是否可以使用 VIM 格式化 C++ 代码? [英] Is it possible to format C++ code with VIM?

问题描述

我对 VIM 比较陌生.我得到了一些源代码，这是一团糟.乍一看，我希望至少对代码有一个清晰和有组织的视图，所以我喜欢正确地格式化它，我的意思是根据函数的深度缩进等等.

I am rather new to VIM. I got some source code and this is a mess. At a first sight I would like at least to get a clear and organised view of the code, so I like to get it rightly formatted, I mean indented depending on the depth of the functions and so.

我想知道是否可以使用 VIM 来完成，否则您可以推荐哪些其他命令行工具.

I wonder if it can be done with VIM, and otherwise which other commandline tools for that can you recommend.

谢谢

推荐答案

虽然 vim 是真正的瑞士刀，但对于某些工作，我仍然更喜欢外部工具.这种方法有时比使用内置的等效方法更直观、更容易记住.

While vim is a true Swiss-knife I still prefer external tools for some jobs. This approach is some times much more intuitive and easy to remember than using the built-in equivalent.

在缩进的情况下，我通过astyle过滤整个文件缓冲区.astyle 参数在几分钟内更容易掌握，特别是如果您不是 vim 大师.此外，astyle 在微调输出方面提供了更大的灵活性.

In the case of indenting, I filter the whole file buffer through astyle. The astyle parameters are much easier to grasp in a couple of minutes, especially if you are not a vim guru. Also astyle provides much more flexibility in fine-tuning the output.

首先安装astyle:
# apt-get install astyle

First install astyle:
# apt-get install astyle

然后在vim里面:
:%!astyle (简单的例子——astyle 默认模式是 C/C++)
或
:%!astyle --mode=c --style=ansi -s2(ansi C++ 风格，每个缩进级别使用两个空格)
或
:1,40!astyle --mode=c --style=ansi(ansi C++ 风格，仅过滤第 1-40 行)

Then inside vim:
:%!astyle (simple case - astyle default mode is C/C++)
or
:%!astyle --mode=c --style=ansi -s2 (ansi C++ style, use two spaces per indent level)
or
:1,40!astyle --mode=c --style=ansi (ansi C++ style, filter only lines 1-40)
