How to print/display args[0] in a different passage from when it was used earlier

Question

Using this code (as a widget):

<<widget Add_ItemToInv>><<nobr>>
<<set $ItemAdded = "args[0]">>
<<if $Inventory.includes($args[0])>>
<<set $TextMessage = "You already have the item $ItemAdded in your inventory.">>
<<else>>
<<set $TextMessage = "You have added the $ItemAdded to your inventory.">>
<<endif>>
<<set $Inventory.pushUnique($args[0])>>
$TextMessage
<</nobr>><</widget>>

How can i then display/print out $TextMessage (i.e args[0]) in a different passage at a later point, without getting something like this:

You have added the $args[0] to your inventory.

I get you're supposed to use <<print>>, but i'm not entirely sure how to do it properly in practice. The widget itself on it's own works fine and displays/prints properly, but when i use $TextMessage somewhere else or outside the widget, i get the following above.

Thanks

The problem is that putting "args[0]" inside quotes means that it's a string, not a variable.  What you want to do is this:

<<widget "Add_ItemToInv">><<nobr>>
	<<if $Inventory.includes($args[0])>>
		You already have the item $args[0] in your inventory.<br>
	<<else>>
		You've added the $args[0] to your inventory.<br>
		<<set $Inventory.push($args[0])>>
	<</if>>
<</nobr>><</widget>>

Note that you're supposed to use "<</if>>", and NOT "<<endif>>".  The "<<endif>>" marker is depreciated and may not work in future releases.

Also, instead of using "<<nobr>>" macros in your widgets, you might want to just have a "nobr" tag on your widget passage(s) instead.

Hope that helps!  :-)

It isn't possible to print it as a string? Doing it without $TextMessage as a string means i would have to use the widget more than once to show the same text.

Good to know about the <<endif>> though, thanks :)

As demostrated by the <<widget>> macro's examples the name argument of that macro is a String so the value should be quoted. Your widget declaration should look as follows.

<<widget "the-widget-name">>
	/* your code */
<</widget>>

Your current declaration is relying on SugarCube guessing the data type of the argument you are suppling the <<widget>> macro.

I don't think i understand entirely, if i quote the widget macro i still just get back something like this (when not setting args[0] as a string)

You have added the $ItemAdded to your inventory.

If you look at the example I gave you will notice that the widge name String argument..
"the-widget-name"
...I passed to the <<widget>> macro (used to define the custom widget) is wrapped in quotes.

Or if you perfer an example based on your own original one...

<<widget "Add_ItemToInv">><<nobr>>
	/* the code of your widget.. */
<</nobr>><</widget>>

(note that the "Add_ItemToInv" value being passed to the <<widget>> macro is quoted)

Yeah i understand and that's exactly what i did :) -  it just doesn't seem to change anything to put the widget name in quotes.

"It isn't possible to print it as a string?"

Of course it's possible, it just didn't seem necessary.  If you need that then do this:

<<widget "Add_ItemToInv">><<nobr>>
	<<set $ItemAdded = $args[0]>>
	<<if $Inventory.includes($args[0])>>
		<<set $TextMessage = "You already have the item " + $args[0] + " in your inventory.">>
	<<else>>
		<<set $TextMessage = "You've added the " + $args[0] + " to your inventory.">>
		<<set $Inventory.push($args[0])>>
	<</if>>
	$TextMessage<br>
<</nobr>><</widget>>

Now $ItemAdded will get set to the first value passed to the macro and $TextMessage will get set to the output of that macro.  If you don't use $ItemAdded then you can get rid of that line.
