OK, I think that would work.  To summarize, here are the different
outputs under MathJax and the other modes:

- MathJax mode:
  - Environment:
,
| \begin{align}
| \label{eq:org19c7f92}
| 1 + 1 = 0
| \end{align}
`
  - Link:
,
| link to \eqref{eq:org19c7f92}
`
- other modes, e.g. verbatim: (it is similar for the rest: dvipng,
  imagemagick, etc).:
  - Environment
,
| 
| 
| \begin{align}
| 1 + 1 = 0
| \end{align}
| 
| 
| 
| 1
| 
| 
`
  - Link:
,
| link to equation 1
`

The attached patch produces this on my test cases.

About the CSS caption:
> I'm not sure. Have you checked how captions in other parts of
> "ox-html.el"?

I looked at other structures:
- for figures, the caption is in a `figcaption' tag if HTML5 is used or
  in a paragraph, both under the figure,
- for tables, the caption is in a `caption' tag, at the top or bottom of
  the environment depending on `:html-table-caption-above',
- As far as I can tell, source blocks get no caption.

Since there does not appear to have a common convention, I think the
proposed output (see above with "equation-container", "equation" and
"equation-label" tags) would be fine, if nobody objects.  Some CSS puts
the label on the right side, as with LaTeX export or MathJax.  This only
applies to the non-MathJax modes.

I think I misunderstood what the caption does in ox-latex.  Here, in the
MathJax case, just I need to insert the `\label' inside the latex
environment, e.g. `\begin{equation}\label{org21321}' similar to what
`org-latex-latex-environment' does.  The caption itself (the equation
number) is always on the right of the equation, regardless of the mode
(MathJax or other), so this is variable is not needed anymore.


I hope the patch looks better now.  I have a few remaining questions:

- The `org-html--is-math-environment' function relies on
  `org-latex-math-environments-re' from ox-latex for the numbering
  (numbering only equations, ignoring other environments).  Is it
  acceptable?
- In non-MathJax modes, I currently pre-process the latex environment to
  change equation environments to their * version,
  e.g. "\begin{equation}" -> "\begin{equation*}".  This is to prevent
  the latex environment from adding its own labeling to the rendered
  image.  This feels like a hack.  Is there a better way to achieve
  this?
- The `org-html--insert-latex-environment-label' (the function that
  inserts `\label' inside the environment also feels like a hack.  I
  originally wanted to re-use the equivalent latex code, but maybe this
  is simpler.  Do you think we can do better?
- In the image modes (e.g. dvipng), I removed the following comment: ";;
  Do not provide a caption or a name to be consistent with `mathjax'
  handling."  I am not sure what it means and whether I should be
  concerned about it.
- I think I have been with messing this file enough now that I should
  add tests.  I didn't see any tests for ox-latex or ox-html.  Is there
  a reason for that?


Please let me know if you have any comment.

Thanks,

thibault

Re: [O] Org citations, CSL and citeproc-el

[Richard Lawrence]

Hi András and all: 

Sorry for the delay.  


András Simonyi  writes:

Another question is the syntax for specifying the bibliography 
to be used and, maybe, the location where the bibliography 
should be placed.  Org-ref (ab)uses links for these purposes as 
well. Was there a syntax proposal for these things too? 


As far as I know, there was not.  This was not settled because in 
order to settle it, you need to know a bit more about the backend. 
(Where is the citation data stored? do you have to get it from an 
external program? if so, which? etc. etc.)


I think there was some agreement that we can do this with option 
keywords.  There is an existing syntax for specifying 
bibliographies in contrib/ox-bibtex.el, which probably provides a 
good model:


#+BIBLIOGRAPHY: bibfilename stylename optional-options  When I was 
playing around with hooking up the citation syntax to an external 
citation processor, I was using something similar: I had keywords 
like


#+CSL_FILE: the-csl-style-file.csl +BIBDB: bibtex testdoc.bib 


in the header, and used

#+BIBLIOGRAPHY: here

to specify where the bibliography should be placed in the 
document.  That is obviously not the nicest solution, but the 
basic idea might be a good starting point.

[O] Feature request: #+INCLUDE: with anchors

[edgar]

Hello,

I have seen this syntax in markdown (one of the many versions):

!listing
path/to/file.ext
start=ini_keyword end=end_keyword

Here, ~file.ext~ is a source file, and both ~ini_keyword~ and 
~end_keyword~ are text strings in the text delimiting what should be 
included (responsibility of the writer to make sure they are unique). I 
think that having something like this in Org would be nice. I am aware 
of the ~:lines~ option, but having something like this would not require 
an update of the numeric reference every time the referenced file 
changes.


Thanks for the great work!

Re: [O] ox-bibtex

[Adonay Felipe Nogueira]

On a related topic, I wish there was a way for Org to export BibTeX
references to other formats besides LaTeX and PDF.

I once relied on some package, org-bibtex to do the trick along with a
set of Emacs Lisp scripts that were run with Babel ([1]), but found out
that I was doing more Lisp programming and actually embedding software
(a kind of functional data) to my presentations (a kind of
non-functional data) than doing my actual presentation, and also decided
to not use it anymore because people who were new to Org mode documents
and not tech experts would ask me how to do the same thing in their Org
mode documents and I would have to present them the monster I
created. :S

I've overlooked the fact that ox-bibtex is in contribs of org-mode

[O] ox-bibtex

It seems that the emacs-26.0.90 pretest, which uses org-version 9.1.2,

FWIW, org-latex-prefer-user-labels eluded me in the documentation. Now that you

it on my own.

I'll update org when I can.

Note that ‘org-structure-template-alist’ will change again.  There’s a

Hi Martin,

I discovered this only yesterday, when I started using org-mode from a git
checkout and the shortcuts stopped working. Turns out this functionality
now has to be enabled by loading the org-tempo library:
https://code.orgmode.org/bzg/org-mode/src/master/lisp/org-tempo.el. In
principle, you can reenable them just by adding (require 'org-tempo) in
your Emacs config. The first time I did this, I was getting an error which
seemed to be caused by the value of the org-structure-template-alist
variable. I hadn't modified it myself, but I went into its customize screen
and reset it to the default, and that fixed the problem.

Hope this helps,
