I'd like to understand how to retrieve the tags for a headline that is being processed by a clock mode report formula. Suppose I have a clock report table defined like this.
#+BEGIN: clocktable :maxlevel 2 :scope nil :formula "$3='(headline-get-tags $1)::@2$3=string(\"Tags\")" #+END:
I can define a simple formula that returns the length of the headline, but I have yet to find an easy way to find the tags associated with the headline.
(defun headline-get-tags (headline) "Return the tags for a headline" (length headline))
Is there a simple way to get the tags with a headline?
