cd ..<tab>?

cd ..<tab>?

[Bo Thorsen]

Hi all,

I'm just giving zsh yet another try, but my biggest beef with it is still 
there:

> cd ..<tab>

doesn't expand to ../ which is quite annoying on a danish keyboard. Tab is 
easily hit but / is shift+7. Small issue, but when something's annoying, it 
only grows worse.

I have searched the web and the manual without finding this. I expect there 
is some way of setting up completion to this, but I haven't figured it out 
yet.

Could some zsh guru please show me how to do this? And cc me since I'm not on 
the list.

Thanks a lot.

Bo.

I assume you're using the new completion system, i.e., you call

  autoload -U compinit
  compinit

in any of the init files.

Then you can just do:

  zstyle ':completion:*' special-dirs ..

to make `..' be considered a possible match (and hence it will get the
slash appended).


Bye

Is there a way to make this work properly with setopt GLOB_DOTS?
Such that .. is not tabcompleted once you have already entered a directory?

Just make the style more specific:

  zstyle ':completion:*:(cd|chdir|pushd|popd):*' special-dirs ..

You might also check the documentation for the ignore-parents style.

ignore-parent works the wrong way...

It want to ignore '..' when it is a stupid choice.
eg.
mkdir Z
cd Z/[tab]
should NOT complete to 'cd Z/../'
(unless CHASE_DOTS is on and 'cd Z/..' will be different from 'cd .')

likewise...
mkdir Z
mkdir Z/Y
cd Z/[tab]
should NOT give me '..' as a choice, but just complete to 'cd Z/Y'
(unless CHASE_DOTS is on and 'cd Z/..' will be different from 'cd .')

Apparently I misunderstood the question.  It'll help by making ".." not
be completed for commands other than "cd" et al., which was the only
way I could think of (at the time) that GLOB_DOTS could be involved.

Aha.

} It want to ignore '..' when it is a stupid choice.
} eg.
} mkdir Z
} cd Z/[tab]
} should NOT complete to 'cd Z/../'
} (unless CHASE_DOTS is on and 'cd Z/..' will be different from 'cd .')

This is a case where you need 'zstyle -e'.  You want the special-dirs
style to be non-empty only in certain circumstances.

This completes `..' only if the prefix is either empty, or has a leading
`.' and contains no slashes:

    zstyle -e ':completion:*' special-dirs \
        '[[ $PREFIX = (|.[^/]#) ]] && reply=(..)'

To find out that `Z/..' is not the same directory as `.' requires a bit
of extra work, which I don't have time to do just now, but you can see
how you'd just insert that into the conditions under which the reply
array is set by the style.

heh Thanks. I didnt know I could run a "script" here :)

zstyle -e ':completion:*' special-dirs \
   '[[ $PREFIX = (../)#(|.|..) ]] && reply=(..)'

This will continue to work with cd ../../../..[tab] while working with 
cd .[tab]

Would you please add your (or my) little script to the documentation 
under special-dirs? :)
