hob 0.3.3

Introduction

Hob is a multi-language code generator for the Opera Scope Protocol. It generates code from Google Protocol Buffer files (.proto), which describes the services, messages, commands and events.

The Scope Protocol is an RPC system used in the Opera web browser. This allows external and embedded clients to debug, inspect or perform other operations on any running Opera instance.

Hob consists of the following components:

• The hob command line tool which is used to generate code and other output formats.

• A library for working with Google Protocol Buffer definitions. It can read .proto files and has classes and functions for working with protobuf elements.

• Support for third party extensions which can add additional commands.

Dependencies
