This hook will allow a plug-in developer to re-write each line when exporting to HTML.

## exportFileName

Things in context:

1. padId
|
||||
|
||||
This hook will allow a plug-in developer to modify the file name of an exported pad. This is useful if you want to export a pad under another name and/or hide the padId under export. Note that the doctype or file extension cannot be modified for security reasons.
|
||||
|
||||
Example:
|
||||
|
||||
```
|
||||
exports.exportFileName = function(hook, padId, callback){
|
||||
callback("newFileName"+padId);
|
||||
}
|
||||
```
