Recommend B950 + 88 char limit instead of 80 (#2050)
[The section about line length][1] was contradictory.
On one side, it said:
> Black will try to respect that [line length limit]. However, sometimes it won't be able to without breaking other rules. In those rare cases, auto-formatted code will exceed your allotted limit.
So black doesn't guarantee that your code is formatted at 88 chars, even when configured with `--line-length=88` (default). Black uses this limit as a "hint" more than a "rule".
OTOH, it also said:
> If you're using Flake8, you can bump max-line-length to 88 and forget about it. Alternatively, use Bugbear's B950 warning instead of E501 and keep the max line length at 80 which you are probably already using.
But that's not true. You can't "forget about it" because Black sometimes won't respect the limit. Both E501 at 88 and B950 at 80 behave the same: linter error at 89+ length. So, if Black happens to decide that a line of code is better at 90 characters that some other fancy style, you land on a unlucky situation where both tools will fight.
So, AFAICS, the best way to align flake8 and black is to:
1. Use flake8-bugbear
2. Enable B950
3. Disable E501
4. Set `max-line-length = 88`
This way, we also tell flake8 that 88 limit is a "hint" and not a "rule". The real rule will be 88 + 10%. If black decides that a line fits better in 97 characters than in 88 + some formatting, _that_ probably means your code has a real problem.
To avoid further confusion, I change the official recommendation here.

Work-around for https://bugs.python.org/issue2142
The test has to slightly mess with its input data, because the utility
functions default to ensuring the test data has a final newline, which
defeats the point of the test.

Stability fixup: interaction between newlines and comments (#1975)
* Add test case to illustrate the issue
* Accept carriage returns as valid separators while enumerating comments
Without this acceptance, escaped multi-line statments that use carriage returns will not be counted into the 'ignored_lines' variable since the emitted line values will end with a CR and not an escape character. That leads to comments associated with the line being incorrectly labeled with the STANDALONE_COMMENT type, affecting comment placement and line space management.

Update prettier in pre-commit config (#1966)
With older versions of prettier, when the hook failed a bunch of
"[error] No parser could be inferred for file: {PATH}" error lines

passes for us by default. It made figuring out why the prettier hook
failed annoying.

Update example exclude to match only files in root (#1861)
* Update example exclude to match only files in root
The `exclude` section of the example `pyproject.toml` file didn't work
as expected. It claimed to exclude matched files only in the project
root, but it actually excluded matched files at any directory level
within the project. We can address this by prepending `^/` to the regex
to ensure that it only matches files in the project root.

Bump mypy to 0.780 in pre-commit config (#1887)
To avoid hitting a mypy bug causes pre-commit to always fail on CPython
3.9. Even though it's still an outdated version, the bug effectively
blocks development on CPython 3.9 so that's why this commit exists
instead of waiting for cooperlees to finish his bump to 0.790 PR.
Also this fixes primer to ensure it always raises CalledProcessError
with an int error code. I stole the patch from cooperlees's mypy bump
PR.
It's funny how mypy 0.790 is already asked for in our
Pipfile.lock file, but oh well mypy is probably more commonly run
through pre-commit than standalone I guess.
Oh and if you're curious why the bug doesn't up on CPython 3.8 or lower:
there was some subscription AST changes in CPython 3.9.

Automatically build and upload binaries on release (#1743)
This commit adds a new GitHub Actions workflow that builds self-contained
binaries / executables and uploads them as release assets to the triggering
release. Publishing a release, drafting one doesn't count, will trigger this
workflow.
I personally used GitHub Actions only because it's the CI/CD platform(?)
I am familiar with. Only Windows and Linux binaries are supported since
I don't have any systems running Mac OS.
For Linux, I had originally planned to use the manylinux2010 docker image
the PyPA provides for highly compatible wheel building, but unfortunately
it wasn't feasible due to GitHub Actions and PyInstaller incompatibilities.
As a stopgap the oldest versions of Linux and Windows are used although
Windows Server 2019 isn't that old nor is Ubuntu 16.04! I guess someone
(maybe me) could work out something else if compatibility is big problem.
A few things you should know about the workflow:
- You don't need to set the `GITHUB_TOKEN` secret as it is automatically
provided by GitHub.
- matrix.pathsep is used because PyInstaller configuration's format is OS
dependent for some reason ...
Also it's worth mentioning that Black once had Travis CI and AppVeyor
configuration that did the same thing as this commit. They were committed
in mid 2018 and worked (somewhat) well. Eventually we stopped using AppVeyor
and the refactor to packages broke the Travis CI config. This commit
replaces the still existing and broken Travis CI config wholesale.

Repair colorama wrapping on non-Windows platforms (#1670)
* Repair colorama wrapping on non-Windows platforms
The wrap_stream_for_windows() function calls
colorama.initialise.wrap_stream() function to apply colorama's magic to
wrapper to the output stream. Except this wrapper is only applied on
Windows platforms that need it, otherwise the original stream is
returned as-is.
The colorama wrapped stream lacks a detach() method, so a no-op lambda
was being assigned to the wrapped stream.
The problem is that the no-op lambda was being assigned unconditionally
whether or not colorama actually returns a wrapped stream, thus
replacing the original TextIOWrapper's detach() method. Replacing the
detach() method with a no-op lambda is the root cause of the problem
observed in #1664.
The solution is to only assign the no-op detach() method if the stream
lacks its own detach() method.

Fix empty line handling when formatting typing stubs (#1646)
Black used to erroneously remove all empty lines between non-function
code and decorators when formatting typing stubs. Now a single empty
line is enforced.
I chose for putting empty lines around decorated classes that have empty
bodies since removing empty lines around such classes would cause a
formatting issue that seems to be impossible to fix.
For example:
```
class A: ...
@some_decorator
class B: ...
class C: ...
class D: ...
@some_other_decorator
def foo(): -> None: ...
```
It is easy to enforce no empty lines between class A, B, and C.
Just return 0, 0 for a line that is a decorator and precedes an stub
class. Fortunately before this commit, empty lines after that class
would be removed already.
Now let's look at the empty line between class D and function foo. In
this case, there should be an empty line there since it's class code next
to function code. The problem is that when deciding to add X empty lines
before a decorator, you can't tell whether it's before a class or a
function. If the decorator is before a function, then an empty line
is needed, while no empty lines are needed when the decorator is
before a class.
So even though I personally prefer no empty lines around decorated
classes, I had to go the other way surrounding decorated classes with
empty lines.
