Package: dirtools
==========Dirtools==========Dirtools is a little Python package aimed to provide the following features:* Exclude/ignore files in a directory, using .gitignore like syntax (unix filename pattern matching).* Generate a hash for a directory tree in order to check if a directory has been modified.* Search recursively for all subidirs containing a given filename (all projects directory inside a dir).* Track changes in a directory over time (without duplicating it or without having direct access to it)... image:: https://pypip.in/v/dirtools/badge.png:target: https://crate.io/packages/dirtools.. image:: https://pypip.in/d/dirtools/badge.png:target: https://crate.io/packages/dirtoolsInstallation============.. code-block::$ pip install dirtoolsGetting Started===============Excluding files---------------Dirtools let you exlude files using .gitignore like syntax (unix filename pattern matching), by default ``dirtools`` will look for a ``.exclude`` file at root.Here is how to check if a file should be excluded:.. code-block:: pythonfrom dirtools import Dird = Dir('/path/to/dir', exclude_file='.gitignore')d.is_excluded('/path/to/dir/script.pyc')Hashdir-------The hashdir represent the state of every files in a directory. It compute the hash of the hash of each file recursively.Here is how to compute the hash of a directory, excluded files ares skipped if any... code-block:: pythonfrom dirtools import Dird = Dir('/path/to/dir')hashdir = d.hash()Find directories containing a file----------------------------------We'll call these directories **project**, ``find_projects`` will search recursively for subdirectories with a ``file_identifier`` file in it... code-block:: pythonfrom dirtools import Dird = Dir('/path/to/dir')projects = d.find_projects('.project')Compress the directory with gzip----------------------------------Dirtools provides a helper to compress the whole directory (except excluded files/dirs) with gzip... code-block:: pythonfrom dirtools import Dird = Dir('/path/to/dir')# By default, dirtools will create a temporary file to store the archive for youtmp_archive = d.compress_to()# But you can specify a filearchive_path = '/home/thomas/mydir.tgz'd.compress_to(archive_path)Or if you want to do it manually:.. code-block:: pythonimport tarfilefrom dirtools import Dird = Dir('/path/to/mydir', exclude_file='.gitignore')with tarfile.open(fileobj=out, mode="w:gz")) as tar:tar.add(filename, arcname=arcname, exclude=d.is_excluded)Track changes in directories----------------------------Dirtools provides an helper ``DirState`` to help tracking changes in a directory over time, without duplicating it or without having direct access to it... code-block:: pythonfrom dirtools import Dir, DirStated = Dir(path)dir_state = DirState(d)state_file = dir_state.to_json()# Later... after some changesdir_state = DirState.from_json(state_file)dir_state2 = DirState(d)changes = dir_state2 - dir_stateHelpers-------All methods/properties exclude files and directories based on patterns in ``exclude_file`` and the ``excludes`` list.Custom Walker~~~~~~~~~~~~~If you need to perform operations on files or directories, you can use ``Dir.walk``, it works exactly like ``os.walk``, except it will skip excluded files/directories on the fly... code-block:: pythonfrom dirtools import Dird = Dir('/path/to/dir')for root, dirs, files in self.walk():# do somethingList all subdirectories of a directory~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~.. code-block:: pythonfrom dirtools import Dird = Dir('/path/to/dir')dirs = d.subdirs()myproject_dirs = d.subdirs('myproject_*')List all files recursively~~~~~~~~~~~~~~~~~~~~~~~~~.. code-block:: pythonfrom dirtools import Dird = Dir('/path/to/dir')files = d.files()py_files = d.files('*.py')License (MIT)=============Copyright (c) 2013 Thomas SileoPermission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions:The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
