Hello,
I wrote some very simple helper functions to work with tasklets, and I
thought they might be useful for someone.
It has a sleep function that uses a thread to block and avoid busy waiting.
An interactive console that spawn tasklets in the foreground or
background (using a thread).
Functions for spawning tasklets:
* tasklet -> creates a tasklet that you can join to and get
its return value
* thread -> same as 'tasklet' but creates it in another
thread. (useful for blocking tasklets)
* interval -> creates a tasklet that runs a function at each
specified interval of time
* loop -> creates a tasklet that runs a function in a loop
* later -> creates a tasklet scheduled to run after specified time
You can join a tasklet and get its result.
----------------------------------------------------
from useless import thread, join
def f(x):
# do something useful
t = thread(f, x)
# ...
result = join(t)
----------------------------------------------------
Stop a running tasklet created with 'interval' or 'loop'.
----------------------------------------------------
from useless import loop, stop
def f(x):
# do something useful
t = loop(f, x)
# ...
stop(t)
----------------------------------------------------
etc..
There's not documentation yet, but there are some simple examples on
the repository
and the main module is only 230 lines of code with docstrings.
The code is at https://bitbucket.org/pyalec/useless
Cheers,
Alejandro Castillo
