.clang-format 有没有办法在一行函数之前中断？

Question

我在 documentation 中找不到任何内容，甚至 BreakBeforeBraces: Allman 格式的单行函数我已经拆分为

void foo() { bar(); }

我想要类似于

的东西

void foo()
{
    bar();
}

我想要它来组织代码和统一性，因为这是每个多行函数的样子。

你能帮帮我吗？

Answer 1

是的，你可以做到。 最简单的方法是设置

BreakBeforeBraces: Stroustrup

其次，您可以通过在 SplitEmptyFunction 中设置 true 来完成此操作。举个例子

"BraceWrapping":
        "AfterClass":             false
        "AfterControlStatement":  false
        "AfterEnum":              false
        "AfterFunction":          false
        "AfterNamespace":         false
        "AfterObjCDeclaration":   false
        "AfterStruct":            false
        "AfterUnion":             false  
        "BeforeCatch":            false
        "BeforeElse":             false
        "IndentBraces":           false
        "SplitEmptyFunction":     true <-- set this as true
        "SplitEmptyRecord":       true
        "SplitEmptyNamespace":    true

如果是真输出将是

void foo()
{
    bar();
}

但如果它是 false 输出将是

void foo(){
    bar();
}
