Subject: PATCH: "typeset -x" acts as if "-g"
Date: Fri, 19 Nov 1999 04:11:45 +0000 [thread overview]
Message-ID: <991119041146.ZM10235@candle.brasslantern.com> (raw)
This change should make "typeset -x" completely equivalent to "export", as
it was before the "-g" option was introduced some while ago. Note that you
still can't export a local, so neither "export FOO" nor "typeset -x FOO"
changes the environment if there's a local FOO in some surrounding scope.
I looked at lifting that restriction in sh/ksh emulation modes, but I need
to find out why the addenv() in restore_params() doesn't do what I expect.
