Re: Org and Hyperbole
i am interested in whether hyperbole can inspire org. or maybe spin off stuff that is useful for org. i find org-link-minor-mode to be really useful. limited, but useful. does tses too. i use it in non-org files to link to other places in the same file, mostly. also i insert the reverse link. but i also use org id links to link to org. which, bidir is manual. also external links. idk about hyperbole, but i really like the idea of emacs being able to link all types of files and maybe even file-less buffers all around. bidirectionally. also annotate, with and without modifying the annotated file, with org as backend. i like nonbreakable links. org-id is great, might be useful in such a pan-emacs setup via links similar to extensible syntax id marker links so that it is nonbreakable and bidirectional and controllable, all without manual maintenance. those would also allow graph-theoretical stuff but i don't think i need that. except bidirectional links and lists of links, perhaps traversable via emacs's standard next-error mechanism or something similar. i noticed something a bit peculiar recently. i did org-store-link in a non-org file and a properties drawer was created at top [maint]. idk if hte org-id system will remembver that indefinitely or not; file moves might be an issue. -- The Kafka Pandemic A blog about science, health, human rights, and misopathy: https://thekafkapandemic.blogspot.com
Re: Org and Hyperbole
I just wrote recalc today as a demo so people can extrapolate what they might do with Hyperbole (calc was handy in my head since I wrote it for Ober, the Java version of the Oberon environment). WIth buttons that restore the point to where it was when you clicked, you can make them operate on the current selection (it looks like Hyperbole might not save the region though so maybe more function advice is needed for that). This makes reusable "menu bars" possible: (changing recalc to find the table at point instead of using the location of the button). Highlight a region and shift-middle-click on cut/copy/paste to do that action on your selection. This also lets you use button bars in other frames (acting even more like a real menu bar). Buttons could also parse contextual information in the button buffer (and/or the active buffer), something like org-mode properties, that could influence how the buttons behave. Other buttons could edit this information to give you document-based behavior. For instance, a button-buffer (like the menubar) could have behavioral information like this: : 4 : left Clicking "left" could toggle it between the different types of justification (left, right, center, full) and clicking on could justify the current paragraph. Clicking could change the indentation of the current file (if it's a program, it could analyze for the current indentation and then change it to the desired indentation). Just thinking out loud here -- this is the sort of thing Ober did and Hyperbole looks like a framework that makes it not too hard to do that for Emacs. -- Bill On Wed, Jun 22, 2022 at 10:26 PM Bill Burdick wrote: > No idea. > > > -- Bill > > > On Wed, Jun 22, 2022 at 10:23 PM David Masterson > wrote: > >> Bill Burdick writes: >> >> > Here's a hyperbole-org integration that lets you use org-mode tables >> > outside of org-mode files.

Re: Org and Hyperbole
Anywhere you use a link or button, you can probably use an emacs command instead. I think maybe the value of links and buttons is that they're explicit. It's a reminder in the text and you don't have to learn it. One thing I noticed in my little "recalc" exercise is that Hyperbole really really wants the cursor to stay on the button. I used function advice to make the cursor stay where it was when you clicked the button. This allows "menubars" to work, lists of buttons that can operate on the text without warping the cursor to the buttons. This is how Oberon and WIly work and I think Hyperbole (for my use cases anyway) will benefit from this usage style. -- Bill On Wed, Jun 22, 2022 at 6:15 PM Russell Adams wrote: > On Mon, Jun 20, 2022 at 05:26:30PM +0200, Russell Adams wrote: > > Is there some keen feature I'm missing?

May `org-mks’ be reused instead to avoid proliferation variants of rather similar UI code? Well, the thing here is that I’m explicitly trying to mimic the file-local-variable dialog, and since a general form isn’t exposed by Emacs, a little bit of proliferation seems like the best option to me. From my point of view the result is rather close (prompt should be adjusted): (let ((uri "https://orgmode.org;)) (org-mks nil (format "An org-mode document would like to download %s, which is not considered safe.

By state I mean some structure opaque to menu package. It just receives
it from caller as an optional argument and (when given) later passes it
to handler. Maybe it is alien approach in LISP, but in C (where closures
are impossible) it is a widely used technique. Functions having callback
argument usually have another void* one that is later passed as an
argument of the callback function in addition to other data.
(org-buffer-menu
'(("a" "Option A" (1))
("b" "Option B" (2)))
:handler
(lambda (entry state)
(message "value %S state %S" (nth 2 entry) state))
:state
'(1 2 3))
Menu caller does not care whether some buffer is created to present
menu. Menu has no idea what state may contain, it just passes it to the
handler. When menu is implemented as a buffer with keymap then state is
stored as a buffer-local variable.
As to your current implementation of org-select, I do not like that it
is responsibility of caller to create different buffer names to enable
multiple instances of menu. I would prefer to control single/multiple
instances through a boolean argument of org-select.
Arthur, I see that I should response to more your comments. However I am
unable to identify source of disagreement, likely it is some different
assumptions. That is why I decided to concentrate on a couple of

I am liking the idea of implicit buttons more and more, and I see a few applications of this concept that I can find very practical. To play around with the defil function, which you recommend in your email, I've tried defining some 'contextual help' for LaTeX and Org. Specifically for Org it has occurred to me to convert some keywords into implicit buttons that point to the info pages. Something like this: #+begin_src emacs-lisp (defil org-attr-latex "#+" ":" "attr_latex\\|caption" (let ((el (org-element-at-point))) (cond ((eq (org-element-type el) 'src-block) (lambda (x) (info "(org)Source blocks in LaTeX export"))) ((eq (org-element-type el) 'table) (lambda (x) (info "(org)Tables in LaTeX export"))) ((eq (org-element-type el) 'plain-list) (lambda (x) (info "(org)Plain lists in LaTeX export"))) ((eq (org-element-type el) 'paragraph) (lambda (x) (info "(org)Images in LaTeX export"))) ((eq (org-element-type el) 'verse-block) (lambda (x) (info "(org)Verse blocks in LaTeX export"))) ((eq (org-element-type el) 'special-block) (lambda (x) (info "(org)Special blocks in LaTeX export"))) ((eq (org-element-type el) 'example-block) (lambda (x) (info "(org)Example blocks in LaTeX export"))) ((eq (org-element-type el) 'quote-block) (lambda (x) (info "(org)Quote blocks in LaTeX export")) (defil org-attr-html "#+" ":" "attr_html\\|caption" (let ((el (org-element-at-point))) (cond ((eq (org-element-type el) 'table) (lambda (x) (info "(org)Tables in HTML export"))) ((eq (org-element-type el) 'paragraph) (lambda (x) (info "(org)Images in HTML export")) (defil org-options-kw "#+" ":" "options" (lambda (x) (info "(org)Export Settings") (occur "‘OPTIONS’"))) #+end_src I've also discovered the defib function, which allows you to define implicit buttons using predicates, instead of just using regular expressions and delimiters.

Re: Org and Hyperbole
Here's a hyperbole-org integration that lets you use org-mode tables outside of org-mode files. Shift-middle-click a "recalc" button and it will recalculate the table right under it (this idea is from an old version of the Oberon environment I wrote in Java, by the way). Here's the code: (defun bill/calc (end) (goto-char end) (re-search-forward "\n") (when (org-at-table-p) (org-table-analyze) (let* ((table-start (point)) (rows (1- (length org-table-dlines))) (table-end (re-search-forward "\n" nil t rows)) (inside (<= table-start action-key-depress-prev-point table-end))) (when inside (goto-char action-key-depress-prev-point) (org-table-maybe-eval-formula)) (goto-char table-start) (call-interactively 'org-table-recalculate) (org-table-align (defib recalc () "recalculate a table" (save-excursion (let* ((pos (point)) (eol (progn (re-search-forward "\n") (point))) (bol (progn (re-search-backward "\n" nil t 2) (1+ (point (start (progn (goto-char pos) (re-search-backward "<" bol t))) (end (progn (goto-char pos) (re-search-forward ">" eol t ;;(message "pos: %s, prev: %s" (point) action-key-depress-prev-point) (and start end (string-match " ].*" (buffer-substring start end)) (hact 'bill/calc end) Here's an example table you can put anywhere. Just shift-middle-click on it to recalculate the org-mode table. Also, if you type a formula (and keep the cursor on the same line) and then shift-click recalc, it'll handle the formula: | a | 12 | | a | 5 | #+TBLFM: @1$2=3*4::@2$2=2+3 -- Bill On Wed, Jun 22, 2022 at 1:38 PM Juan Manuel Macías wrote: > Hi David, > > David Masterson writes: > > > I haven't touched Hyperbole in ...decades...?

Menu should and application should be separated in my eyes. Menu is just a graphical/audio? presentation of selectable choice to the user. As such it should display choices, let user pick a choice, and return to the application the picked choice. Compare to completing-read, or org-mks. I don't think we should mingle application states and menu states. However, there is a slight complication compared to completing-read or org-mks in regard that those are used to make only one selection and exit, while this menu is supposed to be used that way, or to be used in a way that it survives multiple selections. To me this seems as clearly per menu entry behaviour. For exmaple in org-agenda menu, some actions will make menu exit, while some will keep the menu alive (for example '*'). One solution is to have some flag passed per entry to signal to the menu to kill itself upon selection. The other one, the easier, is to let the applicaiton code handle the menu kill. I took the second one to minimize on number of flags that needs to be passed and documented, but I agree it is not the cleanest way, so I can change to use a flag if it is considered a better option. > Global variables are certainly not an option because such approach does not > allow several instances of menu created in parallel.

I definitely agree. Designing a good API is hard. I personally always think that frameworks should not be designed in advance. I am more of a pragmatic, and prefer to see actual working use-cases and design a framework after the experience, not try to desing a framework by guessing the potential use-cases. That is why I said that I am not interested in turning this into a framework. I have try to design here something that can be used to implement existing org-capture, org-agenda & co on top of it. > That is why I consider the following aspects of menu design as essential ones: > - A clearly determined way to pass some state from a function that requests > creation of menu to handlers of menu items.

Thanks for all the interesting facts about hyperbole. I hadn't looked at the package source code info yet, and didn't know that this is all the work of one person. I also thought hyperbole was more recent... It certainly has some interesting stuff. In what way is KOutline more powerful than Org? Do you think there is any useful feature of KOutline that could be incorporated into Org? So far I've been able to find a couple of practical uses for this package in my workflow. The whole window control system is very powerful, although it would have been better if it had been a single separate package, IMHO. Implicit links have a lot of potential. For example, I've managed to define some buttons for LaTeX, which recognize LaTeX commands and environments and lead to the local TeX live documentation or tex.stackexchange.org. It's like giving a LaTeX document a sort of hover help. This could also be done in Org, by defining some patterns as implicit buttons to lead to Org info pages. Best regards, Juan Manuel

The idea here is that when this is done interactively the user will be aware of the URL this is being applied to, and so it isn’t a risk.

Well, the thing here is that I’m explicitly trying to mimic the file-local-variable dialog, and since a general form isn’t exposed by Emacs, a little bit of proliferation seems like the best option to me. >> +;; Set up the contents of the *Local Variables* buffer. > > I am in doubts concerning “once”.

Oh, and I should change that comment to “Set up the contents of the *Org Remote Resource* buffer.”. >> + (propertize “n” ’face ’error) >> + “ to skip this resource.”) > > From “skip” I do not expect aborting of export. Hmm, the “skip” action isn’t determined by the “is it safe” functions, but some wording that doesn’t sound completely safe at least would be good. > I have an idea but unsure if it should be implemented.

I guess thatʼs what you get > with the default value of `org-safe-remote-resources’, but maybe it > makes sense to be explicit? That isn’t the behaviour. `prompt' doesn’t /always/ prompt, just when the resource in question is not considered safe according to `org--safe-remote-resource-p'. So, `prompt-always' would be something else, but one can easily make prompt behave that way by setting `org-safe-remote-resources' to nil, so I don’t think it warrants an extra option. All the best, Timothy

This is possible with Beamer, see This is a bit hacky but see attached file. The trick is to end the previous frame explicitly, create the frame with the desired background, and then start explicitly a new frame but which is not shown in presentation mode. The ending of the previous frame is fragile as there may be other environments that should be closed so you will have to be careful.
