not detecting files saved by Intellij IDEA ?

[simonmichael]

Thanks for hfsevents, which is used in hledger-ui via fsnotify. I am seeing events when I save a file from emacs, but not when I save it from IDEA. Here's a log from both.. any ideas ?

module Main where

import System.OSX.FSEvents
import Control.Monad
import Control.Concurrent

main = do
  es <- eventStreamCreate ["."] 1.0 True True True print
  replicateM 30 (threadDelay 10000000)
  putStrLn "destroying event stream"
  eventStreamDestroy es
  replicateM 30 (threadDelay 10000000)

~/src/hledger$ ./hfstest
[EMACS:]
Event {eventPath = "/Users/simon/src/PLAINTEXTACCOUNTING/hledger/.#a.j", eventId = 610728226, eventFlags = 262400}
Event {eventPath = "/Users/simon/src/PLAINTEXTACCOUNTING/hledger/a.j", eventId = 610728235, eventFlags = 70656}
Event {eventPath = "/Users/simon/src/PLAINTEXTACCOUNTING/hledger/.#a.j", eventId = 610728238, eventFlags = 262912}
[IDEA:]
Event {eventPath = "/Users/simon/src/PLAINTEXTACCOUNTING/hledger/.git/index.lock", eventId = 610728402, eventFlags = 65792}
Event {eventPath = "/Users/simon/src/PLAINTEXTACCOUNTING/hledger/.git/index.lock", eventId = 610728414, eventFlags = 66304}
Event {eventPath = "/Users/simon/src/PLAINTEXTACCOUNTING/hledger/a.j___jb_tmp___", eventId = 610728631, eventFlags = 71936}
Event {eventPath = "/Users/simon/src/PLAINTEXTACCOUNTING/hledger/a.j", eventId = 610728635, eventFlags = 83968}
Event {eventPath = "/Users/simon/src/PLAINTEXTACCOUNTING/hledger/a.j___jb_old___", eventId = 610728638, eventFlags = 68096}
Event {eventPath = "/Users/simon/src/PLAINTEXTACCOUNTING/hledger/.idea/workspace.xml___jb_tmp___", eventId = 610728688, eventFlags = 71936}
Event {eventPath = "/Users/simon/src/PLAINTEXTACCOUNTING/hledger/.idea/workspace.xml", eventId = 610728692, eventFlags = 83968}
Event {eventPath = "/Users/simon/src/PLAINTEXTACCOUNTING/hledger/.idea/workspace.xml___jb_old___", eventId = 610728695, eventFlags = 68096}
Event {eventPath = "/Users/simon/src/PLAINTEXTACCOUNTING/hledger/.git/index.lock", eventId = 610728701, eventFlags = 66304}

(Also, in that test program, what's the reason for destroying the event stream, and for waiting afterward ?)
