Cylibev

Cylibev is Cython (and Python) bindings for libev library. The goal is to provide Cython interface to libev library without python-space interactione.

Cylibev isn't complete libev wrapper it only supports IO channels and timers, if you are looking for a more future reach library, please take a look at pyev

Example 1: Python callbacks

The only difference between Python and Cython mode is how callbacks work.

>>> import ev

>>> def my_timer_cb(timer, events):
...     print 'Timedout!'

>>> timer = ev.Timer(1., cb=my_timer_cb)
>>> timer.start()
>>> ev.main()

Example 2: Cython subclassing

# cython
cimport ev

cdef class MyTimer(ev.Timer):
    cdef event_handler(self, int revents):
         print 'Timedout'

timer = ev.MyTimer(1.)
timer.start()
ev.main()

Example 3: Low-level C-callbacks

# cython
cimport ev

cdef class MyObject:
     def __init__(self):
         self.timer = ev.Timer(1.)
         self.set_ccallback(<ev.watcher_cb>self.timer_event,
                            <void *> self)
         self.start()

     cdef void timer_event(self, ev.IO io, int event) except *:
          print 'Timedout'

obj = MyObject()
ev.main()
