有没有一种方法可以映射特定于插件的键在Vim中做多个键？

Question

I'd like to map NERDTree's tab opening key, 't', to do multiple things. Namely, I'd like it to open the tab then do the following list of commands: TlistToggle Ctrl W, Ctrl T, Ctrl W, Shift K, 30, Ctrl W, minus-sign. So that I open the taglist for the file, then horizontally split the list and the file, then resize the tag list.

I've tried the following:

nnoremap <t> NERDTree-t TlistToggle <C-W><C-T><C-W><S-K>30<C-W> -

but this doesn't seem to do anything.

Thoughts? Am I just completely doing this wrong. Is this even possible?

Answer 1

• The NERDTree mapping is not a global one, but only exists (and makes sense) in the plugin's sidebar. That makes it more difficult to override, but you can hook into NERDTree setting its 'filetype' , and then define a buffer-local mapping to override NERDTree's:

  :autocmd FileType nerdtree nnoremap t ...

• While normal mode commands (like the <Cw>... stuff) can indeed be concatenated, that's not true for the plugin invocations. You can find out NERDTree's via :nmap <buffer> t :

  :call nerdtree#invokeKeyMap("t")

The Taglist's is also an Ex command; you can combine both with | (written as <Bar> in mappings):

:call nerdtree#invokeKeyMap("t")<Bar>TlistToggle<CR>

So, something like this should work (I didn't test it):

:autocmd FileType nerdtree nnoremap <buffer> t :call nerdtree#invokeKeyMap("t")<Bar>TlistToggle<CR><C-W><C-T><C-W>K30<C-W>-

Answer 2

Here is the final solution I used to open a file in new tab from NERDTree and then split and resize the file & TlistToggle:

autocmd FileType nerdtree nnoremap <buffer> t :call nerdtree#ui_glue#invokeKeyMap("t")<CR> :TlistToggle<CR> <C-w><C-t><C-w>K :exe "resize " . ((winheight(0) + winheight(1)) * 3/20)<CR>

And this resizes the tag list that was opened in a horizontal tab by 15% of the total amount of lines in the whole window.
