* Document git's ignore-revs-file feature
A long-standing counterargument against moving to automated code formatters
like Black is that the migration will clutter up the output of git blame.
This used to be a valid argument, but not anymore. Since git version 2.23,
git natively supports ignoring revisions in blame with the --ignore-rev
and --ignore-revs-file options.
This isn't documented in the Black documentation. It should be as it would
put old projects wanting to migrate to Black at ease since blame won't
be ruined.
* Add links so people can +1 on --ignore-revs-file support
* Fix wording
'Counterargument' was the wrong word since it means an objection to an objection. 'Argument' is the proper word I was looking for.

Black will apply no spaces around ':' operators for 'simple' expresssions
, but will apply extra space around ':' operators for 'complex' expressions.
Black treats anything more than variable names as 'complex', but this isn't
noted in the Black documentation. Which leads to a few issues on the GitHub
issue tracker that all report inconsistent spacing around ':' operators.
Termux's Python environment doesn't provide sem_open, but fails with a
nested `ImportError` on import attempts:
ImportError: cannot import name 'SemLock' from '_multiprocessing'
This updates the existing handling for AWS Lambda to catch both
`OSError` and `ImportError`.
- Move black.py to src/black/__init__.py
- Have setuptools_scm make src/_black_version.py and exclude from git
- Move blackd.py to src/blackd/__init__.py
- Move blib2to3/ to src/
- Update `setup.py`
- Update unittests to pass
- Mostly path fixing + resolving
- Update CI
- pre-commit config
- appveyor + travis
Tested on my mac with python 3.7.5 via:
```
python3 -m venv /tmp/tb3
/tmp/tb3/bin/pip install --upgrade setuptools pip coverage pre-commit
/tmp/tb2/bin/pip install ~/repos/black/
cd ~/repos/black/
/tmp/tb2/bin/coverage run tests/test_black.py
/tmp/tb3/bin/pre-commit run -a
/tmp/tb3/bin/black --help
/tmp/tb3/bin/black ~/repos/ptr/ptr.py
```
* Adding documentation to the README for import errors in vim
I had the same issue as psf/black#1148 and have been searching for a
solution to this. I realized that you cannot fix it by change anything
in the code, but by re-compiling the C extensions of regex and
typed-ast. Installing this packages from the tarballs solves the
problem.

* Add Black compatible configs in docs ( #1366 & #1205)
When users of Black are starting a new project or are adding Black to their
existing projects, they will usually have to config their existing tools like
flake8 to be compatible with Black. Usually, these configs are the same across
different projects. Yet, there isn't any consolidated infomation on what configs
are compatible. Leaving users of Black to dig out any infomation they can find
in README.md.
* Fix a bad max-line-length value
* Clean up pylint's configs
* Add explanations for each configurations
Copying and pasting code without understanding it is a bad idea. This goes the same
for users copying and pasting configurations.
* Capitalize Pylint
* Link from the README
* Fix the isort configuration
I referenced the wrong source. I used a pesonal configuration, not a pure Black-
compatible configuration.
* Improve the config explanations
The explanation for the isort configuration was pretty bad. After having fixed the
configuration (see commit 01c55d1), improving the its explanation was necessary to
make it more user-friendly and understandable. Also added fenced code blocks of the
raw configuration options so the explanations make sense.
* Improve README wording slightly
* Add @hugovk, @JelleZijlstra + my suggestions

AWS Lambda and some other virtualized environment may not permit access
to /dev/shm on Linux and as such, trying to use ProcessPoolExecutor will
fail.
As using parallelism is only a 'nice to have' feature of black, if it fails
we gracefully fallback to a monoprocess implementation, which permits black
to finish normally.

The `venv` module relies on `sys._base_executable` to determine the
Python executable to run, but with recent versions of Vim, this is set
to the `vim` executable. A possible workaround is to just override it,
since the `black` plugin already overrides `sys.executable` (possibly
for similar reasons?) anyway.
* Re-indent the contents of docstrings when indentation changes
Keeping the contents of docstrings completely unchanged when
re-indenting (from 2-space intents to 4, for example) can cause
incorrect docstring indentation:
```
class MyClass:
"""Multiline
class docstring
"""
def method(self):
"""Multiline
method docstring
"""
pass
```
...becomes:
```
class MyClass:
"""Multiline
class docstring
"""
def method(self):
"""Multiline
method docstring
"""
pass
```
This uses the PEP 257 algorithm for determining docstring indentation,
and adjusts the contents of docstrings to match their new indentation
after `black` is applied.
A small normalization is necessary to `assert_equivalent` because the
trees are technically no longer precisely equivalent -- some constant
strings have changed. When comparing two ASTs, whitespace after
newlines within constant strings is thus folded into a single space.

* Extract the inner `_v` method to decrease complexity
This reduces the cyclomatic complexity to a level that makes flake8 happy.
* Blacken blib2to3's docstring which had an over-indent

This pull request's main intention is to wraps long strings (as requested by #182); however, it also provides better string handling in general and, in doing so, closes the following issues:
Closes#26Closes#182Closes#933Closes#1183Closes#1243
- This makes black wheels to be tagged as py3 default
- `python_requires=">=3.6"` ensures we are >= 3.6
Test:
```
python3 -m venv /tmp/build_black
/tmp/build_black/bin/pip install --upgrade pip setuptools wheel
/tmp/build_black/bin/python setup.py bdist_wheel
...
black-19.10b1.dev53+g81bf9bb.d20200508-py3-none-any.whl
```
Addresses #1385
Fixes#1360, where an invalid config file causes a return/exit code of 1. This
change means this case is caught earlier, treated like any other bad
parameters, and results in an exit code of 2.

* fix: Fixing the documentation of how to install the vim plugin
Solves the installation problem that currently exist because
the current master branch is not stable. See psf/black#1304 for
more information.
* fix: fixing incorrect path
`split("\n")` includes a final empty element `""` if the final line
ends with `\n` (as it should for POSIX-compliant text files), which
then became an extra `"\n"`.
`splitlines()` solves that, but there's a caveat, as it will split
on other types of line breaks too (like `\r`), which may not be
desired.
Fixes#526.
