{"id":8816,"library":"aiopath","title":"aiopath: Async pathlib for Python","description":"aiopath provides an asynchronous implementation of Python's standard `pathlib` module, enabling non-blocking file system operations within `asyncio`, `trio`, and other `async`/`await` compatible frameworks. It mirrors `pathlib`'s API, making it familiar for users who need to perform I/O-bound tasks concurrently without blocking the event loop. The library is currently at version 0.7.7 and maintains an active development, addressing compatibility with newer Python versions and bug fixes.","status":"active","version":"0.7.7","language":"en","source_language":"en","source_url":"https://github.com/AlexDeLorenzo/aiopath","tags":["async","pathlib","filesystem","aiofiles","anyio"],"install":[{"cmd":"pip install aiopath","lang":"bash","label":"Install stable version"}],"dependencies":[{"reason":"Provides asynchronous file I/O backend.","package":"aiofile","optional":false},{"reason":"Provides a consistent async I/O interface across different event loops.","package":"anyio","optional":false},{"reason":"For type hints on Python versions prior to 3.10.","package":"typing-extensions","optional":true}],"imports":[{"note":"This is the primary class for asynchronous path operations, mirroring `pathlib.Path`.","symbol":"AsyncPath","correct":"from aiopath import AsyncPath"}],"quickstart":{"code":"import asyncio\nfrom aiopath import AsyncPath\nfrom pathlib import Path\nimport os\n\nasync def main():\n    # Ensure a directory for testing exists\n    test_dir = AsyncPath(\"aiopath_test_dir\")\n    if await test_dir.exists():\n        await test_dir.rmdir()\n    await test_dir.mkdir()\n\n    file_path = test_dir / \"my_async_file.txt\"\n    content = \"Hello, async world!\\nThis is a test.\"\n\n    # Write text asynchronously\n    await file_path.write_text(content)\n    print(f\"Wrote to {file_path.name}:\")\n\n    # Read text asynchronously\n    read_content = await file_path.read_text()\n    print(f\"Read from {file_path.name}:\\n---\\n{read_content}--- \")\n\n    # Check if file exists and is a file\n    print(f\"Does {file_path.name} exist? {await file_path.exists()}\")\n    print(f\"Is {file_path.name} a file? {await file_path.is_file()}\")\n\n    # Clean up\n    await file_path.unlink()\n    await test_dir.rmdir()\n    print(f\"Cleaned up {file_path.name} and {test_dir.name}.\")\n\nif __name__ == \"__main__\":\n    asyncio.run(main())\n","lang":"python","description":"This quickstart demonstrates basic asynchronous file operations using `AsyncPath`, including creating a directory, writing text to a file, reading its content, checking its properties, and cleaning up the created files and directories."},"warnings":[{"fix":"Upgrade `aiopath` to version `0.7.0` or higher to ensure compatibility with Python 3.11 and newer.
