For sensitive data or frequently used configurations, this can be cumbersome and insecure.\n\n### Proposed Solution\n\nAdd support for reading configuration values from environment variables with a naming convention like `FIRE_\u003cPARAM_NAME\u003e`.\n\n### Example Usage\n```markdown\npython import fire\n\ndef deploy(api_key, region='us-east-1'):\n    \"\"\"Deploy application\"\"\"\n    print(f\"Deploying to {region} with key {api_key}\")\n\nif __name__ == '__main__':\n    fire.Fire(deploy)\n```\n\nCurrent usage (exposes secret):\n```markdown\n‍‍python deploy.py --api-key=secret123 --region=eu-west-1\n```\n\nProposed usage:\n```markdown\nexport FIRE_API_KEY=secret123\npython deploy.py --region=eu-west-1\n```\n\n### Benefits\n\n- Security: Sensitive data not exposed in process lists\n- Convenience: Reduce repetitive argument typing\n- DevOps: Better integration with container/cloud environments\n\n### Alternative Considered\nUsing config files, but environment variables are more standard in modern deployment workflows.\n\n\n","author":{"url":"https://github.com/markrahimi","@type":"Person","name":"markrahimi"},"datePublished":"2025-11-14T11:05:49.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/634/python-fire/issues/634"}
