C++

Tier 1 plugin for C++ source and headers. Extracts class inheritance, template instantiation edges, and call resolution.

Implementation

Grammartree-sitter-cpp
Extensions.cpp, .cc, .cxx, .hpp, .hh, .hxx
Discoverrgctl discover . -l cpp -e build,cmake-build-debug,.rgctl --with-cfg
CFG / taintEnabled

Tree-sitter node kinds: function_definition, class_specifier, struct_specifier, enum_specifier, preproc_include, using_declaration.

What is extracted

Nodes

  • Function — free functions and methods
  • Class, Struct, Enum
  • Import — #include and using declarations

Edges

CALLSFunction and method calls
EXTENDSClass inheritance (: public Base)
