📁 ODir 📁
========

Dealing with paths and directories isn't rocket science, but it can be a
pain. **ODir** allows you to build directory trees by treating your
directory tree as a first-class object.

**Documentation** can be found here
https://opath.readthedocs.io/en/latest/

**without ODir**

.. code:: python

# define paths
top = os.path.abspath('top')
middle = os.path.join(str(top), 'middle')
bottom = os.path.join(str(middle), 'bottom')
os.makedirs(bottom)
with open(os.path.join(bottom, 'bottomlog.txt', 'w') as f:
f.write("some log information")

**with ODir**

.. code:: python

# define paths
env = ODir('top').add('middle').add('bottom').root
env.bottom.write('log.txt', 'w', 'some log information')

Installation
============

Installation via pip is the easiest way...

.. code:: bash

pip install opath

Alternatives
============

Projects like
`pathlib <https://docs.python.org/3/library/pathlib.html>`__ or
`path.py <https://github.com/jaraco/path.py>`__ encapsulating paths into
objects and may be better suited for you purposes.

However, ODir provides some useful features for managing large directory
tree structures. \* building directory and file structure trees as an
abstract tree \* quick access to deeply nested directories and files
using custom attribute names \* directories and files are treated as
nested attributes in python objects

Examples
========

.. figure:: images/dir_example.gif?raw=true
:alt: live\_example

live\_example

Its very easy to create, move, or delete directory trees. For example,
the following builds the directory skeleton for this repo.

.. figure:: images/directory_example.png?raw=true
:alt: demo

demo

.. code:: python

from opath import *

# create folder structure
env = ODir('opath')
env.add('opath', alias='core')
env.core.add('tests')
env.tests.add('env')
env.tests.add('env2')

# make the directory
env.set_dir(Path(__file__).absolute().parent)
env.mkdirs()

# write some files
env.write('README.md', 'w', '# ODir\nThis is a test readme file')
env.core.write("__init__.py", "w", "__version__ = \"1.0\"")

Other things you can do:

Abstracting the directory structure lets your create, remove, copy, move
directory trees easily.

.. figure:: images/rmdirs_example.gif?raw=true
:alt: rmdirs\_example

rmdirs\_example

All paths are easily accessible.

.. code:: python

print(env.test.abspath) # absolute path
print(env.test.path) # relative path

You can even read and write files intuitively.

.. code:: python

# writes file to 'test' folder
env.test.write('test.txt', 'w', 'some data')

# reads test file
env.test.read('test.txt', 'r')

# open file and read lines
env.test.open('test.txt', 'r').readlines()

All iterables are chainable making it easy to do complex things. Pretty
cool!

.. code:: python

# recurseively write a log file to all subfolders of 'core'
env.core.descendents.write('log.txt', 'w', 'some log file')

# read all files named 'log.txt' for subfolders in 'test'
env.test.children.read('log.txt', 'r')

# readlines files named 'log.txt' for subfolders in 'test'
env.test.children.open('log.txt', 'r').readlines()

# recursively get stats on folders
d = env.descendents()
zip(d, d.stat().st_mtime)

Better documentation about chaining methods is soon to come along with
recipes.

Basic usage
===========

Use ``add`` to create folders.

.. code:: python

from opath import *

env = ODir('bin')
env.add('subfolder1')
env.add('subfolder2')
env.print()

>>>
*bin
| *subfolder1
| *subfolder2

Functions return ODir objects and so can be chained together.

.. code:: python

env = ODir('bin')
env.add('subfolder1').add('subsubfolder')
env.print()

>>>
*bin
| *subfolder1
| | *subsubfolder

Files can be written quickly

.. code:: python

env = ODir('bin')
env.add('subfolder1').add('subsubfolder')
env.subsubfolder.write('My Data', 'w')

Or a OFile can be added:

.. code:: python

env = ODir('bin')
env.add_file('myfile.txt', attr='myfile')
env.myfile.write('this is my data', 'w')

Folders create accesible ODir attributes automatically. Alternative
attribute names can be set using 'alias='

.. code:: python

env = ODir('bin')
env.add('subfolder1')
env.subfolder1.add('misc')
env.subfolder1.misc.add('.hidden', alias='hidden')
env.subfolder1.misc.hidden.add('hiddenbin')
env.print()

*bin
| *subfolder1
| | *misc
| | | *.hidden ("hidden")
| | | | *hiddenbin

By default, attributes are *pushed* back the the root directory. The
following is equivalent to above.

.. code:: python

env = ODir('bin')
env.add('subfolder1')
env.subfolder1.add('misc')
env.misc.add('.hidden', alias='hidden')
env.hidden.add('hiddenbin')
env.print()

*bin
| *subfolder1
| | *misc
| | | *.hidden ("hidden")
| | | | *hiddenbin

Making, moving, copying, and deleting directories
=================================================

The location of the root folder can be set by ``set_bin``

.. code:: python

env.set_bin('../bin')

Directories can be created, deleted, copied or moved using ``mkdirs``,
``cpdirs``, ``mvdirs``, ``rmdirs``

.. code:: python

env.mkdirs()
env_copy = env.cpdirs()
# you can do stuff with env_copy independently
env.mvdirs('~/Document')
env_copy.rmdirs()

Advanced usage
==============

All iterables return special list-like objects that can be chained in
one-liners.

.. code:: python

env.descendents() # returns a ChainList object

# find all txt files
env.descendents(include_self=True).glob("*.txt")

# recursively change permissions for directories
env.abspaths.chmod(0o444)
