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.
Differences with other Python Git libraries
-------------------------------------------
Unlike other Python Git libraries, Dulwich is available as a standalone
package that doesn't depend on git (like GitPython) being installed or any
native code (like pygit2).
This comes at the cost of speed, but makes it easier to deploy in
environments
where git isn't available or where it's important to have a pure Python
implementation.
To improve performance, Dulwich includes optional Rust bindings that can be
used to speed up low-level operations.
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
`_
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
>>> c.message
'Add note about encoding.\n'
And to print it using porcelain::
>>> from dulwich import porcelain
>>> porcelain.log('.', max_entries=1)
