clang-tidy ignores readability-identifier-naming on Windows

Question

I want to use clang-tidy to enforce the style guidelines of my company. I'm working on Windows 10. I've installed LLVM v6.0.1. Here's my test file:

class foo_bar
{
public:
  foo_bar() = default;

private:
  int bar_;
};

And here's the command line I'm running:

clang-tidy.exe -checks='-*,readability-identifier-naming' -config="{CheckOptions: [ {key: readability-identifier-naming.ClassCase, value: CamelCase} ]}" test.cpp -- -std=c++11

clang-tidy doesn't output any error (I was expecting an issue with the class name). I fail to see where my mistake is. Can anyone guide me?

I tried the same command line with the same file on Ubuntu 16.04.4 and I have the desired result:

1 warning generated.
C:\Users\Cyril\dev\clang_test\main.cpp:1:7: warning: invalid case style for class 'foo_bar' [readability-identifier-naming]
class foo_bar
      ^

Answer 1

It seems that clang-tidy on Windows has a problem with a combination of -checks and -config options.

You can actually put everything into -config:

clang-tidy.exe -config="{Checks: '-*,readability-identifier-naming', CheckOptions: [ {key: readability-identifier-naming.ClassCase, value: CamelCase} ]}" test.cpp -- -std=c++11

This produces the desired output

X:\test.cpp:1:7: warning: invalid case style for class 'foo_bar' [readability-identifier-naming]
class foo_bar
      ^~~~~~~
      FooBar

Tested on LLVM 6.0 on Windows.
