Create a command shortcut for NERDTree in Vim editor

Question

I'd like to create an abbreviation for NERDTree on the command-line. I find it annoying have to write :NERDTree every time I want to enable it. So I'd like to type :nr or something like that. Is that possible?

Note: Vim doesn't let you add custom commands that start with a lowercase. For Instance, ':ne' would not be valid, but ':Ne' would be. – Photocell

Answer 1

In my .vimrc I have:

let mapleader = ","
nmap <leader>ne :NERDTree<cr>

So when I need NERDTree I just write ,ne in normal mode.

If you want do it like in your question, then add to .vimrc: :command NE NERDTree. Than you can call it: :NE – Fact

Thanks! I've been using nmap <leader>ne :NERDTreeToggle<cr> to toggle NERDTree on and off. – Archuleta

Why isn't this a default =( – Wera

It would be nice is this focused in NERDtree if it was already open. – Wera

@Fact if you have no object, you should make this :NERDTreeFocus so it doesn't open multiple copies. – Wera

Answer 2

I find this works very nicely, better than any other suggestions I've tried:

map <silent> <C-n> :NERDTreeFocus<CR>

You just hit control-n to go back to the hierarchy. Selecting a file name in the hierarchy will switch you, of course, to that file.

1. It works in both normal and insert mode
2. It doesn't close the hierarchy as the accepted answer does (using the :NERDTree command starts you from scratch, closing the hierarchy, while using :NERDTreeFocus simply moves the focus, which I think is what you want)

For me in INSERT mode Control-N was always code completion. And it stil is with this mapping. – Yalonda

Answer 3

To toggle, use the following:

map <silent> <C-n> :NERDTreeToggle<CR>

Answer 5

add to your rc file (.bashrc / .zshrc) this shortcut

alias nerd="nvim -c \"NERDTree\""

then, reload your bash width

source ~/.zshrc # or ~/.bashrc according your case

and run

nerd

the -c flag allows you to execute a command when starting the terminal

nvim -c "command"
