Automatic creation of Tiddler on Save?

[AJ Ferrari]

Sorry for the newbie question.

Is there a way to automatically create a tiddler, based on a link in an existing tiddler.

For example

If I have a tiddler which includes

[[Restaurants]]

When I save the tiddler, a new empty tiddler is created called "Restaurants"

I saw this done in Stroll, but wanted to know how I might do this in my basic Tiddler.

Perhaps there is a standalone plugin which does this?

Thanks for any help!

Creating an empty tiddler if [[thing inside]] doesn't exist when you click on the link is the default behaviour in tiddlywiki.

Yes - so I want to override that default behaviour and automatically create [[thing inside]] when I hit save.
I've seen this done in "Stroll" but would like to know how it is done.

While this is true, it's not what the OP was asking.  Specifically,  he wrote:

"When I save the tiddler, a new empty tiddler is created.."

In other words, a new tiddler is created as soon as you save

the tiddler in which the missing link occurs, not when you

subsequently click on the link to the missing tiddler.

In Stroll, its done via $:/.giffmex/ui/EditTemplate, which redefines the save-tiddler-actions() macro like this:

\define save-tiddler-actions()
<$action-sendmessage $message="tm-add-tag" $param={{{ [<newTagNameTiddler>get[text]] }}}/>
<$action-deletetiddler $tiddler=<<newTagNameTiddler>>/>
<$action-sendmessage $message="tm-add-field" $name={{{ [<newFieldNameTiddler>get[text]] }}} $value={{{ [<newFieldValueTiddler>get[text]] }}}/>
<$action-deletetiddler $tiddler=<<newFieldNameTiddler>>/>
<$action-deletetiddler $tiddler=<<newFieldValueTiddler>>/>
<$action-sendmessage $message="tm-save-tiddler"/>
<$list filter="[all[current]links[]is[missing]]"><$action-createtiddler $basetitle=<<currentTiddler>>/></$list>
\end

Note the last line of the macro:

<$list filter="[all[current]links[]is[missing]]"><$action-createtiddler $basetitle=<<currentTiddler>>/></$list>

When this is invoked, it uses a $list widget to scan the tiddler's links for any that are missing,

and then triggers $action-createtiddler for each missing tiddler title.

To add this handling to your own TW document, copy these two tiddlers from https://giffmex.org/stroll/stroll.html:

$:/.giffmex/ui/EditTemplate

$:/config/ui/EditTemplate

enjoy,

I'm just curious - when is this useful, considering that the new tiddler/s are just empty?

IMO it would be more useful if one could add some data already at definition, like e.g

[[title:tags:text]] or [[title][tags][text]] or some such.

In addition to creating these one would probably also want them to be converted into a normal link, i.e so 

[[title][tags][text]] becomes just the normal [[title]]

It's useful in the context of Stroll -- the new tiddler will automatically show backlinks to the "parent" tiddler.

Ah, thanks Mark.

Wow - thanks.
I'm new to this software and community - its amazing, the power of this little thing! :-)

If I'm creating a new tiddler - which is a group of people in my club, it might look like this

Club tiddler

[[Bob]]
[[Sally]]
[[Ted]]

When I save, I would like to have 3 new Tiddlers automatically created - so that I can later add information about them. They will also show up in my "map" = which is how I like to navigate my tiddler.

So, it basically saves me 3 steps, of manually creating those tiddlers.

Maybe, there is an easier way to do this - I'm not sure

All I did was dig into Dave Gifford's "Stroll" code to see how he did it.

and yes... the TiddlyWiki software has remarkable abilities, but the real power

is in the community of *helpful* users and developers surrounding that software.

AJ,

Remember although the tiddler is "missing" with a new link, that title is now "live" in your wiki. It can be found.

To add to your library of approaches when you do click on a missing link and it opens a tiddler "that is missing", 

and you get the offer to edit it. 

Missing tiddler "tiddlername" – click  to create

In this case if you have a tiddler tagged $:/tags/ViewTemplate that conditionally displays (with a List asking if [all[current]is[missing]]) on all missing tiddlers,

Using a view template you can add information, buttons and more to assist in the creation of the new tiddler. This could allow a more considered approach to creating the tiddler such as indicating what it is eg person, their phone number etc...
