Currently i have around 25 org files each with multiple headings. Everytime i want to go over my notes, i need to remember the name of the file and open it (faster if its in buffer, else i need to go to the org folder)
Is there a way to generate a TOC of files/heading1 for all files under the org-directory and place it under an index.org?
P.S: Google did not return any good package!
There are a couple of options. I would not create a permanent index.org file, because it would take some extra effort to keep it up to to date. If you don't mind installing f.el and helm, here is a dynamic way to get a list of all the headings.
(defun org-toc () "Generate a table of contents for org-files in this directory." (interactive) (let ((org-agenda-files (f-entries "." (lambda (f) (f-ext? f "org")) t))) (helm-org-agenda-files-headings))) If you really want a buffer with headlines, you could try this approach to make a temporary buffer with links to the headlines:
(defun org-toc () (interactive) (let ((headings (delq nil (loop for f in (f-entries "." (lambda (f) (f-ext? f "org")) t) append (with-current-buffer (find-file-noselect f) (org-map-entries (lambda () (when (> 2 (car (org-heading-components))) (cons f (nth 4 (org-heading-components))))))))))) (switch-to-buffer (get-buffer-create "*toc*")) (erase-buffer) (org-mode) (loop for (file . heading) in headings do (insert (format "* [[%s::*%s]]\n" file heading))))) Here is another approach I have used:
(defun org-toc () (interactive) (let ((files (f-entries "." (lambda (f) (f-ext? f "org")) t)) (headlines '()) choice) (loop for file in files do (with-temp-buffer (insert-file-contents file) (goto-char (point-min)) (while (re-search-forward org-heading-regexp nil t) (cl-pushnew (list (format "%-80s (%s)" (match-string 0) (file-name-nondirectory file)) :file file :position (match-beginning 0)) headlines)))) (setq choice (completing-read "Headline: " (reverse headlines))) (find-file (plist-get (cdr (assoc choice headlines)) :file)) (goto-char (plist-get (cdr (assoc choice headlines)) :position)))) if you have helm or ivy setup to do completion, it should use them to help pick the headlines. This takes about 4-5 seconds for me on about 3500 headlines.
