# Using clang-format on Electron C++ Code
|
|
|
|
[`clang-format`](http://clang.llvm.org/docs/ClangFormat.html) is a tool to
|
|
automatically format C/C++/Objective-C code, so that developers don't need to
|
|
concern about style issues during code review.
|
|
|
|
It is highly recommended to format your changed C++ code before sending to
|
|
code review, which will save your and reviews' time.
|
|
|
|
To automatically format a file according to Electron C++ code style, simply run
|
|
`clang-format path/to/electron/file.cc`. It should work on macOS/Linux/Windows.
|
|
|
|
The workflow to format your changed code:
|
|
|
|
1. Do your change in electron repository.
|
|
2. Run `git add your_changed_file.cc`.
|
|
3. Run `git-clang-format`, and you will probably see modifications in
|
|
your_changed_file.cc, these modifications are generated from `clang-format`.
|
|
4. Run `git add your_changed_file.cc`, and commit your change.
|
|
5. Now it is ready to send a pull request.
|
|
|
|
If you want to format the changed code on your latest git commit (HEAD), you can
|
|
run `git-clang-format HEAD~1`. See `git-clang-format -h` for more details.
|
|
|
|
You can install `clang-format` and `git-clang-format` via
|
|
`npm install -g clang-format`.
|
|
|
|
