vim - 如何使用\打开或关闭NERDTree和标签栏？

Question

我希望<leader>\在以下情况下打开或关闭NERDTree和Tagbar:

仅当NERDTree和Tagbar都打开时才关闭

如果NERDTree和Tagbar已关闭，或者已经打开，则同时打开

到目前为止，在VIMRC中，我有:

nmap <leader>\ :NERDTreeToggle<CR> :TagbarToggle<CR>

哪一个完全不起作用，因为如果一个打开，另一个关闭。它将打开已关闭的一个，并关闭已打开的一个。

如何做到这一点？

您需要使用一个功能来检查插件窗口是否打开，然后采取相应的措施。这应该可以工作，并且还会跳回到您在其中开始的窗口:

function! ToggleNERDTreeAndTagbar()
    let 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
    elseif tagbar_open
        NERDTree
    else
        NERDTree
        TagbarOpen
    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>
