Hello,
I am trying to understand how plugin works & have adjusted the sample in the
tutorial.
How do I get data from the handle into render?
I want to put the likes of <KEYCONV|red> into a wiki page and have it return
"Hello
Worldred"
Below is what i tried and failed. Please show me how to do this.
Thanks
Tony
