blah*[TAB] (difference between 3.1.6 and 3.1.9)

blah*[TAB] (difference between 3.1.6 and 3.1.9)

[Vincent Lefevre]

Consider a directory where there are two files blah1 and blah2. With
zsh 3.1.6, when I typed blah* followed by a tab, "blah1 blah2 " was
generated (with a space after blah2). With zsh 3.1.9, "blah1 blah2"
is generated (with *no* space after blah2).

How can I have the old behavior (much more logical IMHO)?

Something's definitely gone wrong with expand-or-complete.  This was not
intentional.

As a workaround, the following should behave the way you want:

bindkey '\t' complete-word
autoload -U compinit
compinit
zstyle ':completion:*' completer _expand _complete
zstyle ':completion:*:expand:::' glob 1
zstyle ':completion:*:expand:::' substitute 1

If you have some customized compctl commands, you may also want:

zstyle ':completion:*' use-compctl 1

The above consititutes pretty much the minimal set of commands to emulate
the default behavior of expand-or-complete in 3.1.6 and earlier versions
while using the new completion system.

If I use this (at the end of my .zshrc), variable names completion
doesn't work any longer. For instance, I type "echo $ZSH_V":

Et encore? echo $ZSH_V

then [TAB], and I get:

Et encore? echo #
         $ZSH_V

where '#' represents the cursor.

configuring the new completion system

This comes close, but there's still something about this setup that
annoys the heck out of me.  (I'm only just beginning to try to get the
new completion system working (since I have mainly been using a
customized version of 3.0.7 until just recently), so hopefully this
can be tweaked.)

My biggest gripe is that if I type "~/.z" or "$HOME/.z" and press tab,
the prefix expands into my home directory path.  I *hate* this.  I'm
typing an abbreviated directory path and I want to complete an
abbreviated directory path.  When I remove the "_expand" portion of
the zstyle, then that part of the completion works properly, but I can
no longer expand "~/.z*" into a list of file names.  I would love to
see a version of _expand that works like it did in 3.0.x.

On a related note, I've always disliked the fact that wildcard
expansion expands variables and tilde references.  For instance, if I
type:

    touch ~/.tmp{1..3}
    rm ~/.tmp*<tab>

I want to see:

    rm ~/.tmp1 ~/.tmp2 ~/.tmp3

not:

    rm /home/wayne/.tmp1 /home/wayne/.tmp2 /home/wayne/.tmp3

I've always been meaning to look into fixing this.  I figure that the
code can either keep a copy of the unexpanded strings to substitute
into, or that it can do a set of reverse substitutions after the
wildcard expansion has completed (e.g. turning "/home/wayne" back into
a "~" at the tail end of the process).

Finally, one of the just-committed cvs changes has introduced a bug
where an extra space is getting added when it shouldn't be.  Now, if
you type "~/.z<tab>" you get "/home/wayne/.z " even though that file
does not exist.  You should be able to reproduce this as follows:

% zsh -f
% autoload -U compinit
% compinit
% zstyle ':completion:*' completer _expand _complete
% zstyle ':completion:*:expand:::' glob 1
% ls ~/.z<tab>

I think you want to NOT rebind '\t' to complete-word -- that is, leave it
bound to expand-or-complete -- AND leave out the _expand completer.  This
will give you the old behavior of expansion followed by the new behavior
of completion.

You can still get the new behavior of _expand from <C-x e> in this case.

You could also ignore the recommendation in the manual, and do this:

    bindkey '\t' expand-or-complete
    zstyle ':completion:*' completer _complete _expand

This will first try old-style expansion, and then new-style completion,
and finally (if nothing else has happened yet) new-style expansion.

} expansion expands variables and tilde references.  For instance, if I
} type:
} 
}     touch ~/.tmp{1..3}
}     rm ~/.tmp*<tab>

Unfortunately tilde-references are considered part of filename generation
for purposes of _expand.  Variables are another matter; that's what the
`substitute' style is for.  Set it to 0 instead of to 1, and parameter
expressions (including $(...) etc.) will not be expanded.

} I want to see:
} 
}     rm ~/.tmp1 ~/.tmp2 ~/.tmp3

What's amusing is that _expand behaved this way for a while, but somebody
else complained that he wanted the tildes to expand like they do with
expand-or-complete.

However, there's also the `completions' style:

    zstyle ':completion:*:expand:*' completions 1

If you set that style and do

    zsh% rm ~/.tmp<C-x e>

(note no `*') then you'll see what you wanted.  I would not recommend
using that with _expand in the completer style, though.  (If you want to
be able to have the `*' in there, you'll need to setopt globcomplete as
well.)

You could also set the style so that <C-x e> behaves that way ONLY if
the current word begins with a tilde, like so:

    zstyle ':completion:*:expand:*' completions '${(M)#PREFIX#\~}'

The tricky bit is backslashing the tilde there; I'm not sure why that's
required.  Anyway, the value of the completions style is evaluated in
$[...] and if that returns nonzero then instead of expansion, it does
completion, but inserts all possible completions.  So the above says
that if there's a substring that matches ~ at the front of the current
word, then expand all completions, otherwise do expansion as usual.

} 
} % zsh -f

} % compinit

You should use "compinit -D" to test the real default behavior; without
the -D it may load a .zcompdump that isn't up to date.

} % zstyle ':completion:*' completer _expand _complete
} % zstyle ':completion:*:expand:::' glob 1
} % ls ~/.z<tab>

Hmm, you're right, it's one of the *really* recent ones, probably either
11777 or 11776 (I hope not 11768).  I had to re-"make install" to see it.

That would be cool if I could get it to work.  However, no matter
what I try, tab does not expand wildcards with expand-or-complete
set.  It just expands $VARIABLES.

The only thing I get when I do that is this error:

    _expand_word:5: curcontext: parameter not set

This is caused by my predilection to having the "no_unset" option set
for my interactive-shell use.  Seems like this should get turned off
when the shell runs some completion/expansion code.  Do we have an
existing solution for such things?

When I "setopt unset", then the <C-x e> binding is quite handy.  If I
could just re-introduce those old changes to have it stop expanding
tildes, I'd be quite happy.
