我可以遍历NERDTree,但要查看文件内容,我按 go ,一旦打开文件缓冲区保持打开状态,直到我明确地关闭它。这使查看文件太不舒服了。
当我遍历NERDTree节点时,我想在临时查看器缓冲区中看到突出显示的文件内容,我想明确选择一些遍历的文件进行编辑,比如按电子
当我关闭NERDTree缓冲区时,临时查看器缓冲区也将关闭,并且只应为那些明确选择的文件打开缓冲区,而不是所有查看的文件。
这可能吗?

看起来这可能是NERDTree的一个很好的功能请求:)
与此同时,您可以将〜/ .vimrc放入以下内容中:
let g:nerd_preview_enabled = 0
let g:preview_last_buffer = 0
function! NerdTreePreview()
" Only on nerdtree window
if (&ft ==# 'nerdtree')
" Get filename
let l:filename = substitute(getline("."), "^\\s\\+\\|\\s\\+$","","g")
" Preview if it is not a folder
let l:lastchar = strpart(l:filename, strlen(l:filename) - 1, 1)
if (l:lastchar != "/" && strpart(l:filename, 0 ,2) != "..")
let l:store_buffer_to_close = 1
if (bufnr(l:filename) > 0)
" Don't close if the buffer is already open
let l:store_buffer_to_close = 0
endif
" Do preview
execute "normal go"
" Close previews buffer
if (g:preview_last_buffer > 0)
execute "bwipeout " . g:preview_last_buffer
let g:preview_last_buffer = 0
endif
" Set last buffer to close it later
if (l:store_buffer_to_close)
let g:preview_last_buffer = bufnr(l:filename)
endif
endif
elseif (g:preview_last_buffer > 0)
" Close last previewed buffer
let g:preview_last_buffer = 0
endif
endfunction
function! NerdPreviewToggle()
if (g:nerd_preview_enabled)
let g:nerd_preview_enabled = 0
augroup nerdpreview
autocmd!
augroup END
else
let g:nerd_preview_enabled = 1
augroup nerdpreview
autocmd!
autocmd CursorMoved * nested call NerdTreePreview()
augroup END
endif
endfunction
这可能是非常天真和讨厌的代码,但通过一些调整可以做你想做的事。

我建立了DavidEG的答案,考虑到标签,因为我遇到了多个nerdtree标签边缘案例。
function! PreviewNERDTreeFile()
if !exists('t:previous_preview_buffer') | let t:previous_preview_buffer = 0 | endif
let filename = substitute(getline('.'), '^\s*\|\s*$', '','g')
let should_close_buffer_next_time = 1
if (bufnr(filename) > 0) | let should_close_buffer_next_time = 0 | endif
normal go
if t:previous_preview_buffer > 0
exe 'bwipeout ' . t:previous_preview_buffer
let t:previous_preview_buffer = 0
endif
if should_close_buffer_next_time
let t:previous_preview_buffer = bufnr(filename)
endif
endfunction

这是一个 NERDTree 扩展,它使用最后一个活动缓冲区作为预览窗口,并根据您是否使用 o, s, i, gs, gi
等打开来劫持该窗口或将其与原始内容分开。
