na=\"nil\" in ob-R.elo
Probably a silly question, but in ob-R.el, what is the reason for setting na=\"nil\" when defining org-babel-R-write-object-command? Is this an elisp compatibility thing? Regardless, I generally (always?) want na=\"\" for this, so I am finding all those "nil"s very annoying, and the only way that I see to defeat them is to redefine org-babel-R-write-object-command. If there is no reason for the current behavior (doubtful I know) and if I am not missing an obvious work-around, then I would like to suggest changing this behavior. Otherwise, would it be feasible to add an option for R code blocks (:nastring?) where one could specify the NA replacement string? What do you think? It's easy to suggest I know and certainly beyond my elisp coding skills at present, but I am supposing that someone more fluent in elisp could do this safely without too much trouble.
bug#42484: 26.1: org-mode should display value of links in mini-buffer
by activate i mean display, in echo area, whatever it is i want to display. i think help-echo is a text property, and i might or might not want to display it, depending. and i might want to display the other stuff even if there is no help-echo. i use [and adore] org-link-minor mode in elisp mode. it highlights links and timestamps and makes links followable. i even use [[target]] <> within elisp buffers, and org id links that go from elisp to org and vice-versa. if org-link-minor-mode is active in an elisp buffer, i can run the following to detect whether cursor is over an org ts. (defun hoka-eldoc-at-point () (when (eq 'org-date (get-text-property (point) 'face)) (format "%s" (when (fboundp 'alpha-org-time-span) (with-no-warnings (alpha-org-time-span)) then i get the time span in the echo area. a time span is e.g. -1 for yesterday. it could just as well be a timestamp in a different format or lang. so that's great. but i want mouse hover to do the same thing, and to do so with a delay. and i want links of course. more generally, i might occasionally want /some/ eldoc type stuff and /some/ help-echo stuff. so org-link-minor-mode was useful in my case because it [i think it is it] adds face property which can be used. and i thought that might be useful to you. idk though. in my case i find it a bit overwhelming to get whatever solution i use for cursor to also work for mouse [with appropriate delays]. and get whatever else to work and to not have anything annoyingly display.

Ready to merge! Re: [PATCH] Enhance org-html--build-meta-info
This thread has dragged on ages, and if no-one else is following this chain I wouldn't blame them in the slightest. To help indicate that this is actually ready (at last) now, I'm just going to add that info the the subject line in the hope it helps Bastien or any others notice that this is actually good to go now :) -- Timothy Jens Lechtenboerger writes: > This looks fine to me.

Bug: Unexpected movement of cursor when commenting code blocks
Remember to cover the basics, that is, what you expected to happen and what in fact did happen. You don't know how to make a good report? See https://orgmode.org/manual/Feedback.html#Feedback Your bug report will be posted to the Org mailing list. When I am inside a code block like this: #+begin_src emacs-lisp (use-package org :defer :config (setq blahblah t)) ; cursor on this line #+end_src and I hit "C-x C-;" to comment the line, the cursor automatically jumps to the second line of the code block after the comment is made. I would expect the cursor to move forward one line like it usually does and this only happens in Org-mode, not when I edit the code block in a separate buffer with "C-c C-'". #+begin_src emacs-lisp (use-package org :defer ; cursor jumps to this line :config ;; (setq blahblah t)) #+end_src This happens no matter how big the code block is, and it always jumps to the second line of the code block. I was able to reproduce this with the "minimal-org.el" file. Emacs : GNU Emacs 28.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.23, cairo version 1.16.0) Package: Org mode version 9.4.4 (9.4.4-3-gbd1c31-elpaplus @ /nix/store/ybfrs7h4byc03f963flgc845n3m1dkhi-emacs-packages-deps/share/emacs/site-lisp/elpa/org-plus-contrib-20201228/)
[Patch] [Objective]Caml dialect in listings
Hi, I have just started using `org-mode`, and it is very cool ! Thank you for your collective work. There is a small patch I would like to submit : when writing listings for the OCaml programming language, one should use the "[Objective]Caml" dialect, which is different from the "Caml" dialect. This is not reflected in the latex exported code. The attached patch changes this. Thank you in advance for your patience, this is my first patch so I hope I did everything correctly.

Hah, I check and guess what I see? The changes were unstaged .
Sorry about that, here's an actual revision.

Subject: [PATCH 1/2] lisp/ox-html.el: make html meta tag builder nicer
* lisp/ox-html.el (org-html--build-meta-info): Multi-line repeated
structure extracted to new function `org-html--build-meta-entry'.
The keyword value formatting is changed from `org-export-data' to
`org-html-encode-plain-text' to avoid potentially nesting HTML tags in
meta tags and the element, which would violate W3C.

bug#42484: 26.1: org-mode should display value of links in mini-buffer
> this is an interesting discussion. is there any side discussion that > takes into account both mouse and cursor? Indeed, you can see a side discussion at https://lists.gnu.org/archive/html/emacs-devel/2020-11/msg00885.html where we discussed highlighting the completion candidate the same way whether the mouse pointer hovered over it, or the cursor moved to its buffer position. That discussion also mentions another way to display help-text using cursor-sensor-mode, i.e. after enabling it, cursor-sensor-functions can detect when the cursor enters the help-text property, then display it in the echo area. > 1] displaying value of link in echo area [the problem you are > discussing -- don't let me derail it] with a short nonzero delay > 2] doing so *for both cursor and mouse* -- too much futzing here > 3] also doing other stuff -- also futzing > > other stuff includes maybe [or maybe not] showing function signature > or docstrings in elisp buffers [possibly with longer delay], and > showing the time span in number of days from now to the org timestamp > at point or under mouse in any mode. This looks like the 5th possible way to implement this using eldoc, in addition to tooltips, post-command-hook, help-at-pt, cursor-sensor-mode. > i have code for the last thing. the problem is figuring out making > tooltips, eldoc, help-at-pt, or post-command-hook work with mouse > and keyboard without verbose help-echo like in dired. also the > major/minor modes and help-at-pt has an option to ignore verbose help-echo in dired. post-command-hook can be enabled locally only in org-mode buffers.

You mean to activate is to display their help-echo?
