Reorganize docs v2 (GH-2174)
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.
* 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:

many options, instead say we want as little formatting knobs as

Speed up tests even more (#2205)
There's three optimizations in this commit:
1. Don't check if Black's output is stable or equivalant if no changes
were made in the first place. It's not like passing the same code
(for both source and actual) through black.assert_equivalent or
black.assert_stable is useful. It's not a big deal for the smaller
tests, but it eats a lot of time in tests/test_format.py since
its test cases are big. This is also closer to how Black works IRL.
2. Use a smaller file for `test_root_logger_not_used_directly` since
the logging it's checking happens during blib2to3's startup so the
file doesn't really matter.
3. If we're checking a file is formatting (i.e. test_source_is_formatted)
don't run Black over it again with `black.format_file_in_place`.
`tests/test_format.py::TestSimpleFormat.check_file` is good enough.

Drop Travis CI and migrate Coveralls (#2186)

- 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

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.

parentheses pair containing an argument or more passed as expected.

primer: Renable pandas (#2185)

- Update django reason to name the file causing error

Add automatic version tagging to Docker CI Pushes (#2132)
* Add automatic version tagging to Docker Uploads
- If the git comment has a tag, set that on the docker images pushed
- If we don't have a tag, we just set `latest_non_release`

Stop stripping parens in even more illegal spots (#2148)
We're only fixing them so fuzzers don't yell at us when we break "valid"
code. I mean "valid" because some of the examples aren't even accepted by
Python.

Don't strip parens in assert / return with assign expr (#2143)
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).

Docker CI: Add missed Checkout step (#2128)

Work around stability errors due to optional trailing commas (#2126)
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.

Push contributors to use Next PR Number (#2080)
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.
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.
