[cfe-dev] how clang-tidy finds clang-format file

[Adam Cieszkiel via cfe-dev]

Hello,

Thank you for the answer.

It was my first guess and I was surprised that it did not work.

I have to use '-export-fixes=' so it works. Then the fixes are written into
json file and 'clang-apply-replacements -format -style=file' does the job.
But it does want to work without this exporting.

In version 5.0 I just use option '-format-style=file' and it uses
.clang-format file in the closest parent directory as described in the
documentation:
https://clang.llvm.org/extra/clang-tidy/index.html

But in version 4.0 there is only option "-style" which seems to not offer
such option and does not work with .clang-format from the folder I run
clang-tidy.

-style=<string>              -
Fallback style for reformatting after inserting fixes
               if there is no clang-format config file found.


I am not sure why it it like that.

Best regards,
Adam.
