Can use regex if regex is set to True coalesce: If this coalescing option is enabled, events are filtered based on their unicity, only unique events are enqueued, doublons are discarded. An event is unique when the combination of its fields (wd, mask, cookie, name) is unique among events of a same batch. After a batch of events is processed any events are accepted again. This option is top-level (at the same level as the path) and therefore affects all paths that are being watched. This is due to this option being at the Notifier level in pyinotify. r � r T�/r% �exclude� ZregexFzFailed to compile regex: %s�*)�tagr3 Zchangez Excluding %s from event for %sr r r r& r' )r �recr' N)r; r' Zexclude_filter)-r, r- r.
