Subject: code that used to work that doesn't anymore
Date: Sun, 22 Feb 2015 22:07:24 +0100 [thread overview]
Message-ID: <CAHYJk3QKsGYhjM8a6-sMqVimzkyuxHbz61MfHLAEhcY4EZW1uw@mail.gmail.com> (raw)
No idea if this was meant to be valid syntax, but used to run:
% zselect -t ${$(( $1 * 100 ))%.[0-9]#}
zsh: bad substitution
This works both now and before:
% zselect -t ${${:-$(( $1 * 100 ))}%.[0-9]#}
NB: this is perhaps the most unexpected result of my life
% echo ${:-$[5]}
5
% echo ${$[5]}
7
But it's simply element five of $$ (pid of zsh).
I guess the ${$ in my first command is now interpreted as a $$ and
then the (( is nonsense?
