Completion on dots

Completion on dots

[Jesper Nygårds]

I have the following in my .zshrc:

alias -g ...='../../'

which of course allows me to write for example "ls ..." to show all
files in the grand-parent directory.

However, it doesn't work with completion: I can't write "ls
.../<TAB>", and have zsh complete on the available files in the
grand-parent directory.

Would it be possible to write such a completion function? And ideally,
for even more dot patterns: "...", "...." etc, to continue up in the
file hierachy?

Try this:

     setopt complete_aliases

Unfortunately I cannot answer your question, but there was a really neat funtion posted some month ago: http://www.zsh.org/mla/users/2010/msg00770.html

Perhaps that's an alternative for you, too!

.../ isn't an alias, so it won't work. ls .../foo will also not work,
regardless of completion. This is a better solution,

# just type '...' to get '../..', then additional . adds more /.. segments
_rationalise-dot() {
  local MATCH
  if [[ $LBUFFER =~ '(^|/| |	|'$'\n''|\||;|&)\.\.$' ]]; then
    LBUFFER+=/
    zle self-insert
    zle self-insert
  else
    zle self-insert
  fi
}
zle -N _rationalise-dot
bindkey . _rationalise-dot
# without this, typing a . aborts incremental history search
bindkey -M isearch . self-insert
