This is utility class to execute other program, especially easier to handle stdin/out.
What you need to do are
- to use PyExecUtil with stdout/err handler function
- or to derive
pyExecUtilclass and override onCompletion
from pyExecUtil import PyExecUtil
def my_process(args, stdout_data, stderr_data):
print(stdout_data)
print(stderr_data)
if __name__ == '__main__':
cmd = PyExecUtil("echo 'started'; sleep 2; echo 'finished'")
cmd.execute(timeout=3, onCompletion=my_process, args=None)
cmd.execute(timeout=1, onCompletion=my_process, args=None)
from pyExecUtil import PyExecUtil
class MyExtCommandHandler(PyExecUtil):
def __init__(self, cmd):
super(MyExtCommandHandler, self).__init__(cmd)
def onCompletion(self):
print(self.stdout_data)
print(self.stderr_data)
if __name__ == '__main__':
cmd2 = MyExtCommandHandler("echo 'started'; sleep 2; echo 'finished'");
cmd2.execute(timeout=3)
cmd2.execute(timeout=1)
Optinally, you can use
PyExecUtil.execute() # execute without infinite wait (no timeout specified)
PyExecUtil.terminate() # force terminate
