Like `subprocess.run`, but with the ability to pipe `stdout` and/or `stderr` to a `Logger` or capture each stream independently while the process is running.

run_with_logger

Like subprocess.run, but with the ability to pipe stdout and/or stderr to a Logger or capture each stream independently while the process is running.

Examples

Log stderr and capture stdout

The main process will wait for the subprocess while:

• forwarding stderr line by line to the logger
• capturing stdout in a CompletedProcess object, which is returned when the process finishes

from run_with_logger import run_with_logger
from logging import getLogger

logger = getLogger(__name__)

completed = run_with_logger(
    args=['foo', 'bar'],
    logger=logger,
    stdout_action="capture",
    stderr_action="log",
    check=False,
)

print(completed.stdout)

Log stdout and discard stderr

The main process will wait for the subprocess while:

• forwarding stdout line by line to the logger
• discarding stderr

from run_with_logger import run_with_logger
from logging import getLogger

logger = getLogger(__name__)

completed = run_with_logger(
    args=['foo', 'bar'],
    logger=logger,
    stdout_action="log",
    stderr_action="discard",
    check=False,
)

print(completed.stdout)
