Sharpitect 0.2.4

Sharpitect

Sharpitect generates C4 architecture diagrams from annotated C# codebases. It analyzes your code using Roslyn and builds a declaration graph that can be queried and visualized.

Features

• Code Analysis - Extracts declarations (classes, interfaces, methods, properties, etc.) and their relationships using Roslyn
• Declaration Graph - Builds a queryable graph of code elements with containment and reference relationships
• Graph Search - Search for declarations by name with multiple match modes and kind filters
• SQLite Persistence - Persist and query the declaration graph from a SQLite database
• C4 Model Mapping - Maps code elements to C4 architecture model levels

C4 Conventions

Sharpitect maps C# constructs to C4 model elements following these conventions:

Systems

• Systems are solutions (.sln files)

Containers

• Containers are projects that generate an executable

Components

• Components cannot be nested, but they can be grouped by namespaces or projects
• Components may be projects, namespaces, or groups
• Use the [Component] attribute to mark types as C4 components

Code

• Code elements are automatically extracted class diagrams including classes, interfaces, methods, and properties

Usage

Analyzing a Solution

using Sharpitect.Analysis.Analyzers;
using Sharpitect.Analysis.Persistence;

// Create repository
var repository = new SqliteGraphRepository("architecture.db");
await repository.InitializeAsync();

// Analyze solution
var analyzer = new GraphSolutionAnalyzer(repository);
await analyzer.AnalyzeAsync("path/to/solution.sln");

Searching the Graph

using Sharpitect.Analysis.Graph;
using Sharpitect.Analysis.Search;

// Create search service with in-memory source
var graph = new DeclarationGraph();
var source = new InMemoryGraphSource(graph);
var searchService = new GraphSearchService(source);

// Search for classes containing "Service"
var query = new SearchQuery
{
    SearchText = "Service",
    MatchMode = SearchMatchMode.Contains,
    KindFilter = [DeclarationKind.Class]
};

var results = await searchService.SearchAsync(query);

Search Options

• SearchText - The text to search for in Name and FullyQualifiedName
• MatchMode - How to match: Contains, StartsWith, EndsWith, or Exact
• KindFilter - Optional filter by declaration kind (Class, Interface, Method, etc.)
• CaseSensitive - Whether the search is case-sensitive (default: false)

Project Structure

• Sharpitect.Tool - Command-line tool entry point
• Sharpitect.Analysis - Analysis engine with graph, persistence, search, and analyzers
• Sharpitect.Attributes - Attributes for annotating code (targets .NET Framework 4.8 for broad compatibility)
• Sharpitect.Analysis.Test - Unit tests

Installation

Installing as a Global Tool

dotnet tool install -g Sharpitect.Tool

If the sharpitect command is not found after installation, you need to add the .NET tools directory to your PATH. Add the following line to your shell configuration file (~/.bashrc, ~/.bash_profile, or ~/.zshrc):

export PATH="$PATH:$HOME/.dotnet/tools"

Then reload your shell configuration:

source ~/.bashrc  # or ~/.bash_profile or ~/.zshrc

Alternatively, you can run this one-liner to add it permanently:

echo 'export PATH="$PATH:$HOME/.dotnet/tools"' >> ~/.bashrc && source ~/.bashrc

Building

dotnet build Sharpitect.sln

Testing

dotnet test Sharpitect.sln
