PHP-Parser 4.13.1

Fixed

• Support reserved keywords as enum cases.
• Support array unpacking in constant expression evaluator.

PHP-Parser 4.13.0

This release features full PHP 8.1 support.

Added

• [PHP 8.1] Added support for intersection types using a new IntersectionType node. Additionally a ComplexType parent class for NullableType, UnionType and IntersectionType has been added.
• [PHP 8.1] Added support for explicit octal literals.
• [PHP 8.1] Added support for first-class callables. These are represented using a call whose first argument is a VariadicPlaceholder. The representation is intended to be forward-compatible with partial function application, just like the PHP feature itself. Call nodes now extend from Expr\CallLike, which provides an isFirstClassCallable() method to determine whether a placeholder id present. getArgs() can be used to assert that the call is not a first-class callable and returns Arg[] rather than array<Arg|VariadicPlaceholder>.

Fixed

• Multiple modifiers for promoted properties are now accepted. In particular this allows something like public readonly for promoted properties.
• Formatting-preserving pretty printing for comments in array literals has been fixed.

PHP-Parser 4.12.0

Added

• [PHP 8.1] Added support for readonly properties (through a new MODIFIER_READONLY).
• [PHP 8.1] Added support for final class constants.

Fixed

• Fixed compatibility with PHP 8.1. & tokens are now canonicalized to the T_AMPERSAND_FOLLOWED_BY_VAR_OR_VARARG and T_AMPERSAND_NOT_FOLLOWED_BY_VAR_OR_VARARG tokens used in PHP 8.1. This happens unconditionally, regardless of whether the emulative lexer is used.

PHP-Parser 4.11.0

Added

• BuilderFactory::args() now accepts named arguments.
• BuilderFactory::attribute() has been added.
• An addAttribute() method accepting an Attribute or AttributeGroup has been added to all builders that accept attributes, such as Builder\Class_.

Fixed

• NameResolver now handles enums.
• PrettyPrinter now prints backing enum type.
• Builder methods for types now property handle never type.

PHP-Parser 4.10.5

Added

• [PHP 8.1] Added support for enums. These are represented using the Stmt\Enum_ and Stmt\EnumCase nodes.
• [PHP 8.1] Added support for never type. This type will now be returned as an Identifier rather than Name.
• Added ClassConst builder.

Changed

• Non-UTF-8 code units in strings will now be hex-encoded.

Fixed

• Fixed precedence of arrow functions.

PHP-Parser 4.10.4

Fixed

• Fixed position information for variable-variables (#741).
• Fixed position information for traits/interfaces preceded by if statement (#738).

PHP-Parser 4.10.3

Fixed

• Fixed formatting-preserving pretty printing for "{$x}".
• Ternary expressions are now treated as non-associative in the pretty printer, in order to generate code that is compatible with the parentheses requirement introduced in PHP 8.
• Removed no longer necessary error_clear_last() call in lexer, which may interfere with fatal error handlers if invoked during shutdown.

PHP-Parser 4.10.2

Fixed

• Fixed check for token emulation conflicts with other libraries.

PHP-Parser 4.10.1

Added

• Added support for recovering from a missing semicolon after a property or class constant declaration.

Fixed

• Fix spurious whitespace in formatting-preserving pretty printer when both removing and adding elements at the start of a list.
• Fix incorrect case-sensitivity in keyword token emulation.

PHP-Parser 4.10.0

Added

• [PHP 8.0] Added support for attributes. These are represented using a new AttributeGroup node containing Attribute nodes. A new attrGroups subnode is available on all node types that support attributes, i.e. Stmt\Class_, Stmt\Trait_, Stmt\Interface_, Stmt\Function_, Stmt\ClassMethod, Stmt\ClassConst, Stmt\Property, Expr\Closure, Expr\ArrowFunction and Param.
• [PHP 8.0] Added support for nullsafe properties inside interpolated strings, in line with an upstream change.

Fixed

• Improved compatibility with other libraries that use forward compatibility defines for PHP tokens.
