loe-simp-app-fw

A super simple python app framework that includes a logger and a config manager. This framework is also useable in Jupyter Notebook.

In addition to those function, it has a CSV IO object, a Caching object to help with common data tasks.

Example

To get started,

python3 -m loe_simp_app_fw init-repo

It will generate a project structure,

project directory
├── .gitignore
├── .cache
│   └── (Hashed file name)
├── config-framework.yaml
├── config-project.yaml
├── LICENSE
├── log
│   └── 2024-04-16.log
├── README.md
└── src
    ├── configuration.py
    └── main.py

What happens after init

In configuration.py, after the initialization, it would be,

import os

from typing import ClassVar, Literal
from loe_simp_app_fw import BaseConfig, FrameworkConfig, Logger

#---------------------------------------------------------------

# Modify the framework config location if necessary
FrameworkConfig.load(os.path.abspath("./config-framework.yaml"))


class ProjectConfig(BaseConfig):
    # Add tunable here
    example_tunable: ClassVar[str] = "ExAmPlE"

#---------------------------------------------------------------

if FrameworkConfig.developer_mode:
    # Skip loading the config
    '''
    Developer mode force the usage of the default configuration of ProjectConfig,
        i.e., the one above, rather than the one in config-project.yaml
    '''
    Logger.warning(f"Project config is now in developer mode, settings from config-project.yaml will be ignored")
else:
    # Load the config 
    ProjectConfig.load(FrameworkConfig.project_config_path)

# Combine two config
class Config(ProjectConfig, FrameworkConfig):
    pass

# Init logger
Logger(Config.log_directory, project_root_path = Config.project_directory, log_level = Config.log_level, buffering = Config.log_buffer_size)

Logger.info("Configuration finish initialization")

One may add additional tunables under ProjectConfig as a class variable.

In main.py, after the initialization, it would be

from loe_simp_app_fw import Logger
from configuration import Config

Basic Usage

Logger usage

from loe_simp_app_fw import Logger

Logger.debug("This is a debug message.")
Logger.info("This is a info message.")
Logger.warning("This is a warning message.")
Logger.error("This is a error message.")

Config usage

from configuration import Config

something = Config.log_level

.gitignore

.gitignore file will be generated for the project.

In addition to the python gitignore template from GitHub, the following are also added.
