What is the status of ob-maxima.el? Is this a bug?
Hi list,
what is the status of ob-maxima.el? Is it considered to be functional?
If yes, what am I doing wrong? If no, should I file a bug report about
the problem below?
If I eval these two sexps and then execute the code block below them
with `C-c C-c' - obs: I added some indentation for clarity,
(setq org-confirm-babel-evaluate nil)
(require 'ob-maxima)
#+begin_src maxima
2+3;
#+end_src
then I get this "#+RESULTS:" block when the first "maxima" found in
the $PATH is /usr/local/bin/maxima, that is a script that runs a
Maxima compiled from the git sources a few days ago,

I found, by running this, (find-orggrep "grep --color=auto -nH --null -e read-char-exclusive *.el") that `read-char-exclusive' appears in 29 places in the Org source, and I was thinking of replacing some of them by a `my-read-char-exclusive', and then set a breakpoint in `my-read-char-exclusive'... I have just tried running this in an Org file, (debug-on-entry'read-char-exclusive) (eek "C-c C-e") (cancel-debug-on-entry 'read-char-exclusive) and after running the first two sexps above with my favorite variant of `C-x C-e' the backtrace showed me that this (find-efunction 'org-export--dispatch-action "read-char-exclusive") is the occurrence that matters - the one inside `org-export--dispatch-action'. I'll play more with that soon! Cheers =), Eduardo Ochs http://angg.twu.net/#eev

Hi Ihor, (3) _is_ my experience with the Org mailing list. What I meant by "the developers like your questions" was roughly: "recognizing that that person deserves help, and giving him tools that would let him solve his problems in hours instead of in months or years". For example, in this thread https://lists.gnu.org/archive/html/emacs-orgmode/2021-12/msg00674.html no one considered that if I was asking that then maybe it would be a good idea to make `org-export-dispatch' more hackeable by beginners... For example, someone could have said "can you try this? Copy that function to other file, replace its lines foo and bar by the lines plic and bletch, and use the ideas in these two blog posts to debug and inspect its data structures"... but no, that didn't happen - I've asked lots of technical questions here over the years and never got detailed answers like that, only answers whose technical details _were kept as short as possible_, and whose explanations were much closer to "in English" than to "in Lisp". A few days ago I added subtitles to my video about "Org for Non-Users". The links are here, http://angg.twu.net/2021-org-for-non-users.html and some people will prefer to just read this: http://angg.twu.net/eev-videos/2021-org-for-non-users.vtt http://angg.twu.net/SUBTITLES/2021-org-for-non-users.lua.html It explains with examples how a "non-user" thinks, and it shows what I mean by "explanations in Lisp".

Did you find a way to replace the blocking code by something else? I stumbled on exactly the same problem some months ago, and it drove me nuts: https://lists.gnu.org/archive/html/emacs-orgmode/2021-12/msg00674.html Edrx 1 https://lists.gnu.org/archive/html/emacs-orgmode/2022-02/msg00098.html Ihor 2 https://lists.gnu.org/archive/html/emacs-orgmode/2022-02/msg00106.html Edrx 3 https://lists.gnu.org/archive/html/emacs-orgmode/2022-02/msg00111.html Ihor 4 http://angg.twu.net/e/org.e.html#org-export-dispatch My conclusion was that Org is much harder to learn than I thought. It's easy to learn if: 1) you're a "user", or 2) you know a lot about debugging Emacs, or 3) the developers like your questions. My holidays have just started, and I'm planning to work on (2). Btw, at some point I gave up trying to find the functions that the dispatcher calls, and I just defined this "function with a very short name" that [c]ompiles the current .org file to HTML: (defun c () (interactive) (eek "C-c C-e h h")) Refs: (find-eev-quick-intro "3.

Hi Jean Louis, Sorry, I will have to put that on hold until my holidays... I wrote a very primitive prototype, but I never had to write much code that generates text with text properties, my friends are not interested in playing with that together with me, and I don't know where to borrow ideas from, so adding each new small feature by myself is a struggle... and right now writing code "whose inner details don't matter" is exactly the opposite of my notion of fun... =( [[]], Eduardo Ochs http://angg.twu.net/#eev

You're hiding the technical details, and I don't know how to think in these terms, sorry! =( For me your "non-Org link" is a string composed of a few substrings concatenated, and each of these substrings is either without text properties or is built using "propertize" or "buttonize". In this message https://lists.gnu.org/archive/html/emacs-orgmode/2022-09/msg00725.html I referred to those substrings as "subsegments", but I don't know what is the correct term. I am trying to factor your problem into several small functions in a way that makes each of these small functions easy to test - with one-liners if possible, like I do in the eev source code - and if we do that factoring then the function that builds the "string composed of a few substrings concatenated" that I mentioned above will not call your rcd-template-eval and will not depend on the major mode... I have the impression that the hard part _now_ is to write that function that produces that string with text properties. Once we have that we will have a clearer notion of what are the "non-Org links" that we are dealing with, and it will be easier to think on the other functions. By the way, I mentioned here https://lists.gnu.org/archive/html/emacs-orgmode/2022-09/msg00725.html that the simple Org link that I inspected had about 8 subsegments with different text properties... Org links need all that because they have to handle correctly insertions and deletions at several points, cutting and pasting, "following", conversion to fundamental mode, etc, etc... I have the impression that we can start with a prototype in which our prototype-ish non-Org links have only three subsegments, but you will have to accept that in that prototype the links won't have all the features that you want...

Let me call that sexp the "back-end" of the link. I did play with some ways to buttonize back-end sexps, and with some ways to parse the text around point to generate these back-end sexps, but I didn't find those things much fun, and in all the cases I ended up finding nice ways to solve my problems with just explicit sexps, without hiding them behind a title. So I postponed the problem behind your question - and I will deal with it again when someone who wants "back-end sexps hidden behind titles" asks me for help, or asks me to work together on their ideas. > There must be some way of quickly generating above links, do you have > such? > > Let us say you are in buffer A, you go to Emacs Lisp file at line 134, and > you just press there a key, and link is inserted in buffer A, leading > to Emacs Lisp file at line 134, you have that?

Anyway, we are clearly using different notions of simplicity - see:
https://lists.gnu.org/archive/html/hyperbole-users/2020-09/msg00013.html
and I find it enviable that you can have that kind of complexity under
the hood and still have lots of users that agree that Hyperbole is
"simple"...
Most people find eev very weird, and I have the impression that I
wouldn't have half of my (few) users if I had code like that in eev.
If the people who like to look under the hood try to understand how
M-e in eev works they will end up trying to understand how
(forward-sexp -1)
works, and then they will read the comments of scan-sexps in
syntax.c... syntax.c is impeccably well-written, and they will
probably feel that their time was very well spent, and that their
curiosity has lead them to very good places. =\

I started using GNU/Linux in the mid-90s. Before that my favorite languages were Icon and Forth. In Forth I could do AMAZING things in less than 50 lines of code, but my programs would usually become confusing and unmanageable when they grew bigger than that. There is a famous book by Fred Brooks called "The Mythical Man-Month", and one of its chapters is called "Plan to Throw One Away": https://wiki.c2.com/?PlanToThrowOneAway I took that slogan seriously. Most of the time when I realized that something that I was doing by hand could be automated I would write a first attempt to automate it - _as a prototype_, that I regarded partly a program and partly as a way to help me think how that task could be structured, and that would probably be "thrown away" if I needed a cleaner solution later. In Forth it was very easy to implement both strange interfaces and little languages, in this sense: https://wiki.c2.com/?LittleLanguage In Emacs less so, but I could still do lots of funny things using eval-last-sexp to use sexps as buttons. When we are writing throwaway code "planning to throw one away" then using tests in comments is a very good way to document the code. And when I rewrite my prototypes I usually prefer to document them using text ***AND*** executable examples rather than just text. One of the effects of using this style is that the users of eev see that they can use that style in their notes too - and with that their notes become much closer to being "executable notes", in this sense, http://angg.twu.net/eev-intros/find-here-links-intro.html than they would be if they believed that they had to write the docs of their functions as just text. You are sort of saying that having tests in comments is bad style. Well, it's not. =/ [[]], Eduardo Ochs http://angg.twu.net/#eev

Hi Robert,
That's bad news. In the last years I became a specialist on helping
people with the "non-abstract parts", usually via chat... we discuss
until we find together what are the parts that are not clear to them,
them we write tests that show how those parts work, and then we go
back to the high-level functions.
In eev the two sexp hyperlinks below
(find-efunction 'hkey-initialize)
(find-efunction 'hkey-initialize "Bind the Action Key to {M-RET}")
point to the source code of `hkey-initialize', but the second one is a
"refinement" of the first one in this sense:
(find-refining-intro)
http://angg.twu.net/eev-intros/find-refining-intro.html
I often use sequences of sexp hyperlinks, with and without
refinements, to record an "explanation" of how something is done. For
example, this block
(code-c-d "hyperbole" "~/.emacs.d/elpa/hyperbole-8.0.0/")
(find-hyperbolefile "DEMO")
(find-hyperbolefile "DEMO" "Action Key is {M-RET}")
(find-hyperbolegrep "grep -nH --null -e M-RET *")
(find-efunction 'hkey-initialize)
(find-efunction 'hkey-initialize "Bind the Action Key to {M-RET}")
(find-ekeymapdescr hyperbole-mode-map)
(find-ekeymapdescr hyperbole-mode-map "M-RET")
(find-ekeymapdescr hyperbole-mode-map "M-RET" "hkey-either")
(find-efunction 'hkey-either)
(find-efunction 'assist-key)
(find-efunction 'assist-key-internal)
(find-efunction 'action-key)
(find-efunction 'action-key-internal)
(find-efunction 'hkey-execute)
(find-efunction 'hkey-execute "hkey-alist")
(find-evardescr 'hkey-alist)
(find-eppp hkey-alist)
(find-evariable 'hkey-alist)
(find-evariable 'hkey-alist "If on a Hyperbole button")
(find-efunction 'hbut:at-p)
(find-efunction 'hbut:at-p "ebut:at-p")
(find-efunction 'hbut:at-p "ibut:at-p")
(find-efunction 'ebut:at-p)
(find-efunction 'ebut:get)
(find-efunction 'ibut:at-p)
is an attempt to understand how M-RET treats hkey-alist as a kind of
program to be run...
How would you rewrite the sexps above as Hyperbole buttons?
I downloaded a local copy of
(find-hyperbolefile "FAST-DEMO")
(find-hyperbolefile "FAST-DEMO" "GNU Hyperbole Videos")
(find-hyperbolefile "FAST-DEMO" "Overview and Demo")
(find-hyperbolefile "FAST-DEMO" "https://youtu.be/WKwZHSbHmPg";)
with
(find-youtubedl-links nil nil "WKwZHSbHmPg" nil "hoandd")
Docs: (find-efunction 'find-youtubedl-links)
and I found - via the transcript -
(find-yttranscript-links "hoandd" "WKwZHSbHmPg")
Docs: (find-efunction 'find-yttranscript-links)
that starting on 5:14
(find-hypoanddvideo "05:14" "and so it's very easy to create these")
(find-hypoanddvideo "05:17" "live")
(find-hypoanddvideo "05:18" "uh interactive tutorials if you want")
you say that you can use Hyperbole buttons to create interactive
tutorials... I do that with eev all the time, but my "buttons" are
sexps.
Imagine for a moment that a group of, say, 42 Emacs users asks you to
prepare a video tutorial on how exactly hkey-alist works, because they
want to create their own extensions - button types? - and they think
that it would be nice, and useful to the world, etc, etc, if you could
record a video explaining that... would you still answer something
like this,
"then use edebug or trace commands to explore the code flow but I
wouldn't expect anyone to write that out for you"
or would you use Hyperbole to create an interactive tutorial
explaining the details, and record a video demo-ing it?

In all cases below "explain" means "explain step by step, with links to the source code and to the docs, and with sexps that inspect the data structures". 1) explain what happens when we type M-RET on this button: "subr.el" 2) explain what happens when we type: C-h h d d 3) suppose that we have a function that plays a local copy of your video "GNU Hyperbole - Overview and Demo".

Hi Robert, let me see if I can find something useful to say... Most of the people that I know who became active users of eev were "beginner programmers" when they started using eev - by "beginner programmers" I mean that their mental buffers were still quite small, and they couldn't understand well functions that were more than a few lines long. I wanted to make eev more accessible to people like them, and I treated their feedback very seriously. One of the techniques that I used to make eev more accessible to them is described in this video, http://angg.twu.net/find-elisp-intro.html (find-1stclassvideo-links "2022findelispintro") (find-2022findelispintrovideo "14:36") from 14:36 onwards - "put several similar examples close to one another, starting by the most basic ones". I treated that technique as "obvious" for many years - I just used it in many places, and I thought that the users would notice that pattern, and start to use it in their own notes. That didn't work, and I saw that I had to spell out that technique explicitly, and repeat it often. When I asked you questions about how to create eev-style sexps that would behave as hyperbole-style buttons, in some of the e-mails that I point to here, http://angg.twu.net/hyperbole.html I was signaling that my mental buffers were almost full... at that point explanations in English helped me very little, and I was trying to write "several similar examples close to one another, starting by the most basic ones" to factor your code conceptually via tests. I _still_ think that your buttons and menus are hacker-unfriendly. The source code is available, yes, but I spent several evenings trying to understand them in my "non-user" way, and I got a mental buffer overflow instead of enlightenment... and I also spent many hours writing e-mails to the Hyperbole mailing list, but the answers left me very frustrated. Hope that helps, =/ Eduardo Ochs http://angg.twu.net/#eev
Org, Hyperbole, and eev
Hi all, this message is slightly off-topic, and a shameless plug... Eev can do many things that Org and Hyperbole and do, but it makes very little sense to people who can play the role of "users" well, in the sense of people who can "use" Emacs packages without looking at the elisp source and hacking it, i.e.: reading the source of the package, inspecting and understanding its data structures, and creating sexps that call the package's functions directly... Eev still has a couple of parts whose data structures are hard to inspect. I don't regard these parts as "real" bugs, but I do regard them as hugely embarassing - and I have just fixed one of them: `find-here-links', that is explained in this section of the main tutorial, http://angg.twu.net/eev-intros/find-eev-quick-intro.html#4.1 and in this other tutorial: http://angg.twu.net/eev-intros/find-here-links-intro.html The way to run `find-here-links' in debug mode is explained here, http://angg.twu.net/eev-current/eev-hlinks.el.html in the second part of the " Commentary:" at the top - look for "Debug mode". As I mentioned in the other thread https://lists.gnu.org/archive/html/emacs-orgmode/2022-06/msg00524.html https://lists.gnu.org/archive/html/emacs-orgmode/2022-06/threads.html#00524 and in these pages, http://angg.twu.net/2021-org-for-non-users.html http://angg.twu.net/find-elisp-intro.html http://angg.twu.net/eev-wconfig.html http://angg.twu.net/hyperbole.html I find Org and Hyperbole difficult mainly because they are hacker-unfriendly. It _may be_ that some of the people who said that they find Org very hard in this thread https://lists.gnu.org/archive/html/emacs-devel/2022-06/threads.html#00186 would also benefit from a bit more of hacker-friendliness... and so it would be great if more ideas could flow between Org, eev, and Hyperbole.

Hi Robert,
can you show us a sexp that will disable Hyperbole completely, and
that we can execute with our favorite variants of `C-x C-e'?
I know that this page
(info "(hyperbole)Default Hyperbole Bindings")
has this paragraph,
{C-h h}
{C-h h X}
Hyperbole Mini Menu: Enable Hyperbole minor mode and invoke the
Hyperbole minibuffer menu, giving access to many Hyperbole
commands. This is bound globally. Use {C-h h X} to close the
Hyperbole minibuffer menu and disable Hyperbole minor mode.
and apparently these sexps toggle Hyperbole minor mode,
(hyperbole-mode 1)
(hyperbole-mode 0)
but even when I toggle it off the global binding for `C-h h' remains
active...
Thanks in advance.
My notes on Hyperbole are here,

Hi Russell,
Some years ago I tried to integrate Hyperbole and eev and 1) I failed
miserably, and 2) I ended up with the impression that Hyperbole is
meant to be "used", not to be "hacked"... for example, in Hyperbole
the action of a button like this,
{C-h h d a}
is to emulate what happens when the user types `C-h h d a'. This
button works exactly as expected; eev implements something similar,
but in a very simplistic, and slightly buggy, way: when we run this in
eev
(eek "C-h h d a")
it simply runs this,
(execute-kbd-macro (read-kbd-macro "C-h h d a"))
that just inserts an "a". The details are here, in the second part,
after the blank lines:
https://lists.gnu.org/archive/html/hyperbole-users/2020-09/msg00013.html
Hyperbole has some amazing features, but its code needs to be
refactored to make more parts of it easier to use from Lisp... someone
needs to do that, and this someone won't be me, as I'm burnt out. =(

Let me suppose that what you mean by your comments is this: "I've spent N minutes watching this video - for N big - and I feel that I've learned very little! What is the best way to learn a lot of eev in M minutes, for M very small?" then the answer is: follow the main tutorial, that is here: http://angg.twu.net/eev-intros/find-eev-quick-intro.html Let me just stress some points that are not obvious at all. 0) You can turn eev-mode on and off with M-x eev-mode. The technical details are here: http://angg.twu.net/eev-intros/find-eev-intro.html#1 (find-eev-intro "1. `eev-mode'") 1) Following a link to a video for which we have a local copy usually takes about three seconds. _For me_ this means that I can use links to videos as links to _images_. You complained that this entry in an index makes no sense: (find-2022eevwconfigvideo "15:50" "6.1, 6.2, 6.3, 6.4") When I execute it with `M-e' it shows - in just three seconds - a page of text with lots of things, and the comment "6.1, 6.2, 6.3, 6.4" in the sexp hyperlink indicates that the most important things in that page of text are the items 6.1 to 6.4. 2) The main principle of eev is "take executable notes of everything that you do". The easiest part of "take executable notes" is "copy to your notes all the links that you find interesting". So, if you stumble on a link to a position in a video that looks slightly interesting, copy it to your notes; if you find a link in, say, this tutorial, (find-emacs-keys-intro) (eek "M-2 M-j") that looks interesting, copy it to your notes. 3) There are ways to create index to videos in Org, but few people use them. Years ago I tried to learn this, but I gave up after a while: https://lists.gnu.org/archive/html/emacs-orgmode/2020-01/msg7.html Also, the organizers of the last EmacsConf were using some tools - that i also didn't learn - the create indexes and transcripts for the videos of the conference. Anyway, tomorrow I will meet with a group of three or four students that are interested in learning Emacs and eev. They use Windows and they have never used Emacs before, so we probably won't be able to do much of this exercise: http://angg.twu.net/eev-wconfig.html#learn-org ...which means: sorry for the off-topic-ish e-mails that were about eev and not about Org, but I hope that we will reach the part in which they'll start to index Rainer Koenig's videos in a few days...

Hi all, I made a video that is mainly for people who are new to Emacs and who are using M$ Windows, and it ends with an exercise that is roughly this: "...now download a .zip file with Rainer Koenig's videos from <http://angg.twu.net/eev-wconfig.html#learn-org>, unpack it somewhere, and use eev to create an index of the video that you've watched, with pointers to the parts that you will need to re-watch many times"... The best way to watch the video is to download it and its subtitles by doing this: wget http://angg.twu.net/eev-videos/2022-eev-wconfig.mp4 wget http://angg.twu.net/eev-videos/2022-eev-wconfig.vtt and then watch the local copy with a video player. The second best way to watch it is to access its index, here, http://angg.twu.net/.emacs.videos.html#2022eevwconfig and click on the timestamps of the parts that look interesting to play the video on Youtube starting from that position. The page about the video and all the ideas behind it is this one: http://angg.twu.net/eev-wconfig.html All feedback welcome! Cheers, Eduardo Ochs http://angg.twu.net/#eev

I was expecting an answer like this: That's difficult to do, but the temporary buffer is generated by the function `org-foo-bar'... you can try to make a copy of `org-foo-bar' called `org-foo-bar-hacked-version', add your own debugging functions to that copy - suggestion: the lines 42 and 99 are good places for that - and then you can change the function `org-plic-ploc', that is called by `org-export-dispatch', to make it call `org-foo-bar-hacked-version' instead of `org-foo-bar'... One possible meaning of "you cannot" is: Org is NOT MEANT to be explored in that way, and this "is not meant to" is in a very strong sense. The last time that a person gave technical information of that kind in the mailing list was 4 or 5 years ago, and we banished her from the community and excommunicated her. Her name shall not be mentioned. Frustrated cheers =(, Eduardo Ochs http://angg.twu.net/#eev
Org for non-users, part 2: `C-c C-e', a.k.a. `org-export-dispatch'
Hi all, a few weeks ago I recorded a video called "Org for non-users" - link: http://angg.twu.net/2021-org-for-non-users.html that was about a way to understand some of the data structures that are used in the support for code blocks. Now I would like to do something similar with the exporter, but I am stuck at the first step... When I run `M-x org-export-dispatch' or `C-c C-e' it creates a second window whose mode line says "*Org Export Dispatcher*" - My first question is: What are the recommended ways to abort org-export-dispatch without letting it destroy the "*Org Export Dispatcher*" window and its buffer? I will probably get stuck at other points later, but I think that I'll be able to get quite far by myself if I can inspect that buffer with the tools that I know. All suggestions are welcome, including suggestions related to questions that you guess that I will have later. =) Thanks in advance!

Re: Video: Org for Non-Users
Hi Samuel,
I know Rainer König's videos! They are fantastic, and I have even
indexed a few of the ones that I've watched several times... see:
http://angg.twu.net/e/org.e.html#rainer-koenig
The indexing above was done with eev's tricks. I have tried to learn
how to do links to positions in videos with Org, but all my attempts
have failed miserably...

Video: Org for Non-Users
Hi all, A few months ago I finally understood why I have always found Org so difficult to learn, and I started to work on a way to use eev - a package that I wrote - to create notes on Org that would complement the official docs "exactly in the way that I needed". I recorded a video about that, and it is here: http://angg.twu.net/2021-org-for-non-users.html TL;DR: I discovered that I am a "non-user" and recorded a video on how I am now documenting Org for "non-users" like me. Initially I am writing the docs in that format for myself, but I hope that they will inspire other people... Cheers, Eduardo Ochs http://angg.twu.net/#eev

Looking for extensions of [[file:~/xx.org::My Target]]
Hi people, this node of the Org manual (info "(org)Search Options") http://www.gnu.org/software/emacs/manual/html_node/org/Search-Options.html explains that we can use links like this one [[file:~/xx.org::My Target]] to point to a string like "<>" in the file ~/xx.org. Where can I find extensions of that syntax that allow using several "projects"? I am thinking of something like this: after telling the extension that in the local filesystem the project "dn6" is at ~/LATEX/dednat6/, and the project "edrxrepl" is at ~/edrxrepl/ then the links [[file:dn6/stacks.lua:Stack-tests]] and [[file:edrxrepl/edrxpcall.lua:Class]] would point to: the string "<>" in ~/LATEX/dednat6/stacks.lua and the string "<>" in ~/edrxrepl/edrxpcall.lua, and I imagine that every such extension would also allow telling the HTML exporter where these "projects" are in the web... Thanks in advance! Eduardo Ochs http://angg.twu.net/#eev P.S.: I still know far less Org than I should, but I am trying to remedy this...

Hi Karl, I was at the EmacsConf2021, but I was totally exhausted due to other chores and spoke to very few people there... I think that your work is VERY important. I am one of the people who have tried to learn Org lots of times and got stuck the same number of times, and any initiative that splits the features - either syntactic or semantics - into layers of different complexity and importance will help me very much. My suggestion about the name is: it's your project, changing its name is not a trivial task, and the people who complained about the name did not offer help. If I were you would simply put "find a better name for the project and change its name to it" in my TODO list as a low-priority task.

Short videos about workflows - and how to upload them
Hi list, this is slightly off-topic - but only slightly, I think. Yesterday I attended (as a lurker...) this meeting of the EmacsNYC group: https://emacsnyc.org/2020/12/28/online-meetup-discussionhow-do-we-improve-emacs.html In it Sacha Chua said that she feels that most people, especially newbies, have a hard time figuring out other people's workflows, and that we should try to make short videos about our workflows and share them... Long story short: I have a nice workflow for recording and uploading short videos to my home page, and I made a 5-minute video about it. It is here: http://angg.twu.net/eev-videos/2020-short-find-ssr-links-2.mp4 It uses eev, that can be used in conjunction with Org, but that is based on design decisions that are very different from the ones in Org. I gave a presentation about these design decisions at the last EmacsConf: http://angg.twu.net/emacsconf2020.html I know only a handful of features of Org at the moment, and I don't know (yet) how to translate the ideas of this method for uploading videos to "pure Org", i.e., to Org without eev... I hope that someone would find a way, and would share it with everybody. Also, I think that it would be really, really, really great if more people start to make their videos downloadable from places that are not Youtube; eev has some functions that help downloading videos from Youtube with youtube-dl - see: http://angg.twu.net/2020-some-template-based.html http://www.youtube.com/watch?v=91-9YfRPsuk#t=19m23s (intro) http://www.youtube.com/watch?v=91-9YfRPsuk#t=22m48s (demo) but they're a bit clumsy... eev also has functions for accessing videos at <http://angg.twu.net/eev-videos/>, and, far more important than that, it has this comment in its source: ;; The definitions of `find-eevvideo-links' and `code-eevvideo' above ;; have strings like "eev" and "http://angg.twu.net/eev-videos/"; ;; hardcoded in several places... it is easy, but not entirely ;; trivial, to create variants of them that point to other sites that ;; stores video tutorials and presentations in ways that are easy to ;; download. If you are aware of sites like that, please get in touch ;; and I'll create functions pointing to them!

Re: Add a new link type for video files
Hi Stardiviner,
just some quick comments on org-video-link-open...
Eev also has functions for opening audio/video files at certain time
offsets. They are called like this (with `C-e C-x C-e' or something
equivalent),
(find-video "~/eev-videos/Punch_and_Judy_Mark_Poulton-K6LmZ0A1s9U.mp4")
(find-video "~/eev-videos/Punch_and_Judy_Mark_Poulton-K6LmZ0A1s9U.mp4" "1:17")
and the sexps above pass these lists to start-process:
("mpv" "~/eev-videos/Punch_and_Judy_Mark_Poulton-K6LmZ0A1s9U.mp4"
"--fs" "--osd-level=2")
("mpv" "~/eev-videos/Punch_and_Judy_Mark_Poulton-K6LmZ0A1s9U.mp4"
"--start" "1:17"
"--fs" "--osd-level=2")
I use mpv instead of mplayer because this page at the Wikipedia
convinced me to:
https://en.wikipedia.org/wiki/Mpv_(media_player)
"--fs" means "full screen" and "--osd-level=2" shows the current time.
If you know other emacs packages that implement opening audio or video
files and skipping to a certain position please tell me - I would like
to mention them in the comments of eev-audiovideo.el. I mentioned your
previous message there, by the way! See:
https://github.com/edrx/eev/blob/UTF-8/eev-audiovideo.el#L55

Changing the Python source block to #+BEGIN_SRC python :output results def square (x): return x*x print(square(5)) #+END_SRC didn't change anything here, neither with emacs24 nor with git emacs, and I grepped (recursively) for ":output" in the directory where I cloned https://code.orgmode.org/bzg/org-mode.git and only found references to ":output-dir" - except for a single occurrence of ":output" in contrib/lisp/ob-sclang.el...

Using Org and eev together - problem with source blocks
Hi list, I gave a presentation about eev at the EmacsConf a few days ago, and after the conference I started to work on a tutorial to explain how to use Org and eev together... links: http://angg.twu.net/emacsconf2019.html http://angg.twu.net/LATEX/2019emacsconf-long.pdf (slides) http://www.youtube.com/watch?v=86yiRG8YJD0&t=774 (demo) http://www.youtube.com/watch?v=86yiRG8YJD0&t=956 (demo: eepitch) http://angg.twu.net/eev-intros/find-org-intro.html (eev+Org, html) http://angg.twu.net/eev-intros/find-org-intro (eev+Org, src) https://lists.gnu.org/archive/html/emacs-orgmode/2013-11/msg00124.html I am longtime Org user that only uses a few features of Org - mainly the ones here, (info "(org)Document Structure") and when I tried to explain in my tutorial how to execute org source blocks I stumbled on a behavior that I found very puzzling... I will copy the relevant code here. The section on preparation says to run these sexps, (require 'org) (require 'ob-sh) ;; or: (require 'ob-shell) (require 'ob-python) and then a bit later the tutorial has this: # (info "(org)Working With Source Code") # (info "(org)Evaluating code blocks") #+BEGIN_SRC sh seq 200 204 #+END_SRC #+BEGIN_SRC python def square (x): return x*x print(square(5)) #+END_SRC but when I run the shell block with C-c C-c I get these errors Error reading results: (user-error No table at point) Code block produced no output. and an empty "#+RESULTS:" block in Emacs24, and the right results block in some later versions of Emacs, and when I run the Python block with C-c C-c I always get a results block like this (without the indentation): #+RESULTS: : None What am I doing wrong? I expected an output of "25"... =( Thanks in advance! Eduardo Ochs http://angg.twu.net/#eev
Re: [O] How to execute org babel src block line by line?
Hi Xor3,
Maybe you should take a look at eev - more specifically, at eepitch,
which is one of its modules... there's a demo here, starting at 0:16,
http://angg.twu.net/eev-videos/video4-eepitch.mp4
http://www.youtube.com/watch?v=Lj_zKC5BR64
and there's a tutorial here:
http://angg.twu.net/eev-intros/find-eev-quick-intro.html
I am not sure if it is already as compatible with Org as it should - I
use Org all the time, but just a few basic features... if you want to
try it and stumble on any problems please let me know and I will fix
everything ASAP - I am in the middle of my holidays. =)
Cheers!

Hi Eric,
I tested your example - with `C-c C-e l o' to export to LaTeX and open
the PDF file -, and the ellipse in the middle of the sentence appeared,
but the block
#+begin_src latex :results latex raw :exports results
\begin{tikzpicture}
\node[red!50!black] (a) {A};
\node (b) [right of=a] {B};
\draw[->] (a) -- (b);
\end{tikzpicture}
#+end_src
did not make its way to the t.tex file... I asked for help in the
#org-mode channel at freenode, as I am an Org newbie, and found a fix.
Your example is one of the best one I've seen so far of diagrams-
in-Org-for-newbies, but it seems to be at least one micro-bug from
perfect, as it supposes that the person trying it has already enabled
latex support in babel!
Here is an idea to make your example more newbie-friendly: add the
comments below to it.
# Note that you may have to add latex support to babel
# to make the tikzpicture block work...
# see: (info "(org)Languages")
# try: (org-babel-do-load-languages 'org-babel-load-languages '((latex . t)))
#
# To disable to question "Evaluate this latex code block on your system?",
# see: (info "(org)Code evaluation security")
# try: (setq org-confirm-babel-evaluate nil)

Re: [O] Moving my init.el to Org
Hi all, I hope you don't mind me jumping into this thread to ask an org-beginner question... My .emacs is about 15000 lines long, and that's fine for me because I have "anchors" at some points of it, and an index at the top, and convenient ways to jump quickly to any anchors. If anyone is curious, here are some links - my package that implements those things is called eev. http://angg.twu.net/.emacs.html http://angg.twu.net/eev-intros/find-eval-intro.html http://angg.twu.net/eev-intros/find-anchors-intro.html http://angg.twu.net/#eev I know that Org implements something similar to that, but I don't know how to use it. This sexp, when executed, (find-angg ".emacs" "unquote-printable") Jumps to the first occurrence of the string "<>" in my ~/.emacs - in the htmlized version, the target of that sexp is: http://angg.twu.net/.emacs.html#unquote-printable So, questions: 1) what is the user-ish way to create a link in Org to the first occurrence of the string "<>" in ~/.emacs? 2) I know that Org lets users implement new kinds of hyperlinks. If the syntax for doing what I asked in (1) is too clumsy, how do we implement a better syntax? 3) The (find-angg ".emacs" "unquote-printable") calls my functions to visit a file and jump to a position. How can I jump to that position using Org's functions *from Lisp*? Or, better, how do we write sexps to expose what Org does? My guess is that that would be done be several sexps, more or less like this pseudocode: (org-hyperlink-method-and-args "file:///~/.emacs#<>") ;; --> (file-and-anchor "~/.emacs" "<>") (org-hyperlink-do 'file-and-anchor "~/.emacs" "<>") Thanks in advance! =) Eduardo Ochs eduardoo...@gmail.com http://angg.twu.net/#eev On Fri, Sep 5, 2014 at 11:49 PM, Thorsten Jolitz wrote: > Marcin Borkowski writes: > >> Hi, >> >> and thanks for all the great replies! >> >> I ended up using orgstruct mode, which is probably the simplest one, >> and (AFAIU) it will enable me to switch easily to outshine if (when?) >> orgstruct is not enough for me. >> >> And now there's another problem: I'd like to have my init file >> collapsed to only headlines on opening.

Now there is an easier way to create what I call "eepitch blocks", which are the things like these: * (eepitch-foobar) * (eepitch-kill) * (eepitch-foobar) The "easier way" is to create an eepitch block for "foobar" as above is to type "foobar" in a line and then type M-T (meta-shift-t). Note that all these things are explained here, (find-eepitch-intro) http://angg.twu.net/eev-intros/find-eepitch-intro.html and that we should definitely create a sandboxed tutorial like that for using eev with Org... I'm saying "we" just because I'll need help with (at least) some details! About ignoring the "#+" lines: this can be done by changing eepitch-comment-regexp, but there a default way that already works, which is to skip the "#+" lines with instead of typing on them...

How can I help? I still know far less about org-mode than I would like to - maybe because I have been using Emacs in a very idiosyncratic way for ages 8-\ - but it seems trivial to create code blocks that can be executed by both org and eev. Here is a example - just replace each "*" below with a real char 15. 1. Execute the code block below with org's `C-c C-c': * (eepitch-shell) * (eepitch-kill) * (eepitch-shell) #+begin_src sh rm -Rv /tmp/eev/ mkdir /tmp/eev/ cd /tmp/eev/ wget http://angg.twu.net/eev-current/eev2.tgz tar -xvzf eev2.tgz #+end_src ;; 2. Eval this to activate eev-mode: (progn (add-to-list 'load-path "/tmp/eev/") (require 'eev2-all) (eev-mode 1)) ;; 3. Now the "char 15"s will be displayed as red star glyphs, and the ;; code block above can be executed both with org's `C-c C-c' and with ;; eev's .

It would be trivial to add to this tutorial - or to some other - the code to download it and to make mplayer play it from given positions... http://angg.twu.net/eev-intros/find-videos-intro.html http://angg.twu.net/eev-intros/find-audiovideo-intro.html and integrating into Org the feature described there - namely: with a certain minor mode activated `M-p' opens the current default video at the first time offset of the current line - should be little more than a 10-line hack...

Re: [O] Connect to the ssh and execute any command
Hi Andrey,
you can use eev - take a look at the demo that starts at 0:18 in this
video here:
http://www.youtube.com/watch?v=Lj_zKC5BR64
http://angg.twu.net/eev-videos/video4-eepitch.mp4
There are many things that I do in the server that hosts my home page
by using this to set up a connection,
(eepitch-do "ssh e...@angg.twu.net")
and then typing on each line that needs to be sent.
If you have any difficulty in setting things up feel free to get in
touch by e-mail, IRC (#eev at Freenode) or gmail chat - there are some
new features that do not appear in videos yet (the videos I have are a
few months old), and I am just resurecting my screencast-making
scripts to make some new ones... and I am exactly at the point where
tests and feedback can clarify a lot my ideas about the best ways to
present things.
Cheers! =)

[O] Quick and dirty code blocks: eepitch
Hello list, I just discovered org-babel-screen... I haven't done my org-homework yet, but I can't resist making an announcement: the package eepitch.el, at http://angg.twu.net/eev-current/eepitch.el.html http://angg.twu.net/eev-current/eepitch.el http://angg.twu.net/eev-current/eepitch.readme.html has some goals in common with org-babel - eepitch also lets us script external programs from Emacs - but it does that in a very different style from org. In eepitch the emphasys is in the simplicity of the implementation - its core is less than 200 lines, it runs on plain Emacs, it uses only two keybindings, support for a new language can usually be implemented in just one or two lines of Lisp, and "eepitch code blocks" can appear in any file and be used in any mode (by the way, I've been using them in org files for ages). Eepitch's approach has several downsides, of course - one of them is that eepitch code blocks will look UGLY to org users, as I never worked on ways of fontifying them... I will try to implement an org-babel language for eepitch code blocks (this is part of my homework). Oh, by the way: org-babel-screen was inspired by the ancestor of eepitch... http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-screen.html http://angg.twu.net/eev-current/anim/channels.anim.html Cheers, :-) Eduardo Ochs eduardoo...@gmail.com http://angg.twu.net/
[Emacs-orgmode] doing `M-x org-mode' loses point
Hello list, Suppose that I have a file with a structure like this: * an org header (some elisp code) * another org header (more elisp code) * another org header (more elisp code) In a file like that it would be natural to switch between org-mode and emacs-lisp-mode; M-x emacs-lisp-mode works as expected, but when I do M-x org-mode the point moves to the first header line, and that doesn't look like the right thing... One solution that just occurred to me is to have a line like this in each elisp block: ;; (progn (save-excursion (org-mode)) (reveal-post-command)) by executing it with C-x C-e (*) I can switch back to org-mode without losing point... the next obvious steps - binding that to a key, patching org-mode, etc, are not relevant here, so I won't talk about them... So, is this org-mode-jumps-to-the-first-header-line a bug or a feature? Is there a standard workaround? Thanks in advance, cheers, Eduardo Ochs http://angg.twu.net/ [EMAIL PROTECTED] (*): We need this: (autoload 'reveal-post-command "reveal")) ___ Emacs-orgmode mailing list Emacs-orgmode@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-orgmode
