The one by Tobias is an updated version of the second one made after some
features were added that let you add the new tag and remove the old tag
from a list of tiddlers with a single action. Most of the complexity comes
from making it look nice and making it so that the language can be changed.
The benefit is that you only have to click one button for all of them.
The part that does the work is equivalent to a tiddler with this content:
Tag to replace: <$edit-text tiddler='$:/temp/FindAndReplaceTags' field=
'find' placeholder='Tag to replace'/>
New tag: <$edit-text tiddler='$:/temp/FindAndReplaceTags' field='replace'
placeholder='New tag'/>
<$button>Find and Replace Tags
<$list filter='[tag{$:/temp/FindAndReplaceTags!!find}]'>
<$fieldmangler>
<$action-sendmessage $message='tm-remove-tag' $param={{$:/temp/
FindAndReplaceTags!!find}}/>
<$action-sendmessage $message='tm-add-tag' $param={{$:/temp/
FindAndReplaceTags!!replace}}/>
</$fieldmangler>
</$list>
</$button>
Tiddlers affected:
<$list filter='[tag{$:/temp/FindAndReplaceTags!!find}]'/>
which is hopefully a bit easier to understand.
Or if you want something much more complex for some reason you could use
this. <http://ooktech.com/jed/ExampleWikis/Version518Fun/> But that is far
more complex than you probably need. I also need to finish that at some
point.
