Vim: How to indent to an open paren or bracket when hitting enter?

Question

I\'ve been programming Python with Vim for a while but one thing I haven\'t been able to figure out how to do it set it to auto indent to the level of the last open paren.

Answer 1

This can be refined a bit, but should work 99% of the time. Add this in your .vimrc:

function! PythonEnterFunc()
  let l:li = getline('.')
  execute "normal! a\"
  if l:li =~ '([^)]*$'
    let l:pos = stridx(l:li, '(') + 1
    for i in range(l:pos)
      execute "normal! a\"
    endfor
  endif
endfunction

au FileType python inoremap  :call PythonEnterFunc()a
