Look at below test code

<$vars x=>
<$text text={{{ [<x>length[]] }}}/>
</$vars>

Testing on https://tiddlywiki.com/prerelease/ results in

4

what is going wrong?

Hey Mohammad,

If you put a <<x>> in there before the $text, you can see that as you have it, x is "true", which is why length returns 4.

What a nice way to write obscure code.

Test for len 4 or len 5 for true false!

Diego,

Thank you for clarification.

But when you code, this is error prone!

This took a lot of time to debug a code! Undefined variable or wrongly assigned.

We really need a good TW documentation.

Mohammad,

I know how you feel, yet I do not have too many problems now, in part because I write code progressivly. I would have placed x=<<x>><br> in there as soon as it did not do as expected.
