Compile "proto" Files with "protoc"

Install "protoc"

1.1 Compile the .proto File into Python Format

protoc --python_out=. addressbook.proto

1.2 Compile the .proto File into Descriptor

Embedding All Dependencies and .proto Files in One File

To ensure that all dependencies and .proto files are embedded into a single file, use the following protoc command:

protoc --include_source_info --include_imports --descriptor_set_out=descriptor.pb $(PROTO_FILES)
  • ... indicates any additional options you were using previously.
  • $(PROTO_FILES) represents the list of all the .proto files.

By executing the above command, you'll obtain a single .pb file containing all the compiled .proto files along with their dependencies. This approach is highly convenient to avoid frequent file modifications.


Understanding the --include_imports Option

The --include_imports option in protoc (Protocol Buffers Compiler) ensures that all import statements in a .proto file are included in the output when generating a descriptor set file. This is especially beneficial when you aim to encompass all dependencies of a .proto file in the descriptor set, rather than just the file itself.

Note: protoc can accept multiple ".proto" files simultaneously as arguments. All the files provided as arguments will be incorporated into the generated file descriptor. This feature is particularly advantageous for embedding all dependencies of a .proto file in the descriptor set.
