Completion does not work with hidden files/directories

Completion does not work with hidden files/directories

Hello gurus of ZSH,


In my home directory, there are currently only hidden files/directories and
the completion mechanism does not see them  :-(

Few examples...

user@hostname [12:07:01]:~ % ls
No matches for: `files'

But if I manualy insert a dot :

user@hostname [12:27:06]:~ % ls .
--==[ files ]==--
.Maildir/   .Xdefaults  .cache/     .config/    .cshrc      .cvsrc
 .local/     .login      .mailrc     .nanorc     .profile    .ssh/
.zsh/


Same issue when I want to change of directory :

user@hostname [12:28:30]:~ % cd
No matches for: `local directory'

user@hostname [12:29:31]:~ % cd .
--==[ local directory ]==--
.Maildir/  .cache/    .config/   .local/    .ssh/      .zsh/


The completion does work fine with not hidden files/directories.
What is wrong with my file "~/.zsh/completion" ?

Note : my machine runs OpenBSD v5.9 with zsh v5.8 ; I do not know if it
matters.

Second issue (less important) : the section "Create a cache" in the above
file does not work.

The main way to control which files are included in file completion is
via the file-patterns style. So if you always want to see hidden files,
it would be something like:

  zstyle ':completion:*' file-patterns '%p(D):globbed-files *(D-/):directories' '*(D):all-files'

(D) is a glob qualifier that includes hidden files and you might use it
from the command-line as, e.g. *.png(D)

I was going to suggest something like the following which adds the (D)
to the all-files fallback:

  zstyle ':completion:*' file-patterns '%p:globbed-files *(-/):directories' '*(D):all-files'

Unfortunately, _files has some sort of shortcut where it does:

  [[ "$pat" = '*' ]] && return ret

So it never tried all-files if globbed-files was using * as a glob. This
should perhaps be looked into and discussed on -workers.

What you can do, however is add a second run of the _complete completer
with the separate file-patterns style:

  zstyle ':completion:*::::' completer _complete _complete:-hidden
  zstyle ':completion:*:complete-hidden:*' file-patterns '%p(D):globbed-files' '*(D):all-files'

Note, however that you likely already have a completer style with other
functions like _expand listed and you should only add _complete:-hidden
to the list somewhere after _complete.

cd doesn't use files so file-patterns may not help there.

Only some completion functions need to create a cache. Note that those
lines do not create a cache, they only tell completion where to put cache
files. Is ${ZDOTDIR} definitely set to something. If not, it could be
trying /zsh_cache. The directory you specify should already exist and should be a writable directory.
