List filter question

[David Gifford]

Hi all

I would like to create a list filter where for each tiddler:

1. you would see the tiddler's title.
2. But the tiddler title would be an external link to a relative filepath contained in a special field in that tiddler ("relativepath").

So the list results would turn up the equivalent of

[ext[Jeremy|../people/ruston.html]]

Use case: glossary of terms, where each definition is on a separate html page.

Been playing around but not getting anywhere.

Dave

[David Gifford]

Well, I cheated and went with this:

1. <$list filter="[tag[bi]sort[title]]"><$view field="title"/> <$transclude field="relativepath" mode="inline"/></$list>

2. relativepath is set up like this: <a href="./path/filename.html">(go)</a>

But if someone has a better way to do this, where the title contains the external, relative link, please let me know.

Blessings

Dave

You can use a macro to assemble the desired syntax

\define extlink(text,path) [ext[$text$|$path$]]

Put this definition into a separate tiddler, tagged with "$:/tags/Macro".

This makes the macro available for use in other tiddlers.

Then, use the $macrocall widget to invoke your macro using the values stored in the two separate fields, like this:

<$macrocall $name="extlink" text={{!!title}} path={{!!relativepath}} />

enjoy,

Thanks Eric!

Hi Dave,

 

Then, use the $macrocall widget to invoke your macro using the values stored in the two separate fields, like this:

<$macrocall $name="extlink" text={{!!title}} path={{!!relativepath}} />

 

Alternatively, put it in a template, e.g.:

title: $://extlink

\define extlink(text,path) [ext[$text$|$path$]]

<$macrocall $name="extlink" text={{!!title}} path={{!!relativepath}} />

and then...

{{Jeremy||$://extlink}}

or just

{{||$://extlink}}

...in a list widget.

Best wishes,

Tobias.

[David Gifford]

Thanks Tobias!

Hi Tobias,

Using your macro, how would I remove the title of the current tiddler, which shows up above the list filter?

Dave

[David Gifford]

Never mind, I had put the macro in both the extlink tiddler AND the tiddler in which I put the macro. Fixed.

[David Gifford]

That is, I put the /define part in both.

[Tobias Beer]

Hi David,

Let me decipher this template for you once more...

title: $://extlink

\define extlink(text,path) [ext[$text$|$path$]]

<$macrocall $name="extlink" text={{!!title}} path={{!!relativepath}} />

Means: this will be a tiddler called $://extlink which contains the last two lines.

Then, in any other tiddler, you can do:

{{Jeremy||$://extlink}}

This will take the tiddler "Jeremy" and based on its title and relativepath field will create this extlink for you.

However, if you wanted to give this link a custom text, then this will not work for you, as you cannot pass parameters to a transclusion like you can pass them to a macro. At that point, you'd want to use a(nother) macro.

Tobias.

[David Gifford]

Hi, yes, I figured that out myself. Just that I had also put the /define line in the tiddler with the macro by mistake. But I got it fixed this morning. Works great. Thanks again!

I think you meant:

<$macrocall $name="extlink" text={{!!title}} path={{!!relativepath}} />

^^^^^
Right? (text instead of title, because the Macro parameter is named "text")

Thanks

Yes, will edit the above. Thx. :-)
