Example: Pass array to bash function with command substitution #bash #bash_exemplar

Exemplar_pass_array_to_bash_function_with_command_substitution

Context:
Pass array to function, where one or more elements of the array have embedded spaces.
  Moreover, script seeks a nonnumeric result from function; uses command substitution to call the function.
  For the case without command substitution, see https://gist.github.com/jimratliff/ddcb5eb7e6fb184840e5dfd7e240c7ee
Goal: Have the embedded spaces respected in the array processed by the function.
############### The script
#!/usr/bin/env bash
set -eu
function echo_passed_array() {
	list_of_options=("$@")
	echo "List of options [0]: ${list_of_options[0]}"  > /dev/tty
	echo "List of options [1]: ${list_of_options[1]}"  > /dev/tty
	echo "List of options [2]: ${list_of_options[2]}"  > /dev/tty
	echo "${list_of_options[1]}"
	return 0
}
# Main
two_word_element="Maybe someday"
declare -a available_options
available_options[0]="Yes"
available_options[1]="No"
available_options[2]="$two_word_element"
result_of_function="$(echo_passed_array "${available_options[@]}")"
echo "Result of function is: $result_of_function"
############### The output
List of options [0]: Yes
List of options [1]: No
List of options [2]: Maybe someday
Result of function is: No
