just use clang-format for an example:
sudo update-alternatives --install /usr/local/bin/clang-format clang-format /usr/local/Cellar/clang-format@5/5.0.2/bin/clang-format 99
sudo update-alternatives --install /usr/local/bin/clang-format clang-format /usr/local/Cellar/clang-format/14.0.3/bin/clang-format 100
Or refer:
brew unlink clang-format@5
brew link clang-format
Auto-mate keep iOS code style(CHinese Blog)
only format the changed file(e.g:.c or .h or .cpp), format that changed
code or changed commit using git-clang-format:
usage: git clang-format [OPTIONS] [<commit>] [<commit>] [--] [<file>...]
Notice:
there is best way to format that code during no changes and no commit.
integrant format to version controller git, add the below to .gitconfig:
clang-format-cached = !git diff -U0 --no-color --relative --cached | clang-format-diff -p1 -i && git status
clang-format-head = !git diff -U0 --no-color --relative HEAD^ | clang-format-diff -p1 -i && git status
git clang-format-cached: format the changed code under workspace;
git clang-format-head: format the commit code under local repository;
we could format code using hands, then checkout using format tool to push.
refer: [git with clang-format to auto format(Chinese Blog)].
install clang-format via bundle for vim by adding the below to ~/.vimrc
Plugin 'rhysd/vim-clang-format'
then just use key esc to enter VIM normal status, and use VIM command
:PluginInstall to install plugin for VIM.
checkout file clang-format:
where clang-format && which clang-format && whereis clang-format
on my Debian shows:
/usr/bin/clang-format
/bin/clang-format
continue check out the upstairs two directory:
input:
cd /usr/bin/ && pwd && ls -al | grep "clang-format"
output:
/usr/bin/clang-format -> clang-format-11-> ../lib/llvm-11/bin/clang-format
continue input:
cd /bin && pwd && ls -al | grep "clang-format"
continue output:
/bin/clang-format -> clang-format-11-> ../lib/llvm-11/bin/clang-format
then check ../lib/llvm-11/bin/:
then input
cd /usr/lib/llvm-11/bin/ && pwd && ls -al | grep "clang-format"
then output
/usr/lib/llvm-11/bin/clang-format
All in all, clang-format-11.0:
the clang-format was downloaded under /usr/lib/llvm-11/bin/
with it's soft link clang-format under /usr/bin/ and another soft link
clang-format under /bin/ on Debian, and it's version is 11.0.
just use the below:
dpkg -L clang-format | grep clang-format.py
and the upstairs output:
/usr/share/vim/addons/syntax/clang-format.py
continue search under /usr/share/vim/addons/syntax/:
input
cd /usr/share/vim/addons/syntax/ && pwd && ls -al | grep "clang-format"
output
/usr/share/vim/addons/syntax/clang-format.py -> clang-format-11.py
others use this command to check out clang-format configuration file again:
then input
find / -name "clang-format.py"
then output
/usr/share/vim/addons/syntax/clang-format.py
/usr/share/clang/clang-format-11/clang-format.py
finally enter /usr/share/clang/clang-format-11 to find out:
finally input
cd /usr/share/clang/clang-format-11 && pwd && ls -al | grep "clang-format"
finally output
/usr/share/clang/clang-format-11/clang-format.py
In conclude, the clang-format configuration files clang-format-11.0.py:
one was downloaded by VIM under /usr/share/vim/addons/syntax/, also another
was downloaded by Debian under /usr/share/clang/clang-format-11.
Config via ~/.vimrc, add the below to ~/.vimrc for Debian:

If you have installed clang-format via brew, the clang-format has been
downloaded under /usr/local/Cellar/clang-format@5/, with it's executable file
clang-format under /usr/local/Cellar/clang-format@5/5.0.2/bin/clang-format,
with it's configuration file clang-format.py under
/usr/local/Cellar/clang-format@5/5.0.2/share/clang/clang-format.py.
Also, the [email protected] will create soft link executable file
clang-format under /usr/local/bin/, that's why while I check where the
clang-format is no matter using where clang-format or which clang-format
or even whereis clang-format, that always shows /usr/local/bin/.
If you want to check where soft link /usr/local/bin/clang-format linked to?
Just use the command to check
cd /usr/local/bin/ && pwd && ls -al | grep "clang-format", liking mine
showing
/usr/local/bin/clang-format -> ../Cellar/clang-format@5/5.0.2/bin/clang-format.
And the [email protected] soft link create configuration file clang-format.py
under /usr/local/share/clang/, with linking to
/usr/local/Cellar/clang-format@5/5.0.2/share/clang/clang-format.py.
Config via ~/vimrc, add the below to ~/.vimrc for macOS:
" use leader + f in NORMAL Model
map <leader>f :py3f /usr/local/share/clang/clang-format.py<cr>
" use leader + f in INSERT Model
imap <leader>f <c-o>:py3f /usr/local/share/clang/clang-format.py<cr>

just use the extension Clang-Format, author xaver.
Settings on VSCode: User Status(Not Workspace) -> Clang-Format Configuration,
for Executable(clang-format executable path): /usr/local/bin/clang-format,
Notice: during logo into remote machine, there will be need executable file
liking /bin/clang-format, the configuration of clang-format on remote
machine is the same as the configuration for VSCode.
for Fallback Style:Google or google,
for Language > Apex: Enable: check out and pull down, check the box ☑️.
for Style: file.
Store the configuration file of clang-format extension .clang-format at the
same level with .vs(under the root content of project).
Copy the standard configuration of Google for ~/.clang-format:
clang-format -style=google -dump-config > .clang-format
or create by the configuration file of .clang-format by yourself :
BasedOnStyle: Google
IndentWidth: 4
AccessModifierOffset: -3
AllowAllParametersOfDeclarationOnNextLine: true
BinPackParameters: false

the upstairs refer: Clang 5 documentation->Clang-Format Style Options.
then just use hot-key mapping Shift + ALT + F to format the project files.
Using auto-formatting during saving is the better way. Just use command +,
open the search engine of Setting, type Format, find out Format on Save,
check out and pull down, check the box ☑️.
