Note that to enable displaying labels in 'list' output, you need to append to queryfields:

queryfields: "summary,created,updated,priority,status,reporter,assignee,labels"

Looks good. An alternative to using join would be something like this:

labels: {{ range .fields.labels }}
  - {{ . }}{{end}}

and just iterate over the labels and print them out, one per line.

Oh, I see, you wanted this for "list", I was thinking "view", so you obviously don't want to print multiline stuff in "list". So ignore my comment :)

Thanks,

Uh, how do I use this? I tried to do the following:

  - name: search
    help: search for text
    script: echo jira list --query='text ~ \"{{ join " " args.ARGS }}\"'
    args:
      - name: ARGS
        repeat: true

But got: ERROR Invalid Usage: template: gojira:1:45: executing "gojira" at <args>: wrong type for value; expected []interface {}; got []string
