Convert path string to list of all paths

[William McKenzie]

Is there any simple expression/filter magic that would allow me to convert a path string to a list of all the contained paths.

So:

"a/b/c/d"

would become:

[ "a",  "a/b" , "a/b/c" , "a/b/c/d" ]

- hosts: localhost
connection: local
gather_facts: no
vars:
p: /usr/local/bin/opt/etc/opt/var/tmp/sbin/lib/blah/something/else
tasks:
- set_fact:
parts: "{{ p.split('/')|difference(['']) }}"
- set_fact:
all: "{{ all | default([]) | union([parts[0:idx+1]|join('/')]) }}"
loop: "{{ parts }}"
loop_control:
index_var: idx
- debug: var=all


Output:
