a coroutine framework based on twisted and stackless python

Project description

twless is a coroutine framework based on twisted and stackless python.
it provide simple and nature way to create coroutining runtime envirement,no async/await, yield , callback infection and circling is needed,eveything is just straight-forward,easy to understand.

look at this simple example:

from twless.schedule import runReactor,exitReactor,startUserTasklet
from twless.context import sleepInTasklet

class TestContext:
    counter = 0

def worker(idx):
    '''

        tasklet(coroutine) execute function

    '''
    print('worker #{0} start...'.format(idx))
    # sleep 1 second and continue.
    sleepInTasklet(1)
    print('worker #{0} finish.'.format(idx))
    TestContext.counter -= 1
    if TestContext.counter <= 0:
        # when all workers finish,exit from current process.
        exitReactor()

def main():
    #
    # start up 100 tasklet(coroutine)
    for idx in xrange(100):
        startUserTasklet(worker,idx)
        TestContext.counter += 1


if __name__ == '__main__':
    runReactor(main)
