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.

  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*

  Default: `'flake8'`

  This variable can be changed to modify the executable used for flake8. Set
  this to `'pipenv'` to invoke `'pipenv` `run` `flake8'`.

  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`).

  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.

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|.

  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.

  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.

`pyre` will be run from a detected project root, per |ale-python-root|.

  Default: `'pyre'`

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

  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`, 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.
  This helps `vulture` to know the context and avoid false-negative results.
