Protobuf Processor

Purpose

Compiles Protocol Buffer (.proto) files to generated source code using protoc.

How It Works

Files matching configured extensions in the proto/ directory are compiled using the Protocol Buffer compiler. Output is written to out/protobuf/:

proto/hello.proto  →  out/protobuf/hello.pb.cc

The --proto_path is automatically set to the parent directory of each input file.

Source Files

• Input: proto/**/*.proto
• Output: out/protobuf/ with .pb.cc extension

Configuration

[processor.protobuf]
protoc_bin = "protoc"                     # Protoc binary (default: "protoc")
src_extensions = [".proto"]                   # File extensions to process
output_dir = "out/protobuf"              # Output directory (default: "out/protobuf")
dep_inputs = []                         # Additional files that trigger rebuilds

Batch support

Each input file is processed individually, producing its own output file.
