The linter can correctly parse pydocstyle output with any of the following
command-line options enabled: --explain, --source, --debug, and/or
--verbose

ALE Python Integration *ale-python-options*
g:ale_python_auto_pipenv *g:ale_python_auto_pipenv*
*b:ale_python_auto_pipenv*
Type: |Number|
Default: `0`
Detect whether the file is inside a pipenv, and set the executable to `pipenv`
if true. This is overridden by a manually-set executable.
===============================================================================
ALE Python Project Root Behavior *ale-python-root*
For some linters, ALE will search for a Python project root by looking at the
files in directories on or above where a file being checked is. ALE applies
the following methods, in order:
1. Find the first directory containing a common Python configuration file.
2. If no configuration file can be found, use the first directory which does
not contain a readable file named `__init__.py`.
ALE will look for configuration files with the following filenames. >
MANIFEST.in
setup.cfg
pytest.ini
tox.ini
mypy.ini
pycodestyle.cfg
flake8.cfg
.flake8rc
Pipfile
Pipfile.lock
<
The first directory containing any of the files named above will be used.
===============================================================================
autopep8 *ale-python-autopep8*
g:ale_python_autopep8_executable *g:ale_python_autopep8_executable*
*b:ale_python_autopep8_executable*
Type: |String|
Default: `'autopep8'`
See |ale-integrations-local-executables|
g:ale_python_autopep8_options *g:ale_python_autopep8_options*
*b:ale_python_autopep8_options*
Type: |String|
Default: `''`
This variable can be set to pass extra options to autopep8.
g:ale_python_autopep8_use_global *g:ale_python_autopep8_use_global*
*b:ale_python_autopep8_use_global*
Type: |Number|
Default: `get(g:, 'ale_use_global_executables', 0)`

autopep8
g:ale_python_black_options *g:ale_python_black_options*
*b:ale_python_black_options*
Type: |String|
Default: `''`
This variable can be set to pass extra options to black.
g:ale_python_black_use_global *g:ale_python_black_use_global*
*b:ale_python_black_use_global*
Type: |Number|
Default: `get(g:, 'ale_use_global_executables', 0)`

===============================================================================
flake8 *ale-python-flake8*
g:ale_python_flake8_change_directory *g:ale_python_flake8_change_directory*
*b:ale_python_flake8_change_directory*
Type: |Number|
Default: `1`
If set to `1`, ALE will switch to the directory the Python file being
checked with `flake8` is in before checking it. This helps `flake8` find
configuration files more easily. This option can be turned off if you want
to control the directory Python is executed from yourself.
g:ale_python_flake8_executable *g:ale_python_flake8_executable*
*b:ale_python_flake8_executable*
Type: |String|
Default: `'flake8'`
This variable can be changed to modify the executable used for flake8. Set
this to `'pipenv'` to invoke `'pipenv` `run` `flake8'`.
g:ale_python_flake8_options *g:ale_python_flake8_options*
*b:ale_python_flake8_options*
Type: |String|
Default: `''`
This variable can be changed to add command-line arguments to the flake8
invocation.
For example, to dynamically switch between programs targeting Python 2 and
Python 3, you may want to set >
let g:ale_python_flake8_executable = 'python3' " or 'python' for Python 2
let g:ale_python_flake8_options = '-m flake8'
<
after making sure it's installed for the appropriate Python versions (e.g.
`python3 -m pip install --user flake8`).
g:ale_python_flake8_use_global *g:ale_python_flake8_use_global*
*b:ale_python_flake8_use_global*
Type: |Number|
Default: `get(g:, 'ale_use_global_executables', 0)`
This variable controls whether or not ALE will search for flake8 in a
virtualenv directory first. If this variable is set to `1`, then ALE will
always use |g:ale_python_flake8_executable| for the executable path.
Both variables can be set with `b:` buffer variables instead.
g:ale_python_flake8_auto_pipenv *g:ale_python_flake8_auto_pipenv*
*b:ale_python_flake8_auto_pipenv*
Type: |Number|
Default: `0`
Detect whether the file is inside a pipenv, and set the executable to `pipenv`
if true. This is overridden by a manually-set executable.

mypy *ale-python-mypy*
The minimum supported version of mypy that ALE supports is v0.4.4. This is
the first version containing the `--shadow-file` option ALE needs to be able
to check for errors while you type.
`mypy` will be run from a detected project root, per |ale-python-root|.
g:ale_python_mypy_executable *g:ale_python_mypy_executable*
*b:ale_python_mypy_executable*
Type: |String|

g:ale_python_mypy_ignore_invalid_syntax
*g:ale_python_mypy_ignore_invalid_syntax*
*b:ale_python_mypy_ignore_invalid_syntax*
Type: |Number|
Default: `0`
When set to `1`, syntax error messages for mypy will be ignored. This option
can be used when running other Python linters which check for syntax errors,
as mypy can take a while to finish executing.
g:ale_python_mypy_options *g:ale_python_mypy_options*
*b:ale_python_mypy_options*

*b:ale_python_mypy_auto_pipenv*

" The virtualenv detection needs to be disabled.
let g:ale_python_prospector_use_global = 0
after making sure it's installed for the appropriate Python versions (e.g.
`python3 -m pip install --user prospector`).
