Is this a bug? Add tag to a tiddler

[Mohammad]

Why $checkbox adds tag to the end of tags field but $action-listops to beginning?

Why not they behave the same?

<$button> tag by button
<$action-listops $tiddler=<<currentTiddler>> $tags="+[append[done]]" />
</$button>


<$checkbox tag=done>Is it done?</$checkbox>


''Tags'': <$text text={{{[<currentTiddler>get[tags]]}}}/>

To reproduce drag and drop the attached tiddler into https://tiddlywiki.com/

and use $button and $checkbox and see the result!

For email reader, the first sentences is corrected as

[Mat]

Append = add to end

Checkbox adds a tag, not sure where, but the system sorts them.

<:-)

Mat,

 If you try the example, strangely append add tags to the beginning!

even with $tags="done" still $listops adds tag to the beginning!

Whenever I try it, no matter which way, the tag list is sorted alphabetically.

You can see this by adding a "abc" tag to the top. I think

the tag field is special, and TW takes extra steps to make sure it is sorted.

[Mohammad]

Mark have you noted to the last line of code and what it shows?

''Tags'': <$text text={{{[<currentTiddler>get[tags]]}}}/>

This shows the real order I think!

But as you said in the tags-wrapper (under subtitle) always sows them sorted!

[Mark S.]

You're right. Or almost. Using the $tags attribute with list-ops ends up sorting the list. Add tag "abc" to see the sorting.

But if you set it up this way:

<$action-listops $tiddler=<<currentTiddler>> $field="tags" $subfilter="+[prepend[done]]" />

the it will prepend "done", and if you do it this way:

<$action-listops $tiddler=<<currentTiddler>> $field="tags" $subfilter="+[append[done]]" />

it will append "done".

So I guess using "$tags" has a "feature" that the result always gets sorted.

Thanks Mark!

The tags field is always sorted by the core, sometimes this only happens when the wiki is reloaded, but the core will always sort the tags field into alphabetical order when the wiki starts, the order of the tags field at other times isn't reliable and won't be saved.

Jed, Thank you for clarification!
