Rather than adding a new filter, I think we can take advantage of the existing post-selector.

apiVersion: argoproj.io/v1alpha1
kind: ApplicationSet
metadata:
  name: guestbook
spec:
  goTemplate: true
  generators:
  - pullRequest:
      github:
        owner: myorg
        repo: myrepository
    values:
      titleMatches: '{{ regexMatch "some-regex" .title }}'
    selector:
      matchLabels:
        values.titleMatches: "true"

I haven't tested this, but seems like it should work. We'd still need to add the title parameter, but we'd avoid the new filter field.

Indeed, that could be a solution as well. I will try it out locally later and see how it goes

I don't see the values bloc in the doc neither in the ApplicationSet spec...

Ah, we need to add that values field to all generators. Try this.

kind: ApplicationSet
metadata:
  name: guestbook
spec:
  goTemplate: true
  generators:
  - matrix:
      generators:
      - pullRequest:
          github:
            owner: myorg
            repo: myrepository
      - list:
          elements:
          - titleMatches: '{{ regexMatch "some-regex" .title }}'
    selector:
      matchLabels:
       titleMatches: "true"

Just tested, and that actually works.

It seem that the title key is currently not available on argocd 2.10.1

A PR adding the title parameter is ready for review #17907
