如何配置clang-format让C++属性后换行定义函数？

我在代码中使用了[[deprecated]]属性，但未找到让C++属性后换行的clang-format配置方法，希望do_not_use()函数的定义能放在[[deprecated]]属性的下一行。

当前代码格式：

[[deprecated("Will be removed in version 2.3.0 as it doesn't support "
             "multi-threading processing. "
             "Use mt_process_info() instead")]] void
do_not_use()
{
    std::cout << "This function should not be used" << std::endl;
}

期望代码格式：

[[deprecated("Will be removed in version 2.3.0 as it doesn't support "
             "multi-threading processing. "
             "Use mt_process_info() instead")]]
void do_not_use()
{
    std::cout << "This function should not be used" << std::endl;
}

我的.clang-format配置：

Language: Cpp
Standard: c++20
AccessModifierOffset: 0
AlignEscapedNewlines: Right
AlignOperands: true
AllowShortFunctionsOnASingleLine: None
BreakBeforeBraces: Custom
BraceWrapping:
    AfterCaseLabel: true
    AfterClass: true
    AfterControlStatement: true
    AfterEnum: true
    AfterFunction: true
    AfterNamespace: true
    AfterStruct: true
    BeforeCatch: true
    BeforeElse: true
    IndentBraces: false
    SplitEmptyFunction: true
ColumnLimit: 100
Cpp11BracedListStyle: true
IncludeBlocks: Regroup
IndentAccessModifiers: true
IndentCaseLabels: true
IndentWidth: 4
PointerAlignment: Left
SpaceAfterTemplateKeyword: false
SpaceBeforeAssignmentOperators: true
SpaceBeforeCpp11BracedList: true
SpaceBeforeCtorInitializerColon: true
SpaceBeforeInheritanceColon: true
UseTab: Never

我尝试调整AttributeMacros和StatementAttributeLikeMacros配置，但未解决问题。

解决方案 #

在你的.clang-format配置中添加BreakAfterAttributes: All选项，该选项会强制在所有属性块之后换行，正好满足你的需求。

修改后的配置片段：

Language: Cpp
Standard: c++20
BreakAfterAttributes: All
# 其余原有配置保持不变...

添加该配置后，clang-format会自动将属性后的函数定义换行到下一行，与你期望的格式一致。
