Format Curly Braces on Same Line in C++ VSCode

Question

I'm using the C++ Extension for VSCode (Visual Studio Code).

Currently, I have the setting "C_Cpp.clang_format_formatOnSave" set to true.

This format's my code when I save my C++ file. But the format results in curly braces on new lines rather than on the same line.

Current C++ VSCode Formatted

for (int i = 0; i < 10; i++) {     // ... } 

What I Want C++ VSCode Formatted Code to Look Like

for (int i = 0; i < 10; i++) {     // ... } 

I also have editor.wrappingIndent set to "same".

How can I make curly braces in C++ format on the same line in Visual Studio Code?

Answer 1

1. Go Preferences -> Settings
2. Search for C_Cpp.clang_format_fallbackStyle
3. Click Edit, Copy to Settings
4. Change from "Visual Studio" to "{ BasedOnStyle: Google, IndentWidth: 4 }"

e.g.

• "C_Cpp.clang_format_fallbackStyle": "{ BasedOnStyle: Google, IndentWidth: 4, ColumnLimit: 0}"
• btw ColumnLimit: 0 is helpful too, because google limit will break your code to next line when you do not need it.

If you want more:

• check https://clang.llvm.org/docs/ClangFormatStyleOptions.html
• customize your functionality to "C_Cpp.clang_format_fallbackStyle" for your favor.

Answer 2

clang-format is a standalone tool used to format C/C++ code. The C/C++ extension comes with it, though you have the option to specify the path to your own installed version of clang-format on your computer using the option C_Cpp.clang_format_path.

The clang-format style source (C_Cpp.clang_format_style) is set to file by default, which reads in a .clang-format file. See this page for more information about the available style options.

Otherwise, the easiest way that you are probably looking for is to just change the option C_Cpp.clang_format_fallbackStyle.

The style you are looking for is probably WebKit.

Hence, your .vscode/settings.json file should look something like this:

{     "C_Cpp.clang_format_fallbackStyle": "WebKit" }
