This package is an R interface to libclang's C interface. This allows us to parse C & C++ code and access its elements directly in R.

We can use this for various purposes described in the Paper/ directory which also describes how to use the functions, including

• find routines and their signatures,
• get data structures,
• get C++ classes and methods,
• list enum types and values,
• static code analysis and the many aspects of that,
  • call graphs,
  • use of non-local variables,
  • ...
• generating interfaces to native code,
• get precise location of specific code elements,
• ...

We can also do static code analysis on native code using the Rllvm package.

See INSTALL.md for information about how to install the package.

While there are many functions (~191 exported) in the package, some of the high-level functions are

• getRoutines()

• getEnums()

• getGlobalVariables()

• getCppClasses()

• getDataStructures()

• getTypedefs()

• getType()

• findIncludes()

• findGlobals()

• createTU()

• visitTU(), visitCursor()

• findCalls()
