The download file message causes the current saver module to prompt the user to download the result of parsing a specified template tiddler as a file. It requires the following properties on the event object:
| Name | Description |
|---|---|
| param | Title of a tiddler to use as a template for the new tiddler |
| {any other params} | Any other parameters are made available as variables within the context of the widget message. |
The following variable names have special behaviour:
| Name | Description |
|---|---|
| filename | Filename for the downloaded file (note that this is a hint to the browser, and the actual filename used may be different) |
The download file message is usually generated with the ButtonWidget.
The download file message is handled by the TiddlyWiki core SyncMechanism which invokes the current SaverModule.
