I want to modify elfeed using this article: https://cundy.me/post/elfeed/

I cannot load the following code:

(defun concatenate-authors (authors-list) "Given AUTHORS-LIST, list of plists; return string of all authors concatenated." (mapconcat (lambda (author) (plist-get author :name)) authors-list ", ")) (defun my-search-print-fn (entry) "Print ENTRY to the buffer." (let* ((date (elfeed-search-format-date (elfeed-entry-date entry))) (title (or (elfeed-meta entry :title) (elfeed-entry-title entry) "")) (title-faces (elfeed-search--faces (elfeed-entry-tags entry))) (feed (elfeed-entry-feed entry)) (feed-title (when feed (or (elfeed-meta feed :title) (elfeed-feed-title feed)))) (entry-authors (concatenate-authors (elfeed-meta entry :authors))) (tags (mapcar #'symbol-name (elfeed-entry-tags entry))) (tags-str (mapconcat (lambda (s) (propertize s 'face 'elfeed-search-tag-face)) tags ",")) (title-width (- (window-width) 10 elfeed-search-trailing-width)) (title-column (elfeed-format-column title (elfeed-clamp elfeed-search-title-min-width title-width elfeed-search-title-max-width) :left)) (authors-width 50) (authors-column (elfeed-format-column entry-authors (elfeed-clamp elfeed-search-title-min-width authors-width 100) :left))) (insert (propertize date 'face 'elfeed-search-date-face) " ") (insert (propertize title-column 'face title-faces 'kbd-help title) " ") (insert (propertize authors-column 'face 'elfeed-search-date-face 'kbd-help entry-authors) " ") ;; (when feed-title ;; (insert (propertize entry-authors ;; 'face 'elfeed-search-feed-face) " ")) (when entry-authors (insert (propertize feed-title 'face 'elfeed-search-feed-face) " ")) ;; (when tags ;; (insert "(" tags-str ")")) )) (setq elfeed-search-print-entry-function #'my-search-print-fn)

I put this code in dotspacemacs/user-init and dotspacemacs/user-config and tested it separately... the code does not work.

However, when I reload my config (SPC f e R) the code loads just fine and my elfeed gets modified. But ONLY when I reload my config... it's not working after a normal restart or start up of emacs. What's wrong?

  • I am not sure what you mean. Of course, after placing code in dotspacemacs/user-config you should reload your dotfile using SPC f e R, or alternatively restart Spacemacs. Do you mean it did not work even after restarting Spacemacs? Commented May 6, 2023 at 9:33
  • Yes...sorry... the config does not load after restart. Only when I do SPC f e R Commented May 6, 2023 at 10:32
  • As loading works correctly after using SPC f e R, I guess your init file loads successfully, incl. the user-config and user-init sections. So I guess your elfeed-search-print-entry-function variable gets redefined when starting and (auto)loading elfeed. Please, after restarting Spacemacs, check the value of elfeed-search-print-entry-function before starting and after starting 'elfeed'. If they are different then wrap your setq form as follows (with-eval-after-load 'elfeed-search (setq elfeed-search-print-entry-function #'my-search-print-fn)). Commented May 6, 2023 at 11:50

    you are right! elfeed-search-print-entry-function is overwritten in the start up... by elfeed goodies! I guess, when I find out, how to get rid of this, everything should work out fine Commented May 8, 2023 at 16:53
  • The suggested with-eval-after-load does not work? Commented May 9, 2023 at 5:03
  • sadly no... elfeed-goodies somehow overwrites the functions Commented May 9, 2023 at 8:15
  • Ah okay, I wasn't aware the elfeed-goodies is actaully a package. So then try replacing 'elfeed-search with 'elfeed-goodies' in that with-eval-after-load. Commented May 9, 2023 at 8:47

    I have the feeling that the problem shifted from my original question. I will mark your answer as accepted and create a new question! Thank you very much! Commented May 17, 2023 at 14:30

Future-me here: I found that has to edit the elfeed layer to make the custom elfeed-search-print-entry-function work.

This layer can be found here: .emacs.d/layers/+readers/elfeed/

I looked in config.el and packages.el and deleted all functions and variables containing the word "goodies".
