Run a subprocess with callbacks

Project description

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)
Call(cmd, sleep=0, count=None, **kwds)
An iterator for (is_error, line) pairs from a subprocess.
cmd:

A list or tuple of strings, or a string, to run in a subprocess.

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

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

sleep:
How long to sleep between checking the process, 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:
Keywords that are passed to subprocess.Popen
