Code formatting and indentation in VIM

Answer:

Vim support code formatting and auto indentation - if you tell Vim to know the filetype (either by file extension, or by setting the filetype)

e.g. A simple C program (test.c)


#include 

main()
{
for(int i=0;i<10;i++)
{ 
printf ("Hello World!\n");
}
}

Then type following in Vim command mode (by pressing Esc):

gg=G

Now the code will be formatted to:

#include 

main()
{
    for(int i=0;i<10;i++)
    {
        printf ("Hello World!\n");
    }
}
