Here is the actual use case where I concatenate a number of tiddlers
describing plugins. For each tiddler I am using the concatenated content of
a tiddler field as a heading, prefixing it with a '! ' heading token.
<$list filter="[tag[InstalledPlugin]sort[title]]">
<$setvars pluginNames="[input[][][, ]]" _input={{!!plugin.names}}>
<$wikify name="pluginsHeading" text="""! <$text
text=<<pluginNames>>/>""" output="html">
<<pluginsHeading>>
</$wikify>
</$setvars>
<$transclude mode="block" tiddler=<<currentTiddler>>/>
</$list>
Here is where I needed the to use <$text> to ensure tildes in the field
content are honoured.
Can the above snippet be simplified?
