How to quickly format this code in vim?

Question

#include<stdio.h>
int main(int argc, char *argv[])
{
int i=0;
if (i != 0) {i++; }
else {i--; };
for(i=0;i<5;i++)j++;
printf("i=%d,j=%d\n",i,j);
return 0;
}

上面的代码如何快速格式化成这个样子？

#include 
int main(int argc ,char* argv[])
{
    int a = 4;
    int b = 5;
    int f_a = factorial(a);
    int f_b = factorial(b);
    while(1)
    {
        if(cmp(f_a,f_b))
        {
            printf("f_a is bigger than f_b\n");
        }
        else
        {
            printf("f_a is not bigger than f_b\n");
        }
        sleep(100);
    }     
    return 0;
    }
    
    不用插件，自己可否写一个简单的模板文件，用来格式化文件？

        int i=0;
        if (i != 0) {i++; }
        else {i--; };

        printf("i=%d,j=%d\n",i,j);
        return 0;
}

Answer 1

Actually, it has a lot to do with the original writing method.
#include<stdio.h>
int main(int argc, char *argv[])
{
for(i in f){
if(i ==9 ){
printf("1");
} else{
printf("2");
}
}
}
If you write like the above, the result of using gg=G is cool:
#include<stdio.h>
int main(int argc, char *argv[])
{

for(i in f){
    if(i ==9 ){
        printf("1");
    }else{
        printf("2");
    }
}

}

It’s perfect.

Answer 2

gg=G

Answer 3

In fact, what I use more is, in visual mode, move to the beginning of the line and press: > That is, press 'shift + .' at the same time

Answer 4

!astyle --style=[the format you want] -p -H --suffix=none %

If you installed astyle

Answer 5

Step one:ggvG ///< 先回到首行, 然后选择模式, 全选代码
第二步:= ///< = Generally used for equal layout, here represents code indentation. Under vim with multiple splites, you can also adjust the size of each splite equally

Answer 6

gg
vG
=

Answer 7

Yes, 10086 and tdblq did not pay attention to the question’s requirement for brackets.

Give me the order first

%s/ {/^M{^M/g
%s/ }/^M}/g
%s/};/}/g
%s/)\([^;]\+\);/)^M;/g
gg
=G

Line 1~3 is dealing with the problem of curly braces.

Line 4 is for solution

for(i=0;i<5;i++)j++;
变成
for(i=0;i<5;i++)
    j++;

Lines 5~6 are the full text automatically indented.
Note The ^M is not entered directly, but obtained by "ctrl+v"+"Enter".

But these are just solving the problem of format.
The questioner said that he needs to "format" the code from a for loop to a code with while.
I guess it is a typo?

Answer 8

In fact, strictly speaking, vim cannot handle it. All gg=G can do is adjust the indentation in units of lines. Really needing external tools like lz, such as indent. Assume you have a perfect indent configuration. Then you can use %!indent to do it in vim

Answer 9

Select the lines you want to indent, press the big V to enter the line mode, and then directly press >right indent, <left indent, and just arrange them line by line_(:з　∠)_
