enclose string in [[...]] only if contains spaces

[Rustem]

I'm looking for a macro or something that would enclose a string containing spaces in double-square brackets, but leave a single-word string as is.
Any hints?

What is the problem about enclosing a string without spaces in double square brackets? it will work the same and it is easier.

[Rustem]

I agree. I think this problem is commonly referred to as OCD. Can't live with extraneous brackets. :D

Hi Rustem

The core already contains a function stringifyList() that does what you want:

You could wrap it into a JS macro,

Best wishes

Actually, I realized set widget will do it for me, as described in http://tiddlywiki.com/static/SetWidget (see “Filtered List Variable Assignment”).

However, can anybody explain why this does not work as expected (assuming currentTiddler title contains spaces)

<$set name=myVariable filter="[[$(currentTiddler)$]] [[another one]]">
<$text text=<<myVariable>>/>
</$set>

but this does:

<$set name=myVariable filter="[all[current]] [[another one]]">
<$text text=<<myVariable>>/>
</$set>

[Rustem]

I should have just used [<currentTiddler>] instead of [[$(currentTiddler)$]]. Not sure what the deal with the latter is. Used in a list filter, it causes too much recursion.
