title: Hook: th-renaming-tiddler
|
|
type: text/vnd.tiddlywiki
|
|
|
|
This hook allows plugins to inspect tiddlers before they are modified by the `tm-rename-tiddler` message.
|
|
|
|
Hook function parameters:
|
|
|
|
* ''newTiddler'': tiddler object incorporating the rename
|
|
* ''oldTiddler'': optional existing tiddler object that will be overwritten
|
|
|
|
Return value:
|
|
|
|
* newTiddler: tiddler object to be used for the renaming operation.
|
|
|
|
The original tiddler object can be returned unmodified by the hook. If the hook needs to modify the tiddler then it should return a new tiddler object, for example:
|
|
|
|
```
|
|
return new $tw.Tiddler(tiddler,{"my-field": value});
|
|
```
|
|
|
|
Hooks must not change the ''title'' field but can freely modify any other field of the tiddler.
