Official Python Pachyderm Client

Created by [kalugny](https://github.com/kalugny)

(Formerly kalugny/pypachy)



Python Pachyderm Client

A python client wrapper for the Pachyderm_ API.

*Notes*:

* Currently implements the PFS interface and only alpha support for the PPS interface.

* Supports Pachyderm versions 1.4 and up.

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

.. code:: bash

pip install pypachy

Usage and options
=================

All of the PFS functions used in ``pachctl`` are supported (almost) as-is.

There are some helper functions that help make things more pythonic:

* ``commit`` which is a context manager wrapper for ``start_commit`` and ``finish_commit``
* ``get_files`` which supports getting the data from multiple files

Naming commits
--------------

All functions that accept a ``commit`` argument will accept a tuple of ``(repo, branch)`` or ``(repo, commit_id)``,
a string like ``repo/branch`` or ``repo/commit_id`` and a Commit object.

e.g:

.. code:: python

>>> client.list_file(('my_repo', 'branch'), '/') # tuple
>>> client.list_file('my_repo/commit_id', '/') # string
>>> c = client.list_commit('my_repo')[0] # get some commit
>>> client.list_file(c, '/') # and use it directly

Basic usage example
-------------------

.. code:: python

>>> import pypachy

>>> client = pypachy.PfsClient()
>>> client.create_repo('test')
>>> with client.commit('test', 'master') as c:
...: client.put_file_bytes(c, '/dir_a/data', b'DATA')
...: client.put_file_url(c, '/dir_b/icon.png', 'http://www.pearl-guide.com/forum/images/smilies/biggrin.png')
...:
>>> client.get_files('test/master', '/', recursive=True)
{'/dir_a/data': b'DATA',
'/dir_b/icon.png': b'\x89PNG\r\n\x1a\n\x00\x00\x00\rIHDR\x00\x00\x00\x10\x00\x00\x00\x10\x08...'}

As of version 0.1.4, there is also limited support for PPS:

.. code:: python

>>> pps_client = pypachy.PpsClient()
>>> pps_client.list_pipeline()
...

To Do
=====

* Achieve full test coverage for PFS and PPS.
* Add support for ``description`` field in ``Commit``.
* Add support for ``ObjectAPI``
