globbing

[Will Yardley]

well i'm sorry if this is a dumb question, but i really did rtfm... just
haven't been able to figure this one out for a while....

in bash if it hit
% cd /home/* and hit tab, it just sits there (although i can tab complete
other stuff)

in zsh, it'll split out the whole list unless i put the slash after the
asterisk, which can get pretty messy

% cd /home/abuse /home/andrewh /home/ben /home/brad /home/brett /home/brian
/home/charis /home/dadmin ...... and so on and so forth

glob_complete is almost what i want, only ideally i'd like it to not display
the entire array.

i think the second question has been brought up before, but is there a way to
do:
% cd /usr/l<tab>bin
and have that complete to /usr/local/bin as in bash (without putting a space
after /usr?

i do have complete_in_word set, but that's not exactly the same thing...

i love zsh, but there are a few little things that i still haven't been able
to aproximate.  i'm sure i'll get over it eventually....

Can you be more precise? You want complete glob patterns but do not want
to see completion list? You do not want to see completion listing always
or only in case of completing patterns?

To switch listing off use setopt nolist and probably nomenu, noautomenu.
I guess you know it. To switch list off only for patterns you need to
use new completion and set styles something like ...

... Oops! I was about to say that you need to use

zstyle ':completion::match:*' list off

But I realized that listing is not controlled by style. How weird.
Actually, according to documentation, the

zstyle ':completion::match:*' menu off

must work but does not.

What's the difference?

Why do you want to do it "bash style" with zsh? E.g. using zsh it is
much better to do

ls /u/l/bTAB

and get it completed to /usr/local/bin. Easier, is not it?

Of course. Use complete-word instead of expand-or-complete:

bindkey '^I' complete-word

It will totally ignore any patterns and try to complete "as is". But 
note that new completion gives you choices between completion, matching 
and expansion and you can select the order in whch it happens and and 
and ...

If it is the sole reason to use prefix completion - my example does it 
as well. It does better job than bash - it checks suffix as well and 
won't try to complete prefix if the whole completion would fail. Wit zsh 
you can do:

cd /u/bTAB
It completes to /usr/bin - you realise you made a mistake. Press Undo 
(^_ or ^Xu by default). You get inital line. Go back, add `l/' like in

cd /u/l/TABb

and it will be completed to /usr/local/bin. But *only* if /usr/local/bin 
exists. And it will move cursor to the end if you have the single choice 
or to the first ambiguous place if you have multiple choices. And this 
is configurable as well :-)

You have to use expand-or-complete-prefix instead of expand-or-complete 
(or complete-word), like

bindkey '^I' expand-or-complete-prefix
setopt completeinword

But then your first problem is back - there is no complete-prefix widget.
  It is unlikely that any will be added - new completion can do 
everything you want and with much better configuration possibilities. 
(modulo bugs, as looks there are with menu and list styles)

}

} setopt completeinword
}

You can, however, roll your own (but not in 3.0.x):

  bash-complete () {
    emulate -L zsh
    if [[ $RBUFFER = (|[[:space:]\;\&\|\>]*) ]]
    then
      zle complete-word         # Completing at end of word is not special
    else
      setopt noautomenu         # Cannot menu-complete the prefix, sorry
      RBUFFER[1]=" $RBUFFER[1]" 
      zle complete-word                  
      RBUFFER[1,2]=$RBUFFER[2]           
      if [[ $LBUFFER[-1] = $RBUFFER[1] ]]
      then
	LBUFFER[-1]=''          # Suppress doubled slashes, for example
      fi
    fi
  }
  zle -N bash-complete
  bindkey '\t' bash-complete

This could, I suppose, get added to the collection of bash-alike functions
that PWS has created.  It does appear to work with `setopt bashautolist'.

That works _exactly_ how I wanted it to. Perhaps the normal way is better,
but old habits die hard.... thanks for going to the trouble of writing that
function too!

Now you see why it is better to keep discussion on the list :-)

Have you tried the _match completer? If you don't want the entire array
displayed, what do you want displayed?

The _prefix completer is probably what you want then. It ignores the
suffix. It seems to work in the same way as bash to me. So try:
    zstyle ':completion:*::::' completer _match _prefix _complete
making sure you leave the completeinword option set.

[Tyler Spivey]

How can I get this to work? I want to read a filespec from the user,
then expand it into an array from a variable. e.g. (nonworking code):
f=\*
a=($f)
This should work, since a=(*) will work.
How can I force filename generation?
Thanks,
Tyler
