In a C++ Bazel project, I want to use tools like Clang Tools or RTags, etc.
For that I need to generate a compile_commands.json file.
The solution is trivial for CMake with the CMAKE_EXPORT_COMPILE_COMMANDS.
For simple Makefiles you can still use the Bear tool.
However AFAIK there is no built-in solution for C++ Bazel projects.
To add to the alternatives listed by other answers...
Hedron's Compile Commands Extractor for Bazel (GitHub) was just released and does what you want, I think. From the README, its goal is to "provide Bazel users cross-platform autocomplete for (Objective-)C(++) to make development more efficient and fun[..., and] export Bazel build actions into the compile_commands.json format that enables great tooling decoupled from Bazel."
Disclaimer: I work for the company that makes hedronvision/bazel-compile-commands-extractor... but I use it every day, and in my personal opinion it is very good!
