With the following code in your vimrc, you can press F3 in normal mode to switch between several different status lines.

"These three functions are just for example.
"It might be that these three functions are irrelevant
"in example statuslines, but they demonstrate that
"functions can be used in statusline too.
fu! Percent()
  let byte = line2byte( line( "." ) ) + col( "." ) - 1
  let size = (line2byte( line( "$" ) + 1 ) - 1)
  return (byte * 100) / size
endf

fu! FileEncoding()
  if &fileencoding == ''
    return "is not set"
  else
    return &fenc
  endif
endf

fu! GlobalEncoding()
  if &fileencoding == ''
    return "is not set"
  else
    return &enc
  endif
endf

"And now the magical stuff!
"We define some statuslines at first.
let g:StatusLines{0}='[%1*%n%*]%= [%2*%03bD%* | %2*%5(0x%02BH%)%*] [%8oC=%1*%3{Percent()}%%%*] [%8c] : [%8l/%8L = %1*%3p%%%*]'
let g:StatusLines{1}='[%1*%n%*]%= [%1*GENC%* %10(%{GlobalEncoding()}%)] [%1*FENC%* %10(%{FileEncoding()}%)]'
let g:StatusLines{2}='[%1*%n%*]%= [%1*%F%*]'
let g:StatusLinesCurrent=-1

"And we map switching on some unused key.
map <F3> :call ToggleStatusLine()<CR>

"Function that switch between several statuslines
fu! ToggleStatusLine()
  let g:StatusLinesCurrent=g:StatusLinesCurrent+1
  if (!exists("g:StatusLines" . g:StatusLinesCurrent))
    let g:StatusLinesCurrent=0
  endif
  let &statusline=g:StatusLines{g:StatusLinesCurrent}
endf

"We use the first one as default.
call ToggleStatusLine()

"Because I used some highlighting in the example statuslines
"I put some highlighting definitions here too.
"The colours of statusline itself.
hi statusline term=inverse,bold cterm=inverse,bold ctermfg=darkred ctermbg=white
hi statuslinenc term=inverse,bold cterm=inverse,bold ctermfg=gray ctermbg=black

"Some other colours used in statuslines.
hi User1 term=inverse,bold cterm=inverse,bold ctermfg=darkred ctermbg=yellow
hi User2 term=inverse,bold cterm=inverse,bold ctermfg=darkred ctermbg=cyan

This tip should be useful if you need more information than is able to be fit in a single statusline.

CommentsEdit

If you don't like highlighting on the status line, here is a simpler version (it's just s/%[12]\?\*//g)

let g:StatusLines{0}='[%n]%= [%03bD | %5(0x%02BH%)] [%8oC=%3{Percent()}%%] [%8c] : [%8l/%8L = %3p%%]'
let g:StatusLines{1}='[%n]%= [GENC %10(%{GlobalEncoding()}%)] [FENC %10(%{FileEncoding()}%)]'
let g:StatusLines{2}='[%n]%= [%F]'

I get '[GENC] is not set] [FENC is not set]' on my status line. Also the highligthing is disconcerting, it should be a solid separator line.


A bit better version is this one - works for me fine.

let g:StatusLines{0}='%5* %*->%7*[%*%1*%n%*%7*]%* %= %7*[%*%2*%03bD%* %7*|%* %2*%5(0x%02BH%)%*%7*]%* %7*[%*%3*%8oC%*%7*=%*%1*%3{Percent()}%%%*%7*]%* %7*[%*%4*%8c%*%7*]%*
let g:StatusLines{1}='%5* %*->%7*[%*%1*%n%*%7*]%* %= %7*[%*%1*ENC%* %2*%10{strlen(&enc)?&enc:"is not set"}%*%7*]%* %7*[%*%1*FENC%* %3*%10{strlen(&fenc)?&fenc:"is not set"
let g:StatusLines{2}='%5* %*->%7*[%*%1*%n%*%7*]%* %= %7*[%*%1*FILE%* %*%2*%t%*%7*]%*'
let g:StatusLinesCurrent=-1

fu! SetStatusLineColors()
  hi statusline term=inverse,bold cterm=inverse,bold gui=inverse,bold ctermfg=darkblue ctermbg=white guifg=darkblue guibg=white
  hi statuslinenc term=inverse,bold cterm=inverse,bold gui=inverse,bold ctermfg=darkblue ctermbg=darkblue guifg=darkblue guibg=darkblue
  hi User1 term=inverse,bold cterm=inverse,bold gui=inverse,bold ctermfg=darkblue ctermbg=darkyellow guifg=darkblue guibg=darkyellow
  hi User2 term=inverse,bold cterm=inverse,bold gui=inverse,bold ctermfg=darkblue ctermbg=darkcyan guifg=darkblue guibg=darkcyan
  hi User3 term=inverse,bold cterm=inverse,bold gui=inverse,bold ctermfg=darkblue ctermbg=darkmagenta guifg=darkblue guibg=darkmagenta
  hi User4 term=inverse,bold cterm=inverse,bold gui=inverse,bold ctermfg=darkblue ctermbg=darkgreen guifg=darkblue guibg=darkgreen
  hi User5 term=inverse,bold cterm=inverse,bold gui=inverse,bold ctermfg=darkblue ctermbg=darkblue guifg=darkblue guibg=darkblue
  hi User6 term=inverse,bold cterm=inverse,bold gui=inverse,bold ctermfg=darkblue ctermbg=darkred guifg=darkblue guibg=darkred
  hi User7 term=inverse,bold cterm=inverse,bold gui=inverse,bold ctermfg=darkblue ctermbg=black guifg=darkblue guibg=black
endf

fu! ToggleStatusLine()
  call SetStatusLineColors()
  let g:StatusLinesCurrent=g:StatusLinesCurrent+1
  if (!exists("g:StatusLines" . g:StatusLinesCurrent))
    let g:StatusLinesCurrent=0
  endif
  let &statusline=g:StatusLines{g:StatusLinesCurrent}
endf

This is already builtin, see :help 'statusline':

fu! Percent()
  let byte = line2byte( line( "." ) ) + col( "." ) - 1
  let size = (line2byte( line( "$" ) + 1 ) - 1)
  return (byte * 100) / size
endf
