weird expansion and compctl for man pages

weird expansion and compctl for man pages

[Will Yardley]

two questions.

i use the following to put the current command in the titlebar:

case $TERM in
        (xterm*)
                precmd () {print -Pn "\e]2;%n@%m  %~ %l %W  %T\a"}
                preexec () {print -Pn "\e]2;%n@%m  $*  %l %W  %T\a"}
        ;;
esac

and the following to expand common hostnames and usernames for ssh:

compctl -k hosts -x 'c[-1,-l]' -k usernames -- \
        + -k usernames -S '@' -x 'n[1,@]' -k hosts -- ssh

when ssh to a particular machine was freezing today, i noticed that if i
hit tab while expanding the hostname, the resulting command which showed
up in the titlebar was:
ssh machine ssh machine ssh machine ssh machine

i realize this isn't a super big deal, but is there an easy way to get
around this?

also i tried some of the various compctl scripts for completing man
pages (including the two on the main info site) and neither seemed to
work (i used the bsd option).  i'm using zsh 4.0.1 on freebsd
4.3-stable.  does anyone have a working script on a similar system? 
basically i want to be able to type:
man
and then tab complete to various programs as long as there's a man page
for them
so man l[tab] would expand to ls, lsof etc.

Check the docs for preexec.  $* is no longer what you want;
you'll want to replace that with either $1, $2, or $3.

You may want to try out

autoload -U compinstall ; compinstall

and see if that doesn't make your life easier.
