word-count vim

TheChymera · 技术社区 · 7 年前

我希望vim在状态栏中显示文档总字数(其中显示当前行和字符数)。我也遇到过类似的问题,并尝试了所有提到的建议 here 和 here

为了明确指出一些,我尝试在 ~/.vimrc (ofc随后重启vim):

function! CountNonEmpty()
    let l = 1
    let char_count = 0
    while l <= line("$")
        if len(substitute(getline(l), '\s', '', 'g')) > 3   
            let char_count += 1 
        endif
        let l += 1
    endwhile
    return char_count
endfunction

function WordCount()
  let s:old_status = v:statusmsg
  exe "silent normal g\<c-g>"
  let s:word_count = str2nr(split(v:statusmsg)[11])
  let v:statusmsg = s:old_status
  return s:word_count
endfunction  

" If buffer modified, update any 'Last modified: ' in the first 20 lines.
" 'Last modified: ' can have up to 10 characters before (they are retained).
" Restores cursor and window position using save_cursor variable.
function! LastModified()
  if &modified
    let save_cursor = getpos(".")
    let n = min([15, line("$")])
    keepjumps exe '1,' . n . 's#^\(.\{,10}LOC:\).*#\1' .
          \ ' ' . CountNonEmpty() . '#e'
    keepjumps exe '1,' . n . 's#^\(.\{,10}Word Count:\).*#\1' .
          \ ' ' . WordCount() . '#e'
    call histdel('search', -1)
    call setpos('.', save_cursor)
  endif
endfun

function WordCount()
  let s:old_status = v:statusmsg
  exe "silent normal g\<c-g>"
  let s:word_count = str2nr(split(v:statusmsg)[11])
  let v:statusmsg = s:old_status
  return s:word_count
endfunction
set statusline=wc:%{WordCount()}

或者

function! WordCount()
   let s:old_status = v:statusmsg
   let position = getpos(".")
   exe ":silent normal g\<c-g>"
   let stat = v:statusmsg
   let s:word_count = 0
   if stat != '--No lines in buffer--'
     let s:word_count = str2nr(split(v:statusmsg)[11])
     let v:statusmsg = s:old_status
   end
   call setpos('.', position)
   return s:word_count 
endfunction
set statusline=wc:%{WordCount()}

或者

let g:word_count="<unknown>"
fun! WordCount()
    return g:word_count
endfun
fun! UpdateWordCount()
    let s = system("wc -w ".expand("%p"))
    let parts = split(s, ' ')
    if len(parts) > 1
        let g:word_count = parts[0]
    endif
endfun

augroup WordCounter
    au! CursorHold * call UpdateWordCount()
    au! CursorHoldI * call UpdateWordCount()
augroup END

" how eager are you? (default is 4000 ms)
set updatetime=500

" modify as you please...
set statusline=%{WordCount()}\ words

假设您的状态行已启用( set laststatus=2 ),如下:

set statusline+=%{wordcount().words}\ words

见 :help wordcount()

如果您绝对需要向后兼容,那么下面的代码在Vim 7.x中可以正常工作,并且可能在早期版本中也可以正常工作:

function! WC()
    return len(split(join(getline(1,'$'), ' '), '\s\+'))
endfunction
set statusline+=%{WC()}\ words

可以不过,要更快或更聪明。

字数输入 `vim-airline`

字数由提供 vim-airline 对于许多文件类型,在编写时: asciidoc, help, mail, markdown, org, rst, tex ,text

如果字数未显示在 维姆航空公司 at least for now ,复合文件类型 markdown.pandoc 不被认可为了字数。这可以通过修改 .vimrc 具体如下:

let g:airline#extensions#wordcount#filetypes = '\vasciidoc|help|mail|markdown|markdown.pandoc|org|rst|tex|text'
set laststatus=2    " enables vim-airline.

\v 语句重写默认值 g:airline#extensions#wordcount#filetypes 变量。最后一行确保已启用。

如果有疑问 &filetype 在发出以下命令时返回打开的文件的:

:echo &filetype
