Haya 0.0.3

haya-net

Haya automates the generating of documentation and diagrams for a .NET codebase. It uses attributes to define concepts like Responsibilities and Collaborators. The tool uses these concepts to generate CRC descriptions and C4 Level 1 diagrams.

See the examples folder of the attribute annotations and the generated CRC.

Note: This currently only works for C# codebases.

This is not meant to be a replacement for good documentation practices, but rather a tool to help you get started, or at the least have a minimum level for a new joiner to start exploring the codebase.

Getting Started

1. Install the Haya CLI tool

dotnet tool install --global Haya.Tool

2. Add the Haya attributes package to your project.

dotnet add package Haya

3. Run the Haya CLI tool

haya --help

Usage

1. Add the Haya attributes to your codebase. See Attributes docs for more information.

using Haya;
[assembly:Meta(AppName = "CheckoutApi", Description = "Handles processing payment for a shopping cart", System = "HayaEcomm")]

namespace Example;

[Responsibility(Description = "Handles order processing")]
public class CreditCardPaymentUsecase
{ }

[Collaborator(AppName = "Checkout",
    Relationship = Relationship.Internal,
    Direction = Direction.Upstream,
    System = "WebShop",
    Description = "Handles cart checkout for a customer",
    DataDescription = "Request payment")]
public class PaymentsController
{ }

Running the Haya CLI tool will generate a CRC document and a C4 Level 1 diagram.

haya crc --format md --c4 ./Example.sln
