C++ client to kRPC for communicate with Kerbal Space Program (KSP)

kRPCI

kRPCI is a C++ client to kRPC for communicating with Kerbal Space Program (KSP).

Using the Client Library

• Copy the .cc, .cpp and .h files in src to your project directory
• Instantiate a KRPCI client object and use the generated functions in krpci_generated.cpp
• See krpci_test.cpp for a concrete example

Updating kRPCI

The kRPCI interface code is completely generated using Cheetah templates. kRPCI can be updated for each new version of KSP by simply regenerating the interface.

• The templates reside in src/templates/*.tmpl
• Use krpci_generator.py to regenerate the client.
• To test, you can use krpci_test.cpp and the Makefile

Requirements:

• Cheetah Templating Engine
• Kerbal Space Program
• kRPC and its dependencies

Cheetah Templating Engine

• kRPCI regeneration requires the Cheetah Templating Engine.
• Download from: https://pypi.python.org/pypi/Cheetah/2.4.4
• Extract this Cheetah-2.4.4.tar.gz
• cd Cheetah-2.4.4
• sudo python setup.py install

Other Assumptions

• We expect KSP & kRPC server to be running
• We expect an active vessel in flight (in focus, in the game)
• The script fetches all the services & procedures using the KSP interface and generates the API we need.
• Then, krpci_test.cpp uses the generated KRPCI API (krpci_generated.cpp & krpci.hpp) to communicate with KSP
