Dynamic named directories and completion

Dynamic named directories and completion

[Scott Frazer]

I'm trying to use dynamic named directories and have subsequent completion work.

Here is my (perhaps naive) attempt:

zsh_directory_name ()
{
     emulate -L zsh
     setopt extendedglob
     local -a seg;
     seg=(${(s:/:)PWD%/*})
     if [[ $1 = n ]]; then
         typeset -ga reply
         reply=( /${(j:/:)seg[1,(I)$2]} )
     elif [[ $1 = c ]]; then
         local expl
         _wanted values expl 'parent dirs' compadd -S\] -a seg
     else
         return 1
     fi
     return 0
}

Suppose I am in directory /aaa/bbb/ccc/ddd/eee and want to go up to directory
ccc and then down into another directory.  If I do:

cd ~[c<TAB>

it correctly completes to:

cd ~[ccc]

If I hit enter at this point I go to /aaa/bbb/ccc.  So far so good.  If I
try to start completion, like so:

cd ~[ccc]/<TAB>

zsh doesn't give me options for directories under ccc, it thinks '/' is
the command I'm trying to complete.  Is there a way to make this work?

Thanks,
Scott

[RFC PATCH] _path_files: teach zsh_directory_name

Hi, I want this feature, too. It is necessary to tweak _path_files function
as far as I can tell. So, I wrote a patch.

To zsh-workers:
This `elif` clause could be merged with the following `elif` clause because
it starts with \~, too. But it may break something, so I did prepend the
separate `elif` clause for \~\[*.

I don't see anything wrong in your code and for me, it works as you
expect (zsh 5.4.2). Does "echo ~[ccc]" returns the right value?

Yes, "echo ~[ccc]" works correctly.  I'm using zsh 5.3 so maybe there is some
difference there.  Perhaps there is some difference in options/modules/etc.  If
I cut my .zshrc down to a minimum:

autoload -Uz compinit
compinit

zstyle ':completion:*' verbose yes
zstyle ':completion:*' menu select=2
zstyle ':completion:*:messages' format '%d'
zstyle ':completion:*' group-name ''
zstyle ':completion:*' squeeze-slashes true

zstyle ':completion:*:descriptions' format "%UCompleting %d:%u"
zstyle ':completion:*:warnings' format "No matches for: %d"

(with the above zsh_directory_name() too of course), plain ~[whatever] works
but ~[whatever]/ will not complete paths.  Do you have anything non-standard
in your completion?

I would like to do this feature, too.
It is necessary to tweak `_path_files` function as far as I can tell.

There's something screwy here, certainly.  I don't think it should be
necessary to modify _path_files in 5.3, though, there are certainly
cases where you get the right answer, and I think the logic that currently
handles ~ at the start should do the right thing here.

I've a theory it's down to the completion widget in use, i.e. how
completion gets started up.  If instead of hitting tab, you type <Esc>x
complete-word<Enter> --- or instead bind that widget,

bindkey '^i' complete-word

and then use tab --- does it start working?  The default is
expand-or-complete, and I believe the expand bit is nixing the
completion in this case.  (Except we don't really have the word "nix"
this side of the Atlantic, so I may be talking nonsense, but it sounded
good.)

This is all quite complicated so I can well believe it's useful; I don't
think it fixes the behaviour I was seeing (but I may be getting
confused).

On the same theme, I think the following is useful for those of us
using the _expand completer, which may well have nothing whatsoever to
do with the original problem.

Just this patch does not fix the completion issue (I even upgraded to 5.4.2
just to be sure).  Since M-x complete-word does work, I may try looking at
expand-or-complete to see if I can figure out what is happening.  I'm no
zsh expert though, so I will likely need help not breaking something else.

Yes, M-x complete-word does indeed work!  I still need to try some of the
patches from later in this thread ...

Glad it's not totally shrouded in obscurity...

Would generally recommend the combination of complete-word as binding
for tab + use of the expand completer (which I fixed somewhere else in
this thread but am still to commit) as this is much more configurable.

To turn it on you'd do something like

zstyle ':completion:*' completer _expand _complete _ignored
bindkey '^i' complete-word

but there are many more exotic possibilities.

I'll have a look at expand-or-complete word, too.

(Ideally, in fact, whether or not we expand ~[whatever] needs
configuring --- because this is dynamic completion you might decide to
expand it to freeze the path for future use.  I'll look at that if I get
the chance.  This is the sort of reason for using the expand completer
I'm talking about.)

This plus the small patch you sent earlier for _expand works, thanks!
I feel like expand-or-complete should work too, but as long as the
_expand patch makes it into the final code I'm happy.

Thanks again,

I've pushed that as is.  Whether or not tilde forms are expanded are
already configurable --- setting the accept-exact style in the
completer's context would control this.

(Off topic, but I'm not 100% convinced that the REC_EXACT shell option
should have that effect in this completer, as it currently does, since
it's a rather gross and uncontrllable setting that wasn't really
intended for expansion.  But I think all its uses are usurped by the
accept-exact style in the completion system anyway, so probably no big
deal.)

Yes, me too, particularly now Mikael has pointed out ^X*: I'll look
at this separately.

I think this works.

What was happening was as a last search for something to expand the code
looked wildcards, and the square brackets triggered that.

In this type of situation I usually explicitly press expand-word (^X*
by default I believe).

Yep, ideally as far as the internal and therefore non-configurable
widgets are concerned, I think we want expand-word to expand this and
expand-or-complete not to.  That's what happens with normal ~, so this
should be doable.
