One "Filter query" inside Many Tiddlers

[Mohamed Amin]

Hi all,

Suppose that I've a single "Filter Query" which be used inside a lot of Tiddlers.

Is there a way to save that query inside a "separated tiddler" or "field", so If I need to change/correct it, I can change it from one single location?

For example: a query like:

QUERY="[enlist{$TdlrName$!!elements}each[aliases]get[aliases]] +[enlist-input[]trim[]each:value[]]"

1- used in one Tiddler as =
<$list filter=QUERY >
do something
</$list>

2- and in another Tiddler as =

<$set filter=QUERY variable="var">

Do another thing

</$set>

Also used in many other Tiddlers.

Now, can I implement some thing like the below, so I can put it inside all affected tiddlers?

<$list filter={{!!QueryInsideField}} >

do something

</$list>

Regards

OK, I figured it our, below is how I get it by using a Macro and "wikify" widget:

1- Put the "Query" in side a field (or tiddler) without Quotations 

query=[all[]tag[B]]

2- Create a Macro to prepare the "Transclusion" string:-

\define me()

{{!!query}}

\end

3- Excute the "Transclusion" to get the "final value" :

<$wikify name="ss" text=<<me>> >

4- Use the "final value" inside your filter :

<$list filter=<<ss>> variable="dd" >

\define me()

{{!!query}}

\end

<$wikify name="ss" text=<<me>> >

     <$list filter=<<ss>> variable="dd" >

            <<dd>> 

     </$list>

</$wikify>

Instead of

\define me()

{{!!query}}

\end

<$wikify name="ss" text=<<me>> >

     <$list filter=<<ss>> variable="dd" >

            <<dd>> 

     </$list>

</$wikify> 

You should be able to use a much simpler solution

<$list filter="[subfilter{!!query}]" variable=dd>

<<dd>>

</$list

Best wishes

Thanks a lot Mohammad, I really appreciate your answer

"subfilter" seems VERY powerful and I didn't use it before now

Thanks a agian

Probably even:

<$list filter={{!!query}}>

</$list>

The empty line is important if you want the result as a list. Note that the !!query only refers to the current tiddlers query field. In your OP you mention reusing it in any tiddler. So if you want one filter to be reused in any tiddler, you can put the filter in a separate tiddler and then refer to it as filter={{mytiddler}}.

You are welcome!

I subfilter is very powerful as you may use it in combination with other filters like

<$list filter="[subfilter{!!query}] +[limit[2]]" variable=dd>  

This will limit outputs to two items.
