`black.strings.get_string_prefix` used to lowercase the extracted
prefix before returning it. This is wrong because 1) it ignores the
fact we should leave R prefixes alone because of MagicPython, and 2)
there is dedicated prefix casing handling code that fixes issue 1.
`.lower` is too naive.
This was originally fixed in 20.8b0, but was reintroduced since 21.4b0.
I also added proper prefix normalization for docstrings by using the
`black.strings.normalize_string_prefix` helper.
Some more test strings were added to make sure strings with capitalized
prefixes aren't treated differently (actually happened with my original
patch, Jelle had to point it out to me).
Not sure the fix is right. Here is what I found: issue is connected
with line
first.prefix = prefix[comment.consumed :]
in `comments.py`. `first.prefix` is a prefix of the line, that ends
with `# fmt: skip`, but `comment.consumed` is the length of the
`" # fmt: skip"` string. If prefix length is greater than 14,
`first.prefix` will grow every time we apply formatting.
Fixes#2254
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

PR #2286 did not fix the edge-cases (e.g. when the string is just long
enough to cause a line to be 89 characters long). This PR corrects that
mistake.
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
* Add optional uvloop import
- If we find `uvloop` in the env for black, blackd or black-primer lets try and use it
- Add a uvloop extra install
Fixes#2257
Test:
- Add ci job to install black[uvloop] and run a primer run with uvloop
- Only with latest python (3.9)
- Will be handy to compare runtimes as a very unoffical benchmark
* Remove tox install
* Add to CHANGES/news
Resolves#2168 by disabling the insertion of a " " when the docstring is entirely empty.
Note that this PR is focussed only on the case of empty docstrings. In particular this does not make any changes to the behaviour that a " " is inserted if a non-empty docstring begins with the quoting character. That is, black still prefers:
""" "something" """
to:
""""something" """
and that:
""""Something""""
is not a legal docstring.
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.

* Solved Problem with non-alphabetical .gitignore files
When .gitignore file in the user's project directory contained non-alphabetical
characters(Japanese, Korean, Chinese, etc), Nothing works and printed this
weird message in the console('cp949' is the encoding for Korean characters
in this case). It even blocks VSCode's formatting from working. This commit
solves the problem.

It appears sqlalchemy has recently reformatted their project with
Black 21.5b1.

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.

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
(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).
