Command to save the subtiddlers of a bundle tiddler as a series of JSON files
|
|
|
|
--savelibrarytiddlers <tiddler> <pathname> <skinnylisting>
|
|
|
|
The tiddler identifies the bundle tiddler that contains the subtiddlers.
|
|
|
|
The pathname specifies the pathname to the folder in which the JSON files should be saved. The filename is the URL encoded title of the subtiddler.
|
|
|
|
The skinnylisting specifies the title of the tiddler to which a JSON catalogue of the subtiddlers will be saved. The JSON file contains the same data as the bundle tiddler but with the `text` field removed.
