It handles some partial and illegal code, producing best-effort partial syntax tree. Its purpose is to simplify static code analysis and manipulation. It's error reporting is not complete though, i.e. it may silently accept illegal PHP input. As this is just a parser replacement for [PHP Parser](https://github.com/nikic/PHP-Parser), go there for actual documentation. Installation ------------ [](#installation) The preferred installation method is [composer](https://getcomposer.org): ``` php composer.phar require tsufeki/php-lenient-parser ``` Usage ----- [](#usage) Use the factory to get an instance of parser: ``` $parser = (new LenientParserFactory())->create(); ``` Or provide your own lexer and options (no options are supported at the moment though): ``` $parser = (new LenientParserFactory())->create(LenientParserFactory::ONLY_PHP7, $lexer, $options); ``` Created parser is a drop-in replacement for `php-parser`. Do not instantiate `LenientParser` directly, use the factory. Info ---- [](#info) At the moment parsing of PHP 5 is not supported, only PHP 7. Internally, the parser is implemented as a Pratt parser (also called "Top down operator precedence parser"). License ------- [](#license) Same as `php-parser`, BSD - see [LICENCE](LICENSE). Test suite and CLI script (below `bin/`, `test/` and `test_old/`) are borrowed from `php-parser` and modified. ### Health Score 29 — LowBetter than 57% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity17 Limited adoption so far Community23 Small or concentrated contributor base Maturity52 Maturing project, gaining track record Bus Factor1 Top contributor holds 80.4% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
