Hi, I realize I never responded to say thank you.

This is a big help, and I now have things working the way I like!

 More importantly, org-reveal allows the use of speaker notes, thus:

 #+BEGIN_NOTES

 whatever I put here

 #+ END_NOTES

 is exported as:

Re: [O] [PATCH] org-id-goto doesn't work if buffer is narrowed.

[John Kitchin]

It has always bugged me when clicking on an id link does not put the
point on the headline when narrowing is in place. Opening in a new
buffer might  be a nice compromise of preserving the restriction in
place, and getting to the point of interest. I think these are called
indirect buffers
(http://www.gnu.org/software/emacs/manual/html_node/emacs/Indirect-Buffers.html).

Re: [O] org-reveal questions

[Fabrice Popineau]

I switched to org-reveal from beamer.
Beamer clutters your slides with too much markup.
(I ended up with much more markup than text in my slides).

Moroever, Reveal offers features that no pdf reader offers at least under
windows :
- separate frame for notes, timer, next slide
- ability to synchronize other clients on the master display
(your students can connect and their slides move as you move yours)
And it is very quick to compile a deck of x100 slides, where beamer can
take minutes.

To answer the first question :
- load bootstrap in the  section of your slides
- then you can add div's with class col-xs-6 for example and split your
frame in 2 columns.

I load bootstrap, mathjax and some personal js and css. It is working
pretty well.
It is not as clean as beamer out of the box, but it is more efficient.
With a good css, it should be  as clean as beamer.

I agree. But, am I not explicitly asking to jump to the specified
item. I don't mind the widening, at least when the call is
interactive. I agree with you when some other code is calling it,
though.

You mean, display the entry in a new buffer, and any changes will be

I haven't been following this thread very lcosely, but hopefully this will
help:
org-reveal allows you to specify a local.css file (M-x customize-variable
org-reveal-extra-css).  I keep mine in ~/src/org-reveal/local.css, but you
should choose a location that works for you.  I use this file to define
extra css classes for nededs that reveal doesn't met out of the box.

This is a two step process.  In your local.css, put something like this:

.left p, .left ul, .left li {
text-align:left;
}

and then in your org file:

#+ATTR_HTML: :class left
** Slide Title

some slide content



I *think* this should work.  If it doesn't, please reply and I'll try to
help.

The response in my last email applies here too -- you will need to do some
css customization.

1. you will need to add css classes & ATTR_HTML headers; it's not too hard,
actually.  something like:
img.float-left {
float:left;
}

ATTR_HTML:  :class float-left

etc.

2. as above, but change the font'size element:
p.small {
fo-nt-size: 0.6em;
}

etc.
3. Getting the headers to move higher up is a little tricky bdecause
javascript is in charge of the vertical alignment; I am not quite satisfied
with the way that reveal.js handles this, and don't have a solution.

Eric's right -- you'll have to learn either CSS or latex, it's up to you
which one to invest in.  I use css in other work, so I've taken that
rouute; latex is still a foreign language to me.

Thank you, Rasmus, but I haven't updated anything lately, so I don't think it's 
the result of any org changes.

... which of course can be changed by customizing the theme ...

It seems that to get close to how you want your slides to look, you need
to customize the theme in either of beamer and reveal.

Depending on whether you prefer to do that in css/js or latex, you might
arrive there quicker.

Based on the backtrace, I think that if you do M-x load-library RET
ox-org RET your error should disappear.

If that’s the cause, the attached (draft) patch should give a better
error message in cases like this.

Yes, that did fix it. But I'm puzzled because my .emacs file contains:

(require 'ox-org)

Shouldn't that have the same effect?

Thanks, Nick. From the error, I'm guessing either a variable that's supposed to 
point to the backend got unset, or the backend
itself is missing.

Thank you so much Fabrice for your helpful reply.
would it be ok to ask to elaborate more on the technical terms such as

I don't know that much about markdown, and I know there are many different

I agree that widening a buffer that was narrowed on purpose can be
annoying, sometimes. Most times, I think I wouldn't mind the widening.
That said, I'm not quite sure what is the right fix for this.

I find it weird to have a subtly different thing happening depending
on whether or not the target buffer is narrowed -- entry shown in
normal buffer when no narrowing vs. entry shown in a special/indirect
buffer.

Also, given that no other part of org really uses indirect buffers, I
don't know if this function alone should make use of that feature.

Let me know what you think.

-- Puneeth

PS: I've patched my org sources to do indirect buffers for this, and
will try it out for sometime to see how it feels.

Org mode already does this aggressively and often. For instance, it
irrevocably widens all buffers associated with org-agenda-files when
generating the agenda. (To replicate, try narrowing to a headline in a
buffer and then calling the agenda.) The same is true of follow mode; it
widens a buffer once one moves to a line in the agenda corresponding to
that buffer. In other words, org currently does not go out of its way to
protect user's narrowed regions.

+1 on my part for widening a buffer if it contains a relevant id target.
If I click org-id-goto and the target is in my buffer, I want it to
widen that buffer.

Macros can output raw inline HTML code. If you want to generate any HTML
code, you can use some babel block to do that.

It’s not that Org isn’t trying to save narrows, it’s just that you found
another bug (sounds like a missing org-with-wide-buffer to me, but I
haven’t tried to reproduce your example).  It could of course also be that
the same logic is not applied in this case on purpose.

In Org 8.3, you'll (thankfully) not lose your narrow when you click C-c
C-c on a footnote reference outside the current narrow.  Also not when you
insert a new footnote.

Whether it would be better to use an indirect buffer, as John suggests, or
whether it would be possible to utilize the familiar interface of
org-src.el for "remote editing" (or viewing) I don’t know.

Yeah, I would prefer that.  Would that work for you or would still prefer
to have your buffer widened?

[O] Macro question

[Fabrice Popineau]

I was wondering if macros could be used to output raw html code, but that
doesn't seem to be the case.

Namely:

#+macro: bfoo @@html:@@
#+macro: efoo @@html:@@

The macros {{{bfoo}}} and {{{efoo}}} are expanded surrounded by  ...
.

This is quite a limitation. Is it the intended behavior?
If the reason is that the macro could output text that needs the  ...
, then
the problem is the point at which macros are expanded in the flow.
An option would be to allow #+html: in the macro, but that doesn't work.
The #+html:
directive gets straight on the output.

Sorry if this has already been discussed here.
(I vaguely remember some discussions about recursive macros)

I don't think it's inadequate, but I also don't know if this should be
part of ox-md in it’s present form.

The original md specification doesn’t seem to support this syntax:

 https://daringfireball.net/projects/markdown/syntax

(I searched for % and author).

Would it be recognized by say Github or Stack Exchange?  On Github
"^% Rasmus\n"  is printed as just that, so I guess not.

Perhaps it would be better to define a new backend, ox-md-pandoc.el, or
add a "#+MARKDOWN_FLAVOR" keyword to condition such insertions on.

Cheers,
Rasmus

Thank you.

However, `org-export-barf-if-invalid-backend' raises an error, not
a user-error. IOW, it doesn't need to be verbose: it is a bug if a user
sees it anyway.

I suggest to (require 'ox-org) where appropriate and fix the issue.
I didn't look closely at the problem so you know better than me where
this line should be added.

WDYT?

No problems.

I've determined tonight that it was working fine in org 8.2.10, but
the problem you report is in org 8.3.1. There are many changes in
ob-core.el, but little in ob-dot.el or ob-eval.el, so further
investigation is required. I'll continue plugging. I really like
building graphs using dot through org-mode, so I'd love to see this
fixed (e.g. I had to revert to LibreOffice Draw today!).

Please don't. They should be defconst and are kept as defvar for

Thank you for the patch.

However, "ox-md.el" is for Vanilla Markdown, where such constructs do
not exist. So it cannot be applied there.

ISTR there are a few others export back-ends in contrib/ that may use
this. You may also create ox-md-pandoc.el if it doesn't exist already.

[O] feature request: easier style attributes

[Matt Price]

OK, one more, again a repeat of an old request.

Pandoc Markdown has this incredibly easy way to specify html attributes (
http://pandoc.org/README.html#header-identifiers):


# My Header {#myid .class1 .class2}


I find this much easier to read, write, and maintain than the org-mode
equivalent:

#+ATTR_HTML: :id myid :class class1 class2
* My Header

I would love to have something like the pandoc syntax available within
org.  What do other people think, and how hard would this be to implement?

It's not obvious that org should change a—potentially—carefully selected
narrowed region.

Perhaps you could mimic the way org-edit-special works for this case.

If you want to do it more pragmatically, you could use something like
this (adjust the template as needed).

(add-to-list 'org-capture-templates
 '("d" "Deadline" entry
   (file "~/org/inbox.org")

Customizing reveal.js slides does require css and html knowledge. You
can change the theme (or link to your own custom stylesheet in the
header of your reveal html). You might also try searching online for
custom themes that meet your specifications.

Beamer is also great, but customizing beamer to look precisely the way
you want it requires knowledge of LaTeX.

In short, simple slide export from org-mode is fine if you are OK with
the existing themes, templates. But more customization that will
generally require knowledge of the relevant markup.

[O] [BUG] Use of period in org-read-date broken

[Matt Lundin]

The commit e802936f4b39f8b1e56cc015f34aa655565afe7f broke the use of the
period at the beginning of the minibuffer as a means to jump to the
current day.

Steps to replicate:

1. Evaluate (org-read-date)

2. Use Shift-Left to go to the previous date.

3. Type a period at beginning of minibuffer prompt.

Expected behavior:

The calendar should jump to the current day and no period should be
inserted in the minibuffer. That is the behavior that always worked in
the past and the behavior that is intended in lines 16772 to 16777 of
org.el.

Actual behavior:

A period is inserted in the minibuffer and the calendar does not jump to
the current day.

Here is the problematic commit:

--8<---cut here---start->8---

I may be wrong but I think you are asking too much from org-reveal.  If
you want this level of customisation, you may need to go to the HTML

This wouldn't cut it because CONTEXT is wrong when, e.g., point is in
a comment. I think you're after the VISUALLY argument from
`org-in-regexp'. But then, it would require to turn
`org-at-date-range-p' and `org-at-timestamp-p' into `org-in-regexp'
calls.

[O] feature request: best practices for speaker notes and incremental lists/elements

[Matt Price]

In writing ox-md-pandoc, I ad occasion to translate org-reveal's spearker
note syntax into html .  It revived an older concern of mine, that
ox-reveal and ox-deck have different ways of representing near-identical
features within org.

** Speaker notes

Speaker notes are represented thus for export to reveal.js:

#+BEGIN_NOTES
Here are my awesome notes
#+END_NOTES

and for export to deck.js:

* Notes :note:
Here are my awesome notes

-

** incremental lists/elements

incrementally-shown elements are produced thus in reveal:

** My Slide Header
#+ATTR_REVEAL: :frag (appear)
- list 1 is one click away
- list 2 is two clicks away

and in deck:

* My Slide Header
:Properties:
:STEP: t
:END:
- list 1 is one click away
- list 2 is two clicks away



I think the two exporters should use the same syntax! I especially think
that any future exporters should use a single, unified syntax, and that the
older exporters should eventualyl be changed to support that new syntax.
And finally, I think the new syntax should be as simple as humanly
possible.  So I'd like to suggest that the community decide on the best way
forward.

I don't really have an opinion as to which method is better; in fact, I
imagine there's probably a method tjat is better and simpler than any that
have been developed thus far.  Certianly I think what he have right now is
pretty awkward  But I think it's worth figuring out what we want to do, and
then implementing it.

And once we've done that, it wil lbe easier for me to add the proper
functionality to the md-pandoc exporter, too.

Thanks,

Matt

I agree that raw html can be output by macros, but it can easily break too.

At the moment :

-
#+macro: bfoo @@html:@@
#+macro: efoo @@html:@@

* Section

{{{bfoo}}}

Some text.

{{{efoo}}}
-

is exported as :

-

Section










Some text.







-

But :

-
#+macro: bfoo @@html:@@
#+macro: efoo @@html:@@

* Section

{{{bfoo}}}
Some text.
{{{efoo}}}
-

is exported as :

-

Section







Some text.




-

In the first case, the  ...  are quite annoying.
In the second case,  the  ...  is spurious, but at least it doesn't
break the structure.

I wonder if there is a way to guess where ox-html could avoid to emit
paragraphs.

Re: [O] Suppress export of Abstract block?

[John Kitchin]

use a filter (http://orgmode.org/worg/exporters/filter-markup.html) and
set that text to be ""?

This will probably clobber all special blocks. If you have more than
one, you need to check if it is an abstract block somehow, and return
the text unaltered if it isnt.

This is untested ;)

(defun ox-mrkup-filter-abstract
   (text back-end info)
   "")

you will need a derived backend, maybe something like:

(org-export-define-derived-backend 'my-html 'html
  :filters-alist
  '((:filter-special-block . ox-mrkup-filter-abstract)))

Then run
(org-export-to-file 'my-html "html-marked.html")
