Display tiddlers corresponding to a list of tags

[Didier Bretin]

Hello,

Is there a simple way to display tiddlers which correspond to a list of tags ?

For example if I have the following tiddlers:

- Ta (tags : T1, T2)

- Tb (tags : T1)

- Tc (tags : T2, T3)

- Td (tags : T1, T2, T3)

And I want to display all tiddlers with tags : T1 and T2 and not T3.

How can I do this ?

Regards.

You need to use tiddlywiki filters:

https://tiddlywiki.com/#Filters

A filter that accomplishes what you want is:

[tag[T1]tag[T2]!tag[T3]]

If you type that in the "fitlers" tab of the advanced search tiddler, you will see a list of the tiddlers you want.

If you want to display these results in another tiddler, there is the very handy list-links macro:

https://tiddlywiki.com/#list-links%20Macro

Which you can use like this:

<<list-links "MY FILTER HERE">>

So for you, it would look like this:

<<list-links "[tag[T1]tag[T2]!tag[T3]]">>

Like this:

[tag[T1]tag[T2]!tag[T3]]

filters in tiddlywiki are very similar to set operations. I made some notes about translating logic statements into filters that may be useful here https://ooktech.com/jed/ExampleWikis/FilterLogicExamples/

Thats a great resource Jed! Tobias also has (a more advanced) one:

Nice work Jed putting it in terms of logic.

Jed,

AM i Missing something or have you some typos in your page at  https://ooktech.com/jed/ExampleWikis/FilterLogicExamples/

You say

Operation	Symbol
A and B	A+B
A or B	A.B

But then 

 And Begins

A.B

And Or begins

A+B 

It may not be correct under NOR and XOR but I am seeking clarification before I try and work that out.

Thanks 

Tony

Oh yes, and and or are backwards in the table. Now I need to figure out where I have the original so I can upload a corrected version. I just did a quick check and it looks like it is consistent everywhere else and just the table has it backwards.

Thanks

For some a logical model is a great way to learn TiddlyWIkis filter.
