ALE Python Integration                                     *ale-python-options*


-------------------------------------------------------------------------------
Global Options

g:ale_virtualenv_dir_names                         *g:ale_virtualenv_dir_names*
                                                   *b:ale_virtualenv_dir_names*

  Type: |List|
  Default: `['.env', 'env', 've', 've-py3', 'virtualenv']`

  A list of directory names to be used when searching upwards from Python
  files to discover virtulenv directories with. For directory named `'foo'`,
  ALE will search for `'foo/bin/activate'` in all directories on and above
  the directory containing the Python file to find virtualenv paths.


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

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.


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: `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.


-------------------------------------------------------------------------------
mypy                                                          *ale-python-mypy*

g:ale_python_mypy_executable                     *g:ale_python_mypy_executable*
                                                 *b:ale_python_mypy_executable*
  Type: |String|
  Default: `'mypy'`

  This variable can be changed to modify the executable used for mypy.


g:ale_python_mypy_options                           *g:ale_python_mypy_options*
                                                    *b:ale_python_mypy_options*
  Type: |String|
  Default: `''`

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


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

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

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


-------------------------------------------------------------------------------
pylint                                                      *ale-python-pylint*

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

  This variable can be changed to modify the executable used for pylint.


g:ale_python_pylint_options                       *g:ale_python_pylint_options*
                                                  *b:ale_python_pylint_options*
  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`).


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

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

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