ToyProto

A simple toy implementation of protobuf in C# for C#

Includes

• a simple code generator (ToyProto.Compiler) that generates c# code from a .proto file
• a simple runtime library for c# (ToyProto.Runtime)
• a simple command line tool (ToyProto.Cli) that can be used to compile .proto files and encode or decode messages to and from json

Supported features

• TBD

Usage

Command line tool

• toyproto compile <proto file> -o <output directory>
• toyproto encode <proto file> -i <input json file> -o <output binary file>
• toyproto decode <proto file> -i <input binary file> -o <output json file>

C# generated code

using ToyProto.Runtime;

var person = new Person
{
    Name = "John Doe",
    Age = 30,
    Email = "john.doe@example.com"
};

var bytes = person.Encode();
var decodedPerson = Person.Decode(bytes);
Console.WriteLine(decodedPerson.Name); // Output: John Doe

Development

Prerequisites

• .NET 10.0 SDK or later (NET 6.0 and above might work with change in csproj file)
• Taskfile for building and running the project - see: https://taskfile.dev/docs/installation

Install cli

task install-cli

• now you can run the cli tool with toyproto command
