What's the purpose of mon.event_pending()? Can you use it to check whether
an event is due? Example:
import gamin
import sys
import time
directory = sys.argv[1]
def callback(path, event):
print "Got callback: %s, %s" % (path, event)
mon = gamin.WatchMonitor()
mon.watch_directory(directory, callback)
while True:
if mon.event_pending():
mon.handle_one_event()
else:
time.sleep(.1)
I didn't find anything that deserves to be called documentation, but a quick
test suggests that this at least responds to Ctrl-C:
$ mkdir alpha
$ python gamin_test.py alpha/ &
[1] 9932
$ Got callback: /home/petto/srcx/clpy/alpha, 8
Got callback: /home/petto/srcx/clpy/alpha, 9
touch alpha/beta
$ Got callback: beta, 5
Got callback: beta, 1
mkdir alpha/gamma
$ Got callback: gamma, 5
fg
python gamin_test.py alpha/
^CTraceback (most recent call last):
File "gamin_test.py", line 19, in <module>
time.sleep(.1)
KeyboardInterrupt
