Sending linebreak/returns in API

I've ran into a roadblock I cannot seem to get around. Sending any text to API where a carriage return is used only sends the first line.

For example on the character sheet I have this block of html (trimmed down to important parts):

<fieldset class="repeating_cast">
        <button type='roll' value='!cast --@{CASTdesc}' name='roll_CastCheck' /></button>
        <textarea class="sheet-casttext" name="attr_CASTdesc"></textarea>
</fieldset>

The important parts is the button that sends an API command of
"!cast --@{CASTdesc}"
Where @{CASTdesc} is the textarea. 

And the text area, which could have for example inside it:

One
Two
Three

Problem is the API message sent, only sees "One".

If I make the textarea on the sheet say:

One Two Three

It reads it all.

Anyone know a fix/workaround for this?

You can surround with {{ }} to use multiple lines.  See TokenMod:

            args = msg.content
                .replace(/<br\/>\n/g, ' ')
                .replace(/(\{\{(.*?)\}\})/g," $2 ")
                .split(/\s+--/);

In my case, I'm stripping out the newlines, but you could use something like:

          msg.content.replace(/\s*(\{\{|\}\})\s*/g,' ');

Surround which part, What I have the sheet sending?
I'm assuming that part, as I THINK its already lost before the chat:message sees it.

So as such:
!cast {{--@{CASTdesc}}}

Yes, exactly.

I'll try that, I've been throwing html and js at the wall for 2 hours trying to get something to stick.
What would we do without you!

That did exactly what I needed. Go get one virtual beer, on me!

I'm virtually drunk already! =D
