Project Description
# crython [![Build Status](](
crython is a lightweight task (function) scheduler using [cron]( expressions written in python.

### Status
This module is currently under development.

### Installation
To install crython, simply:
$ pip install crython

### Usage
Crython supports seven fields (seconds, minutes, hours, day of month, month, weekday, year).

Call a function once a minute:
import crython

#Fire once a minute.
def foo():
print "... while heavy sack beatings are up a shocking nine hundred percent?"

Call a function every ten seconds:
#Fire every 10 seconds.
def foo():
print "I'm a big four-eyed lame-o and I wear the same stupid sweater every day."

Call a function with a single cron expression:
#Fire every 10 seconds.
def foo():
print "Hail to the thee Kamp Krusty..."

Call functions with a full cron expression:
#Fire once a week.
@crython.job(expr='0 0 0 * * 0 *')
def foo():
print "Back in line, maggot!"

Call functions with positional and/or keyword arguments:
#Fire every second.
@crython.job(second=0, 10, 20, name='Homer Simpson')
def sum(x, y, name):
print "Hello {0}. The sum is {1}".format(name, x+y)

Call functions with [predefined keywords](
#Fire once a day.
def foo():
print "That's where I saw the leprechaun. He tells me to burn things!"

Start the global job scheduler:
if __name__ == '__main__':

### TODO
- Keyword support (yearly, weekly, daily, etc)
- Support "L", "W" and "#" specials.
- Determine time delta from now -> next time expression is valid.

### Contributing
If you would like to contribute, simply fork the repository, push your changes and send a pull request.

### License
Crython is available under the [MIT license](

### See Other
There are similar python cron libraries out there.
