A formatter for Python files (https://github.com/google/yapf).

Backend: pants.core
Config section: [yapf]

Basic options

skip

--[no-]yapf-skip

PANTS_YAPF_SKIP

default: False

If true, don't use yapf when running ./pants fmt and ./pants lint.


args

--yapf-args="[<shell_str>, <shell_str>, ...]"

PANTS_YAPF_ARGS

default: []

Arguments to pass directly to yapf, e.g. --yapf-args='--no-local-style'.

Certain arguments, specifically --recursive, --in-place, and --parallel, will be ignored because Pants takes care of finding all the relevant files and running the formatting in parallel.


export

--[no-]yapf-export

PANTS_YAPF_EXPORT

default: True

If true, export a virtual environment with yapf when running ./pants export.

This can be useful, for example, with IDE integrations to point your editor to the tool's binary.


Advanced options

version

--yapf-version=<str>

PANTS_YAPF_VERSION

default: yapf==0.32.0

Requirement string for the tool.


extra_requirements

--yapf-extra-requirements="['<str>', '<str>', ...]"

PANTS_YAPF_EXTRA_REQUIREMENTS

default:
[
  "toml"
]

Any additional requirement strings to use with the tool. This is useful if the tool allows you to install plugins or if you need to constrain a dependency to a certain version.


interpreter_constraints

--yapf-interpreter-constraints="['<str>', '<str>', ...]"

PANTS_YAPF_INTERPRETER_CONSTRAINTS

default:
[
  "CPython>=3.7,<4"
]

Python interpreter constraints for this tool.


lockfile

--yapf-lockfile=<str>

PANTS_YAPF_LOCKFILE

default: <default>

Path to a lockfile used for installing the tool.

Set to the string <default> to use a lockfile provided by Pants, so long as you have not changed the --version and --extra-requirements options, and the tool's interpreter constraints are compatible with the default. Pants will error or warn if the lockfile is not compatible (controlled by [python].invalid_lockfile_behavior). See https://github.com/pantsbuild/pants/blob/release_2.14.2rc2/src/python/pants/backend/python/lint/yapf/yapf.lock for the default lockfile contents.

Set to the string <none> to opt out of using a lockfile. We do not recommend this, though, as lockfiles are essential for reproducible builds and supply-chain security.

To use a custom lockfile, set this option to a file path relative to the build root, then run ./pants generate-lockfiles --resolve=yapf.

Alternatively, you can set this option to the path to a custom lockfile using pip's requirements.txt-style, ideally with --hash. Set [python].invalid_lockfile_behavior = 'ignore' so that Pants does not complain about missing lockfile headers.


console_script

--yapf-console-script=<str>

PANTS_YAPF_CONSOLE_SCRIPT

default: yapf

The console script for the tool. Using this option is generally preferable to (and mutually exclusive with) specifying an --entry-point since console script names have a higher expectation of staying stable across releases of the tool. Usually, you will not want to change this from the default.


entry_point

--yapf-entry-point=<str>

PANTS_YAPF_ENTRY_POINT

default: None

The entry point for the tool. Generally you only want to use this option if the tool does not offer a --console-script (which this option is mutually exclusive with). Usually, you will not want to change this from the default.


config

--yapf-config=<file_option>

PANTS_YAPF_CONFIG

default: None

Path to style file understood by yapf (https://github.com/google/yapf#formatting-style/).

Setting this option will disable [yapf].config_discovery. Use this option if the config is located in a non-standard location.


config_discovery

--[no-]yapf-config-discovery

PANTS_YAPF_CONFIG_DISCOVERY

default: True

If true, Pants will include any relevant config files during runs (.style.yapf, pyproject.toml, and setup.cfg).

Use [yapf].config instead if your config is in a non-standard location.


Deprecated options

None
