PHP-Parser 5.0.0-alpha2

on GitHub

See UPGRADE-5.0 for detailed migration instructions.

Added

• [PHP 8.3] Added support for dynamic class constant fetch.
• Added many additional type annotations. PhpStan is now used.
• Added a fuzzing target for PHP-Fuzzer, which was how a lot of pretty printer bugs were found.
• Added isPromoted(), isPublic(), isProtected(), isPrivate() and isReadonly() methods on Param.
• Added support for class constants in trait builder.
• Added PrettyPrinter interface.
• Added support for formatting preservation when toggling static modifiers.
• The php-parse binary now accepts - as the file name, in which case it will read from stdin.

Fixed

• The pretty printer now uses a more accurate treatment of unary operator precedence, and will only wrap them in parentheses if required. This allowed fixing a number of other precedence related bugs.
• The pretty printer now respects the precedence of clone, throw and arrow functions.
• The pretty printer no longer unconditionally wraps yield in parentheses, unless the target version is set to older than PHP 7.0.
• Fixed formatting preservation for alternative elseif/else syntax.
• Fixed checks for when it is safe to print strings as heredoc/nowdoc to accommodate flexible doc string semantics.
• The pretty printer now prints parentheses around new/instanceof operands in all required situations.
• Similar, differences in allowed expressions on the LHS of -> and :: are now taken into account.
• Fixed various cases where \r at the end of a doc string could be incorrectly merged into a CRLF sequence with a following \n.
• __halt_compiler is no longer recognized as a semi-reserved keyword, in line with PHP behavior.
• <?= is no longer recognized as a semi-reserved keyword.
• Fix handling of very large overflowing \u escape sequences.

Removed

• Removed deprecated Error constructor taking a line number instead of an attributes array.
