How to filter by field with a certain prefix in the value?

[Surya]

Hi all,

I have ToDo-tiddlers with due-fields. For example: One tiddler has in the field 18.03.15, another tiddler has in the due-field 18.03.23 and a third one has 18.04.11.

Is it possible (and how?) to filter these tiddlers in lists by due-field with the prefix 18.03? In order to see only the one with 18.03.15 and the one with 18.03.23?

Thanks for your help! Surya

The regular expression operator should do it:

<<list-links "[regexp:todo-field[^18.03]]">>

Hi Mark,

Thanx, but I have to specify my question.
Just inserting [regexp:todo-field[^18.03] after [tag[ToDo] didn't work.

I have a list with popups with this:

\define makeState()
<<qualify $(stateTiddler)$>>
\end

<div style="background:Lightgoldenrodyellow;">

<$list filter="[tag[ToDo]sort[due]]" variable="mytitle">

''Fällig am: ''<$edit-text tiddler=<<mytitle>> field="due"/>

<$set name="stateTiddler" filter="[<mytitle>addprefix[$:/temp/state/]]" emptyValue=error>
<$wikify name="qualstate" text=<<makeState>>>

* <$button class="tc-btn-invisible" popup=<<qualstate>>><$text text=<<mytitle>>/>
</$button>

<$reveal type="popup" position="below" state=<<qualstate>>>
<div class="mypopup">
<$tiddler tiddler=<<mytitle>>>

<$transclude tiddler=<<mytitle>>/>

</$tiddler>
</div>
</$reveal>
</$wikify>
</$set>
</$list>

<style>
.mypopup {
    min-width: 380px;
    border: 1px solid #bbb;
    background-color: #ffffff;
    padding: 1em;
    margin: 4px 0 0 0;
    text-shadow: none;
    line-height: 1.4;
}
</style>

How do I have to insert the regular expression operator in this list?

This should work:

[tag[ToDo]regexp:todo-field[^18.03]sort[due]]

Ahh, I found the mistake.
I described it wrong: The field is not called "due-field" but only "due".

So, the right is now (maybe, others have a similar question):

\define makeState()
<<qualify $(stateTiddler)$>>
\end

<div style="background:Lightgoldenrodyellow;">

<$list filter="[tag[ToDo]regexp:due[^18.03]sort[due]]" variable="mytitle">

Thank you :-)

Now I have for 99,9% that kind of ToDo-List, I wanted.
Don't waste too much view-space, small in MB-size, always only shows me what I need to see and relative simple to edit the due-dates of the recurring tasks :-)
