How to create unnamed temporary arrays?

How to create unnamed temporary arrays?

[Hannu Koivisto]

Greetings,

I'm currently using something like this to list the base names of
files in /usr/local/etc/packages/ directory, each name on its own
line:

echo ${(F)$(echo /usr/local/etc/packages/*(.:t:r))}

This has the obvious problem that it doesn't work if filenames have
spaces in them.  I just couldn't figure out any way to do something
corresponding to:

kala=(/usr/local/etc/packages/*(.:t:r))
echo ${(F)kala}

without creating that temporary array variable.  Not that this
really matters in this case, but I've faced situations earlier
where avoiding the temporary name might have been more convenient
and now I finally have a simple enough example to demonstrate it.

So, is there a way?  I'm using zsh versions 3.1.9-dev-6 and
3.1.9-dev-8 from Debian GNU/Linux testing/unstable and stable,
respectively.

If I got that right and you really only want those filenames one per
line, you can just use:

  print -l /usr/local/etc/packages/*(.:t:r)

(the -l option to print makes it print the argument one per line).

Not quite; that package listing job was just a simple example using
which I was able to demonstrate the kind of situations in which I
might want to create unnamed temporary arrays.  I.e. I'd really like
to know if it is possible to rewrite this...

kala=(/usr/local/etc/packages/*(.:t:r))
echo ${(F)kala}

...so that kala variable is not defined but the ${(F)...}
construction is still used.

|   print -l /usr/local/etc/packages/*(.:t:r)

Thanks for the tip, though.

The idea I had today (in relation to other things) was to introduce new
syntax, something like

${foo-(bar baz)}

(note braces). Combined with empty parameter name (it is legal) it makes
it possible to do

${(F)${:-(foo bar baz)}}

thus giving you exactly what you want.

I do not claim that I fully understand the parameter substitution code,
but it looks doable. There remain some decisions to make though.

There was a discussion of exactly this subject on zsh-users in December.
Start with

    http://www.zsh.org/mla/users/2000/msg00728.html

(The canonical way to access that should be
    http://www.zsh.org/cgi-bin/mla/redirect?USERNUMBER=3560
but the redirector doesn't seem to be working right now.)

You mean the parens?

The problem with that is that it's semantically incompatible with syntax
that is parseable by standard sh, in which the parens would not have any
special meaning in that expression.  (Zsh's other overloadings of parens
have been to introduce them where they'd actually cause a syntax error
in sh.)  The above would have to be combined with some other signifier,
such as a new parameter flag, or an option.

The real issue of course is that there's no way to do filename generation
within a parameter expansion without resorting to command substitution.
Even given a syntax for embedding an array construction within the ${...},
you can't accomplish what's being asked for in 3560 and 3630 unless you
can also force a glob.

So the best mechanism for creating an "anonymous array" is probably:

    "${(ps:\0:)$(print -nN ...)}"

where `...' is the glob expression or whatever, which of course can be
optimized depending on what you plan to do with the array.

Is it only for me that
   echo ${(F)$(echo /var/spool/news/de/comp/**/*(.:t:r))}
seems to work? Well, the problem may be spaces in the values, but even
that should be solveable...

Ciao,

Of course is works. Actually, it is the only way to get globbing inside
parameter substitution.

Stop _path_files from searching /

[Christoph Lange]

Hi,

  when I try to complete a path name like /path/to/dir in zsh 3.1.9 on
Linux, the completion function _path_files steps up the directory tree and
searches for completions in /, /path, /path/to and /path/to/dir. These
directories are not in my cdpath.

  This annoys me because my slow CD-ROM drive is automounted with autofs.
When a CD lies in the tray and a path is completed, zsh accesses /cdrom and
thereby mounts the CD-ROM. Of course, I could remove the symlink from /cdrom
to the autofs directory, but I'd rather like to get the job done by
configuring the zsh completion.

Any ideas?

Thanks in advance,

Christoph

What has it to do with cdpath? _path_files completes partial file path; it is
used by many other completion functions, _cd including.

I do not understand. _path_files basically evaluates

/path*/to*/dir*

so unless you try to complete something like

/cd/some/path/file

/cdrom will never be touched. Can you give specific example of what you try to
do? Together with zstyle -L output.
