List filter question

[David Gifford]

Well, I tried to figure this out for a while but it is not working.

I need a list filter that turns up all tiddlers that neither have the tag 'sources' nor have any links of any kind within the text field. 

This is a list of tiddlers to clean up stragglers in my system.

Thanks in advance for your help!

David,

In such cases if you can list all the tiddlers you don't want you should be able negate it with a ! symbol.

If the links to which you refer are only wiki text I believe they are references. 

Could you list all tiddlers the and test to see if they haves no references?

I can give a fuller example if you want.

Regards

Tony

This approach with HelloThere at TiddlyWiki.com seems to work:

\define emptymessage() [[$(currentTiddler)$]]<br/>
<$list filter="[!tag[HelloThere]]">
<$list filter="[all[current]links[]limit[1]]" emptyMessage=<<emptymessage>>>
</$list>
</$list>

Notice that it doesn't catch links that are generated by macros. It also doesn't include http links as links.

But it might help you clean up stuff.

[Luis Gonzalez]

This macro does not catch links generated by macros or transclusions.

\define the_filter()

<!-- looks for [[link]] & [ext[link]] & [img[link]] links -->
<$set name="pattern" value="\[.*\[.+\]\]">

<!-- links shown as numbered list -->
<ol>
<$list filter="[all[]!is[system]] -[regexp:text<pattern>] -[tag[source]]">
<li><$link/></li>
</$list>
</ol>
</$set>

\end

Look at Chapter 9 of The-Book for a detailed explanation of filters and regular expressions.

Look at Announcing Tiddlywiki and regexp Examples and Tiddlywiki and regexp examples part ii: Working with fields  for regular expression.

Thanks Mark. Once I added !is[system] before the !tag[HelloThere], it worked as I needed it to.

Thanks Luis, for this option as well.

Oh, and sorry, everyone, I answered from email and forgot to remove my long and religious signature from my response to Mark. Some here have objected to that, and while I believe in free speech and am not embarrassed about my religious beliefs, I am sensitive to the fact that some here might see it as in-your-face proselytism, so I try to avoid that. It is a signature required by my employer. Please don't derail the thread by replying about this topic. I just wanted to preclude any objections anyone might have.
