So far I have written this code...
(defun org-capture-expand-headline (headline)
"Expand functions, symbols and strings for HEADLINE.
When HEADLINE is a function, call it. When it is a form, evaluate
it. When it is a variable, return its value. When it is a string,
treat it as a headline title. When it is `t', select existing headline
title or enter a new one. In any other case, raise an error."
(let* ((headlines (org-map-entries (lambda ()
(org-element-property :title
(org-element-at-point)))))
(final-headline (cond ((stringp headline) headline)
((functionp headline) (funcall headline
headlines))
((eq headline t) (completing-read "Enter
headline: " headlines nil 'confirm))
((and (symbolp headline) (boundp headline))
(symbol-value headline))
(t nil))))
(or (org-string-nw-p final-headline)
(error "Invalid headline: %S" headline))))
and I updated `org-capture-set-target-location' to use that function when
handling with target `file+headline'
What I am concerned about is the amount of tests I might have to write or
update for `org-capture'.
testing/lisp/test-org-capture.el
125: `(("t" "Todo" entry (file+headline ,file "A") "** H1 %?"))))
144: `(("t" "Todo" entry (file+headline ,file2 "A")
175: `(("t" "Todo" entry (file+headline ,file "A") "** H1 %?"))))
221: `(("t" "Todo" entry (file+headline ,file "A") "** H1 %?"))))
233: `(("t" "Test" entry (file+headline ,file "A") "** H\nFoo"
243: `(("t" "Test" entry (file+headline ,file "A") "** "
279: `(("t" "Item" item (file+headline ,file "A") "- X"))))
312: `(("t" "Item" item (file+headline ,file "A") "- X"))))
323: `(("t" "Item" item (file+headline ,file "A") "- X"
337: `(("t" "Item" item (file+headline ,file "A") "- X"
358: `(("t" "Item" item (file+headline ,file "A") "- X"
371: `(("t" "Item" item (file+headline ,file "A") "- X"))))
538: `(("t" "Table" table-line (file+headline ,file "Inbox")
552: `(("t" "Table" table-line (file+headline ,file "Inbox")
723: `(("t" "Text" plain (file+headline ,file "A") "Foo"
733: `(("t" "Text" plain (file+headline ,file "A") "Foo"
How do you think it should be tested if the headline can be 4 different
types?
Apology in advance if the formatting is off.
