Re: autoload variables

hello zsh users,

> We can autoload functions but is there a way to autoload variables?

i was hoping for a better answer than mine (reading this list provides
me so many "wow" moments). the way i dealt years ago to deal with my
"too heavy .zshenv" is to write what i call "modules"

<<\. cat > /usr/local/bin/mynetstuff.zsh
# yes i use setopt pathdirs :)

export IFUP=$( ip -4 r |sed ...)

mynetstuff/thing () { ... }
mynetstuff/stuff () { ... }
.

now i can run

. mynetstuff.zsh

when i need my net stuff.  to unload functions, you can write

    unset 'functions['$^functions[(I)mynetstuff/*]']'

oth.

besides: if the sed command is for real, i'm curious about
how it works:

    sed -n -e '/^default/ s/^default.*dev //; s/ > .*// p;q'

my guess is it is equivalent to

    sed -r '/^default dev (\S+) .*/!d; s//\1/; q'

or

    ip -4 r | sed -r '/^default dev /!d; s///; s/ .*//; q'

but as you quit anyway, i assume you *know* that what you need is on the
first line so this should do the job:

    ip -4 r | head -n1 | cut -d' ' -f3
