Return nothing, blank, empty string from JS macro (how?)

Title says it all. For all of "", [], [""] I get true.

#2

Returning "" seems to be working for me:

(function(){

exports.name = "empty";

exports.params = [];

exports.run = function() {
	return "";
};

})();

See it in action at this share site url.

Hmm. Odd. Now I can’t make it break. If it comes back, so will I :slight_smile:

Thanks for checking!

There is a related case where in filters a nul output still returns true, the way I recall dealing with this is ensuring that does not flow through by using !is[blank] on the occasion where the empty case seems to come through. I could be more in the way to reference this output, not the way your function works (not nessasarily)

  • Not precise I know, but it has worked for me.

I had similar thoughts. I was storing a filter and then the results of a filter. Might have been that. Problem is, the code has moved on since it was happening…

Like I said, I might be back…
