Transclusion Filter for specifying character limit and raw transclusion

[Raghu Veer S]

As the title says, I want to transclude contents of one tiddler into another but limit the number of characters that are transcluded, meaning, when I transclude a tiddler I want to be able to specify the number of characters to be shown in the new tiddler. Also strip the formatting from the content that is transcluded. Is there a way to achieve something like that?

An example would be: <$transclude tiddler="Tiddler1" characterlimit="100" mode=raw />

If Tiddler1 looks like this:

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam,
quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo
consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse
cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non
proident, sunt in culpa qui officia deserunt mollit anim id est laborum.

quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo
consequat. duis aute irure dolor in reprehenderit in voluptate velit esse
cillum dolore eu fugiat nulla pariatur. excepteur sint occaecat cupidatat non
proident, sunt in culpa qui officia deserunt mollit anim id est laborum.

When I say <$transclude tiddler="Tiddler1" characterlimit="100" mode=raw /> in Tiddler2, It should only transclude:

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
tempor incididunt ut labore

And mode=raw should be able to strip all the formatting from the original tiddler and only fetch the text without any markups. Any help is appreciated.

Hi,

What if  Tiddler1 contains {{Tiddler2}} and Tiddler2 contains the "lorem ipsum" stuff?

and you say: <$transclude tiddler="Tiddler1" characterlimit="100" mode=raw />

You'd see: {{Tiddler2}} Is that OK for you?

There are some discussions here in the group. But I can't find them atm.

@Others may jump in here!

Hi Raghu

Here’s a macro that gets close to what you want:

\define show-extract(title)

<$wikify name="output" text={{$title$}} mode="block" output="text">

<$text text={{{ [<output>split[]first[500]join[]] }}}/>

</$wikify>

\end

<<show-extract "HelloThere">>

Transclusions will be respected (ie you’ll see the content of the transcluded tiddler, and not the {{}} markup). The problem is that all the text will appear to be on one line.

That can be fixed with some CSS:

<div style="white-space:pre;">

<<show-extract "HelloThere">>

</div>

Best wishes

Do you mean the problem that could arise as a result of a loop between the two tiddlers if they transclude each other? If that's the case, that's why I proposed a mode=raw, where the markup is stripped off, thereby eliminating any issues due to loop. I'm sorry if this was not what you meant.

Thanks a lot Jeremy! Exactly what I wanted. 😀

Although it is working separately, I am unable to get it to work with reflink tidller in TiddlyBlink:

\define mycrit() (?i)\b$(searchspx)$\b

<hr>

<div class="linkstothisnote">
<h3>Links to this note</h3>

<$vars searchme=<<currentTiddler>> searchspx={{{ [<currentTiddler>escaperegexp[]]}}} >

<div class="ln-wrapper">
  <$list filter="[!is[system]all[current]backlinks[]!tag[hide]sort[title]] -[is[current]]">
  <div class="ln-group">
    <$link>
      <p class="ln-title"><$view field="title" /></p>
      <p class="ln-excerpt"><<show-extract "title">></p>   <------------ This is how I am trying to use it, but nothing is appearing in other tiddlers. How can I pass the title to show-excerpt macro?
   </$link>
 </div>
</$list>
</div>
</$vars>
</div>

Hi Raghu

Instead of <<show-excerpt "title">>, try:

<$macrocall $name="show-excerpt" title={{!!title}}/>

Best wishes

Jeremy.
