:let @/ = "the"

6. 格式化文本 formatting

:nnoremap Q gq

gqap

gwap

setlocal formatexpr=xmlformat#Format()

func! format#Format()
  " only reformat on explicit gq command
  if mode() != 'n'
    " fall back to Vim's internal reformatting
    return 1
  endif
  let lines = getline(v:lnum, v:lnum + v:count - 1)
  call map(lines, {key, val -> substitute(val, '\s\+$', '', 'g')})
  call setline('.', lines)
  " do not run internal formatter!
  return 0
endfunc

setlocal formatexpr=format#Format()

:set comments=f:->,f:-

sr:/*,mb:*,ex:*/

:set comments=sr:/***,m:**,ex-2:******/

                                  /*** ~
                                    **<--right aligned from "r" flag ~
                                    ** ~
offset 2 spaces for the "-2" flag-->** ~
                                  ******/ ~

"b:*"        Includes lines starting with "*", but not if the "*" is
             followed by a non-blank.  This avoids a pointer dereference
             like "*str" to be recognized as a comment.
"n:>"        Includes a line starting with ">", ">>", ">>>", etc.
"fb:-"        Format a list that starts with "- ".

1. the first item
   wraps
2. the second item

        first line of a paragraph
second line of the same paragraph
third line.
