 Nothing yet.
 
-Version 1.0.0-beta1 (27.03.2014)
+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 5.4. 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)`.
+
+Version 1.4.0 (2015-07-14)
+--------------------------
+
+### Added
+
+* Added interface `PhpParser\Node\FunctionLike`, which is implemented by `Stmt\ClassMethod`,
+  `Stmt\Function_` and `Expr\Closure` nodes. This interface provides getters for their common
+  subnodes.
+* Added `Node\Stmt\ClassLike::getMethod()` to look up a specific method on a class/interface/trait.
+
+### Fixed
+
+* Fixed `isPublic()` return value for implicitly public properties and methods that define and
+  additional modifier like `static` or `abstract`.
+* Properties are now accepted by the trait builder.
+* Fixed `__HALT_COMPILER_OFFSET__` support on HHVM.
+
+Version 1.3.0 (2015-05-02)
+--------------------------
+
+### Added
+
+* Errors can now store the attributes of the node/token where the error occurred. Previously only the start line was
+  stored.
+* If file positions are enabled in the lexer, errors can now provide column information if it is available. See
+  [documentation](https://github.com/nikic/PHP-Parser/blob/master/doc/component/Error.markdown#column-information).
+* The parser now provides an experimental error recovery mode, which can be enabled by disabling the `throwOnError`
+  parser option. In this mode the parser will try to construct a partial AST even if the code is not valid PHP. See
+  [documentation](https://github.com/nikic/PHP-Parser/blob/master/doc/component/Error.markdown#error-recovery).
+* Added support for PHP 7 `yield from` expression. It is represented by `Expr\YieldFrom`.
+* Added support for PHP 7 anonymous classes. These are represented by ordinary `Stmt\Class_` nodes with the name set to
+  `null`. Furthermore this implies that `Expr\New_` can now contain a `Stmt\Class_` in its `class` subnode.
+
+### Fixed
+
+* Fixed registration of PHP 7 aliases, for the case where the old name was used before the new name.
+* Fixed handling of precedence when pretty-printing `print` expressions.
+* Floating point numbers are now pretty-printed with a higher precision.
+* Checks for special class names like `self` are now case-insensitive.
+
+Version 1.2.2 (2015-04-03)
+--------------------------
+
+* The `NameResolver` now resolves parameter type hints when entering the function/method/closure node. As such other
+  visitors running after it will be able to make use of the resolved names at that point already.
+* The autoloader no longer sets the `unserialize_callback_func` ini option on registration - this is not necessary and
+  may cause issues when running PhpUnit tests with process isolation.
+
+Version 1.2.1 (2015-03-24)
+--------------------------
+
+* Fixed registration of the aliases introduced in 1.2.0. Previously the old class names could not be used in
+  `instanceof` checks under some circumstances.
+
+Version 1.2.0 (2015-03-22)
+--------------------------
+
+### Changed
+
+* To ensure compatibility with PHP 7, the following node classes have been renamed:
+
+        OLD                             => NEW
+        PhpParser\Node\Expr\Cast\Bool   => PhpParser\Node\Expr\Cast\Bool_
+        PhpParser\Node\Expr\Cast\Int    => PhpParser\Node\Expr\Cast\Int_
+        PhpParser\Node\Expr\Cast\Object => PhpParser\Node\Expr\Cast\Object_
+        PhpParser\Node\Expr\Cast\String => PhpParser\Node\Expr\Cast\String_
+        PhpParser\Node\Scalar\String    => PhpParser\Node\Scalar\String_
+
+  **The previous class names are still supported as aliases.** However it is strongly encouraged to use the new names
+  in order to make your code compatible with PHP 7.
+
+* Subnodes are now stored using real properties instead of an array. This improves performance and memory usage of the
+  initial parse and subsequent node tree operations. The `NodeAbstract` class still supports the old way of specifying
+  subnodes, however this is *deprecated*. In any case properties that are assigned to a node after creation will no
+  longer be considered as subnodes.
+
+* Methods and property declarations will no longer set the `Stmt\Class_::MODIFIER_PUBLIC` flag if no visibility is
+  explicitly given. However the `isPublic()` method will continue to return true. This allows you to distinguish whether
+  a method/property is explicitly or implicitly public and control the pretty printer output more precisely.
+
+* The `Stmt\Class_`, `Stmt\Interface_` and `Stmt\Trait_` nodes now inherit from `Stmt\ClassLike`, which provides a
+  `getMethods()` method. Previously this method was only available on `Stmt\Class_`.
+
+* Support including the `bootstrap.php` file multiple times.
+
+* Make documentation and tests part of the release tarball again.
+
+* Improve support for HHVM and PHP 7.
+
+### Added
+
+* Added support for PHP 7 return type declarations. This adds an additional `returnType` subnode to `Stmt\Function_`,
+  `Stmt\ClassMethod` and `Expr\Closure`.
+
+* Added support for the PHP 7 null coalesce operator `??`. The operator is represented by `Expr\BinaryOp\Coalesce`.
+
+* Added support for the PHP 7 spaceship operator `<=>`. The operator is represented by `Expr\BinaryOp\Spaceship`.
+
+* Added use builder.
+
+* Added global namespace support to the namespace builder.
+
+* Added a constructor flag to `NodeTraverser`, which disables cloning of nodes.
+
+Version 1.1.0 (2015-01-18)
+--------------------------
+
+* Methods that do not specify an explicit visibility (e.g. `function method()`) will now have the `MODIFIER_PUBLIC`
+  flag set. This also means that their `isPublic()` method will return true.
+
+* Declaring a property as abstract or final is now an error.
+
+* The `Lexer` and `Lexer\Emulative` classes now accept an `$options` array in their constructors. Currently only the
+  `usedAttributes` option is supported, which determines which attributes will be added to AST nodes. In particular
+  it is now possible to add information on the token and file positions corresponding to a node. For more details see
+  the [Lexer component](https://github.com/nikic/PHP-Parser/blob/master/doc/component/Lexer.markdown) documentation.
+
+* Node visitors can now return `NodeTraverser::DONT_TRAVERSE_CHILDREN` from `enterNode()` in order to skip all children
+  of the current node, for all visitors.
+
+* Added builders for traits and namespaces.
+
+* The class, interface, trait, function, method and property builders now support adding doc comments using the
+  `setDocComment()` method.
+
+* Added support for fully-qualified and namespace-relative names in builders. No longer allow use of name component
+  arrays.
+
+* Do not add documentation and tests to distribution archive files.
+
+Version 1.0.2 (2014-11-04)
+--------------------------
+
+* The `NameResolver` visitor now also resolves names in trait adaptations (aliases and precedence declarations).
+
+* Remove stray whitespace when pretty-printing trait adaptations that only change visibility.
+
+Version 1.0.1 (2014-10-14)
+--------------------------
+
+* Disallow `new` expressions without a class name. Previously `new;` was accidentally considered to be valid code.
+
+* Support T_ONUMBER token used by HHVM.
+
+* Add ability to directly pass code to the `php-parse.php` script.
+
+* Prevent truncation of `var_dump()` output in the `php-parse.php` script if XDebug is used.
+
+Version 1.0.0 (2014-09-12)
+--------------------------
+
+* [BC] Removed deprecated `Template` and `TemplateLoader` classes.
+
+* Fixed XML unserializer to properly work with new namespaced node names.
+
+Version 1.0.0-beta2 (2014-08-31)
+--------------------------------
+
+* [PHP 5.6] Updated support for constant scalar expressions to comply with latest changes. This means that arrays
+  and array dimension fetches are now supported as well.
+
+* [PHP 5.6] Direct array dereferencing of constants is supported now, i.e. both `FOO[0]` and `Foo::BAR[0]` are valid
+  now.
+
+* Fixed handling of special class names (`self`, `parent` and `static`) in the name resolver to be case insensitive.
+  Additionally the name resolver now enforces that special class names are only used as unqualified names, e.g. `\self`
+  is considered invalid.
+
+* The case of references to the `static` class name is now preserved. Previously `static` was always lowercased,
+  regardless of the case used in the source code.
+
+* The autoloader now only requires a file if it exists. This allows usages like
+  `class_exists('PhpParser\NotExistingClass')`.
+
+* Added experimental `bin/php-parse.php` script, which is intended to help exploring and debugging the node tree.
+
+* Separated the parser implemention (in `lib/PhpParser/ParserAbstract.php`) and the generated data (in
+  `lib/PhpParser/Parser.php`). Furthermore the parser now uses meaningful variable names and contains comments
+  explaining their usage.
+
+Version 1.0.0-beta1 (2014-03-27)

+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

+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]
+    project built on top of PHP-Parser instead.
+
+  * The `PrettyPrinterAbstract::pStmts()` method now emits a leading newline if the statement list is not empty.
+    Custom pretty printers should remove the explicit newline before `pStmts()` calls.
+
+    Old:
+
+    ```php
+    public function pStmt_Trait(PHPParser_Node_Stmt_Trait $node) {
+        return 'trait ' . $node->name
+             . "\n" . '{' . "\n" . $this->pStmts($node->stmts) . "\n" . '}';

UPGRADE-2.0.md

+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)`.

 Parsing
 -------
 
-In order to parse some source code you first have to create a `PhpParser\Parser` object (which
-needs to be passed a `PhpParser\Lexer` instance) and then pass the code (including `<?php` opening
-tags) to the `parse` method. If a syntax error is encountered `PhpParser\Error` is thrown, so this
-exception should be `catch`ed.
+In order to parse code, you first have to create a parser instance:
 
 ```php
-<?php
-$code = '<?php // some code';
+use PhpParser\ParserFactory;
+$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
+```
 
-$parser = new PhpParser\Parser(new PhpParser\Lexer);
+The factory accepts a kind argument, that determines how different PHP versions are treated:
+
+Kind | Behavior
+-----|---------
+`ParserFactory::PREFER_PHP7` | Try to parse code as PHP 7. If this fails, try to parse it as PHP 5.
+`ParserFactory::PREFER_PHP5` | Try to parse code as PHP 5. If this fails, try to parse it as PHP 7.
+`ParserFactory::ONLY_PHP7` | Parse code as PHP 7.
+`ParserFactory::ONLY_PHP5` | Parse code as PHP 5.
+
+Unless you have strong reason to use something else, `PREFER_PHP7` is a reasonable default.
+
+The `create()` method optionally accepts a `Lexer` instance as the second argument. Some use cases
+that require customized lexers are discussed in the [lexer documentation](component/Lexer.markdown).
+
+Subsequently you can pass PHP code (including the opening `<?php` tag) to the `parse` method in order to
+create a syntax tree. If a syntax error is encountered, an `PhpParser\Error` exception will be thrown:
+
+```php
+use PhpParser\Error;
+use PhpParser\ParserFactory;
+
+$code = '<?php // some code';
+$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7);
 
 try {
     $stmts = $parser->parse($code);
-} catch (PhpParser\Error $e) {
+    // $stmts is an array of statement nodes
+} catch (Error $e) {
     echo 'Parse Error: ', $e->getMessage();
 }
 ```
 
-The `parse` method will return an array of statement nodes (`$stmts`).
-
-### Emulative lexer
-
-Instead of `PhpParser\Lexer` one can also use `PhpParser\Lexer\Emulative`. This class will emulate tokens
-of newer PHP versions and as such allow parsing PHP 5.5 on PHP 5.2, for example. So if you want to parse

-Templates
----------
-
-> **DEPRECATED**: This feature is deprecated and will be removed in PHP-Parser 1.0.
-
-Additionally it is possible to generate code from reusable templates.
-
-As an example consider the following template, which defines a general getter/setter skeleton in terms of a property
-`__name__` and its `__type__`:
-
-```php
-<?php
-
-class GetterSetterTemplate
-{
-    /**
-     * @var __type__ The __name__
-     */
-    protected $__name__;
-
-    /**
-     * Gets the __name__.
-     *
-     * @return __type__ The __name__
-     */
-    public function get__Name__() {
-        return $this->__name__;
-    }
-
-    /**
-     * Sets the __name__.
-     *
-     * @param __type__ $__name__ The new __name__
-     */
-    public function set__Name__($__name__) {
-        $this->__name__ = $__name__;
-    }
-}
-```
-
-Using this template we can easily create a class with multiple properties and their respective getters and setters:
-
-```php
-<?php
-
-// $templateString contains the above template
-$template = new PhpParser\Template($parser, $templateString);
-
-// We only have to specify the __name__ placeholder, as the
-// capitalized __Name__ placeholder is automatically created
-$properties = [
-    ['name' => 'title',     'type' => 'string'],
-    ['name' => 'body',      'type' => 'string'],
-    ['name' => 'author',    'type' => 'User'],
-    ['name' => 'timestamp', 'type' => 'DateTime'],
-];
-
-$class = $factory->class('BlogPost')->implement('Post');
-
-foreach ($properties as $propertyPlaceholders) {
-    $stmts = $template->getStmts($propertyPlaceholders);
-
-    $class->addStmts(
-        // $stmts contains all statements from the template. So [0] fetches the class statement
-        // and ->stmts retrieves the methods.
-        $stmts[0]->stmts
-    );
-}
-
-echo $prettyPrinter->prettyPrint(array($class->getNode()));
-```
-
-The result would look roughly like this:
-
-```php

-
-class BlogPost implements Post

-     */
-    public function getAuthor()
-    {
-        return $this->author;
-    }
-
-    /**
-     * Sets the author.
-     *
-     * @param User $author The new author
-     */
-    public function setAuthor($author)
-    {
-        $this->author = $author;
-    }
-
-    /**
-     * Gets the timestamp.
-     *
-     * @return DateTime The timestamp
-     */
-    public function getTimestamp()
-    {
-        return $this->timestamp;
-    }
-
-    /**
-     * Sets the timestamp.
-     *
-     * @param DateTime $timestamp The new timestamp
-     */
-    public function setTimestamp($timestamp)
-    {
-        $this->timestamp = $timestamp;
-    }
-}
-```
-
-When using multiple templates it is easier to manage them on the filesystem. They can be loaded using the
-`TemplateLoader`:
-
-```php
-<?php
-
-// We'll store our templates in ./templates and give them a .php suffix
-$loader = new PhpParser\TemplateLoader($parser, './templates', '.php');
-
-// loads ./templates/GetterSetter.php
-$getterSetterTemplate = $loader->load('GetterSetter');
-
-// loads ./templates/Collection.php
-$collectionTemplate = $loader->load('Collection');
-
-// The use of a suffix is optional. The following code for example is equivalent:
-$loader = new PhpParser\TemplateLoader($parser, './templates');
-
-// loads ./templates/GetterSetter.php
-$getterSetterTemplate = $loader->load('GetterSetter.php');
-
-// loads ./templates/Collection.php
-$collectionTemplate = $loader->load('Collection.php');
-```

+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);
+} else {
+    echo $e->getMessage();
+}
+```
+
+Both line numbers and column numbers are 1-based. EOF errors will be located at the position one past the end of the
+file.
+
+Error recovery
+--------------
+
+> **EXPERIMENTAL**
+
+By default the parser will throw an exception upon encountering the first error during parsing. An alternative mode is
+also supported, in which the parser will remember the error, but try to continue parsing the rest of the source code.
+
+To enable this mode the `throwOnError` parser option needs to be disabled. Any errors that occurred during parsing can
+then be retrieved using `$parser->getErrors()`. The `$parser->parse()` method will either return a partial syntax tree
+or `null` if recovery fails.
+
+A usage example:
+
+```php
+$parser = (new PhpParser\ParserFactory)->create(PhpParser\ParserFactory::PREFER_PHP7, null, array(
+    'throwOnError' => false,
+));
+
+$stmts = $parser->parse($code);
+$errors = $parser->getErrors();
+
+foreach ($errors as $error) {
+    // $error is an ordinary PhpParser\Error
+}
+
+if (null !== $stmts) {
+    // $stmts is a best-effort partial AST
+}
+```
+
+The error recovery implementation is experimental -- it currently won't be able to recover from many types of errors.

 `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.
 
-A lexer has to define the following public interface:
+This documentation discusses options available for the default lexers and explains how lexers can be extended.
 
-    startLexing($code);
-    getNextToken(&$value = null, &$startAttributes = null, &$endAttributes = null);
-    handleHaltCompiler();
+Lexer options
+-------------
 
-startLexing
------------
-
-The `startLexing` method is invoked when the `parse()` method of the parser is called. It's argument will be whatever
-was passed to the `parse()` method.
-
-Even though `startLexing` is meant to accept a source code string, you could for example overwrite it to accept a file:
+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
-<?php
+$lexer = new PhpParser\Lexer(array(
+    'usedAttributes' => array(
+        'comments', 'startLine', 'endLine'
+    )
+));
+```
 
-class FileLexer extends PhpParser\Lexer {
-    public function startLexing($fileName) {
-        if (!file_exists($fileName)) {
-            throw new InvalidArgumentException(sprintf('File "%s" does not exist', $fileName));
+The attributes used in this example match the default behavior of the lexer. The following attributes are supported:
+
+ * `comments`: Array of `PhpParser\Comment` or `PhpParser\Comment\Doc` instances, representing all comments that occurred
+   between the previous non-discarded token and the current one. Use of this attribute is required for the
+   `$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, $node));
         }
-
-        parent::startLexing(file_get_contents($fileName));
     }
 }
 
-$parser = new PhpParser\Parser(new FileLexer);
+$lexer = new PhpParser\Lexer(array(
+    'usedAttributes' => array(
+        'comments', 'startLine', 'endLine', 'startTokenPos', 'endTokenPos'
+    )
+));
+$parser = (new PhpParser\ParserFactory)->create(PhpParser\ParserFactory::PREFER_PHP7, $lexer);
 
-var_dump($parser->parse('someFile.php'));
-var_dump($parser->parse('someOtherFile.php'));
+$visitor = new MyNodeVisitor();
+$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();
+}
 ```
 
-getNextToken
-------------
+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).
 
-`getNextToken` returns the ID of the next token and sets some additional information in the three variables which it
-accepts by-ref. If no more tokens are available it has to return `0`, which is the ID of the `EOF` token.
+Lexer extension
+---------------
 
-The first by-ref variable `$value` should contain the textual content of the token. It is what will be available as `$1`
-etc in the parser.
+A lexer has to define the following public interface:
+
+    void startLexing(string $code);
+    array getTokens();
+    string handleHaltCompiler();
+    int getNextToken(string &$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 `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

+
+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 `$startAttributes` from the first token which is part of the
@@ -54,61 +122,28 @@ node and the `$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.
 
-By default the lexer creates the attributes `startLine`, `comments` (both part of `$startAttributes`) and `endLine`
-(part of `$endAttributes`).
-
-If you don't want all these attributes to be added (to reduce memory usage of the AST) you can simply remove them by
-overriding the method:
+An application of custom attributes is storing the original formatting of literals: The parser does not retain
+information about the formatting of integers (like decimal vs. hexadecimal) or strings (like used quote type or used
+escape sequences). This can be remedied by storing the original value in an attribute:
 
 ```php
-<?php
+use PhpParser\Lexer;
+use PhpParser\Parser\Tokens;
 
-class LessAttributesLexer extends PhpParser\Lexer {
+class KeepOriginalValueLexer extends Lexer // or Lexer\Emulative
+{
     public function getNextToken(&$value = null, &$startAttributes = null, &$endAttributes = null) {
         $tokenId = parent::getNextToken($value, $startAttributes, $endAttributes);
 
-        // only keep startLine attribute
-        unset($startAttributes['comments']);
-        unset($endAttributes['endLine']);
-
-        return $tokenId;
-    }
-}
-```
-
-You can obviously also add additional attributes. E.g. in conjunction with the above `FileLexer` you might want to add
-a `fileName` attribute to all nodes:
-
-```php
-<?php
-
-class FileLexer extends PhpParser\Lexer {
-    protected $fileName;
-
-    public function startLexing($fileName) {
-        if (!file_exists($fileName)) {
-            throw new InvalidArgumentException(sprintf('File "%s" does not exist', $fileName));
+        if ($tokenId == Tokens::T_CONSTANT_ENCAPSED_STRING // non-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;
         }
 
-        $this->fileName = $fileName;
-        parent::startLexing(file_get_contents($fileName));
-    }
-
-    public function getNextToken(&$value = null, &$startAttributes = null, &$endAttributes = null) {
-        $tokenId = parent::getNextToken($value, $startAttributes, $endAttributes);
-
-        // we could use either $startAttributes or $endAttributes here, because the fileName is always the same
-        // (regardless of whether it is the start or end token). We choose $endAttributes, because it is slightly
-        // more efficient (as the parser has to keep a stack for the $startAttributes).
-        $endAttributes['fileName'] = $this->fileName;
