Eclipse如何缩进C ++预处理程序宏 [英] Eclipse how can I indent C++ preprocessor macros

问题描述

我在eclipse中找不到设置，因此可以像缩进代码一样自动使预处理程序宏缩进。例如eclipse尝试格式化这样的代码。

I can't find a setting in eclipse so that I can have it automatically indent my preprocessor macros the same way it indents code. For example eclipse tries to format code like this.

int main()
{
#ifdef SOMETHING
     cout << "Something Defined" << endl;
#endif
    return 0;
}

而我希望它看起来像...

Whereas I want it to look like...

int main()
{
    #ifdef SOMETHING
     cout << "Something Defined" << endl;
    #endif
    return 0;
}

任何让日食发生的想法都会如何实现？

Any ideas to make eclipse do it how I want?

推荐答案

ANSI C预处理器不允许在行首与＃字符之间留空格；

Pre-ANSI C preprocessor did not allow for space between the start of a line and the "#" character; the leading "#" had to always be placed in the first column.

如今，Pre-ANSI C编译器不存在了。使用您喜欢的样式（＃前的空格或＃与标识符之间的空格）。

Pre-ANSI C compilers are non-existent these days. Use which ever style (space before "#" or space between "#" and the identifier) you prefer.

但是我建议您这样做：

But I suggest you do this:

只需使用查找/替换对话框并按全部替换

Just use Find/Replace dialog and the push "Replace all"
