Command line help
How to dynamically get more information on Pants's internals.
./pants help to get basic help, including a list of commands you can run to get more specific help:
❯ ./pants help Pants 2.8.0 Usage: ./pants [option ...] [goal ...] [file/target ...] Attempt the specified goals on the specified files/targets. ./pants help Display this usage message. ./pants help goals List all installed goals. ./pants help targets List all installed target types. ./pants help subsystems List all configurable subsystems. ./pants help tools List all external tools. ./pants help global Help for global options. ./pants help-advanced global Help for global advanced options. ./pants help [target_type/goal/subsystem] Help for a target type, goal or subsystem. ./pants help-advanced [goal/subsystem] Help for a goal or subsystem's advanced options. ./pants help-all Print a JSON object containing all help info. [file] can be: path/to/file.ext A path glob, such as '**/*.ext', in quotes to prevent premature shell expansion. [target] can be: path/to/dir:target_name. path/to/dir for a target whose name is the same as the directory name. path/to/dir: to include all targets in the specified directory. path/to/dir:: to include all targets found recursively under the directory.

For example, to get help on the
$ ./pants help test `test` goal options ------------------- Run tests. Config section: [test] --[no-]test-debug PANTS_TEST_DEBUG debug default: False current value: False Run tests sequentially in an interactive process. This is necessary, for example, when you add breakpoints to your code. --[no-]test-force PANTS_TEST_FORCE force default: False current value: False Force the tests to run, even if they could be satisfied from cache. ... Related subsystems: coverage-py, download-pex-bin, pants-releases, pex, pex-binary-defaults, pytest, python-infer, python-native-code, python-repos, python-setup, setup-py-generation, setuptools, source, subprocess-environment
Note that when you run
./pants help <goal>, it outputs all related subsystems, such as
pytest. You can then run
./pants help pytest to get more information.
You can also run
./pants help goals and
./pants help subsystems to get a list of all activated options scopes.
To get help on the
❯ ./pants help python_test `python_test` target -------------------- A single Python test file, written in either Pytest style or unittest style. All test util code, including `conftest.py`, should go into a dedicated `python_source` target and then be included in the `dependencies` field. (You can use the `python_test_utils` target to generate these `python_source` targets.) See https://www.pantsbuild.org/v2.8/docs/python-test-goal Valid fields: timeout type: int | None default: None A timeout (in seconds) used by each test file belonging to this target. This only applies if the option `--pytest-timeouts` is set to True. ...
Many options are classified as advanced, meaning they are primarily intended to be used by admins, not by regular users.
./pants help-advanced global or
./pants help-advanced pytest.
