How to delete selected tiddlers from a forEachTiddler list?

[tigger6333]

If I have a list of tiddlers created by forEachTiddler,
how can I have a check box or button next to each listing which
will allow me to delete the tiddlers I want?

I have been unable to find a plugin or work out some code to do it.

Cheers

While not actually a direct answer to your question...

You can select and delete multiple tiddlers at once, using:

Thanks Eric.
I can't see how that deletes tiddlers, rather manipulates them.
I am looking into deleteAllTagged as a possible solution to my
problem.

There's a "delete tiddlers" push button right in the Tweaker (in
between the "display tiddlers" and "update tiddlers")...

Select the tiddlers you want to delete (try using the "tags" auto-
select command) ... press the "delete tiddlers" button... confirm the
"are you sure?" warning... the tiddlers are deleted. QED.

If you like, I could write a simple DeleteTiddlersMacro - that might
work like this:
<<deleteTiddlers [[tiddler title]]>>
You could then integrate that macro into your FET call.
Not sure whether I'll get to look into this today though...

Nearly got it sorted with deleteAllTaggedPlugin.
Just have to get a refresh to happen after the deletion,
and find out how to control the title of the delete button.

Latest progress is here:

You need the toDoList beta link downloaded.

Once again the power of the group is displayed!
Thanks so much for your replies.

Well, I've created this plugin anyway - it was rather easy:
http://fnd.lewcid.org/svn/TiddlyWiki/plugins/DeleteTiddlersMacro.js
(There's an odd bug that I couldn't figure out yet; the confirmation
prompt opens a new browser window/tab.)

Within FET, you could use it like so:
<<forEachTiddler
write '"<<deleteTiddlers [[" + tiddler.title + "]]>\>"'
>>

HTH.

Thanks!! My novice skills are not sure how I can use it yet, but
I am really grateful for your help.

Well, you said you wanted a "button next to each listing which
will allow me to delete the tiddlers I want" - and this pretty much does
exactly that (see the FET code in my previous post).

Let me know if you need further assistance.

Yes!! Got it.
And no browser window openong in FF2.
Maybe got something to do with refresh command.

Here's the link to get my latest with your helpful code in.

Right click save the todolistdemo.

If I want the button to say something like Confirm Delete
instead of the tiddler name, how do I do that?

thanks again FND.
That's terrific!!

It was a stupid, stupid mistake on my part (I used the HTML target
attribute without considering the consequences).
I've uploaded the fixed version to my repository:
http://fnd.lewcid.org/svn/TiddlyWiki/plugins/DeleteTiddlersMacro.js

> And no browser window openong in FF2.

Odd, it should have done that - except maybe if you have disabled
popups? Anyway, it's nothing to worry about.

I couldn't be bothered to include parameters for those things (yet), so
try this slightly altered version:
http://tiddlywiki.pastebin.com/f34cb54bd
To change the button label, modify the following line to your liking:
label: "delete",

That's not working I'm afraid. Maybe the file got corrupted somehow?
Either way, glad it works for you.

HTH.

Thanks for the versatility!
