There does not appear to be a universal rule such as: "to prevent double
wikification, always use a <$text> widget when loading a $<wikify> widget
from a variable."
To show what I mean, consider this variation of Jeremy's test rig where I
set the variable to a heading string:
<$set name="testVar" value="! My Heading">
<$wikify name="testOutput1" text=<<testVar>> output="html">
<$text text=<<testOutput1>>/>
<<testOutput1>>
</$wikify>
<$wikify name="testOutput2" text="<$text text=<<testVar>>/>"
output="html">
<$text text=<<testOutput2>>/>
<<testOutput2>>
</$wikify>
</$set>
It results in this output:
<h1 class="">My Heading</h1>
My Heading
<p>! My Heading</p>
! My Heading
In this case the outcome is the opposite of the experience with tildes and
wikitext: using the <$text> widget results in the "wrong" result.
Is there a universal technique to ensure any variable value will be
rendered "correctly," or is it necessary to experiment with your input to
determine whether to use <$text> with it or not?
