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.

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

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

By default, Dulwich' setup.py will attempt to build and install the optional Rust
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 Rust bindings, specify the --pure argument to setup.py::

    $ python setup.py --pure install

or if you are installing from pip::

    $ pip install --no-binary dulwich dulwich --config-settings "--build-option=--pure"

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

    dulwich --config-settings "--build-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)
