If what you're really after is being able to dump the value of
$dirstack to a file to be able to restore it from that file later, you
could just use some trickery:
dump_dirstack() {
print -lr 'dirstack=(' "${(q@)dirstack}" ')' > ~/.dirstack
}
# pretty useless wrapper function...
restore_dirstack() {
. ~/.dirstack
}
Or some such.
A generic function to store an array (1st arg) to a file (2nd arg)
would be:
dump_array() {
print -lr "$1=(" "${(P@q)1}" ')' > $2
}
Hope that helps...
Bye
Sven
