This project uses Microsoft/tolerant-php-parser to generate a tree with error tolerance, then converts from that tree to ast\Node from php-ast

This release supports AST version 70.


Using it as a slow substitute for php-ast

Using it as an error-tolerant substitute for php-ast (e.g. for use in IDEs)

  • There are currently two modes: omitting errors and adding placeholders (e.g. __INCOMPLETE_VARIABLE__).
  • Omitting errors only handles some common cases that come up while editing a file.
  • Placeholders may change in the future.
  • tests/ASTConverter/ErrorTolerantConversionTest.php
  • Phan's Language Server uses this code to do that.

Running unit tests

To run unit tests, you must install nikic/php-ast 1.0.1+ (for the expected results to be created). You must also run composer install if you haven't already done so.

  • For php 7.4, php-ast 1.0.3+ must be installed.
  • Then run vendor/bin/phpunit

Possible Future Enhancements

  • Adding a mode to never accept invalid PHP (for completeness)
