This repo contains the localization files of Crane and the libCrane.h header to use it's functionality from other tweaks (Not supported on Crane Lite!). Crane is a commercial software available on Havoc.
Run install_libcrane.sh in the libCrane directory to install the libcrane tbd's into theos.
Afterwards you can add libcrane to your makefile as follows:
<YOUR_PROJECT>_LIBRARIES += crane
Then copy libCrane.h into your project and include it, read the header to see what methods are available.
Some APIs use XPC to communicate with cranehelperd so if you are trying to use libCrane from a sandboxed process, you will have to use libSandy to gain access to the com.opa334.cranehelperd.xpc mach service.
