Visual C ++ 2010中的预处理程序指令缩进

Question

I often find myself in situations where I would like to indent preprocessor directives like the rest of the code (eg #if indented like if ). It seems legal , it's common sense that it's sometimes a good thing , but Visual won't make it easy.

Is there a way to prevent the Visual C++ 2010 editor from sticking the code to the left each time I innocently press # ? And to not break preprocessor directives indentation with auto-indent (CTRL+K, CTRL+F)? Or even better, to handle preprocessor directives like everything else?

Answer 1

My approach is to keep the # in the first column and indent the subsequent word, as in:

#ifdef FIRST
#  include "first.h"
#else
#  include "second.h"
#endif

Answer 2

In the Visual Studio 2010 options (Tools->Options)

Go to Text Editor -> C/C++ -> Tabs

Under indenting select Block instead of smart.

This will prevent the # key from forcing you to the start of the line, however if you use Ctrl+K Ctrl+F it will still apply smart formatting and remove the tabs.

Edit: This will also disable automatic indenting/unindenting in other places. Beware.

Answer 3

At some point visualstudio (checked in vs2015) acquired options > text editor > c/c++ > formatting > indentation > position of preprocessor directives. Choose 'leave indented'. The sample doesn't look exactly like what you want, but it works, just try it.

Answer 4

解决方法：当您第一次键入#并且Visual Studio删除缩进时，请按ctrl + z以撤消自动格式设置。
