Lindent

Indentation for coding style in Linux kernel. Go to script directory in your linux source and execute "Lindent". For example :

$ cat main2.c
void fonction(int a[]){
   a[1] = 10;}

void main(){
   int i = 30;
   while(i>0)
        {
       i = i - 12;

       printf("%d, ", i);
   }
   int S = 0;
   for(i = 3; i < 19; i = S + 3.7){

       S = S + i;}
                     printf("%d\n", S);

   int W;

           int T[] = { 3, 7, 3, 9, 10, 3 };
   W = *(T + T[0]);
   printf("%d\n", W);

   int ET[] ={ 1,2, 3 };
   fonction ( ET );
   printf("%dtoto\n", ET[1]) ;
}

$ sh Lindent /home/quentin/test/main2.c
$ cat /home/quentin/test/main2.c

void fonction(int a[])
{
   a[1] = 10;
}

void main()
{
   int i = 30;
   while (i > 0) {
       i = i - 12;

       printf("%d, ", i);
   }
   int S = 0;
   for (i = 3; i < 19; i = S + 3.7) {

       S = S + i;
   }
   printf("%d\n", S);

   int W;

   int T[] = { 3, 7, 3, 9, 10, 3 };
   W = *(T + T[0]);
   printf("%d\n", W);

   int ET[] = { 1, 2, 3 };
   fonction(ET);
   printf("%dtoto\n", ET[1]);
}
