Hi, recently I've touched .idl files in http://cgit.freedesktop.org/libreoffice/core/commit/?id=b7c41f1d1fcabc8f4abc670d5a18546a117b540a http://cgit.freedesktop.org/libreoffice/core/commit/?id=1f77f1ac177521698ee7c978f218127cb5840046 And I wonder if there is an easy way how to tell, they can be removed. For files added with gb_UnoApi_add_idlfile_noheader, one probably have to grep in the code. But maybe for files in gb_UnoApi_add_idlfile_nohdl, it is possible to know they are unused if there is no #include foo.hpp ? And something similar for gb_UnoApi_add_idlfile ? Is there something better than check each and every .idl file ? I think we would find few(many?) unused ones. Thanks, Matus
