subprocessor 0.9.0

Run a subprocess with callbacks

Run a command in a subprocess and yield lines from stdout and stderr

Examples:

from subprocessor import Call

for is_error, line in Call('ls foo bar NO_EXIST'):
    print(is_error, line)

cmd:

A list or tuple of strings, or a string.

If shell=True, Popen expects a string, so if cmd is a list, it is joined with spaces.

If shell=False, Popen expects a list of strings, so if cmd is a string, it is split using shlex

out:

out is called for each line in the subprocess’s stdout

err:

err is called for each line in the subprocess’s stderr

sleep:

How long to sleep between checking the processes, in seconds

count:

Maximum number of lines to retrieve at a time from the streams stdout and stderr. If count is empty, retrieve lines until the stream blocks.

kwds:
