hatch-dotenv 0.1.3

Hatch plugin that enables dotenv support

hatch-dotenv

A Hatch plugin that loads environment variables from .env files.

Installation

pip install hatch-dotenv

Usage

Add hatch-dotenv to your environment requirements and configure the collector for each environment:

[tool.hatch.env]
requires = ["hatch-dotenv"]

# Configure env-files for the default environment
[tool.hatch.env.collectors.dotenv.default]
env-files = [".env", ".env.local"]

# Configure env-files for other environments
[tool.hatch.env.collectors.dotenv.dev]
env-files = [".env", ".env.local", ".env.development"]

[tool.hatch.env.collectors.dotenv.production]
env-files = [".env", ".env.production"]

Works with any environment type:

[tool.hatch.env]
requires = ["hatch-dotenv", "hatch-pip-compile"]

[tool.hatch.envs.locked]
type = "pip-compile"

[tool.hatch.env.collectors.dotenv.locked]
env-files = [".env", ".env.local"]

Configuration Options

Option	Type	Default	Description
env-files	list[str]	[]	List of .env file paths to load
fail-on-missing	bool	false	Raise an error if a file is missing

Strict mode

To fail when an env file is missing, set fail-on-missing = true:

[tool.hatch.env.collectors.dotenv.default]
env-files = [".env"]
fail-on-missing = true

Behavior

• Files are loaded in order; later files override earlier ones
• Missing files are silently skipped (unless fail-on-missing = true)
• Variables from .env files override existing env-vars in config
