Add a decorator function to org-capture-template

Question

I wrote a org-capture-templates which add entries to appropriate headings as:

** Plan
** Writing

The org-capture-templates as:

(setq org-capture-templates
      '(("p" "Plan" entry
         (file+function "~/Documents/OrgMode/ORG/Master/todo.today.org"
                        (my-org-goto-last-headline "\\*\\* Plan"))
         "* TODO %i%?")
        ("w" "Writing" entry
         (file+function "~/Documents/OrgMode/ORG/Master/todo.today.org"
                        (my-org-goto-last-headline "\\*\\* Writing"))
         "* %i%? \n%T")))

my-org-goto-last-headline was defined as a decorator:

(defun my-org-goto-last-headline (heading)
  (defun nested ()
    "Move point to the last headline in file matching \"** Headline\"."
    (end-of-buffer)
    (re-search-backward heading))
  `nested)

Additionally, I set lexical-binding: t

Unfortunately, it report errors like:

org-capture-set-target-location: Invalid function: (my-org-goto-last-headline "\\*\\* Plan")

How could I apply a decorator in such a org-capture-template?

The function format should be (file+function "filename" function-finding-location).

You are not providing a function itself. You are giving it a list (function argument). Since it is not being executed you have that error.

You could write it in backquote and evaluate the function that returns the function object.

(setq org-capture-templates
      `(("p" "Plan" entry
         (file+function "~/Documents/OrgMode/ORG/Master/todo.today.org"
                        ,(my-org-goto-last-headline "\\*\\* Plan"))
         "* TODO %i%?")
        ("w" "Writing" entry
         (file+function "~/Documents/OrgMode/ORG/Master/todo.today.org"
                        ,(my-org-goto-last-headline "\\*\\* Writing"))
         "* %i%? \n%T")))

You will also need to quote the return nested in my-org- function.

Is it backquote ` or comma , ? – AbstProcDo Jan 06 '22 at 00:35
@AbstProcDo: yes – rajashekar Jan 06 '22 at 16:02
@rajashekar what do you mean by "yes"? which one is it: comma or backtick? – Artem Pelenitsyn Jan 16 '22 at 04:07
@AbstProcDo could you, please, accept the answer if it satisfies you? – Artem Pelenitsyn Jan 16 '22 at 04:08
@AbstProcDo: comma goes before an expression within a backquoted expression. https://stackoverflow.com/questions/30150186/what-does-backtick-mean-in-lisp – rajashekar Jan 19 '22 at 15:38
