        "description": "# pyeither\n\nA functional Python library that exposes `Data.Either` from Haskell.\n\n```haskell\ndata Either e a = Left e | Right a\n```\n\n## Example Usage\n\n```python\nimport os\nimport json\nimport either\n\ndef main():\n    path = \"~/myfile.json\"\n    \n    # Lift a normal value into Either\n    e_path = either.pure(path)\n\n    # Ensure the path is valid, returning Right(path) if it is or Left(\"not a file\") if it isn't\n    e_valid = e_path.bind(either.predicate(os.path.isfile, \"not a file\"))\n\n    # Load a file as json, returning Right(contents) if it works, or Left(exc) if it doesn't\n    e_data = e_valid.bind(lambda p: either.attempt(json.load, p))\n\n    # It's annoying to assign intermediate values to variables, so you can chain expressions\n    # Equivalent to above:\n\n    e_data2 = (either.pure(path)\n        .bind(either.predicate(os.path.isfile, \"not a file\"))\n        .bind(lambda p: either.attempt(json.load, p)))\n\n    # Python lacks do-notation, so there's not a nice equivalent syntax\n\n    # Build pipelines of actions using monadic composition\n\n    ensure_path = either.predicate(os.path.isfile, \"not a file\")\n    load_file = lambda p: either.attempt(json.load, p)\n\n    process = either.kleisli(ensure_path, load_file)\n\n    # Equivalent to above:\n    e_data3 = either.pure(path).bind(process)\n```\n\n## Getting pyeither\n\n```\npip install pyeither\n```\n\n## Motivation\n\nI've created an IPython Notebook that describes the motivation for this project\nas an interactive tutorial building an analogous system from scratch. If you're\ninterested in learning more about the **why** of this project, please check it\nout!\n\n[**Motivation Notebook**](https://github.com/SegFaultAX/pyeither/blob/master/pyeither_demo.ipynb)\n\n## Special Thanks\n\nThis library depends on the absolutely wonderful\n[`attrs`](http://www.attrs.org/en/stable/) library, without which there would\nhave been far more ugly boilerplate.\n\n## License\n\nCopyright 2018 Michael-Keith Bernard \n\nSee LICENSE.txt for the full license.",
