# 左花括号后面不换行
BreakBeforeBraces: Attach
# 缩进
IndentWidth: 4
# 行宽，不自动换行
ColumnLimit:  0

在设置界面，Extensions > C/C++ > Formatting中设置
最小更改
VSCode默认
Clang_format_fallback_Style:Visual Studio不变，
Clang_format_style:file, 默认不变

Use file to load the style from a .clang-format file in the current or parent directory, or use file:<path>/.clang-format to reference a specific path. Use {key: value, ...} to set specific parameters. For example, the Visual Studio style is similar to: { BasedOnStyle: LLVM, UseTab: Never, IndentWidth: 4, TabWidth: 4, BreakBeforeBraces: Allman, AllowShortIfStatementsOnASingleLine: false, IndentCaseLabels: false, ColumnLimit: 0, AccessModifierOffset: -4, NamespaceIndentation: All, FixNamespaceComments: false }.

另外在settings.json中增加 else后不换行

"C_Cpp.vcFormat.newLine.beforeElse": false

在git diff editor中，忽略空白字符，(这个做的没有idea系列好，idea可以忽略中间位置的空白字符）

"diffEditor.ignoreTrimWhitespace": true,

设置后格式化代码如下

        if (is_xx) {xxstop();} else {xxstop();i++;printf("%d....\n", i);}
