7.1. Logging to terminal

On this example we show how to make all log messages show in the terminal.

# Imports

from uuid import uuid4
from tempfile import gettempdir
from os.path import join
from aequilibrae.utils.create_example import create_example
from aequilibrae import logger
import logging
import sys

We create the example project inside our temp folder

fldr = join(gettempdir(), uuid4().hex)
project = create_example(fldr)

With the project open, we can tell the logger to direct all messages to the terminal as well

stdout_handler = logging.StreamHandler(sys.stdout)
formatter = logging.Formatter("%(asctime)s;%(name)s;%(levelname)s ; %(message)s")
stdout_handler.setFormatter(formatter)
logger.addHandler(stdout_handler)

project.close()

Out:

2021-02-18 10:19:02,988;aequilibrae;INFO ; Closed project on /tmp/ad3d3bc53843440eab7597c7a255d747
