[BUG] commit 7048876f broke Figure link with caption [9.6 (release_9.6 @ /Users/powellb/src/org-mode/lisp/)]

[Brian Powell]

It seems that the following commit broke the ability to link to a figure
with a caption.

  commit 7048876f6fa519513763c83bc5baa791420cddab
  Author: Ihor Radchenko 
  Date:   Tue Dec 13 11:44:22 2022 +0300

  org-export-get-ordinal: Do not ignore ELEMENT type when TYPES is given

  * lisp/ox.el (org-export-get-ordinal): Append ELEMENT type to TYPES,
  when TYPES is non-nil.

I have a simple file with a figure and image link. The figure has a
#+name and #+caption. If I add a link to the figure name in the
document, then exporting to HTML fails. Prior commits did not have any issue.

Using `emacs -Q` with the following:

(add-to-list 'load-path "/Users/powellb/src/org-mode/lisp")
(require 'org)

With the following sample file:

#+TITLE:   test
#+AUTHOR:  Me
#+EMAIL:   email
#+DATE:


#+name: fig:parcel
#+caption: Illustration of joy
#+attr_html: :width 600px
#+attr_org: :width 50px
#+attr_latex: :width 3.5in
[[file:./test.png]]

Done!

So, Figure [[fig:parcel]] is an illustration of the stuff.

Executing C-c C-e h o : to export to html and open, results in the
attached trace dump.

Cheers,
Brian

[Brian Powell]

Nicolas,

Thank you for the message. I spent about 2 hours on it today learning more 
about lisp and the internals to explain your email to me. I learned a lot.

I have modified ox-html.el to include a local OPTION as well as a customizable 
setting. I tested with both as well as with an export option. All three worked 
correctly. I also updated the org-manual.org.

Please find my patch attached.

Cheers,
Brian

Inconsistent use of \ref and \eqref in ox-latex and ox-html

[Brian Powell]

This topic was discussed in 2015:



However, it seems that it we are still stuck with inconsistent exports between 
latex and HTML.

The issue is that when exporting equation numbers with ox-html, it uses 
MathJax's \eqref that wraps the equation in parentheses, for example:

"Refer to (3) for more."

However, when exporting the same document with ox-latex, it uses Latex's \ref 
that does not wrap the equation in parentheses. Would it be possible to add an 
option or variable to ox-html for the user to select whether to use \ref or 
\eqref on export? 

For those of us that publish to HTML and PDF, it is very difficult because you 
end up with either double or no parentheses.

My proposed fix would be a change to ox-html from:

   (format "\\eqref{%s}"
   (org-export-get-reference destination info))

to

   (format (if org-html-export-mathjax-ref "\\ref{%s}" 
"\\eqref{%s}")
   (org-export-get-reference destination info))

The variable org-html-export-mathjax-ref is non-nil to use \ref vs. nil to be 
the default \eqref.

Brian   

Re: [O] The statement on what is orgmode.

[brian powell]

 6. Org-mode: It's difficult to say what exactly Emacs' Org-mode will
 do for you; it's easier to list all things it doesn't do.

Wow! Great thread.

I was going to ask the question what @isn't@ Emacs OrgMode--and not in a
trite way at all; in a serious way.

Emacs is a mode-less (concurrent major modes and minor modes galore) and an
infinitely extensible software tool.

OrgMode is an amazing tool that enables Emacs users the ability to do a
huge number of things, very simply and easily.

(E)macs (M)akes (A)ll (C)omputing (S)imple.

I often think: What are the epistemological limits of Emacs? What can't
you do or find out in Emacs?

Emacs has the fastest regexp engine (in the NFA and first character
descrimination sense--p.197 MRE, Friedl, et. al) for some things.

OrgMode's table interfaces with EmacsCalc--an extremely high-quality
science and math tool.

Seriously, you can do anything in/with Emacs; and, OrgMode works well in
most all other major modes in Emacs.

Remember the old icon symbol of Emacs--it literally is a picture of
kitchen sink--because you can do everything except the kitchen sink in
Emacs--and therefore OrgMode.

So, again, seriously, this thread is misnamed.  What can't you do in
Emacs/OrgMode?  What can't it be used for?--this should be the thread!

I'd really like to know.  Every week or two, something comes off my very
tiny list, which is just about empty.

Of course we all have computing limits of cpu and hard-drive space etc. so
those hard limits will always be the bottleneck as to what Emacs and
OrgMode can really be used for--buffers can only be so big.

Theoretically there are no limits here except computing limits--P vs. NP
is unproven--but P(space) is a hard limit.

Like with so many other things in life; Emacs OrgMode is what you make of
it.

If I had to chose: I vote for #1 or something like: Its your life
[organized] in plain text.

[O] [OT] Mindwave Emacs. EEG reading and Data gathering in an org-mode buffer.

[brian powell]

 I still wonder if org is the right medium for this. Most of the
 devices are going to give you a TON of data (the neurosky raw stream
 is ~500hz update, emotiv is ~128hz, etc...). Pedometers and blood
 pressure monitors that do one-time large dumps might be somewhat more
 feasible.



* EMACS OrgMode is one of the right mediums for this:

** can put massive amounts of data in a tiny icon on your screen (that you
can wave your mouse over to glimpse whats inside--which could be data or
notes, etc.

** can quickly fold and unfold the data in a tree-like structure.

* I used to work with brainwave data with EMACS and neuroscientists at NIH
would be amazed at what I could do with the data.

* EMACS is in MIT's top 20 of all-time developments in Artificial
Intelligence.

You can use EMACS to massage the data and EMACS OrgMode to study whats
interesting to you and/or present it to other researchers.

Re: [O] [OT] Mindwave Emacs. EEG reading and Data gathering in an org-mode buffer.

[brian powell]

* If you're worried about a TON of data filling the emacs buffer then
expand the max buffer size or you might want to look into QEmacs by Fabrice
Bellard (of Pi calculation fame, and creator of QEMU)

** I've used QEmacs to edit gigabyte+ size files.

*** I'm not sure that's what you're worried about; but, whatever.

Re: [O] [OT] Mindwave Emacs. EEG reading and Data gathering in an org-mode buffer.

[brian powell]

I used to do brainwave research (using eeg's): Maybe make some software
(R?) to do some FFT (Fast Fourier Transforms) calcs on the brainwaves and
compute the power wave and have it report percentages or counts of
AlphaWaves, BetaWaves, ThetaWaves, etc?

Thanks Jonathan and Joakim (zen-mode) for the software!

  Hi Orgers!
 
  I recently picked up a Neruosky Mindwave, a consumer level EEG device (it
  reads brainwaves).  Unfortunately, the software bundle doesn't include a
  way to log the EEG levels.  Since I am fairly decent at Elisp, I thought
 I
  would write a little library to interface with the mindwave, and store
 the
  results.  Naturally I thought of using an org-mode buffer for this.
 
  So I present, mindwave-emacs:
 
 https://raw.github.com/jonnay/emagicians-starter-kit/master/extra/mindwave-emacs.org
 
  Mindwave-emacs.el really is just a low-level interface for emacs.  Inside
  of the org file are 2 examples (actually, fully working programs) that
  show you how to work with it.
 
- gather-into-org.el :: allows you to write data into an org-mode file
- solarized-mind.el  :: uses the eSense Attention and Meditation
  measurements to provide feedback to the user on their brian state.
 
  I am also working on a lower-level serial/binary connection to retrieve
  data from the mindwave to help facilitate raw EEG logging.
 
  I don't know if this is going to be useful to anyone, but I figured some
  people may be interested.

 Cool!

 I did some Neurosky Mindset integration for my zen.el package:

 Maybe I can integrate your package and mine, I'll have a look!

Re: [O] [OT] Current website not very attractive

* The site looks great as it is.

** Its supposed to be simple and simple-looking:

*** Go to: http://orgmode.org =

Read the top line: Org: Your Life in Plain Text

*** Go to: http://doc.norang.ca/org-mode.html =

Read the top line: Org Mode - Organize Your Life In Plain Text!

* Simplicity and portability is a huge part of the point of OrgMode right!?

* EMACS and TeX and Texinfo, etc. are great (partially) because they have
been ported to all platforms.

** So, if you make any changes, you should be able to convert the end
webpages to Texinfo
so they are readable and printable on all computers and printers.

 I'd like to be able to set the line-spacing such that there is a nice
 visible vertical gap where I've actually hit the carriage return to create
 a new paragraph and a smaller vertical spacing where visual line mode has
 emulated a carriage return for readability. This would probably help in my

 They are already in a file: the org file that contains the link.
 A link like this  [[file:foo.txt][foo]] pops up a LINK: file:foo.txt
 balloon, so a suitable grep/sed combination suffices.

 But I suspect that this is not a satisfactory answer: what exactly are

* Fully agree with nick--especially about the please be more specific
about the MUA-part--mh-e is another possibility--written by another

another person I used to work with...

** Come to think of it; I used to use RMAIL too in EMACS--Kyle wrote
VM to include MIME/mail extensions, etc.

 You mentioned that you tried GNUS as a mail reader, etc.--and you
didn't get what you wanted:

= In a nutshell: MH/mh-e is the quintessential all-in-one extremely
customizable mail package and mh-e is the EMACS mode for
it--absolutely amazing and useful for email (written by
W3Org/consortium people I used to work with)--probably overkill for
you. RMAIL is old, slightly outdated--but very useful and simple, VM,
is better for you probably: This site/guru agrees with me--VM is your
best choice:

Emacs has three built-in mail reading and sending interfaces:
RMAIL
RMAIL is a basic (and the default) mail reading package.
MH-E
MH-E is a front-end for the MH mail tools.
Gnus
Gnus is mainly a Usenet reading package but has capabilities for
reading mail and doing other strange things.
Now that you know your options inherent in Emacs I'm going to tell you
about my favorite non-standard mail user agent (MUA): VM (View Mail)
written by Kyle Jones.

 Are you using an emacs package to send email? Or are you just composing
 your email in emacs, saving it as a file and sending it with some
 external MUA?

 If the former, you can probably find a hook that the emacs package uses
 (e.g. for mh-e, the appropriate hook would probably be
 mh-before-send-letter-hook), so that you can save the email in a file,
 possibly after transforming it suitably.

 In some sense this is similar, but in another sense opposite, to Jos'h
 Fuller's suggestion: in his scenario, you use org-capture to compose the
 message and use an org-capture hook to transform it suitably and
 actually send it; in this scenario, you compose the mail in some mail
 package (there are several) and you use a hook that the mail package
 provides to transform it suitably and save it in some org file.

 OTOH, if you use an external MUA, Jos'h 's approach might still work
 whereas this one has no hope. But if you can live in emacs, why live
 anywhere else? :-)

I will be teaching singing to a mixed group using a projector.  Those who
can read sanskrit would be put off by the roman (English) and those who
cant of course need the roman.
The attached screenshot shows two emacs buffers side-by-side with the two
versions.

I am now exploring the possibilities of how to make a 'presentation'
putting the two together.
I am not too comfortable using emacs for the final show because emacs
occasionally crashes -- due to non-standard fonts, input methods or what I
dont know -- and I dont want this to happen in front of 50 people!

Any thoughts/suggestions?

** Ideas: I strongly suggest EMACS and learn how to use EDIFF in EMACS--its
the best envirionment for translations and what you want to do--don't toss
out EMACS because it crashed once: suggest you test it before the
demo/presentation sing-along.
*** How to stop it from crashing: Use only what is necessary to show your
SANSKRIT and ENGLISH buffer: Do something like:
Make 2 files with line numbers at the begin of each line:
nl sanskrit-song.txt  sanskrit-song_line-numbers-at-front.txt
nl english-song.txt  english-song_line-numbers-at-front.txt
emacs -q -l
sanskit-blah-mule-multilingual-emacs-programs-needed-to-show-sanskrit.el
 sanskrit-song_line-numbers-at-front.txt english-song_line-numbers-at-front.txt
Mx ediff-buffers
Emacs will pop-up an ediff window--put your mouse cursor on it and tap
?--it will show you the ediff keys--n for next different line will be
most helpful
(ediff will ask for the 1st and 2nd buffer you want to compare--type
in sanskrit-song_line-numbers-at-front.txt
and english-song_line-numbers-at-front.txt

--then tapping n (with your cursor on the popped up ediff window) goes
line-by-songline in both buffers--highlighting the text for a sanskrit

Re: [O] Images in Tables?

 Hello!

 I was wondering if there is any useful way, to organize images in
 tables. This would be useful e.g. if one needs to organize some images
 on a regular grid, but the images aren't equally sized, such that a
 simple line break doesn't do the trick.

 Creating just a table with the image links inside will work
 /basically/, assuming that the images have an appropriate size, but if
 resizing is needed, I can't see how to do this in a table (because
 inside no e.g.  #+ATTR_LATEX line is possible).

 The same problem also occurs when I want to preview images side-by-side,
 e.g.

  :  [[./img1.png]] [[./img2.png]]

 though here actually newlines from fill-paragraph/auto-fill add to the
 problem - as will be the size of some high-resolution images.

 My only current solution is to use explicit LaTeX and then preview the
 LaTeX, but that slows down operation considerably.

 Is anything currently implemented to allow such usage?

Re: [O] Org mode, minted, and non-ASCII

[brian powell]

* Firstly, thanks for sending this issue to the group: pygments  minted
are very interesting tools for OrgMode/LaTeX persons.

** Read this
http://ctan.mackichan.com/macros/latex/contrib/minted/minted.pdf

** And this: http://pygments.org/docs/unicode/

*** Seems that running the pygmetize from the command line has some
provisos.

*** Also, noticed this in bold type at
http://pygments.org/docs/unicodethat might help you:

Since Pygments 0.6, all lexers use unicode strings internally. Because of
that you might encounter the occasional UnicodeDecodeError if you pass
strings with the wrong encoding.
...
The formatters now send Unicode objects to the stream if you don't set the
output encoding. You can do so by passing the formatters an encoding option:
from pygments.formatters import HtmlFormatter
f = HtmlFormatter(encoding='utf-8')
You will have to set this option if you have non-ASCII characters in the
source and the output stream does not accept Unicode written to it! This is
the case for all regular files and for terminals.

Subject: [O] Org mode, minted, and non-ASCII
To: emacs-orgmode@gnu.org

Hi, Org people.

Still experimenting around for this report, I installed *minted* so one
of the appendices might nicely display a bulky bit of Python code.

It works satisfactorily (and speedily enough) if I squash out all
diacriticized and other Unicode special symbols in the file.  However,
no output is produced if I leave the tiniest non-ASCII character in the
file.  OK, OK, don't kill me :-).  Agreed that all non-ASCII characters
are neither tinier or bigger than one another in this context.

The Org document, the Python sources, and the default charset for this
machine are all UTF-8.  I saw no Unicode problem between Unicode and
LaTeX when minted is not in the picture.  pygmentize also appears to do
well with Unicode input.

So the problem likely lies either between Org mode and minted LaTex, or
within minted.  Is that a known problem or limitation?

This problem is bit more hurtful here, as the Python code really uses
Unicode, and mangling out Unicode characters really changes the semantic
of the code as displayed in the report.  If it was not for this problem,
the minted output is attractive, at least more than what I saw with the
listings package.  On last resort and of course, I may still include an
unfontified Python source in the appendix, or produce it by other means;
not such a big deal, it's just that I would have liked to impress my
coworkers a bit more with Org mode integration and capabilities.  :-).

To confuse me a little more, I'm getting random (I mean, unpredictable
by me) org-mode fontification error diagnostics while creating the PDF
output.  Perusing org.el tells me that this is likely a mere
coincidence, as those fontification errors seem wholly unrelated to
LaTeX processing.

François

P.S. Who is a bit tired right now, and maybe missing something trivial?
Tomorrow, I'll surely revisit most of today's experiments.

Re: [O] OT: collage of scripts [was: Re: table alignment failed for Asian char

[brian powell]

* One of my favorite Hofstadter books is: Le Ton beau de Marot: In
Praise of the Music of Language (ISBN 0-465-08645-4), published by
Basic Books in 1997, is a book by Douglas Hofstadter in which he
explores the meaning, strengths, failings, and beauty of translation.

** Translation between frames of reference — languages, cultures,
modes of expression, or indeed between one person's thoughts and
another — becomes an element in many of the same concepts Hofstadter
has addressed in prior works, such as reference and self-reference,
structure and function, and artificial intelligence.

** This topic correctly has been labeled OT; but, on the subject of
translation and modes of expression (in the OrgMode table); this is
related to the original thread/topic: table alignment failed for
Asian chars.--getting back there for a moment:

*** Are there any Asian/Chinese/Tamil character sets that have fixed
widths?  Chinese writing is picture writing, where characters
actually represent, to varying degrees, a picture or an abstract
concept of the thing they represent.

 I remember many years ago, suggesting to fellow software
engineers, that they do just that: Make fixed-width Tamil character
sets that will work well in EMACS.

* One possibly simple work-around (not sure this is what you seek):
Put all your non-fixed width Asian characters into cells like:
[[blahAsianCharactersOrPNGofAsianChars][A]]

** All you'd see is an A and then the table will look covered down
(in an OrgMode buffer)--but you may have to manually adjust the
OrgMode table.

*** Another idea: you just put something like A555 (simple
PlainText--maybe the unicode string equivalent like: U+024B62) in
the table and have a program that replace the PlainText  U+024B62 with
the AsianChars and/or a .PNG picture file link when you click an
icon/run the program.  There are ELISP programs which help with
inserting glyphs that you could use and/or extend this hash array:

 Excerptions from unichars.el:
(defvar unicode-character-list
  '(
;Codept   Unicode nameISO Name
(#x00 NULL   nil )
...
   (#x00fb92 ARABIC LETTER GAF ISOLATED FORMnil )
(#x00fb93 ARABIC LETTER GAF FINAL FORM   nil )
(#x00fb94 ARABIC LETTER GAF INITIAL FORM nil )
(#x00fb95 ARABIC LETTER GAF MEDIAL FORM  nil )
(#x00fb96 ARABIC LETTER GUEH ISOLATED FORM   nil )
...
* See this wonderful extension/new take on this too:
http://proofgeneral.inf.ed.ac.uk/releases/ProofGeneral-3.7/x-symbol/lisp/x-symbol-unichars.el
--so suggest looking at x-symbol-unichars.el, unichars.el and maybe
x-symbol.el and maybe then input UNICODE glyphs into your table.
Can you extend it to Asian/Chinese/Tamil chars?
(I don't see any in the files x-symbol-unichars.el, unichars.el, x-symbol.el)

*** Last idea: I've put ticker-tape .GIF files in EMACS OrgMode
buffers--you could put an infinite scrolling ticker tape of AsianChars
in fixed-width .GIF files with say a 16x16 pixel window (or wider) and
then know a priori that the table would remain covered down--when you
view it in an EMACS OrgMode buffer--regardless of what text you put in
it (This is probably not what you want though--but if you are doing a
presentation or tutorial of some sort and you want to show your table
with scrolling notes in table cells, then it can work for you--I've
done it.)  You can use ImageMagick to create the .GIF files--of the
scrolling Asian text.

Re: [O] Ways to make org feasible for huge files

[brian powell]

* Maybe EMACS  narrowing could be used:
http://www.gnu.org/s/libtool/manual/emacs/Narrowing.html
...
Narrowing can make it easier to concentrate on a single subroutine or
paragraph by eliminating clutter. It can also be used to limit the
range of operation of a replace command or repeating keyboard macro.
...
C-x n n
Narrow down to between point and mark (narrow-to-region).
C-x n w
Widen to make the entire buffer accessible again (widen).
C-x n p
Narrow down to the current page (narrow-to-page).
C-x n d
Narrow down to the current defun (narrow-to-defun).

** I mean: Maybe an OrgMode user could do narrow-to-region (and then
just render on the new smaller region) and/or an implementation
something like org-narrow-to-region could be coded.

*** Just an idea--your mileage may vary--it may not work at all--I
hope you try it out and tell how it works for you.

* I ran into similar problems: I made the file into 2 separate
files--one very large and the other very small that I render a
lot--when it gets big, I just prune out older and less important now
(backburner) subjects, paste them at the bottom of the small file and
then cut and paste the less important * sections into the big file.
** Works great, its really the best way to do it--for backing up and
encrypting reasons and hard drive space reasons etc.
** Could call them blahfile_now.org and blahfile_later.org (for the
small and large files respectively).
*** Since OrgMode files are plain text files, this works great.

Re: [O] TABLES: Remove/add cell

[brian powell]

* May want to turn org-mode/table off temporarily (or maybe it will
just make it easier) then you can do the rectangle edits michael was
referring to:
** Go to the point just to the right of the 4.
** C@ ---marks the point.
** Go to the 3.
** Cxrk
** Go to @2$2--i.e. where the 4 used to be.
** Cxry
* Emacs OrgMode makes all of this easier since it lines everything up
for you by covering down the columns (org-table-align)---making all
the cells easily edited by the usual rectangle-killing and
rectangle-yanking methods.
** The method above can be generalized for editing OrgMode tables
regardless of the number of symbols in the cells--since OrgMode aligns
them for you; and, EMACS is restricted only by the amount of RAM in
your computer.
*** Also, if you want to edit gygabyte size files, using similar
methods, I highly recommend QEMACS.

Re: [O] Lisp nesting exceeds `max-lisp-eval-depth'

[brian powell]

*Variable: max-lisp-eval-depth
This variable defines the maximum depth allowed in calls to eval,
apply, and funcall before an error is signaled (with error message
Lisp nesting exceeds max-lisp-eval-depth). This limit, with the
associated error when it is exceeded, is one way that Lisp avoids
infinite recursion on an ill-defined function.
The depth limit counts internal uses of eval, apply, and funcall, such
as for calling the functions mentioned in Lisp expressions, and
recursive evaluation of function call arguments and function body
forms, as well as explicit calls in Lisp code.

The default value of this variable is 300. If you set it to a value
less than 100, Lisp will reset it to 100 if the given value is
reached. Entry to the Lisp debugger increases the value, if there is
little room left, to make sure the debugger itself has room to
execute.

max-specpdl-size provides another limit on nesting. See section 11.3
Local Variables.

**I think this is one weakness of ELISP vs. CommonLISP--but this is
by design; EMACS has always been focused on editing, so some
trade-offs are used, objects such as buffers, windows, etc. are a
paramount part of the language--and recursion is handled slightly
differently, I believe this is done on purpose.

**Maybe try to set the max-lisp-eval-depth variable higher?

***Maybe something like (setq max-lisp-eval-depth 3000)

**Maybe load the common lisp module; which is always a good idea--but
this probably won't help, just an idea.

  been unable to get it to remind me at all.
 
  Any suggestions?

 I use the growl notification system (on MAC) along with todochiku.el for
 simple timer notification out of Emacs. Growl can be set to 'speak' the
 notification (not sure about other sounds).

 todochiku also works with (snarl/libnotify) on other OSs.

 The command todochiku-message allows you to add a notification to a hook
 such as org-timer-done-hook (in your init file)...

 --8---cut here---start-8---
  (defun mj-notify-timer-done ()
   (todochiku-message Title here Further text here

Re: [O] convert html file into orgmode .org file?

** Install pandoc-mode.el (see

** Goto buffer with .html doc in it.
*** Get OrgMode and PanDocMode running simultaneously in the same buffer.
** Click on the PanDoc menus in EMACS:

*** Chose PanDoc-OutputFormat-OrgMode
*** Chose PanDoc-RunPanDoc

may vary--depends on the structure of the HTML file.

*** Don't believe the idea is that you put in any private information.

* To me I see a free online service that is searchable and one can jot
notes, reminders and/or URL's in--it could be used as a NotePad app

important to me) as a remote SMS messaging service:

** The Future of Thoughtback:
http://blog.thoughtback.com/post/7630178945/the-future-of-thoughtback

Our goal is to help people choose and organize the thoughts they want
to remember. Programming your mind to think and act the way you want
is not only powerful, but exciting. By constantly getting these
“thoughts back”, your mind begins to shape itself differently. These
form your actions, ideas, habits, and choices.

* So what’s the near-future roadmap look like?

An API for developers
SMS (texting) to send/receive thoughts
New settings for getting your thoughts back
Improved iPhone and Mac apps
Beta opt-in program to test new ideas

* What does this have to do with OrgMode!?:

** ThoughtBack sends you random reminders from the thoughts you put in
(I'm thinking GTD)--I'm thinking maybe a mashup with MindMaps and
maybe OrgMode.

* At this point, to me: Its another (minor) tool in the toolbox--its
free, and always-on and available--as long as I have an Internet
connection.

** Its like Twitter I guess; but, it sends thoughts back to you rather
than the millions of Tweeters that probably don't care about how your
cat seems to feel or that you ought to get a new ladder--but to you,
these things may be important.

** This sort of thing, writing down things to do and/or thoughts or
ideas that may be useful in the future is a good thing to do--you can
stop dwelling on it, its often a worthless or obsessive thought but
the act of writing it down somewhere allows the mind to relax on the
subject and get back to what is more important at the time: I learned
this from a book by Tony Buzan: Make the Most of Your Mind (February,
1984) ISBN 0-671-49519-4 

*** http://en.wikipedia.org/wiki/Tony_Buzan : Anthony Tony Peter
Buzan ( /ˈbuːzən/; born 2 June 1942) is an author and educational

** In OrgMode I guess most people put in deadlines and schedules etc.;

thoughts that don't fit any structured category, time-lined project or

 - start to play in file at 00:03:21, stop at 00:06:54:

 - play the whole file:

 I would like to explicitly not allow [[file:some_podcast.mp3::03:21]]

[O] Fwd: Kedit-like ALL command for emacs

[brian powell]

Well, if that is what he wanted; then, suggest one of these:

Mx query-replace

and/or

Mx query-replace-regexp

--EMACS has the best/fastest regexp engine available for doing an

Mx query-replace-regexp

Because ELISP has a lot of functions optimized for editing files,
using multiple buffers, windows, etc.

The regexp engine is optimized for first-character-matching; i.e.
quickly finding and highlighting and replacing characters in a
buffer--faster than anything else, last time I checked.

Suggest using QEMACS if you want to edit multigigabyte files.

Also, to use an occur buffer (which you seem to refer to below) all
you would do there would be:

Mx occur

Then go to the *Occur* buffer where it shows the matching regexp in
highlighted text and then LeftMouse on the line (anywhere on the line)
and the line will pop up in the other window.

Also, there is a way to edit every file in the set of a regexp in a
directory tree (a
top-level directory and all of its subdirectories) that contains a
regexp--one replacement at a time:


** Occur mode changes:

*** The new command `multi-occur' is just like `occur', except it can
search multiple buffers.  There is also a new command
`multi-occur-in-matching-buffers' which allows you to specify the
buffers to search by their filenames or buffer names.  Internally,
Occur mode has been rewritten, and now uses font-lock, among other
changes.

So you could do something like emacs blahfiles* and then:

Mx multi-occur

and/or

Mx multi-occur-in-matching-buffers

 I haven't used KEDIT.

 one can edit the matches and have the replacements propagated to the
 searched buffers.

 But list-matching-lines pops up a read-only buffer. Also the last line
 of the docstring says `In any case the searched buffers are not
 modified'.

 I think OP wanted something where the searched buffers are modified from

SQLite (used in ZOTERO) is a simple/short C program and its (last time

SQLite databases are very easy to work with and are often 1 simple,
small, very portable file.

I was reading some article yesterday: SQLite was ranked #1 in the top
ten best/most useful software of all time.

I understand your concern; and, often an SQL database is overkill and
NOSQL seems in vogue right now--but SQLite is something you might
really like--you can manipulate SQLite databases easily, like
plaintext.

I just tried ZOTERO too--very impressive.  I'm a lot more used to

 Do you have a way to get the sunset located on a line on its own

 line from the sunrise one)?  That'd be even much nicer...

  No, but I would like one:) If there were separate diary functions for
 sunrise and sunset it would be easy. Maybe I need to look at the diary elisp
 and write my own separate functions.

Re: [Orgmode] Re: Can I input multiline in a cell?

[brian powell]

I haven't sent any HTMl that I know of--I fully embrace the plain text
KISS methods.

I've changed my fonts (all fonts--fixed and otherwise) to a font using the
string  Mono  somewhere in its name, and things seem better reading and
copying-and-pasting into an email buffer like this one--it should take care
of all problems with reading and writing @aligned tables@.

Thanks for pointing that out Bastien (about the fonts)--the FreeMono and
Courier fonts in GOOGLE CHROME are ugly--I tried them all after your
email--I settled on DejaVu Sans Mono Book; but, again, I have never posted
HTML to this list that I remember--I used to work with IETF members on XML
protocols and I'm very familiar with GML, SGML, HTML, XML, etc--I know HTML
when I see it.  The only markup that I inserted was [[file: --but thats
not HTML--its OrgMode?

If I paste text and set its font to XYZ @and@ you allow your browser to view
the XYZ font and character set @and@ you have the XYZ font software
installed and/or your email software has it, then you'll see it the way the
writer intended you to see it.  If you ever see anything from me with
uncovered down/aligned table columns again, please tell me, sorry about
that, it shouldn't happen again.  I strongly believe that problem has been
solved.

(I'll look into turning off HTML sending in my GOOGLE CHROME browser
options--like you suggested Bastien)

As for OrgMode and my idea, my plan: I will be setting ^H as an
end-of-line $ marker in my own code--when I am in a buffer running
OrgMode--and I'll see if I can make multivariate stat. tables like the
example table Wang gave--EMACS has the only regexp engine that is easily
tweaked that way--that I know of (see Regular Expressions, O'Reilly, 1st
edition)

Now, should OrgMode table mode support the creation of tables like the one
Wang gave as an example? I think it should.

--But I'm so giddy about OrgMode as it is right now, I almost don't care!

;-)

I have no idea what you mean here--maybe earlier emails? (which I requested
we disregard earlier)

I didn't find the option Bastien was refering to--to turn off the sending of
HTML.

I have been experimenting with sending images in GOOGLE CHROME--maybe that
setting is what you complain about/suffer from?  I do want to continue to do
that; but, what exactly you are complaining about, I don't know?

I sent a very complex set of tables (2 emails ago) and all the tables were
covered down/aligned?

Lastly, please remember this thread purposefully contained markup to
pictures and/or [[file: and other probelematic text like multiline
text (this thread) in OrgMode tables--its all experimental what if
stuff--I purposely tried to insert strange things into the OrgMode table?

It was fun and interesting; and, I learned a few things.  Now, please feel

I'm not offended; I'm looking into the turning off of html from my GOOGLE
CHROME browser.  I have been experimenting with the new features like
inserting images, etc.

And yes, as you point out that very email has markup (on your side--if you
accept it)--and that very email apologized for the problem and explained
that I would look into it--its still a problem--for you.

Everything looks fine to me now--even when I browse the postings.

I know a lot about MIME and browsers believe me, and email systems and
software and the internet...

you can go and learn something about MIME and what mailers do behind your
back.

--much agreed; this will always be an issue when using GMAIL or other
proprietary mail systems.

Thanks for the help Nick.

 I'm not trying to insult/upbraid/shut you up. And I was not

 pointed out that the statement was wrong. That's all.

 You learnt something from earlier emails.  That's good. Maybe you can

in an OrgMode Table.

These intersting work-around-hacks worked for me:

[[file:/blahfilewithyourmultilinetextinit.txt]] ---put this in a org-table

and/or

put a string like:

/blahjpegabsolutepath/blah.jpeg  ---where the jpeg contains a jpeg of your

 You should be able to export this table to HTML or LaTeX and simulate a
 multiline cell on the first column.  Just a workaround, but could do in
 some situations.

 Also, note that you can shrink the cell length by adding length:

 |---+--|   |---+|

Re: [Orgmode] Re: Can I input multiline in a cell?

[brian powell]

They were plain text emails?

(Believe me, I understand what you mean/the problems people cause when they
paste things in the buffer that aren't plain text--that is one reason to use
OrgMode.)

In any case, sorry about that--I just copied-and-pasted my tests--right from
the OrgTable/file?

My suggestion then (after all that brainstorming crap) boils down to this
alone:

Maybe put in 1 key in table mode that puts a dummy line in, maybe something
like this:

|

--it puts in the same number of cell separators and empty cells on empty
line as are on the previous line---or you could just do:

Cu 8 | Enter Tab

And then it spreads it out/covers-down the columns--or the user then just
taps Tab

(OrgMode will then format the table for them)

And then the OrgMode user would type in the multi-line-text column in the
respective column-cells.

Or I suggest a keyboard-macro (to put in the dummy rows) for this too;
thats what I'll do--I'll put it in my .emacs.


Thanks Bastien and Wang.

Bastien: I agree with you, every time I get emails from other users, they

All you have to do is this I believe (not sure about the Org publish/TeX

Re: [Orgmode] org-mode without stars

[brian powell]

The original outline-mode in EMACS which predates org-mode used stars.

Using stars * is the best way to do it; the reasons are many--OrgMode
files are flat text files and this is great too--but keep this in mind
here--think about searches, etc.

PYTHON uses indentation (and thats great); LISP silly/wonderful parens,
etc.--for EMACS use stars!  They look great!  They are the best thing to use
here:

Stars * are also used as the symbol for regular-expressions--based on
neurology/neurons/dendrites/trees/outline-trees/etc. and the Kleene
Closure (i.e. the mathematician Kleene)--the study of neurology and
regular-expressions and the stars * are intertwined--the history dates at
least back to the 1930s--and LISP/lambda calculus/Alonso Church/Kleene--the
1950s.

A star * @is@ a Kleene Closure--math.

A star * is easily recognized as a symbol for a note: From
http://Wiktionary.com:   *== Used at the beginning of a footnote ,
especially if it is the only one on the page, and after a word, phrase, or
sentence that this ...

So, why should I care!? (you might have been thinking)

Well, howsabout this: Say you are searching for a string and/or regular
expression in a flat text file--you wouldn't search for *--you would
usually be search for a string (maybe an indentation level of stars *)
using EMACS--which is by the way the fastest way to find such things --if
you are typing in real-time--emacs will highlight a search as you type
it--this function is very fast--Suggest you try these 2 examples: Cs
blah-search-string ***--and maybe Mx search-for-regexp ***---they have
different uses/meanings--when searching in EMACS) since emacs is the fastest
regular expression engine (for 1st-character(s)-recoginition (the engine is
optimized for this) so for this case/this type of search there is @nothing
faster@ (BTW check out QEMACS if you're working with a huge/gigabyte size
files--its fun to edit huge files with QEMACS--written by the same guy that
calculated PI with a desktop computer--to the longest # he also wrote QEMU
(Fabrice Bellard: http://bellard.org) for this type of regular-expression
search (many other engines are faster and use different algorithms--for the
purposes they were built for--and so they should be used then--each regexp
engine seems to have a niche.)

Use EMACS OrgMode and use stars *, they really are the best for this case;
my brain is overheating thinking of the many good reasons.  But, How do
they look when you print them out!?, etc.; well, I suggest you tailor that
with PERL, thats what I use--I quickly change doc formats to TeX--TeX is the
only thing that @really@ looks pretty!

Please leave well enough alone! That said, I hope you do whatever you want
and don't listen to me or anyone else on such matters--EMACS is infinitely
extensible, have fun!

I know--the *eshell* is not necessary too--its illustrative--its just an

And, many thanks to you too Konrad for your new org-eshell.el

Re: [Orgmode] Sorting table columns (*not* content)

[brian powell]

Jeff Horn seems to be explaining specifics of how to do some nitty-gritty
manipulations--he mentions (quoting the manual) methods for yanking, Ccxy

The methods Jeff expressed are useful for the question posed.

I recommend rectangle-kill and rectangle-yank--Cxrk and Cxry to solve this
(in a very simple albeit possibly faster or slower way--depending on how
many columns you want to move/sort---moving column/rectangle 3 to the 3rd
position in this case--took a few seconds)

I tested Juan's method/defun---works great!!
Thanks Juan

P.S. I did lose the hlines like you reported; but, to put the line back was
3 key strokes: |-Tab

Re: [Orgmode] how to reverse a region of outline items

[brian powell]

* A macro would definitely do this--a keyboard macro solution is simple:

To create a keyboard macro do something like this:
Cx ( etc. Cx ) ;  Mx name-last-keyboard-macroetc.

To me, Cx (.Cx )...--creating a keyboard macro seems to be the most
useful thing one can use Editor MACroS/Emacs for!

;-)

** The solution is simple because of the features of OrgMode--the function
of folding tree-nodes, makes it more simple than you might think:

*** Have the macro do something like this:
1. Fold everything up to just the major headings.
2. Go to just below * A and put a string like jjj--and/or Mx
set-mark--on its own line
3. Go down one row and do Ck.
4. MS  ==  EscapeShiftLessThanSign  ---i.e. have macro repeatedly go to the
top.
5. Cy
6. Cs jjj
7. Repeat 3-7.

(Make 2 macros: The first does steps 1 and 2 and then does Cu 1
macro-that-you-make-that-does-Ck-on-next-line-and-go-to-the-top ---i.e.
steps 3-6.
This way you have 1 macro call the other macro 1 times or until you run
out of lines/major sections whichever happens first.)

You can make a macro that does the above--or just the second part and do:
 Cu 1 Mx blah-new-macro-that-reverses-the-section-headings
--then it would process a 10k major-headings-long-document or halt and ring
the bell when you run out of major headings to process--DownArrow will hit
the EndOfFile.  Then you have a reusable macro that does what you want--with
all the subtrees/subsections just where they started--untouched.

I agree with Nicolas below, and his solution is generally what one might
seek; but, a keyboard macro here allows you to do what you described
without sorting or alphabetizing, etc.---the last major heading becomes the
first and the first major heading becomes the last, regardless of the
contents.  Once keyboard macros are named and placed in .emacs, they are
reusable.

Good luck.

 Hello,

 C-c ^ A will sort the list alphabetically, in reversed order.

 If you do not really have A, B, etc. you can, well, add marks
 (numbers) to items with the help of `org-apply-on-list', sort the list
 numerically (in reversed order, with C-c ^ N), then remove the marks.

 Here is an example sexp to mark list:

 (org-apply-on-list
  '(lambda (c)
(org-get-bullet)
(goto-char (match-end 0))
(insert (format  %s c))

Re: [Orgmode] table, moving cells

[brian powell]

Theres a very simple way to do this; its been available in EMACS as long as
I can remember--which is back to the late 80's--and OrgMode makes it even
easier since it  evens-up/covers-down/aligns columns in real-time: All you
have to do is:

Go to the bottom right corner of the cell or column you would like to move
and set a mark CS@, then go the the top right corner of the square cell or
rectangular region of cells you intend to move and do Cxk ==
cut-rectangle--then go to where you want to move the cell or rectangle and
do Cxry to do the yank-rectangle where you'd like to put it.

I just tested it--works fine!

 Example, with the cursor on '2' in the following table

 Hi Carsten

  I fail to see the use case for this.


 I have come across two use cases lately where I have been missing this
 feature: 1) in a timetable, swapping a cell or two, e.g., the title of a
 talk and the speaker, with next week's values; and 2) making a seating plan
 for a social event. In the latter, moving people about quick and easy is
 nice.

  Yes, this can
 be useful sometimes, and you can use `C-c C-x C-w' and
 `C-c C-x C-y' to cut and paste individual fields or
 even rectangular regions.


 Ok, thanks, I did not know about these.

  But for pushing a cell value
 to a neighboring cell, I don't see a frequent use that
 would call for a special command beyond what I listed above.
 Do you?


 I agree that it is not a frequent operation.

 For the seating plan, I ended up with lots of post-it notes on a wall,
 which worked just fine! :)

 Thanks again!
 Martin

  Is there any concept of being able to run multiple, simultaneous

  hours during the week at work, i.e., punch in and punch out.
 
  Then, while that clock is running, I would use the normal clocking
  functionality to keep track of time on specific projects.
 
  As it is, clocking into a new task clocks out of the current task.
 
  There may not be a way, but thought I'd ask!

 I do this by using a special clocktable block that reads an entire
 agenda.  Try this on for size:

 #+BEGIN: clocktable :maxlevel 3 :scope agenda :block thisweek
 #+END

 It adds up all time spent on various tasks and gives me a total.  I
 suppose you can't really have two clocks running at once, but this works
 great for me.
