Regarding pre-processing, I feed the result of `clang -E` to the code-generator. Since I use a unity build (single translation unit), it works out fine. In fact, the parser treats pre-processor directives as comments (to work around #line and `-dD`, etc.) Regarding external and intrusive, I used to do it in the intrusive way but found it too limiting. Here, I not only generate code but can also (potentially) add whole new extensions to the language. This was the reason I wrote a new parser instead of just using libclang's JSON AST dump. Well, that and the fact that libclang is a multi-MB dependency while my parser is ~3000 lines of C code. |
