如何用<leader> \打开或关闭NERDTree和Tagbar？

Question

我想<leader>\在以下条件下打开或关闭NERDTree和Tagbar:

1. 如果NERDTree和Tagbar都打开,则仅关闭两者
2. 如果NERDTree和Tagbar关闭或者如果已打开,则打开两者

到目前为止,在VIMRC,我有:

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

这不正确,因为如果一个打开,另一个关闭.它将打开关闭的那个并关闭打开的那个.

怎么能实现这一目标？

您需要使用一个函数来检查插件窗口是否打开,然后相应地执行操作.这应该可以工作,也会跳回到你开始的窗口:

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>
