In a previous question I asked about outputting evaluated code to a new window in MacVim. I got a great solution, but it presented another question: How can I map a key command in my
.vimrc that involves piping output in the shell?
As a simple example, let's say I wanted to pipe the results of
ls -a to a new MacVim window. From the Vim command line I can enter
!ls -a | mvim -, and the results will appear in a new window. Great! Now, I add that to my
nmap <Leader>r :w !ls | mvim -<CR>
Vim now throws an error every time I try to source my
.vimrc, which reads as follows:
E492: Not an editor command: mvim -<CR>
Any ideas on how to overcome this?
