data EventStream
Arguments
| :: [FilePath] | The paths to watch |
| -> Double | Latency |
| -> Bool | Process event immediately if no other events received for at least latency |
| -> Bool | Ignore events caused by current process |
| -> Bool | Get file-level notifications instead of directory level |
| -> (Event -> IO a) | The action to run when an event has taken place |
| -> IO EventStream | The event stream, use this to destroy the stream |
Create an FSEvents watch for a list of paths.
The callback action will be called for each event in the watched paths
until the EventStream is destroyed again. All callbacks are from a
single thread, so if you take too long to process an event, further
events will be delayed.
Note: it's relatively expensive to create a watch, since each watch
uses an operating system thread for its event loop.
eventStreamDestroy :: EventStream -> IO ()
Destroy an event stream, the callback action will not be run for new events (but there may be pending events remaining)
