@ -8,10 +8,16 @@ Install the plugin and put this in your `settings.json`:
"ep_delete_after_delay": {
"delay": 86400, // one day, in seconds
"loopDelay": 3600, // one hour, in seconds
"deleteAtStart": true,
"text": "The content of this pad has been deleted since it was older than the configured delay."
},
`delay` (mandatory) is in seconds. You can't put `7*86400` for a week, you have to put `604800`.
`delay` (mandatory) delay in seconds with no edition of the pad before deletion. You can't put `7*86400` for a week, you have to put `604800`.
`loopDelay` delay in seconds between deletion loops. Deletion loop will check all pads to see if they have to be deleted. You can't put `60*60` for a hour, you have to put `3600`. Default is one hour.
`deleteAtStart` binary, tells if you want to start a deletion loop at Etherpad startup. Default is true.
`text` is the text that will replace the deleted pad's content. Default is what is in the example above.
