Dulwich
=======

This is the Dulwich project.

It aims to provide an interface to git repos (both local and remote) that
doesn't call out to git directly but instead uses pure Python.

**Main website**: <https://www.dulwich.io/>

**License**: Apache License, version 2 or GNU General Public License, version 2 or later.

The project is named after the part of London that Mr. and Mrs. Git live in
in the particular Monty Python sketch.

Installation
------------

By default, Dulwich' setup.py will attempt to build and install the optional C
extensions. The reason for this is that they significantly improve the performance
since some low-level operations that are executed often are much slower in CPython.

If you don't want to install the C bindings, specify the --pure argument to setup.py::

    $ python setup.py --pure install

or if you are installing from pip::

    $ pip install dulwich --global-option="--pure"

Note that you can also specify --global-option in a
`requirements.txt <https://pip.pypa.io/en/stable/reference/pip_install/#requirement-specifiers>`_
file, e.g. like this::

    dulwich --global-option=--pure

Getting started
---------------

Dulwich comes with both a lower-level API and higher-level plumbing ("porcelain").

For example, to use the lower level API to access the commit message of the
last commit::

    >>> from dulwich.repo import Repo
    >>> r = Repo('.')
    >>> r.head()
    '57fbe010446356833a6ad1600059d80b1e731e15'
    >>> c = r[r.head()]
    >>> c
    <Commit 015fc1267258458901a94d228e39f0a378370466>
    >>> c.message
    'Add note about encoding.\n'

And to print it using porcelain::

    >>> from dulwich import porcelain
    >>> porcelain.log('.', max_entries=1)
