+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Overview
+
+Parser Reflection is a **deprecated** PHP library (deprecated in favor of [BetterReflection](https://github.com/Roave/BetterReflection)) that extends PHP's internal reflection classes using nikic/PHP-Parser for static analysis. It reflects PHP code without loading classes into memory by parsing source files into an AST.
+
+Requires PHP >=8.2. Namespace: `Go\ParserReflection\`.
+
+## Commands
+
+```bash
+# Install dependencies (slow locally — see note below)
+composer install --prefer-source --no-interaction
+
+# Run tests (~6 seconds, ~10,500 tests)
+vendor/bin/phpunit
+
+# Run a single test file
+vendor/bin/phpunit tests/ReflectionClassTest.php
+
+# Run a specific test method
+vendor/bin/phpunit --filter testMethodName
+
+# Static analysis (~5 seconds, 18 known existing errors are normal)
+vendor/bin/phpstan analyse src --no-progress
+
+# Code quality check (dry-run only — don't auto-apply)
+vendor/bin/rector --dry-run
+```
+
+> **Note on `composer install` locally**: due to GitHub API rate limits, use `--prefer-source` and set a long timeout: `composer config --global process-timeout 2000`. In CI, standard `composer install` works fine with GitHub tokens.
+
+## Architecture
+
+### Request flow
+
+When you call `new ReflectionClass('SomeClass')`:
+1. `ReflectionClass` asks `ReflectionEngine` for the class's AST node
+2. `ReflectionEngine` uses the registered `LocatorInterface` to find the file
+3. The file is parsed by PHP-Parser into an AST
+4. Two node visitors run: `NameResolver` (resolves FQCNs) and `RootNamespaceNormalizer` (normalizes global namespace)
+5. The resulting `ClassLike` AST node is stored in `ReflectionEngine::$parsedFiles` (in-memory LRU cache)
+6. The node is wrapped in the appropriate reflection class
+
+### Key components
+
+- **`ReflectionEngine`** (`src/ReflectionEngine.php`) — static class; central hub. Owns the PHP-Parser instance, AST cache, and locator. Entry points: `parseFile()`, `parseClass()`, `parseClassMethod()`, etc.
+- **`LocatorInterface`** / **`ComposerLocator`** — pluggable class file finder. `ComposerLocator` delegates to Composer's classmap/autoloader. `bootstrap.php` auto-registers `ComposerLocator` on load.
+- **Reflection classes** (`src/Reflection*.php`) — each extends its PHP internal counterpart (e.g. `ReflectionClass extends \ReflectionClass`) and holds an AST node. Methods that require a live object (e.g. `invoke()`) trigger actual class loading and fall back to native reflection.
+- **Traits** (`src/Traits/`) — shared logic extracted to avoid duplication:
+  - `ReflectionClassLikeTrait` — used by `ReflectionClass`; implements most class inspection methods against the AST
+  - `ReflectionFunctionLikeTrait` — shared by `ReflectionMethod` and `ReflectionFunction`
+  - `InitializationTrait` — lazy initialization of AST node from engine
+  - `InternalPropertiesEmulationTrait` — makes `var_dump`/serialization look like native reflection
+  - `AttributeResolverTrait` — resolves PHP 8 attributes from AST nodes
+- **Resolvers** (`src/Resolver/`) — `NodeExpressionResolver` evaluates constant expressions in the AST (used for default values, constants). `TypeExpressionResolver` resolves type AST nodes into reflection type objects.
+- **`ReflectionFile` / `ReflectionFileNamespace`** — library-specific (not in native PHP reflection). Allow reflecting arbitrary PHP files and iterating their namespaces, classes, functions without knowing class names in advance.
+
+### Test structure
+
+Tests in `tests/` mirror the reflection class names (e.g. `ReflectionClassTest.php`). PHP version-specific stub files in `tests/Stub/` (e.g. `FileWithClasses84.php`) contain the PHP code being reflected. Tests extend `AbstractTestCase` which sets up the `ReflectionEngine` with a `ComposerLocator`.
+
+### CI
+
+GitHub Actions (`.github/workflows/phpunit.yml`) runs PHPUnit on PHP 8.2, 8.3, 8.4 with both lowest and highest dependency versions.

Subject: [PATCH 03/15] chore: fix all PHPStan level 5 errors

- Fix type mismatches in NodeExpressionResolver, TypeExpressionResolver,
  ReflectionClassLikeTrait, and ReflectionFunctionLikeTrait
- Remove unused constructor parameter from TypeExpressionResolver
- Fix ClassLike property access with proper instanceof narrowing in ReflectionClass
- Fix array key types and dead code in ReflectionClassLikeTrait
- Add ignoreErrors for unset.possiblyHookedProperty in final classes
  ReflectionFunction and ReflectionMethod (false positive: final classes
  cannot have subclasses with hooks)
- Replace array_reduce with foreach to fix callable type inference

Subject: [PATCH 04/15] chore: fix PHPStan level 6 errors

Add missing PHPDoc type annotations for generic types and iterable value
types across all source files:
- Add @extends ReflectionClass<object> and ReflectionAttribute<object>
- Type all array<K, V> properties and return types
- Add ReflectionClass<object> generics to method return types

Subject: [PATCH 05/15] chore: fix PHPStan level 7 errors

Fix actual type errors surfaced at level 7:
- Fix PathResolver::realpath() return type to reflect recursive return
- Add instanceof guards before accessing Arg::$value and Const_::$value
- Fix ReflectionAttribute::getTypeNode() union type check
- Add false-check around fetchReflectionClass() calls in NodeExpressionResolver
- Fix constants property key type (int|string instead of string)
- Add @return class-string and non-empty-string overrides for getName/getShortName
- Fix getNamespaceName() method.notFound by guarding against ReflectionAttribute

Subject: [PATCH 06/15] chore: fix PHPStan level 8 errors

Fix null-safety and type-safety issues:
- Add null guards for ReflectionEngine::$locator before use
- Fix NodeTraverser::traverse() call with null-safe ?? []
- Add null checks before TypeExpressionResolver::process() calls
- Add null check for Identifier::toString() in findClassLikeNodeByClassName
- Fix offsetAccess.notFound in PathResolver by guarding string|null
- Add null guards around method_exists() calls in NodeExpressionResolver
- Fix $constOrEnumCaseNode null assignment in ReflectionClassConstant

Subject: [PATCH 07/15] chore: fix PHPStan level 9 errors

Fix mixed-type propagation from PhpParser Node::getAttribute() calls:
- Use hasAttribute() + explicit casts for getStartLine/getEndLine/getFileName
- Add instanceof Name guards before calling toString() on getAttribute() results
- Fix array key types by guarding with is_string()/is_int() checks
- Fix StaticVariablesCollector context type to match NodeExpressionResolver
- Fix sprintf with mixed value in ReflectionClassConstant
- Fix TypeExpressionResolver return types with explicit typed returns

Subject: [PATCH 08/15] chore: fix PHPStan level 10 errors

Fix remaining mixed-type and type-safety issues at level 10:
- Add abstract getNodeForAttributes() to AttributeResolverTrait for typed node access
- Fix CallableLocator return type with explicit string|false narrowing
- Fix ReflectionClassConstant::gettype() usage with proper array key narrowing
- Fix NodeExpressionResolver getAttribute() mixed results with type guards
- Fix ReflectionFileNamespace getAttribute() calls with proper int|false returns
- Fix ReflectionUnionType array_search with proper array type
- Filter Stringable objects in ReflectionClassLikeTrait::__toString() buildString

Subject: [PATCH 09/15] fix: resolve self/parent type hints to actual class
 names

Native PHP reflection resolves 'self' to the declaring class FQCN and
'parent' to the parent class FQCN in type hints. The parser-based
TypeExpressionResolver was returning the literals 'self'/'parent'.

- Add optional $selfClassName/$parentClassName to TypeExpressionResolver
- Add getDeclaringClassNameForTypes()/getParentClassNameForTypes() hook
  methods to ReflectionFunctionLikeTrait (default null for functions)
- Override both hooks in ReflectionMethod with the declaring class names
- Pass declaring class context when constructing TypeExpressionResolver
  in ReflectionParameter, ReflectionProperty, ReflectionClassConstant
- Keep 'static' unresolved (preserved as-is by native PHP reflection)

Fixes all 4 previously failing PHPUnit tests.

Subject: [PATCH 12/15] fix: address PR review comments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Remove class_alias() from resolveAsClassString() and resolveAttributeClassName()
  (global side-effect; class names from AST are semantically class-strings by
  construction). Add ignoreErrors entries for these two known PHPStan limitations.
- Convert silent continue statements to explicit ReflectionException throws in
  NodeExpressionResolver (variadic placeholders, non-scalar named arg keys,
  non-scalar array keys) and ReflectionFileNamespace (define() with unsupported args).
- Fix PathResolver::realpath() unsafe $path[1] indexing — use regex-based Windows
  drive letter detection (matches PR suggestion).
- Fix ReflectionProperty::setValue() to check isStatic() before validating object arg,
  consistent with native ReflectionProperty behavior.
- Remove always-true PHP_VERSION_ID >= 80400 guards in ReflectionProperty::getModifiers()
  since composer.json now requires PHP >= 8.4.

Subject: [PATCH 14/15] fix: resolve self/parent types only on PHP 8.5+ to
 match native behavior

PHP 8.5 changed ReflectionNamedType::getName() to return the actual FQCN
for 'self' and 'parent' type hints, whereas PHP 8.4 and earlier return
the keywords as-is. Gate the resolution behind PHP_VERSION_ID >= 80500
so the library mirrors native reflection behavior on all supported versions.

Fixes CI failures on PHP 8.4 builds.

Subject: [PATCH 15/15] fix(property): restore single-arg setValue() for static
 properties

setValue(\$value) with one argument is the canonical PHP 8.4+ way to set
a static property value. The previous implementation silently forwarded
null as the value because \$value defaulted to null.

Also update CLAUDE.md to reflect the actual PHP >=8.4 requirement.

 Parser Reflection is a **deprecated** PHP library (deprecated in favor of [BetterReflection](https://github.com/Roave/BetterReflection)) that extends PHP's internal reflection classes using nikic/PHP-Parser for static analysis. It reflects PHP code without loading classes into memory by parsing source files into an AST.
