v1.1.7 – new 0="…" snippet

[psprint]

Description

When working with Zsh scripting in past years I've developed a better 0="…" snippet that the older, 2-line one. It works everywhere, be it a sourced script, hash-bang binary script or autoloaded function. is 1-line and is essentially better than the old one, which was difficult to understand because of $ZSH_ARGZERO reference.

Motivation and Context

When one wants to get path to autoload function in order to get path to some share/… dir contents, he can:

my-function() {
    0=${${ZERO:-${(%):-%x}}:A}
    ls $0:h/share
}

How Has This Been Tested?

I've been using it in my projects: angel, tigsuite. zsh-sweep and others for about half of the year.
