The Python import sorter tool (https://pycqa.github.io/isort/).

Config section: [isort]

Basic options

skip

--[no-]isort-skip
PANTS_ISORT_SKIP
default: False

Don't use isort when running ./pants fmt and ./pants lint.


args

--isort-args="[<shell_str>, <shell_str>, ...]"
PANTS_ISORT_ARGS
default: []

Arguments to pass directly to isort, e.g. --isort-args="--case-sensitive --trailing-comma".


Advanced options

version

--isort-version=<str>
PANTS_ISORT_VERSION
default: isort[pyproject,colors]>=5.9.3,<6.0

Requirement string for the tool.


extra_requirements

--isort-extra-requirements="['<str>', '<str>', ...]"
PANTS_ISORT_EXTRA_REQUIREMENTS
default: []

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

--isort-interpreter-constraints="['<str>', '<str>', ...]"
PANTS_ISORT_INTERPRETER_CONSTRAINTS
default:
[
  "CPython>=3.7,<4"
]

Python interpreter constraints for this tool.


lockfile

--isort-lockfile=<str>
PANTS_ISORT_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-setup].invalid_lockfile_behavior). See https://github.com/pantsbuild/pants/blob/release_2.8.0.dev2/src/python/pants/backend/python/lint/isort/lockfile.txt 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.

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

Lockfile generation currently does not wire up the [python-repos] options. If lockfile generation fails, you can manually generate a lockfile, such as by using pip-compile or pip freeze. Set this option to the path to your manually generated lockfile. When manually maintaining lockfiles, set [python-setup].invalid_lockfile_behavior = 'ignore'.


console_script

--isort-console-script=<str>
PANTS_ISORT_CONSOLE_SCRIPT
default: isort

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

--isort-entry-point=<str>
PANTS_ISORT_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

--isort-config="[<file_option>, <file_option>, ...]"
PANTS_ISORT_CONFIG
default: []

Path to config file understood by isort (https://pycqa.github.io/isort/docs/configuration/config_files/).

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

If using isort 5+ and you specify only 1 config file, Pants will configure isort's argv to point to your config file.


config_discovery

--[no-]isort-config-discovery
PANTS_ISORT_CONFIG_DISCOVERY
default: True

If true, Pants will include any relevant config files during runs (.isort.cfg, pyproject.toml, setup.cfg, tox.ini and .editorconfig).

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


Deprecated options

None
