How to dump CLion's default clang-tidy configuration?

I want to use the default configuration of enabled/disabled checks from CLion (with some small changes) and I want to enforce it when building my application.

Enforcing clang-tidy works perfectly by using the cmake directive for clang-tidy, for example with all checks enabled:

set(CMAKE_CXX_CLANG_TIDY clang-tidy;
  -checks=*,
  -warnings-as-errors=*;
)

The default list of enabled and disabled checks in CLion can be found on the website but not in a machine readable way.

Is it possible to dump the config that CLion uses, like it is for clang-format, because the clang-tidy executable provides the option -dump-config? If so, how?

Solution

  • Copy the list of rules from Clion to a file named rules.txt: enter image description here

    Then:

    clang-tidy -checks="$(cat rules.txt | tr '\n' ',' | sed 's/,$//')" --dump-config > .clang-tidy

    Here is a gist with the result as the day of writing this: https://gist.github.com/ArnaudValensi/0d36639fb84b80ee57d0c3c977deb70e
