Hello, it's me again,
I figured out, what was wrong with the original code. I had gotten the
parentheses of the lambda wrong, which messed all this up.
I modified the code and refactored the lambda out into a proper
function, as you can see below:
----------------------------------------------------------------
(defun dl-org-refile-targets ()
(unless (member (buffer-file-name) org-agenda-files)
(buffer-file-name)))
(setq org-refile-targets
(quote ((org-agenda-files :maxlevel . 4)
(dl-org-refile-targets :regexp . ".*"))))
----------------------------------------------------------------
This does not throw any error anymore. I have, however, come upon
another problem that manifests itself when calling org-refile with the
cursor upon a heading in a file that is not a member of
org-agenda-files: I see "Getting targets..." in the modeline, which
takes a long time (I canceled it after ~2 minutes).
What exactly does :regexp . ".*" do? I thought it would simply take
_all_ headlines in the file indicated by dl-org-refile-targets. The
file I testet this with has less than 100 headlines and I have no
idea why this takes so long.
After changing the contraint to :maxlevel 4 as you can the below, it
works just fine. (Note: The file in question has only headlines with
levels <= 2)
----------------------------------------------------------------
#+begin_src emacs-lisp
(defun dl-org-refile-targets ()
(unless (member (buffer-file-name) org-agenda-files)
(buffer-file-name)))
(setq org-refile-targets
(quote ((org-agenda-files :maxlevel . 4)
(dl-org-refile-targets :maxlevel . 4))))
----------------------------------------------------------------
What did I miss here? Any help is appreciated.
Regards,
Alex
