  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
  .flake8rc
  pylama.ini
  pylintrc
  .pylintrc
  Pipfile
  Pipfile.lock
<

The first directory containing any of the files named above will be used.

  Default: `'bandit'`

  See |ale-integrations-local-executables|

  Set this to `'pipenv'` to invoke `'pipenv` `run` `bandit'`.

  Type: |Number|
  Default: `1`

  If this variable is true and a `.bandit` file exists in the directory of the
  file being checked or a parent directory, an `--ini` option is added to the
  `bandit` command for the nearest `.bandit` file.  Set this variable false to
  disable adding the `--ini` option automatically.

  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.

g:ale_python_black_change_directory       *g:ale_python_black_change_directory*
                                          *b:ale_python_black_change_directory*
  Type: |Number|
  Default: `1`

  If set to `1`, ALE will switch to the directory the Python file being
  checked with `black` is in before checking it. This helps `black` find
  configuration files more easily. This option can be turned off if you want
  to control the directory Python is executed from yourself.


===============================================================================
flake8                                                      *ale-python-flake8*

  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.

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|.

  Default: `'mypy'`

  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*

  invocation.

  Type: |String|
  Default: `''`

  This variable can be changed to add command-line arguments to the prospector
  invocation.

  For example, to dynamically switch between programs targeting Python 2 and
  Python 3, you may want to set >

  let g:ale_python_prospector_executable = 'python3'
  " or 'python' for Python 2
  let g:ale_python_prospector_options = '--rcfile /path/to/.prospector.yaml'
  " 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`).

  Default: `1`

  If set to `1`, `pylama` will be run from a detected project root, per
  |ale-python-root|.  This is useful because `pylama` only searches for
  configuration files in its current directory and applies file masks using
  paths relative to its current directory.  This option can be turned off if
  you want to control the directory in which `pylama` is executed.

  Type: |String|
  Default: `''`

  This variable can be changed to add command-line arguments to the pylama
  invocation.


g:ale_python_pylama_use_global                 *g:ale_python_pylama_use_global*
                                               *b:ale_python_pylama_use_global*
  Type: |Number|
  Default: `get(g:, 'ale_use_global_executables', 0)`

  This variable controls whether or not ALE will search for pylama in a
  virtualenv directory first. If this variable is set to `1`, then ALE will
  always use |g:ale_python_pylama_executable| for the executable path.

  Both variables can be set with `b:` buffer variables instead.


g:ale_python_pylama_auto_pipenv               *g:ale_python_pylama_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.

  Type: |Number|
  Default: `1`

  If set to `1`, `pylint` will be run from a detected project root, per
  |ale-python-root|.  Since `pylint` only checks for `pylintrc` in the packages
  above its current directory before falling back to user and global `pylintrc`
  files, this is necessary for `pylint` to use a project `pylintrc` file, if
  present.  This option can be turned off if you want to control the directory
  Python is executed from yourself.

                                               *b:ale_python_pylint_executable*
  Type: |String|
  Default: `'pylint'`

  See |ale-integrations-local-executables|

  Set this to `'pipenv'` to invoke `'pipenv` `run` `pylint'`.

  Type: |String|
  Default: `''`

  This variable can be changed to add command-line arguments to the pylint
  invocation.

  For example, to dynamically switch between programs targeting Python 2 and
  Python 3, you may want to set >

  let g:ale_python_pylint_executable = 'python3'   " or 'python' for Python 2
  let g:ale_python_pylint_options = '--rcfile /path/to/pylint.rc'
  " The virtualenv detection needs to be disabled.
  let g:ale_python_pylint_use_global = 0

  after making sure it's installed for the appropriate Python versions (e.g.
  `python3 -m pip install --user pylint`).

  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.


g:ale_python_pylint_use_msg_id                 *g:ale_python_pylint_use_msg_id*
                                               *b:ale_python_pylint_use_msg_id*
  Type: |Number|
  Default: `0`

  Use message for output (e.g. I0011) instead of symbolic name of the message
  (e.g. locally-disabled).

  If set to `1`, ALE will switch to the directory the Python file being
  checked with `vulture` is in before checking it and check the whole project
  directory instead of checking only the file opened in the current buffer.
