Add/Remove Tags from Tiddler

[Steven Schneider]

Hello Old Friends:

I'm trying to write a macro that would add & remove tags from a tiddler with a single button. I've got it working with two buttons, but am quite sure I'm missing something very simple. Any suggestions would be much appreciated. Thanks, //steve.

\define makeOld()

<$fieldmangler>

Add <<tag OldTopics>> 

<$button message="tm-add-tag" param="OldTopics">{{$:/core/images/new-button}}</$button>

<br>

Remove <<tag Topics>>

<$button message="tm-remove-tag" param="Topics">{{$:/core/images/delete-button}}</$button>

</$fieldmangler>

\end

<<makeOld>>

So, you want to do the two things at the same time? This seems to work:

\define myactions()
<$fieldmangler>
<$action-sendmessage $message="tm-add-tag" $param="OldTopics"/>
<$action-sendmessage $message="tm-remove-tag" $param="Topics"></$button>
</$fieldmangler>
\end
\define makeOld()
Add <<tag OldTopics>> Remove <<tag Topics>>
<$button actions=<<myactions>>>{{$:/core/images/erase}}
</$button>
\end

<<makeOld>>

I changed the two buttons to an erase button since there is now one button to do two things. But of course you can decorate it however you want. The actions were moved to a macro and activated through the "actions" attribute of the button, which is supposed to be the new way of doing things.

Thanks, Mark. Worked perfectly!

Hm, I'm wondering, why this code doesn't work at tiddlywiki.com.

Greetings,

Works fine when I test it. Note that it doesn't toggle between the two states -- that wasn't the original request.

Hi folks,

I use the fabulous listops action for this (a bit complicated but reusable):

\define BtnTagListops(btntext,add-remove,tooltip)
<$button tooltip="""$tooltip$""">
<$wikify name="timestampState" text="{{$:/config/TimestampDisable}}">
<$action-setfield $tiddler="$:/config/TimestampDisable" $value="yes"/>
<$action-listops $tags="$add-remove$" />
$btntext$
<$action-setfield $tiddler="$:/config/TimestampDisable" $value=<<timestampState>>/>
</$wikify>
</$button>
\end

This does change tags WITHOUT updating timestamps (it stores and restores the previous setting for updating timestamps). I call it from other macros like this one:

\define todoBtnDoNow()
<$wikify name="tt" text="switch tags">
   <$macrocall $name="BtnTagListops" btntext="Do this now" add-remove="ToDoNow -ToDo" tooltip=<<tt>>/>
</$wikify>
\end

<<todoBtnDoNow>> adds the tag ToDoNow and removes the tag with the minus (-) ToDo. You could add and remove as many tags as you like.

These are somewhat simplified macros, I hope they still work and it is clear how they work.

Cheers,

Great solution Thomas. There is small typo I corrected below

\define BtnTagListops(btntext,add-

remove,tooltip)
<$button tooltip="""$tooltip$""">
<$wikify name="timestampState" text="{{$:/config/TimestampDisable}}">
<$action-setfield $tiddler="$:/config/TimestampDisable" $value="yes"/>
<$action-listops $tags="$add-remove$" />
$btntext$
<$action-setfield $tiddler="$:/config/TimestampDisable" $value=<<timestampState>>/>
</$wikify>
</$button>
\end

Calling macro

\define todoBtnDoNow()
<$wikify name="tt" text="switch tags">
   <$macrocall $name="BtnTagListops" btntext="Do this now" add-remove="ToDoNow -ToDo" tooltip=<<tt>>/>
</$wikify>
\end

In the second script (calling macro, the correct $name="BtnTagListops" instead of teBtnTagListops.

Cheers

Mohammad

Thank you, Mohammad! I corrected the typo also in my previous post, just in case anyone stops reading there.

Cheers,

A quick note - back on the original post.

The Need to remove one tag when adding another to toggle a state needs to occur everywhere in the wiki the same way or you may end up with both or neither.

This is why I tend to move it to a common field name with one of the possible values only permitted at a time.

Once you become used to has[fieldname] get[fieldname] {{!!fieldname}} has:field[fieldname]] its easier than managing tag toggles and can protect you from the inconsistencies allowing only one value at a time.
