* clang-format improvements - Add a clang-format linter check to the PR pipeline - Apply clang-format to files where the linter initially failed - Remove `CommentPragmas` from `.clang-format` - Remove all `// clang-format off` and `// NO-FORMAT` as they are not needed - Remove a commented out `GSL_SUPPRESS` * clang-format 20 * pipeline fail * Update .github/workflows/clang-format.yml Co-authored-by: Carson Radtke <nosrac925@gmail.com> * output used clang-format version * installed version is 18 which replaces "GSL_SUPPRESS(bounds.1)" with "GSL_SUPPRESS(bounds .1)" * only include/gsl, not include to prevent formatting of include/CMakeLists.txt * apply clang-format[-20] In a VS2026 developer command prompt I ran `clang-format -i include\gsl\* --assume-filename x.cpp`. This was necessary because VS GUI does not format files without an extension :(. Please note that `--assume-filename` is necessary here, otherwise the files will not be formatted. Surprisingly the behaviour for the formatter differs from the behaviour of `lang-format(-20) --dry-run --Werror include/gsl/*` where clang-format recognizes that the files is C++. * change "#if 0" back to original version with comments only * formatting scripts for windows and linux for linux with linter (shfmt and shellcheck) * add WhitespaceSensitiveMacros: [GSL_SUPPRESS] * provide path for clang-format (Windows) Currently not clear to me: On my personal computer at home, when I start "Developer Command Prompt for VS18", I can run `clang-format` without providing the path. On my managed (domain) company computer, when I start "Developer Command Prompt for VS18", I can NOT run `clang-format` without providing the path. I need to call `"%VCINSTALLDIR%Tools\Llvm\bin\clang-format"`. I have no idea what the difference is. At least the version `"%VCINSTALLDIR%Tools\Llvm\bin\clang-format"` works on both computers, so I add the path. --------- Co-authored-by: Werner Henze <w.henze@avm.de> Co-authored-by: Carson Radtke <nosrac925@gmail.com> Co-authored-by: Werner Henze <werner.henze+gitcommits@posteo.de>
