Zsh – alias -s with parameter

aliaszsh

In zsh, I can specify default program to open which file extension like alias -s {mkv,mpg}='mplayer' . I runs fine but what I really want is to run mplayer <filename> & so it won't produce technical stuffs and 'stealing' my current shell session.

How can I make this happen ?

Thanks for reading 🙂

You either provide a wrapper script or a function doing what you need, e.g:

background() {
  "$@" &
}

and use the function/script instead:

alias -s {mkv,mpg}='background mplayer'

Zsh alias expansion

Try looking up zsh abbreviations. They allow you to enter an "abbreviation" which automatically gets replaced with its full form when you hit a magic key such as space. So you can create one which changes ...<SPACE> to ../...

For example, this is what you need in your profile:

typeset -A abbrevs
abbrevs=(
        "..." "../.."
        "...." "../../.."        
)

#create aliases for the abbrevs too
for abbr in ${(k)abbrevs}; do
   alias -g $abbr="${abbrevs[$abbr]}"
done

my-expand-abbrev() {
    local MATCH
    LBUFFER=${LBUFFER%%(#m)[_a-zA-Z0-9]#}
    LBUFFER+=${abbrevs[$MATCH]:-$MATCH}
    zle self-insert
}

zle -N my-expand-abbrev    
bindkey " " my-expand-abbrev 
bindkey -M isearch " " self-insert

According to the Zsh Workshop Aliases they seem to have the same syntax, so they should work.
