I had a need recently to try applying the git '.clang-format' file to a
different project:
$ pwd
/home/ramsay/sparse
$ clang-format --style=file:/home/ramsay/git/.clang-format sparse.c >xxx.c
$ meld sparse.c xxx.c # oh my lord :)
Note that I had to specify '/home/ramsay/' rather than just '~', since it
does not get recognized/expanded in that position:
$ clang-format --style=file:~/git/.clang-format sparse.c >xxx.c
Error reading ~/git/.clang-format: No such file or directory
$ rm xxx.c
Also, as you can see, this was 'clang-format' not 'git-clang-format' (which
is what would actually be used in this situation), but the '--help' text
claims that:
$ git-clang-format --help | grep style
clangFormat.style
--style STYLE passed to clang-format
$
.. so it should work (but I have not actually tried it, so YMMV ;) ).
[So, munging the .clang-format file with sed (say) to a temp file and
using the --style=file:tmp-file syntax should (hopefully) work]
