+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Nette PHP Generator is a library for programmatically generating PHP code - classes, functions, namespaces, and complete PHP files. It supports all modern PHP features including property hooks (PHP 8.4), enums, attributes, asymmetric visibility, and more.
+
+The library provides both a builder API for constructing PHP structures and extraction capabilities for loading existing PHP code.
+
+## Essential Commands
+
+### Testing
+```bash
+# Run all tests
+composer run tester
+# OR
+vendor/bin/tester tests -s
+
+# Run specific test file
+vendor/bin/tester tests/PhpGenerator/ClassType.phpt -s
+
+# Run tests in specific directory
+vendor/bin/tester tests/PhpGenerator/ -s
+```
+
+### Static Analysis
+```bash
+# Run PHPStan analysis
+composer run phpstan
+# OR
+vendor/bin/phpstan analyse
+```
+
+### Code Style
+The project follows Nette Coding Standard with configuration in `ncs.php`. Uses tabs for indentation and braces on next line for functions/methods.
+
+## Architecture
+
+### Core Components
+
+**PhpFile** (`PhpFile.php`)
+- Top-level container representing a complete PHP file
+- Manages namespaces, strict_types declaration, and file-level comments
+- Entry point: `PhpFile::add()` for adding namespaces/classes/functions
+
+**PhpNamespace** (`PhpNamespace.php`)
+- Represents a namespace with use statements and contained classes/functions
+- Handles type resolution and name simplification based on use statements
+- Methods: `addClass()`, `addInterface()`, `addTrait()`, `addEnum()`, `addFunction()`
+
+**ClassLike** (`ClassLike.php`)
+- Abstract base for class-like structures (classes, interfaces, traits, enums)
+- Provides common functionality for attributes and comments
+- Extended by ClassType, InterfaceType, TraitType, EnumType
+
+**ClassType** (`ClassType.php`)
+- Represents class definitions with full feature support
+- Composes traits for properties, methods, constants, and trait usage
+- Supports final, abstract, readonly modifiers, extends, and implements
+
+**Method** (`Method.php`) & **GlobalFunction** (`GlobalFunction.php`)
+- Method represents class/interface/trait methods
+- GlobalFunction represents standalone functions
+- Both use FunctionLike trait for parameters, return types, and body
+
+**Property** (`Property.php`)
+- Represents class properties with type hints, visibility, hooks
+- Supports PHP 8.4 property hooks (get/set) via PropertyHook class
+- Supports asymmetric visibility (different get/set visibility)
+
+**Printer** (`Printer.php`) & **PsrPrinter** (`PsrPrinter.php`)
+- Printer: Generates code following Nette Coding Standard (tabs, braces on next line)
+- PsrPrinter: Generates PSR-2/PSR-12/PER compliant code
+- Configurable via properties: `$wrapLength`, `$indentation`, `$linesBetweenMethods`, etc.
+- Handles type resolution when printing within namespace context
+
+**Factory** (`Factory.php`) & **Extractor** (`Extractor.php`)
+- Factory: Creates PhpGenerator objects from existing classes/functions
+- Extractor: Low-level parser integration (requires nikic/php-parser)
+- Enable loading existing code: `ClassType::from()`, `PhpFile::fromCode()`
+
+**Dumper** (`Dumper.php`)
+- Converts PHP values to code representation
+- Used internally for default values, but also available for standalone use
+- Better output than `var_export()`
+
+### Trait Organization (`Traits/`)
+
+Shared functionality is implemented via traits for composition:
+
+- **FunctionLike**: Parameters, return types, body management for functions/methods
+- **PropertyLike**: Core property functionality (type, value, visibility)
+- **AttributeAware**: Attribute support for all elements
+- **CommentAware**: Doc comment management
+- **VisibilityAware**: Visibility modifiers (public/protected/private)
+- **ConstantsAware**: Class constant management
+- **MethodsAware**: Method collection management
+- **PropertiesAware**: Property collection management
+- **TraitsAware**: Trait usage management
+
+This trait-based architecture allows ClassType to compose all necessary features while keeping concerns separated.
+
+### Type System
+
+**Type** (`Type.php`)
+- Constants for native types (String, Int, Array, etc.)
+- Helper methods for union/intersection/nullable types
+- Used throughout for type hints and return types
+
+**Literal** (`Literal.php`)
+- Represents raw PHP code that should not be escaped
+- Used for default values, constants, expressions
+- Supports placeholders for value injection (see Placeholders section below)
+- `Literal::new()` helper for creating object instantiation literals
+
+### Test Structure
+
+Tests use Nette Tester with `.phpt` extension:
+- Located in `tests/PhpGenerator/`
+- Mirror source file organization
+- Use `test()` function for test cases (defined in `bootstrap.php`)
+- Use `testException()` for exception testing
+- Helper functions: `same()`, `sameFile()` for assertions
+
+Example test pattern:
+```php
+test('description of what is being tested', function () {
+    $class = new ClassType('Demo');
+    // ... test code
+    Assert::same($expected, (string) $class);
+});
+```
+
+## Important Features
+
+### Placeholders in Function Bodies
+
+The library supports special placeholders for inserting values into method/function bodies:
+
+- **`?`** - Simple placeholder for single values (strings, numbers, arrays)
+  ```php
+  $function->addBody('return substr(?, ?);', [$str, $num]);
+  // Generates: return substr('any string', 3);
+  ```
+
+- **`...?`** - Variadic placeholder (unpacks arrays as separate arguments)
+  ```php
+  $function->setBody('myfunc(...?);', [[1, 2, 3]]);
+  // Generates: myfunc(1, 2, 3);
+  ```
+
+- **`...?:`** - Named parameters placeholder for PHP 8+
+  ```php
+  $function->setBody('myfunc(...?:);', [['foo' => 1, 'bar' => true]]);
+  // Generates: myfunc(foo: 1, bar: true);
+  ```
+
+- **`\?`** - Escaped placeholder (literal question mark)
+  ```php
+  $function->addBody('return $a \? 10 : ?;', [$num]);
+  // Generates: return $a ? 10 : 3;
+  ```
+
+### Printer Configuration
+
+Both `Printer` and `PsrPrinter` can be customized by extending and overriding public properties:
+
+```php
+class MyPrinter extends Nette\PhpGenerator\Printer
+{
+    public int $wrapLength = 120;              // line length for wrapping
+    public string $indentation = "\t";          // indentation character
+    public int $linesBetweenProperties = 0;     // blank lines between properties
+    public int $linesBetweenMethods = 2;        // blank lines between methods
+    public int $linesBetweenUseTypes = 0;       // blank lines between use statement groups
+    public bool $bracesOnNextLine = true;       // opening brace position for functions/methods
+    public bool $singleParameterOnOneLine = false; // single parameter formatting
+    public bool $omitEmptyNamespaces = true;    // omit empty namespaces
+    public string $returnTypeColon = ': ';      // separator before return type
+}
+```
+
+**Note:** `Printer` uses Nette Coding Standard (tabs, braces on next line), while `PsrPrinter` follows PSR-2/PSR-12/PER (spaces, braces on same line).
+
+### Property Hooks (PHP 8.4)
+
+Property hooks allow defining get/set operations directly on properties:
+
+```php
+$prop = $class->addProperty('firstName')->setType('string');
+$prop->addHook('set', 'strtolower($value)')  // Arrow function style
+    ->addParameter('value')->setType('string');
+$prop->addHook('get')                         // Block style
+    ->setBody('return ucfirst($this->firstName);');
+```
+
+Property hooks can be marked as `abstract` or `final` using `setAbstract()` / `setFinal()`.
+
+### Asymmetric Visibility (PHP 8.4)
+
+Properties can have different visibility for reading vs writing:
+
+```php
+// Using setVisibility() with two parameters
+$class->addProperty('name')
+    ->setVisibility('public', 'private'); // public get, private set
+
+// Using modifier methods with 'get' or 'set' mode
+$class->addProperty('id')
+    ->setProtected('set'); // protected set, public get (default)
+```
+
+Generates: `public private(set) string $name;`
+
+### ClassManipulator
+
+The `ClassManipulator` class provides advanced class manipulation:
+
+- **`inheritMethod($name)`** - Copies method from parent/interface for overriding
+- **`inheritProperty($name)`** - Copies property from parent class
+- **`implement($interface)`** - Automatically implements all methods/properties from interface/abstract class
+
+```php
+$manipulator = new Nette\PhpGenerator\ClassManipulator($class);
+$manipulator->implement(SomeInterface::class);
+// Now $class contains stub implementations of all interface methods
+```
+
+### Arrow Functions
+
+While `Closure` represents anonymous functions, you can generate arrow functions using the printer:
+
+```php
+$closure = new Nette\PhpGenerator\Closure;
+$closure->setBody('$a + $b');  // Note: arrow function body without 'return'
+$closure->addParameter('a');
+$closure->addParameter('b');
+
+echo (new Nette\PhpGenerator\Printer)->printArrowFunction($closure);
+// Generates: fn($a, $b) => $a + $b
+```
+
+### Cloning Members
+
+Methods, properties, and constants can be cloned under a different name:
+
+```php
+$methodCount = $class->getMethod('count');
+$methodRecount = $methodCount->cloneWithName('recount');
+$class->addMember($methodRecount);
+```
+
+## Key Patterns
+
+### Builder Pattern
+All classes use fluent interface - methods return `$this`/`static` for chaining:
+```php
+$class->setFinal()
+    ->setExtends(ParentClass::class)
+    ->addImplement(Countable::class);
+```
+
+### Type Resolution
+When a class is part of a namespace, types are automatically resolved:
+- Fully qualified names → simplified based on use statements
+- Can be disabled: `$printer->setTypeResolving(false)`
+- Use `$namespace->simplifyType()` for manual resolution
+
+### Code Generation Flow
+1. Create PhpFile
+2. Add namespace(s)
+3. Add classes/interfaces/traits/enums/functions to namespace
+4. Add members (properties/methods/constants) to classes
+5. Convert to string or use Printer explicitly
+
+### Validation
+Classes validate themselves before printing via `validate()` method. Throws `Nette\InvalidStateException` for invalid states (e.g., abstract and final simultaneously).
+
+### Cloning
+All major classes implement `__clone()` to deep-clone contained objects (methods, properties, etc.).
+
+## Common Tasks
+
+### Adding New Features
+1. Check if feature needs new class or extends existing (e.g., PropertyHook for property hooks)
+2. Add tests first in `tests/PhpGenerator/`
+3. Update Printer to generate correct syntax
+4. Update Factory/Extractor if feature should be loadable from existing code
+5. Consider PsrPrinter compatibility
+
+### Updating for New PHP Versions
+1. Add support to builder classes (e.g., new method/property)
+2. Update Printer with syntax generation
+3. Update Extractor to parse the feature (via php-parser)
+4. Add comprehensive tests including edge cases
+5. Update README.md with examples
+
+### Test Expectations
+- Test files may have corresponding `.expect` files with expected output
+- Use `sameFile()` helper to compare against expectation files
+- This keeps test files clean and makes output changes visible in diffs
+
+## Important Notes & Limitations
+
+### Loading from Existing Code
+- **Requires `nikic/php-parser`** to load method/function bodies with `withBodies: true` / `withBody: true`
+- Without php-parser, bodies are empty but signatures are complete
+- Single-line comments outside method bodies are ignored when loading (library has no API for them)
+- Use `nikic/php-parser` directly if you need to manipulate global code or individual statements
+
+### PhpFile Restrictions
+- **No global code allowed** - PhpFile can only contain namespaces, classes, functions
+- Cannot add arbitrary code like `echo 'hello'` outside functions/classes
+- Use `setStrictTypes()` for `declare(strict_types=1)` declaration
+
+### Exception Handling
+- Adding duplicate members (same name) throws `Nette\InvalidStateException`
+- Use `addMember($member, overwrite: true)` to replace existing members
+- Invalid class states (e.g., abstract + final) detected by `validate()` method
+
+### Removal Methods
+- `removeProperty($name)`, `removeConstant($name)`, `removeMethod($name)`, `removeParameter($name)`
+- Available on respective container classes
+
+### Compatibility
+- **PhpGenerator 4.1+** supports PHP 8.0 to 8.4
+- **PhpGenerator 4.2** (current) compatible with PHP 8.1 to 8.5
+- Check composer.json for exact version requirements
