This directory contains the code for the Python brotli module, bro.py tool, and roundtrip tests.

Only Python 2.7+ is supported.

We provide a Makefile to simplify common development commands.

Installation

If you just want to install the latest release of the Python brotli module, we recommend installing from PyPI:

$ pip install brotli

Alternatively, you may install directly from source by running the following command from this directory:

$ make install

If you already have native Brotli installed on your system and want to use this one instead of the vendored sources, you should set the USE_SYSTEM_BROTLI=1 environment variable when building the wheel, like this:

$ USE_SYSTEM_BROTLI=1 pip install brotli --no-binary brotli

Brotli is found via the pkg-config utility. Moreover, you must build all 3 brotlicommon, brotlienc, and brotlidec components. If you're installing brotli from the package manager, you need the development package, like this on Fedora:

$ dnf install brotli brotli-devel

Development

You may run the following commands from this directory:

$ make          # Build the module in-place

$ make test     # Test the module

$ make clean    # Remove all temporary files and build output

If you wish to make the module available while still being able to edit the source files, you can use the setuptools “development mode”:

$ make develop  # Install the module in "development mode"

Code Style

Brotli's code follows the Google Python Style Guide. To automatically format your code, first install YAPF:

$ pip install yapf

Then, to format all files in the project, you can run:

$ make fix      # Automatically format code

See the YAPF usage documentation for more information.
