Repository Layout and Build

This page is the operational map of the repo: where things live, how the solution is put together, and what the build actually does.

If you are onboarding as a contributor, this is the page that turns "I know what GridForge is" into "I know where to work and which command to run."

Solution Shape

The solution currently contains three projects:

Project Path Purpose
GridForge src/GridForge/GridForge.csproj Main deterministic voxel-grid library
GridForge.Tests tests/GridForge.Tests/GridForge.Tests.csproj xUnit validation suite
GridForge.Benchmarks tests/GridForge.Benchmarks/GridForge.Benchmarks.csproj BenchmarkDotNet performance and allocation benchmarks

The root solution file is GridForge.slnx.

Repository Layout

Path What it contains
src/GridForge Library source, package metadata, XML docs generation, and NuGet packaging configuration
src/GridForge/Configuration Grid creation inputs and snapped bounds identity
src/GridForge/Grids Core grid model, managers, node types, and pooling
src/GridForge/Spatial Shared indices, occupants, partitions, directions, and awareness types
src/GridForge/Blockers Bounds-based obstacle application built on tracer coverage
src/GridForge/Utility Tracing and logging support
tests/GridForge.Tests Unit tests organized by subsystem
tests/GridForge.Benchmarks Focused perf and allocation scenarios
.github/workflows CI automation
.assets/scripts Release-oriented PowerShell helpers
GridForge.wiki GitHub wiki content used as the deeper documentation companion

The solution also exposes a small set of root-level "solution items" such as .editorconfig, README.md, AGENTS.md, LICENSE, and coverlet.runsettings.

Main Library Build Facts

The library project in src/GridForge/GridForge.csproj establishes a few important build behaviors:

  • language version is C# 11
  • target frameworks are netstandard2.1 and net8.0
  • ImplicitUsings is disabled
  • Nullable is disabled
  • XML documentation files are generated
  • deterministic and CI build flags are enabled
  • GeneratePackageOnBuild is enabled

That last item is easy to miss: building the library also produces NuGet artifacts.

Package And Dependency Notes

The main library currently depends on:

  • FixedMathSharp 2.1.1
  • SwiftCollections 3.0.0
  • MemoryPack 1.21.4
  • System.Text.Json 10.0.5 for the netstandard2.1 target only

Packaging also includes the root README.md, LICENSE, NOTICE, COPYRIGHT, and icon.png.

Versioning Behavior

The project is wired to consume GitVersion environment variables when they are available.

In practice that means:

  • CI can stamp semantic version, assembly version, and informational version automatically
  • local builds still work without GitVersion and fall back to version 0.0.0

That fallback is intentional and keeps local iteration simple.

What dotnet build Produces

When you build src/GridForge/GridForge.csproj, expect:

  • compiled library outputs under src/GridForge/bin/<Configuration>/<TargetFramework>/
  • XML documentation alongside the assembly
  • .nupkg and .snupkg package artifacts because package generation is enabled on build

If you are only expecting a DLL and a testable build, this packaging behavior can look surprising the first time you notice it.

Validation Project Facts

GridForge.Tests

The test project:

  • targets net8.0
  • is marked as a test project and not packable
  • references the main library project directly
  • uses xUnit v3 plus the Visual Studio runner and console runner
  • includes coverlet.collector
  • points to coverlet.runsettings

The runsettings currently exclude generated MemoryPack files from coverage collection so coverage numbers are less noisy.

GridForge.Benchmarks

The benchmark project:

  • targets net8.0
  • is an executable
  • references the main library project directly
  • uses BenchmarkDotNet
  • is optimized for benchmark runs

This project is where allocation-sensitive or throughput-sensitive changes should be checked.

Common Build Commands

The usual local flow is:

dotnet restore GridForge.slnx
dotnet build GridForge.slnx --configuration Debug
dotnet test GridForge.slnx --configuration Debug --no-build

When you specifically want release-like library artifacts:

dotnet build src/GridForge/GridForge.csproj --configuration Release

Because packaging is enabled on build, this also emits the package artifacts.

CI Expectations

The current CI workflow lives in .github/workflows/dotnet.yml.

At a high level it:

  • runs on ubuntu-latest and windows-latest
  • triggers on pushes except dependabot/**, gh-pages, and version tags like v*
  • triggers on pull requests targeting main
  • installs .NET 8
  • installs and executes GitVersion
  • restores dependencies
  • builds the solution in Debug
  • runs the test suite in Debug

This is a useful sanity check when deciding whether a change is likely to be cross-platform safe.

Release Helper Script

.assets/scripts/set-version-and-build.ps1 is the repo helper for version-aware release builds.

Its flow is:

  1. locate the solution root
  2. ensure GitVersion environment variables are present
  3. build the project in the requested configuration
  4. walk each Release target-framework output folder
  5. zip each framework output into a versioned archive

That makes it the practical handoff script for release packaging, not just a convenience wrapper around dotnet build.

Build And Repo Pitfalls

  • Forgetting that the library builds for two target frameworks
  • Forgetting that build also creates NuGet packages
  • Assuming CI only validates on one operating system
  • Editing files under bin, obj, or TestResults instead of the source that produces them
  • Treating the benchmark project as optional when changing pooling, tracing, or registration behavior
