molests my data.)

Or maybe I should make a mod to my json parser (dkjson) to have to autoconvert null to "".
