+# PHP Static Scanner Instrumentalization
+
+Static security scanners usually are not clever enough to detect our injection of parameters in the Nextcloud source code.
+
+This instrumentalization script loops over a given directory and instrumentalizes the source code by directly injecting
+a `$_GET` on code related to the Nextcloud appframework. So the original code would look like:
+
+```php
+<?php
+use OCP\AppFramework\Controller;
+
+class Foo extends Controller {
+    public function list($index) {
+        // Logic of the code
+    }
+}
+```
+
+`$index` in the function `list` here would automatically be read from `$_GET`, to make the static scanners aware of that
+the resulting code would look like:
+
+```php
+<?php
+use OCP\AppFramework\Controller;
+
+class Foo extends Controller {
+    public function list($index) {
+        $index = $_GET['index'];
+        // Logic of the code
+    }
+}
+```

+Version 3.0.3-dev
+-----------------
+
+Nothing yet.
+
+Version 3.0.2 (2016-12-06)
+--------------------------
+
+### Fixed
+
+* Fixed name resolution of nullable types.
+* Fixed pretty-printing of nullable types.
+
+Version 3.0.1 (2016-12-01)
+--------------------------
+
+### Fixed
+
+* Fixed handling of nested `list()`s: If the nested list was unkeyed, it was directly included in
+  the list items. If it was keyed, it was wrapped in `ArrayItem`. Now nested `List_` nodes are
+  always wrapped in `ArrayItem`s.
+
+Version 3.0.0 (2016-11-30)
+--------------------------
+
+### Added
+
+* Added support for dumping node positions in the NodeDumper through the `dumpPositions` option.
+* Added error recovery support for `$`, `new`, `Foo::`.
+
+Version 3.0.0-beta2 (2016-10-29)
+--------------------------------
+
+This release primarily improves our support for error recovery.
+
+### Added
+
+* Added `Node::setDocComment()` method.
+* Added `Error::getMessageWithColumnInfo()` method.
+* Added support for recovery from lexer errors.
+* Added support for recovering from "special" errors (i.e. non-syntax parse errors).
+* Added precise location information for lexer errors.
+* Added `ErrorHandler` interface, and `ErrorHandler\Throwing` and `ErrorHandler\Collecting` as
+  specific implementations. These provide a general mechanism for handling error recovery.
+* Added optional `ErrorHandler` argument to `Parser::parse()`, `Lexer::startLexing()` and
+  `NameResolver::__construct()`.
+* The `NameResolver` now adds a `namespacedName` attribute on name nodes that cannot be statically
+  resolved (unqualified unaliased function or constant names in namespaces).
+  
+### Fixed
+
+* Fixed attribute assignment for `GroupUse` prefix and variables in interpolated strings.
+
+### Changed
+
+* The constants on `NameTraverserInterface` have been moved into the `NameTraverser` class.
+* Due to the error handling changes, the `Parser` interface and `Lexer` API have changed.
+* The emulative lexer now directly postprocesses tokens, instead of using `~__EMU__~` sequences.
+  This changes the protected API of the lexer.
+* The `Name::slice()` method now returns `null` for empty slices, previously `new Name([])` was
+  used. `Name::concat()` now also supports concatenation with `null`.
+
+### Removed
+
+* Removed `Name::append()` and `Name::prepend()`. These mutable methods have been superseded by
+  the immutable `Name::concat()`.
+* Removed `Error::getRawLine()` and `Error::setRawLine()`. These methods have been superseded by
+  `Error::getStartLine()` and `Error::setStartLine()`.
+* Removed support for node cloning in the `NodeTraverser`.
+* Removed `$separator` argument from `Name::toString()`.
+* Removed `throw_on_error` parser option and `Parser::getErrors()` method. Use the `ErrorHandler`
+  mechanism instead.
+
+Version 3.0.0-beta1 (2016-09-16)
+--------------------------------
+
+### Added
+
+* [7.1] Function/method and parameter builders now support PHP 7.1 type hints (void, iterable and
+  nullable types).
+* Nodes and Comments now implement `JsonSerializable`. The node kind is stored in a `nodeType`
+  property.
+* The `InlineHTML` node now has an `hasLeadingNewline` attribute, that specifies whether the
+  preceding closing tag contained a newline. The pretty printer honors this attribute.
+* Partial parsing of `$obj->` (with missing property name) is now supported in error recovery mode.
+* The error recovery mode is now exposed in the `php-parse` script through the `--with-recovery`
+  or `-r` flags.
+
+The following changes are also part of PHP-Parser 2.1.1:
+
+* The PHP 7 parser will now generate a parse error for `$var =& new Obj` assignments.
+* Comments on free-standing code blocks will now be retained as comments on the first statement in
+  the code block.
+
+Version 3.0.0-alpha1 (2016-07-25)
+---------------------------------
+
+### Added
+
+* [7.1] Added support for `void` and `iterable` types. These will now be represented as strings
+  (instead of `Name` instances) similar to other builtin types.
+* [7.1] Added support for class constant visibility. The `ClassConst` node now has a `flags` subnode
+  holding the visibility modifier, as well as `isPublic()`, `isProtected()` and `isPrivate()`
+  methods. The constructor changed to accept the additional subnode.
+* [7.1] Added support for nullable types. These are represented using a new `NullableType` node
+  with a single `type` subnode.
+* [7.1] Added support for short array destructuring syntax. This means that `Array` nodes may now
+  appear as the left-hand-side of assignments and foreach value targets. Additionally the array
+  items may now contain `null` values if elements are skipped.
+* [7.1] Added support for keys in list() destructuring. The `List` subnode `vars` has been renamed
+  to `items` and now contains `ArrayItem`s instead of plain variables.
+* [7.1] Added support for multi-catch. The `Catch` subnode `type` has been renamed to `types` and
+  is now an array of `Name`s.
+* `Name::slice()` now supports lengths and negative offsets. This brings it in line with
+  `array_slice()` functionality.
+
+### Changed
+
+Due to PHP 7.1 support additions described above, the node structure changed as follows:
+
+* `void` and `iterable` types are now stored as strings if the PHP 7 parser is used.
+* The `ClassConst` constructor changed to accept an additional `flags` subnode.
+* The `Array` subnode `items` may now contain `null` elements (destructuring).
+* The `List` subnode `vars` has been renamed to `items` and now contains `ArrayItem`s instead of
+  plain variables.
+* The `Catch` subnode `type` has been renamed to `types` and is now an array of `Name`s.
+
+Additionally the following changes were made:
+
+* The `type` subnode on `Class`, `ClassMethod` and `Property` has been renamed to `flags`. The
+  `type` subnode has retained for backwards compatibility and is populated to the same value as
+  `flags`. However, writes to `type` will not update `flags`.
+* The `TryCatch` subnode `finallyStmts` has been replaced with a `finally` subnode that holds an
+  explicit `Finally` node. This allows for more accurate attribute assignment.
+* The `Trait` constructor now has the same form as the `Class` and `Interface` constructors: It
+  takes an array of subnodes. Unlike classes/interfaces, traits can only have a `stmts` subnode.
+* The `NodeDumper` now prints class/method/property/constant modifiers, as well as the include and
+  use type in a textual representation, instead of only showing the number.
+* All methods on `PrettyPrinter\Standard` are now protected. Previoulsy most of them were public.
+
+### Removed
+
+* Removed support for running on PHP 5.4. It is however still possible to parse PHP 5.2-5.4 code
+  while running on a newer version.
+* The deprecated `Comment::setLine()` and `Comment::setText()` methods have been removed.
+* The deprecated `Name::set()`, `Name::setFirst()` and `Name::setLast()` methods have been removed.
+
+Version 2.1.1 (2016-09-16)
+--------------------------
+
+### Changed
+
+* The pretty printer will now escape all control characters in the range `\x00-\x1F` inside double
+  quoted strings. If no special escape sequence is available, an octal escape will be used.
+* The quality of the error recovery has been improved. In particular unterminated expressions should
+  be handled more gracefully.
+* The PHP 7 parser will now generate a parse error for `$var =& new Obj` assignments.
+* Comments on free-standing code blocks will no be retained as comments on the first statement in
+  the code block.
+
+Version 2.1.0 (2016-04-19)
+--------------------------
+
+### Fixed
+
+* Properly support `B""` strings (with uppercase `B`) in a number of places.
+* Fixed reformatting of indented parts in a certain non-standard comment style.
+
+### Added
+
+* Added `dumpComments` option to node dumper, to enable dumping of comments associated with nodes.
+* Added `Stmt\Nop` node, that is used to collect comments located at the end of a block or at the
+  end of a file (without a following node with which they could otherwise be associated).
+* Added `kind` attribute to `Expr\Exit` to distinguish between `exit` and `die`.
+* Added `kind` attribute to `Scalar\LNumber` to distinguish between decimal, binary, octal and
+  hexadecimal numbers.
+* Added `kind` attribtue to `Expr\Array` to distinguish between `array()` and `[]`.
+* Added `kind` attribute to `Scalar\String` and `Scalar\Encapsed` to distinguish between
+  single-quoted, double-quoted, heredoc and nowdoc string.
+* Added `docLabel` attribute to `Scalar\String` and `Scalar\Encapsed`, if it is a heredoc or
+  nowdoc string.
+* Added start file offset information to `Comment` nodes.
+* Added `setReturnType()` method to function and method builders.
+* Added `-h` and `--help` options to `php-parse` script.
+
+### Changed
+
+* Invalid octal literals now throw a parse error in PHP 7 mode.
+* The pretty printer takes all the new attributes mentioned in the previous section into account.
+* The protected `AbstractPrettyPrinter::pComments()` method no longer returns a trailing newline.
+* The bundled autoloader supports library files being stored in a different directory than
+  `PhpParser` for easier downstream distribution.
+
+### Deprecated
+
+* The `Comment::setLine()` and `Comment::setText()` methods have been deprecated. Construct new
+  objects instead.
+
+### Removed
+
+* The internal (but public) method `Scalar\LNumber::parse()` has been removed. A non-internal
+  `LNumber::fromString()` method has been added instead.
+
+Version 2.0.1 (2016-02-28)
+--------------------------
+
+### Fixed
+
+* `declare() {}` and `declare();` are not semantically equivalent and will now result in different
+  ASTs. The format case will have an empty `stmts` array, while the latter will set `stmts` to
+  `null`.
+* Magic constants are now supported as semi-reserved keywords.
+* A shebang line like `#!/usr/bin/env php` is now allowed at the start of a namespaced file.
+  Previously this generated an exception.
+* The `prettyPrintFile()` method will not strip a trailing `?>` from the raw data that follows a
+  `__halt_compiler()` statement.
+* The `prettyPrintFile()` method will not strip an opening `<?php` if the file starts with a
+  comment followed by InlineHTML.
+
+Version 2.0.0 (2015-12-04)
+--------------------------
+
+### Changed
+
+* String parts of encapsed strings are now represented using `Scalar\EncapsStringPart` nodes.
+  Previously raw strings were used. This affects the `parts` child of `Scalar\Encaps` and
+  `Expr\ShellExec`. The change has been done to allow assignment of attributes to encapsed string
+  parts.
+
+Version 2.0.0-beta1 (2015-10-21)
+--------------------------------
+
+### Fixed
+
+* Fixed issue with too many newlines being stripped at the end of heredoc/nowdoc strings in some
+  cases. (#227)
+
+### Changed
+
+* Update group use support to be in line with recent PHP 7.0 builds.
+* Renamed `php-parse.php` to `php-parse` and registered it as a composer bin.
+* Use composer PSR-4 autoloader instead of custom autoloader.
+* Specify phpunit as a dev dependency.
+
+### Added
+
+* Added `shortArraySyntax` option to pretty printer, to print all arrays using short syntax.
+
+Version 2.0.0-alpha1 (2015-07-14)
+---------------------------------
+
+A more detailed description of backwards incompatible changes can be found in the
+[upgrading guide](UPGRADE-2.0.md).
+
+### Removed
+
+* Removed support for running on PHP 5.3. It is however still possible to parse PHP 5.2 and PHP 5.3
+  code while running on a newer version.
+* Removed legacy class name aliases. This includes the old non-namespaced class names and the old
+  names for classes that were renamed for PHP 7 compatibility.
+* Removed support for legacy node format. All nodes must have a `getSubNodeNames()` method now.
+
+### Added
+
+* Added support for remaining PHP 7 features that were not present in 1.x:
+  * Group use declarations. These are represented using `Stmt\GroupUse` nodes. Furthermore a `type`
+    attribute was added to `Stmt\UseUse` to handle mixed group use declarations.
+  * Uniform variable syntax.
+  * Generalized yield operator.
+  * Scalar type declarations. These are presented using `'bool'`, `'int'`, `'float'` and `'string'`
+    as the type. The PHP 5 parser also accepts these, however they'll be `Name` instances there.
+  * Unicode escape sequences.
+* Added `PhpParser\ParserFactory` class, which should be used to create parser instances.
+* Added `Name::concat()` which concatenates two names.
+* Added `Name->slice()` which takes a subslice of a name.
+
+### Changed
+
+* `PhpParser\Parser` is now an interface, implemented by `Parser\Php5`, `Parser\Php7` and
+  `Parser\Multiple`. The `Multiple` parser will try multiple parsers, until one succeeds.
+* Token constants are now defined on `PhpParser\Parser\Tokens` rather than `PhpParser\Parser`.
+* The `Name->set()`, `Name->append()`, `Name->prepend()` and `Name->setFirst()` methods are
+  deprecated in favor of `Name::concat()` and `Name->slice()`.
+* The `NodeTraverser` no longer clones nodes by default. The old behavior can be restored by
+  passing `true` to the constructor.
+* The constructor for `Scalar` nodes no longer has a default value. E.g. `new LNumber()` should now
+  be written as `new LNumber(0)`.

+PHP Parser
+==========
+
+[![Build Status](https://travis-ci.org/nikic/PHP-Parser.svg?branch=master)](https://travis-ci.org/nikic/PHP-Parser) [![Coverage Status](https://coveralls.io/repos/github/nikic/PHP-Parser/badge.svg?branch=master)](https://coveralls.io/github/nikic/PHP-Parser?branch=master)
+
+This is a PHP 5.2 to PHP 7.1 parser written in PHP. Its purpose is to simplify static code analysis and
+manipulation.
+
+[**Documentation for version 3.x**][doc_master] (stable; for running on PHP >= 5.5; for parsing PHP 5.2 to PHP 7.1).
+
+[Documentation for version 2.x][doc_2_x] (stable; for running on PHP >= 5.4; for parsing PHP 5.2 to PHP 7.0).
+
+[Documentation for version 1.x][doc_1_x] (unsupported; for running on PHP >= 5.3; for parsing PHP 5.2 to PHP 5.6).
+
+In a Nutshell
+-------------
+
+The parser turns PHP source code into an abstract syntax tree. For example, if you pass the following code into the
+parser:
+
+```php
+<?php
+echo 'Hi', 'World';
+hello\world('foo', 'bar' . 'baz');
+```
+
+You'll get a syntax tree looking roughly like this:
+
+```php
+array(
+    0: Stmt_Echo(
+        exprs: array(
+            0: Scalar_String(
+                value: Hi
+            )
+            1: Scalar_String(
+                value: World
+            )
+        )
+    )
+    1: Expr_FuncCall(
+        name: Name(
+            parts: array(
+                0: hello
+                1: world
+            )
+        )
+        args: array(
+            0: Arg(
+                value: Scalar_String(
+                    value: foo
+                )
+                byRef: false
+            )
+            1: Arg(
+                value: Expr_Concat(
+                    left: Scalar_String(
+                        value: bar
+                    )
+                    right: Scalar_String(
+                        value: baz
+                    )
+                )
+                byRef: false
+            )
+        )
+    )
+)
+```
+
+You can then work with this syntax tree, for example to statically analyze the code (e.g. to find
+programming errors or security issues).
+
+Additionally, you can convert a syntax tree back to PHP code. This allows you to do code preprocessing
+(like automatedly porting code to older PHP versions).

+Upgrading from PHP-Parser 0.9 to 1.0
+====================================
+
+### PHP version requirements
+
+PHP-Parser now requires PHP 5.3 or newer to run. It is however still possible to *parse* PHP 5.2 source code, while
+running on a newer version.
+
+### Move to namespaced names
+
+The library has been moved to use namespaces with the `PhpParser` vendor prefix. However, the old names using
+underscores are still available as aliases, as such most code should continue running on the new version without
+further changes.
+
+Old (still works, but discouraged):
+
+```php
+$parser = new \PHPParser_Parser(new \PHPParser_Lexer_Emulative);
+$prettyPrinter = new \PHPParser_PrettyPrinter_Default;
+```
+
+New:
+
+```php
+$parser = new \PhpParser\Parser(new PhpParser\Lexer\Emulative);
+$prettyPrinter = new \PhpParser\PrettyPrinter\Standard;
+```
+
+Note that the `PHPParser` prefix was changed to `PhpParser`. While PHP class names are technically case-insensitive,
+the autoloader will not be able to load `PHPParser\Parser` or other case variants.
+
+Due to conflicts with reserved keywords, some class names now end with an underscore, e.g. `PHPParser_Node_Stmt_Class`
+is now `PhpParser\Node\Stmt\Class_`. (But as usual, the old name is still available.)
+
+### Changes to `Node::getType()`
+
+The `Node::getType()` method continues to return names using underscores instead of namespace separators and also does
+not contain the trailing underscore that may be present in the class name. As such its output will not change in many
+cases.
+
+However, some node classes have been moved to a different namespace or renamed, which will result in a different
+`Node::getType()` output:
+
+```
+Expr_AssignBitwiseAnd => Expr_AssignOp_BitwiseAnd
+Expr_AssignBitwiseOr  => Expr_AssignOp_BitwiseOr
+Expr_AssignBitwiseXor => Expr_AssignOp_BitwiseXor
+Expr_AssignConcat     => Expr_AssignOp_Concat
+Expr_AssignDiv        => Expr_AssignOp_Div
+Expr_AssignMinus      => Expr_AssignOp_Minus
+Expr_AssignMod        => Expr_AssignOp_Mod

+Expr_ShiftLeft        => Expr_BinaryOp_ShiftLeft
+Expr_ShiftRight       => Expr_BinaryOp_ShiftRight
+Expr_Smaller          => Expr_BinaryOp_Smaller
+Expr_SmallerOrEqual   => Expr_BinaryOp_SmallerOrEqual
+
+Scalar_ClassConst     => Scalar_MagicConst_Class
+Scalar_DirConst       => Scalar_MagicConst_Dir
+Scalar_FileConst      => Scalar_MagicConst_File
+Scalar_FuncConst      => Scalar_MagicConst_Function
+Scalar_LineConst      => Scalar_MagicConst_Line
+Scalar_MethodConst    => Scalar_MagicConst_Method
+Scalar_NSConst        => Scalar_MagicConst_Namespace
+Scalar_TraitConst     => Scalar_MagicConst_Trait
+```
+
+These changes may affect custom pretty printers and code comparing the return value of `Node::getType()` to specific
+strings.
+
+### Miscellaneous
+
+  * The classes `Template` and `TemplateLoader` have been removed. You should use some other [code generation][code_gen]

+Upgrading from PHP-Parser 1.x to 2.0
+====================================
+
+### PHP version requirements
+
+PHP-Parser now requires PHP 5.4 or newer to run. It is however still possible to *parse* PHP 5.2 and
+PHP 5.3 source code, while running on a newer version.
+
+### Creating a parser instance
+
+Parser instances should now be created through the `ParserFactory`. Old direct instantiation code
+will not work, because the parser class was renamed.
+
+Old:
+
+```php
+use PhpParser\Parser, PhpParser\Lexer;
+$parser = new Parser(new Lexer\Emulative);
+```
+
+New:
+
+```php
+use PhpParser\ParserFactory;
+$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
+```
+
+The first argument to `ParserFactory` determines how different PHP versions are handled. The
+possible values are:
+
+ * `ParserFactory::PREFER_PHP7`: Try to parse code as PHP 7. If this fails, try to parse it as PHP 5.
+ * `ParserFactory::PREFER_PHP5`: Try to parse code as PHP 5. If this fails, try to parse it as PHP 7.
+ * `ParserFactory::ONLY_PHP7`: Parse code as PHP 7.
+ * `ParserFactory::ONLY_PHP5`: Parse code as PHP 5.
+
+For most practical purposes the difference between `PREFER_PHP7` and `PREFER_PHP5` is mainly whether
+a scalar type hint like `string` will be stored as `'string'` (PHP 7) or as `new Name('string')`
+(PHP 5).
+
+To use a custom lexer, pass it as the second argument to the `create()` method:
+
+```php
+use PhpParser\ParserFactory;
+$lexer = new MyLexer;
+$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7, $lexer);
+```
+
+### Rename of the `PhpParser\Parser` class
+
+`PhpParser\Parser` is now an interface, which is implemented by `Parser\Php5`, `Parser\Php7` and
+`Parser\Multiple`. Parser tokens are now defined in `Parser\Tokens`. If you use the `ParserFactory`
+described above to create your parser instance, these changes should have no further impact on you.
+
+### Removal of legacy aliases
+
+All legacy aliases for classes have been removed. This includes the old non-namespaced `PHPParser_`
+classes, as well as the classes that had to be renamed for PHP 7 support.
+
+### Deprecations
+
+The `set()`, `setFirst()`, `append()` and `prepend()` methods of the `Node\Name` class have been
+deprecated. Instead `Name::concat()` and `Name->slice()` should be used.
+
+### Miscellaneous
+
+* The `NodeTraverser` no longer clones nodes by default. If you want to restore the old behavior,
+  pass `true` to the constructor.
+* The legacy node format has been removed. If you use custom nodes, they are now expected to
+  implement a `getSubNodeNames()` method.
+* The default value for `Scalar` node constructors was removed. This means that something like
+  `new LNumber()` should be replaced by `new LNumber(0)`.
+* String parts of encapsed strings are now represented using `Scalar\EncapsStringPart` nodes, while
+  previously raw strings were used. This affects the `parts` child of `Scalar\Encaps` and
+  `Expr\ShellExec`.

+Upgrading from PHP-Parser 2.x to 3.0
+====================================
+
+The backwards-incompatible changes in this release may be summarized as follows:
+
+ * The specific details of the node representation have changed in some cases, primarily to
+   accomodate new PHP 7.1 features.
+ * There have been significant changes to the error recovery implementation. This may affect you,
+   if you used the error recovery mode or have a custom lexer implementation.
+ * A number of deprecated methods were removed.
+
+### PHP version requirements
+
+PHP-Parser now requires PHP 5.5 or newer to run. It is however still possible to *parse* PHP 5.2,
+5.3 and 5.4 source code, while running on a newer version.
+
+### Changes to the node structure
+
+The following changes are likely to require code changes if the respective nodes are used:
+
+ * The `List` subnode `vars` has been renamed to `items` and now contains `ArrayItem`s instead of
+   plain variables.
+ * The `Catch` subnode `type` has been renamed to `types` and is now an array of `Name`s.
+ * The `TryCatch` subnode `finallyStmts` has been replaced with a `finally` subnode that holds an
+   explicit `Finally` node.
+ * The `type` subnode on `Class`, `ClassMethod` and `Property` has been renamed to `flags`. The
+   `type` subnode has retained for backwards compatibility and is populated to the same value as
+   `flags`. However, writes to `type` will not update `flags` and use of `type` is discouraged.
+
+The following changes are unlikely to require code changes:
+
+ * The `ClassConst` constructor changed to accept an additional `flags` subnode.
+ * The `Trait` constructor now has the same form as the `Class` and `Interface` constructors: It
+   takes an array of subnodes. Unlike classes/interfaces, traits can only have a `stmts` subnode.
+ * The `Array` subnode `items` may now contain `null` elements (due to destructuring).
+ * `void` and `iterable` types are now stored as strings if the PHP 7 parser is used. Previously
+   these would have been represented as `Name` instances.
+
+### Changes to error recovery mode
+
+Previously, error recovery mode was enabled by setting the `throwOnError` option to `false` when
+creating the parser, while collected errors were retrieved using the `getErrors()` method:
+
+```php
+$lexer = ...;
+$parser = (new ParserFactory)->create(ParserFactor::ONLY_PHP7, $lexer, [
+    'throwOnError' => true,
+]);
+
+$stmts = $parser->parse($code);
+$errors = $parser->getErrors();
+if ($errors) {
+    handleErrors($errors);
+}
+processAst($stmts);
+```
+
+Both the `throwOnError` option and the `getErrors()` method have been removed in PHP-Parser 3.0.
+Instead an instance of `ErrorHandler\Collecting` should be passed to the `parse()` method:
+
+```php
+$lexer = ...;
+$parser = (new ParserFactory)->create(ParserFactor::ONLY_PHP7, $lexer);
+
+$errorHandler = new ErrorHandler\Collecting;
+$stmts = $parser->parse($code, $errorHandler);
+if ($errorHandler->hasErrors()) {
+    handleErrors($errorHandler->getErrors());
+}
+processAst($stmts);
+```
+
+#### Multiple parser fallback in error recovery mode
+
+As a result of this change, if a `Multiple` parser is used (e.g. through the `ParserFactory` using
+`PREFER_PHP7` or `PREFER_PHP5`), it will now return the result of the first *non-throwing* parse. As
+parsing never throws in error recovery mode, the result from the first parser will always be
+returned.
+
+The PHP 7 parser is a superset of the PHP 5 parser, with the exceptions that `=& new` and
+`global $$foo->bar` are not supported (other differences are in representation only). The PHP 7
+parser will be able to recover from the error in both cases. For this reason, this change will
+likely pass unnoticed if you do not specifically test for this syntax.
+
+It is possible to restore the precise previous behavior with the following code:
+
+```php
+$lexer = ...;
+$parser7 = new Parser\Php7($lexer);
+$parser5 = new Parser\Php5($lexer);
+
+$errors7 = new ErrorHandler\Collecting();
+$stmts7 = $parser7->parse($code, $errors7);
+if ($errors7->hasErrors()) {
+    $errors5 = new ErrorHandler\Collecting();
+    $stmts5 = $parser5->parse($code, $errors5);
+    if (!$errors5->hasErrors()) {
+        // If PHP 7 parse has errors but PHP 5 parse has no errors, use PHP 5 result
+        return [$stmts5, $errors5];
+    }
+}
+// If PHP 7 succeeds or both fail use PHP 7 result
+return [$stmts7, $errors7];
+```
+
+#### Error handling in the lexer
+
+In order to support recovery from lexer errors, the signature of the `startLexing()` method changed
+to optionally accept an `ErrorHandler`:
+
+```php
+// OLD
+public function startLexing($code);
+// NEW
+public function startLexing($code, ErrorHandler $errorHandler = null);
+```
+
+If you use a custom lexer with overriden `startLexing()` method, it needs to be changed to accept
+the extra parameter. The value should be passed on to the parent method.
+
+#### Error checks in node constructors
+
+The constructors of certain nodes used to contain additional checks for semantic errors, such as
+creating a try block without either catch or finally. These checks have been moved from the node
+constructors into the parser. This allows recovery from such errors, as well as representing the
+resulting (invalid) AST.
+
+This means that certain error conditions are no longer checked for manually constructed nodes.
+
+### Removed methods, arguments, options
+
+The following methods, arguments or options have been removed:
+
+ * `Comment::setLine()`, `Comment::setText()`: Create new `Comment` instances instead.
+ * `Name::set()`, `Name::setFirst()`, `Name::setLast()`, `Name::append()`, `Name::prepend()`:
+    Use `Name::concat()` in combination with `Name::slice()` instead.
+ * `Error::getRawLine()`, `Error::setRawLine()`. Use `Error::getStartLine()` and
+   `Error::setStartLine()` instead.
+ * `Parser::getErrors()`. Use `ErrorHandler\Collecting` instead.
+ * `$separator` argument of `Name::toString()`. Use `strtr()` instead, if you really need it.
+ * `$cloneNodes` argument of `NodeTraverser::__construct()`. Explicitly clone nodes in the visitor
+   instead.
+ * `throwOnError` parser option. Use `ErrorHandler\Collecting` instead.
+
+### Miscellaneous
+
+ * All methods on `PrettyPrinter\Standard` are now protected. Previoulsy most of them were public.
+   The pretty printer should only be invoked using the `prettyPrint()`, `prettyPrintFile()` and
+   `prettyPrintExpr()` methods.
+ * The node dumper now prints numeric values that act as enums/flags in a string representation.
+   If node dumper results are used in tests, updates may be needed to account for this.
+ * The constants on `NameTraverserInterface` have been moved into the `NameTraverser` class.
+ * The emulative lexer now directly postprocesses tokens, instead of using `~__EMU__~` sequences.
+   This changes the protected API of the emulative lexer.
+ * The `Name::slice()` method now returns `null` for empty slices, previously `new Name([])` was
+   used. `Name::concat()` now also supports concatenation with `null`.

+Introduction
+============
+
+This project is a PHP 5.2 to PHP 7.1 parser **written in PHP itself**.
+
+What is this for?
+-----------------
+
+A parser is useful for [static analysis][0], manipulation of code and basically any other
+application dealing with code programmatically. A parser constructs an [Abstract Syntax Tree][1]
+(AST) of the code and thus allows dealing with it in an abstract and robust way.
+
+There are other ways of processing source code. One that PHP supports natively is using the
+token stream generated by [`token_get_all`][2]. The token stream is much more low level than
+the AST and thus has different applications: It allows to also analyze the exact formatting of
+a file. On the other hand the token stream is much harder to deal with for more complex analysis.
+For example an AST abstracts away the fact that in PHP variables can be written as `$foo`, but also
+as `$$bar`, `${'foobar'}` or even `${!${''}=barfoo()}`. You don't have to worry about recognizing
+all the different syntaxes from a stream of tokens.
+
+Another question is: Why would I want to have a PHP parser *written in PHP*? Well, PHP might not be
+a language especially suited for fast parsing, but processing the AST is much easier in PHP than it
+would be in other, faster languages like C. Furthermore the people most probably wanting to do
+programmatic PHP code analysis are incidentally PHP developers, not C developers.
+
+What can it parse?
+------------------
+
+The parser supports parsing PHP 5.2-5.6 and PHP 7.
+
+As the parser is based on the tokens returned by `token_get_all` (which is only able to lex the PHP
+version it runs on), additionally a wrapper for emulating tokens from newer versions is provided.
+This allows to parse PHP 7.1 source code running on PHP 5.5, for example. This emulation is somewhat
+hacky and not perfect, but it should work well on any sane code.
+
+What output does it produce?
+----------------------------
+
+The parser produces an [Abstract Syntax Tree][1] (AST) also known as a node tree. How this looks like
+can best be seen in an example. The program `<?php echo 'Hi', 'World';` will give you a node tree
+roughly looking like this:
+
+```
+array(
+    0: Stmt_Echo(
+        exprs: array(
+            0: Scalar_String(
+                value: Hi
+            )
+            1: Scalar_String(
+                value: World
+            )
+        )
+    )
+)
+```
+
+This matches the structure of the code: An echo statement, which takes two strings as expressions,
+with the values `Hi` and `World!`.
+
+You can also see that the AST does not contain any whitespace information (but most comments are saved).
+So using it for formatting analysis is not possible.
+
+What else can it do?
+--------------------
+
+Apart from the parser itself this package also bundles support for some other, related features:
+
+ * Support for pretty printing, which is the act of converting an AST into PHP code. Please note
+   that "pretty printing" does not imply that the output is especially pretty. It's just how it's
+   called ;)
+ * Support for serializing and unserializing the node tree to XML
+ * Support for dumping the node tree in a human readable form (see the section above for an
+   example of how the output looks like)
+ * Infrastructure for traversing and changing the AST (node traverser and node visitors)
+ * A node visitor for resolving namespaced names

+Usage of basic components
+=========================
+
+This document explains how to use the parser, the pretty printer and the node traverser.
+
+Bootstrapping
+-------------
+
+To bootstrap the library, include the autoloader generated by composer:
+
+```php
+require 'path/to/vendor/autoload.php';
+```
+
+Additionally you may want to set the `xdebug.max_nesting_level` ini option to a higher value:
+
+```php
+ini_set('xdebug.max_nesting_level', 3000);
+```
+
+This ensures that there will be no errors when traversing highly nested node trees. However, it is
+preferable to disable XDebug completely, as it can easily make this library more than five times
+slower.
+
+Parsing
+-------
+
+In order to parse code, you first have to create a parser instance:
+
+```php
+use PhpParser\ParserFactory;
+$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
+```
+
+The factory accepts a kind argument, that determines how different PHP versions are treated:
+
+Kind | Behavior
+-----|---------
+`ParserFactory::PREFER_PHP7` | Try to parse code as PHP 7. If this fails, try to parse it as PHP 5.
+`ParserFactory::PREFER_PHP5` | Try to parse code as PHP 5. If this fails, try to parse it as PHP 7.
+`ParserFactory::ONLY_PHP7` | Parse code as PHP 7.
+`ParserFactory::ONLY_PHP5` | Parse code as PHP 5.
+
+Unless you have strong reason to use something else, `PREFER_PHP7` is a reasonable default.
+
+The `create()` method optionally accepts a `Lexer` instance as the second argument. Some use cases
+that require customized lexers are discussed in the [lexer documentation](component/Lexer.markdown).
+
+Subsequently you can pass PHP code (including the opening `<?php` tag) to the `parse` method in order to
+create a syntax tree. If a syntax error is encountered, an `PhpParser\Error` exception will be thrown:
+
+```php
+use PhpParser\Error;
+use PhpParser\ParserFactory;
+
+$code = '<?php // some code';
+$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
+
+try {
+    $stmts = $parser->parse($code);
+    // $stmts is an array of statement nodes
+} catch (Error $e) {
+    echo 'Parse Error: ', $e->getMessage();
+}
+```
+
+A parser instance can be reused to parse multiple files.
+
+Node tree
+---------
+
+If you use the above code with `$code = "<?php echo 'Hi ', hi\\getTarget();"` the parser will
+generate a node tree looking like this:
+
+```
+array(
+    0: Stmt_Echo(
+        exprs: array(
+            0: Scalar_String(
+                value: Hi
+            )
+            1: Expr_FuncCall(
+                name: Name(
+                    parts: array(
+                        0: hi
+                        1: getTarget
+                    )
+                )
+                args: array(
+                )
+            )
+        )
+    )
+)
+```
+
+Thus `$stmts` will contain an array with only one node, with this node being an instance of
+`PhpParser\Node\Stmt\Echo_`.
+
+As PHP is a large language there are approximately 140 different nodes. In order to make work
+with them easier they are grouped into three categories:
+
+ * `PhpParser\Node\Stmt`s are statement nodes, i.e. language constructs that do not return
+   a value and can not occur in an expression. For example a class definition is a statement.
+   It doesn't return a value and you can't write something like `func(class A {});`.
+ * `PhpParser\Node\Expr`s are expression nodes, i.e. language constructs that return a value
+   and thus can occur in other expressions. Examples of expressions are `$var`
+   (`PhpParser\Node\Expr\Variable`) and `func()` (`PhpParser\Node\Expr\FuncCall`).
+ * `PhpParser\Node\Scalar`s are nodes representing scalar values, like `'string'`
+   (`PhpParser\Node\Scalar\String_`), `0` (`PhpParser\Node\Scalar\LNumber`) or magic constants
+   like `__FILE__` (`PhpParser\Node\Scalar\MagicConst\File`). All `PhpParser\Node\Scalar`s extend
+   `PhpParser\Node\Expr`, as scalars are expressions, too.
+ * There are some nodes not in either of these groups, for example names (`PhpParser\Node\Name`)
+   and call arguments (`PhpParser\Node\Arg`).
+
+Some node class names have a trailing `_`. This is used whenever the class name would otherwise clash
+with a PHP keyword.
+
+Every node has a (possibly zero) number of subnodes. You can access subnodes by writing
+`$node->subNodeName`. The `Stmt\Echo_` node has only one subnode `exprs`. So in order to access it
+in the above example you would write `$stmts[0]->exprs`. If you wanted to access the name of the function
+call, you would write `$stmts[0]->exprs[1]->name`.
+
+All nodes also define a `getType()` method that returns the node type. The type is the class name
+without the `PhpParser\Node\` prefix and `\` replaced with `_`. It also does not contain a trailing
+`_` for reserved-keyword class names.
+
+It is possible to associate custom metadata with a node using the `setAttribute()` method. This data
+can then be retrieved using `hasAttribute()`, `getAttribute()` and `getAttributes()`.
+
+By default the lexer adds the `startLine`, `endLine` and `comments` attributes. `comments` is an array
+of `PhpParser\Comment[\Doc]` instances.
+
+The start line can also be accessed using `getLine()`/`setLine()` (instead of `getAttribute('startLine')`).
+The last doc comment from the `comments` attribute can be obtained using `getDocComment()`.
+
+Pretty printer
+--------------
+
+The pretty printer component compiles the AST back to PHP code. As the parser does not retain formatting
+information the formatting is done using a specified scheme. Currently there is only one scheme available,
+namely `PhpParser\PrettyPrinter\Standard`.
+
+```php
+use PhpParser\Error;
+use PhpParser\ParserFactory;
+use PhpParser\PrettyPrinter;
+
+$code = "<?php echo 'Hi ', hi\\getTarget();";
+
+$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
+$prettyPrinter = new PrettyPrinter\Standard;
+
+try {
+    // parse
+    $stmts = $parser->parse($code);
+
+    // change
+    $stmts[0]         // the echo statement
+          ->exprs     // sub expressions
+          [0]         // the first of them (the string node)
+          ->value     // it's value, i.e. 'Hi '
+          = 'Hello '; // change to 'Hello '
+
+    // pretty print
+    $code = $prettyPrinter->prettyPrint($stmts);
+
+    echo $code;
+} catch (Error $e) {
+    echo 'Parse Error: ', $e->getMessage();
+}
+```
+
+The above code will output:
+
+    <?php echo 'Hello ', hi\getTarget();
+
+As you can see the source code was first parsed using `PhpParser\Parser->parse()`, then changed and then
+again converted to code using `PhpParser\PrettyPrinter\Standard->prettyPrint()`.
+
+The `prettyPrint()` method pretty prints a statements array. It is also possible to pretty print only a
+single expression using `prettyPrintExpr()`.
+
+The `prettyPrintFile()` method can be used to print an entire file. This will include the opening `<?php` tag
+and handle inline HTML as the first/last statement more gracefully.
+
+Node traversation
+-----------------
+
+The above pretty printing example used the fact that the source code was known and thus it was easy to
+write code that accesses a certain part of a node tree and changes it. Normally this is not the case.
+Usually you want to change / analyze code in a generic way, where you don't know how the node tree is
+going to look like.
+
+For this purpose the parser provides a component for traversing and visiting the node tree. The basic
+structure of a program using this `PhpParser\NodeTraverser` looks like this:
+
+```php
+use PhpParser\NodeTraverser;
+use PhpParser\ParserFactory;
+use PhpParser\PrettyPrinter;
+
+$parser        = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
+$traverser     = new NodeTraverser;
+$prettyPrinter = new PrettyPrinter\Standard;
+
+// add your visitor
+$traverser->addVisitor(new MyNodeVisitor);
+
+try {
+    $code = file_get_contents($fileName);
+
+    // parse
+    $stmts = $parser->parse($code);
+
+    // traverse
+    $stmts = $traverser->traverse($stmts);
+
+    // pretty print
+    $code = $prettyPrinter->prettyPrintFile($stmts);
+
+    echo $code;
+} catch (PhpParser\Error $e) {
+    echo 'Parse Error: ', $e->getMessage();
+}
+```
+
+The corresponding node visitor might look like this:
+
+```php
+use PhpParser\Node;
+use PhpParser\NodeVisitorAbstract;
+
+class MyNodeVisitor extends NodeVisitorAbstract
+{
+    public function leaveNode(Node $node) {
+        if ($node instanceof Node\Scalar\String_) {
+            $node->value = 'foo';
+        }
+    }
+}
+```
+
+The above node visitor would change all string literals in the program to `'foo'`.
+
+All visitors must implement the `PhpParser\NodeVisitor` interface, which defines the following four
+methods:
+
+```php
+public function beforeTraverse(array $nodes);
+public function enterNode(\PhpParser\Node $node);
+public function leaveNode(\PhpParser\Node $node);
+public function afterTraverse(array $nodes);
+```
+
+The `beforeTraverse()` method is called once before the traversal begins and is passed the nodes the
+traverser was called with. This method can be used for resetting values before traversation or
+preparing the tree for traversal.
+
+The `afterTraverse()` method is similar to the `beforeTraverse()` method, with the only difference that
+it is called once after the traversal.
+
+The `enterNode()` and `leaveNode()` methods are called on every node, the former when it is entered,
+i.e. before its subnodes are traversed, the latter when it is left.
+
+All four methods can either return the changed node or not return at all (i.e. `null`) in which
+case the current node is not changed.
+
+The `enterNode()` method can additionally return the value `NodeTraverser::DONT_TRAVERSE_CHILDREN`,
+which instructs the traverser to skip all children of the current node.
+
+The `leaveNode()` method can additionally return the value `NodeTraverser::REMOVE_NODE`, in which
+case the current node will be removed from the parent array. Furthermore it is possible to return
+an array of nodes, which will be merged into the parent array at the offset of the current node.
+I.e. if in `array(A, B, C)` the node `B` should be replaced with `array(X, Y, Z)` the result will
+be `array(A, X, Y, Z, C)`.
+
+Instead of manually implementing the `NodeVisitor` interface you can also extend the `NodeVisitorAbstract`
+class, which will define empty default implementations for all the above methods.
+
+The NameResolver node visitor
+-----------------------------
+
+One visitor is already bundled with the package: `PhpParser\NodeVisitor\NameResolver`. This visitor
+helps you work with namespaced code by trying to resolve most names to fully qualified ones.
+
+For example, consider the following code:
+
+    use A as B;
+    new B\C();
+
+In order to know that `B\C` really is `A\C` you would need to track aliases and namespaces yourself.
+The `NameResolver` takes care of that and resolves names as far as possible.
+
+After running it most names will be fully qualified. The only names that will stay unqualified are
+unqualified function and constant names. These are resolved at runtime and thus the visitor can't
+know which function they are referring to. In most cases this is a non-issue as the global functions
+are meant.
+
+Also the `NameResolver` adds a `namespacedName` subnode to class, function and constant declarations
+that contains the namespaced name instead of only the shortname that is available via `name`.
+
+Example: Converting namespaced code to pseudo namespaces
+--------------------------------------------------------
+
+A small example to understand the concept: We want to convert namespaced code to pseudo namespaces
+so it works on 5.2, i.e. names like `A\\B` should be converted to `A_B`. Note that such conversions
+are fairly complicated if you take PHP's dynamic features into account, so our conversion will
+assume that no dynamic features are used.
+
+We start off with the following base code:
+
+```php
+use PhpParser\ParserFactory;
+use PhpParser\PrettyPrinter;
+use PhpParser\NodeTraverser;
+use PhpParser\NodeVisitor\NameResolver;
+
+$inDir  = '/some/path';
+$outDir = '/some/other/path';
+
+$parser        = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
+$traverser     = new NodeTraverser;
+$prettyPrinter = new PrettyPrinter\Standard;
+
+$traverser->addVisitor(new NameResolver); // we will need resolved names
+$traverser->addVisitor(new NamespaceConverter); // our own node visitor
+
+// iterate over all .php files in the directory
+$files = new \RecursiveIteratorIterator(new \RecursiveDirectoryIterator($inDir));
+$files = new \RegexIterator($files, '/\.php$/');
+
+foreach ($files as $file) {
+    try {
+        // read the file that should be converted
+        $code = file_get_contents($file);
+
+        // parse
+        $stmts = $parser->parse($code);
+
+        // traverse
+        $stmts = $traverser->traverse($stmts);
+
+        // pretty print
+        $code = $prettyPrinter->prettyPrintFile($stmts);
+
+        // write the converted file to the target directory
+        file_put_contents(
+            substr_replace($file->getPathname(), $outDir, 0, strlen($inDir)),
+            $code
+        );
+    } catch (PhpParser\Error $e) {
+        echo 'Parse Error: ', $e->getMessage();
+    }
+}
+```
+
+Now lets start with the main code, the `NodeVisitor\NamespaceConverter`. One thing it needs to do
+is convert `A\\B` style names to `A_B` style ones.
+
+```php
+use PhpParser\Node;
+
+class NamespaceConverter extends \PhpParser\NodeVisitorAbstract
+{
+    public function leaveNode(Node $node) {
+        if ($node instanceof Node\Name) {
+            return new Node\Name($node->toString('_'));
+        }
+    }
+}
+```
+
+The above code profits from the fact that the `NameResolver` already resolved all names as far as
+possible, so we don't need to do that. We only need to create a string with the name parts separated
+by underscores instead of backslashes. This is what `$node->toString('_')` does. (If you want to
+create a name with backslashes either write `$node->toString()` or `(string) $node`.) Then we create
+a new name from the string and return it. Returning a new node replaces the old node.
+
+Another thing we need to do is change the class/function/const declarations. Currently they contain
+only the shortname (i.e. the last part of the name), but they need to contain the complete name including
+the namespace prefix:
+
+```php
+use PhpParser\Node;
+use PhpParser\Node\Stmt;
+
+class NodeVisitor_NamespaceConverter extends \PhpParser\NodeVisitorAbstract
+{
+    public function leaveNode(Node $node) {
+        if ($node instanceof Node\Name) {
+            return new Node\Name($node->toString('_'));
+        } elseif ($node instanceof Stmt\Class_
+                  || $node instanceof Stmt\Interface_
+                  || $node instanceof Stmt\Function_) {
+            $node->name = $node->namespacedName->toString('_');
+        } elseif ($node instanceof Stmt\Const_) {
+            foreach ($node->consts as $const) {
+                $const->name = $const->namespacedName->toString('_');
+            }
+        }
+    }
+}
+```
+
+There is not much more to it than converting the namespaced name to string with `_` as separator.
+
+The last thing we need to do is remove the `namespace` and `use` statements:
+
+```php
+use PhpParser\Node;
+use PhpParser\Node\Stmt;
+
+class NodeVisitor_NamespaceConverter extends \PhpParser\NodeVisitorAbstract
+{
+    public function leaveNode(Node $node) {
+        if ($node instanceof Node\Name) {
+            return new Node\Name($node->toString('_'));
+        } elseif ($node instanceof Stmt\Class_
+                  || $node instanceof Stmt\Interface_
+                  || $node instanceof Stmt\Function_) {
+            $node->name = $node->namespacedName->toString('_');
+        } elseif ($node instanceof Stmt\Const_) {
+            foreach ($node->consts as $const) {
+                $const->name = $const->namespacedName->toString('_');
+            }
+        } elseif ($node instanceof Stmt\Namespace_) {
+            // returning an array merges is into the parent array
+            return $node->stmts;
+        } elseif ($node instanceof Stmt\Use_) {
+            // returning false removed the node altogether
+            return false;
+        }
+    }
+}
+```
+
+That's all.

+Other node tree representations
+===============================
+
+It is possible to convert the AST into several textual representations, which serve different uses.
+
+Simple serialization
+--------------------
+
+It is possible to serialize the node tree using `serialize()` and also unserialize it using
+`unserialize()`. The output is not human readable and not easily processable from anything
+but PHP, but it is compact and generates quickly. The main application thus is in caching.
+
+Human readable dumping
+----------------------
+
+Furthermore it is possible to dump nodes into a human readable format using the `dump` method of
+`PhpParser\NodeDumper`. This can be used for debugging.
+
+```php
+$code = <<<'CODE'
+<?php
+
+function printLine($msg) {
+    echo $msg, "\n";
+}
+
+printLine('Hello World!!!');
+CODE;
+
+$parser = (new PhpParser\ParserFactory)->create(PhpParser\ParserFactory::PREFER_PHP7);
+$nodeDumper = new PhpParser\NodeDumper;
+
+try {
+    $stmts = $parser->parse($code);
+
+    echo $nodeDumper->dump($stmts), "\n";
+} catch (PhpParser\Error $e) {
+    echo 'Parse Error: ', $e->getMessage();
+}
+```
+
+The above script will have an output looking roughly like this:
+
+```
+array(
+    0: Stmt_Function(
+        byRef: false
+        params: array(
+            0: Param(
+                name: msg
+                default: null
+                type: null
+                byRef: false
+            )
+        )
+        stmts: array(
+            0: Stmt_Echo(
+                exprs: array(
+                    0: Expr_Variable(
+                        name: msg
+                    )
+                    1: Scalar_String(
+                        value:
+
+                    )
+                )
+            )
+        )
+        name: printLine
+    )
+    1: Expr_FuncCall(
+        name: Name(
+            parts: array(
+                0: printLine
+            )
+        )
+        args: array(
+            0: Arg(
+                value: Scalar_String(
+                    value: Hello World!!!
+                )
+                byRef: false
+            )
+        )
+    )
+)
+```
+
+JSON encoding
+-------------
+
+Nodes (and comments) implement the `JsonSerializable` interface. As such, it is possible to JSON
+encode the AST directly using `json_encode()`:
+
+```php
+$code = <<<'CODE'
+<?php
+
+function printLine($msg) {
+    echo $msg, "\n";
+}
+
+printLine('Hello World!!!');
+CODE;
+
+$parser = (new PhpParser\ParserFactory)->create(PhpParser\ParserFactory::PREFER_PHP7);
+$nodeDumper = new PhpParser\NodeDumper;
+
+try {
+    $stmts = $parser->parse($code);
+
+    echo json_encode($stmts, JSON_PRETTY_PRINT), "\n";
+} catch (PhpParser\Error $e) {
+    echo 'Parse Error: ', $e->getMessage();
+}
+```
+
+This will result in the following output (which includes attributes):
+
+```json
+[
+    {
+        "nodeType": "Stmt_Function",
+        "byRef": false,
+        "name": "printLine",
+        "params": [
+            {
+                "nodeType": "Param",
+                "type": null,
+                "byRef": false,
+                "variadic": false,
+                "name": "msg",
+                "default": null,

+There is currently no mechanism to convert JSON back into a node tree. Furthermore, not all ASTs
+can be JSON encoded. In particular, JSON only supports UTF-8 strings.
+
+Serialization to XML
+--------------------
+
+It is also possible to serialize the node tree to XML using `PhpParser\Serializer\XML->serialize()`
+and to unserialize it using `PhpParser\Unserializer\XML->unserialize()`. This is useful for
+interfacing with other languages and applications or for doing transformation using XSLT.
+
+```php

+Code generation
+===============
+
+It is also possible to generate code using the parser, by first creating an Abstract Syntax Tree and then using the
+pretty printer to convert it to PHP code. To simplify code generation, the project comes with builders which allow
+creating node trees using a fluid interface, instead of instantiating all nodes manually. Builders are available for
+the following syntactic elements:
+
+ * namespaces and use statements
+ * classes, interfaces and traits
+ * methods, functions and parameters
+ * properties
+
+Here is an example:
+
+```php
+use PhpParser\BuilderFactory;
+use PhpParser\PrettyPrinter;
+use PhpParser\Node;
+
+$factory = new BuilderFactory;
+$node = $factory->namespace('Name\Space')
+    ->addStmt($factory->use('Some\Other\Thingy')->as('SomeOtherClass'))
+    ->addStmt($factory->class('SomeClass')
+        ->extend('SomeOtherClass')
+        ->implement('A\Few', '\Interfaces')
+        ->makeAbstract() // ->makeFinal()
+
+        ->addStmt($factory->method('someMethod')
+            ->makePublic()
+            ->makeAbstract() // ->makeFinal()
+            ->setReturnType('bool')
+            ->addParam($factory->param('someParam')->setTypeHint('SomeClass'))
+            ->setDocComment('/**
+                              * This method does something.
+                              *
+                              * @param SomeClass And takes a parameter
+                              */')
+        )
+
+        ->addStmt($factory->method('anotherMethod')
+            ->makeProtected() // ->makePublic() [default], ->makePrivate()
+            ->addParam($factory->param('someParam')->setDefault('test'))
+            // it is possible to add manually created nodes
+            ->addStmt(new Node\Expr\Print_(new Node\Expr\Variable('someParam')))
+        )
+
+        // properties will be correctly reordered above the methods
+        ->addStmt($factory->property('someProperty')->makeProtected())
+        ->addStmt($factory->property('anotherProperty')->makePrivate()->setDefault(array(1, 2, 3)))
+    )
+
+    ->getNode()
+;
+
+$stmts = array($node);
+$prettyPrinter = new PrettyPrinter\Standard();
+echo $prettyPrinter->prettyPrintFile($stmts);
+```
+
+This will produce the following output with the standard pretty printer:
+
+```php
+<?php
+
+namespace Name\Space;
+
+use Some\Other\Thingy as SomeClass;
+abstract class SomeClass extends SomeOtherClass implements A\Few, \Interfaces
+{
+    protected $someProperty;
+    private $anotherProperty = array(1, 2, 3);
+    /**
+     * This method does something.
+     *
+     * @param SomeClass And takes a parameter
+     */
+    public abstract function someMethod(SomeClass $someParam) : bool;
+    protected function anotherMethod($someParam = 'test')
+    {
+        print $someParam;
+    }
+}
+```

+Error handling
+==============
+
+Errors during parsing or analysis are represented using the `PhpParser\Error` exception class. In addition to an error
+message, an error can also store additional information about the location the error occurred at.
+
+How much location information is available depends on the origin of the error and how many lexer attributes have been
+enabled. At a minimum the start line of the error is usually available.
+
+Column information
+------------------
+
+In order to receive information about not only the line, but also the column span an error occurred at, the file
+position attributes in the lexer need to be enabled:
+
+```php
+$lexer = new PhpParser\Lexer(array(
+    'usedAttributes' => array('comments', 'startLine', 'endLine', 'startFilePos', 'endFilePos'),
+));
+$parser = (new PhpParser\ParserFactory)->create(PhpParser\ParserFactory::PREFER_PHP7, $lexer);
+
+try {
+    $stmts = $parser->parse($code);
+    // ...
+} catch (PhpParser\Error $e) {
+    // ...
+}
+```
+
+Before using column information its availability needs to be checked with `$e->hasColumnInfo()`, as the precise
+location of an error cannot always be determined. The methods for retrieving column information also have to be passed
+the source code of the parsed file. An example for printing an error:
+
+```php
+if ($e->hasColumnInfo()) {
+    echo $e->getRawMessage() . ' from ' . $e->getStartLine() . ':' . $e->getStartColumn($code)
+        . ' to ' . $e->getEndLine() . ':' . $e->getEndColumn($code);
+    // or:
+    echo $e->getMessageWithColumnInfo();
+} else {
+    echo $e->getMessage();
+}
+```
+
+Both line numbers and column numbers are 1-based. EOF errors will be located at the position one past the end of the
+file.
+
+Error recovery
+--------------
+
+The error behavior of the parser (and other components) is controlled by an `ErrorHandler`. Whenever an error is
+encountered, `ErrorHandler::handleError()` is invoked. The default error handling strategy is `ErrorHandler\Throwing`,
+which will immediately throw when an error is encountered.
+
+To instead collect all encountered errors into an array, while trying to continue parsing the rest of the source code,
+an instance of `ErrorHandler\Collecting` can be passed to the `Parser::parse()` method. A usage example:
+
+```php
+$parser = (new PhpParser\ParserFactory)->create(PhpParser\ParserFactory::ONLY_PHP7);
+$errorHandler = new PhpParser\ErrorHandler\Collecting;
+
+$stmts = $parser->parse($code, $errorHandler);
+
+if ($errorHandler->hasErrors()) {
+    foreach ($errorHandler->getErrors() as $error) {
+        // $error is an ordinary PhpParser\Error
+    }
+}
+
+if (null !== $stmts) {
+    // $stmts is a best-effort partial AST
+}
+```
+
+The `NameResolver` visitor also accepts an `ErrorHandler` as a constructor argument.

+Lexer component documentation
+=============================
+
+The lexer is responsible for providing tokens to the parser. The project comes with two lexers: `PhpParser\Lexer` and
+`PhpParser\Lexer\Emulative`. The latter is an extension of the former, which adds the ability to emulate tokens of
+newer PHP versions and thus allows parsing of new code on older versions.
+
+This documentation discusses options available for the default lexers and explains how lexers can be extended.
+
+Lexer options
+-------------
+
+The two default lexers accept an `$options` array in the constructor. Currently only the `'usedAttributes'` option is
+supported, which allows you to specify which attributes will be added to the AST nodes. The attributes can then be
+accessed using `$node->getAttribute()`, `$node->setAttribute()`, `$node->hasAttribute()` and `$node->getAttributes()`
+methods. A sample options array:
+
+```php
+$lexer = new PhpParser\Lexer(array(
+    'usedAttributes' => array(
+        'comments', 'startLine', 'endLine'
+    )
+));
+```
+
+The attributes used in this example match the default behavior of the lexer. The following attributes are supported:
+
+ * `comments`: Array of `PhpParser\Comment` or `PhpParser\Comment\Doc` instances, representing all comments that occurred
+   between the previous non-discarded token and the current one. Use of this attribute is required for the
+   `$node->getDocComment()` method to work. The attribute is also needed if you wish the pretty printer to retain
+   comments present in the original code.
+ * `startLine`: Line in which the node starts. This attribute is required for the `$node->getLine()` to work. It is also
+   required if syntax errors should contain line number information.
+ * `endLine`: Line in which the node ends.
+ * `startTokenPos`: Offset into the token array of the first token in the node.
+ * `endTokenPos`: Offset into the token array of the last token in the node.
+ * `startFilePos`: Offset into the code string of the first character that is part of the node.
+ * `endFilePos`: Offset into the code string of the last character that is part of the node.
+
+### Using token positions
+
+The token offset information is useful if you wish to examine the exact formatting used for a node. For example the AST
+does not distinguish whether a property was declared using `public` or using `var`, but you can retrieve this
+information based on the token position:
+
+```php
+function isDeclaredUsingVar(array $tokens, PhpParser\Node\Stmt\Property $prop) {
+    $i = $prop->getAttribute('startTokenPos');
+    return $tokens[$i][0] === T_VAR;
+}
+```
+
+In order to make use of this function, you will have to provide the tokens from the lexer to your node visitor using
+code similar to the following:
+
+```php
+class MyNodeVisitor extends PhpParser\NodeVisitorAbstract {
+    private $tokens;
+    public function setTokens(array $tokens) {
+        $this->tokens = $tokens;
+    }
+
+    public function leaveNode(PhpParser\Node $node) {
+        if ($node instanceof PhpParser\Node\Stmt\Property) {
+            var_dump(isDeclaredUsingVar($this->tokens, $node));
+        }
+    }
+}
+
+$lexer = new PhpParser\Lexer(array(
+    'usedAttributes' => array(
+        'comments', 'startLine', 'endLine', 'startTokenPos', 'endTokenPos'
+    )
+));
+$parser = (new PhpParser\ParserFactory)->create(PhpParser\ParserFactory::PREFER_PHP7, $lexer);
+
+$visitor = new MyNodeVisitor();
+$traverser = new PhpParser\NodeTraverser();
+$traverser->addVisitor($visitor);
+
+try {
+    $stmts = $parser->parse($code);
+    $visitor->setTokens($lexer->getTokens());
+    $stmts = $traverser->traverse($stmts);
+} catch (PhpParser\Error $e) {
+    echo 'Parse Error: ', $e->getMessage();
+}
+```
+
+The same approach can also be used to perform specific modifications in the code, without changing the formatting in
+other places (which is the case when using the pretty printer).
+
+Lexer extension
+---------------
+
+A lexer has to define the following public interface:
+
+    void startLexing(string $code, ErrorHandler $errorHandler = null);
+    array getTokens();
+    string handleHaltCompiler();
+    int getNextToken(string &$value = null, array &$startAttributes = null, array &$endAttributes = null);
+
+The `startLexing()` method is invoked with the source code that is to be lexed (including the opening tag) whenever the
+`parse()` method of the parser is called. It can be used to reset state or preprocess the source code or tokens. The
+passes `ErrorHandler` should be used to report lexing errors.
+
+The `getTokens()` method returns the current token array, in the usual `token_get_all()` format. This method is not
+used by the parser (which uses `getNextToken()`), but is useful in combination with the token position attributes.
+
+The `handleHaltCompiler()` method is called whenever a `T_HALT_COMPILER` token is encountered. It has to return the
+remaining string after the construct (not including `();`).
+
+The `getNextToken()` method returns the ID of the next token (as defined by the `Parser::T_*` constants). If no more
+tokens are available it must return `0`, which is the ID of the `EOF` token. Furthermore the string content of the
+token should be written into the by-reference `$value` parameter (which will then be available as `$n` in the parser).
+
+### Attribute handling
+
+The other two by-ref variables `$startAttributes` and `$endAttributes` define which attributes will eventually be
+assigned to the generated nodes: The parser will take the `$startAttributes` from the first token which is part of the
+node and the `$endAttributes` from the last token that is part of the node.
+
+E.g. if the tokens `T_FUNCTION T_STRING ... '{' ... '}'` constitute a node, then the `$startAttributes` from the
+`T_FUNCTION` token will be taken and the `$endAttributes` from the `'}'` token.
+
+An application of custom attributes is storing the exact original formatting of literals: While the parser does retain
+some information about the formatting of integers (like decimal vs. hexadecimal) or strings (like used quote type), it
+does not preserve the exact original formatting (e.g. leading zeros for integers or escape sequences in strings). This
+can be remedied by storing the original value in an attribute:
+
+```php
+use PhpParser\Lexer;
+use PhpParser\Parser\Tokens;
+
+class KeepOriginalValueLexer extends Lexer // or Lexer\Emulative
+{
+    public function getNextToken(&$value = null, &$startAttributes = null, &$endAttributes = null) {
+        $tokenId = parent::getNextToken($value, $startAttributes, $endAttributes);
+
+        if ($tokenId == Tokens::T_CONSTANT_ENCAPSED_STRING   // non-interpolated string
+            || $tokenId == Tokens::T_ENCAPSED_AND_WHITESPACE // interpolated string
+            || $tokenId == Tokens::T_LNUMBER                 // integer
+            || $tokenId == Tokens::T_DNUMBER                 // floating point number
+        ) {
+            // could also use $startAttributes, doesn't really matter here
+            $endAttributes['originalValue'] = $value;
+        }
+
+        return $tokenId;
+    }
+}
+```

+
+ * Nodes are created using the syntax `Name[..., ...]`. This is transformed into
+   `new Name(..., ..., attributes())`
+ * Some function-like constructs are resolved (see `rebuildParsers.php` for a list)
+
+Building the parser
+===================
+
+In order to rebuild the parser, you need [moriyoshi's fork of kmyacc](https://github.com/moriyoshi/kmyacc-forked).
+After you compiled/installed it, run the `rebuildParsers.php` script.
+
+By default only the `Parser.php` is built. If you want to additionally emit debug symbols and create `y.output`, run the
+script with `--debug`. If you want to retain the preprocessed grammar pass `--keep-tmp-grammar`.
