How to wrap a multiple options string in zsh

Slight variation based on assumption there aren't any other commands or variable assignments in the current rsync_basic_options.sh file:

$ cat rsync_basic_options
-aHSv
--progress
--force
--append-verify

There are then a few options for loading these into an array; a couple that come to mind:

$ ro=( $(< rsync_basic_options) )       # might be problematic if dealing with embedded white space

# or

$ mapfile -t ro < rsync_basic_options

Both of these populate the ro[] array with the following:

$ typeset -p ro
declare -a ro=([0]="-aHSv" [1]="--progress" [2]="--force" [3]="--append-verify")

Which can then be used in the script like such:

rsync "${ro[@]}" "$source/" "$target/"
