Subject: Odd expansion behavior
Date: Thu, 03 Jul 2014 00:43:23 -0700 [thread overview]
Message-ID: <87pphm51lw.fsf@secretsauce.net> (raw)
Hi.
I'm observing something odd. It might be a bug, but I don't understand
it well-enough to call it that.
I see this:
$ x=(1 2 3); echo xxx${^x}
xxx1 xxx2 xxx3
This output makes sense. However something slightly different is strange:
$ x=(1 2 3); y=xxx${^x}; echo $y
xxx1 2 3
Here the ${^x} form turns on the RC_EXPAND_PARAM option, and it's
apparently not kicking in in the second (broken) case. Even if I setopt
it, I still don't have this working.
I asked on #zsh and osse helpfully pointed out that this can be made to
work by expressing the assignment as 'y=(xxx${^x})' instead, which does
work.
But shouldn't it work the other way as well? osse wasn't sure why the
original form wasn't working, so I'm reporting it here as a maybe-bug.
Thanks
dima
