written caused their shell to try to do command expansion.

Now PRs will run two diff-shades jobs, "preview-changes" which formats
all projects with preview=True, and "assert-no-changes" which formats
all projects with preview=False. The latter also fails if any changes
were made.
Pushes to main will only run "preview-changes"
Also the workflow_dispatch feature was dropped since it was
complicating everything for little gain.
- use `Black` directly: the commands an autocommand runs are Ex commands, so no
execute or colon is necessary.
- use an `augroup` (best practice) to prevent duplicate autocommands from
hindering performance.
I did this manually for the last few releases and I think it's going to be
helpful in the future too. Unfortunately this adds a little more work during
the release (sorry @cooperlees).
This change will also improve the merge conflict situation a bit, because
changes to different sections won't merge conflict.
For the last release, the sections were in a kind of random order. In the
template I put highlights and "Style" first because they're most important
to users, and alphabetized the rest.
At the moment, it's just a source of spurious CI failures and busywork
updating the configuration file.
Unlike diff-shades, it is run across many different platforms and
Python versions, but that doesn't seem essential. We already run unit
tests across platforms and versions.
I chose to leave the code around for now in case somebody is using it,
but CI will no longer run it.
Since power operators almost always have the highest binding power in expressions, it's often more readable to hug it with its operands. The main exception to this is when its operands are non-trivial in which case the power operator will not hug, the rule for this is the following:
> For power ops, an operand is considered "simple" if it's only a NAME, numeric CONSTANT, or attribute access (chained attribute access is allowed), with or without a preceding unary operator.
Fixes GH-538.
Closes GH-2095.

Closes#2360: I'd like to make passing SRC or `--code` mandatory and the arguments mutually exclusive. This will change our (partially already broken) promises of CLI behavior, but I'll comment below.
- State we're now stable and that we'll uphold our formatting changes as per policy
- Link to The Black Style doc.

Fixes#2506
``XDG_CACHE_HOME`` does not work on Windows. To allow for users to set a custom cache directory on all systems I added a new environment variable ``BLACK_CACHE_DIR`` to set the cache directory. The default remains the same so users will only notice a change if that environment variable is set.
The specific use case I have for this is I need to run black on in different processes at the same time. There is a race condition with the cache pickle file that made this rather difficult. A custom cache directory will remove the race condition.
I created ``get_cache_dir`` function in order to test the logic. This is only used to set the ``CACHE_DIR`` constant.
- Add Furo dependency to docs/requirements.txt
- Drop a fair bit of theme configuration
- Fix the toctree declarations in index.rst
- Move stuff around as Furo isn't 100% compatible with Alabaster
Furo was chosen as it provides excellent mobile support, user
controllable light/dark theming, and is overall easier to read
*blib2to3's support was left untouched because: 1) I don't want to touch
parsing machinery, and 2) it'll allow us to provide a more useful error
message if someone does try to format Python 2 code.
We were no longer using it since GH-2644 and GH-2654. This should hopefully
make using Black easier to use as there's one less compiled dependency.
The core team also doesn't have to deal with the surprisingly frequent fires
the regex packaging setup goes through.

Fixes https://github.com/psf/black/issues/2627 , a non-Python cell magic such as `%%writeline` can legitimately contain "incorrect" indentation, however this causes `tokenize-rt` to return an error. To avoid this, `validate_cell` should early detect cell magics (just like it detects `TransformerManager` transformations).
Test added too, in the shape of a "badly indented" `%%writefile` within `test_non_python_magics`.

* Update CHANGES.md for 21.10b0 release
* Update version in docs/usage_and_configuration/the_basics.md
* Also update docs/integrations/source_version_control.md ...
* Prepare for Python 2 depreciation
- Use BlackRunner and .stdout in command line test
So the next commit won't break this test. This is in its own commit so
we can just revert the depreciation commit when dropping Python 2
support completely.
* Deprecate Python 2 formatting support
Fixes#2394. Eventually fixes#517.
This is essentially @pradyunsg's suggestion from #2394. I suggest that at the
same time we start the formal stability policy, we take a few other disruptive steps
and drop Python 2 and the "b" marker.

While this development environment / requirements situation is a mess,
let's at least make it consistent. We're effectively supporting two
modes of development in this project, 1) tox based dev commands
(e.g. `tox -e fuzz`) that are dead simple to use, and 2) manual dev
commands (e.g. `pytest -n auto`) that give more control and are usually
faster.
Right now the Pipfile.lock based development environment is incomplete
missing the test requirements specified in ./test_requirements.txt.
This is annoying since manual test commands (e.g. `pytest -k fmtonoff`)
fail. Let's fix this by making Pipfile.lock basically a
"everything you need" requirements file (fuzzing not included since
running it locally is not something common).
Oh and let's bump some documentation deps (and bring some requirements
across .pre-commit-config.yaml, Pipfile, and docs/requirement.txt in
alignment again). Don't worry, I tested these changes so they should
be fine (hopefully!).
To summarise, based on what was discussed in that issue:
due to not being able to parse automagics (e.g. pip install black)
without a running IPython kernel, cells with syntax which is parseable
by neither ast.parse nor IPython will be skipped cells with multiline
magics will be skipped trailing semicolons will be preserved, as they
are often put there intentionally in Jupyter Notebooks to suppress
unnecessary output

This commit adds a short section discussing the non-processing of docstrings
besides spacing improvements, mentions comment moving and links to the
AST equivalence discussion. I also added a simple spacing test for good
measure.

* Mention comment non-processing in documentation, add spacing test
* Mention special cases for comment spacing
* Add all special cases, improve wording
Closes#1246: This PR adds a new option (and automatically a toml entry, hooray for existing configuration management 🎉) to require a specific version of Black to be running.
For example: `black --required-version 20.8b -c "format = 'this'"`
Execution fails straight away if it doesn't match `__version__`.
Commit history before merge:
* Add black_version to github action
* Merge upstream/main into this branch
* Add version support for the Black action pt.2
Since we're moving to a composite based action, quite a few changes
were made. 1) Support was added for all OSes (Windows was painful).
2) Isolation from the rest of the workflow had to be done manually
with a virtual environment.
Other noteworthy changes:
- Rewrote basically all of the logic and put it in a Python script
for easy testing (not doing it here tho cause I'm lazy and I can't
think of a reasonable way of testing it).
- Renamed `black_version` to `version` to better fit the existing
input naming scheme.
- Added support for log groups, this makes our action's output a
bit more fancy (I may or may have not added some debug output too).
* Add more to and sorta rewrite the Action's docs
Reflect compatability and gotchas.
* Add CHANGELOG entry
* Merge main into this branch
* Remove debug; address typos; clean up action.yml

There's some weird interaction between Click and
sphinxcontrib-programoutput on Windows that leads to an encoding error
during the printing of black-primer's help text.
Also symlinks aren't well supported on Windows so let's just use
includes which actually work because we now use MyST :D
This commit creates a Frequently Asked Questions document for our users
to read. Hopefully they actually read it too. Items included are:
Black's non-API, AST safety, style stability, file discovery, Flake8
disagreements and Python 2 support. Hopefully I've got the answers
down in general.
Commit history before merge:

The isort configuration currently in the Black code style document is
duplicated in Using Black with other tools document. I think it would
be better to consolidate information and simply link to the tool guide,
mentioning the easy profile in the original document.
I changed the link from isort PyPI page to Black's docs on isort
because for users it could be better to see the Black docs on why that
configuration is necessary and what isort is from Black's perspective.

The original changes in Pipfile.lock are whitespace only. The changes
turned the JSON's file indentation from 4 to 2. Effectively this
happened: `json.dumps(json.loads(old_pipfile_lock), indent=2) + "\n"`.
Just using main's Pipfile.lock instead of undoing the changes because
1) I don't know how to do that easily and quickly, and 2) there's a
merge conflict.

So these won't go out of date. This does mean the environment has be
setup a bit more carefully so the right version of the tool is used,
but thankfully the build environment is rebuilt on change on RTD anyway.
Also since the HTML docs are known to build fine, let's provide
downloadable HTMLzips of our docs.
This change needs RTD and GH to install Black with the [d] extra so
blackd's help can generated. While editing RTD's config file, let's
migrate the file to a non-deprecated filename.
Also I missed adding AUTHORS.md to the files key in the doc GHA config.
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.
See also: https://github.com/psf/black/issues/1759
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

* 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

Travis CI for Open Source is shutting down in a few weeks so the queue
for jobs is insane due to lower resources. I'm 99.99% sure we don't need
it as our Test, Lint, Docs, Upload / Package, Primer, and Fuzz workflows
are all on GitHub Actions. So even though we *can* migrate to the .com
version with its 1000 free Linux minutes(?), I don't think we need to.
more information here:
- https://blog.travis-ci.com/oss-announcement
- https://blog.travis-ci.com/2020-11-02-travis-ci-new-billing
- https://docs.travis-ci.com/user/migrate/open-source-repository-migration
This commit does the following:
- delete the Travis CI configuration
- add to the GHA test workflows so coverage continues to be recorded
- tweaked coverage configuration so this wouldn't break
- remove any references to Travis CI in the docs (i.e. readme + sphinx
docs)
Regarding the Travis CI to GitHub Actions Coveralls transition, the
official action doesn't support the coverage files produced by coverage.py
unfornately. Also no, I don't really know what I am doing so don't @ me
if this breaks :p (well you can, but don't expect me to be THAT useful).
The Coveralls setup has two downfalls AFAIK:
- Only Linux runs are used because AndreMiras/coveralls-python-action
only supports Linux. Although this isn't a big issue since the Travis
Coveralls configuration only used Linux data too.
- Pull requests from an internal branch (i.e. one on psf/black) will be
marked as a push coverage build by Coveralls since our anti-duplicate-
workflows system runs under the push even for such cases.
This is a tool of my own making. Right now our requirement to have the
PR number in the changelog entry is pretty painful / annoying since
the contributor either has to guess or add the # retroactively after
the PR creation. This tool should make it way less painful by making
it simple to get your PR number beforehand.
* Added support for top-level user configuration
At the user level, a TOML config can be specified in the following locations:
* Windows: ~\.black
* Unix-like: $XDG_CONFIG_HOME/black (~/.config/black fallback)
Instead of changing env vars for the entire black-primer process, they
are now changed only for the black subprocess, using a tmpdir.
[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.

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.
* Upgrade docs to Sphinx 3+
* Fix all the warnings...
- Fixed bad docstrings
- Fixed bad fenced code blocks in documentation
- Blocklisted some sections from being generated from the README
- Added missing documentation to index.rst
- Fixed an invalid autofunction directive in reference/reference_functions.rst
- Pin another documentation dependency
* Add documentation build test
Isort 5 introduced profiles and ensure_newline_before_comments options. Either needs to be added to work correctly with black.

* Split code style and components documentation
Splits 'the_black_code_style', 'pragmatism', 'blackd',and 'black_primer'
into their own files. The exception being 'the_black_code_style' and
'pragmatism'. They have been merged into one 'the_black_code_style_and_pragmatism'
file.
These changes are being made because the README is becoming very long. And
a README isn't great if it dissuades its reader because of its length.
* Update the doc generation logic and configuration
With the moving of several sections in the README and the renaming of a
few files, 'conf.py' needs to be able to support custom sections.
This commit introduces DocSection which can be used to specify custom
sections of documentation. The information stored in DocSection will be
used by the process_sections function to read, process, and write the section
to CURRENT_DIR.
A large change has been made to the how the docs are prepared to be built.
Instead of just generating the files needed by reading the README, this
has a full chain of operations so custom sections are supported. First,
it reads the README and spits out a list of DocSection objects representing
the sections to be generated by process_sections. This is done since most
of the docs still live in README. Then along with the defined custom_sections
, the process_sections will be begin to process the DocSection objects.
It reads the information it needs to generate the section. Then fetches
the section's contents, calls processors required by the section to process
the section's contents, and finally writes the section to CURRENT_DIR.
This large change is so processing of the documentation can be done just
for the versions hosted on ReadTheDocs.org. An example processor using this
feature is a 'replace_links' processor. It will replace documentation
links that point to the docs hosted on GitHub with links that point to the
version hosted on ReadTheDocs.org. (I won't be coding that ATM)
This also means that files will be overwritten or created once the docs
have been built. It is annoying, since you have to 'git reset --hard'
and 'git clean -f -d' after each build, but there's nothing better. The old
system had the same side effects, so yeah :(
* Update filenames and delete unnecessary files
Update the filenames since 'the_black_code_style' and 'pragmatism' were
merged and 'contributing' was deleted in favor of 'contributing_to_black'.
All symlinks were deleted since their home (_build/generated) is no longer
used.
* Fix broken links and a few redirections
* Merge master into refactor_docs (manually done)
* Add my and most of @hugovk suggestions

* Add logging and improve configurability
Just some cleaning up up of the DocSection dataclass and added logging
support so you know what's going on.
* Rename a section and please the grammar gods of Black
Thanks @hugovk for the suggestion!
* Fix Markdown comments
* Add myself as an author :P
Seems like the right time.

* Make the sidebar navigation scrollable
This is necessary since we have so many documentation sections that even
on a desktop screen, the navigation can sometimes be clipped. The only
annoyance is that on Firefox, the scrollbar can't be hidden :(
* allow the docs to build
* Add `black-primer` docs
- Document the idea, CLI args, config and a example run for `black-primer` in README.md
- Add to docs/index.rst
* Add @hugovk suggestions - Thanks.
* 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

* Remove reference to format_int_string in docs
The function got dropped in 250ba7f04b.
* Remove reference to is_python36 in docs
The function got removed in 36d3c516d3.
* add test for special unicode symbol which usual re can not process correctly
add regex lib which supports unicode 12.1.0 standard
replace re usage in project in favor to regex
* #455 fix dependency
The default behaviour is that now all lines break *before* delimiters,
instead of afterwards. The special cases for this are commas and
behaviour around args.
