Version 0.9.5-dev
|
||||
Version 1.0.0-dev
|
||||
-----------------
|
||||
|
||||
* [BC] 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.
|
||||
|
||||
* [BC] 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.
|
||||
|
||||
However, code performing dispatch operations on `Node::getType()` may be affected by some of the name changes. For
|
||||
example a `+` node will now return type `Expr_BinaryOp_Plus` instead of `Expr_Plus`. In particular this may affect
|
||||
custom pretty printers.
|
||||
|
||||
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)
|
||||
|
||||
* [PHP 5.6] Added support for the power operator `**` (node `Expr\BinaryOp\Pow`) and the compound power assignment
|
||||
operator `**=` (node `Expr\AssignOp\Pow`).
|
||||
|
||||
* [PHP 5.6] Added support for variadic functions: `Param` nodes now have `variadic` as a boolean subnode.
|
||||
|
||||
* [PHP 5.6] Added support for argument unpacking: `Arg` nodes now have `unpack` as a boolean subnode.
|
||||
|
||||
* [PHP 5.6] Added support for aliasing of functions and constants. `Stmt\Use_` nodes now have an integral `type`
|
||||
subnode, which is one of `Stmt\Use_::TYPE_NORMAL` (`use`), `Stmt\Use_::TYPE_FUNCTION` (`use function`) or
|
||||
`Stmt\Use_::TYPE_CONSTANT` (`use const`).
|
||||
|
||||
The `NameResolver` now also supports resolution of such aliases.
|
||||
|
||||
* [PHP 5.6] Added support for constant scalar expressions. This means that certain expressions are now allowed as the
|
||||
initializer for constants, properties, parameters, static variables, etc.
|
||||
|
||||
* [BC] Improved pretty printing of empty statements lists, which are now printed as `{\n}` instead of `{\n \n}`.
|
||||
This changes the behavior of the protected `PrettyPrinterAbstract::pStmts()` method, so custom pretty printing code
|
||||
making use it of may need to be adjusted.
|
||||
|
||||
* Changed the order of some subnodes to be consistent with their order in the sour code. For example `Stmt\If->cond`
|
||||
will now appear before `Stmt\If->stmts` etc.
|
||||
|
||||
* Added `Scalar\MagicConstant->getName()`, which returns the name of the magic constant (e.g. `__CLASS__`).
|
||||
|
||||
**The following changes are also included in 0.9.5-dev**:
|
||||
|
||||
* [BC] Deprecated `PHPParser_Template` and `PHPParser_TemplateLoader`. This functionality does not belong in the main project
|
||||
and - as far as I know - nobody is using it.
|
||||
|
||||
* Add `NodeTraverser::removeVisitor()` method, which removes a visitor from the node traverser. This also modifies the
|
||||
corresponding `NodeTraverserInterface`.
|
||||
|
||||
* Deprecated `PHPParser_Template` and `PHPParser_TemplateLoader`. This functionality does not belong in the main project
|
||||
and - as far as I know - nobody is using it.
|
||||
|
||||
* Fix alias resolution in `NameResolver`: Class names are now correctly handled as case-insensitive.
|
||||
|
||||
* The undefined variable error, which is used to the lexer to reset the error state, will no longer interfere with
|
||||
custom error handlers.
|
||||
|
||||
Version 0.9.4 (25.08.2013)
|
||||
--------------------------
|
||||
* [PHP 5.5] Add support for `ClassName::class`. This is parsed as an `Expr_ClassConstFetch` with `'class'` being the
|
||||
constant name.
|
||||
---
|
||||
|
||||
* Syntax errors now include information on expected tokens and mimic the format of PHP's own (pre 5.4) error messages.
|
||||
Example:
|
||||
**This changelog only includes changes from the 1.0 series. For older changes see the [0.9 series changelog][1].**
|
||||
|
||||
Old: Unexpected token T_STATIC on line 1
|
||||
New: Syntax error, unexpected T_STATIC, expecting T_STRING or T_NS_SEPARATOR or '{'
|
||||
|
||||
* `PHPParser_PrettyPrinter_Zend` was renamed to `PHPParser_PrettyPrinter_Default` as the default pretty printer only
|
||||
very loosely applies the Zend Coding Standard. The class `PHPParser_PrettyPrinter_Zend` extends
|
||||
`PHPParser_PrettyPrinter_Default` to maintain backwards compatibility.
|
||||
|
||||
* The pretty printer now prints namespaces in semicolon-style if possible (i.e. if the file does not contain a global
|
||||
namespace declaration).
|
||||
|
||||
* Added `prettyPrintFile(array $stmts)` method which will pretty print a file of statements including the opening
|
||||
`<?php` tag if it is required. Use of this method will also eliminate the unnecessary `<?php ?>` at the start and end
|
||||
of files using inline HTML.
|
||||
|
||||
* There now is a builder for interfaces (`PHPParser_Builder_Interface`).
|
||||
|
||||
* An interface for the node traversation has been added: `PHPParser_NodeTraverserInterface`
|
||||
|
||||
* Fix pretty printing of `include` expressions (precedence information was missing).
|
||||
|
||||
* Fix "undefined index" notices when generating the expected tokens for a syntax error.
|
||||
|
||||
* Improve performance of `PrettyPrinter` construction by no longer using the `uniqid()` function.
|
||||
|
||||
Version 0.9.3 (22.11.2012)
|
||||
--------------------------
|
||||
|
||||
* [BC] As `list()` in `foreach` is now supported the structure of list assignments changed:
|
||||
|
||||
1. There is no longer a dedicated `AssignList` node; instead a normal `Assign` node is used with a `List` as `var`.
|
||||
2. Nested lists are now `List` nodes too, instead of just arrays.
|
||||
|
||||
* [BC] As arbitrary expressions are allowed in `empty()` now its subnode was renamed from `var` to `expr`.
|
||||
|
||||
* [BC] The protected `pSafe()` method in `PrettyPrinterAbstract` was renamed to `pNoIndent()`.
|
||||
|
||||
* [PHP 5.5] Add support for arbitrary expressions in `empty()`.
|
||||
|
||||
* [PHP 5.5] Add support for constant array / string dereferencing.
|
||||
Examples: `"foo"[2]`, `[1, 2, 3][2]`
|
||||
|
||||
* [PHP 5.5] Add support for `yield` expressions. This adds a new `Yield` expression type, with subnodes `key` and
|
||||
`value`.
|
||||
|
||||
* [PHP 5.5] Add support for `finally`. This adds a new `finallyStmts` subnode to the `TryCatch` node. If there is no
|
||||
finally clause it will be `null`.
|
||||
|
||||
* [PHP 5.5] Add support for `list()` destructuring of `foreach` values.
|
||||
Example: `foreach ($coords as list($x, $y)) { ... }`
|
||||
|
||||
* Improve pretty printing of expressions by printing less unnecessary parentheses. In particular concatenations are now
|
||||
printed as `$a . $b . $c . $d . $e` rather than `$a . ($b . ($c . ($d . $e)))`. This is implemented by taking operator
|
||||
associativity into account. New protected methods added to the pretty printer are `pPrec()`, `pInfixOp()`,
|
||||
`pPrefixOp()` and `pPostfixOp()`. This also fixes an issue with extraneous parentheses in closure bodies.
|
||||
|
||||
* Fix formatting of fall-through `case` statements in the Zend pretty printer.
|
||||
|
||||
* Fix parsing of `$foo =& new Bar`. It is now properly parsed as `AssignRef` (instead of `Assign`).
|
||||
|
||||
* Fix assignment of `$endAttributes`. Sometimes the attributes of the token right after the node were assigned, rather
|
||||
than the attributes of the last token in the node.
|
||||
|
||||
* `rebuildParser.php` is now designed to be run from the command line rather than from the browser.
|
||||
|
||||
Version 0.9.2 (07.07.2012)
|
||||
--------------------------
|
||||
|
||||
* Add `Class->getMethods()` function, which returns all methods contained in the `stmts` array of the class node. This
|
||||
does not take inherited methods into account.
|
||||
|
||||
* Add `isPublic()`, `isProtected()`, `isPrivate()`. `isAbstract()`, `isFinal()` and `isStatic()` accessors to the
|
||||
`ClassMethod`, `Property` and `Class` nodes. (`Property` and `Class` obviously only have the accessors relevant to
|
||||
them.)
|
||||
|
||||
* Fix parsing of new expressions in parentheses, e.g. `return(new Foo);`.
|
||||
|
||||
* [BC] Due to the below changes nodes now optionally accept an `$attributes` array as the
|
||||
last parameter, instead of the previously used `$line` and `$docComment` parameters.
|
||||
|
||||
* Add mechanism for adding attributes to nodes in the lexer.
|
||||
|
||||
The following attributes are now added by default:
|
||||
|
||||
* `startLine`: The line the node started in.
|
||||
* `endLine`: The line the node ended in.
|
||||
* `comments`: An array of comments. The comments are instances of `PHPParser_Comment`
|
||||
(or `PHPParser_Comment_Doc` for doc comments).
|
||||
|
||||
The methods `getLine()` and `setLine()` still exist and function as before, but internally
|
||||
operator on the `startLine` attribute.
|
||||
|
||||
`getDocComment()` also continues to exist. It returns the last comment in the `comments`
|
||||
attribute if it is a doc comment, otherwise `null`. As `getDocComment()` now returns a
|
||||
comment object (which can be modified using `->setText()`) the `setDocComment()` method was
|
||||
removed. Comment objects implement a `__toString()` method, so `getDocComment()` should
|
||||
continue to work properly with old code.
|
||||
|
||||
* [BC] Use inject-once approach for lexer:
|
||||
|
||||
Now the lexer is injected only once when creating the parser. Instead of
|
||||
|
||||
$parser = new PHPParser_Parser;
|
||||
$parser->parse(new PHPParser_Lexer($code));
|
||||
$parser->parse(new PHPParser_Lexer($code2));
|
||||
|
||||
you write:
|
||||
|
||||
$parser = new PHPParser_Parser(new PHPParser_Lexer);
|
||||
$parser->parse($code);
|
||||
$parser->parse($code2);
|
||||
|
||||
* Fix `NameResolver` visitor to also resolve class names in `catch` blocks.
|
||||
|
||||
Version 0.9.1 (24.04.2012)
|
||||
--------------------------
|
||||
|
||||
* Add ability to add attributes to nodes:
|
||||
|
||||
It is now possible to add attributes to a node using `$node->setAttribute('name', 'value')` and to retrieve them using
|
||||
`$node->getAttribute('name' [, 'default'])`. Additionally the existance of an attribute can be checked with
|
||||
`$node->hasAttribute('name')` and all attributes can be returned using `$node->getAttributes()`.
|
||||
|
||||
* Add code generation features: Builders and templates.
|
||||
|
||||
For more infos, see the [code generation documentation][1].
|
||||
|
||||
* [BC] Don't traverse nodes merged by another visitor:
|
||||
|
||||
If a NodeVisitor returns an array of nodes to merge, these will no longer be traversed by all other visitors. This
|
||||
behavior only caused problems.
|
||||
|
||||
* Fix line numbers for some list structures.
|
||||
* Fix XML unserialization of empty nodes.
|
||||
* Fix parsing of integers that overflow into floats.
|
||||
* Fix emulation of NOWDOC and binary floats.
|
||||
|
||||
