Hi Jeremy ...
I see - was expecting to that:
<$list filter="[all[shadows+tiddlers]tag[$:/tags/Image]]">
| {{!!title}} | <$transclude /> |
</$list>
Would be expanded into wiki text which in turn would be expanded into HTML
So I thought (wrongly) that I should write
<$list filter="[all[shadows+tiddlers]tag[$:/tags/Image]]">
<$wiki2html>
| {{!!title}} | <$transclude /> |
</$wiki2html>
</$list>
and wasted an hour or so Googling and reading the documentation searching
for the non-existent
$wiki2text (the magic thing that would turn wiki text into HTML)
The shortcut syntax is generally trying to be expressive but simple and

Bearing this in mind I ended up with
<table>
<tr class="evenRow"><th align="left">title</th><th>image</th></tr>
<$list filter="[all[shadows+tiddlers]tag[$:/tags/Image]]">
<tr><td>{{!!title}}</td><td><$transclude /></td></tr>
</$list>
</table>
I can't make my mind up if I like this or not - it mixes three abstraction
layers - I need to know
wikiText syntax, html syntax and need to know the specific html text the
wiki text expand into.
Actually having written this it now looks pretty simple -
Many of my problems arise from the documentation - there are many good
examples, so my problem
is one of "guess the semantics" - the code examples work, but I have to
guess the semantics (things like
the lifetimes of variable bindings, the scope of variables, evaluation
order etc.)
Thanks BTW for your patience in answering my questions.
