It allows easy traversing and analyzing of an abstract syntax tree of a c / c++ file. Unfortunately PHP FFI does not currently support Struct By Value as parameter or return value in function calls. That is why a c based wrapper is provided for libclang itself, which can then be bound via FFI. This wrapper must be compiled before use. The wrapper is taken from [dart ffigen](https://github.com/dart-lang/ffigen) and has been slightly extended. Expect breaking changes along all 0.\* pre-releases. Requirements ------------ [](#requirements) - PHP >= 7.4 - FFI extension enabled - LLVM >= 9 with clang and libclang-dev Quick Start ----------- [](#quick-start) Install llvm with clang ... ... on macOS (see ) ``` brew install llvm@11 ``` ... on Debian / Ubuntu (see ) ``` apt-get update; \ apt-get install wget lsb-release software-properties-common ca-certificates gnupg; \ wget -q https://apt.llvm.org/llvm.sh; \ chmod +x llvm.sh; \ sudo ./llvm.sh 11; \ apt-get install libclang-11-dev; ``` Install in your project ``` composer require klitsche/clang-ffi ``` Add to composer.json (this will trigger compilation of wrapped libclang library) ``` "scripts": { "post-autoload-dump": "Klitsche\\Clang\\FFI\\libclang\\Compiler::run", }, ``` Dump autoload to trigger compilation ``` composer dump-autoload ``` Run examples ------------ [](#run-examples) Checkout & prepare ``` git clone https://github.com/klitsche/clang-ffi.git; \ cd clang-ffi; \ docker-compose build; ``` Print parsed file ``` docker-compose run --rm php74 php examples/print.php ``` Collect and dump simplified AST nodes as json ``` docker-compose run --rm php74 php examples/json.php ``` Dump found issues during parsing ``` docker-compose run --rm php74 php examples/issues.php ``` Todos ----- [](#todos) - Add ffigen - Add multiversion support for llvm >9 (some const values are different) - Add documentation - Add support for Windows License ------- [](#license) See [LICENSE.md](LICENSE.md) for details.
