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:

import os

import panaetius
from panaetius.exceptions import LoggingDirectoryDoesNotExistException


if (config_path := os.environ.get("TEMBO_CONFIG")) is not None:
    CONFIG = 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

Utility Functions

Squasher

Squashes a json object or Python dictionary into a single level dictionary.
