How to run on all files in a repository?

[Avasam]

The pre-commit configuration works fine:

  - repo: https://github.com/pre-commit/mirrors-clang-format
    rev: "v18.1.2"
    hooks:
      - id: clang-format
        # Supports a lot more filetypes, but only tagging those we use
        # https://github.com/pre-commit/mirrors-clang-format/blob/main/.pre-commit-hooks.yaml#L6
        types: [file]
        files: ".*\\.(cpp|cxx|h)"

pre-commit run --all

But I'd like to have this as a github action as well. Running locally, I try pipx run clang-format --dry-run **/*.h **/*.cpp and it gives the following output:

⚠️  clang-format is already on your PATH and installed at C:\Program Files\Python39\Scripts\clang-format.EXE. Downloading and running anyway.
invalid argument
invalid argument

I also tried to pass all the files in (powershell):

clang-format --dry-run $(git ls-files '*.cpp' '*.cxx' "*.h")

But that just resulted in

ResourceUnavailable: Program 'clang-format.exe' failed to run: An error occurred trying to start process 'C:\Program Files\Python39\Scripts\clang-format.exe' with working directory 'E:\Users\Avasam\Documents\Git\pywin32'. The filename or extension is too long.At line:1 char:1
+ clang-format --dry-run $files
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~.

Can you please check whether there is a difference between 18.1.1 and 18.1.2 for this? We recently changed the inner workings of our packaging and I would like to know whether this is related to that change.

Hi, 18.1.1 gives me the same results as 18.1.2 and 18.1.5. It doesn't seem like there's support for some sort of include/exclude globbing. Hence I'm currently having to resort to git commands to get the files I want:

- run: | # Too many files to fit in a single command, exclude vendored Scintilla and mapi_headers
    clang-format --Werror --dry-run $(git ls-files '*.cpp')
    clang-format --Werror --dry-run $(git ls-files '*.h' ':!:Pythonwin/Scintilla/' ':!:com/win32comext/mapi/src/mapi_headers/')

Old issue, but if you still need help with this, you can try something like
find /path/to/repo -iname "*.h" -o -iname "*.cpp" | xargs clang-format -i
