zsh: Command not found (for $EDITOR)
For whatever reason, zsh doesn't like me setting command-line arguments for my $EDITOR variable, but from what I can tell, it's not supposed to be this way. I've seen people use
export EDITOR='open -Wn'
in their ~/.zshrc file, but when I try to do that, I just get a complaint.
zsh: command not found: open -Wn
Any reason why this might be happening? Setting the $EDITOR to 'mate', 'vim' or 'open' seems to work just fine, but 'mate -w' and 'open -Wn' don't work.
I'm running zsh inside screen on Mac OS X, and my ~/.zshrc is as follows:

Answer
In zsh, when you write $EDITOR, it expands to a single word. Unlike other Bourne-style shells, zsh does not split words when it expands unquoted expansions. You can make it happen with the
= modifier on parameter expansion.
$=EDITOR $file
A more portable method is to ensure that EDITOR does not contain any space. Most applications treat $EDITOR as a shell snippet or as a whitespace-separated list of words, but I've encountered a few that treat it as a command name. Make EDITOR point to a shell script.
% cat ~/bin/EDITOR
#!/bin/sh
open -Wn -- "$@"
% grep EDITOR ~/.profile
export EDITOR=~/bin/EDITOR
