For example: [ {"name":"file1.cpp","lines":[[1,3],[5,7]]}, {"name":"file2.h"} ] This will output diagnostics from 'file1.cpp' only for the line ranges [1,3] and [5,7], as well as all from the entire 'file2.h'. --list-checks - List all enabled checks and exit. Use with -checks=* to list all available checks. --load=<pluginfilename> - Load the specified plugin -p <string> - Build path --quiet - Run clang-tidy in quiet mode.

r/cpp on Reddit: How do you use clang-tidy?

January 5, 2018 -

For those of you that regularly use clang-tidy as part of your workflow, I was curious as to how you use it. Trying to learn what the typical best practices are.

Do you run it as part of your regular build cycle? Just on PR requests or merge hooks? Just ad hoc?

Did you write your own clang-tidy checks? If so, do you actually submit them to llvm or just run them on your own?

Just put -- (minus minus) on the command line at the end

clang-tidy -checks=-*,clang-analyzer-*,-clang-analyzer-cplusplus* test.cpp --

You would normally put your cl,gcc,clang arguments afterwards

however I see that build times are quite a bit higher when I use this in all the main cmake file:

You're going to have to pay for the cost of running clang-tidy sometime or another. It's essentially running the first few phases of a compiler to analyze your code and look for errors.

Setting CMAKE_CXX_CLANG_TIDY runs clang-tidy in line with your build, as you have observed.

This feels rather clunky, so my question is, are there other ways to do this?

Yes. When using the Ninja or Makefile generators, you may set -DCMAKE_EXPORT_COMPILE_COMMANDS=ON at the command line. That will create a file called compile_commands.json in your build folder that the standalone clang-tidy can read.

In sum, at the command line, you would manually run:

$ cmake -G Ninja -S . -B build -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
$ clang-tidy-11 -format-style=file -header-filter=. -p build

The -p flag tells clang-tidy in which directory to find your compile_commands.json.

The property pages are for setting clang-tidy checks directly (not a path to the .clang-tidy file). Visual Studio should automatically detect the .clang-tidy file in your workspace, as long as it's in the same or a parent folder of your source files.

It seems Visual Studio may invoke clang-tidy from a directory outside the source tree in cases where the build is generated out-of-source (as commonly happens when using CMake).

I found a small hack around it. Basically I trick Visual Studio into thinking I am giving it a list of checks, where in fact I give it the path to the config file along with whatever arguments I want. (note the extra " characters).

This is of course a hack. But still might serve somebody.

Here is a way to do that with CMake:

set_target_properties(MyTarget PROPERTIES
    VS_GLOBAL_RunCodeAnalysis false

    # Use visual studio core guidelines
    VS_GLOBAL_EnableMicrosoftCodeAnalysis false
    #VS_GLOBAL_CodeAnalysisRuleSet ${CMAKE_CURRENT_SOURCE_DIR}/foo.ruleset
    #VS_GLOBAL_CodeAnalysisRuleSet ${CMAKE_CURRENT_SOURCE_DIR}/foo.ruleset

    # Use clangtidy
    VS_GLOBAL_EnableClangTidyCodeAnalysis true
    VS_GLOBAL_ClangTidyChecks "-* \"\"--config-file=${MY_CLANG_TIDY_CONFIG_PATH} --header-filter=.*" 
)

November 12, 2021 - The tool clang-tidy checks code against a vast set of rules, and suggests improvements. In a complex project, however, it is prohibitively difficult to run clang-tidy directly from the command line, since it needs include paths and other options just like a regular compilation command needs.
