Subject: Is zsh's 'getopts' correctly implemented?
Date: Sun, 23 Jun 1996 09:34:35 -0700 [thread overview]
Message-ID: <960623093438.ZM12901@candle.brasslantern.com> (raw)
I ask because zsh doesn't recognize OPTERR=0 to silence warnings; and
because in bash the "silent error reporting" of placing a ? in the named
variable and a : in OPTARG, happens whether or not a leading : appears in
the optstring. That is, a leading : should be equivalent to OPTERR=0,
and should have no effect other than silencing the diagnostics; the lack
of a : should not affect the settings of the named variable and OPTARG.
If the difference is intentional for some reason, it's no big deal.
However, I think this is a bug:
zsh% getopts a:b -a -x
zsh: not an identifier: -a
zsh% echo $OPTIND
2
I don't think OPTIND should be incremented in this case. (Bash actually
assigns ? to a variable named "-a", which is even worse.)
Another incompatibility:
zsh% getopts a:b foo -a -x
zsh% echo $foo
a
zsh% echo - $OPTARG
-x
bash% getopts a:b foo -a -x
-bash: illegal option -- x
