If you hack $:/core/ui/ViewTemplate/body to show
<$reveal tag="div" class="tc-tiddler-body" type="nomatch" stateTitle=<
<folded-state>> text="hide" retain="yes" animate="yes">
<$list filter="[all[current]!has[plugin-type]!field:hide-body[yes]]">
<$tiddler tiddler=<<currentTiddler>>>
<$transclude tiddler="transme">
<$transclude tiddler="$:/language/MissingTiddler/Hint"/>
</$transclude>
</$tiddler>
</$list>
</$reveal>
and create tiddler transme like:
\define pairs()
<$vars $(kp)$>
<$transclude field=text mode=block/>
</$vars>
\end
\define keypairs()
<$vars triple="'">
<$list filter="[all[current]fields[]] -[[text]] -[[title]] -created
-modified -tags" variable=fieldname>
<<fieldname>>=<<triple>><$text text={{{ [all[current]get<fieldname>] }}} /
><<triple>>
</$list>
</$vars>
\end
<$wikify name=kp text="""<<keypairs>>""" >
<$macrocall $name=pairs />
</$wikify>
Then this will do what you want, at least under some circumstances.
It may not work with all possible field content values.
The big problem was TW's overwhelming urge to "eat" all quote marks,
leaving nothing to pass to the various macros.
Improvements should include:
* Only applying template for certain tagged tiddlers
* Create variable names like tony_<name> so that there is little
possibility of conflict with existing variables in macros, environment
Be sure to put some sort of reminder in the file that you have hacked a
core template so you don't get blind-sided on the next upgrade.
