--parser yaml

Input:

apiVersion: v1
kind: Service
metadata:
  name: my-service
spec:
  ports:
  - protocol: TCP
    port: 10000
    targetPort: 20000
  - protocol: TCP
    port: 10001
    targetPort: 20001
  - protocol: TCP
    port: 10002
    targetPort: 20002
  - protocol: TCP
    port: 10003
    targetPort: 20003
  - protocol: TCP
    port: 10004
    targetPort: 20004
  - protocol: TCP
    port: 10005
    targetPort: 20005
  - protocol: TCP
    port: 10006
    targetPort: 20006

Output:

apiVersion: v1
kind: Service
metadata:
  name: my-service
spec:
  ports:
    - protocol: TCP
      port: 10000
      targetPort: 20000
    - protocol: TCP
      port: 10001
      targetPort: 20001
    - protocol: TCP
      port: 10002
      targetPort: 20002
    - protocol: TCP
      port: 10003
      targetPort: 20003
    - protocol: TCP
      port: 10004
      targetPort: 20004
    - protocol: TCP
      port: 10005
      targetPort: 20005
    - protocol: TCP
      port: 10006
      targetPort: 20006

Expected output:

apiVersion: v1
kind: Service
metadata:
  name: my-service
spec:
  ports:
  - {protocol: TCP, port: 10000, targetPort: 20000}
  - {protocol: TCP, port: 10001, targetPort: 20001}
  - {protocol: TCP, port: 10002, targetPort: 20002}
  - {protocol: TCP, port: 10003, targetPort: 20003}
  - {protocol: TCP, port: 10004, targetPort: 20004}
  - {protocol: TCP, port: 10005, targetPort: 20005}
  - {protocol: TCP, port: 10006, targetPort: 20006}

Why?
In sequences, similar structures are often repeated.
When there are sufficiently few keys for the elements, a compact flow-style format on a single line can reduce the amount of scrolling, making it easier to compare elements and potentially improving visibility.

Start by reproducing the YAML example with the linked Playground configuration and the yaml parser. Trace the formatter's YAML sequence handling from the parser entry point, then add coverage for the shown input and expected flow-style output. Done means the repeated short mappings format compactly without changing unrelated YAML output.
