        Overview
        --------
        
        ``node.ext.directory`` is a node implementation for file system directories.
        
        For more information about ``node`` see
        `https://pypi.python.org/pypi/node <https://pypi.python.org/pypi/node>`_.
        
        
        Usage
        -----
        
        Create new file:
        
        .. code-block:: python
        
            from node.ext.directory import File
        
            file_path = 'file.txt'
            f = File(name=file_path)
        
            # set contents via data attribute
            f.data = 'data\n'
        
            # set contents via lines attribute
            f.lines = ['data']
        
            # set permissions
            f.fs_mode = 0o644
        
            # persist
            f()
        
        Read existing file:
        
        .. code-block:: python
        
            file_path = 'file.txt'
            f = File(name=file_path)
        
            assert(f.data == 'data\n')
            assert(f.lines == ['data'])
            assert(f.fs_mode == 0o644)
        
        Files with binary data:
        
        .. code-block:: python
        
            from node.ext.directory import MODE_BINARY
        
            file_path = 'file.txt'
            f = File(name=file_path)
            f.mode = MODE_BINARY
        
            f.data = b'\x00\x00'
        
            assert(f.data == b'\x00\x00')
        
            # lines property won't work if file in binary mode
            f.lines  # raises RuntimeError
        
        Create directory:
        
        .. code-block:: python
        
            from node.ext.directory import Directory
        
            dir_path = '.'
            d = Directory(name=dir_path)
        
            # add subdirectories and files
            d['sub'] = Directory()
            d['file.txt'] = File()
        
            # set permissions for directory
            d['sub'].fs_mode = 0o755
        
            # persist
            d()
        
        Read existing directory:
        
        .. code-block:: python
        
            dir_path = '.'
            d = Directory(name=dir_path)
        
        .. code-block:: pycon
        
            >>> d.printtree()
            <class 'node.ext.directory.directory.Directory'>: .
              <class 'node.ext.directory.directory.File'>: file.txt
              <class 'node.ext.directory.directory.Directory'>: sub
        
        Define file factories:
        
        .. code-block:: python
        
            from node.ext import directory
        
            class PyFile(File):
                pass
        
            # set global factories
            directory.file_factories['.py'] = PyFile
        
            # set local factories
            d = Directory(name='.', factories={'.py': PyFile})
        
        when reading .py files, PyFile is used to instanciate children:
        
        .. code-block:: pycon
        
            >>> with open('foo.py', 'w') as f:
            ...     f.write('#')
        
            >>> d = Directory(name='.', factories={'.py': PyFile})
            >>> d.printtree()
            <class 'node.ext.directory.directory.Directory'>: .
              <class '...PyFile'>: foo.py

        Changes
        =======
        
        0.8 (2022-03-21)
        ----------------
        
        - Replace deprecated use of ``Nodify`` by ``MappingNode``.
          [rnix]
        
        - Replace deprecated use of ``Adopt`` by ``MappingAdopt``.
          [rnix]
        
        
        0.7
        ---
        
        - Python 3 support.
          [rnix, 2017-06-06]
        
        - ``fs_mode`` is read from filesystem if file or directory exists and
          fs_mode not set explicitely.
          [rnix, 2017-06-06]
        
        - Remove ``backup`` option from ``IDirectory`` interface. It never really
          worked properly and conceptually ``IDirectory`` is the wrong place for
          handling backups of files.
          [rnix, 2017-06-04]
        
        
        0.6
        ---
        
        - Introduce ``node.ext.directory.interfaces.IFile.direct_sync`` setting.
          [rnix, 2017-01-30]
        
        - Complete ``node.ext.directory.interfaces.IFile`` and
          ``node.ext.directory.interfaces.IDirectory`` to reflect implemented features.
          [rnix, 2017-01-30]
        
        - Move ``node.ext.directory.directory.MODE_TEXT`` and
          ``node.ext.directory.directory.MODE_BINARY`` to
          ``node.ext.directory.interfaces``.
          [rnix, 2017-01-30]
        
        
        0.5.4
        -----
        
        - Check whether directory to be peristed already exists by name as file in
          ``node.ext.directory.FileStorage.__call__``.
          [rnix, 2015-10-05]
        
        - Implement fallback to ``path`` in
          ``node.ext.directory.FileStorage.__call__`` if ``fs_path`` not exists.
          [rnix, 2015-10-05]
        
        - Implement fallback to ``path`` in
          ``node.ext.directory.FileStorage._get_data`` if ``fs_path`` not exists.
          [rnix, 2015-10-05]
        
        - Set initial mode with ``self.mode`` property setter instead of internal
          ``self._mode`` in ``node.ext.directory.FileStorage._get_mode``.
          [rnix, 2015-10-05]
        
        
        0.5.3
        -----
        
        - Remove deleted keys from internal reference after ``__call__`` in order
          to return the correct result when adding a file or directory with the same
          key again.
          [rnix, 2015-07-20]
        
        
        0.5.2
        -----
        
        - Use try/except instead of iteration to check whether directory child already
          in memory.
          [rnix, 2015-05-12]
        
        
        0.5.1
        -----
        
        - Always use ``os.chmod`` for setting directory permissions, not only if
          already exists.
          [rnix, 2015-03-03]
        
        
        0.5
        ---
        
        - Introduce ``fs_mode`` on directories and files.
          [rnix, 2015-03-03]
        
        
        0.4
        ---
        
        - Return empty list in ``File.lines`` if no data.
          [rnix, 2015-02-18]
        
        - Consider filesystem encoding. Defaults to UTF-8.
          [rnix, 2015-02-18]
        
        - Tree locking on modification.
          [rnix, 2014-09-02]
        
        - Prevent empty keys in ``__setitem__``.
          [rnix, 2014-09-02]
        
        - Use ``plumbing`` decorator.
          [rnix, 2014-08-25]
        
        
        0.3
        ---
        
        - introduce ``default_file_factory`` on directories for controlling default
          file child creation.
          [rnix, 2013-12-09]
        
        - move file logic in ``FileStorage`` behavior.
          [rnix, 2013-08-06]
        
        - make ``file_factories`` a class property on directory storage.
          [rnix, 2013-08-06]
        
        - make ``ignores`` a class property on directory storage.
          [rnix, 2013-08-06]
        
        - Cleanup interfaces.
          [rnix, 2013-08-06]
        
        
        0.2
        ---
        
        - Almost complete rewrite. Fits now paradigms of node based API's.
          [rnix, 2012-01-30]
        
        
        0.1
