Pass annotation to ignore specific lines

[ImIOImI]

I would like you to expand the application selection/ignore syntax to include the ability to ignore specific yaml values. For example, I have a configmap with the following diff:

 apiVersion: v1
 data:
-  install_id: ee096b1b-7af3-4d55-b88e-ea75acbc66f1
-  install_time: "1735944438"
+  install_id: 0126b3ad-ab3e-4a51-8fe1-20de241b7383
+  install_time: "1735944478"
   install_type: k8s_manual
 kind: ConfigMap
 metadata:
   labels:
     app.kubernetes.io/instance: datadog-eks-cluster-name
     app.kubernetes.io/managed-by: Helm
     app.kubernetes.io/name: datadog
     app.kubernetes.io/version: "7"
     argocd.argoproj.io/instance: datadog-eks-cluster-name
     helm.sh/chart: <version>
 ---

install_id and install_time are pretty useless from a comparison point of view, and I'd like to be able to pass annotations or labels that told Argo Preview to ignore them.

Another example is the token generation for a datadog cluster agent:

 spec:
  revisionHistoryLimit: 10
  selector:
    matchLabels:
      app: datadog
  template:
    metadata:
      annotations:
        checksum/autoconf-config: <token>
        checksum/checksd-config: <token>
-        checksum/clusteragent_token: <token>
+        checksum/clusteragent_token: <token changed>
        checksum/confd-config: <token>
        checksum/install_info: <token>
        container.apparmor.security.beta.kubernetes.io/system-probe: unconfined
      labels:
        admission.datadoghq.com/enabled: "false"
        app: datadog
        app.kubernetes.io/component: agent
        app.kubernetes.io/instance: datadog-eks-cluster-name
        app.kubernetes.io/managed-by: Helm
        app.kubernetes.io/name: datadog

Hi @ImIOImI,

I understand your frustration! I had the same experience.
I believe you can run the tool with --diff-ignore="install_time|install_id", which will ignore all lines containing either of those two words. It uses regex to filter the lines: [docs].

Let me know if that solves your problem! :)

Did that help?
