Thomas,
I checked the code, if you delete tid-2, it will try to create tid-3, but
as there is a tid-3, it creates tid-3 1
SO there is no risk of overwriting.
I can add extra code to check the existence and and if it exist it
increment the number to find the next empty number!
This way you can even find which tiddlers have been deleted.
See below
\define newTitle() myTiddler-{{{[tag[myTag]count[]add[$(inc)$]]}}}
\define newTiddler(n:0)
<$set name="inc" value={{{ [<__n__>add[1]] }}}>
<$wikify name="myTitle" text="<<newTitle>>" >
<$list filter="[<myTitle>] +[!has[title]]"
emptyMessage=""" <$macrocall $name="newTiddler" n=<<inc>> /> """>
<$action-createtiddler $basetitle=<<myTitle>> tags="myTag" />
</$list>
</$wikify>
</$set>
\end
- The list widget now checks if a tiddler with the new title is exist or
not
- If the tiddler is existed, then it increments by one and continues for
the next sequence number
- It will then create a tiddler with unique name
