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.
