title: js/TiddlerOutput.js
|
|
|
|
Serializers that output tiddlers in a variety of formats.
|
|
|
|
store.serializeTiddlers(tiddlers,type)
|
|
|
|
tiddlers: An array of tiddler objects
|
|
type: The target output type as a file extension like `.tid` or a MIME type like `application/x-tiddler`. If `null` or `undefined` then the best type is chosen automatically
|
|
|
|
The serializer returns an array of information defining one or more files containing the tiddlers:
|
|
|
|
[
|
|
{name: "title.tid", type: "application/x-tiddler", ext: ".tid", data: "xxxxx"},
|
|
{name: "title.jpg", type: "image/jpeg", ext: ".jpg", binary: true, data: "xxxxx"},
|
|
{name: "title.jpg.meta", type: "application/x-tiddler-metadata", ext: ".meta", data: "xxxxx"}
|
|
]
|
|
|
|
Notes:
|
|
* The `type` field is the type of the file, which is not necessrily the same as the type of the tiddler.
|
|
* The `binary` field may be omitted if it is not `true`
