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**: **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 `_ 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 >>> c.message 'Add note about encoding.\n' And to print it using porcelain:: >>> from dulwich import porcelain >>> porcelain.log('.', max_entries=1) -------------------------------------------------- commit: 57fbe010446356833a6ad1600059d80b1e731e15 Author: Jelmer Vernooij Date: Sat Apr 29 2017 23:57:34 +0000 Add note about encoding. Further documentation --------------------- The dulwich documentation can be found in docs/ and built by running ``make doc``. It can also be found `on the web `_. Help ---- There is a *#dulwich* IRC channel on the `Freenode `_, and `dulwich-announce `_ and `dulwich-discuss `_ mailing lists. Contributing ------------ For a full list of contributors, see the git logs or `AUTHORS `_. If you'd like to contribute to Dulwich, see the `CONTRIBUTING `_ file and `list of open issues `_. Supported versions of Python ---------------------------- At the moment, Dulwich supports (and is tested on) CPython 3.5, 3.6, 3.7, 3.8 and Pypy. The latest release series to support Python 2.x was the 0.19 series. See the 0.19 branch in the Dulwich git repository.

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**: **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 `_ 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 >>> c.message 'Add note about encoding.\n' And to print it using porcelain:: >>> from dulwich import porcelain >>> porcelain.log('.', max_entries=1) -------------------------------------------------- commit: 57fbe010446356833a6ad1600059d80b1e731e15 Author: Jelmer Vernooij Date: Sat Apr 29 2017 23:57:34 +0000 Add note about encoding. Further documentation --------------------- The dulwich documentation can be found in docs/ and built by running ``make doc``. It can also be found `on the web `_. Help ---- There is a *#dulwich* IRC channel on the `Freenode `_, and `dulwich-announce `_ and `dulwich-discuss `_ mailing lists. Contributing ------------ For a full list of contributors, see the git logs or `AUTHORS `_. If you'd like to contribute to Dulwich, see the `CONTRIBUTING `_ file and `list of open issues `_. Supported versions of Python ---------------------------- At the moment, Dulwich supports (and is tested on) CPython 3.5, 3.6, 3.7, 3.8 and Pypy. The latest release series to support Python 2.x was the 0.19 series. See the 0.19 branch in the Dulwich git repository.
