Expand from completion

Expand from completion

[GoTaR]

Hi!

I don't remember if I asked it allready, but there is new version
coming, so maybe once more: how to expand sth like this:

~: rpm -qi *devel*[tab]
RPM package
ORBit-devel-0.5.17-2                  esound-devel-0.2.29-1      libstdc++-devel-3.2.2-0.5
SDL-devel-1.2.5-4                     expat-devel-1.95.6-2       libtiff-devel-3.6.0-0.beta.1
[...]

? I'd like to bring all matches to command line:

~: rpm -qi ORBit-devel-0.5.17-2 SDL-devel-1.2.5-4 \
	esound-devel-0.2.29-1 expat-devel-1.95.6-2 \
	libstdc++-devel-3.2.2-0.5 libtiff-devel-3.6.0-0.beta.1 [...]

For files it works with ^x-* (or with some style/sth with tab).

Sounds like you want to use the _all_matches completer, probably in
combination with _match. _all_matches should go at the beginning of the
list of completers, before _complete or _match.

If you want it to be bound to a key instead of part of the things tab
will do, create a new widget using _generic:
  zle -C all-matches complete-word _generic
  bindkey '^Xx' all-matches
  
Then put `all-matches' in the widget part of the context for any styles
you want to set. As a minimum, you'll need to set the completer style:
  zstyle ':completion:all-matches::::' completer _all_matches _complete _match

I can't reproduce that problem so I'm not sure.

When I wanted to do that myself, I added the insert style to
_all_matches but that change is only in zsh 4.1. So in 4.1, you can do:
  zstyle ':completion:all-matches:*' insert true

If you want to stick with 4.0, you could probably just take the
_all_matches patch from 16923 and put the modified _all_matches
somewhere early in your $fpath.

I also find it useful to set:
  zstyle ':completion:all-matches:*' old-matches true
so that if an existing list is displayed, perhaps from a different
completer, I can press ^Xx and it will insert all the matches from the
existing list.
