path-cfg-manager 0.0.3

Auto-detect project root and provide convenient path accessors for data, models, conf, and logs directories

path_cfg_manager

A lightweight Python package that auto-detects your project root directory and provides convenience functions for accessing common subdirectories (data/, models/, conf/, logs/).

How It Works

On import, path_cfg_manager determines the project root by:

1. Checking the PROJECTPATH environment variable, or
2. Locating the /src/ segment in the running script's path and using the parent as the project root.

It then automatically adds <project_root>/src to sys.path.

Installation

pip install path_cfg_manager

Or install from source:

pip install .

Usage

from path_cfg_manager import relative_data_path, relative_conf_path, local_config

# Get absolute path to a file in the data/ directory
csv_path = relative_data_path('input', 'data.csv')

# Get absolute path to a file in the conf/ directory
cfg_path = relative_conf_path('settings.yaml')

# Load and cache a JSON config from conf/
config = local_config('config.json')

API Reference

Path Functions

All path functions accept *args path components and return an absolute path.

Function	Base directory
relative_project_path(*args)	Project root
relative_data_path(*args)	<project>/data/
relative_models_path(*args)	<project>/models/
relative_conf_path(*args)	<project>/conf/
relative_logs_path(*args)	<project>/logs/

local_config(config_name='config.json') -> dict

Loads a JSON file from the conf/ directory and caches it. Subsequent calls with the same filename return the cached result.
