Deprecated, moved to Rector

Better PhpDoc Parser

Wrapper around phpstan/phpdoc-parser that adds format preserving printer.

When do We Need Format Preserving Printer?

Original code

/**
 * @param   string   $name
 * @param   string   $surname
 * @return  bool
  */

Printed by PHPStan PhpDocParser :x:

/**
 * @param string $name
 * @param string $surname
 * @return bool
 */

Printed by Better PhpDocParser :+1:

/**
 * @param   string   $name
 * @param   string   $surname
 * @return  bool
 */

Symplify\CodingStandard and Rector need to modify docblock and put it back in correct format. Other packages often put own spacing, or formats of specific tags.

This package preserve original spacing.

Thanks for inspiration in Format Preserving Printer feature in nikic/php-parser.
