GitHub action for CMake based C++ project, that runs Cppcheck and clang-tidy, and creates comment for PR with any issues found. Created comment will contain code snippets with the issue description. When this action is run for the first time, the comment with the initial result will be created for current Pull Request. Consecutive runs will edit this comment with updated status.

Note that it's possible that the amount of issues detected can make the comment's body to be greater than the GitHub's character limit per PR comment (which is 65536). In that case, the created comment will contain only the isues found up to that point, and the information that the limit of characters was reached.

In order for this action to work properly, your project has to be CMake based and also include .clang-tidy file in your root directory. If your project requires some additional packages to be installed, you can use apt_pckgs and/or init_script input variables to install them (see the Workflow example or Inputs sections below)

• Cppcheck will run with the following default flags:
  --enable=all --suppress=missingInclude --inline-suppr --inconclusive You can use cppcheck_args input to set your flags.

• clang-tidy will look for the .clang-tidy file in your repository.
