Filter lists by tags and exclude tiddler with specific tags.

[Mammut]

Hi @ all,

I searched a lot and red many discussions, but couldnt find a suitable
answer.
Maybe someone can help me or delegate me to an already existing
helpful thread.

I try to create a list (in a tiddler) which is filtered by tags.
Finally the list should contain all existing tiddlers exclude tiddler
by one or more defined tags.

For example:
<<list filter [tag[ALL]] [!tag[systemConfig]] [!tag[[admin]]>>


Info - I found and checked already:
1. http://lewcid.org/2007/10/23/how-to-list-tiddlers-by-tags-the-filter-tipped-way/
2. Thread: List filter & multi-word tags

thanks a lot for any advice, thread, solution, ...

regards
mammut

Try this plugin:
http://www.TiddlyTools.com/#MatchTagsPlugin

It extends the core's filterTiddlers() function so you can create
complex tag matching criteria using *boolean operators* ('and', 'or',
'not', plus nested parentheses if needed) as well as *regular
expressions* (to match 'wildcard' or other patterned tag values).

Using your example from above, you could write:

<<list filter [tag[not(systemConfig or admin)]]>>

Note: for shorter notation, you can use "&&" for AND, "||" for OR and
"!" for NOT, like this:

<<list filter [tag[!(systemConfig||admin)]]>>

enjoy,

Thanks a lot Eric, you´re great!

Just a short addition for all with same problem/desire ...
add '' '' to finish the statement finally

Example:

<<list filter "[tag[not(systemConfig or admin)]]">>

Thanks!

oops! You are absolutely right. The boolean tag matching contains
spaces, so it has to be surrounded by quotes in order for the macro to
treat it as a single parameter.

Thanks, Eric. I was just going to ask for help with this myself. [It
would be nice if there were such synchronicities every time I want
help with something.]
