timer2 Description

Scheduler for Python functions timer2 is a Python module that lets you schedule Python functions at specific times, or at an interval. It can be used as a replacement to threading.Timer, the difference is that timer2 is always only using a single thread (unless you manually start more of them)You should never use this to apply expensive operations, as this would not be effective when running in a single thread, rather you should make the timer move the operations to a execution pool (like a thread/multiprocessing pool, or maybe sending a message):>>> pool = multiprocessing.Pool()>>> timer2.apply_after(10000, pool.apply_async, (expensive_fun, ))DocumentationTimer is using Sphinx, and the latest documentation is available at GitHub: http://ask.github.com/timer2InstallationYou can install timer2 either via the Python Package Index (PyPI) or from source.To install using pip,: pip install timer2To install using easy_install,: easy_install timer2If you have downloaded a source tarball you can install it by doing the following,: python setup.py build# python setup.py install # as rootExamplesApply function after n msecs:>>> import timer2>>> timer2.apply_after(msecs, fun, args, kwargs, priority=0)Apply function every n msecs:>>> timer2.apply_interval(msecs, fun, args, kwargs, priority=0)Apply function at a specific date (a datetime object):>>> timer2.apply_at(datetime, fun, args, kwargs, priority=0)Cancelling timersThe apply_* functions returns a timer2.Entry instance, you can use this to cancel the execution:>>> tref = timer2.apply_after(msecs, fun, args, kwargs)>>> tref.cancel()Running custom Timer threadsWhen using the module interface a default timer thread is started as soon as you schedule something. If you want to keep track of the thread manually, you can use the timer2.Timer class:>>> timer = timer2.Timer()>>> timer.apply_after(msecs, fun, args, kwargs)>>> timer.stop() # stops the thread and joins it.Bug trackerIf you have any suggestions, bug reports or annoyances please report them to our issue tracker at http://github.com/ask/timer2/issues/ContributingDevelopment of timer2 happens at Github: http://github.com/ask/timer2You are highly encouraged to participate in the development.
