Vim is a text editor based off the classic vi editor. It is different from other text editors in that it has different modes of operation. You can learn about vim through various websites.

Vim is a very capable editor for mobile devices because of its low footprint and efficiency of key strokes.

[edit] Installation

Vim can be installed from the extras repository.

[edit] Configuration

Vim can be configured through the ~/.vimrc file. Here are some items that make it easier to use vim on the N900. 

" Map the comma key to colon
map , :


" Press jj while in insert mode to press escape
inoremap jj <esc>


" CTRL+Up to page up, CTRL+Down to page down
map <c-up> <c-u>
map <c-down> <c-d>


" Use 256 colors
set t_Co=256

" Ctrl-Space (layout switcher) does nothing
imap <Nul> <Nop>
map <Nul> <Nop>
vmap <Nul> <Nop>
cmap <Nul> <Nop>
nmap <Nul> <Nop>

[edit] Finger scrolling

Add the following to your ~/.vimrc to enable scrolling by dragging the screen. 

" Drag scrolling. Taken from the ez_scroll vim script
" http://www.vim.org/scripts/script.php?script_id=3141

func! MScroll()
  let l:done=0
  let l:n = -1
  let l:w0 = line("w0")
  let l:last = line("$")
  while done!=1
    let l:g = getchar()
    if l:g != "\<LeftDrag>"
      let done = 1
    else
      if l:n == -1
        let l:n = v:mouse_lnum
        let l:fln = v:mouse_lnum
      else
        let l:new = l:w0 - v:mouse_lnum + l:n
        if l:new<1
          let l:new = 1
        endif

        let l:diff = -v:mouse_lnum + l:n
        let l:nd = line("w$")
        if l:nd+l:diff>l:last
          let l:new = l:last - winheight(0) + 1
          if l:new<1
            let l:new = 1
          endif
        end

        let l:wn = "normal ".string(l:new)."zt"
        if (l:n != v:mouse_lnum)
          exec(l:wn)
          redraw
        endif
        let l:w0 = line("w0")
        let l:n = v:mouse_lnum + l:diff
      endif
    endif
  endwhile
  :call cursor(v:mouse_lnum,v:mouse_col)
endfunc
:set mouse=a
:noremap <silent> <LeftMouse> :call MScroll()<CR>
:noremap <LeftRelease> <Nop>
:noremap <LeftDrag> <Nop>
