Hoe can I see all core images?

[joearms]

This makes a tag with a drop down of all core images

<<tag "$:/tags/Image">>

But this does not list them

<<list-links "[tag[$:/tags/Image]]">>

Any ideas why?

I think it's because the core images tagged $:/tags/Image are actually shadow tiddlers. The "tag" macro looks for shadow tiddlers by default. The list-links macro will only look for shadow tiddlers if you provide an appropriate filter that includes them:

<<list-links "[all[shadows+tiddlers]tag[$:/tags/Image]]">>

"Shadow tiddlers" are the payload tiddlers within plugins. They are hidden from most operations because they are not "real" tiddlers; this is done to reduce clutter.

Best wishes

Thank you Jeremy

Next question:  I want to make a neat table of the images

I did this:

<$list filter="[all[shadows+tiddlers]tag[$:/tags/Image]]">

| {{!!title}} | <$transclude /> | 

</$list>

In the hope that if I generated wiki text it would be expanded into a table

but this didn't work so I did this:

<$list filter="[all[shadows+tiddlers]tag[$:/tags/Image]]">

<tr><td>{{!!title}}</td><td><$transclude /></td></tr>

</$list>

Is this the right thing to do? - it's not very elegant

Cheers

Hi Joe

| {{!!title}} | <$transclude /> |

</$list>

That’s right. The shortcut table syntax is parsed as an entire static HTML table ie table, tbody, tr, and td.

The shortcut syntax is generally trying to be expressive but simple and easy to type, with the widget/element syntax waiting in the wings when you need more flexibility, as when constructing a table dynamically.

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 easy to type, with the widget/element syntax waiting in the wings when you need more flexibility, as when constructing a table dynamically.

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.

Cheers
