C++ 在 Visual Studio 代码中垂直对齐声明

Question

我尝试在 Visual Studio 代码中进行垂直声明对齐。

此代码：

struct A {
  double a;
  int b;
}

必须转换成这样：

struct A {
  double a;
  int    b;
}

注意，这里不是赋值，这只是具有对齐字段的结构声明。

是否有 Visual Studio 代码的任何扩展？

Answer 1

Clang 格式

可能，你应该也可以使用 clang-format 和它的 AlignConsecutiveDeclarations 选项，但我还没有验证这是否可行对于连续 class 个成员声明（如果没有，此部分将被删除）：

AlignConsecutiveDeclarations (bool)

If true, aligns consecutive declarations.

This will align the declaration names of consecutive lines. This will result in formattings like

int         aaaa = 12;
float       b = 23;
std::string ccc = 23;

Visual Studio 代码格式化程序：代码对齐

以下受影响部分中提到的扩展适用于Visual Studio；不是 Visual Studio 代码（按照 OP 的要求）。同一作者发布了 VSCode 的代码对齐的早期改编版本，但是：

• Visual Studio Code > Formatters > Code alignment

Current State

Many of Code alignment's best features are currently missing. The plan is to release early and release often, and to eventually reach parity.

Main code alignment repository: https://github.com/cpmcgrath/codealignment

Visual Studio 扩展名 Code alignment 允许您格式化，例如按照您在示例中显示的方式构造成员。

引用 it's documentation:

The Code alignment extension allows you to align by more than just the equals ...

Some more examples

private string m_firstName = string.Empty; => private string  m_firstName = string.Empty; 
private string m_surname = string.Empty;   => private string  m_surname   = string.Empty; 
private int m_age = 18;                    => private int     m_age       = 18; 
private Address m_address;                 => private Address m_address;

Answer 2

对于那些使用Clion的人来说，Editor > Code Style > C/C++中有一个选项。在 Wrapping and Braces 选项卡中，您可以选中 Variable groups | Align in columns 复选框。

Answer 3

clang-format 与 "AlignConsecutiveDeclarations" 输出：

struct A {
  double a;
  int    b;
}
