- Bump dependency on Black to 21.7b0 - Prefer double quotes for non-docstring triple quoted strings (GH#10) - Add support for "py39" as target-version (GH#44) - Docstrings now always use triple-double-quoted strings (GH#5)

What is blue? =============
``blue`` is a somewhat less uncompromising code formatter than ``black``, the OG of Python formatters. We love the idea of automatically formatting Python code, for the same reasons that inspired ``black``, however we take issue with some of the decisions ``black`` makes. Kudos to ``black`` for pioneering code formatting for Python, and for its excellent implementation.
Where the ``blue`` maintainers disagree with the stylistic (and unconfigurable) choices made by ``black``, we monkeypatch to change these decisions to our own liking. We intend for these differences to be minimal; even in cases where we'd prefer something different, there's a lot we can live with for the sake of consistency.
We'd prefer not to fork or monkeypatch. Instead, our hope is that eventually we'll be able to work with the ``black`` maintainers to add just a little bit of configuration and merge back into the ``black`` project. We'd be ecstatic if ``blue`` eventually were retired. Until then, we'll maintain our small set of hacks on top of ``black`` and carefully consider what other deviations are needed to assuage our sensitive, but experienced, eye.
How do I use blue? ==================
Exactly the same as you would use ``black``. Invoke and configure ``blue`` as you would ``black`` -- just replace the ``black`` command with ``blue``, sit back, and enjoy even betterly formatted Python code! You can refer to `black's https://black.readthedocs.io/en/stable/`_ documentation for anything not listed here.
So what's different? ====================
Here is a brief list of differences between ``blue`` and ``black``:
* ``blue`` defaults to single-quoted strings. This is probably the most painful ``black`` choice to our eyes, and the thing that inspired ``blue``. We strongly prefer using single quoted strings over double quoted strings for everything *except* docstrings and triple quoted strings (TQS). Don't ask us why we prefer double-quotes for TQS; it just looks better to us! For all other strings, ``blue`` defaults to single quoted strings. In the case of docstrings, those always use TQS with double-quotes.
* ``blue`` defaults to line lengths of 79 characters. Nearly every project creates a pyproject.toml just to change this one setting so making it consistent with PEP 8 seems relatively harmless.
* ``blue`` preserves the whitespace before the hash mark for right hanging comments.
* ``blue`` supports multiple config files: ``pyproject.toml``, ``setup.cfg``, ``tox.ini``, and ``.blue``.
We are `accumulating https://github.com/grantjenks/blue/issues/2`_ a list of other deviations we are considering. As we decide to implement any particular suggestion, we'll turn those into individual issues and tackle them one-by-one. If you have suggestions for other deviations from ``black``'s choices, please open a separate ticket on our tracker, and we'll see how it goes!
Why "blue"? ===========
Several reasons! If your formatter is going to beat up your code, it'll leave it black and blue, or maybe in this case, black *or* blue. Blue is better!
We also thought about "tan" because, yum! But that project name was already taken. Frankly, "blue" was also taken, but largely unused. Our thanks to Nick Ficano for donating the project namespace to us!
Blue is also the color of `LinkedIn https://www.linkedin.com/`_, the authors' gracious employer, and we intend to socialize its use within our company code base.
``blue`` thanks this list of contributors for all its wonderful goodness.
