Remap plugin command with plugin command + vim shortcuts

Question

I'm using rails.vim with the command :AS which open the alternate file (like test) and split the window.

The problem is, it's always on the top and I would like to open it below the current window. I would like to know if it's possible to merge these two commands properly?

I'm able to do it with :execute 'AS' | wincmd J but is this the best way to to it?

How can I be sure it goes just below?

And how do I add it to a leader key?

Answer 1

You can do this in different forms.

Use the command you already created and bind this to a mapping (here with the leader key):

nnoremap <leader>as :execute 'AS' <bar> wincmd J<CR>

Or you can create a new command that acts the same way (B for below):

command! ASB :execute 'AS' | wincmd J

But using wincmd J is overwhelming, prefer the split commands :

:abo[veleft] {cmd}
:bel[owright] {cmd}

So you can have your mapping/command like so:

nnoremap <leader>as :bel AS<CR>
command! ASB :bel AS

Note that if you always want to open a split below you can set the option in your vimrc:

set splitbelow
