Edit Brotli BUILD.gn to make fuzzers optional Embedders of Brotli from chromium's dependencies (ex: PDFium) do not need the fuzzers and usually do not include libfuzzer when standalone, hence this CL uses the build_with_chromium argument for these embedders so that the fuzzers do not need to be built and the additional dependency does not need to be pulled for the standalone repo.

Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression.
The specification of the Brotli Compressed Data Format is defined in RFC 7932.
Brotli is open-sourced under the MIT License, see the LICENSE file.
Please note: brotli is a “stream” format; it does not contain meta-information, like checksums or uncompressed data length. It is possible to modify “raw” ranges of the compressed stream and the decoder will not notice that.
In most Linux distributions, installing brotli is just a matter of using the package management system. For example in Debian-based distributions: apt install brotli will install brotli. On MacOS, you can use Homebrew: brew install brotli.
Of course you can also build brotli from sources.
You can download and install brotli using the vcpkg dependency manager:
git clone https://github.com/Microsoft/vcpkg.git cd vcpkg ./bootstrap-vcpkg.sh ./vcpkg integrate install ./vcpkg install brotli
The brotli port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please create an issue or pull request on the vcpkg repository.
See Bazel
The basic commands to build and install brotli are:
$ mkdir out && cd out $ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=./installed .. $ cmake --build . --config Release --target install
You can use other CMake configuration.
To install the latest release of the Python module, run the following:
$ pip install brotli
To install the tip-of-the-tree version, run:
$ pip install --upgrade git+https://github.com/google/brotli
See the Python readme for more details on installing from source, development, and testing.
