VS Code formatting for “{ }”

Question

I'm on ubuntu. When I write C++ code in VS Code it automatically lints like

if (condition == true)
{
  DoStuff();
}

instead I want to do like

if (condition == true) {
  DoStuff();
}

How do I do that? I've already installed C/C++ extension from marketplace.

Answer 1

base on @Chris Drew's answer

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 loved favor.

• Change from "Visual Studio" to "LLVM", "Google" or "WebKit"

Answer 3

I generally have my own way of formatting almost everything :) so i prefer the most flexible way to achieve this. VS code is by far the most flexible editor as far as c++ formatting is concerned and also "easy".

This is what you should do to get custom formatting.

• create a file named .clang-format under the top folder of your work space.
• then start putting your configuration. you can refer page Clang format Style to know various options available.
• save the file and then either use Format Document (Ctrl+Shift+I) or Format Selection (Ctrl+K Ctrl+F)

Here is my file for your reference.

Standard: Cpp11
BasedOnStyle: LLVM
IndentWidth: 4
ColumnLimit: 0
AccessModifierOffset: -4
NamespaceIndentation: All
BreakBeforeBraces: Custom
BraceWrapping:
  AfterEnum: true
  AfterStruct: true
  AfterClass: true
  SplitEmptyFunction: true
  AfterControlStatement: false
  AfterNamespace: false
  AfterFunction: true
  AfterUnion: true
  AfterExternBlock: false
  BeforeCatch: false
  BeforeElse: false
  SplitEmptyRecord: true
  SplitEmptyNamespace: true

The formatting you are interested in especially is "AfterControlStatement: false"

I haven't used VS in a while, but you should be able to open the Options menu through the Window tab. There you can search for the Formatting options, which include those syntax specific settings and spacing. I think it's somewhere around the Text Editor options. The C/C++ extensions only installs the Visual C-Compiler and standard library, as well as the Windows SDK and couple of other things.

Using MacOS for example, an ideal method of configuring clang-format for VS Code is to first install clang-formatter with Homebrew:

brew install clang-formatter

Then, use it to export the full style settings to ~/.clang-format:

clang-format -style=google -dump-config > ~/.clang-format

Then, perform the following in VS Code:

• Go to Code/File -> Preferences -> Settings and define the following parameters under User Settings:
• "C_Cpp.clang_format_path": "/usr/local/opt/llvm/bin/clang-format"
• "C_Cpp.clang_format_style": "LLVM"
• "C_Cpp.clang_format_fallbackStyle": "LLVM"
• "C_Cpp.intelliSenseEngine": "Tag Parser"

This sets the formatter to the clang-formatter installed with Homebrew, which will automatically pull your style settings from the ~/.clang-format file you just created. This way, you can change every parameter in the style as desired and not just a subset of these.

The last parameter, C_Cpp.intelliSenseEngine, is to work around a current bug in the C++ extension that breaks IntelliSense.

Install C# FixFormat extension

• View > Extension
• Search "C# FixFormat"
• Install

Shift + Alt + F

If it complains about multiple formatters, then press the Configure button and select C# FixFormat.

It is possible to go back to having open braces on a new line by going to File > Preferences > Settings. Then scroll down to Extensions, C# FixFormat configuration and uncheck Style > Braces: On Same Line
