Subject: Subscript of negatively-subscripted array element gives incorrect result
Date: Thu, 25 Mar 2004 19:56:00 -0600 [thread overview]
Message-ID: <200403251956.00439.jonathan-hankins@mindspring.com> (raw)
Hi,
I reported this previously through the Bugs section on the Sourceforge page
for zsh, but wasn't sure if it was active. I also have a bit more
information.
I am getting different results taking a substring of the same array element
when I index it negatively than when I index it positively. Here is an
example:
These are correct:
% t=(foo bar baz)
% print ${t[2]}
bar
% print ${${t[2]}[1]}
b
% print ${${t[2]}[1,2]}
ba
% print ${${t[2]}[2]}
a
% print ${${t[2]}[2,3]}
ar
%
This is also correct:
% print ${t[-2]}
bar
These are not correct:
% print ${${t[-2]}[1]}
bar
% print ${${t[-2]}[1,2]}
bar
% print ${${t[-2]}[2]}
% print ${${t[-2]}[2,3]}
%
Those last 2 yield an empty string.
I verified this behavior with 4.0.4, 4.0.9, 4.1.1 and 4.2.0 on a Debian
GNU/Linux system.
Thanks!
