Nodepp Protobuf

A minimal, zero-dependency Protocol Buffers implementation for Nodepp.
Parse and serialize protobuf messages in ~100 lines of C++. No code generation. No protoc. No dependencies.

Built on Nodepp's ptr_t, any_t, and array_t. Zero-copy. Thread-safe. 2KB.

🚀 Quick Start

#include <nodepp/nodepp.h>
#include <nodepp/json.h>
#include <protobuf/protobuf.h>

using namespace nodepp;

void onMain() {

    /* Build a protobuf message
    protobuf_t msg ({
        uchar_16(42),
        string_t("hola"),
        uchar_32(12345) ,
        uchar_64(12345)
    });
    */

    // Build a protobuf message
    protobuf_t msg;
    msg.push( uchar_16(42)     );  // field 0: varint
    msg.push( string_t("hola") );  // field 1: length-delimited
    msg.push( uchar_32(12345)  );  // field 2: 32-bit
    msg.push( uchar_64(12345)  );  // field 3: 64-bit

    // Serialize
    auto data = protobuf::format( msg );
    console::log( "encoded:", data.size(), "bytes" );

    // Parse
    auto parsed = protobuf::parse( data );
    console::log( "field 0:", parsed[0].as<uchar_16>() );
    console::log( "field 1:", parsed[1].as<string_t>() );
    console::log( "field 2:", parsed[2].as<uchar_32>() );
    console::log( "field 3:", parsed[3].as<uchar_64>() );

    // stringify
    console::log( json::stringify( parsed ) );
