## Demonstrate usage of logging
#
# PyPSA uses the Python standard library [logging](https://docs.python.org/3/library/logging.html).
#
# This script shows how to use it and control the logging messages from different modules.
#
# Available as a Jupyter notebook at https://pypsa.readthedocs.io/en/latest/examples/logging-demo.ipynb.

# logging.basicConfig() needs to be called BEFORE importing PyPSA

# The reason is that logging.basicConfig() can only be called
# once, and it is already called in pypsa.__init__.py; further
# calls are ignored.

# Choices are ERROR, WARNING, INFO, DEBUG

import logging

logging.basicConfig(level=logging.ERROR)

import os

import pypsa

csv_folder_name = (
    os.path.dirname(pypsa.__file__) + "/../examples/ac-dc-meshed/ac-dc-data/"
)
network = pypsa.Network(csv_folder_name=csv_folder_name)

out = network.lopf()

out = network.lpf()

# now turn on warnings just for OPF module
pypsa.opf.logger.setLevel(logging.WARNING)

out = network.lopf()

# now turn on all messages for the PF module
pypsa.pf.logger.setLevel(logging.DEBUG)

out = network.lpf()

# now turn off all messages for the PF module again
pypsa.pf.logger.setLevel(logging.ERROR)

out = network.lpf()
