Universal C&C Launcher Development Team

Welcome to the GeneralsHub development team! This guide will get you up to speed with our project, architecture, development workflow, and contribution standards.

1️⃣ Project Overview

GeneralsHub is a cross-platform desktop application for managing, launching, and customizing Command & Conquer: Generals / Zero Hour.
It solves the problem of ecosystem fragmentation by detecting game installations, managing multiple versions, and integrating mods/maps/patches from multiple sources into isolated, conflict-free workspaces.

The architecture is modular and service-driven, with a three-tier content pipeline:

Content Orchestrator – Coordinates all content providers.
Content Providers – Handle specific sources (GitHub, ModDB, CNC Labs, local files).
Pipeline Components – Specialized discoverers, resolvers, and deliverers.

Key Features

🎮 Game Profile Management: Custom configurations combining base games with mods and patches
🔍 Content Discovery: Automated discovery from GitHub, ModDB, CNC Labs, and local sources
📁 Isolated Workspaces: Each profile runs in its own workspace to prevent conflicts
🌐 Cross-Platform: Native Windows and Linux support

2️⃣ Workflow & Contribution Process

We follow a GitHub-first workflow:

1. Find or Create an Issue

All work starts with a GitHub Issue.
If you have an idea, create an issue and label it appropriately.

2. Branching Strategy

Create a branch from main using the format:

bash

feature/<short-description>
fix/<short-description>
refactor/<short-description>

3. Code Standards

StyleCop is enforced — your code must pass style checks before merging.
Follow C# naming conventions and keep methods/classes small and focused.
XML documentation is required for all public classes, methods, and properties.

4. Testing Requirements

All new code must have xUnit tests.
Tests live in the GenHub.Tests project, mirroring the folder structure of the main code.
Run tests locally before pushing.

5. Pull Request Process

Open a PR linked to the issue.
GitHub Actions will run:
- Build on Windows & Linux
- Run all tests
- StyleCop analysis
PRs failing checks will be rejected automatically.

6. Code Review

At least one approval from a reviewer is required before merging.
Be open to feedback and iterate quickly.

3️⃣ Repository Structure

Here's the high-level directory layout:

GenHub/           → Main Avalonia UI application
GenHub.Core/      → Core business logic, models, interfaces (platform-agnostic)
GenHub.Windows/   → Windows-specific implementations
GenHub.Linux/     → Linux-specific implementations
GenHub.Tests/     → Unit & integration tests (xUnit)

Inside GenHub.Core

Interfaces/ – Contracts for services (e.g., IGameInstallationDetector, IContentProvider)
Models/ – Data models, enums, DTOs
Features/ – Grouped by domain (Content, GameProfiles, Manifest, Workspace, etc.)
Services/ – Implementations of interfaces
Validation/ – Validators for installations, versions, and files

Inside GenHub.Tests

Mirrors the structure of GenHub.Core and GenHub
Each service/class has a corresponding test file
Uses xUnit + Moq for mocking dependencies

4️⃣ Infrastructure & Services

GeneralsHub is built around Dependency Injection and Service Modules:

AppServices.cs – Registers all core services
ContentDeliveryModule.cs – Registers content pipeline components
GameDetectionModule.cs – Registers installation/version detection
WorkspaceModule.cs – Registers workspace strategies
ValidationModule.cs – Registers validators

Key Service Categories

Detection Services – Find game installations & versions
Manifest Services – Create & manage content manifests
Content Pipeline – Orchestrator, providers, discoverers, resolvers, deliverers
Workspace Services – Prepare isolated game directories
Launching Services – Start games with correct configs
Storage Services – Manage content storage (CAS system)

5️⃣ Coding Standards

We enforce StyleCop rules:

PascalCase for public members
camelCase for private fields (with _ prefix)
XML documentation for all public APIs
No unused usings
Consistent spacing & brace style

Example Code Style

csharp

/// <summary>
/// Detects all game installations on the system.
/// </summary>
public interface IGameInstallationDetectionOrchestrator
{
    /// <summary>
    /// Asynchronously detects all available game installations.
    /// </summary>
    /// <returns>A read-only list of detected game installations.</returns>
    Task<IReadOnlyList<GameInstallation>> DetectAllInstallationsAsync();
}

6️⃣ Testing Guidelines

All code changes must have unit tests in GenHub.Tests:

Basic Test Structure

csharp

[Fact]
public void ShouldDetectSteamInstallation()
{
    // Arrange
    var detector = new SteamInstallationDetector();

    // Act
    var result = detector.Detect();

    // Assert
    Assert.NotNull(result);
}

Testing with Dependencies

For services with dependencies, use Moq to mock interfaces:

csharp

[Fact]
public async Task ShouldDownloadContent()
{
    // Arrange
    var mockFileService = new Mock<IFileService>();
    var downloadService = new DownloadService(mockFileService.Object);

    // Act
    var result = await downloadService.DownloadAsync("http://test.com/file.zip");

    // Assert
    Assert.True(result.Success);
    mockFileService.Verify(x => x.SaveAsync(It.IsAny<string>(), It.IsAny<byte[]>()), Times.Once);
}

7️⃣ Getting Started

Prerequisites

.NET 8 SDK or later
Visual Studio 2022 / JetBrains Rider / VS Code
Git for version control

Setup Instructions

Clone the repository

bash

git clone https://github.com/community-outpost/GenHub.git
cd GenHub

Restore dependencies
bash
```
dotnet restore
```
Build the solution
bash
```
dotnet build
```
Run tests
bash
```
dotnet test
```
Run the application
- Set GenHub as the startup project
- Press F5 or run: dotnet run --project GenHub

Development Environment

Windows: Full development and testing capabilities
Linux: Full development and testing capabilities
macOS: Limited support (builds but not officially tested)

8️⃣ Communication & Collaboration

We use multiple channels for different types of communication:

Discord Server

Our primary communication hub with dedicated channels:

#general – General discussion and introductions
#development – Technical discussions and questions
#feedback – User feedback and feature requests
#issues – Issue tracking and bug reports
#pull-requests – PR discussions and reviews
#releases – Release announcements and updates

GitHub

Issues – Task tracking, bug reports, feature requests
Pull Requests – Code review and discussion
Discussions – Architecture decisions and long-form topics
Wiki – Extended documentation and guides

Best Practices

Ask questions early – Don't struggle alone, we're here to help
Use the right channel – Keep discussions organized
Search before asking – Check existing issues and discussions
Be respectful and constructive – We're all here to build something great

9️⃣ Architecture Deep Dive

For a comprehensive understanding of the system architecture, see our Architecture Documentation.

Key Architectural Concepts

Three-Tier Content Pipeline
- Tier 1: Content Orchestrator (system-wide coordination)
- Tier 2: Content Providers (source-specific orchestration)
- Tier 3: Pipeline Components (specialized operations)
Five Architectural Pillars
- GameInstallation: Physical game detection
- GameVersion: Executable identification
- GameManifest: Declarative content packaging
- GameProfile: User configuration
- Workspace: Isolated execution environment
Service-Oriented Design
- Dependency injection throughout
- Interface-based contracts
- Platform abstraction layers
- Modular service registration
