Re: make aliases work inside the function? (using a preprocessor?)



In addition to what PWS and Oliver have said, it's possibly important
to point out that --

-- aliases are never going to expand with the command word quoted as
in your  "$@" substitution there.  Oliver's suggestion would work, but
only because (as he mentioned) the alias would be expanded on the
interactive command line before the € function runs.

For this specific example, what you want is probably:

€ () {
   setopt localoptions unset nowarncreateglobal
   eval "$1" "${(q@)argv[2,-1]}"
}

The eval will expand aliases in $1 (the desired command word)
regardless of the order in which they are defined relative to the
function, and the (q@) assures that the rest of the arguments are
unmolested by eval.

Other uses of aliases need the approach outlined by Peter.
