A curated list of amazingly awesome tools, articles and books about abstract syntax tree in PHP world. From parsing PHP, through traversing templates and configs through automated upgrades.

Note: this repository should not be list of tools that run on nikic/php-parser, but rather tools that main feature developer actually works with is abstract syntax tree.

• Good example - PHPStan, because you work with PHP nodes in every single rule.
• Bad example - Twig, it has structure in AST and has node visitors, but marginal number of developers use it. It's main feature is template compilation, filters and functions.
