It appears sqlalchemy has recently reformatted their project with
Black 21.5b1.
Most of our dependencies have a lower bound and creating a test
environment with the oldest acceptable dependencies runs the full
Black test suite just fine. The only exception to this is aiohttp-cors.
It's unbounded and the oldest version 0.1.0 until 0.4.0 breaks the
test suite in such an old environment.
Failure with 0.1.0:

Commit history before merge:
* Replace references to master branch
* Update .flake8 to reference docs on RTD
We're moving away from GitHub as a documentation host to only RTD because
it's makes our lives easier creating good docs. I know this link is dead right now,
but it won't be once we release a new version with the documentation reorganization
changes (which should be soon!).
Co-authored-by: Richard Si <63936253+ichard26@users.noreply.github.com>
I know I know, this is the second reorganization of the docs. I'm not
saying the first one was bad or anything... but.. actually wait nah,
*it was bad*.
Anyway, welcome to probably my biggest commit. The main thing with this
reorganization was to introduce nesting to the documentation! Having
all of the docs be part of the main TOC was becoming too much. There
wasn't much room to expand either. Finally, the old setup required
a documentation generation step which was just annoying.
The goals of this reorganization was to:
1. Significantly restructure the docs to be discoverable and
understandable
2. Add room for further docs (like guides or contributing docs)
3. Get rid of the doc generation step (it was slow and frustrating)
4. Unblock other improvements and also just make contributing to the
docs easier
Another important change with this is that we are no longer using GitHub
as a documentation host. While GitHub does support Markdown based docs
actually pretty well, the lack of any features outside of GitHub Flavoured
Markdown is quite limiting. ReadTheDocs is just much better suited for
documentation. You can use reST, MyST, CommonMark, and all of their
great features like toctrees and admonitions.
Related to this change, we're adopting MyST as our flavour of Markdown.
MyST introduces neat syntax extensions to Markdown that pretty much
gives us the best of both worlds. The ease of use and simplicity of MD
and the flexibility and expressiveness of reST. Also recommonmark is
deprecated now. This switch was possible now we don't use GH as a docs
host. MyST docs have to be built to really be usable / pretty, so the MD
docs are going to look pretty bad on GH, but that's fine now!
Another thing that should be noted is that the README has been stripped
of most content since it was confusing. Users would read the README and
then think some feature or bug was fixed already and is available in a
release when in reality, they weren't. They were reading effectively
the latest docs without knowing.

FYI: CommonMark is a rationalized version of Markdown syntax

Commit history before merge:
* Switch to MyST-Parser + doc config cleanup
recommonmark is being deprecated in favour of MyST-Parser. This change
is welcomed, especially since MyST-Parser has syntax extensions for the
Commonmark standard. Effectively we get to use a language that's powerful
and expressive like ReST, but get the simplicity of Markdown.
The rest of this effort will be using some MyST features.
This reorganization efforts aims to remove as much duplication as possible.
The regeneration step once needed is gone, significantly simplifing our
Sphinx documentation configuration.
* Tell pipenv we replaced recommonmark for MyST-Parser
Also update `docs/requirements.txt`
* Delete all auto generated content
* Switch prettier for mdformat (plus a few plugins)
**FYI: THIS WAS EFFECTIVELY REVERTED, SEE THIRD TO LAST COMMIT**
prettier doesn't support MyST's syntax extensions which are going to be
used in this reorganization effort so we have to switch formatter.
Unfortanately mdformat's style is different from prettier's so time to
reformat the whole repo too.
We're excluding .github/ISSUE_TEMPLATE because I have no idea whether
its changes are safe, so let's play it safe.
* Fix the heading levels in CHANGES.md + a link
MyST-Parser / sphinx's linkcheck complains otherwise.
* Move reference docs into a docs/contributing dir
They're for contributors of Black anyway. Also added a note in the
summary document warning about the lack of attention the reference has
been dealing with.
* Rewrite and setup the new landing page + main TOC
- add some more detail about Black's beta status
- add licensing info
- add external links in the main TOC for GitHub, PyPI, and IRC
- prepare main TOC for new structure
* Break out AUTHORS into its own file
Not only was the AUTHORS list quite long, this makes it easy to include
it in the Sphinx docs with just a simple symlink.
* Add license to docs via a simple include
Yes the document is orphaned but it is linked to in the landing page
(docs/index.rst).
* Add "The Black Code Style" section
This mostly was a restructuring commit, there has been a few updates but
not many. The main goal was to split "current style" and "planned
changes to the style that haven't happened yet" to avoid confusion.
* Add "Getting Started" page
This is basically a quick start + even more. This commit is certainly
one of most creatively involved in this effort.
* Add "Usage and Configuration" section
This commit was as much restructuring as new content. Instead of being
in one giant file, usage and configuration documentation can expand
without bloating a single file.
* Add "Integrations" section
Just a restructuring commit ...
* Add "Guides" section
This is a promising area of documentation that could easily grow in the
future, let's prepare for that!
* Add "Contributing" section
This is also another area that I expect to see significant growth in.
Contributors to Black could definitely do with some more specific docs
that clears up certain parts of our slightly confusing project (it's
only confusing because we're getting big and old!).
* Rewrite CONTRIBUTING.md to just point to RTD
* Rewrite README.md to delegate most info to RTD
* Address feedback + a lot of corrections and edits
I know I said I wanted to do these after landing this but given there's
going to be no time between this being merged and a release getting
pushed, I want these changes to make it in.
- drop the number flag for mdformat - to reduce diffs, see also:
https://mdformat.readthedocs.io/en/stable/users/style.html#ordered-lists
- the GH issue templates should be safe by mdformat, so get rid of the
exclude
- clarify our configuration position - i.e. stop claiming we don't have
many options, instead say we want as little formatting knobs as
possible
- lots and lots of punctuation, spelling, and grammar corrections (thanks
Jelle!)
- use RTD as the source for the CHANGELOG too
- visual style cleanups
- add docs about our .gitignore behaviour
- expand GHA Action docs
- clarify we want the PR number in the CHANGELOG entry
- claify Black's behaviour for with statements post Python 3.9
- italicize a bunch of "Black"s
Thank you goes to Jelle, Taneli (hukkinj1 on GH), Felix
(felix-hilden on GH), and Wouter (wbolster on GH) for the feedback!
* Merge remote-tracking branch 'upstream/master' into reorganize-docs-v2
merge conflicts suck, although these ones weren't too bad.
* Add changelog entry + fix merge conflict resolution error
I consider this important enough to be worthy of a changelog entry :)
* Merge branch 'master' into reorganize-docs-v2
Co-authored-by: Łukasz Langa <lukasz@langa.pl>
* Actually let's continue using prettier
Prettier works fine for all of the default MyST syntax so let's not
rock the boat as much. Dropping the mdformat commit was merge-conflict
filled so here's additional commit instead.
* Address Cooper's, Taneli's, and Jelle's feedback
Lots of wording improvements by Cooper. Taneli suggested to disable the
enabled by default MyST syntax not supported by Prettier and I agreed.
And Jelle found one more spelling error!
* More minor fixes
* Move string-related utility to functions to strings.py, const.py
* Move Leaf/Node-related functionality to nodes.py
* Move comment-related functions to comments.py
* Move caching to cache.py and Mode/TargetVersion/Feature to mode.py
* Move some leftover functions to nodes.py, comments.py, strings.py
* Add missing files to source list for test runs
* Move line-related functionality into lines.py, brackets into brackets.py
* Move transformers to trans.py
* Move file handling, output, parsing, concurrency, debug, and report
* Move two more functions to nodes.py
* Add CHANGES
* Add numeric.py
* Add linegen.py
* More docstrings
* Include new files in tests

Closes#2164.
Changes behavior of how .gitignore is handled. With this change, the rules in .gitignore are only used as a fallback if no exclusion rule is explicitly passed on the command line or in pyproject.toml. Previously they were used regardless if explicit exclusion rules were specified, preventing any overriding of .gitignore rules.
Those that depend only on .gitignore for their exclusion rules will not be affected. Those that use both .gitignore and exclude will find that exclude will act more like actually specifying exclude and not just another extra-excludes. If the previous behavior was desired, they should move their rules from exclude to extra-excludes.
Previously the RELAXED_DECORATOR detection would be falsely True on that
example. The problem was that an argument-less parentheses pair didn't
pass the `is_simple_decorator_trailer` check even it should. OTOH a
parentheses pair containing an argument or more passed as expected.
- Allow runs with no code diff output
- This is handy for reducing output to see which file is erroring
Test:
- Edit config for 'channels' to expect no changes and run with `--no-diff` and see no diff output
Black would previously strip the parenthesis away from statements like this these ones:
assert (spam := 12 + 1)
return (cheese := 1 - 12)
Which happens to be invalid code. Now before making the parenthesis invisible, Black
checks if the assignment expression's parent is an assert stamtment, aborting if True.
Raise, yield, and await are already handled fine.
I added a bunch of test cases from the PEP defining asssignment expressions (PEP 572).
Optional trailing commas put by Black become magic trailing commas on another
pass of the tool. Since they are influencing formatting around optional
parentheses, on rare occasions the tool changes its mind in terms of putting
parentheses or not.
Ideally this would never be the case but sadly the decision to put optional
parentheses or not (which looks at pre-existing "magic" trailing commas) is
happening around the same time as the decision to put an optional trailing
comma. Untangling the two proved to be impractically difficult.
This shameful workaround uses the fact that the formatting instability
introduced by magic trailing commas is deterministic: if the optional trailing
comma becoming a pre-existing "magic" trailing comma changes formatting, the
second pass becomes stable since there is no variable factor anymore on pass 3,
4, and so on.
For most files, this will introduce no performance penalty since `--safe` is
already re-formatting everything twice to ensure formatting stability. We're
using this result and if all's good, the behavior is equivalent. If there is
a difference, we treat the second result as the binding one, and check its
sanity again.
Fixes#1738. Fixes#1812.
Previously, Black removed leading and trailing spaces in multiline docstrings but failed to remove them from one-line docstrings.
The PR author added the changelog entry for their `extend-exclude` addition
in `docs/change_log.md` which is understandable but incorrect as it will be
overwritten since it's autogenerated from the readme.
Fixes: #1662
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.

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.

- Anders told me that I could get the release asset upload URL directly
from the github.event.release payload. I originally planned to use
bruceadams/get-release to get such URL.
* 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.
Repairs #1664
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.

* Fix incorrect space before colon in if/while stmts
Previously Black would format this code
```
if (foo := True):
print(foo)
```
as
```
if (foo := True) :
print(foo)
```
adding an incorrect space after the RPAR. Buggy code in the
normalize_invisible_parens function caused the colon to be wrapped in
invisible parentheses. The LPAR of that pair was then prefixed with a
single space at the request of the whitespace function.
This commit fixes the accidental skipping of a pre-condition check
which must return True before parenthesis normalization of a specific
child Leaf or Node can happen. The pre-condition check being skipped
was why the colon was wrapped in invisible parentheses.
* Add an entry in CHANGES.md
The quotes of multiline docstrings are now only normalized when string
normalization is off, instead of the string normalization setting being
ignored and the quotes being *always* normalized.
I had to make a new test case and data file since the current pair for
docstrings only worked when there is no formatting difference between the
formatting results with string normalization on and off. I needed to add
tests for when there *are* differences between the two. So I split
test_docstring's test code when string normalization is disabled into a
new test case along with a new data file.
