ircmaxell/php-c-parser
Parse C source files into an AST in PHP (PHP 8.4+), including preprocessing resolution. Use a Context to set #define values (ints, strings, identifiers) before parsing. Great for analysis tools, code inspection, and experimentation.
This is a library to parse C code into an AST. Using PHP.
Yes, this is an extraordinarily bad idea...
$parser = new PHPCParser\CParser;
$ast = $parser->parse('path/to/file');
Note that pre-processor directives are all correctly resolved.
If you need to set a pre-processor define, you can use a context;
$parser = new PHPCParser\CParser;
$context = new PHPCParser\Context;
// #define A 42
$context->defineInt('A', 42);
// #define B "testing"
$context->defineString('B', "testing");
// #define C testing
$context->defineIdentifier('C', 'testing');
// etc...
$ast = $parser->parse('path/to/file', $context);
And that's all there is to it (until it is working that is...)...
$ clang -cc1 -ast-dump test.c
