protoc

Parse Google Protobuf .proto files and generate output in the specified language. More information: https://developers.google.com/protocol-buffers.

• Generate Python code from a .proto file:

protoc --python_out={{path/to/output_directory}} {{input_file.proto}}

• Generate Java code from a .proto file that imports other .proto files:

protoc --java_out={{path/to/output_directory}} --proto_path={{path/to/import_search_path}} {{input_file.proto}}

• Generate code for multiple languages:

protoc --csharp_out={{path/to/c#_output_directory}} --js_out={{path/to/js_output_directory}} {{input_file.proto}}

• Encode a text-format message into a protocol message from a .proto file:

protoc --encode={{TypeName}} {{input_file.proto}} < {{message.txt}}

• Decode a protocol message into text-format from a .proto file:

protoc --decode={{TypeName}} {{input_file.proto}} < {{message.bin}}

• Decode a protocol message into raw tag/value pairs:

protoc --decode_raw < {{message.bin}}
