I use org-roam-dailies for my TODO lists for given day. And currently, I set my org-agenda-files to org-roam-dailies's directory as below:

  (setq org-agenda-files  '("~/roamnotes/daily/"))

Problem: as my number of daily entries increasing, org-agenda is loading all my entries in the directory above, resulting quite some time lag.

Possible Fix: For me, I don't need to load entries that's older than 2 or more week, (and also 2 weeks in the future). Less files to open = faster org-agenda. Daily entries have filename format yyyy-mm-dd.org (e.g. 2022-11-09.org). So I'm guessing that with some regular-expression tricks this can be achieved.

Question: How to make org-agenda to load entries that is within ±2 weeks time windows?

Here's a function that you can use:

;;; -*- lexical-binding: t -*-

(defun my/filter-org-roam-dailies (dir ndays-before ndays-after)

  "Filter the list of files in DIR that have a `.org' suffix. They are all
 supposed to have names of the form \"YYYY-MM-DD.org\". We only
 accept those whose names have a date part that falls within the
 date range `<today> - NDAYS-BEFORE' and `<today> + NDAYS-AFTER',
 inclusive of the ends dates."

  ;; This "inner" function finds the "free" variables `ndays-before' and
  ;; `ndays-after' in the lexical environment, in this case the
  ;; arguments of the "outer" function
  (cl-flet ((my/pred-org-roam-dailies (filename)
    "Check if the FILENAME qualifies for inclusion."
    (let ((fname-date (file-name-sans-extension (file-name-nondirectory filename)))
          (date-min (format-time-string "%Y-%m-%d" (time-add nil (* -86400 (+ 1 ndays-before)))))
          (date-max (format-time-string "%Y-%m-%d" (time-add nil (* 86400 (+ 1 ndays-after))))))
      ;; if the date corresponding to the name of the file falls between date-min
      ;; and date-max, return the (complete) filename
      (when (and (string<  date-min fname-date) (string< fname-date date-max))
    ;; end of inner function

    ;; the "outer" function maps the above predicate on the list of files
    ;; with a ".org" suffix in the given DIRectory and returns the
    ;; filtered list (after deleting nil entries).
    (delq nil
          (mapcar #'my/pred-org-roam-dailies (directory-files dir t "\\.org\\'")))))

Save the above in a file, load the file and then you can use the function like this:

(setq org-agenda-files (my/filter-org-roam-dailies "~/roamnotes/daily/" 14 14)

Check the value of org-agenda-files afterwards (with C-h v org-agenda-files) to make sure you got everything you wanted.

You will have to recalculate org-agenda-files every day however: there is no automation for that in this answer.

EDIT: Fixed the regexp in the directory-files call to match only .org files. This is the same regexp as the one used in auto-mode-alist, so it should be correct, but it's only lightly tested at this point.

  • Thanks dude ! This Rocks

  • This seems accepting the emacs backup for each org-files. (both 2023-04-04.org & 2023-04-04.org~ loaded.) How to exclude files that are ends with ~?

    Fixed the regexp to do that. Thanks for the heads-up! I should have seen that coming :-)
