Description: Vulture - Find dead code
        ========================
        
        .. image:: https://travis-ci.org/jendrikseipp/vulture.svg?branch=master
           :target: https://travis-ci.org/jendrikseipp/vulture
        
        Vulture finds unused code in Python programs. This is useful for
        cleaning up and finding errors in large code bases. If you run Vulture
        on both your library and test suite you can find untested code.
        
        Due to Python's dynamic nature, static code analyzers like Vulture are
        likely to miss some dead code. Also, code that is only called implicitly
        may be reported as unused. Nonetheless, Vulture can be a very helpful
        tool for higher code quality.
        
        
        Features
        --------
        
        * fast: static code analysis
        * lightweight: only one module
        * tested: tests itself and has complete test coverage
        * complements pyflakes and has the same output syntax
        * sorts unused classes and functions by size with `--sort-by-size`
        * supports Python 2.6, 2.7 and 3.x
        
        
        Installation
        ------------
        
        ::
        
          $ pip install vulture  # from PyPI
          $ pip install .        # from cloned repo
        
        
        Usage
        -----
        
        ::
        
          $ vulture myscript.py  # or
          $ python3 -m vulture myscript.py
          $ vulture myscript.py mypackage1/ mypackage2/
          $ vulture myscript.py mywhitelist.py
        
        The provided arguments may be Python files or directories. For each
        directory Vulture analyzes all contained `*.py` files.
        
        After you have found and deleted dead code, run Vulture again, because
        it may discover more dead code.
        
        **Handling false positives**
        
        You can add used code that is reported as unused to a Python module and
        add it to the list of scanned paths. We collect whitelists for common
        Python modules and packages in ``vulture/whitelists/`` (pull requests
        are welcome). If you want to ignore a whole file or directory, use the
        ``--exclude`` parameter (e.g., ``-exclude *settings.py,docs/``).
        
        
        How does it work?
        -----------------
        
        Vulture uses the ``ast`` module to build abstract syntax trees for all
        given files. While traversing all syntax trees it records the names of
        defined and used objects. Afterwards, it reports the objects which have
        been defined, but not used. This analysis ignores scopes and focuses
        only on object names.
        
        
        Sort by size
        ------------
        
        When using the ``--sort-by-size`` option, Vulture sorts unused classes
        and functions by their lines of code. This helps developers prioritize
        where to look for dead code first.
        
        
        Similar programs
        ----------------
        
        * Vulture can be used together with *pyflakes*
        * The *coverage* module can find unused code more reliably, but requires
          all branches of the code to actually be run.
