Subject: Set option in parent after emulate -L zsh
Date: Thu, 09 Mar 2017 00:58:56 -0800	[thread overview]
Message-ID: <1489049936.3120661.905537968.237F11E3@webmail.messagingengine.com> (raw)

Hello,
doing:

% unsetopt promptsubst   # Should see garbage in prompt
% () { setopt promptsubst; }

restores correct prompt. Then, to handle emulate -L:

emulate -L zsh
unsetopt promptsubst
() { setopt promptsubst; }   # no change
() { unsetopt localoptions; setopt promptsubst; }   # prompt restored
echo $options[localoptions] $options[promptsubst]   # shows "on on"

I wonder what does the "unsetopt localoptions" do. It connects current
function's level with parent locallevel in context of options, not
harming parent "localoptions" setting? That would be the best
possibility, but I'm afraid something different might be happening
maybe?
