Hi, I'm trying to adopt Wave as my custom preprocessor for a project. So far, things work fine, but there is one problem with Wave: I need to override all I/O functions, in particular, reading from files and opening files. Reading is easily changed by the input policy, but I couldn't find a way to register an include handler hook. There's found_include_directive, but nothing that allows me to get in-between wave and the filesystem. In my case, I on-demand construct some data which I want to be able to #include (i.e. #include <generated>) and some files are stored in resources/compressed files (#include <zip/file.h>). My include handler can open them, but how can I tell Wave to ask my include handler whether it can find a file instead of using boost::filesystem? Cheers, Anteru
