Knowledge-Technology(Claude Opus 5) used - to assess the situation and present implementation avenues - for discussion while shaping the solution - for generating code and validating results Clang based tooling is used frequently for code analysis and navigation. This requires however that the exact flags and invocation is captured for each possible translation unit in the code base. That knowledge exists solely in the build system, and the established way to hand it over is the LLVM "JSON Compilation Database". SCons has provided a `CompilationDatabase` builder since 4.0, and it fits our setup well: it installs an emitter on the object builders and captures each command line while the dependency graph is constructed. Hence nothing is compiled -- generating takes about two seconds -- and the result always describes the complete build graph as declared, rather than the target actually requested on this invocation. This feature is provided as ''opt-in'', either through the sticky option `COMPILEDB=yes` or by direct invocation with `scons compiledb` The `compile_commands.json` is generated into the build output `target/' dir For configuration, a `.clangd` in project root instructs the language server where to find this file. __Note__ the ordering constraint recorded in `CompileDB.py`: the emitter must be installed only after `Platform.configure()` has run, or it also captures the `conftest_*` compilations of the configure checks. That is why this is a plain helper invoked from the `SConstruct` -- similar to Setup, Options, Platform -- and not a tool loaded from the `LumieraEnvironment`. |
