Subject: PATCH: $history index in prompt_bart_precmd
Date: Sat, 8 Apr 2000 20:55:14 +0000 [thread overview]
Message-ID: <1000408205514.ZM22397@candle.brasslantern.com> (raw)
I finally exceeded my $HISTSIZE in one window and noticed that my prompt
was no longer updating. $history behaves as an assoc indexed on the
current history number, which means it gets leading empty elements as
things fall off the front -- but $#history reflects the actual number of
non-empty elements, e.g. it's never more than $HISTSIZE-1.
There is, however, some kind of bug with interpretation of the keys for
$history, because e.g. $history[3-1] == $history[3]. (It should yield
the empty string, as there isn't any hash table value for key "3-1".)
