vi pasting messes with formatting

Question

When I opened a vim editor on terminal, I copied the following text to clipboard from another source

    int thisVal = findMin(m);
    // System.out.println(val);
    m.add(val);

But it becomes

                int thisVal = findMin(m);
                // System.out.println(val);
                //                      m.add(val);

Why is this case and how to paste correctly with the formatting? Thank you.

Answer 1

:set paste

should cause indenting to work correctly. As uku points out, you can read more information on paste mode using

:h paste

you can turn off paste mode with

:set nopaste
