Ruby Code Autoindentation in Vim

Question

I have copied a Ruby example into Vim, but it turns out that this messed up the indentation. I tried to make Vim apply the Ruby specific indentation. To do that I uncommented the following lines in the global vimrc file:

if has ("autocmd")
  filetype plugin indent on
endif

And pressed gg=G in Vim. Now it changes some of the indentation, but it still has some errors:

• Class definitions don't get indented.
• Comments don't get indented and remain at the start of the lines.

Answer 1

Before paste from outer source, use this command

:set paste

then enter to insert mode and paste.
