Why is there no "break" support for flow control methods in helm template

Question

I have a range function but would like to break from the control if certain condition is met. Is there a way this can be achieved in helm template

UPDATE:

I have seen some related queries where conclusion is "break" is unsupported. But would like to get some official documentation OR reason in case this is not supported.

Answer 1

Have some good news here! Not sure from which exact version of helm the update happened but you can for sure use the break in your templates with the newest [email protected].

This is because the new version of helm bumped the go version to 1.20 and the break has been introduced in the text/template in go v1.18.

So now you can do stuff like this:

  {{- range $i, $e := until 10 -}}
    {{- if lt $i 5 -}}
      Less than five.
    {{- else -}}
      {{- break -}}
    {{- end -}}
  {{- end -}}

Happy helming!
