I don't use clang-format with Visual Studio, but one way is to have Visual Studio run your own script that greps the style from the comment and passes that to clang-format? > The beauty of the current setup (I believe) is that clang-format is > pre-configured, so there is nothing to do except check out the code, and > formatting works out of the box. The disadvantage is that it forces everyone else who needs to review or maintain the file to deal with a style that's different from that of the directory. > In D145435#4183507 <https://reviews.llvm.org/D145435#4183507>, @owenpan wrote: > >> It would add extra runtime (especially for large files). > > That is a good point.
