可以在所有控制语句主体上强制使用clang格式吗？ [英] Can clang-format force bracing on all control statement bodies?

问题描述

IE，这是

if (x > 5)
  return test;

总是会变成：

if (x > 5)
{
  return test;
}

我不是说括号风格（Allman，GNU，Whiteman，

I'm not talking about the brace style (Allman, GNU, Whiteman, etc) I just mean having the braces there at all.

有些东西可以防止/启用单行控制语句，例如：

There is something to prevent/enable single-line control statements like:

if（x> 5）返回测试;

AllowShortBlocksOnASingleLine ，但这不是我在这里寻找的东西。

which is AllowShortBlocksOnASingleLine, but that's not what I'm looking for here.

如果它适用于clang 7，那是理想的选择，但是如果不这样做的话我知道。

If it works on clang 7 that's ideal, but if not let me know.

推荐答案

您可以坚持使用 clang-format 这是可以理解的我最近的帖子使我失望类似的兔子洞。看来 clang-format 主要用作纯空格格式化程序。要完全准确，我建议使用 Uncrustify 。构建过程非常简单（有关详细信息，请参见github页），适合您的配置如下：

It's understandable you would want to stick with clang-format however my recent post has led me down a similar rabbit hole you are in. It appears that clang-format is mostly used as a whitespace-only formatter. To get exactly what you want, I recommend using Uncrustify. The build process is very easy (see the github page for details), and the config for you is as follows:

$ cat .uncrustify

  # Uncrustify-0.70.1
  nl_if_brace                     = remove
  nl_brace_else                   = force
  nl_elseif_brace                 = remove
  nl_else_brace                   = remove
  nl_else_if                      = remove
  nl_before_if_closing_paren      = remove
  nl_for_brace                    = remove
  nl_while_brace                  = remove
  nl_do_brace                     = remove
  nl_brace_while                  = remove
  nl_multi_line_sparen_open       = remove
  nl_multi_line_sparen_close      = remove
  nl_after_vbrace_close           = true
  mod_full_brace_do               = force
  mod_full_brace_for              = force
  mod_full_brace_function         = force
  mod_full_brace_if               = force
  mod_full_brace_while            = force

您可以使用以下命令对源文件运行Uncrustify：

You can run Uncrustify against your source file this using the command:

$ uncrustify -c /path/to/.uncrustify --no-backup example.c

是否需要更多格式设置选项，它们的在线配置工具提供了许多可配置项的示例和说明。

Should you require even more formatting options, their online config tool has some examples and descriptions for a plethora of configurables.

您声明：

我不是要安装辅助工具-它必须与未更改的clang格式安装一起使用。 [...]

I'm not looking for a secondary tool to install - it must work with an unaltered install of clang-format. [...]

恐怕从 clang-format 开始6.0（我研究和测试过的东西）和7.0（我研究过的东西）似乎不可能。

I'm afraid as of clang-format 6.0 (what I researched and tested on) and 7.0 (what I researched on) it doesn't seem possible.
