Ever since --force-exclude was added, --exclude started to touch files
that were given to Black through the CLI too. This is not documented
behaviour and neither expected as --exclude and --force-exclude now
behave the same!
Before this commit, get_sources() when encountering a file that was passed
explicitly through the CLI would pass a single Path object list to
gen_python_files(). This causes bad behaviour since that function
doesn't treat the exclude and force_exclude regexes differently. Which
is fine for recursively found files, but *not* for files given through
the CLI.
Now when get_sources() iterates through srcs and encounters
a file, it checks if the force_exclude regex matches, if not, then the
file will be added to the computed sources set.
A new function had to be created since before you can do regex matching,
the path must be normalized. The full process of normalizing the path is
somewhat long as there is special error handling. I didn't want to
duplicate this logic in get_sources() and gen_python_files() so that's
why there is a new helper function.
Partial fix for #1581
This assertion produces behavior quadratic in the number of leaves in a line, which is making Black extremely slow on files with very long expressions. On my benchmark file this change makes Black 10x faster.
Isort 5 introduced profiles and ensure_newline_before_comments options. Either needs to be added to work correctly with black.

Stable tag wasn't available and crashed when attempting to set initial
pre-commit. Also the python version needs to be installed so it would
be better to use the generic "python3" command.
Black wouldn't be where it is without the countless outside contributions.
So thank you y'all and we will share our appreciation by listing your names
(and emails) in the README.md :D
* Bump toml from 0.10.0 to 0.10.1 to fix a bug
* Add tests for TOML parsing and reading
* Fix configuration bug affecting vim plugin
The vim plugin directly calls parse_pyproject and skips the Click processing
, but parse_pyproject assumed that it would only be used before Click processing
and therefore made the config values click friendly. This moves the "make the values
click friendly processing" into read_pyproject_toml which is only called by a Click
callback.
* Please mypy and flake8
With this config:
```toml
[tool.black]
line-length = 79
```
In neovim, this is loaded as a string which later causes an exception to
be thrown. This makes sure the value is always cast to an int
As discussed in #1441, Python 3.9's new parser will not parse
`(*starred)` even using `compile()` with the `PyCF_ONLY_AST`
flag (as `ast.parse()` does), it raises a `SyntaxError`. This
breaks the four tests that use this file with Python 3.9.
Upstream does not consider this to be a bug - see
https://bugs.python.org/issue40848#msg370643 - so we must
adjust the expression. As suggested by @JelleZijlstra, this just
adds a comma, which makes the new parser happy with it (the old
parser is fine with this form also).

* Implement a re-usable GitHub Action
Implement a GitHub action that can be reused across projects that want
to run black as part of their CI workflows.
* Fix typo in README.md

* Use latest Python 3

* Convert config values to string
We need to convert all configuration values from the pyproject.toml
file because Click already does value processing and conversion and
it only expects the exact Python type or string. Click doesn't like
the integer 1 as a boolean for example. This also means other
unsupported types like datetime.time will be rejected by Click as
a unvalid value instead of throwing an exception.
We only skip converting objects that are an instance of
collections.abc.Iterable because it's almost impossible to get back
the original iterable of a stringified iterable.
* Move where the conversion happens
Instead of converting the values in the merged 'default_map', I should
convert the values that were read from the 'pyproject.toml' file.
* Change collections.abc.Iterable to (list, dict)
I also moved where the conversion happens... again. I am rather indecisive
if you haven't noticed. It should be better as it takes place in the
parse_pyproject_toml logic where configuration modification already takes
place.
Actually when this PR was first created I had the conversion happen in that
return statement, but the target_version check was complaining about it being
a string. So I moved the conversion after that check, but then Click didn't
like the stringifed list, which led me to check whether the value was an
instance of an Iterable before turning it into a string. And... I forgot that
type checking before conversion would allow it to work before the
target_version check anyway.
* Update CONTRIBUTION with pre-commit + black-primer instructions
- Inform people how to run primer and alter it's config
- Link to main documentation
* Apply suggestions from code review

* 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
Co-Authored-By: Hugo van Kemenade <hugovk@users.noreply.github.com>
* 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
- Leave logic to still allow for formatting changes to be ignored
- Now just capture the output of any other error that has a > 1 returncode
- Raise on anything else
Test: Add unit test to exercise this new logic
* Add all listed by projects into primer.json + Enable on CI Runs
- Change workers default to 2 as black uses system CPU count
- Increase timeout to 5 mins for subprocess black runs
- Takes about 120s for 13 (3 disabled) projects on my 2018 Macbook Pro
- I was not removing directories tho ...
Will open an issue to investigate the failing projects and make this run cleaner.
- Once we get more stable we can expect more repos to be black formatted
Run it:
- `black-primer -k -w /tmp/primer_large_test --debug --rebase`
