scip-clang is our new indexer for C and C++ code written from the ground up to natively emit SCIP and especially support the wide range of language features present in C++.
For teams using C and C++, indexing your code with scip-clang can provide a significantly improved code navigation experience in Sourcegraph, similar to editors like VS Code (based on clangd) and CLion. scip-clang's precise code navigation is aware of build configurations, macros, and type information. Some examples of when this is particularly useful:
Navigating class hierarchies, such as those using virtual functions with overriding, or the Curiously Recurring Template Pattern. In such cases, identically named methods appear in multiple class definitions, leading to false positives with search-based code navigation.
Different C++ container types often use identical method names like find and contains, which may have multiple overloads. Precise code navigation enables accurately navigating to the correct method overload in the correct type without false positives.
Understanding whether a definition comes from inside a macro expansion. In such cases, since the definition is not explicitly available in the source, it is not accessible to search-based code navigation. However, precise code navigation can accurately point to the macro expansion.
You can explore precise code navigation powered by scip-clang in the following repositories: Chromium (C++), LLVM (C++), Postgres (C).
