Description:

panaetius 2.3.5

Panaetius
This package provides:

Functionality to read user variables from a config.yml or environment variables.
A convenient default logging formatter printing json that can save to disk and rotate.
Utility functions.

Config
options
skip_header_init
If skip_header_init=True then the config_path will not use the header_variable as the
sub-directory in the config_path.
E.g
CONFIG = panaetius.Config("tembo", "~/tembo/.config", skip_header_init=True)
Will look in ~/tembo/config/config.yml.
If skip_header_init=False then would look in ~/tembo/config/tembo/config.yml.
Module
Convenient to place in a package/sub-package __init__.py.
See Tembo for an example: https://github.com/tembo-pages/tembo-core/blob/main/tembo/cli/__init__.py
Example snippet to use in a module:
"""Subpackage that contains the CLI application."""

import os
from typing import Any

import panaetius
from panaetius.exceptions import LoggingDirectoryDoesNotExistException

if (config_path := os.environ.get("TEMBO_CONFIG")) is not None:
CONFIG: Any = panaetius.Config("tembo", config_path, skip_header_init=True)
else:
CONFIG = panaetius.Config(
"tembo", "~/tembo/.config", skip_header_init=True
)

panaetius.set_config(CONFIG, "base_path", "~/tembo")
panaetius.set_config(CONFIG, "template_path", "~/tembo/.templates")
panaetius.set_config(CONFIG, "scopes", {})
panaetius.set_config(CONFIG, "logging.level", "DEBUG")
panaetius.set_config(CONFIG, "logging.path")

try:
logger = panaetius.set_logger(
CONFIG, panaetius.SimpleLogger(logging_level=CONFIG.logging_level)
)
except LoggingDirectoryDoesNotExistException:
_LOGGING_PATH = CONFIG.logging_path
CONFIG.logging_path = ""
logger = panaetius.set_logger(
CONFIG, panaetius.SimpleLogger(logging_level=CONFIG.logging_level)
)
logger.warning("Logging directory %s does not exist", _LOGGING_PATH)

This means in ./tembo/cli/cli.py you can
import tembo.cli

# access the CONFIG instance + variables from the config.yml
tembo.cli.CONFIG

Script
Create ./config/config.yml in the same directory as the script.
In the script initialise a CONFIG object:
import pathlib

import panaetius

CONFIG = panaetius.Config(
"teenagers_scraper", str(pathlib.Path(__file__).parents[0] / ".config"), skip_header_init=True
)

Set variables in the same way as the module above.
quickstart logging
import panaetius

def get_logger():
logging_dir = pathlib.Path(__file__).parents[0] / "logs"
logging_dir.mkdir(parents=True, exist_ok=True)

CONFIG = panaetius.Config("training_data_into_gcp", skip_header_init=True)
panaetius.set_config(CONFIG, "logging.level", "DEBUG")
panaetius.set_config(CONFIG, "logging.path", logging_dir)
return panaetius.set_logger(CONFIG, panaetius.SimpleLogger(logging_level=CONFIG.logging_level))

Utility Functions
Squasher
Squashes a json object or Python dictionary into a single level dictionary.
