Locating Includes for Rewriting

Clang Frontend
1

I am working on a source-to-source translator plugin for clang. Currently, I rewrite both the main file and some included files to new files in the process. Given this, I wanted to automatically rewrite the includes of rewritten header files.

In the RewriteObjC class something similar is done where they rewrite #imports to #includes. Theeir method of locating the imports is by manually traversing the buffer character by character, which works fine but in my case would be more complex. Therefore, I was wondering if there is any portion of clang or llvm that may aid me in locating the includes?

Thanks,
Gabriel

You can derive of the PPCallbacks-class and overwrite the InclusionDirective- or FileChanged-method to get informed about inclusions.

Then, add an instance of your class per addPPCallbacks to your preprocessor.

That’ll work nicely. Thanks!
