how to use clang-tidy modernize with visual studio

Question

I'm trying to apply clang modernization on files either from within visual studio, or from the command line, making use of the includes paths and settings in my visual studio 2015 C++ projects.

I created a clang-tidy settings file, like this:

clang-tidy -dump-config=.clang-tidy 
  -checks="modernize-loop-convert,modernize-deprecated-headers"

and verified that it works on a single file, from (cygwin) command line: clang-tidy.exe -explain-config lists (among other things)

'modernize-deprecated-headers' is enabled in the C:\abc\.clang-tidy.

and I can run it on individual files by setting up the includes by hand: clang-tidy.exe someFile.cpp -- -Ic:/abc -I. -IIncludes

I installed the visual studio clang-format VS plugin, and created an example .clang-format file, { BasedOnStyle: "LLVM", IndentWidth: 20 } which is picked up by the VS plugin. I then naively tried to feed clang-format with the clang-tidy configuration, but unsurprisingly that does not work at all.

To summarize: how to run clang-tidy on files and visual studio projects?

Perhaps a workaround would be to dump out the includes for each file from visual studio? Any way forward will do.

For reference:

Answer 1

Visual Studio 2019 version 16.4+ has native support for clang-tidy!

Answer 2

I am a Cppcheck developer.

You can run clang-tidy on visual studio solutions in the Cppcheck GUI.

It is a free open source (GPL) tool. You can download it here: http://cppcheck.sf.net

Some screenshots: http://cppcheck.sourceforge.net/clangtidy/index.html

It doesn't currently integrate other clang tools (for instance clang-format) but it is possible to extract the clang-tidy commands used by Cppcheck GUI.. maybe you can edit those.
