Subject: How to substitute empty array element, or empty string
Date: Wed, 22 Mar 2017 08:52:09 +0100 [thread overview]
Message-ID: <etPan.58d22d29.6b8b4567.10ab3@MacMini.local> (raw)
Hello,
following does not work as expected:
% a=( a "" c ); print -rl -- "${(@)a//*/x}”
x
x
% a=""; print -rl -- "${a//*/x}”
(empty line)
I guess this is inherited from // substitution. I count lines using substitution that matches (*), and it is skipping empty lines, giving wrong line number for following elements.
Is there any solution? I’ve tried (#s), (#s)(#e), *(#e) and nothing.
