Cloning a Tiddler

[Mohammad]

How is it possible to clone a tiddler without navigation to it?

1. use the tm-new-tiddler
• issue: open the tiddler in the story river, not good for bulk cloning
2. use the action action-createtiddler
• issue: has to iterate over all fields and copy one by one to the new tiddler, performance issue not simple

What do you propose? Any better solution?

Mohammad,

There is an option when creating a tiddler to get the title of the new tiddler without navigating to it. See $savetitle
https://tiddlywiki.com/#ActionCreateTiddlerWidget and the differences with https://tiddlywiki.com/#WidgetMessage%3A%20tm-new-tiddler

Mohammad,

I previously created a nested list that generated a single variable containing fieldname=value fieldname2="value 2" that provided all field=value pairs.

Hi,

Have a look at :

https://groups.google.com/d/msg/tiddlywiki/swbra9EhOm4/dQk3YpsPAQAJ

Delete the part where you remove a field. The drawback is that you need to know the new title.

Hi,

 Thanks FrD, the problem is it will overwrite the existing tiddlers. I am looking to see how to clone as Tony said in his post.

Hi Mohammad,

You could try to use your first option (tm-new-tiddler) followed by a tm-close-tiddler action.

Did you already try that?

Good luck,
Thomas

Hi Thomas,
No I did not. I thought opening and closing toddler may cause flittering.
But I will try.

Per FrD

Create a unique title (possibly title plus date stamp).

Use action-setfield to create new tiddler with the new, unique title.

Hi Thomas,

 This does not work

<$button> Do it
<$list filter="[range[1,10]]" variable=item>
<$action-sendmessage $message="tm-new-tiddler" title=<<item>> tags="uu">
<$action-sendmessage $message="tm-close-tiddler" param=<<item>>/>
</$list>
</$button>

Hi Mark,

Yes, but I have to iterate over all fields. By the way I found something through this question that seems buggy

<$button> Do it

<$list filter="[range[1,10]]" variable=item>

<$action-sendmessage $message="tm-new-tiddler" title=<<item>> tags="uu">

</$list>

</$button>

No go to Advanced serach /Filter and type

[tag[uu]]

and click on the Delete button (trash bin)

All draft tiddlers remain open with no title, tgas, ....

What happened?

Seems this work to clone a tiddler batchwise

\define clone(newTid,Template)

<$action-createtiddler $basetitle=$newTid$ $savetitle="temp" />

<$list filter="[<__Template__>fields[]] -title" variable=fname >

<$set name="fval" tiddler=<<__Template__>> field=<<fname>> >

<$action-setfield $tiddler={{temp}} $field=<<fname>> $value=<<fval>> />

</$set>

</$list>

\end

Example

<$button>Clone me

<$list filter="[range[1,5]addprefix[a00]]">

<$macrocall $name=clone newTid=<<currentTiddler>> Template=testTemplate />

</$list>

</$button>

where testTemplate  is a sample tiddler with many fileds, tags, text has been cloned.

Why do you need to iterate the fields? When you make a clone by renaming the title, all the fields get cloned too. Or at least that's what happened in my test.

Thanks!

Hi,

No, you don't have to iterate over the fields ; it clones the template and gives the clone the title you pass.

Mohammad, here’s a version that works.

Note: There seems to be a bug in the documentation of https://tiddlywiki.com/#WidgetMessage%3A%20tm-close-tiddler where param is a parameter instead of $param (?)

<$button> Do it
<$list filter="[range[1,3]]" variable="item">
<$action-sendmessage $message="tm-new-tiddler" title=<<item>> tags="uu"/>
<$action-sendmessage $message="tm-close-tiddler" $param={{{[has[draft.of]field:draft.of<item>]}}}/>
</$list>
</$button>

tm-new-tiddler also has a param where you can give a template.

The action-setfield method from Mark and FrD looks also interesting, but is maybe a bit less readable if you come back to it after a few years.

Good luck!

I found the   action-setfield  method of silent cloning very interesting. I had absolutely no idea that it existed andcan't find this behaviour mentioned in docs.

I assume it works because cloning a title clones the tiddler in its context of running?

Is it a lucky side effect, or part of planned design?

Best wishes

Dear all,

 Thanks for all your help. I understood how cloning is possible and I hopw I can use it in TW-Commander.

Cheers
