A procedure to create Wikipedia links to currentTiddler, a field or something else

#1

I tinkered with procedures and transclusion and created my first procedure. :partying_face:
It makes a link to:

  • Wikipedia about the Tiddler: <<wikipedialink>>,
  • Wiki about something else: <<wikipedialink "Tiddlywiki">>
  • Wikipedia about a field-value: <$transclude $variable=wikipedialink entry={{!!foo}}/> 
\procedure wikipedialink(entry)
  <$set name="target" filter={{{ [<entry>] }}}  emptyValue=<<currentTiddler>>>
    <$let hash={{{ [<target>encodeuricomponent[]] }}}>
    <a href=`https://en.wikipedia.org/wiki/$(hash)$`  target="_blank" rel="noopener noreferrer">Wikipedia</a>
    </$let>
  </$set>
\end

Nice little tool to add to my default wiki definition !

I just modify two things :

  1. a wikipedia logo (W) as prefix to the link

  2. replace the ‘wikipedia’ term by <<target>> to show the term used in the link.

Another little trick is to use target=“wikipedia” so all links open in the same tab unless you use r-click.

That are good ideas.
Did you upload the correct json? There are 224 Tiddlers in it but not the modified procedure

oups I edited my post to correct this.

If I just choose

<<target>> as shown link there are some realy ugly cases like https://en.wikipedia.org/wiki/Phrases_from_The_Hitchhiker%27s_Guide_to_the_Galaxy#The_Answer_to_the_Ultimate_Question_of_Life,_the_Universe,_and_Everything_is_42.

I changed it and now got these possibilities.

I did not figure out how to show currentTiddler. I bet, I am missing triple brackets or somebackticks.

How do I pass <<currentTiddler>> to the procedure without the long macrocall?

If I use {{!!title}} in those cases, it looks and works fine in some wikis BUT
the 4th row each (“show currenTiddler”) is somehow corrupt. On tiddlywiki.com and tiddlyhost it mixes the links, depending on how many / are in the title. On empty.html it works fine.

I don’t understand that behavior.

The

does not work.

\procedure wikipedialink(input, topic)

<$set name="target" filter={{{ [<input>] }}}  emptyValue=<<currentTiddler>>>
    <$let hash={{{ [<target>encodeuricomponent[]] }}}>
        <a href=`https://en.wikipedia.org/wiki/$(hash)$`  target=“wikipedia” style="text-decoration:none;" rel="noopener noreferrer">{{$:/img/Wikipedia}}<<topic>></a>
    </$let>
</$set>

\end

Thats Odd, look closely at the quotes, they are not the same as elsewhere, try "wikipedia", if you dont have any luck I will review / test the code.

This seams to be a problem with CamelCase that I to stumbled upon by chance. CamelCase is activated on tiddlywiki.com and it overrules my link. Without CamelCase it works fine.

My procedure doesn’t set a “wikipedia browser tab”. If have another link with target="wikipedia" and use this first to create a browser tab “wikipedia” than my procedure will use this tab. But if the browser tab with the wikipedia site is created by my procedure than it will create a new tab for each link.

@TW_Tones Thanks for the offer! Could you have a look at the code?

  1. How can I set the target tab?
  2. How can I call the procedure to show the tidderl title? Is my use of {{!!title}} the elgetante was or could one use currentTiddler?
