cdr completion

cdr completion

[Yuri D'Elia]

With:

autoload -Uz chpwd_recent_dirs cdr add-zsh-hook
add-zsh-hook chpwd chpwd_recent_dirs
zstyle ':chpwd:*' recent-dirs-default true
zstyle ':completion:*' recent-dirs-insert always

the command:

cdr ~<TAB>

will still try to complete usernames (for the ~user home directory
completion), which is something I'd like to avoid.

Is this avoidable?

Hmm... I think you can turn it off generally with something like

zstyle ':completion::complete:-tilde-::' tag-order named-directories

(allow named directories but not usernames), but so far as I know
there's no way of doing it just after cdr.  The problem is the context
here is a special one, "-tilde-", which replaces the normal command
context, so it no longer cares.  This happens early enough that none of
the special code to do with cdr is ever run.

I don't think it's that difficult to rejig the context in _tilde, which
isn't a particularly big function, so that it does care, by extracting
$words[1] from the command line and sticking it appropriately in the
context.  For example, replace the -tilde- with -tilde-$words[1].  I
haven't tried this --- and although it's useful it will break
compatibility with anyone trying to do this sort of thing for all
commands, so you might be better off just experimenting locally.

This would be fine for me. The ~username expansion is something I never
ever used.

However the above style doesn't really disable the expansion for me.

Sorry, try:

zstyle ':completion::complete:-tilde-::' tag-order - named-directories

or perhaps better

zstyle ':completion::complete:-tilde-::' tag-order - \
  'named-directories directory-stack'

instead.  For some reason the other form was working for me, so I failed
to go and read the documentation, which is lethal.  The "-" is needed
to tell it that you *only* want the tags you specify completed.

Ah yes, thanks for pointing that out. Now it works as planned.
And, for maximum comfort:

zstyle ':completion::complete:-tilde-::' tag-order - \
  'named-directories:-home named-directories directory-stack'
zstyle ':completion::complete:-tilde-:*:named-directories-home' fake '/'

will complete ~ to ~/ if there is nothing else.

mmmh.

zstyle ':completion:*:-tilde-:*' users ''
