Replace space in currentTiddler variable with underscore

[Ankit Mittal]

Hi,

I have been trying to get a variable set such that it has the title of current toddler without spaces. I tried following but it did not work...

\define testCreate()
<$set name=test filter=""" <<currentTiddler>> +[join[_]] """>
<<test>>
</$set>

\end

<<testCreate>>

If title of current tiddler is "Hello There Abbey", I was hoping above macro would result in Hello_There_Abbey but it did not.

What am I doing wrong and what can I do to achieve what I am after?

Try this:

<$set name="test" filter="[<currentTiddler>split[ ]join[_]]">
<<test>>
</$set>

You can also achieve the same results with the <$vars> widget, using an "inline filter", like this:

<$vars test={{{ [<currentTiddler>split[ ]join[_]] }}}>
<<test>>
</$vars>

and, if you just want to *display* the value, you don't even need the $vars.  Just write:

<$text text={{{ [<currentTiddler>split[ ]join[_]] }}}/>

enjoy,

And if you want a link to a tiddler by the new name

{{{ [<currentTiddler>split[ ]join[_]] }}}

Just to fill out Eric's comprehensive answer.
