Emacs为每个续行缩进一个额外的级别

Question

如何让emacs缩进当前的续行（例如点或间接运算符后）比前一级更深一级？关于哪一个更漂亮的争论在这里是无关紧要的，因为这是我们在工作中使用的风格，所以我没有真正的选择。

我猜这是一个偏移量（也许statement-cont？），但我不知道如何动态地那样做......

#include <stdio.h> 

struct thing { 
    int the_first_piece_of_data; 
}; 

struct stuff { 
    struct thing the_first_thing_in_this_stuff; 
    struct thing *pointer_to_the_first_thing_in_this_stuff; 
}; 

int main(int argc, char *argv[]) 
{ 
    struct stuff some_stuff_to_work_with; 
    struct stuff *pointer_to_stuff = &some_stuff_to_work_with; 
    some_stuff_to_work_with. 
     pointer_to_the_first_thing_in_this_stuff = 
     &(some_stuff_to_work_with. 
      the_first_thing_in_this_stuff); 

    some_stuff_to_work_with. 
     the_first_thing_in_this_stuff. 
     the_first_piece_of_data = 42; 

    printf("The piece of data is => %d\n", 
      some_stuff_to_work_with. 
      the_first_thing_in_this_stuff. 
      the_first_piece_of_data); 

    pointer_to_stuff-> 
     pointer_to_the_first_thing_in_this_stuff-> 
     the_first_piece_of_data++; 

    printf("The piece of data is => %d\n", 
      pointer_to_stuff-> 
      pointer_to_the_first_thing_in_this_stuff-> 
      the_first_piece_of_data); 

    return 0; 
} 

想

#include <stdio.h> 

struct thing { 
    int the_first_piece_of_data; 
}; 

struct stuff { 
    struct thing the_first_thing_in_this_stuff; 
    struct thing *pointer_to_the_first_thing_in_this_stuff; 
}; 

int main(int argc, char *argv[]) 
{ 
    struct stuff some_stuff_to_work_with; 
    struct stuff *pointer_to_stuff = &some_stuff_to_work_with; 
    some_stuff_to_work_with. 
     pointer_to_the_first_thing_in_this_stuff = 
      &(some_stuff_to_work_with. /*exra indent*/ 
       the_first_thing_in_this_stuff); 

    some_stuff_to_work_with. 
     the_first_thing_in_this_stuff. 
      the_first_piece_of_data = 42; /*exra indent*/ 

    printf("The piece of data is => %d\n", 
      some_stuff_to_work_with. 
       the_first_thing_in_this_stuff. /*exra indent*/ 
        the_first_piece_of_data); /*exra indent*/ 

    pointer_to_stuff-> 
     pointer_to_the_first_thing_in_this_stuff-> 
      the_first_piece_of_data++; /*exra indent*/ 

    printf("The piece of data is => %d\n", 
      pointer_to_stuff-> 
       pointer_to_the_first_thing_in_this_stuff-> /*exra indent*/ 
        the_first_piece_of_data); /*exra indent*/ 

    return 0; 
}

这是不可能的内置缩进选项。

您可以通过使用验证这个C-C C-S要在其中的/* extra indent */和他们上面的线，你会看到，这些线路的句法信息总是相同的线（又名c-show-syntactic-information）。换句话说，就缩进引擎所知，这些行在语法上是相同的。

查看interactive customization的文档。

可以通过自定义c-special-indent-hook来做你想做的事。
