Problem and Solution

#	Problem	Solution
1	Config values come from many sources (CLI flags, YAML files, env vars, hard-coded defaults) and ad-hoc precedence rules drift between scripts.	PriorityConfig.resolve() enforces a single direct → yaml → env → default cascade with a resolution log.
2	Runtime directories (cache, logs, sessions) get hardcoded to ~/.cache/<pkg>/ and ignore the user's $SCITEX_DIR.	get_paths() / ScitexPaths roots directories at $SCITEX_DIR; _ecosystem.local_state.runtime_path() resolves per-package <pkg>/runtime/ paths canonically.
3	.env loading is reinvented per project (cwd-only, no walk-up, silent override of process env).	load_dotenv(walk_up=True) walks parents to $HOME, never overrides existing process env, and returns a boolean status.

Quick Start

import scitex_config as cfg

config = cfg.get_config()
log_level = config.resolve("logging.level", default="INFO")

paths = cfg.get_paths()
print(paths.cache)            # ~/.scitex/cache

# SciTeX-ecosystem packages: use the per-package state resolver
from scitex_config._ecosystem import local_state
log_path = local_state.runtime_path("hpc", "dispatch.log")
print(log_path)               # ~/.scitex/hpc/runtime/dispatch.log

Python API

import scitex_config as cfg

# YAML-based (recommended)
config = cfg.get_config()
print(config.MY_KEY)
log_level = config.resolve("logging.level", default="INFO")

# Path resolution
paths = cfg.get_paths()
paths.function_cache       # ~/.scitex/cache/function/...

# Layered priority cascade (direct > yaml > env > default)
pc = cfg.PriorityConfig(yaml_path="config/app.yaml")
db_url = pc.resolve(
    direct=cli_arg,
    key="database.url",
    env_var="DATABASE_URL",
    default="sqlite:///dev.db",
)

Status

Standalone fork of scitex.config. Only dep is PyYAML. The umbrella package's scitex.config import path is preserved via a sys.modules-alias bridge.

Part of SciTeX

scitex-config is part of SciTeX. Install via the umbrella with pip install scitex[config] to use as scitex.config (Python) or scitex config ... (CLI).
