python_sources
Generate a python_source
target for each file in the sources
field.
You can either use this target generator or python_test_utils
for test utility files like conftest.py
. They behave identically, but can help to better model and keep separate test support files vs. production files.
Backend: pants.backend.python
dependencies
Iterable[str] | None
None
Addresses to other targets that this target depends on, e.g. ['helloworld/subdir:lib', 'helloworld/main.py:lib', '3rdparty:reqs#django'].
This augments any dependencies inferred by Pants, such as by analyzing your imports. Use /home/josh/work/scie-pants/dist/pants dependencies
or /home/josh/work/scie-pants/dist/pants peek
on this target to get the final result.
See https://www.pantsbuild.org/v2.11/docs/targets#target-addresses and https://www.pantsbuild.org/v2.11/docs/targets#target-generation for more about how addresses are formed, including for generated targets. You can also run /home/josh/work/scie-pants/dist/pants list ::
to find all addresses in your project, or /home/josh/work/scie-pants/dist/pants list dir:
to find all addresses defined in that directory.
If the target is in the same BUILD file, you can leave off the BUILD file path, e.g. :tgt
instead of helloworld/subdir:tgt
. For generated first-party addresses, use ./
for the file path, e.g. ./main.py:tgt
; for all other generated targets, use :tgt#generated_name
.
You may exclude dependencies by prefixing with !
, e.g. ['!helloworld/subdir:lib', '!./sibling.txt']
. Ignores are intended for false positives with dependency inference; otherwise, simply leave off the dependency from the BUILD file.
description
str | None
None
A human-readable description of the target.
Use /home/josh/work/scie-pants/dist/pants list --documented ::
to see all targets with descriptions.
interpreter_constraints
Iterable[str] | None
None
The Python interpreters this code is compatible with.
Each element should be written in pip-style format, e.g. CPython==2.7.*
or CPython>=3.6,<4
. You can leave off CPython
as a shorthand, e.g. >=2.7
will be expanded to CPython>=2.7
.
Specify more than one element to OR the constraints, e.g. ['PyPy==3.7.*', 'CPython==3.7.*']
means either PyPy 3.7 or CPython 3.7.
If the field is not set, it will default to the option [python].interpreter_constraints
.
See https://www.pantsbuild.org/v2.11/docs/python-interpreter-compatibility for how these interpreter constraints are merged with the constraints of dependencies.
overrides
Dict[Union[str, Tuple[str, ...]], Dict[str, Any]] | None
None
Override the field values for generated python_source
targets.
Expects a dictionary of relative file paths and globs to a dictionary for the overrides. You may either use a string for a single path / glob, or a string tuple for multiple paths / globs. Each override is a dictionary of field names to the overridden value.
For example:
overrides={
"foo.py": {"skip_pylint": True]},
"bar.py": {"skip_flake8": True]},
("foo.py", "bar.py"): {"tags": ["linter_disabled"]},
}
File paths and globs are relative to the BUILD file's directory. Every overridden file is validated to belong to this target's sources
field.
If you'd like to override a field's value for every python_source
target generated by this target, change the field directly on this target rather than using the overrides
field.
You can specify the same file name in multiple keys, so long as you don't override the same field more than one time for the file.
resolve
str | None
None
The resolve from [python].resolves
to use.
If not defined, will default to [python].default_resolve
.
All dependencies must share the same value for their resolve
field.
skip_autoflake
bool
False
pants.backend.experimental.python.lint.autoflake
If true, don't run Autoflake on this target's code.
skip_bandit
bool
False
pants.backend.python.lint.bandit
If true, don't run Bandit on this target's code.
skip_black
bool
False
pants.backend.python.lint.black
If true, don't run Black on this target's code.
skip_docformatter
bool
False
pants.backend.python.lint.docformatter
If true, don't run Docformatter on this target's code.
skip_flake8
bool
False
pants.backend.python.lint.flake8
If true, don't run Flake8 on this target's code.
skip_isort
bool
False
pants.backend.python.lint.isort
If true, don't run isort on this target's code.
skip_mypy
bool
False
pants.backend.python.typecheck.mypy
If true, don't run MyPy on this target's code.
skip_pylint
bool
False
pants.backend.python.lint.pylint
If true, don't run Pylint on this target's code.
skip_pyupgrade
bool
False
pants.backend.experimental.python.lint.pyupgrade
If true, don't run pyupgrade on this target's code.
skip_yapf
bool
False
pants.backend.python.lint.yapf
If true, don't run yapf on this target's code.
sources
Iterable[str] | None
('*.py', '*.pyi', '!test_*.py', '!*_test.py', '!tests.py', '!conftest.py', '!test_*.pyi', '!*_test.pyi', '!tests.pyi')
A list of files and globs that belong to this target.
Paths are relative to the BUILD file's directory. You can ignore files/globs by prefixing them with !
.
Example: sources=['example.ext', 'test_*.ext', '!test_ignore.ext']
.
tags
Iterable[str] | None
None
Arbitrary strings to describe a target.
For example, you may tag some test targets with 'integration_test' so that you could run /home/josh/work/scie-pants/dist/pants --tag='integration_test' test ::
to only run on targets with that tag.
