Protocol Buffers - Google's data interchange formatCopyright 2008 Google Inc. Buffers (a.k.a., protobuf) are Google's language-neutral,platform-neutral, extensible mechanism for serializing structured data. Youcan find protobuf's documentation on the Google Developers site.This README file contains protobuf installation instructions. To installprotobuf, you need to install the protocol compiler (used to compile .protofiles) and the protobuf runtime for your chosen programming language.Protocol Compiler InstallationThe protocol compiler is written in C++. If you are using C++, please followthe C++ Installation Instructions to install protoc alongwith the C++ runtime.For non-C++ users, the simplest way to install the protocol compiler is todownload a pre-built binary from our release page: the downloads section of each release, you can find pre-built binaries inzip packages: protoc-$VERSION-$PLATFORM.zip. It contains the protoc binaryas well as a set of standard .proto files distributed along with protobuf.If you are looking for an old version that is not available in the releasepage, check out the maven repo here: pre-built binaries are only provided for released versions. If you wantto use the github main version at HEAD, or you need to modify protobuf code,or you are using C++, it's recommended to build your own protoc binary fromsource.If you would like to build protoc binary from source, see the C++ InstallationInstructions.Protobuf Runtime InstallationProtobuf supports several different programming languages. For each programminglanguage, you can find instructions in the corresponding source directory abouthow to install protobuf runtime for that specific language:LanguageSourceC++ (include C++ runtime and protoc)srcJavajavaPythonpythonObjective-CobjectivecC#csharpRubyrubyGoprotocolbuffers/protobuf-goPHPphpDartdart-lang/protobufQuick StartThe best way to learn how to use protobuf is to follow the tutorials in ourdeveloper guide: you want to learn from code examples, take a look at the examples in theexamples directory.DocumentationThe complete documentation for Protocol Buffers is available via theweb at:
