This utility reformats and checks Python source code files. However, when run in a Git repository, it compares an old revision of the source tree to a newer revision (or the working tree). It then only applies reformatting in regions which have changed in the Git working tree between the two revisions.
The reformatters supported are:
NOTE: Baseline linting support has been moved to the Graylint_ package.

New in version 1.4.0: Darker can be used in plain directories, not only Git repositories.
.. |you-can-help| image:: https://img.shields.io/badge/-You%20can%20help-green?style=for-the-badge :alt: You can help .. |support| image:: https://img.shields.io/badge/-Support-green?style=for-the-badge :alt: Support .. _#151: https://github.com/akaihola/darker/issues/151 .. _community support channel: https://github.com/akaihola/darker/discussions
You want to start unifying code style in your project using Black_. Maybe you also like to standardize on how to order your imports, or do static type checking or other static analysis for your code.
However, instead of formatting the whole code base in one giant commit, you'd like to only change formatting when you're touching the code for other reasons.
This can also be useful when contributing to upstream codebases that are not under your complete control.
Partial formatting is not supported by Black_ itself,
for various good reasons, and so far there hasn't been a plan to implemented it either
(134
, 142
, 245
, 370
, 511
, 830
).
However, in September 2021 Black developers started to hint towards adding this feature
after all (1352
__). This might at least simplify Darker's algorithm substantially.
__ https://github.com/psf/black/issues/134 __ https://github.com/psf/black/issues/142 __ https://github.com/psf/black/issues/245 __ https://github.com/psf/black/issues/370 __ https://github.com/psf/black/issues/511 __ https://github.com/psf/black/issues/830 __ https://github.com/psf/black/issues/1352
But for the time being, this is where darker
enters the stage.
This tool is for those who want to do partial formatting right now.
Note that this tool is meant for special situations when dealing with existing code bases. You should just use Black_ and isort_ as is when starting a project from scratch.
You may also want to still consider whether reformatting the whole code base in one
commit would make sense in your particular case. You can ignore a reformatting commit
in git blame
using the blame.ignoreRevsFile
_ config option or --ignore-rev
on
the command line. For a deeper dive into this topic, see Avoiding ruining git blame
_
in Black documentation, or the article
Why does Black insist on reformatting my entire project?
_ from Łukasz Langa
_
(@ambv
_, the creator of Black). Here's an excerpt:
"When you make this single reformatting commit, everything that comes after is
**semantic changes** so your commit history is clean in the sense that it actually
shows what changed in terms of meaning, not style. There are tools like darker that
allow you to only reformat lines that were touched since the last commit. However,
by doing that you forever expose yourself to commits that are a mix of semantic
changes with stylistic changes, making it much harder to see what changed."

To install or upgrade, use::
pip install --upgrade darker~=2.1.1
Or, if you're using Conda_ for package management::
conda install -c conda-forge darker~=2.1.1 isort conda update -c conda-forge darker
..
**Note:** It is recommended to use the '``~=``' "`compatible release`_" version
specifier for Darker. See `Guarding against Black compatibility breakage`_ for more
information.
The darker <myfile.py>
or darker <directory>
command
reads the original file(s),
formats them using Black_,
combines original and formatted regions based on edits,
and writes back over the original file(s).
Alternatively, you can invoke the module directly through the python
executable,
which may be preferable depending on your setup.
Use python -m darker
instead of darker
in that case.
By default, darker
just runs Black_ to reformat the code.
You can enable additional features with command line options:
-i
/ --isort
: Reorder imports using isort_. Note that isort_ must be-f
/ --flynt
: Also convert string formatting to use f-strings using theflynt
packageNew in version 1.1.0: The -L
/ --lint
option.
New in version 1.2.2: Package available in conda-forge_.
New in version 1.7.0: The -f
/ --flynt
option
New in version 3.0.0: Removed the -L
/ --lint
functionality and moved it into
the Graylint_ package.
.. _Conda: https://conda.io/ .. _conda-forge: https://conda-forge.org/
This example walks you through a minimal practical use case for Darker.
First, create an empty Git repository:
.. code-block:: shell
$ mkdir /tmp/test $ cd /tmp/test $ git init Initialized empty Git repository in /tmp/test/.git/
In the root of that directory, create the ill-formatted Python file our_file.py
:
.. code-block:: python
if True: print('hi') print() if False: print('there')
Commit that file:
.. code-block:: shell
$ git add our_file.py $ git commit -m "Initial commit" [master (root-commit) a0c7c32] Initial commit 1 file changed, 3 insertions(+) create mode 100644 our_file.py
Now modify the first line in that file:
.. code-block:: python
if True: print('CHANGED TEXT') print() if False: print('there')
You can ask Darker to show the diff for minimal reformatting which makes edited lines conform to Black rules:
.. code-block:: diff
$ darker --diff our_file.py --- our_file.py +++ our_file.py @@ -1,3 +1,4 @@ -if True: print('CHANGED TEXT') +if True:
Alternatively, Darker can output the full reformatted file (works only when a single Python file is provided on the command line):
.. code-block:: shell
$ darker --stdout our_file.py
.. code-block:: python
if True: print("CHANGED TEXT") print() if False: print('there')
If you omit the --diff
and --stdout
options,
Darker replaces the files listed on the command line
with partially reformatted ones as shown above:
.. code-block:: shell
$ darker our_file.py
Now the contents of our_file.py
will have changed.
Note that the original print()
and if False: ...
lines have not been reformatted
since they had not been edited!
.. code-block:: python
if True: print("CHANGED TEXT") print() if False: print('there')
You can also ask Darker to reformat edited lines in all Python files in the repository:
.. code-block:: shell
$ darker .
Or, if you want to compare to another branch (or, in fact, any commit) instead of the last commit:
.. code-block:: shell
$ darker --revision master .
darker
, Black_, isort_ and flynt_ behaviordarker
invokes Black_ and isort_ internals directly instead of running their
binaries, so it needs to read and pass configuration options to them explicitly.
Project-specific default options for darker
itself, Black_ and isort_ are read from
the project's pyproject.toml
file in the repository root. isort_ does also look for
a few other places for configuration.
flynt_ (option -f
/ --flynt
) is also invoked as a subprocess, but passing
command line options to it is currently not supported. Configuration files need to be
used instead.
Darker does honor exclusion options in Black configuration files when recursing directories, but the exclusions are only applied to Black reformatting. Isort is still run on excluded files. Also, individual files explicitly listed on the command line are still reformatted even if they match exclusion patterns.
For more details, see:
Black documentation about pyproject.toml
_isort documentation about config files
_public GitHub repositories which install and run Darker
_flynt documentation about configuration files
_The following command line arguments
_ can also be used to modify the defaults:
-r REV, --revision REV
Revisions to compare. The default is HEAD..:WORKTREE:
which compares the
latest commit to the working tree. Tags, branch names, commit hashes, and other
expressions like HEAD~5
work here. Also a range like main...HEAD
or
main...
can be used to compare the best common ancestor. With the magic value
:PRE-COMMIT:
, Darker works in pre-commit compatible mode. Darker expects the
revision range from the PRE_COMMIT_FROM_REF
and PRE_COMMIT_TO_REF
environment variables. If those are not found, Darker works against HEAD
.
Also see --stdin-filename=
for the :STDIN:
special value.
--stdin-filename PATH
The path to the file when passing it through stdin. Useful so Darker can find the
previous version from Git. Only valid with --revision=<rev1>..:STDIN:
(HEAD..:STDIN:
being the default if --stdin-filename
is enabled).
-c PATH, --config PATH
Make darker
, black
and isort
read configuration from PATH
. Note
that other tools like flynt
won't use this configuration file.
-v, --verbose
Show steps taken and summarize modifications
-q, --quiet
Reduce amount of output
--color
Enable syntax highlighting even for non-terminal output. Overrides the
environment variable PY_COLORS=0
--no-color
Disable syntax highlighting even for terminal output. Overrides the environment
variable PY_COLORS=1
-W WORKERS, --workers WORKERS
How many parallel workers to allow, or 0
for one per core [default: 1]
--diff
Don't write the files back, just output a diff for each file on stdout. Highlight
syntax if on a terminal and the pygments
package is available, or if enabled
by configuration.
-d, --stdout
Force complete reformatted output to stdout, instead of in-place. Only valid if
there's just one file to reformat. Highlight syntax if on a terminal and the
pygments
package is available, or if enabled by configuration.
--check
Don't write the files back, just return the status. Return code 0 means nothing
would change. Return code 1 means some files would be reformatted.
-f, --flynt
Also convert string formatting to use f-strings using the flynt
package
-i, --isort
Also sort imports using the isort
package
--preview
In Black, enable potentially disruptive style changes that may be added to Black
in the future
-L CMD, --lint CMD
Show information about baseline linting using the Graylint package.
-S, --skip-string-normalization
Don't normalize string quotes or prefixes
--no-skip-string-normalization
Normalize string quotes or prefixes. This can be used to override skip-string- normalization = true
from a Black configuration file.
--skip-magic-trailing-comma
Skip adding trailing commas to expressions that are split by comma where each
element is on its own line. This includes function signatures. This can be used
to override skip-magic-trailing-comma = true
from a Black configuration file.
-l LENGTH, --line-length LENGTH
How many characters per line to allow [default: 88]
-t VERSION, --target-version VERSION
[py33|py34|py35|py36|py37|py38|py39|py310|py311|py312|py313] Python
versions that should be supported by Black's output. [default: per-file auto-
detection]
--formatter FORMATTER
[black|none] Formatter to use for reformatting code. [default: black]
To change default values for these options for a given project,
add a [tool.darker]
section to pyproject.toml
in the project's root directory,
or to a different TOML file specified using the -c
/ --config
option.
You should configure invoked tools like Black_, isort_ and flynt_ using their own configuration files.
As an exception, the line-length
and target-version
options in [tool.darker]
can be used to override corresponding options for individual tools.
Note that Black_ honors only the options listed in the below example
when called by darker
, because darker
reads the Black configuration
and passes it on when invoking Black_ directly through its Python API.
An example pyproject.toml
configuration file:
.. code-block:: toml
[tool.darker] src = [ "src/mypackage", ] revision = "master" diff = true check = true isort = true flynt = true line-length = 80 # Passed to isort and Black, override their config target-version = ["py312"] # Passed to Black, overriding its config log_level = "INFO"
[tool.black] line-length = 88 # Overridden by [tool.darker] above skip-magic-trailing-comma = false skip-string-normalization = false target-version = ["py38", "py39", "py310", "py311", "py312"] # Overridden above exclude = "test_.py" extend_exclude = "/generated/" force_exclude = "..pyi" preview = true # Only supported in [tool.black]

Install darker
::
$ pip install darker
Locate your darker
installation folder.
On macOS / Linux / BSD::
$ which darker /usr/local/bin/darker # possible location
On Windows::
$ where darker %LocalAppData%\Programs\Python\Python36-32\Scripts\darker.exe # possible location
Open External tools in PyCharm/IntelliJ IDEA
PyCharm -> Preferences -> Tools -> External Tools
File -> Settings -> Tools -> External Tools
Click the +
icon to add a new external tool with the following values:
"$FilePath$"
If you need any extra command line arguments
like the ones which change Black behavior,
you can add them to the Arguments
field, e.g.::
--config /home/myself/black.cfg "$FilePath$"
You can now format the currently opened file by selecting Tools -> External Tools -> Darker
or right clicking on a file and selecting External Tools -> Darker
Optionally, set up a keyboard shortcut at
Preferences or Settings -> Keymap -> External Tools -> External Tools - Darker
Optionally, run darker
on every file save:
Make sure you have the File Watcher
__ plugin installed.
Go to Preferences or Settings -> Tools -> File Watchers
and click +
to add
a new watcher:
$FilePath$
$FilePath$
$ProjectFileDir$
Uncheck "Auto-save edited files to trigger the watcher"
__ https://plugins.jetbrains.com/plugin/7177-file-watchers
Install darker
::
$ pip install darker
Locate your darker
installation folder.
On macOS / Linux / BSD::
$ which darker /usr/local/bin/darker # possible location
On Windows::
$ where darker %LocalAppData%\Programs\Python\Python36-32\Scripts\darker.exe # possible location
Make sure you have the VSCode black-formatter extension
__ installed.
__ https://github.com/microsoft/vscode-black-formatter
Add these configuration options to VSCode
(⌘ Command / Ctrl
+ ⇧ Shift
+ P
and select Open Settings (JSON)
)::
"python.editor.defaultFormatter": "ms-python.black-formatter", "black-formatter.path": "<install_location_from_step_2>", "black-formatter.args": ["-d"],
VSCode will always add --diff --quiet
as arguments to Darker,
but you can also pass additional arguments in the black-formatter.args
option
(e.g. ["-d", "--isort", "--revision=master..."]
).
Note that VSCode first copies the file to reformat into a temporary
<filename>.py.<hash>.tmp
file, then calls Black (or Darker in this case) on that
file, and brings the changes in the modified files back into the editor.
Darker is aware of this behavior, and will correctly compare .py.<hash>.tmp
files
to corresponding .py
files from earlier repository revisions.
Unlike Black_ and many other formatters, darker
needs access to the Git history.
Therefore it does not work properly with classical auto reformat plugins.
You can though ask vim to run darker
on file save with the following in your
.vimrc
:
.. code-block:: vim
set autoread autocmd BufWritePost *.py silent :!darker %
BufWritePost
to run darker
once the file has been saved,silent
to not ask for confirmation each time,:!
to run an external command,%
for current file name.Vim should automatically reload the file.
You can integrate with Emacs using Steve Purcell's emacs-reformatter
__ library.
Using use-package
__:
.. code-block:: emacs-lisp
(use-package reformatter
:hook ((python-mode . darker-reformat-on-save-mode))
:config
(reformatter-define darker-reformat
:program "darker"
:stdin nil
:stdout nil
:args (list "-q" input-file))
This will automatically reformat the buffer on save.
You have multiple functions available to launch it manually:

New in version 1.2.1
To use Darker locally as a Git pre-commit hook for a Python project, do the following:
Install pre-commit_ in your environment
(see pre-commit Installation
_ for details).
Create a base pre-commit configuration::
pre-commit sample-config >.pre-commit-config.yaml
Append to the created .pre-commit-config.yaml
the following lines:
.. code-block:: yaml
install the Git hook scripts and update to the newest version::
pre-commit install
pre-commit autoupdate
When auto-updating, care is being taken to protect you from possible incompatibilities
introduced by Black updates. See Guarding against Black compatibility breakage
_ for
more information.
If you'd prefer to not update but keep a stable pre-commit setup, you can pin Black and other reformatter tools you use to known compatible versions, for example:
.. code-block:: yaml
.. _pre-commit: https://pre-commit.com/ .. _pre-commit Installation: https://pre-commit.com/#installation
You can provide arguments, such as enabling isort, by specifying args
.
Note the inclusion of the isort Python package under additional_dependencies
:
.. code-block:: yaml
You can use Darker within a GitHub Actions workflow without setting your own Python environment. Great for enforcing that modifications and additions to your code match the Black_ code style.
This action is known to support all GitHub-hosted runner OSes. In addition, only
published versions of Darker are supported (i.e. whatever is available on PyPI).
You can search workflows in public GitHub repositories
_ to see how Darker is being
used.
.. _search workflows in public GitHub repositories: https://github.com/search?q=%22uses%3A+akaihola%2Fdarker%22+path%3A%2F%5E.github%5C%2Fworkflows%5C%2F.*%2F&type=code
Create a file named .github/workflows/darker.yml
inside your repository with:
.. code-block:: yaml
name: Reformat
on: [push, pull_request]
jobs: reformat: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 with: fetch-depth: 0 - uses: actions/setup-python@v5 - uses: akaihola/[email protected] with: options: "--check --diff --isort --color" src: "./src" version: "~=2.1.1"
There needs to be a working Python environment, set up using actions/setup-python
in the above example. Darker will be installed in an isolated virtualenv to prevent
conflicts with other workflows.
"uses:"
specifies which Darker release to get the GitHub Action definition from.
We recommend to pin this to a specific release.
"version:"
specifies which version of Darker to run in the GitHub Action.
It defaults to the same version as in "uses:"
,
but you can force it to use a different version as well.
Darker versions available from PyPI are supported, as well as commit SHAs or branch
names, prefixed with an @
symbol (e.g. version: "@master"
).
The revision: "master..."
(or "main..."
) option instructs Darker
to compare the current branch to the branching point from main branch
when determining which source code lines have been changed.
If omitted, the Darker GitHub Action will determine the commit range automatically.
"src:"
defines the root directory to run Darker for.
This is typically the source tree, but you can use "."
(the default)
to also reformat Python files like "setup.py"
in the root of the whole repository.
You can also configure other arguments passed to Darker via "options:"
.
It defaults to "--check --diff --color"
.
You can e.g. add "--isort"
to sort imports, or "--verbose"
for debug logging.
New in version 1.1.0: GitHub Actions integration. Modeled after how Black_ does it, thanks to Black authors for the example!
New in version 1.4.1:
The revision:
option, with smart default value if omitted.
New in version 1.5.0:
The lint:
option.
New in version 3.0.0:
Removed the lint:
option and moved it into the GitHub action
of the Graylint_ package.
Darker automatically enables syntax highlighting for the --diff
and
-d
/--stdout
options if it's running on a terminal and the
Pygments_ package is installed.
You can force enable syntax highlighting on non-terminal output using
color = true
option in the [tool.darker]
section of pyproject.toml
ofPY_COLORS=1
environment variable, and--color
command line option for darker
.You can force disable syntax highlighting on terminal output using
color = false
option in pyproject.toml
,PY_COLORS=0
environment variable, and--no-color
command line option.In the above lists, latter configuration methods override earlier ones, so the command line options always take highest precedence.
.. _Pygments: https://pypi.org/project/Pygments/
Darker accesses some Black internals which don't belong to its public API. Darker is thus subject to becoming incompatible with future versions of Black.
To protect users against such breakage, we test Darker daily against the Black main branch
_ and strive to proactively fix any potential incompatibilities through this
process. If a commit to Black main
branch introduces an incompatibility with
Darker, we will release a first patch version for Darker that prevents upgrading Black
and a second patch version that fixes the incompatibility. A hypothetical example:
main
(after 35.12.0)Black<=35.12.0
If a Black release introduces an incompatibility before the second Darker patch version that fixes it, the first Darker patch version will downgrade Black to the latest compatible version:
Black<=35.12.0
; downgrades to Black 35.12.0To be completely safe, you can pin both Darker and Black to known good versions, but this may prevent you from receiving improvements in Black.
It is recommended to use the '~=
' "compatible release
_" version specifier for
Darker to ensure you have the latest version before the next major release that may
cause compatibility issues.
See issue #382
_ and PR #430
_ for more information.

To apply Black reformatting and to modernize format strings on changed lines, Darker does the following:
git diff
of Python files between REV1
and REV2
as specified using--revision=REV1..REV2
optionTo sort imports when the --isort
option was specified, Darker proceeds like this:
Black doesn't support partial formatting natively. Because of this, Darker lets Black reformat complete files. Darker then accepts or rejects chunks of contiguous lines touched by Black, depending on whether any of the lines in a chunk were edited or added between the two revisions.
Due to the nature of this algorithm, Darker is often unable to minimize the number of changes made by Black as carefully as a developer could do by hand. Also, depending on what kind of changes were made to the code, diff results may lead to Darker applying reformatting in an invalid way. Fortunately, Darker always checks that the result of reformatting converts to the same AST as the original code. If that's not the case, Darker expands the chunk until it finds a valid reformatting. As a result, a much larger block of code may be reformatted than necessary.
The most reasonable work-around to these limitations is to review the changes made by Darker before committing them to the repository and unstaging any changes that are not desired.
