Question / Feature request: Exclude fields in lists

[Kumm-Kai]

I'm not sure if this is already possible, I at least wasn't able to get it working.

from:

test:
- name: a
  version_min: 1.2.3
  version_used: 1.2.3
- name: b
  version_min: 1.2.3  
  version_used: 1.2.3

to:

test:
- name: a
  version_min: 1.3.0
- name: b
  version_min: 1.4.0

current diff:

❯ dyff between -b from.yaml to.yaml

test.a
  - one map entry removed:
    version_used: 1.2.3

test.a.version_min
  ± value change
    - 1.2.3
    + 1.3.0

test.b
  - one map entry removed:
    version_used: 1.2.3

test.b.version_min
  ± value change
    - 1.2.3
    + 1.4.0

expected diff (without the version_used field changes):

test.a.version_min
  ± value change
    - 1.2.3
    + 1.3.0

test.b.version_min
  ± value change
    - 1.2.3
    + 1.4.0

What I tried:

dyff between --exclude "version_used" from.yaml to.yaml
dyff between --exclude "*version_used*" from.yaml to.yaml
dyff between --exclude "/test//version_used" from.yaml to.yaml
dyff between --exclude "/test/*/version_used" from.yaml to.yaml
dyff between --exclude "/test/*/version_used" from.yaml to.yaml
dyff between --exclude ".test.[].version_used" from.yaml to.yaml
dyff between --exclude ".test.[0].version_used" from.yaml to.yaml # even tried explicitly provide an index
dyff between --exclude ".test.[*].version_used" from.yaml to.yaml
dyff between --exclude-regexp '.*version_used$' from.yaml to.yaml
dyff between --exclude-regexp '.*version_used.*' from.yaml to.yaml

You can try version from my PR #526

✗ ./dyff between --exclude-regexp ".*version_used.*" from.yaml to.yaml  
     _        __  __
   _| |_   _ / _|/ _|  between from.yaml
 / _' | | | | |_| |_       and to.yaml
| (_| | |_| |  _|  _|
 \__,_|\__, |_| |_|   returned two differences
        |___/

test.a.version_min
  ± value change
    - 1.2.3
    + 1.3.0

test.b.version_min
  ± value change
    - 1.2.3
    + 1.4.0

Awesome! This works like a charm 🤩

So it isn't because of lists in general but because it just didn't affect additions and removals, just changes.
