Move/Duplicate text intuitively.

Move selected lines or block area to specified direction ( up/down/right/left ).
Duplicate selected lines or block to specified direction ( up/down/right/left ).
Two mode: inesrt or replace
Count support
Keep original cursor position (include 'o'ther pos in visualmode!) while moving / duplicating.
Undo with one 'u' by undojoining.

Experimental hook/helper

Currently only finish hook point is supported. finish is called just before manipulation finish. If you want to additional text manipulation, you can start from following example. The hook must accept one argument(tm in this example), which is texmanip app instance itself.

let g:textmanip_hooks = {}
function! g:textmanip_hooks.finish(tm)
  let tm = a:tm
  let helper = textmanip#helper#get()
  if tm.linewise
    " if filetype is `html` automatically indent
    if &ft ==# 'html'
      call helper.indent(tm)
    endif
  else
    " When blockwise move/duplicate, remove trailing white space.
    " To use this feature without feeling counterintuitive,
    " I recommend you to ':set virtualedit=block',
    call helper.remove_trailing_WS(tm)
  endif
endfunction
