DevelApp.Minotaur 1.5.0

Minotaur - Advanced Compiler-Compiler Platform

Minotaur is a powerful compiler-compiler platform that revolutionizes grammar development through automated grammar generation, error-driven refinement, and comprehensive language analysis capabilities.

🚀 Key Features

Automated Grammar Generation

• Source Code Analysis: Automatically analyzes existing codebases to extract grammar patterns
• Token Pattern Recognition: Identifies keywords, operators, literals, and structural elements
• Syntax Structure Discovery: Discovers expression precedence, statement types, and control flow patterns
• Error-Driven Refinement: Uses parsing errors to iteratively improve grammar accuracy

Advanced Language Support

• Context-Aware Processing: Leverages advanced context analysis for precise grammar generation
• Multi-Language Support: Handles diverse programming languages and domain-specific languages
• Embedded Grammar Support: Processes languages embedded within other languages (e.g., JavaScript in HTML)
• Grammar File Creation Guide Compliance: Outputs standard-compliant grammar files

Interactive Development Environment

• Command-Line Interface: Comprehensive CLI for grammar generation, validation, and testing
• Real-Time Progress Tracking: Monitor grammar generation progress with detailed metrics
• Quality Assessment: Built-in validation and quality scoring for generated grammars
• Comprehensive Testing: Extensive test suites for grammar validation and refinement

📦 Installation

dotnet add package DevelApp.Minotaur

🔧 Quick Start

StepParser Integration

using Minotaur.Parser;
using Minotaur.Plugins;
using Minotaur.Core;

// Create integration with plugin manager
using var integration = new StepParserIntegration();

// Parse source code to cognitive graph
var sourceCode = "var x = 42;";
var cognitiveGraph = await integration.ParseToCognitiveGraphAsync(sourceCode);

// Edit the graph
cognitiveGraph.AddChild(new TerminalNode("comment", "// Generated"));

// Unparse back to code
var csharpPlugin = integration.PluginManager.GetPlugin("csharp");
var regeneratedCode = await csharpPlugin.UnparseAsync(cognitiveGraph);

Cognitive Graph V2 Support

Minotaur supports both V1 and V2 cognitive graphs:

• V1: Optimized for small to medium projects
• V2: Optimized for large-scale project analysis (CognitiveGraph 1.1.0+)

using Minotaur.Parser;

// Automatic version selection (default)
var autoConfig = new ParserConfiguration
{
    GraphVersion = CognitiveGraphVersion.Auto  // Selects V1 or V2 based on project size
};
using var autoIntegration = new StepParserIntegration(autoConfig);

// Force V2 for large projects
var v2Config = new ParserConfiguration
{
    GraphVersion = CognitiveGraphVersion.V2  // Always use V2
};
using var v2Integration = new StepParserIntegration(v2Config);

// Customize thresholds for auto-detection
var integration = new StepParserIntegration();
integration.SizeAnalyzer.LargeProjectLineThreshold = 5000;  // Lines of code
integration.SizeAnalyzer.LargeProjectCharThreshold = 250000;  // Characters
integration.SizeAnalyzer.LargeProjectFileThreshold = 50;  // Number of files

Plugin System

using Minotaur.Plugins;

// Built-in language plugins
using var pluginManager = new LanguagePluginManager();

// Get plugin by language
var csharpPlugin = pluginManager.GetPlugin("csharp");
var jsPlugin = pluginManager.GetPlugin("javascript");
var pythonPlugin = pluginManager.GetPlugin("python");

// Get plugin by file extension
var plugin = pluginManager.GetPluginByExtension(".cs");

// Generate backend rules for compiler-compiler
var backendRules = await csharpPlugin.GenerateCompilerBackendRulesAsync();
Console.WriteLine($"Generated {backendRules.GenerationRules.Count} rules");

🏗️ Architecture

Core Components

• StepParserIntegration: Integration with DevelApp.StepParser for parsing
• LanguagePluginManager: Runtime plugin discovery and management
• GraphUnparser: Core unparsing engine for code generation
• CognitiveGraphNode: Base node type for cognitive graph representation
• GrammarGenerator: Automated grammar discovery and generation
• SymbolicAnalysisEngine: Advanced code analysis and verification

Architectural Separation

• StepParser: Handles ALL parsing, grammar, and syntax (single source of truth)
• Plugins: Handle unparsing and compiler backend generation ONLY
• Zero-Copy Integration: Seamless data flow between parsing and unparsing

📊 Implementation Status

• ✅ StepParser Integration - Parse source code to cognitive graphs
• ✅ 111 Comprehensive Unit Tests (100% passing)
• ✅ Multi-Language Plugin System - C#, JavaScript, Python, LLVM support
• ✅ Graph Unparsing - Generate code from cognitive graphs
• ✅ Compiler Backend Rules - Generate backend code generation rules
• ✅ Grammar Generation - Automated grammar discovery and generation
• ✅ Symbolic Analysis - Advanced code analysis capabilities
• ✅ Production NuGet Dependencies
