Question regarding preprocessor directives
Hello,
I am thinking about using cplusplus to write some personal source analysis and transformation tools. The first one i want to implement is a simple file dependency analyzer.
Is this possible? At first glance it doesn't appear that the include directives are preserved. Am i missing something?
For me the value of your project is in a lighter libclang (like about 50 tones lighter) for analysis purposes.
Hi @JakeSays,
Thanks for showing interest in this project.
I'm afraid the C++20 frontend is not ready for writing such tools. I recently started to work on the type checker and the semantic passes required to correctly parse modern C++ code. As soon as I'm done with the type checker I will try to expose a set of APIs to use the preprocessor, the parser and the code model in C++ and JS apps.
Ah ok. I thought this was a continuation of the one that was used in qt creator. Is that version available somewhere? I looked for it in the creator repo but I couldn't find it.
Also I would be interested in writing a c# binding for this project when you get to that point.
Yeah, modern C++ is considerably different than the versions of C++ I implemented in the past so I thought it was easier to start from scratch.
You can find the Qt Creator C++ parser in these two directories but I don't know if you can still compile it as a standalone library.
https://github.com/qt-creator/qt-creator/tree/master/src/libs/3rdparty/cplusplus https://github.com/qt-creator/qt-creator/tree/master/src/libs/cplusplus
I see there is a file named:
https://github.com/robertoraggi/cplusplus/blob/main/src/cxx/preprocessor.cc
which I see is a preprocessor.
Good work!
@asmwarrior yes, the preprocessor is almost complete but I still need to add APIs to abstract the file system access and configure the predefined macros and the system include paths.
