zsh alias expansion

Is it possible to configure zsh to expand global aliases during tab completion? For example, I have the common aliases:

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

but when I type, for example, cd .../some<tab> it won't expand to cd .../something or cd ../../something. Consequently, I frequently won't use these handy aliases because they are incompatible with tab completion.

Solution

  • I'm a user of Mikael Magnusson's rationalise-dot. From my zshrc:

    # This was written entirely by Mikael Magnusson (Mikachu)
# Basically type '...' to get '../..' with successive .'s adding /..
function rationalise-dot {
    local MATCH # keep the regex match from leaking to the environment
    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
