(g)vim - NerdTree和标题栏在彼此上方，留给编辑的文件？

Question

是否有机会让(g)vim将NerdTree和标题栏显示在彼此之上，留给编辑的文件？

+-----------+-------------+
| nerd tree | edited file |
| contents  |             |
+-----------+             |
| tagbar    |             |
| contents  |             |
+-----------+-------------+

我想以某种方式用.vimrc来做。

到目前为止，我的.vimrc中的相关部分如下所示：

" NERDTree shortcut
:nmap \e :NERDTreeToggle<CR>
" tagbar settings
let g:tagbar_left=1
nnoremap <silent> <F9> :TagbarToggle<CR>

然而，当显示时，它们会如下所示：

+----------+-----------+-------------+
| tagbar   | nerd tree | edited file |
| contents | contents  |             |
|          |           |             |
|          |           |             |
|          |           |             |

Answer 1

那会很困难的。:NERDTreeToggle和:TagbarToggle都在内部使用:vsplit，没有办法简单地重新配置或连接到它。

您必须为您的\e和<F9>触发器编写包装器，以检测当前窗口布局，进行切换，然后左右摆动窗口以满足您的需求。仅最后一步就已经相当复杂了。您必须按下一个侧边栏窗口与:wincmd J，然后使正确的文件窗口完全高度再次赢得:wincmd L。

你看，这不容易。我所做的是，总是只有其中一个插件是活跃的。我的个人映射检查打开的侧边栏，在切换NERD_tree之前关闭例如Tagbar。实现起来要容易得多。

Answer 2

在“如何用\打开或关闭NERDTree和Tagbar？”问题中，我使用了Jan编写的vim函数。并修改它(我只添加了wincmd命令)，使我的vim看起来如下：

+-----------+-------------+ 
| Tagbar    |    file     |
| contents  |             |
+-----------+             |
| NERDTree  |             | 
| contents  |             |
+-----------+-------------+

功能！ToggleNERDTreeAndTagbar()让w:jumpbacktohere =1

" Detect which plugins are open
if exists('t:NERDTreeBufName')
    let nerdtree_open = bufwinnr(t:NERDTreeBufName) != -1
else
    let nerdtree_open = 0
endif
let tagbar_open = bufwinnr('__Tagbar__') != -1

" Perform the appropriate action
if nerdtree_open && tagbar_open
    NERDTreeClose
    TagbarClose
elseif nerdtree_open
    TagbarOpen
    wincmd J
    wincmd k
    wincmd L
elseif tagbar_open
    NERDTree
    wincmd J
    wincmd k
    wincmd L
else
    NERDTree
    TagbarOpen
    wincmd J
    wincmd k
    wincmd L
endif

" Jump back to the original window
for window in range(1, winnr('))
    execute window . 'wincmd w'
    if exists('w:jumpbacktohere')
        unlet w:jumpbacktohere
        break
    endif
endfor  
 endfunction
 nnoremap <leader>\ :call ToggleNERDTreeAndTagbar()<CR>
