For example, bind this function to another shortcut? By the way, I'm using spacemacs. # Answer > 1 votes You can rebind `set-mark-command` to anything (`C`-`.` in the example) ``` (global-set-key (kbd "C-.") 'set-mark-command) ``` or ``` (define-key 'global-map (kbd "C-.") 'set-mark-command) ``` Alernatively, without having to rebind anything: * it's also bound to `C`-`@`. * You can exchange point and mark `C`-`x``C`-`x` -- if you're not using the current mark already it'll be the same. * You can mark the paragrah, or org-element with `M`-`h`, move the point to first line you want, then reduce region exchanging point and mark first, and moving the point again to the desired end. Sounds far more complicated than it is, but sometimes it's faster than any other method. Sure there are more ways, but I do use those. --- Straight to the example, to select directly only the src block contents you can use `org-babel-mark-block` which is bound to `C`-`c` `C`-`v` `C`-`M`-`h`. Sure not really the most friendly shortcut for the memory muscle. Thanks to bertfred for pointing it in this answer --- Tags: spacemacs ---

What´s wrong? # Answer > 31 votes In order for org-mode to show events scheduled or with a deadline in the agenda-view, the org-file containing these events must be listed in the variable `org-agenda-files`. While one can customize this variable, the more practical way is to invoke the function `org-agenda-file-to-front`, which is commonly bound to `C-c [`. For further details see the org-mode manual: Agenda files # Answer > 5 votes Perhaps this answer will help future Doom Emacs users who run into this problem. I think it had to do with the order in which multiple configuration files are loaded. My solution was to put the following in `config.el`: ``` (after! org (setq org-agenda-files '("~/org/inbox.org" "~/org/gtd.org" "~/org/tickler.org"))) ``` The `after! org ...)` is the important bit. It will set the property after going into org mode, whereas, I believe, Doom is setting its own default location on startup. # Answer > 1 votes Try adding a ':' in front of SCHEDULE.

When I maximize the Emacs frame, it uses the full width of the screen, no background showing. But if I e.g. snap-to-edge (in XFCE), it shows a little "margin" of background outside the frame. And if I drag to resize, it always over- or undershoots the edge – it looks like it wants to always resize by whole lines/characters. Is there a way to have a 50% size Emacs frame that aligns with the edge of the screen? (I'm using 20170203:93058-ce88155-emacs-25.1~ubuntu16.04.1) Mousepad can take exactly 50% width and 100%height, with height from the top of the screen down to the panel: Emacs seems to overshoot/undershoot: When I "snap" Emacs to the edges with XFCE, it fits the width on my laptop, but not on my external monitor. It never matches the full height. # Answer Reading `C-h f set-frame-width` as mentioned by user @lawlist, I saw a mention of `frame-resize-pixelwise`. Putting this in .emacs.d/init.el ``` (setq frame-resize-pixelwise t) ``` makes the window "snap" to the right height in XFCE (haven't tried on my external monitor yet, so don't know if it gets the exact right width too); it also snaps to the right height when I set the height with my wmctrl scripts. > 6 votes # Answer Here is an example using some of the functions mentioned in the comment and link underneath the original question hereinabove: ``` (let ((frame (selected-frame)) (one-half-display-pixel-width (/ (display-pixel-width) 2))) (set-frame-width frame one-half-display-pixel-width nil 'pixelwise) (set-frame-position frame 0 0)) ``` --- FYI: Feature request #21415 was incorporated into Emacs 25 -- frame creation may now include a pixel specification -- this includes items such as the `initial-frame-alist`, `default-frame-alist`, and the `make-frame` function.

For example `(set-frame-size (selected-frame) 300 300 t)` would set the currently selected frame size to 300x300 pixels.

Maybe Zotero should export differently? Not sure if this helps but I setup the variable ``` (setq bibtex-completion-library-path "~/cloud/Papers/") ``` to the path which contains all my papers. And then the bibtex entries only have the name of the file (with no path) in them. Given your setup you could debug by calling both ``` (bibtex-completion-pdf-open-function <fullpath>) (bibtex-completion-pdf-open-function (concat <dirpath> <pdfname>)) ``` trying to substitute in the appropriate values.

thread-58239	https://emacs.stackexchange.com/questions/58239	ein org mode results raw drawer	2020-05-02T20:58:57.270	# Question Title: ein org mode results raw drawer I am trying to use `ein` with `org-mode` in emacs but I am having problems with exporting the results. Here is a very simple example: ``` #+BEGIN_SRC ein-python :session localhost :results raw drawer :exports both import pandas as pd x = pd.DataFrame({'Num': a, 'Text': ['a', 'b', 'c', 'd']}) x #+END_SRC :results: Num Text 0 1 a 1 3 b 2 5 c 3 12 d :end: ``` So, using `:results raw drawer` writes the results inside `:results:` block, and are not shown when I export to html. If instead I use `:results output` or `:results value` it simply prints `[...]` (no data). And `:results raw` prints the following ``` #+RESULTS: b2757239-e41b-4626-9aef-d2abf968c1ee Num Text 0 1 a 1 3 b 2 5 c 3 12 d Num Text 0 1 a 1 3 b 2 5 c 3 12 d [....] [....] ``` Which of course does not look good in the html file. The question, what is the best way to print results to export in html? # Answer Probably the simplest way to get reasonable looking results when exporting is to wrap the results in an example block, which will export it as pre-formatted text: ``` #+BEGIN_SRC python :session localhost :results value :wrap example :exports results import pandas as pd x = pd.DataFrame({'Num': 3, 'Text': ['a', 'b', 'c', 'd']}) x #+END_SRC #+RESULTS: #+begin_example Num Text 0 3 a 1 3 b 2 3 c 3 3 d #+end_example ``` (BTW, I had to change the value of the `'Num'` entry in the dataframe to avoid a traceback). Another possibility is to have the python code produce an HTML table which you then export verbatim. You can have Pandas produce the HTML table for the dataframe by using `x.to_html()` instead of `x` in the source block. Then, the trick is to wrap the results appropriately so that the export does not muck around with the HTML that is produced. That is accomplished by wrapping the results in a `#+BEGIN_EXPORT html ... #+END_EXPORT` block - see the Quoting HTML tags section of the manual. The `:wrap` header can be used for that as well: ``` #+BEGIN_SRC python :session localhost :results value :wrap export html :exports both import pandas as pd x = pd.DataFrame({'Num': 3, 'Text': ['a', 'b', 'c', 'd']}) x.to_html() #+END_SRC #+RESULTS: #+begin_export html <table border="1" class="dataframe"> <thead> <tr style="text-align: right;"> <th></th> <th>Num</th> <th>Text</th> </tr> </thead> <tbody> <tr> <th>0</th> <td>3</td> <td>a</td> </tr> <tr> <th>1</th> <td>3</td> <td>b</td> </tr> <tr> <th>2</th> <td>3</td> <td>c</td> </tr> <tr> <th>3</th> <td>3</td> <td>d</td> </tr> </tbody> </table> #+end_export ``` Exporting this to HTML produces a "real" HTML table. I would recommend that you avoid `raw` if possible (and in this case you can): `raw` does not let Org mode know where the results begin and end, so evaluating the block repeatedly adds more and more crud that you have to clean up manually. > 1 votes --- Tags: org-mode, org-export, org-babel, ein ---

I think I have to do a `incode-decode-map` (https://stackoverflow.com/q/36613839/2402577) but I wasn't able to do it. # Answer > 1 votes # tl;dr @drew is right, you have a conflict. Use `C-backspace` in Emacs to delete the word to the left of the point. At your shell command like use `C-w` to do the same. # Long answer @Drew is correct, you have a conflict between iTerm and Emacs. Unfortunately there's not much you can do about that, so let's focus on what you want to do, "delete word". As you've discovered, Emacs has a "delete word" function, `backward-kill-word`. This will delete the word<sup>1</sup> to the left of the point. By default `backward-kill-word` is bound to `C-backspace`. Now, when you have iTerm open in front of you, and you're at your shell command line, you can also "delete word". By default this is bound to `C-w`, in both `bash` and `zsh`.<sup>2</sup> Generally both `bash` and `zsh` have "emacs keybindngs" by default, so general movement and editing use the same keys. "Delete word" is one place where they differ. Like in Emacs, you can rebind keys in your shell, but unifying your keybindings so you have a common "delete word" key in your shell and in Emacs isn't that simple. In Emacs, rebinding `backward-kill-word` to `C-w` will step on the default binding of `kill-region`, which I don't recommend. Binding `C-backspace` in your shell isn't that simple, or simple of a conflict. Generally, in your shell, when you press the backspace key, the shell does not receive a "backspace event" like Emacs does. The shell receives `C-?`<sup>3</sup> and this is bound to `backward-delete-character`. This is also something you don't want to overwrite for obvious reasons. ## Recommendations While you could bind "delete word" to a single unused key in Emacs and your shell, say `C-o`<sup>4</sup>, I strongly recommend you don't. The same goes for any of the basic movement and editing keys. (up, down, left, right, forward-word, backward-word, kill-word, kill-backward-word, end-of-line, beginning-of-line, etc.) You'll always be able to sit at a "unix" computer and get things done. There's nothing like sitting at a customer's system, and they're quite literally breathing down your neck to fix something "now!", and you choke because your "weird" keybindings and aliases are missing. (Pro tip.) Obviously if you have a real need to rebind keys, do it. But learn the defaults too. -- \[1\]: The Emacs definition of a "word" depends on the syntax table active in the buffer you're visiting. For the sake of discussion we'll just assume a "word" is a group of letters and numbers by characters that are not letters or numbers. \[2\]: In `bash` `C-w` is actually bound to `unix-word-rubout` and can be described as "delete the previous group of letters and numbers bounded by whitespace" and is closer to `zsh`'s `backward-kill-word`. `bash`'s `backward-kill-word` and can be described as "delete the previous group of letters and numbers bounded by charactars that are not letters or numbers" and is bound to `Escape-Control-Backspace`. \[3\]: Your shell could receive `C-h` which is also bound to `backward-kill-character`. It's something you might see on other older "unix" systems.

But it sounds like it is capturing the keys you specified, which you want, in general. You just don't want it to do that when Emacs has the input focus.

thread-58267	https://emacs.stackexchange.com/questions/58267	What function will return the total EFFORT of the subtree at point?	2020-05-04T14:13:47.127	# Question Title: What function will return the total EFFORT of the subtree at point? I am looking for an elisp function that will return the total EFFORT of the subtree at point. By "total EFFORT" I mean the "Sum times" value that would be produced by giving the subtree a :COLUMNS: property of %EFFORT{:}, and then switching the subtree to column view, and looking at the column value. So in the example below, if point is on headline 'test' and I call hypothetical function get-subtree-effort, the function would return "0:14". ``` * test :PROPERTIES: :COLUMNS: %EFFORT{:} :END: e1 :PROPERTIES: :Effort: 0:07 :END: e2 :PROPERTIES: :Effort: 0:07 :END: ``` # Answer > 1 votes Here's one way: ``` (defun to-integer-mins (s) "Convert a string in HH:MM format to integer minutes." (if s (seq-reduce (lambda (x y) (+ y (* x 60))) (mapcar #'string-to-number (split-string s ":")) 0) 0)) (defun int-to-hh-mm (n) "Convert an integer to an HH:MM format string." (let* ((h (/ n 60)) (m (- n (* h 60)))) (format "%02d:%02d" h m))) (defun get-effort() (org-entry-get (point) "Effort")) (defun get-total-effort() (int-to-hh-mm (seq-reduce #'+ (mapcar #'to-integer-mins (org-map-entries #'get-effort t 'tree)) 0))) ``` If you do `ESC ESC : (get-total-effort) RET` with point at the "test" headline, you will get `00:14`. The main point here is the call to `org-map-entries`: ``` (org-map-entries #'get-effort t 'tree) ``` which will traverse the subtree, apply the `get-effort` function on each headline and accumulate the results in a list. The `get-effort` function checks for an `Effort` property and returns it if found (if not, it returns nil). If you run the above call to `org-map-entries` at the top-level headline with `ESC ESC : (org-map-entries #'get-effort t 'tree) RET` you will get: ``` (nil "0:07" "0:07") ``` the sequence of Effort values at each headline of the tree. All you have to do now is add them all together, but that is a bit messier than it sounds: you have to convert the strings to numbers (the number of minutes for each one), add them together to get the total number of minutes and then convert the numeric result to a string in `HH:MM` format. There are many ways to do that, but they have nothing to do with Org mode: they are generic data manipulations using standard emacs-lisp functions. I chose to implement them in functional style using `mapcar` and `seq-reduce` but they can be implemented using a more imperative style using loops instead. --- Tags: org-mode ---

When running `ert` tests, the seem to be run by default in `string<` order. For instance running tests ``` (require 'ert) (ert-deftest t1111 () (print 'AAAA)) (ert-deftest t3333 () (print 'BBBB)) (ert-deftest t2222 () (print 'CCCC)) (ert-run-tests-batch :new) ``` will print ``` ;; Actual output ;; Wanted output AAAA AAAA passed 1/3 t1111 passed 1/3 t1111 CCCC BBBB passed 2/3 t2222 passed 2/3 t3333 BBBB CCCC passed 3/3 t3333 passed 3/3 t2222 ``` For interpretation it would be helpful to guarantee the order of the tests. How can this be achieved? # Answer > 1 votes As far as I could tell, it is not possible to cause the selectors `t` (universe) or `:new` to run tests in the order of definition. The `(member TEST1 TEST2 ...)` selector however executes tests in the order specified. For my tests I am therefore using one of two workarounds (both written ad-hoc and not tested for balanced parentheses): ## 1. Wrapper, that records the tests in a list. ``` (defconst NAMESPACE-test-list nil) (defmacro NAMESPACE-deftest (name &rest args) `(progn (ert-deftest ,name ,@args) (setq NAMESPACE-test-list (nconc NAMESPACE-test-list (list ',name))))) ;; TEST DEFINITIONS (ert `(member ,@NAMESPACE-test-list)) ``` ## 2. Scan file for ert-deftest with regular expression search. ``` ;; TEST DEFINITIONS (ert (cons 'member (with-temp-buffer (insert-file load-file-name) (cl-loop while (search-forward-regexp (rx bol "(ert-deftest" (+ blank) (group-n 1 symbol-start (? nonl) symbol-end))) nil t) collect (intern (match-string 1)))))) ``` ## 3. Numbered test names Alternatively, the alphabetic order of the tests can be (ab?)used, e.g. ``` (ert-deftest NAMESPACE-001:some-function () ...) (ert-deftest NAMESPACE-002:other-function () ...) ... (ert :new) ``` or ``` (defvar NAMESPACE-test-counter 0) (defmacro NAMESPACE-deftest (name &rest args) `(ert-deftest ,(intern (format "NAMESPACE-%03d:%s" (cl-incf NAMESPACE-test-counter) name)) ,@args)) (NAMESPACE-deftest some-function () ...) (NAMESPACE-deftest other-function () ...) ``` Both variants have serious downsides however: The first variant causes maintenance issues. Want to reorder the test definitions? Now we also need to renumber all tests, which in turn confuses the version history. * The second variant breaks interactive lookup of the test definition from the `M-x ert` buffer. --- If I have just missed a setting, that enables "execute in definition order", I'll be happy to hear of it however. --- Tags: testing, ert ---

See the function definition below: ``` (defun windows-path-backwards () (interactive) (skip-chars-backward "a-zA-Z0-9\\\\_\\-:")) ``` In other words, `:` is not important in itself, it just happened to be one of two characters surrounding a `-` in the nonfunctioning example given in the question. --- Tags: regular-expressions ---

I turn it on with: ``` (prettify-symbols-mode t) (global-prettify-symbols-mode t) ``` And I'm trying to change the way python source code looks with the follownig setup: ``` (add-hook 'python-mode-hook (lambda () (push '("2" . ?²) prettify-symbols-alist) (push '("_x" . ?ᵪ) prettify-symbols-alist) (push '("sum" . ?∑) prettify-symbols-alist))) ``` This works, but not consistently. For example, `x2 x_x and sum(x)` all look good. The inconsistent part is that x\23 maintains the superscript 2, but the 3 is regular. But if I say `x2+2`, or `x2,` then the `2` is not pretty (and it should be). I'd like the 2 to only be superscript when it is followed by certain characters (space, plus, comma, etc.). Alternatively, not superscript if followed by \[0-9\]. Meanwhile, sum behaves correctly. `sum(`, `sum2`, `sum+`, and others are pretty (as they should be) and `summer` is not (correctly). # Answer According to the documentation for `prettify-symbols-alist`, you cannot use regular expressions here: > Each element looks like (SYMBOL . CHARACTER), where the symbol matching SYMBOL (a string, not a regexp)** will be shown as CHARACTER instead. `pretty-symbols-mode` uses `regexp-opt` internally, which creates a big regular expression from all the strings in the car position of each of the alist pairs.

So it can let you do some cool stuffs like y superscript star index i ``` (setq prettify-symbols-alist '(("yy" . (?y (tr . Bc) 1645 (br . cr) ?i)))) ``` see the `C-h compose-region`. I'm not going to lie it took me a long time to figure out how to do it and I still have many questions but my understanding of the doc says that the N, are the characters. 0, 2, 4, and the N+1 are the composition rules.

And I use Emacs since long time ago for everything I write (not only Literature related texts, but for programming, task management, etc.). I would like to set up a synonyms service to be used from inside Emacs. And I needed for Spanish. I know there are some very good ones for English, but I couldn't find anything for Spanish. Is there anyone that knows one of this services, and how to set them up with one of the already known Emacs packages? An alternative would be to try to find such a service with a REST API, and try to set up some functions to request synonyms for the word at point to this service using the REST interface. I'm an experienced programmer, but not with Emacs Lisp, and I don't know if this is two much for me. Any hints on libraries of ways to do this, if an already existing solution is not available? # Answer Following the suggestion of Muihlinn I used www-synonyms.el, and it works quite well. You have to log onto altervista to get the `key` that you have to include in your set up (you can do it with a Google account). Then, I put in my init.el (or .emacs): ``` ;;;---{{{ Sinonimos }}}------------------------- (require 'www-synonyms) ;; Get key here: http://thesaurus.altervista.org/mykey (setq www-synonyms-key "<my-key>") ;; any of: it, fr, de, en, el, es, no, pt, ro, ru, sk (setq www-synonyms-lang "es_ES") ;; Set C-x w as key binding to insert a synonym of the word at place (global-set-key (kbd "\C-x w") 'www-synonyms-insert-synonym) ``` Some remarks: I put `es_ES`, instead of `es`, since this is the key of the mapping in the code. In addition, I have set Control-x w as the keybinding to call the function to show the possible synonyms of a given word. Also, with my Emacs version and setup, and my OS, I had to add the following at the beginning of the `www-synonyms.el` code file (and re-byte-compile the file): ``` (require 'cl-extra) ``` and change a call to `mapcan` to `cl-mapcan`; otherwise I get an error on `mapcan`. It works like a charm! > 1 votes # Answer You can use www-synonyms.el which is available from melpa. It takes altervista as source. Although it's functional and supports spanish, as well as a couple of other languages other than english, UI can use some help.

Suppose I rebind `C-e` (`move-end-of-line`) to `C-o` in the global-map. How can I make `C-o` the corresponding function in all modes (if it exists). So, for example, in org-mode `C-o` should be `org-end-of-line`, not `move-end-of-line`. NB: I do not simply want, in this example, `C-o` to be `move-end-of-line` everywhere. Rather I want it to be the corresponding command for that mode, which in this case is `org-end-of-line`. # Answer Not sure I understand your question. Are you asking how, in each major mode, to bind to `C-o` whatever that mode normally binds to `C-e`? If so, then in `after-change-major-mode-hook` add a function such as this: ``` (defun my-remap-C-e-to-C-o () "Remap whatever command is locally bound to `C-e` to `C-o`." (let* ((map (current-local-map)) (C-e-bind (lookup-key map (kbd "C-e") t))) (define-key map (kbd "C-o") (or C-e-bind 'move-end-of-line)))) (add-hook 'after-change-major-mode-hook #'my-remap-C-e-to-C-o) ``` If the local mode does not, itself, bind `C-e` then the `C-o` gets bound, in that mode, to `move-end-of-line`. This code does not remove the global binding of `C-e`. If you also want to do that then: ``` (global-unset-key (kbd "C-e")) ``` > 2 votes --- Tags: key-bindings ---

I have a personal orgmode file where I organize my life. Always when I open it I have to press: ``` C-c a a ``` That opens my agenda and shows to me my habits, the scheduled and deadline tasks. But it's annoying to remember it and make manually. I'd like to open my orgmode file and automatically opens my agenda overview. # Answer You can use file variables (or in this case, a pseudo-variable) to do something when you open a particular file. Add something like this at the bottom of the file: ``` # Local Variables: # eval: (progn (org-agenda-list) (split-window-below)) # End: ``` In order to avoid confirmation questions, you'll also have to set a couple of variables in your init file: ``` (setq enable-local-eval t) (setq safe-local-eval-forms '((progn (org-agenda-list) (split-window-below)))) ``` I still find this annoying because the agenda splits the window and so I end up with two small windows: one for the file and one for the agenda (in addition to the window that I started with). But if I don't split the window, then the file gets opened in the agenda window and hides it. Despite that, I hope this helps. # Update: A better alternative Here's a slightly different method, using `other-window` to switch windows between opening the agenda and opening the file. The variable settings are like this: ``` (setq enable-local-eval t) (setq safe-local-eval-forms '((progn (org-agenda-list) (other-window 1)))) ``` and the file-locals section in the file itself becomes: ``` # Local Variables: # eval: (progn (org-agenda-list) (other-window 1)) # End: ``` I think this behaves better and in the few tests I did (with just a couple of windows), it seemed robust. I'm not sure whether I would like it if I had a lot of windows open however. > 3 votes --- Tags: org-mode, org-agenda ---
thread-41402	https://emacs.stackexchange.com/questions/41402	Any advice? - Struggling with text reuse in emacs buffer	2018-05-09T07:27:36.783	# Question Title: Any advice? - Struggling with text reuse in emacs buffer I'm basically a level 0 emacs/orgmode user, trying to get the hang of Emacs/Orgmode. Doing this like for the 5th time already, as most Emacs beginners obviously. I have this feeling I'll like and be happy with the Emacs world, but oh well it takes a lot of patience. So I'm trying to do things little by little. So I'm trying to do something that seemingly should be quite doable but can't understand how to make it work. The idea is to reuse predefined text within a buffer. I think that what I want is to define kind of "text variables" or "snippets" and reuse that in my text later on. Let's say I'm writing some specification for my laptop. I'd like to something like define a term in buffer (don't pay attention to syntax, it's just my interpretation), let's say "Thinkpad T470p, black, with dedicated graphics card, XYZ". So I'd define this term at the beginning of my buffer. The term, presumably, would have a label/name (not sure if this is the correct term) and some value. Let's say, the value is as above and label is "MyThinkPad". Then when writing text, I'd like to start writing "MyThinkPad" and that would auto-insert the previously predefined text "Thinkpad T470p, black, with dedicated graphics card, XYZ" at the cursor position. AND what is most important - if I change value of this "variable" in the buffer , that should auto-update throughout the buffer. I'm not sure what is the right direction to look. I have a feeling this has to do with some of these "#+NAME" or "#+LABEL", or citations, or local variables, or something of that sort. After reading online resources and trying out various ideas, I'm stuck and turning to community help. Really looking forward to your suggestions. Thanks in advance! # Answer Tl;dr Use Yasnippet Hi, from the use case you describe, Yasnippet could provide a solution for you. On the EmacsWiki page for this project it is explained that: > \[Yasnippet\] allows you to type an abbreviation and automatically expand it into function templates. In your case, the function template would just be a constant string. --- Detailed Example I could not find a simple example on how to make yasnippet work on my machine so I decided to add a little bit more detail to this answer myself. 1. I downloaded the yasnippet package to `~/.emacs.d/lisp/yasnippet` and put the following lines in my `~/.emacs.d/init.el`: ``` (require 'yasnippet) (setq yas-snippet-dirs '( "~/.emacs.d/snippets" )) (yas-global-mode 1) ``` This tells yasnippet to look in the folder `~/.emacs.d/snippets` for your personal snippets. 2. Inside the `~/.emacs.d/snippets` directory, I have created another directory called `org-mode`. The important point to notice is that yasnippet apparently expects the name of the folder to be equal to the name of the (minor-) mode you wish to use later. 3. In the `~/.emacs.d/snippets/org-mode` directory create a file `test` with the following content: ``` # name: thinkpad # key: thinkpad # -- "Thinkpad T470p, black, with dedicated graphics card, XYZ" ``` Now, whenever you are editing a file with orgmode, just type `thinkpad`+`<TAB>` and it will automatically expand the string `thinkpad` to `"Thinkpad T470p, black, with dedicated graphics card, XYZ"` as desired. Obviously you can later change the string to something else if you like. > 1 votes --- Tags: org-mode ---
