|
||||
|
||||
IronGo is a native .NET library for parsing Go source code. It provides a complete Abstract Syntax Tree (AST) representation of Go programs with comprehensive support for Go 1.21+ syntax, including generics.
|
||||
|
||||
## Features
|
||||
|
||||
- **Complete Go Parser**: Full support for Go 1.21 syntax including generics
|
||||
- **Strongly-Typed AST**: Native .NET classes for all Go language constructs
|
||||
- **Visitor Pattern**: Both void and generic visitor interfaces for AST traversal
|
||||
- **JSON Serialization**: Export AST to JSON for tooling integration
|
||||
- **Performance Optimized**: Built-in caching and efficient parsing
|
||||
- **Comprehensive Diagnostics**: Detailed error reporting and code analysis
|
||||
- **Cross-Platform**: Works on Windows, Linux, and macOS
|
||||
- **Container-Ready**: Optimized for cloud and containerized environments
|
||||
|
||||
## Installation
|
||||
|
||||
Install IronGo via NuGet:
|
||||
|
||||
```bash
|
||||
dotnet add package IronGo
|
||||
```
|
||||
|
||||
Or via Package Manager Console:
|
||||
|
||||
```powershell
|
||||
Install-Package IronGo
|
||||
```
|
||||
|
||||
## Quick Start
|
||||
|
||||
### Basic Parsing
|
||||
|
||||
```csharp
|
||||
using IronGo;
|
||||
|
||||
// Parse Go source code
|
||||
var source = @"
|
||||
package main
|
||||
|
||||
import ""fmt""
|
||||
|
||||
func main() {
|
||||
fmt.Println(""Hello, World!"")
|
||||
}";
|
||||
|
||||
var ast = IronGoParser.Parse(source);
|
||||
|
||||
// Access AST nodes
|
||||
Console.WriteLine($"Package: {ast.Package.Name}");
|
||||
Console.WriteLine($"Imports: {string.Join(", ", ast.GetImportedPackages())}");
|
||||
Console.WriteLine($"Functions: {ast.GetFunctions().Count()}");
|
||||
```
|
||||
|
||||
### Parsing with Diagnostics
|
||||
|
||||
```csharp
|
||||
// Get detailed parsing information
|
||||
var result = IronGoParser.ParseWithDiagnostics(source);
|
||||
|
||||
Console.WriteLine($"Parse time: {result.Diagnostics.ParseTimeMs}ms");
|
||||
Console.WriteLine($"Token count: {result.Diagnostics.TokenCount}");
|
||||
Console.WriteLine($"Errors: {result.Diagnostics.Errors.Count}");
|
||||
Console.WriteLine($"Warnings: {result.Diagnostics.Warnings.Count}");
|
||||
```
|
||||
|
||||
### Using the Visitor Pattern
|
||||
|
||||
```csharp
|
||||
// Count all function calls in the code
|
||||
public class CallCounter : GoAstWalker
|
||||
{
|
||||
public int CallCount { get; private set; }
|
||||
|
||||
public override void VisitCallExpression(CallExpression node)
|
||||
{
|
||||
CallCount++;
|
||||
base.VisitCallExpression(node);
|
||||
}
|
||||
}
|
||||
|
||||
var counter = new CallCounter();
|
||||
ast.Accept(counter);
|
||||
Console.WriteLine($"Function calls: {counter.CallCount}");
|
||||
```
|
||||
|
||||
### JSON Serialization
|
||||
|
||||
```csharp
|
||||
// Export AST to JSON
|
||||
var json = ast.ToJsonPretty();
|
||||
File.WriteAllText("ast.json", json);
|
||||
|
||||
// Compact JSON for transmission
|
||||
var compactJson = ast.ToJsonCompact();
|
||||
```
|
||||
|
||||
### Advanced Usage
|
||||
|
||||
```csharp
|
||||
// Custom parser options
|
||||
var options = new ParserOptions
|
||||
{
|
||||
EnableCaching = true,
|
||||
RunAnalyzer = true,
|
||||
ContinueOnError = false,
|
||||
ErrorRecoveryMode = ErrorRecoveryMode.Default
|
||||
};
|
||||
|
||||
var parser = new IronGoParser(options);
|
||||
var ast = parser.ParseSource(source);
|
||||
|
||||
// Find specific nodes
|
||||
var mainFunc = ast.FindFunction("main");
|
||||
var allCalls = ast.GetAllCalls();
|
||||
var stringLiterals = ast.GetLiterals(LiteralKind.String);
|
||||
|
||||
// Check imports
|
||||
if (ast.IsPackageImported("fmt"))
|
||||
{
|
||||
Console.WriteLine("fmt package is imported");
|
||||
}
|
||||
```
|
||||
|
||||

// Find specific function by name
|
||||
var mainFunc = ast.FindFunction("main");
|
||||
|
||||
// Get all imported packages
|
||||
var imports = ast.GetImportedPackages();
|
||||
|
||||
// Find all identifiers
|
||||
var identifiers = ast.GetAllIdentifiers();
|
||||
|
||||
// Find all function calls
|
||||
var calls = ast.GetAllCalls();
|
||||
|
||||
// Get literals by type
|
||||
var strings = ast.GetLiterals(LiteralKind.String);
|
||||
var numbers = ast.GetLiterals(LiteralKind.Int);
|
||||
|
||||
// Count total nodes
|
||||
var nodeCount = ast.CountNodes();
|
||||
```
|
||||
|
||||
## Performance
|
||||
|
||||
IronGo includes built-in performance optimizations:
|
||||
|
||||
- **Parser Caching**: Automatically caches parsed results
|
||||
- **Efficient Grammar**: Optimized ANTLR4 grammar
|
||||
- **Minimal Allocations**: Designed to reduce GC pressure
|
||||
|
||||
```csharp
|
||||
// Caching is enabled by default
|
||||
var parser = new IronGoParser();
|
||||
|
||||
// First parse - cache miss
|
||||
var ast1 = parser.ParseSource(source);
|
||||
|
||||
// Second parse - cache hit (very fast)
|
||||
var ast2 = parser.ParseSource(source);
|
||||
|
||||
// Get cache statistics
|
||||
var stats = ParserCache.Default.GetStatistics();
|
||||
Console.WriteLine($"Cache hit rate: {stats.HitRate:P}");
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
IronGo provides comprehensive error handling:
|
||||
|
||||
```csharp
|
||||
// Try parse pattern
|
||||
if (IronGoParser.TryParse(source, out var ast, out var error))
|
||||
{
|
||||
// Success - use ast
|
||||
}
|
||||
else
|
||||
{
|
||||
Console.WriteLine($"Parse error: {error}");
|
||||
}
|
||||
|
||||
// Exception-based parsing
|
||||
try
|
||||
{
|
||||
var ast = IronGoParser.Parse(source);
|
||||
}
|
||||
catch (ParseException ex)
|
||||
{
|
||||
foreach (var error in ex.Errors)
|
||||
{
|
||||
Console.WriteLine($"{error.Line}:{error.Column}: {error.Message}");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Code Analysis
|
||||
|
||||
IronGo includes a built-in code analyzer:
|
||||
|
||||
```csharp
|
||||
var options = new ParserOptions { RunAnalyzer = true };
|
||||
var parser = new IronGoParser(options);
|
||||
var result = parser.ParseSourceWithDiagnostics(source);
|
||||
|
||||
foreach (var warning in result.Diagnostics.Warnings)
|
||||
{
|
||||
Console.WriteLine($"{warning.Level}: {warning.Message} at {warning.Position}");
|
||||
}
|
||||
```
|
||||
|
||||
The analyzer detects:
|
||||
- Empty function bodies
|
||||
- Functions with too many parameters
|
||||
- Duplicate imports
|
||||
- Unused-looking variables (starting with underscore)
|
||||
- Infinite loops without break statements
|
||||
- Empty if-statement clauses
|
||||
|
||||
## Requirements
|
||||
|
||||
- .NET 9.0 or later
|
||||
- No external dependencies beyond ANTLR4 runtime
|
||||
|
||||

## Core Classes
|
||||
|
||||
### IronGoParser
|
||||
|
||||
The main entry point for parsing Go source code.
|
||||
|
||||
#### Static Methods
|
||||
|
||||
```csharp
|
||||
// Parse Go source code from a string
|
||||
public static SourceFile Parse(string source)
|
||||
|
||||
// Parse Go source code from a file
|
||||
public static SourceFile ParseFile(string filePath)
|
||||
|
||||
// Parse Go source code from a stream
|
||||
public static SourceFile Parse(Stream stream)
|
||||
|
||||
// Parse Go source code from a TextReader
|
||||
public static SourceFile Parse(TextReader reader)
|
||||
|
||||
// Parse with diagnostic information
|
||||
public static ParseResult ParseWithDiagnostics(string source)
|
||||
|
||||
// Try to parse, returns success/failure
|
||||
public static bool TryParse(string source, out SourceFile? result, out string? error)
|
||||
```
|
||||
|
||||
#### Instance Methods
|
||||
|
||||
```csharp
|
||||
// Create parser with custom options
|
||||
public IronGoParser(ParserOptions options)
|
||||
|
||||
// Parse source code
|
||||
public SourceFile ParseSource(string source)
|
||||
|
||||
// Parse source file
|
||||
public SourceFile ParseSourceFile(string filePath)
|
||||
|
||||
// Parse from stream
|
||||
public SourceFile ParseStream(Stream stream)
|
||||
|
||||
// Parse from reader
|
||||
public SourceFile ParseReader(TextReader reader)
|
||||
|
||||
// Parse with diagnostics
|
||||
public ParseResult ParseSourceWithDiagnostics(string source)
|
||||
```
|
||||
|
||||
### ParserOptions
|
||||
|
||||
Configuration options for the parser.
|
||||
|
||||
```csharp
|
||||
public class ParserOptions
|
||||
{
|
||||
// Enable caching of parse results (default: true)
|
||||
public bool EnableCaching { get; set; }
|
||||
|
||||
// Custom cache instance (null to use default)
|
||||
public ParserCache? Cache { get; set; }
|
||||
|
||||
// Run AST analyzer for additional diagnostics (default: true)
|
||||
public bool RunAnalyzer { get; set; }
|
||||
|
||||
// Continue parsing even if errors are encountered (default: false)
|
||||
public bool ContinueOnError { get; set; }
|
||||
|
||||
// Error recovery mode (default: Default)
|
||||
public ErrorRecoveryMode ErrorRecoveryMode { get; set; }
|
||||
}
|
||||
```
|
||||
|
||||
### SourceFile
|
||||
|
||||
The root node of the AST representing a complete Go source file.
|
||||
|
||||
```csharp
|
||||
public class SourceFile : IGoNode
|
||||
{
|
||||
// Package declaration
|
||||
public PackageDeclaration? Package { get; }
|
||||
|
||||
// Import declarations
|
||||
public List<ImportDeclaration> Imports { get; }
|
||||
|
||||
// Top-level declarations
|
||||
public List<IDeclaration> Declarations { get; }
|
||||
|
||||
// Position information
|
||||
public Position Start { get; }
|
||||
public Position End { get; }
|
||||
}
|
||||
```
|
||||
|
||||
## AST Node Types
|
||||
|
||||
### Base Interfaces
|
||||
|
||||
```csharp
|
||||
// Base interface for all AST nodes
|
||||
public interface IGoNode
|
||||
{
|
||||
Position Start { get; }
|
||||
Position End { get; }
|
||||
void Accept(IGoAstVisitor visitor);
|
||||
T Accept<T>(IGoAstVisitor<T> visitor);
|
||||
}
|
||||
|
||||
// Base for all expressions
|
||||
public interface IExpression : IGoNode { }
|
||||
|
||||
// Base for all statements
|
||||
public interface IStatement : IGoNode { }
|
||||
|
||||
// Base for all declarations
|
||||
public interface IDeclaration : IGoNode { }
|
||||
|
||||
// Base for all types
|
||||
public interface IType : IGoNode { }
|
||||
```
|
||||
|
||||
### Common Properties
|
||||
|
||||
All AST nodes include:
|
||||
- `Start` - Starting position in source
|
||||
- `End` - Ending position in source
|
||||
- `Accept()` methods for visitor pattern
|
||||
|
||||
## Visitor Pattern
|
||||
|
||||
### IGoAstVisitor
|
||||
|
||||
Void visitor interface for AST traversal.
|
||||
|
||||
```csharp
|
||||
public interface IGoAstVisitor
|
||||
{
|
||||
void VisitSourceFile(SourceFile node);
|
||||
void VisitPackageDeclaration(PackageDeclaration node);
|
||||
void VisitImportDeclaration(ImportDeclaration node);
|
||||
void VisitFunctionDeclaration(FunctionDeclaration node);
|
||||
void VisitMethodDeclaration(MethodDeclaration node);
|
||||
void VisitTypeDeclaration(TypeDeclaration node);
|
||||
// ... methods for all node types
|
||||
}
|
||||
```
|
||||
|
||||
### IGoAstVisitor<T>
|
||||
|
||||
Generic visitor interface that returns values.
|
||||
|
||||
```csharp
|
||||
public interface IGoAstVisitor<T>
|
||||
{
|
||||
T VisitSourceFile(SourceFile node);
|
||||
T VisitPackageDeclaration(PackageDeclaration node);
|
||||
T VisitImportDeclaration(ImportDeclaration node);
|
||||
T VisitFunctionDeclaration(FunctionDeclaration node);
|
||||
T VisitMethodDeclaration(MethodDeclaration node);
|
||||
T VisitTypeDeclaration(TypeDeclaration node);
|
||||
// ... methods for all node types
|
||||
}
|
||||
```
|
||||
|
||||
### Base Implementations
|
||||
|
||||
```csharp
|
||||
// Base visitor that does nothing (for selective overriding)
|
||||
public abstract class GoAstVisitorBase : IGoAstVisitor
|
||||
|
||||
// Walker that visits all child nodes
|
||||
public abstract class GoAstWalker : GoAstVisitorBase
|
||||
|
||||
// Generic visitor base
|
||||
public abstract class GoAstVisitor<T> : IGoAstVisitor<T>
|
||||
```
|
||||
|
||||
## Utility Extensions
|
||||
|
||||
### Finding Nodes

|
||||
|
||||
// Get the parent of a node
|
||||
public static IGoNode? GetParent(this IGoNode node, IGoNode root)
|
||||
|
||||
// Get all nodes at a specific position

|
||||
```json
|
||||
{
|
||||
"Type": "FunctionDeclaration",
|
||||
"Name": "main",
|
||||
"Parameters": [],
|
||||
"ReturnParameters": null,
|
||||
"Body": {
|
||||
"Type": "BlockStatement",
|
||||
"Statements": []
|
||||
},
|
||||
"Start": { "Line": 3, "Column": 1, "Offset": 20 },
|
||||
"End": { "Line": 5, "Column": 2, "Offset": 40 }

## Getting Started
|
||||
|
||||
First, install IronGo via NuGet:
|
||||
|
||||
```bash
|
||||
dotnet add package IronGo
|
||||
```
|
||||
|
||||
Then import the namespace:
|
||||
|
||||
```csharp
|
||||
using IronGo;
|
||||
using IronGo.AST;
|
||||
using IronGo.Utilities;
|
||||
```
|
||||
|
||||
## Parsing Go Code
|
||||
|
||||
### Basic Parsing
|
||||
|
||||
```csharp
|
||||
// Parse from string
|
||||
var source = @"
|
||||
package main
|
||||
|
||||
import ""fmt""
|
||||
|
||||
func main() {
|
||||
fmt.Println(""Hello, World!"")
|
||||
}";
|
||||
|
||||
var ast = IronGoParser.Parse(source);
|
||||
```
|
||||
|
||||
### Parse from File
|
||||
|
||||
```csharp
|
||||
// Parse from file
|
||||
var ast = IronGoParser.ParseFile("path/to/file.go");
|
||||
```
|
||||
|
||||
### Parse with Options
|
||||
|
||||
```csharp
|
||||
// Configure parser options
|
||||
var options = new ParserOptions
|
||||
{
|
||||
EnableCaching = true, // Cache results for repeated parsing
|
||||
RunAnalyzer = true, // Run code analysis
|
||||
ContinueOnError = false // Stop on first error
|
||||
};
|
||||
|
||||
var parser = new IronGoParser(options);
|
||||
var ast = parser.ParseSource(source);
|
||||
```
|
||||
|
||||
## Traversing the AST
|
||||
|
||||
### Using the Visitor Pattern
|
||||
|
||||
Create a custom visitor to traverse the AST:
|
||||
|
||||
```csharp
|
||||
public class FunctionPrinter : GoAstWalker
|
||||
{
|
||||
public override void VisitFunctionDeclaration(FunctionDeclaration node)
|
||||
{
|
||||
Console.WriteLine($"Function: {node.Name}");
|
||||
Console.WriteLine($" Parameters: {node.Parameters.Count}");
|
||||
Console.WriteLine($" Returns: {node.ReturnParameters?.Count ?? 0}");
|
||||
|
||||
// Continue visiting child nodes
|
||||
base.VisitFunctionDeclaration(node);
|
||||
}
|
||||
|
||||
public override void VisitMethodDeclaration(MethodDeclaration node)
|
||||
{
|
||||
Console.WriteLine($"Method: {node.Name}");
|
||||
Console.WriteLine($" Receiver: {node.Receiver.Type}");
|
||||
|
||||
base.VisitMethodDeclaration(node);
|
||||
}
|
||||
}
|
||||
|
||||
// Use the visitor
|
||||
var visitor = new FunctionPrinter();
|
||||
ast.Accept(visitor);
|
||||
```
|
||||
|
||||
### Collecting Information
|
||||
|
||||
Use a generic visitor to collect data:
|
||||
|
||||
```csharp
|
||||
public class ImportCollector : GoAstVisitor<List<string>>
|
||||
{
|
||||
private readonly List<string> _imports = new();
|
||||
|
||||
public override List<string> VisitImportDeclaration(ImportDeclaration node)
|
||||
{
|
||||
foreach (var spec in node.Specs)
|
||||
{
|
||||
_imports.Add(spec.Path);
|
||||
}
|
||||
return _imports;
|
||||
}
|
||||
|
||||
public override List<string> VisitSourceFile(SourceFile node)
|
||||
{
|
||||
foreach (var import in node.Imports)
|
||||
{
|
||||
import.Accept(this);
|
||||
}
|
||||
return _imports;
|
||||
}
|
||||
|
||||
// Default implementation for other nodes
|
||||
protected override List<string> DefaultVisit(IGoNode node) => _imports;
|
||||
}
|
||||
|
||||
var collector = new ImportCollector();
|
||||
var imports = ast.Accept(collector);
|
||||
```
|
||||
|
||||
## Finding Specific Nodes
|
||||
|
||||
### Find Functions
|
||||
|
||||
```csharp
|
||||
// Get all functions
|
||||
var functions = ast.GetFunctions();
|
||||
foreach (var func in functions)
|
||||
{
|
||||
Console.WriteLine($"Function: {func.Name}");
|
||||
}
|
||||
|
||||
// Find specific function
|
||||
var mainFunc = ast.FindFunction("main");
|
||||
if (mainFunc != null)
|
||||
{
|
||||
Console.WriteLine("Found main function");
|
||||
}
|
||||
```
|
||||
|
||||
### Find Types
|
||||
|
||||
```csharp
|
||||
// Get all type declarations
|
||||
var types = ast.GetTypes();
|
||||
foreach (var type in types)
|
||||
{
|
||||
Console.WriteLine($"Type: {type.Name}");
|
||||
|
||||
if (type.Type is StructType structType)
|
||||
{
|
||||
Console.WriteLine($" Struct with {structType.Fields.Count} fields");
|
||||
}
|
||||
else if (type.Type is InterfaceType interfaceType)
|
||||
{
|
||||
Console.WriteLine($" Interface with {interfaceType.Methods.Count} methods");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Find All Nodes of a Type
|
||||
|
||||
```csharp
|
||||
// Find all if statements
|
||||
var ifStatements = ast.FindNodes<IfStatement>();
|
||||
foreach (var ifStmt in ifStatements)
|
||||
{
|
||||
Console.WriteLine("Found if statement");
|
||||
}
|
||||
|
||||
// Find all function calls
|
||||
var calls = ast.GetAllCalls();
|
||||
foreach (var call in calls)
|
||||
{
|
||||
if (call.Function is IdentifierExpression ident)
|
||||
{
|
||||
Console.WriteLine($"Call to: {ident.Name}");
|
||||
}
|
||||
else if (call.Function is SelectorExpression selector)
|
||||
{
|
||||
Console.WriteLine($"Method call: {selector.Member}");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Find Literals
|
||||
|
||||
```csharp
|
||||
// Find all string literals
|
||||
var strings = ast.GetLiterals(LiteralKind.String);
|
||||
foreach (var str in strings)
|
||||
{
|
||||
Console.WriteLine($"String literal: {str.Value}");
|
||||
}
|
||||
|
||||
// Find all numeric literals
|
||||
var numbers = ast.GetLiterals(LiteralKind.Int)
|
||||
.Concat(ast.GetLiterals(LiteralKind.Float));
|
||||
foreach (var num in numbers)
|
||||
{
|
||||
Console.WriteLine($"Number: {num.Value}");
|
||||
}
|
||||
```
|
||||
|
||||
## Code Analysis
|
||||
|
||||
### Analyze Function Complexity
|
||||
|
||||
```csharp
|
||||
public class ComplexityAnalyzer : GoAstWalker
|
||||
{
|
||||
private int _currentComplexity;
|
||||
private readonly Dictionary<string, int> _functionComplexity = new();
|
||||
private string? _currentFunction;
|
||||
|
||||
public override void VisitFunctionDeclaration(FunctionDeclaration node)
|
||||
{
|
||||
_currentFunction = node.Name;
|
||||
_currentComplexity = 1; // Base complexity
|
||||
|
||||
base.VisitFunctionDeclaration(node);
|
||||
|
||||
_functionComplexity[node.Name] = _currentComplexity;
|
||||
_currentFunction = null;
|
||||
}
|
||||
|
||||
public override void VisitIfStatement(IfStatement node)
|
||||
{
|
||||
_currentComplexity++;
|
||||
base.VisitIfStatement(node);
|
||||
}
|
||||
|
||||
public override void VisitForStatement(ForStatement node)
|
||||
{
|
||||
_currentComplexity++;
|
||||
base.VisitForStatement(node);
|
||||
}
|
||||
|
||||
public override void VisitSwitchStatement(SwitchStatement node)
|
||||
{
|
||||
_currentComplexity += node.Cases.Count;
|
||||
base.VisitSwitchStatement(node);
|
||||
}
|
||||
|
||||
public void PrintReport()
|
||||
{
|
||||
Console.WriteLine("Cyclomatic Complexity Report:");
|
||||
foreach (var (func, complexity) in _functionComplexity)
|
||||
{
|
||||
Console.WriteLine($" {func}: {complexity}");
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
var analyzer = new ComplexityAnalyzer();
|
||||
ast.Accept(analyzer);
|
||||
analyzer.PrintReport();
|
||||
```
|
||||
|
||||
### Find Unused Imports
|
||||
|
||||
```csharp
|
||||
public class UnusedImportFinder : GoAstWalker
|
||||
{
|
||||
private readonly HashSet<string> _imports = new();
|
||||
private readonly HashSet<string> _usedPackages = new();
|
||||
|
||||
public override void VisitImportDeclaration(ImportDeclaration node)
|
||||
{
|
||||
foreach (var spec in node.Specs)
|
||||
{
|
||||
var pkgName = spec.Alias ?? Path.GetFileName(spec.Path.Trim('"'));
|
||||
_imports.Add(pkgName);
|
||||
}
|
||||
}
|
||||
|
||||
public override void VisitSelectorExpression(SelectorExpression node)
|
||||
{
|
||||
if (node.Object is IdentifierExpression ident)
|
||||
{
|
||||
_usedPackages.Add(ident.Name);
|
||||
}
|
||||
base.VisitSelectorExpression(node);
|
||||
}
|
||||
|
||||
public IEnumerable<string> GetUnusedImports()
|
||||
{
|
||||
return _imports.Except(_usedPackages);
|
||||
}
|
||||
}
|
||||
|
||||
var finder = new UnusedImportFinder();
|
||||
ast.Accept(finder);
|
||||
var unused = finder.GetUnusedImports();
|
||||
Console.WriteLine($"Unused imports: {string.Join(", ", unused)}");
|
||||
```
|
||||
|
||||
## JSON Export
|
||||
|
||||
### Basic JSON Export
|
||||
|
||||
```csharp
|
||||
// Pretty-printed JSON
|
||||
var prettyJson = ast.ToJsonPretty();
|
||||
File.WriteAllText("ast-pretty.json", prettyJson);
|
||||
|
||||
// Compact JSON
|
||||
var compactJson = ast.ToJsonCompact();
|
||||
File.WriteAllText("ast-compact.json", compactJson);
|
||||
```
|
||||
|
||||
### Selective JSON Export
|
||||
|
||||
```csharp
|
||||
// Export only functions
|
||||
var functions = ast.GetFunctions();
|
||||
var functionsJson = JsonSerializer.Serialize(functions, new JsonSerializerOptions
|
||||
{
|
||||
WriteIndented = true,
|
||||
Converters = { new AstJsonConverter() }
|
||||
});
|
||||
```
|
||||
|
||||
### Custom JSON Processing
|
||||
|
||||
```csharp
|
||||
// Process JSON data
|
||||
var json = ast.ToJson();
|
||||
using var doc = JsonDocument.Parse(json);
|
||||
|
||||
// Navigate JSON
|
||||
var root = doc.RootElement;
|
||||
if (root.GetProperty("Type").GetString() == "SourceFile")
|
||||
{
|
||||
var package = root.GetProperty("Package");
|
||||
var packageName = package.GetProperty("Name").GetString();
|
||||
Console.WriteLine($"Package: {packageName}");
|
||||
}
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
### Try-Parse Pattern
|
||||
|
||||
```csharp
|
||||
if (IronGoParser.TryParse(source, out var ast, out var error))
|
||||
{
|
||||
// Success - process AST
|
||||
Console.WriteLine($"Parsed successfully: {ast.Package?.Name}");
|
||||
}
|
||||
else
|
||||
{
|
||||
// Failure - handle error
|
||||
Console.WriteLine($"Parse error: {error}");
|
||||
}
|
||||
```
|
||||
|
||||
### Exception Handling
|
||||
|
||||
```csharp
|
||||
try
|
||||
{
|
||||
var ast = IronGoParser.Parse(source);
|
||||
}
|
||||
catch (ParseException ex)
|
||||
{
|
||||
Console.WriteLine($"Parse failed with {ex.Errors.Count} errors:");
|
||||
foreach (var error in ex.Errors)
|
||||
{
|
||||
Console.WriteLine($" Line {error.Line}, Col {error.Column}: {error.Message}");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Parsing with Diagnostics
|
||||
|
||||
```csharp
|
||||
var result = IronGoParser.ParseWithDiagnostics(source);
|
||||
|
||||
Console.WriteLine($"Parse time: {result.Diagnostics.ParseTimeMs}ms");
|
||||
Console.WriteLine($"Errors: {result.Diagnostics.Errors.Count}");
|
||||
Console.WriteLine($"Warnings: {result.Diagnostics.Warnings.Count}");
|
||||
|
||||
foreach (var warning in result.Diagnostics.Warnings)
|
||||
{
|
||||
Console.WriteLine($"{warning.Level}: {warning.Message}");
|
||||
}
|
||||
```
|
||||
|
||||
## Performance Optimization
|
||||
|
||||
### Enable Caching
|
||||
|
||||
```csharp
|
||||
// Caching is enabled by default
|
||||
var parser = new IronGoParser();
|
||||
|
||||
// Parse same source multiple times
|
||||
for (int i = 0; i < 100; i++)
|
||||
{
|
||||
var ast = parser.ParseSource(source); // Very fast after first parse
|
||||
}
|
||||
|
||||
// Check cache statistics
|
||||
var stats = ParserCache.Default.GetStatistics();
|
||||
Console.WriteLine($"Cache hits: {stats.TotalHits}");
|
||||
Console.WriteLine($"Hit rate: {stats.HitRate:P}");
|
||||
```
|
||||
|
||||
### Custom Cache Configuration
|
||||
|
||||
```csharp
|
||||
// Create custom cache
|
||||
var cache = new ParserCache(
|
||||
maxCacheSize: 50,
|
||||
cacheExpiration: TimeSpan.FromMinutes(10)
|
||||
);
|
||||
|
||||
var options = new ParserOptions
|
||||
{
|
||||
EnableCaching = true,
|
||||
Cache = cache
|
||||
};
|
||||
|
||||
var parser = new IronGoParser(options);
|
||||
```
|
||||
|
||||
### Disable Caching for Dynamic Code
|
||||
|
||||
```csharp
|
||||
// Disable caching when parsing frequently changing code
|
||||
var options = new ParserOptions
|
||||
{
|
||||
EnableCaching = false
|
||||
};
|
||||
|
||||
var parser = new IronGoParser(options);
|
||||
```
|
||||
|
||||
## Advanced Scenarios
|
||||
|
||||
### Building a Code Formatter
|
||||
|
||||
```csharp
|
||||
public class CodeFormatter : GoAstVisitor<string>
|
||||
{
|
||||
private readonly StringBuilder _output = new();
|
||||
private int _indentLevel = 0;
|
||||
|
||||
private void Write(string text) => _output.Append(text);
|
||||
private void WriteLine(string text = "") => _output.AppendLine(text);
|
||||
private void Indent() => _output.Append(new string(' ', _indentLevel * 4));
|
||||
|
||||
public override string VisitSourceFile(SourceFile node)
|
||||
{
|
||||
if (node.Package != null)
|
||||
{
|
||||
node.Package.Accept(this);
|
||||
WriteLine();
|
||||
}
|
||||
|
||||
foreach (var import in node.Imports)
|
||||
{
|
||||
import.Accept(this);
|
||||
}
|
||||
if (node.Imports.Count > 0) WriteLine();
|
||||
|
||||
foreach (var decl in node.Declarations)
|
||||
{
|
||||
decl.Accept(this);
|
||||
WriteLine();
|
||||
}
|
||||
|
||||
return _output.ToString();
|
||||
}
|
||||
|
||||
public override string VisitPackageDeclaration(PackageDeclaration node)
|
||||
{
|
||||
Write($"package {node.Name}");
|
||||
return "";
|
||||
}
|
||||
|
||||
// ... implement other visit methods
|
||||
}
|
||||
```
|
||||
|
||||
### Finding Dead Code

```csharp
|
||||
public class DeadCodeFinder : GoAstWalker
|
||||
{
|
||||
private readonly HashSet<string> _declaredFunctions = new();
|
||||
private readonly HashSet<string> _calledFunctions = new();
|
||||
|
||||
public override void VisitFunctionDeclaration(FunctionDeclaration node)
|
||||
{
|
||||
_declaredFunctions.Add(node.Name);
|
||||
base.VisitFunctionDeclaration(node);
|
||||
}
|
||||
|
||||
public override void VisitCallExpression(CallExpression node)
|
||||
{
|
||||
if (node.Function is IdentifierExpression ident)
|
||||
{
|
||||
_calledFunctions.Add(ident.Name);
|
||||
}
|
||||
base.VisitCallExpression(node);
|
||||
}
|
||||
|
||||
public IEnumerable<string> GetUnusedFunctions()
|
||||
{
|
||||
// Exclude main and init as they're called by runtime
|
||||
return _declaredFunctions
|
||||
.Except(_calledFunctions)
|
||||
.Where(f => f != "main" && f != "init");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Building a Dependency Graph
|
||||
|
||||
```csharp
|
||||
public class DependencyGraphBuilder : GoAstWalker
|
||||
{
|
||||
public Dictionary<string, HashSet<string>> Dependencies { get; } = new();
|
||||
private string? _currentFunction;
|
||||
|
||||
public override void VisitFunctionDeclaration(FunctionDeclaration node)
|
