[tw5] Re: Links within fields
Eric / Tony, As always, thank you so much. Everything you both said makes perfect sense. I appreciate the input very much. Thanks to both of you, I'm learning a great deal about Tiddlywiki.

[tw5] Re: Links within fields
Just to note
<$list filter="[tag{!!somefield}}]">...
should be
<$list filter="[tag{!!somefield}]">...
But Erics argument is important. Keeping links as native urls also allows
you to use the html
Open
Note in the above link the "target" parameter is not in use, but can be
used to direct the opening of links in a named tab
eg; try this on tiddlywiki.com, click one, return click the other.
https://tiddlywiki.com/#Filter%20Operators; target="tiddlywiki" >
Filter Operators
https://tiddlywiki.com/#Messages; target="tiddlywiki" > Messages
- You can always bypass this with open in new window
- Or control-click to not navigate to the new tab
This allows you to reuse the same tab, and also uses pasted permalinks with
no edit
Regards
Tony

If the field value is just a single tiddler title, I'd skip putting in the
square brackets, since they might get in the way later on if you want to
pass the field value as a parameter to a widget or use it in a filter.
For example:
<$action-setfield $tiddler={{!!somefield}} text="foobar" />
or
<$list filter="[tag{!!somefield}}]">...
In both of these cases, if the square brackets were already part of the
field value, then you wouldn't get the results you'd expect.
The first case would write to a tiddler that has literal square brackets in
it's title, and the second case would look for a tag that had
square brackets in the tag value.
In any case, to make a link from a field value is pretty easy. All of the
following will work:
<$link to={{!!somefield}}><$text text={{!!somefield}}/>
or
<$tiddler tiddler={{!!somefield}}><$link/>
or even
{{{ [{!!somefield}] }}}
enjoy,
-e
