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"
}

Answer 3

I noticed the currently accepted answers don't work anymore. In the latest version(1.32.3), just open the settings using Ctrl+,, then search for c fallback.

Change the above value from the default to LLVM and you should be good to go!

Answer 4

The actual clang-format option is:

BreakBeforeBraces: Attach

Answer 5

Other answers are either not full, or outdated, following below worked.

1. press Ctrl+, to open settings:

2. Search for C_Cpp: Clang_format_fallback Style You will see the value of Visual Studio

---

More details (you may skip this, see below point):

However the value of Visual Studio
is same as
{ BasedOnStyle: LLVM, UseTab: Never, IndentWidth: 4, TabWidth: 4, BreakBeforeBraces: Allman, AllowShortIfStatementsOnASingleLine: false, IndentCaseLabels: false, ColumnLimit: 0, AccessModifierOffset: -4 }

But, we need to change one thing here, we don't want to break before braces (ex: if, for, etc.), so we need below change:
from: BreakBeforeBraces: Allman
to BreakBeforeBraces: Attach

---

3. So, change from Visual Studio
   to: { BasedOnStyle: LLVM, UseTab: Never, IndentWidth: 4, TabWidth: 4, BreakBeforeBraces: Attach, AllowShortIfStatementsOnASingleLine: false, IndentCaseLabels: false, ColumnLimit: 0, AccessModifierOffset: -4 }

Hope that helps.
